ESD761DPYR 概述
An ESD protection diode is a discrete semiconductor device placed on an interface line to divert electrostatic-discharge energy away from sensitive circuitry. In the broader hierarchy, it belongs to the TVS diode and ESD suppressor families, which are discrete semiconductors used for circuit protection. ESD761DPYR is intended to be placed close to the protected connector or board entry point so that the transient current has a short path to ground or the protected supply rail.
The verified product information identifies 1.1 pF capacitance, a 24 V nominal working-voltage class, ±15 kV ESD capability, a typical 36.3 V clamp voltage, and a 1.8 A peak pulse current for an 8/20 microsecond surge waveform. The TI overview also describes suitability for USB-PD and industrial I/O applications and states that the device is suitable for VBUS protection. The Mouser listing describes the device as a 1.1 pF, 24 V, 15 kV single-channel bidirectional ESD protection diode.
Because the device has only two terminals, the protection network is straightforward: connect the protected signal or power node to one terminal and the appropriate return or protection node to the other terminal. The exact connection depends on the interface and board return strategy, so the manufacturer datasheet and application guidance should control placement. Do not substitute a generic TVS diode without checking working voltage, capacitance, clamping behavior, and package dimensions.
Typical uses include USB-C and USB power-delivery connectors, LIN interfaces, audio lines, GPIO inputs, industrial control boards, and external sensor connections. The 1.1 pF capacitance is particularly useful on lines where lower parasitic loading is desired, although actual signal-integrity performance still depends on trace geometry, connector construction, and the impedance of the complete interface.
For PCB implementation, place the diode close to the connector and route the transient return path directly to the appropriate ground or rail structure. Keep the protected trace short and avoid allowing ESD current to flow through sensitive digital return paths. Confirm the maximum working voltage and pulse ratings against the actual signal amplitude and surge environment. This page consolidates the verified manufacturer and distributor information, application context, and design cautions while clearly identifying parameters not supplied in the verified data.

典型应用
ESD761DPYR 适用于 6 应用s: USB-C Power-Delivery Protection, LIN Bus Input Protection, Audio Interface Protection, Industrial GPIO Input Protection, External Sensor Cable Protection, VBUS and External Power-Path Protection.
USB-C Power-Delivery Protection
The ESD761DPYR fits USB-C and USB power-delivery connectors where transient protection must add little signal capacitance. Texas Instruments identifies ESD761 as a 1.1 pF, ±24 V, ±15 kV ESD protection device for USB-PD, making it suitable for placing near the connector entry point. The device can help divert electrostatic discharge away from the controller and power-path circuitry. Its verified 36.3 V typical clamp voltage and 1.8 A 8/20 microsecond pulse rating should be compared with downstream absolute maximum ratings. Actual USB-C design validation still requires checking VBUS, CC, data-line routing, connector geometry, and the system return path.
推荐
LIN Bus Input Protection
ESD761DPYR is appropriate for slower-speed LIN interfaces where the protected conductor can receive electrostatic discharge from an external harness or connector. The Mouser listing identifies the part as a 24 V, 15 kV single-channel bidirectional LIN-related protection device, while the TI overview identifies slower-speed industrial I/O as a suitable use case. The 1.1 pF capacitance helps limit added line loading. Place the diode close to the connector and use a return path that keeps the pulse out of sensitive transceiver ground paths. Verify LIN voltage levels, bus transients, and the complete transceiver protection strategy.
推荐
Audio Interface Protection
The ESD761DPYR can protect audio connectors and low-speed analog signal inputs from electrostatic discharge while limiting capacitance-related signal disturbance. Its 1.1 pF capacitance is small compared with many general-purpose protection networks, and the bidirectional ±24 V working-voltage class suits interfaces that can see both polarities. Place it at the connector-facing side of the board and route the return directly to the intended protection ground. Confirm that the audio source, amplifier, codec, or connector can tolerate the verified 36.3 V typical clamp voltage during an ESD event.
推荐
Industrial GPIO Input Protection
ESD761DPYR is useful on industrial GPIO, button, and control-signal inputs that connect to external equipment. TI explicitly lists industrial I/O among the slower-speed applications suited to the low-capacitance ESD751 and ESD761 family. The bidirectional arrangement handles both polarity directions, while the 2-pin surface-mount package supports compact protection near the connector. A practical design should place the device before the trace reaches sensitive logic, provide a low-inductance return, and verify the external cable length and ESD exposure. Do not use the diode as a substitute for overvoltage, reverse-polarity, or surge-current protection.
推荐
External Sensor Cable Protection
The ESD761DPYR can be placed at the board edge to protect a low-speed sensor or instrumentation input from contact discharge when a cable is connected or disconnected. Its 1.1 pF capacitance helps preserve the input impedance and signal bandwidth, while the ±15 kV contact and air-gap ratings provide a defined ESD protection target. The device should be close to the connector rather than deep inside the analog front end, so the transient is intercepted before it reaches sensitive components. Confirm the sensor's voltage range, grounding scheme, cable length, and the required IEC 61000-4-2 system-level test conditions.
推荐
VBUS and External Power-Path Protection
ESD761DPYR is identified by TI as suitable for VBUS protection in USB and industrial interface applications. Its ±24 V working-voltage class can be relevant to low-voltage power-entry nodes, while the 1.8 A 8/20 microsecond pulse specification must be checked against the actual surge environment and downstream power circuitry. The device is an ESD-protection element, not a complete surge suppressor or fuse. Use it with the system's power-path, overvoltage, reverse-polarity, and current-limiting components, and route its return current through a deliberate PCB structure.

设计说明
Place ESD761DPYR immediately adjacent to the connector or board entry point, with the protected trace kept short and the protection return routed directly to the intended ground or rail structure. The verified package is a 2-pin X1SON (DPY) device, so orientation and land-pattern details must follow the TI package drawing. Do not rely on package-body appearance alone; verify pin numbering, terminal polarity, and assembly orientation before release to manufacturing.
The 24 V working-voltage class is not the same as the 36.3 V typical clamp voltage. During a transient, downstream circuitry must tolerate the clamp behavior while the signal or rail remains within its own absolute maximum ratings. For a continuous VBUS or power-path design, add the required overvoltage, reverse-polarity, and surge-current protection separately; ESD761DPYR should be treated as an ESD interface-protection element rather than the sole power protection device.
ESD761DPYR provides 1.1 pF capacitance, which is appropriate for slower-speed USB-PD, LIN, audio, GPIO, and industrial I/O signals. However, total interface loading includes connector parasitics, protection-device capacitance, trace capacitance, and the receiving input impedance. For high-speed signals, evaluate the complete channel with an eye diagram or impedance analysis instead of assuming that a 1.1 pF device is sufficient for the system.
