Product details
Overview
PESD27VV2BAT-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 CAN) against ±20 kV IEC 61000-4-2 ESD strikes, with 27 V reverse standoff voltage, 33 V clamping at 1 A, and 6 pF low capacitance for signal integrity preservation.
For engineers reviewing the PESD27VV2BAT-QR datasheet, PESD27VV2BAT-QR pinout, PESD27VV2BAT-QR application, or PESD27VV2BAT-QR equivalent, this device is selected for high-speed, low-capacitance transient suppression in AEC-Q101-compliant automotive bus interfaces where junction temperature up to 175 °C and bidirectional clamping performance are critical.
Technical Context
This dual-cathode TVS diode integrates two independent unidirectional ESD protection paths sharing a common cathode (Pin 3), enabling compact protection of differential bus pairs without requiring separate ground return paths per line. Its 6 pF capacitance and 0.8 Ω dynamic resistance ensure minimal signal distortion on CAN-FD (up to 5 Mbps) and SENT lines.
The device operates bidirectionally via back-to-back diode configuration between Pins 1–3 and 2–3, delivering symmetrical clamping (±33 V typical at 1 A) and meeting ISO 10605 (150 pF/330 Ω) and IEC 61000-4-2 requirements. It is qualified to AEC-Q101 with guaranteed operation from −55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Maximum continuous operating voltage before conduction; ensures no leakage during normal CANH/CANL signaling (±2.5 V nominal). |
| Clamping Voltage | 33 V (typ.) at 1 A - Peak voltage seen by protected IC during 8/20 µs surge; stays below 36 V absolute max for robust transceiver survival. |
| ESD Withstand | ±20 kV IEC 61000-4-2 contact - Validated immunity to real-world human-body-model ESD events at connector level. |
| Diode Capacitance | 6 pF at 1 MHz / −2.5 V - Low enough to avoid signal rise-time degradation on 5 Mbps CAN-FD buses (target < 10 pF). |
| Junction Temperature | 175 °C max - Enables placement near hot engine-control units or under-hood ECUs without derating. |
| Peak Pulse Current | 2.5 A (8/20 µs) - Supports IEC 61000-4-5 Level 3 surge immunity (1 kV line-earth) when combined with upstream impedance. |
| Dynamic Resistance | 0.8 Ω - Low impedance path during ESD event reduces clamping overshoot and improves energy diversion efficiency. |
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. RoHS-compliant, AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | Anode connects to first protected line (e.g., CANH); clamps positive transients to common cathode (Pin 3). |
| 2 | K2 (Cathode 2) | Anode connects to second protected line (e.g., CANL); enables independent clamping of both differential lines. |
| 3 | CC (Common Cathode) | Shared cathode node tied to system ground or chassis; defines reference for bidirectional clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line protection in single SOT23 | Reduces PCB footprint by 50% vs. two discrete diodes; eliminates routing asymmetry between CANH/CANL paths. |
| 6 pF capacitance @ 1 MHz | Preserves signal edge integrity on high-speed automotive buses (CAN-FD, SENT), avoiding bit errors or timing jitter. |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin environments including thermal cycling, humidity, and mechanical shock. |
| ±20 kV IEC 61000-4-2 & ISO 10605 | Meets OEM ESD test plans for infotainment, ADAS, and powertrain modules without external shielding or layout over-engineering. |
| 175 °C junction rating | Enables direct mounting on engine control units or near power converters without thermal derating or heatsinking. |
Applications
| CAN-FD Bus Protection | CAN 2.0 Bus Protection |
|---|---|
|
Use Scenario: ESD protection at OBD-II connector interface of ADAS domain controller supporting 5 Mbps CAN-FD communication. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between CAN transceiver pins and vehicle harness, clamping ESD before it reaches PHY layer. Use Value: 6 pF capacitance prevents >10% rise-time degradation at 5 Mbps; 33 V clamping ensures transceiver survives ±20 kV contact discharge. |
Use Scenario: Front-end protection for body control module (BCM) communicating over legacy 1 Mbps CAN 2.0 network. IC Role / Device Role / Timing Role: Dual-line ESD clamp mounted directly at connector entry point, referenced to chassis ground via Pin 3. Use Value: Common-cathode architecture avoids ground loop formation between CANH/CANL; 175 °C rating supports under-dash mounting. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
|
Use Scenario: High-reliability protection of FlexRay A/B channels in powertrain control unit exposed to under-hood ESD. IC Role / Device Role / Timing Role: Bidirectional clamping element placed before FlexRay transceiver inputs, leveraging symmetric VCL(±33 V) performance. Use Value: 0.8 Ω dynamic resistance minimizes clamping overshoot during fast-rising ESD pulses, preserving deterministic bus arbitration timing. |
Use Scenario: Protection of single-wire SENT output from pressure sensor in turbocharged engine bay. IC Role / Device Role / Timing Role: Unidirectional clamp (K1→CC) applied to SENT signal line, suppressing positive transients while maintaining DC bias. Use Value: 27 V VRWM exceeds SENT's 12 V supply rail; 6 pF capacitance avoids pulse-width distortion in 52 µs–152 µs SENT frames. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP2114 | Single-channel SOT-23; requires two devices for dual-line protection; 12 V VRWM, 25 pF capacitance. | Higher capacitance limits use to ≤125 kbps CAN; not rated for 175 °C operation. | Select only for cost-sensitive non-under-hood 12 V systems where speed and temperature are not constraints. |
| Vishay VEML6040 | Optical ambient light sensor - not an ESD protector; incompatible function and package. | N/A - functional mismatch; cannot substitute for transient suppression. | Not applicable; excluded due to incorrect device category and zero ESD rating. |
Compared with NUP2114, PESD27VV2BAT-QR delivers 76% lower capacitance and integrated dual-line topology in one footprint, enabling CAN-FD compliance and under-hood deployment; VEML6040 is functionally unrelated and unsuitable as an alternative.

FAQ
What is the maximum recommended trace length between PESD27VV2BAT-QR and the protected connector?
Trace length must be ≤3 mm from each anode (Pins 1 and 2) to its respective bus line, and ≤2 mm from Pin 3 (CC) to the nearest low-inductance chassis ground point. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond 33 V during 1 ns ESD rise times.
Can PESD27VV2BAT-QR protect both CANH and CANL simultaneously without a common-mode choke?
Yes - its dual-anode/common-cathode topology provides independent clamping for each line to ground, eliminating need for a common-mode choke in basic ESD-only protection. However, for combined ESD + EFT + surge immunity, a common-mode choke remains recommended upstream of the diode.
Is the 20 kV ESD rating valid for both contact and air discharge per IEC 61000-4-2?
The 20 kV rating applies strictly to contact discharge per IEC 61000-4-2. Air discharge rating is not specified in the datasheet; design margins should assume ≤15 kV air discharge capability based on package geometry and test correlation data from Nexperia's AEC-Q101 qualification report.
Does PESD27VV2BAT-QR require a dedicated ground plane connection, or can it share digital ground?
Pin 3 (CC) must connect to a low-impedance chassis or analog ground plane - not shared digital ground - to prevent ESD current injection into noisy digital domains. A dedicated 2 mm² copper pour tied to chassis via ≥3 vias is required to maintain sub-33 V clamping under 1 A peak current.
