TPD1E01B04DPLR Descripción general
An ESD protection diode is a discrete semiconductor device placed between an exposed connector or signal line and the protected circuitry. It provides a low-impedance transient-current path during electrostatic discharge events, while remaining effectively transparent during normal operation. In the broader hierarchy, the TPD1E01B04 belongs to the TVS diode, ESD suppressor, discrete semiconductor, and circuit-protection categories.
The low 0.18 pF capacitance minimizes loading on high-speed data lines. Texas Instruments states that the device can protect interfaces operating up to 20 Gbps when the circuit is implemented with suitable signal-integrity practices. The bidirectional structure supports protection in either signal polarity, while the ±3.6 V working-voltage specification places the device on low-voltage connector pins.
The manufacturer lists maximum IEC 61000-4-2 Level 4 ESD dissipation capability and ±15 kV protection. The DPL package occupies only 0.6 mm by 0.3 mm according to the distributor listing, helping designers conserve PCB area in dense USB-C, Thunderbolt, and other high-speed interface layouts.
Typical applications include USB Type-C connector ESD protection, Thunderbolt 3 interface protection, high-speed data-line protection, and compact consumer or industrial equipment. The device is most useful when its protection placement is close to the connector and its capacitance is acceptable to the target signal path.
The primary design consideration is signal integrity: place the device near the connector entry, use short and properly referenced connections, and verify that the added capacitance does not degrade edge rate or insertion loss. Do not infer ratings or package details not stated in the manufacturer or distributor sources.

Aplicaciones típicas
TPD1E01B04DPLR es adecuado para 6 aplicacións: USB Type-C Connector Protection, Thunderbolt 3 Interface Protection, High-Speed Data-Line Protection, USB-C Power and Control Pins, Compact Consumer Electronics, Industrial High-Speed Connectors.
USB Type-C Connector Protection
TPD1E01B04DPLR fits USB Type-C protection because its 0.18 pF typical capacitance limits loading on high-speed data lines while its bidirectional structure handles positive and negative ESD transients. TI identifies the device for USB Type-C and specifies protection up to ±15 kV under the stated ESD testing context. Place the diode close to the connector entry and route the ESD return directly to the intended protection reference. The design benefit is compact protection that does not intentionally dominate the connector's high-frequency signal budget, although the final margin depends on trace impedance and the rest of the channel.
Recomendado
Thunderbolt 3 Interface Protection
The TPD1E01B04DPLR is specifically identified by Texas Instruments for Thunderbolt 3 protection, where very low parasitic capacitance is important at multi-gigabit signaling rates. Its 0.18 pF typical value helps avoid unnecessary loading, while the ±15 kV ESD rating addresses exposed connector hazards. The device should be placed before the signal reaches sensitive logic, with short protection paths and controlled reference-plane connections. Signal-integrity validation is still required because connector launches, shielding, via structures, and receiver capacitance determine the actual channel margin.
Recomendado
High-Speed Data-Line Protection
Use TPD1E01B04DPLR when an exposed high-speed line requires compact bidirectional ESD protection without adding substantial capacitance. The manufacturer describes the family as suitable for interfaces up to 20 Gbps, and the listed 0.18 pF typical capacitance is the principal reason it can be considered for high-speed paths. Placement near the connector is critical because the protection loop must be shorter and more direct than the protected signal path. Validate insertion loss, return loss, and edge-rate degradation in the assembled board rather than relying on the diode capacitance alone.
Recomendado
USB-C Power and Control Pins
TPD1E01B04DPLR can protect selected low-voltage USB-C signal or control pins where the system requires bidirectional transient suppression. Its ±3.6 V working-voltage specification makes it appropriate for circuitry operated within that range, while the 15 V typical clamp voltage provides a defined transient response in the supplied distributor listing. Because the package is only 0.6 mm by 0.3 mm, it helps conserve board area around dense Type-C receptacles. Check the actual signal voltage, DC bias, leakage, and clamp behavior in the complete protection solution.
Recomendado
Compact Consumer Electronics
TPD1E01B04DPLR is suitable for compact consumer products that expose USB or similar high-speed connectors to touch-generated ESD events. Its small DPL footprint supports space-constrained layouts, while the low typical capacitance helps preserve fast-edge communications. The device is intended to be placed at the connector boundary rather than deep inside the system, allowing the protected trace to continue toward the host or peripheral controller. Product-level compliance testing remains necessary because enclosure grounding, chassis geometry, and cable behavior influence the total ESD performance.
Recomendado
Industrial High-Speed Connectors
The TPD1E01B04DPLR can support ESD protection in industrial equipment with accessible high-speed connectors, provided the operating voltages and channel requirements match its ±3.6 V working-voltage and low-capacitance characteristics. Its -40 °C to +125 °C listed range covers a broad range of ambient conditions, and the surface-mount DPL package supports automated assembly. Industrial equipment may present harsher ESD coupling than desktop systems, so engineers should verify enclosure bonding, ground-plane continuity, connector launches, and system-level test procedures.

Diferenciadores clave
- Low capacitance for high-speed protection (frente a TPD1E01B04DPYR)
- Compact 0.6 mm by 0.3 mm DPL footprint (frente a TPD1E01B04DQAR)
- Explicit USB Type-C and Thunderbolt 3 positioning (frente a TPD1E01B04DPLT)
Notas de diseño
Place the protection diode immediately adjacent to the connector shell or signal entry, and route the ESD return through a short, low-impedance path to the designated protection reference. The transient loop should be smaller than the signal-loop area; otherwise parasitic inductance can reduce the effective clamp voltage during fast ESD events. Follow the TI DPL land pattern rather than relying on a generic two-pad footprint.
The listed 0.18 pF typical capacitance is low, but it is not zero. Confirm that the added loading is acceptable for the target edge rate, insertion loss, return loss, and impedance-controlled trace. For USB Type-C or Thunderbolt layouts, preserve the intended reference plane and avoid long stubs between the connector, protection device, and receiver. Validate with the complete assembled channel rather than the isolated component.
Do not substitute the DPL package with a DPYR or DRL package based only on the TPD1E01B04 family name. The supplied search results identify TPD1E01B04DPYR as 2-X1SON DPY and TPD1E01B04DQAR as SOT-563 DRL, which are different footprints. Also verify the latest TI ordering table because R, T, Y, and other suffixes can identify different package or reel configurations.
Información de cumplimiento
The supplied data identifies IEC 61000-4-2 Level 4 as an ESD test standard, but it does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for this specific ordering code.
