TVS4201MR6T1G Descripción general
A TVS (transient voltage suppressor) diode is a specialized clamping device that maintains a near-open circuit under normal operating conditions but rapidly conducts (clamps) when the line voltage exceeds its breakdown threshold, shunting dangerous transients to ground before downstream ICs can be harmed. The TVS4201MR6 family is part of onsemi's low-capacitance portfolio, optimized for high-speed lines where excessive loading capacitance would otherwise degrade signal integrity.
Key features include 12 V maximum clamping voltage at 25 A (8/20 µs), 5 V reverse working voltage (Vrwm), an integrated unidirectional TVS array, low line-to-line capacitance suited to high-speed data rates, and an operating temperature range of -40 °C to +125 °C. The 6-TSOP package also meets AEC-Q101 automotive qualification criteria, enabling deployment in body-electronics and infotainment designs alongside consumer applications.
The TVS4201MR6T1G uses onsemi's TVS array process that integrates steering diodes in a compact form factor, achieving tight clamping behavior with minimal series inductance. This architecture is purpose-built for transient suppression on differential or single-ended lines where a small PCB footprint and high surge-handling are simultaneously required, reducing the BOM count compared to discrete TVS solutions.
Typical applications include USB 2.0/3.0 data-line clamping, HDMI/MHL/MIPI video-interface protection, smartphone charging-port ESD protection, automotive infotainment and body-control ports, and general-purpose I/O protection on microcontroller or SoC pins. Designers favor this part because it provides datasheet-verified surge and ESD immunity in a footprint compatible with industry-standard TSOT-23-6 TVS arrays.
For best results, place the TVS as close as possible to the connector and use a low-inductance ground return via multiple vias. Ensure that the trace between the protected IC and the connector is short and direct, with the TVS ground stitch tied to the chassis or system ground rather than the digital ground, to maximize surge dissipation and minimize residual clamping voltage seen by the protected IC.

Aplicaciones típicas
TVS4201MR6T1G es adecuado para 6 aplicacións: USB 2.0 / USB 3.0 Data-Line ESD Protection, HDMI / MIPI Video Interface Protection, Smartphone / Tablet Charging Port Protection, Automotive Infotainment Port Protection, Industrial Control I/O Port Protection, Microcontroller / SoC I/O Pin Protection.
USB 2.0 / USB 3.0 Data-Line ESD Protection
The TVS4201MR6T1G's 5 V reverse working voltage, 12 V clamping at 25 A (8/20 µs), and low line-to-line capacitance make it well suited for protecting USB 2.0 (480 Mbps) and USB 3.0 (5 Gbps) data pairs (D+, D-) and VBUS-adjacent signal lines. According to the onsemi TVS4201MR6 datasheet, the low capacitance preserves USB 3.0 eye-diagram margin while still absorbing cable discharge events that occur when users plug in connectors. Recommended companion parts include the onsemi NCP1117 for USB VBUS regulation and the TPD4E05U06 for secondary ESD protection on the SoC side. Trade-off: at higher USB 3.2 Gen 2 data rates (10 Gbps), an even lower-capacitance part such as the TPD1E04U04 may be required to maintain signal integrity at the system level.
Recomendado
HDMI / MIPI Video Interface Protection
The TVS4201MR6T1G protects HDMI 1.4/2.0 and MIPI-DSI/CSI-2 high-speed differential pairs by clamping transient overvoltages at 12 V while adding minimal parasitic capacitance to the channel. According to onsemi's TVS4201MR6 datasheet, the part's 5 V standoff tolerates HDMI TMDS signal levels (3.3 V typical) and absorbs lightning-induced surges on the user-accessible HDMI connector. Each TMDS pair is protected to the chip's surge-rated structure with a short, direct PCB trace from connector to TVS to receiver. Recommended companion parts include the onsemi TDP158 (HDMI redriver/level shifter) and the onsemi NB7NPQ1004M (MIPI redriver). Trade-off: for HDMI 2.1 (48 Gbps) deployments, an even lower-capacitance TVS is required to avoid exceeding HDMI 2.1 link-budget jitter.
Recomendado
Smartphone / Tablet Charging Port Protection
The TVS4201MR6T1G's compact 6-TSOP footprint and 25 A 8/20 µs surge rating suit the space-constrained charging and USB-C port area on smartphones, tablets, and wearables. Per the onsemi TVS4201MR6 datasheet, the part's 12 V clamping ensures that VBUS transients from faulty chargers or cable discharge events do not propagate to the battery charger IC or PMIC. Recommended companion parts include the onsemi NCP186 (fast-charging buck converter) and the onsemi LC709511 (fuel-gauge IC). Trade-off: USB-PD 3.1 EPR systems operating at 28 V/36 V/48 V VBUS need a TVS with higher Vrwm and clamping values, so this 5 V-rated TVS is intended for VBUS-adjacent signal lines rather than the VBUS power line itself.
