SI1563DH-T1-E3 - 20V Complementary N/P MOSFET Array | Vishay
MPN: SI1563DH-T1-E3 ✓ فعالSI1563DH-T1-E3 جائزہ
An N/P complementary MOSFET pair is a single-package integration of one N-channel and one P-channel enhancement-mode MOSFET, allowing designers to build push-pull, level-shift, load-switch, and small-signal analog switches with a single SOT-363 footprint. Both transistors share identical 20 V drain-source breakdown ratings and on-resistance characteristics, so they can be used as direct half-bridge switches, analog signal multiplexers, and low-side/high-side complementary switching pairs in portable, battery-powered electronics.
The SI1563DH uses Vishay's TrenchFET Gen III technology to deliver sub-1 V gate threshold operation, suitable for direct interface with 1.8 V microcontrollers and modern low-power MCUs without external gate drivers. Low on-resistance per square millimeter minimizes conduction losses, while a 570 mW power budget supports load switching in handheld and wearable form factors. The compact SC-70-6 footprint reduces PCB area by more than 50% compared to two discrete SOT-23 MOSFETs.
Typical applications include load switching in portable devices, power-rail multiplexing, level shifting between low-voltage MCUs and 5 V peripherals, battery protection circuits in single-cell Li-ion systems, and small-signal analog switching for audio and sensor paths. The complementary topology enables half-bridge and H-bridge motor drive stages for vibration motors and small DC fans.
When laying out the SI1563DH, place the input/output traces symmetrically around the package center, connect the exposed paddle to a copper pour that also serves as thermal spreading, and keep gate traces short to prevent dv/dt-induced turn-on. The SC-70-6 footprint is electrically identical to a SOT-363 footprint and is fully compatible with standard reflow profiles up to 260 C peak.

عام استعمالات
SI1563DH-T1-E3 کے لیے موزوں ہے 6 ایپلیکیشنs: Portable/Battery Load Switch, Logic Level Shift / Signal Translation, H-Bridge / Small DC Motor Driver, Small-Signal Analog Switch / Multiplexer, LED Driver / Backlight Dimming, IoT Sensor Power Rail Multiplexer.
Portable/Battery Load Switch
The SI1563DH-T1-E3 is well suited as a battery load switch in single-cell Li-ion portable devices. The 20 V VDS rating provides ample headroom above the 4.2 V maximum Li-ion charge voltage, while the 1.13 A N-channel and 880 mA P-channel can each handle typical sub-1 W peripheral loads (radios, sensors, displays). The complementary pair enables a single IC to drive both high-side and low-side switching paths, simplifying the power mux topology. Gate threshold below 1.8 V allows direct MCU control without an additional gate driver, which is critical in space-constrained wearables.

Logic Level Shift / Signal Translation
The SI1563DH-T1-E3 functions as a compact bidirectional logic level shifter between 1.8 V MCUs and 3.3 V or 5 V peripherals. The N-channel serves as the high-side pull-down switch while the P-channel acts as the high-side pull-up, replicating the classic BSS138 plus BSS84 topology in a single 6-pin SC-70-6 package. This reduces board area by more than 60% versus two discrete SOT-23 parts and ensures matched on-resistance across both directions. Typical use cases include I2C, UART, and SPI level translation in IoT endpoints and wearables.

H-Bridge / Small DC Motor Driver
The SI1563DH-T1-E3's complementary N/P topology makes it a natural fit for half-bridge stages in small H-bridge motor driver circuits for vibration motors, micro fans, and tiny DC pumps. By using two SI1563DH devices, a full H-bridge is realized in just two SC-70-6 packages (12 pins total), which is far more compact than four discrete SOT-23 MOSFETs. The 1.13 A N-channel and 880 mA P-channel provide matched switching speeds for clean PWM operation at 20-50 kHz.

Small-Signal Analog Switch / Multiplexer
The SI1563DH-T1-E3 is frequently deployed in low-frequency analog signal multiplexing for audio signal routing, sensor channel selection, and test-mux circuits. The N+P complementary pair provides low on-resistance (typically under 1 ohm at VGS=4.5 V) in a bidirectional signal path, achieving -60 dB crosstalk at audio bandwidths. The SC-70-6 package allows placement directly adjacent to the MCU ADC or op-amp input, minimizing trace-induced noise.

LED Driver / Backlight Dimming
The SI1563DH-T1-E3 is used as a 20 V-tolerant PWM-controlled LED driver for small backlight strings and indicator LEDs in portable devices. The N-channel low-side switch can sink up to 1.13 A per LED string, sufficient for 100-200 mA class backlights. The P-channel can implement high-side PWM dimming for common-anode RGB indicators without requiring an additional charge pump or bootstrap circuit, simplifying the BOM and shrinking the PCB.

IoT Sensor Power Rail Multiplexer
The SI1563DH-T1-E3 powers up multiple low-power IoT sensors sequentially to reduce quiescent current in battery-powered sensor nodes. The N-channel switches the ground return while the P-channel switches the supply rail, allowing zero-leakage isolation of inactive sensor branches. Typical battery savings of 30-70% are achieved in multi-sensor designs for smart-home, environmental monitoring, and asset-tracking applications.

ڈیزائن نوٹس
Estimated: at maximum continuous drain current on the N-channel (1.13 A) with on-resistance of ~0.4 ohm and 20 V VDS, the SI1563DH-T1-E3 dissipates roughly 0.5 W under worst-case switching conditions. The SC-70-6 package is rated for 570 mW total device dissipation on a JEDEC 1-square-inch 2 oz copper test board. Keep both N- and P-channel conduction duty cycles under 50% in continuous operation, and stitch thermal vias under the SC-70-6 land pattern to a continuous ground pour so both internal transistors share the same thermal mass.
Route gate traces to pins 1 (G1) and 6 (G2) before placing any other signal trace; the high-impedance gates are vulnerable to dv/dt-induced turn-on if the trace length exceeds 5 mm. Place the input/output RC snubber within 3 mm of each drain pin when driving inductive loads such as small motors or relays. Keep the N-channel drain trace and P-channel source trace on opposite sides of the package so the internal body-diode current path does not cross sensitive analog signals.
Do not exceed the 20 V VDS rating on either transistor: even brief transients above 24 V can permanently shift the gate threshold. When using the SI1563DH as a level shifter, ensure that VGS does not exceed +/- 8 V at any point during hot-plug or ESD events; add a 100 kohm pull-down on the gate if the driving MCU pin is high-impedance during power-up. Avoid using both channels at full rated current simultaneously - the 570 mW package dissipation limit must be shared, so at 0.5 W per channel the die temperature would exceed the 150 C junction rating.
