Product details
Overview
ESD751DYARQ1 from Texas Instruments is a single-channel bidirectional TVS diode for IEC 61000-4-2 level 4 ESD protection, rated for ±22-kV contact/air-gap discharge, 24-V working voltage, 1.6-pF typical I/O capacitance, and 2.8-A IEC 61000-4-5 (8/20 µs) surge current - deployed in USB-PD VBUS and CC line protection.
For engineers reviewing the ESD751DYARQ1 datasheet, ESD751DYARQ1 pinout, ESD751DYARQ1 application, or ESD751DYARQ1 equivalent, key selection criteria include clamping voltage (36.5 V at 2.8 A), dynamic resistance (0.6 Ω), operating temperature range (–55°C to +150°C), low leakage (<50 nA at ±24 V), and SOD-523 (DYA) package compatibility with AOI inspection.
Technical Context
The ESD751DYARQ1 operates as a passive bidirectional clamping diode with snapback behavior triggered above ±25.5 V breakdown voltage. Its low dynamic resistance ensures tight clamping during transients, while its 1.6-pF capacitance supports signal integrity on USB-PD control lines (CC1/CC2, SBU1/SBU2) up to 480 Mbps.
Designed for automotive-grade reliability (AEC-Q100 qualified), it sustains 2.8-A surge current per IEC 61000-4-5 and maintains <50 nA leakage at ±24 V across –55°C to +150°C - enabling robust protection in industrial and automotive USB-PD power delivery systems without active biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | ±24 V - withstands sustained DC or AC signals up to 24 V without conduction, protecting against VBUS short events. |
| Clamping Voltage (VCLAMP) | 36.5 V at 2.8 A (8/20 µs) - limits transient voltage seen by downstream USB-PD controller during surge events. |
| I/O Capacitance (CL) | 1.6 pF (typical) - preserves signal integrity on CC/SBU lines, supporting USB-PD communication up to 480 Mbps. |
| ESD Rating (IEC 61000-4-2) | ±22-kV contact & air-gap - exceeds Level 4 immunity requirement for harsh industrial and automotive environments. |
| Surge Current (IPP) | 2.8 A (8/20 µs) - handles high-energy surges on VBUS or control lines per IEC 61000-4-5 standard. |
| Dynamic Resistance (RDYN) | 0.6 Ω - enables low-voltage clamping and fast response to ESD transients without thermal runaway. |
| Operating Temperature | –55°C to +150°C - certified for under-hood automotive and wide-temperature industrial applications. |
Pinout & Package
SOD-523 (DYA) package: 1.60 mm × 0.80 mm body, 0.77 mm max height, leaded 2-pin surface-mount outline compatible with automatic optical inspection (AOI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O | Bidirectional protected signal terminal - connects to USB-PD CC, SBU, or D+/D– line requiring ESD clamping. |
| 2 | GND | Ground reference terminal - must be routed with low-inductance path to system ground plane for effective transient shunting. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Protects both positive and negative polarity transients on same line - eliminates need for dual-diode configurations on USB-PD control signals. |
| Low dynamic resistance | 0.6 Ω enables stable clamping at 36.5 V under 2.8-A surge - reduces stress on downstream USB-PD controller ICs. |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C ambient) - validated for automotive USB-PD charging ports and infotainment interfaces. |
| Leaded SOD-523 package | Enables AOI-compatible manufacturing - improves yield and traceability in high-volume automotive electronics assembly. |
| Ultra-low leakage | <50 nA at ±24 V - minimizes standby power loss in always-on USB-PD detection circuits. |
Applications
| USB-PD VBUS Protection | USB-PD CC Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD761DPYR | Smaller X1SON (DPY) package (1.0 × 0.6 mm), lower capacitance (1.1 pF), reduced surge rating (1.8 A), same ±22-kV ESD rating. | Better suited for space-constrained USB-PD CC lines where layout area is limited and 1.8-A surge margin suffices. | Select ESD761DPYR when board space is critical and peak surge current requirements are ≤1.8 A; ESD751DYARQ1 remains preferred for VBUS-level protection. |
| TPD2E001DRYR | Same SOD-523 package, but lower VRWM (±5.5 V), higher capacitance (11 pF), and lower ESD rating (±8-kV contact). | Intended for low-voltage, high-speed data lines (e.g., I²C, UART), not 24-V USB-PD or industrial I/O. | Not suitable as direct alternative: TPD2E001DRYR lacks required 24-V standoff and ±22-kV ESD rating - use only for sub-6-V signal rails. |
Compared with ESD761DPYR, ESD751DYARQ1 offers higher surge current capability (2.8 A vs. 1.8 A) and larger PCB footprint tolerance, making it more robust for VBUS and industrial power-line protection; compared with TPD2E001DRYR, it delivers 4× higher ESD immunity and 4.4× higher working voltage - essential for automotive and industrial USB-PD deployment.

FAQ
What is the maximum continuous reverse voltage rating for ESD751DYARQ1?
The ESD751DYARQ1 has a reverse stand-off voltage (VRWM) of ±24 V, meaning it blocks up to 24 V in either polarity under normal operating conditions without entering conduction - critical for safe operation on USB-PD VBUS and industrial 24-V control lines. This rating is confirmed in Section 6.6 of the SLVSH10C datasheet and ensures no leakage-induced power loss or false triggering during steady-state operation of ESD751DYARQ1.
Does ESD751DYARQ1 meet AEC-Q100 automotive qualification requirements?
Yes, ESD751DYARQ1 is AEC-Q100 qualified (Grade 1: –40°C to +125°C ambient), with full test documentation including HTOL, TC, and ESD validation per the automotive stress test plan. The "Q1" suffix explicitly denotes automotive qualification, and the device is listed in TI's qualified versions addendum - confirming ESD751DYARQ1 is approved for use in automotive USB-C charging systems and infotainment interfaces.
What is the clamping voltage of ESD751DYARQ1 under IEC 61000-4-5 surge conditions?
The ESD751DYARQ1 clamps to 36.5 V when subjected to a 2.8-A, 8/20 µs surge waveform per IEC 61000-4-5 - measured between I/O and GND with polarity reversal. This value is specified in Table 6-6 of the SLVSH10C datasheet and ensures protected ICs (e.g., USB-PD controllers) remain within safe operating voltage margins during high-energy transients, directly validating ESD751DYARQ1's role in system-level surge resilience.
Can ESD751DYARQ1 be used on USB 2.0 D+ and D– differential pairs?
Yes, ESD751DYARQ1 is suitable for D+/D– protection due to its 1.6-pF typical capacitance and bidirectional clamping, which preserves signal integrity up to 480 Mbps. However, placement must follow TI's layout guidelines: one ESD751DYARQ1 per line (D+ and D– each require individual devices), mounted directly at the USB connector with minimal trace length - as verified in Figure 8-1 and Section 8.2.2 of the ESD751DYARQ1 datasheet.
What is the thermal resistance (RθJA) of ESD751DYARQ1 in its SOD-523 package?
The junction-to-ambient thermal resistance (RθJA) of ESD751DYARQ1 in the DYA (SOD-523) package is 746.3°C/W, as specified in Section 6.5 of the SLVSH10C datasheet. This value assumes standard JEDEC 2-layer board conditions and confirms ESD751DYARQ1 can safely dissipate transient energy without exceeding 150°C junction temperature during repeated ESD events - critical for reliability in thermally constrained automotive modules.