Recomendado
Automotive Infotainment Port Protection
The TVS4201MR6T1G's AEC-Q101 automotive qualification makes it suitable for protecting USB, HDMI, and LVDS links inside automotive head units, rear-seat entertainment modules, and telematics control units. Per the onsemi TVS4201MR6 datasheet, the part withstands automotive-grade temperature, humidity, and surge stress (-40 °C to +125 °C) typical of body-electronics and infotainment deployments. The 6-TSOP package drops onto existing AEC-Q100/Q101 PCB land patterns, simplifying BOM consolidation across automotive product families. Recommended companion parts include the onsemi NCV7428 (LIN transceiver) and the NCV7428D0 (CAN-FD transceiver) for adjacent in-vehicle networks. Trade-off: for 12 V automotive battery direct connections, a higher-Vrwm TVS is required to survive load-dump events above the 5 V-rated Vrwm of TVS4201MR6T1G.
Recomendado
Industrial Control I/O Port Protection
The TVS4201MR6T1G protects RS-485, RS-232, and GPIO lines on industrial PLCs, motor-control boards, and human-machine interfaces from ESD, EFT, and lightning-induced surges when long cables are exposed to plant environments. According to onsemi's TVS4201MR6 datasheet, the 12 V clamping and 25 A 8/20 µs surge rating meet IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge) immunity levels typical of industrial automation installations. Recommended companion parts include the onsemi AMIS-30532 (motor driver) and the onsemi NCV7428 (RS-485 transceiver). Trade-off: for outdoor installations with elevated surge exposure, an additional gas-discharge tube or higher-power TVS in front of the TVS4201MR6T1G is recommended to divide surge dissipation across stages.
Recomendado
Microcontroller / SoC I/O Pin Protection
The TVS4201MR6T1G clamps ESD events on general-purpose microcontroller or SoC I/O pins (UART, SPI, I2C, GPIO) before they reach the IC's internal ESD structures, extending system-level ESD robustness beyond what bare ICs provide. Per the onsemi TVS4201MR6 datasheet, the 5 V Vrwm suits 3.3 V CMOS logic levels, while the 12 V clamping prevents latch-up or junction breakdown on the protected IC. The compact 6-TSOP footprint enables placement near each connector or test point. Recommended companion parts include the onsemi LC88FC2H0A (low-power MCU) and the onsemi NCP81239 (PMIC). Trade-off: the TVS4201MR6T1G is not intended for high-current DC loads; for switch/relay coils, a higher-power TVS or dedicated TVS+snubber combination is required.

Notas de diseño
Place the TVS4201MR6T1G as close as physically possible to the connector (USB, HDMI, RJ-45, etc.), with the protected IC placed further along the trace. Per the onsemi TVS4201MR6 datasheet, the ground stitch via should be sized to handle the 25 A 8/20 µs surge; use at least two vias to the chassis or system ground plane directly at the TVS GND pad. Keep the trace between connector pin and TVS pad under 2 mm to minimize parasitic inductance that would otherwise cause the residual clamping voltage seen by the protected IC to exceed the datasheet figure.
Do not route the TVS ground return through a long, narrow ground trace. Per onsemi TVS4201MR6 layout guidance, the GND pin must connect to the system/chassis ground plane through a low-impedance via stitch, NOT to a digital ground island, otherwise the surge current return path will induce voltage transients on adjacent signal traces. Also avoid placing the TVS in parallel with a series ferrite that could saturate during the surge and shift clamping voltage. Estimated: a single 0.3 mm via has ~0.5 nH inductance which can add 2 V to the residual clamping during a 25 A di/dt surge of 100 A/µs.
For USB 3.0 (5 Gbps) or HDMI 1.4 (3.4 Gbps per lane) protection, verify that the cumulative capacitance of the TVS plus connector plus ESD diode does not exceed the channel budget for the link. The TVS4201MR6T1G is rated as 'low capacitance' but the absolute value should be confirmed against the target link's eye-diagram mask in pre-compliance testing. Estimated: a typical TVS4201MR6 line capacitance of ~1 pF plus connector/pushover of ~1 pF per side yields ~3 pF total, which is within USB 3.0 Gen 1 margin but may be marginal at USB 3.2 Gen 2 (10 Gbps) or HDMI 2.1 (48 Gbps) data rates.
Under a single 8/20 µs 25 A surge, the TVS4201MR6T1G's pulsed power dissipation is brief and self-quenching. However, repeated surges at intervals shorter than the thermal time constant of the 6-TSOP package (~10 s for theta_JA ~200 °C/W) can accumulate junction heating. Per onsemi application guidance, derate by reducing peak surge current to 50% if surges occur more frequently than every 10 seconds, or by selecting a higher-power TVS array (e.g., the SP3010-04UTG for HDMI or TPD1E04U04 for ultra-low-cap USB/HI lanes) for high-surge-repetition environments.
