Product details
Overview
PESD24VV1BAX from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one signal line against IEC 61000-4-2 ESD events up to ±30 kV and 8/20 µs surges up to 3.5 A peak pulse current, with 24 V reverse stand-off voltage and 14–17 pF capacitance at 1 MHz - deployed in automotive infotainment interfaces.
For engineers reviewing the PESD24VV1BAX datasheet, PESD24VV1BAX pinout, PESD24VV1BAX application, or PESD24VV1BAX equivalent, key selection criteria include clamping voltage under 33 V at 3.5 A, ultra-low leakage (<1 nA at 24 V), AEC-Q101 qualification, and low-capacitance protection for bidirectional low-speed data lines.
Technical Context
This dual-cathode bidirectional TVS diode uses symmetrical avalanche breakdown to clamp both positive and negative transients without polarity dependence, enabling protection of AC-coupled or differential signaling paths where voltage swings occur above and below ground.
Its 0.2 Ω dynamic resistance and 33 V clamping at 3.5 A (8/20 µs) ensure rapid energy diversion while maintaining signal integrity on lines such as CAN FD physical layer stubs, USB 2.0 D+/D−, or LIN bus, with junction temperature rated to 150 °C for under-hood automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 24 V - maximum continuous working voltage before conduction begins, ensuring no interference during normal signal operation. |
| Clamping Voltage | 33 V at 3.5 A (8/20 µs) - peak voltage seen by protected circuit during worst-case surge, limiting stress on downstream ICs. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - withstands real-world human-body-model ESD events without degradation. |
| Diode Capacitance | 14–17 pF at 1 MHz, 0 V bias - low enough to avoid signal distortion on low-speed interfaces up to ~10 Mbps. |
| Leakage Current | <1 nA at 24 V - negligible DC loading on high-impedance sensor or reference lines. |
| Dynamic Resistance | 0.2 Ω - ensures fast transient response and minimal voltage overshoot during sub-nanosecond ESD pulses. |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard - validated for temperature cycling, humidity, and mechanical robustness in automotive environments. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked side indicated by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Connects to protected line; forms first half of symmetrical clamping path for negative transients. |
| 2 | Cathode (Diode 2) | Connects to same protected line; forms second half for positive transients - pins are electrically tied internally to ground via PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Single-device protection of AC-coupled or floating lines without external biasing or polarity constraints. |
| Ultra-Low Capacitance | 14–17 pF enables use on USB 2.0, CAN, LIN, and I²C without signal rise-time degradation or reflection. |
| Sub-1 nA Leakage | Preserves accuracy in high-impedance analog sensor inputs and battery-powered standby circuits. |
| AEC-Q101 Qualification | Validated for automotive under-hood and cabin applications including infotainment, body control, and ADAS sensor interfaces. |
Applications
| Automotive Infotainment | CAN FD Physical Layer |
|---|---|
Use Scenario: Protecting HDMI or LVDS display interface cables in head units exposed to ESD during service or user interaction. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed at connector entry point, clamping ±30 kV discharges before reaching SerDes ICs.

Use Scenario: Shielding CAN FD transceiver pins (CANH/CANL) from ESD during vehicle assembly or field maintenance. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp mounted directly at connector, referenced to chassis ground. Use Value: Maintains CAN FD bit timing integrity up to 5 Mbps by limiting added capacitance to ≤17 pF and clamping to ≤33 V. |
| Industrial Sensor Interface | Consumer USB 2.0 Port |
Use Scenario: Safeguarding RS-485 or analog sensor outputs in factory automation controllers subject to cable discharge events. IC Role / Device Role / Timing Role: Standoff-rated protector on bidirectional differential pair, operating within ±24 V common-mode range. Use Value: Enables reliable 250 kbps communication over 1200 m cable runs while surviving 30 kV contact ESD without parameter shift. |
Use Scenario: ESD hardening of USB 2.0 D+ and D− lines on portable media players and docking stations. IC Role / Device Role / Timing Role: Dual-cathode diode placed inline with each data line, grounded through shortest possible trace. Use Value: Passes USB-IF ESD compliance testing with <1 nA leakage preserving pull-up/pull-down bias stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (30 pF), lower clamping (27 V @ 3.5 A), same SOD-323 package. | Better for lower-voltage systems (≤12 V VRWM); less suitable for 24 V automotive signal rails. | Select when clamping voltage priority outweighs capacitance sensitivity, e.g., legacy CAN 2.0B designs. |
| Vishay VEML6030X01 | Photodiode + integrated signal conditioning - not an ESD protector; incompatible function. | Not applicable - optical sensor, not TVS device. | Exclude: functional mismatch; VEML6030X01 is ambient light sensor, not ESD protection component. |
Compared with NUP4105MR6T1G, PESD24VV1BAX offers tighter capacitance control (14–17 pF vs. 30 pF) and higher VRWM (24 V vs. 12 V), making it preferable for 24 V automotive data lines where signal bandwidth and voltage margin are critical.

FAQ
What is the maximum operating temperature for PESD24VV1BAX?
The junction temperature rating is 150 °C, and the ambient operating range is −55 °C to +150 °C. This allows deployment in engine bay or powertrain control modules where thermal cycling and sustained high temperatures occur, provided PCB thermal relief and copper pour meet Nexperia's recommended layout guidelines.
Can PESD24VV1BAX protect high-speed interfaces like USB 3.0 or HDMI 2.0?
No - its 14–17 pF capacitance causes unacceptable insertion loss and return loss above ~100 MHz. It is validated for low-speed interfaces only, including USB 2.0 (480 Mbps), CAN FD (5 Mbps), and LIN (20 kbps). For USB 3.0 or HDMI, use dedicated low-capacitance arrays with ≤0.5 pF per line.
Is PESD24VV1BAX unidirectional or bidirectional?
PESD24VV1BAX is explicitly bidirectional, with two cathodes (Pin 1 and Pin 2) connected internally to form symmetrical clamping for both positive and negative transients. Its V-I curve (Fig. 3) shows identical breakdown behavior in both polarities, enabling protection of AC-coupled or floating signal lines.
Does the marking code 'EF' correspond to PESD24VV1BAX on the device body?
Yes - Table 4 confirms that PESD24VV1BAX is marked with 'EF' on the top surface of the SOD323 package. The marking bar adjacent to Pin 1 indicates the cathode orientation, consistent with standard SOD323 polarity conventions used across Nexperia's ESD portfolio.
