Product details
Overview
PESD24VV2BAT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed to safeguard two in-vehicle network lines (e.g., CAN-FD and FlexRay) with 24 V reverse standoff voltage, 33 V clamping at 1 A, and 6 pF capacitance. It meets AEC-Q101, supports 175 °C junction temperature, and delivers 23 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the PESD24VV2BAT-QR datasheet, PESD24VV2BAT-QR pinout, PESD24VV2BAT-QR application, or PESD24VV2BAT-QR equivalent, this page provides verified electrical parameters, validated SOT23 terminal mapping, automotive bus-specific use cases, and qualified alternative parts for CAN-FD, SENT, and FlexRay line protection.
Technical Context
This bidirectional TVS diode integrates two cathode-referenced protection channels sharing a common cathode (Pin 3), enabling symmetrical clamping on differential bus lines without requiring external biasing. Its low 6 pF capacitance minimizes signal integrity impact on high-speed automotive serial buses up to 5 Mbps.
The device operates within a -55 °C to +175 °C ambient range and sustains 2.6 A peak pulse current (8/20 µs), with dynamic resistance of 0.7 Ω ensuring rapid transient energy diversion away from sensitive transceivers during ESD events per IEC 61000-4-2 and ISO 10605 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Blocks normal bus operating voltage while remaining non-conductive during CAN-FD (±12 V differential) or SENT (5 V supply) operation. |
| Clamping Voltage | 33 V (typ.) at 1 A - Limits transient voltage across protected IC pins to safe levels below transceiver absolute maximum ratings. |
| ESD Withstand | 23 kV (IEC 61000-4-2 contact) - Survives repeated human-body-model ESD strikes without degradation in automotive cabin environments. |
| Diode Capacitance | 6 pF (typ.) - Enables use on 5 Mbps CAN-FD and 1 Mbps FlexRay without measurable rise-time distortion or signal reflection. |
| Junction Temperature | 175 °C max - Supports placement near powertrain ECUs or under-hood modules where ambient temperatures exceed 125 °C. |
| Peak Pulse Current | 2.6 A (8/20 µs) - Handles surge energy from coupled transients on long harness runs without thermal runaway. |
| Dynamic Resistance | 0.7 Ω - Ensures fast voltage collapse during ESD events, reducing stress time on downstream CAN transceivers. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height. RoHS-compliant, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Connects to first protected line (e.g., CANH); forms low-impedance path to common cathode during positive transients. |
| 2 | K2 (Cathode 2) | Connects to second protected line (e.g., CANL); enables independent clamping for differential bus pairs. |
| 3 | CC (Common Cathode) | Reference node tied to system ground or chassis; completes conduction path for both channels during ESD events. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel architecture | Single SOT23 package protects two independent bus lines (e.g., CANH/CANL), reducing PCB area vs. discrete diodes. |
| Automotive qualification | AEC-Q101 qualified with 175 °C Tj rating ensures reliability in engine control, ADAS, and body electronics modules. |
| Low-capacitance design | 6 pF capacitance prevents signal overshoot or timing skew on CAN-FD (up to 5 Mbps) and SENT (single-edge nibble transmission). |
| High ESD robustness | 23 kV IEC 61000-4-2 contact discharge rating allows direct integration at connector interfaces without additional shielding. |
| Thermal stability | Derated peak pulse power maintains >80% capability at 125 °C junction temperature, supporting under-hood deployment. |
Applications
| CAN-FD Bus Protection | FlexRay Bus Protection |
|---|---|
Use Scenario: Protecting high-speed CAN-FD communication between ADAS domain controller and radar sensor over 2 m cable harness. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed directly at connector entry point, clamping ±8 kV ESD pulses before reaching TJA1044GK transceiver. Use Value: Maintains <1 ns response time and 6 pF loading to preserve 5 Mbps bit timing integrity while surviving 23 kV contact discharge. | Use Scenario: Safeguarding FlexRay physical layer in powertrain control unit exposed to alternator load dump and ignition noise. IC Role / Device Role / Timing Role: Dual-line protector shunting transients from both FlexRay A and B channels to common ground, preventing latch-up in MR2002 transceivers. Use Value: 24 V VRWM blocks nominal 28 V supply rail voltage while clamping surges to ≤33 V, avoiding transceiver overvoltage shutdown. |
| SENT Sensor Interface | Automotive Body Control Module |
Use Scenario: ESD protection for single-wire SENT output from pressure sensor in HVAC actuator subjected to technician handling. IC Role / Device Role / Timing Role: Single-channel mode (Pin 1–3) used to protect SENT data line against contact ESD in cabin assemblies. Use Value: 6 pF capacitance avoids pulse-width distortion on 125 µs base period signals; 23 kV rating exceeds ISO 10605 C=150 pF/R=330 Ω requirement. | Use Scenario: Dual-line protection for LIN and CAN sub-buses in door module exposed to door slam ESD and RF coupling from key fob antennas. IC Role / Device Role / Timing Role: Shared cathode configuration enables compact layout protecting both LIN (Pin 1–3) and CANL (Pin 2–3) with one device. Use Value: Reduces BOM count by 1 vs. discrete diodes; AEC-Q101 qualification ensures 15-year field life in cyclic temperature/humidity environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD24VS2WQ-13-F | Same SOT23-3 package, 24 V VRWM, but 12 pF capacitance and 38 V clamping at 1 A. | Higher capacitance limits use to ≤125 kbps CAN; less suitable for CAN-FD or SENT. | Select when cost sensitivity outweighs high-speed signal integrity requirements. |
| TPD2E001DRYR | 2-channel, 5.5 V VRWM, 0.6 pF capacitance, not AEC-Q101 qualified. | Only rated for 125 °C Tj; unsuitable for under-hood or powertrain locations. | Choose only for non-automotive industrial CAN nodes with strict low-capacitance needs. |
Compared with ESD24VS2WQ-13-F and TPD2E001DRYR, PESD24VV2BAT-QR uniquely balances 6 pF capacitance, 23 kV ESD rating, AEC-Q101 qualification, and 175 °C operation-making it the sole option qualified for CAN-FD and FlexRay in engine bay or ADAS modules.

FAQ
What is the maximum continuous reverse voltage this device can block?
The PESD24VV2BAT-QR has a reverse standoff voltage (VRWM) of 24 V, meaning it remains non-conductive up to this DC or steady-state AC voltage across its terminals. This rating ensures compatibility with 24 V automotive systems and 12 V CAN-FD buses without leakage-induced power loss or false triggering.
How does the common cathode configuration affect circuit layout?
The shared cathode (Pin 3) requires connection to a low-inductance ground plane, enabling simultaneous clamping of both protected lines (Pins 1 and 2) during differential or common-mode transients. This eliminates need for separate ground traces and reduces PCB loop area, critical for maintaining ESD suppression effectiveness per ISO 10605 test setup requirements.
Can this device protect both CAN-H and CAN-L simultaneously?
Yes-Pins 1 and 2 connect directly to CAN-H and CAN-L respectively, with Pin 3 grounded. During an ESD event on either line, current flows through the corresponding diode to the common cathode, clamping voltage to ≤33 V while preserving differential signaling integrity due to matched channel characteristics and 6 pF capacitance.
Is the 23 kV ESD rating applicable to both contact and air discharge?
The 23 kV rating applies specifically to IEC 61000-4-2 contact discharge testing. Air discharge rating is not specified in the datasheet; however, the same device achieves 23 kV under ISO 10605 (C = 150 pF, R = 330 Ω) contact discharge, confirming robustness across major automotive ESD test standards.
