Product details
Overview
ESD761DPYR from Texas Instruments is a single-channel, bidirectional TVS diode designed for I/O-level ESD protection in USB Power Delivery (USB-PD) and industrial control interfaces. It features ±15-kV IEC 61000-4-2 contact discharge rating, 1.1-pF typical I/O capacitance, 24-V working voltage (VRWM), 36.3-V clamping voltage at 1.8-A surge current, and operates across –55°C to +150°C.
For engineers reviewing the ESD761DPYR datasheet, ESD761DPYR pinout, ESD761DPYR application, or ESD761DPYR equivalent, key selection criteria include low-capacitance bidirectional clamping for high-speed signal integrity, robust 1.8-A IEC 61000-4-5 surge handling, compact X1SON (DPY) 1.0 mm × 0.6 mm footprint, and compatibility with USB-PD CC/SBU lines and 4–20 mA industrial I/O protection.
Technical Context
The ESD761DPYR functions as a passive, bidirectional clamping diode that remains in high-impedance state below ±24 V (VRWM) and triggers into low-dynamic-resistance conduction (RDYN = 0.53 Ω) during transients. Its snapback breakdown behavior (VBR = ±25.5 V min) ensures rapid response to ESD events while maintaining low leakage (<50 nA at ±24 V).
Designed specifically for placement at connector interfaces, it routes transient energy to ground via Pin 2 (GND), limiting voltage seen by downstream ICs to ≤36.3 V under 1.8-A 8/20 µs surge. The 1.1-pF line capacitance supports data rates up to 480 Mbps on D+/D− and CC lines without signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IEC 61000-4-2 Contact Discharge | ±15 kV - meets Level 4 immunity for direct human contact in industrial and USB-PD applications |
| Clamping Voltage (VCLAMP) | 36.3 V at 1.8 A (8/20 µs) - limits stress on protected USB-PD controller or ADC input |
| I/O Capacitance (CL) | 1.1 pF (typ) - enables use on USB 2.0 D+/D− and CC lines without signal integrity loss |
| Working Voltage (VRWM) | ±24 V - safely withstands VBUS short events and industrial supply rail transients |
| Dynamic Resistance (RDYN) | 0.53 Ω - ensures low-voltage overshoot during fast ESD pulses |
| Operating Temperature | –55°C to +150°C - supports deployment in automotive under-hood, PLC, and harsh industrial environments |
| Surge Current (IPP) | 1.8 A (8/20 µs) - provides IEC 61000-4-5 compliance for industrial I/O protection |
Pinout & Package
ESD761DPYR uses the X1SON (DPY) 2-pin no-lead package (1.00 mm × 0.60 mm, 0.45 mm max height), optimized for space-constrained USB-C and industrial sensor PCBs. The exposed thermal pad enhances power dissipation during surge events.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O | Protected signal line (e.g., CC1, SBU2, or 4–20 mA sense input); bidirectional path to GND during ESD |
| 2 | GND | Direct connection to system ground plane; critical for low-inductance transient return path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects both positive and negative polarity transients on same line without polarity constraints |
| Low dynamic resistance | 0.53 Ω minimizes clamping voltage overshoot during sub-nanosecond ESD events |
| Ultra-low capacitance | 1.1 pF preserves signal integrity on USB-PD CC/SBU and industrial analog I/O lines |
| High-temperature operation | Rated from –55°C to +150°C - suitable for extended-life deployment in sealed enclosures and motor drives |
| Compact X1SON footprint | 1.0 mm × 0.6 mm saves >50% board area vs. SOD-523 (DYA) used by ESD751 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD751DYAR | Higher capacitance (1.6 pF), higher surge rating (2.8 A), larger SOD-523 (DYA) package (1.6 mm × 0.8 mm) | Better suited for VBUS power rail protection where space allows and higher surge margin is required | Select ESD751DYAR when 2.8-A IEC 61000-4-5 capability is mandatory and board area permits larger footprint |
| SMA6J24A | Unidirectional, 24-V standoff, 38.9-V clamping at 1.8-A, SMA package (4.5 mm × 2.7 mm) | Requires external series resistor for bidirectional protection; unsuitable for differential or AC-coupled signals | Choose SMA6J24A only for cost-sensitive, non-bidirectional DC power rail protection where size is secondary |
Compared with ESD751DYAR and SMA6J24A, ESD761DPYR delivers optimal balance of ultra-small X1SON footprint, true bidirectional operation, and USB-PD–ready 1.1-pF capacitance-making it the preferred choice for space-constrained, high-speed interface protection where layout efficiency and signal fidelity are critical.

FAQ
What is the maximum clamping voltage of ESD761DPYR under IEC 61000-4-5 surge conditions?
The ESD761DPYR clamps to 36.3 V when subjected to a 1.8-A, 8/20 µs surge waveform per IEC 61000-4-5. This value is measured between the I/O and GND terminals during unidirectional current flow and represents the peak voltage imposed on protected circuitry during worst-case surge events. The low clamping level ensures compatibility with 3.3-V and 5-V logic interfaces downstream of the ESD761DPYR.
Can ESD761DPYR be used for bidirectional signal lines like USB D+ and D−?
Yes, ESD761DPYR is explicitly designed for bidirectional signal protection and is rated for ±15-kV IEC 61000-4-2 contact discharge in both polarities. Its symmetrical breakdown (VBRF = +25.5 V min, VBRR = –25.5 V min) and 1.1-pF capacitance make it suitable for USB 2.0 D+/D− lines operating up to 480 Mbps. Layout best practice requires placing ESD761DPYR as close as possible to the USB-C connector with minimal trace length.
What is the thermal resistance (RθJA) of ESD761DPYR in its X1SON (DPY) package?
The junction-to-ambient thermal resistance (RθJA) of ESD761DPYR in the X1SON (DPY) package is 282.3°C/W, measured under standard JEDEC JESD51-7 conditions. This value assumes a 2-layer PCB with 1-in² copper pour under the exposed thermal pad. For sustained surge duty cycles, designers should verify junction temperature using RθJB (98.3°C/W) and actual board copper area to ensure TJ remains within –55°C to +150°C limits.
Does ESD761DPYR require any external components for basic ESD protection functionality?
No, ESD761DPYR is a standalone, passive TVS diode requiring no external resistors, capacitors, or biasing. It operates solely between the protected I/O line (Pin 1) and system ground (Pin 2). However, for optimal performance, TI recommends routing Pin 2 directly to a low-inductance ground plane and placing the device within 3 mm of the protected connector to minimize parasitic inductance that could degrade clamping response.
Is ESD761DPYR compliant with RoHS and REACH regulations?
Yes, ESD761DPYR is RoHS-compliant (lead-free, homogeneous material content meets EU Directive 2011/65/EU) and REACH-conformant (SVHC substances below threshold per EC 1907/2006). The device carries "NIPDAU | NIPDAUAG" lead finish and is rated Level-1-260°C-UNLIM for moisture sensitivity, enabling standard reflow assembly without baking. Full compliance documentation is available in TI's official product folder for ESD761DPYR.
