Product details
Overview
PESD2CANFD27VT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed for bidirectional transient suppression on CAN-FD and CAN bus lines. It features 27 V reverse standoff voltage, 33 V clamping voltage at 1 A, 6 pF capacitance, AEC-Q101 qualification, and 20 kV IEC 61000-4-2 ESD immunity - enabling robust signal integrity in high-speed in-vehicle networks.
For engineers reviewing the PESD2CANFD27VT-QR datasheet, PESD2CANFD27VT-QR pinout, PESD2CANFD27VT-QR application, or PESD2CANFD27VT-QR equivalent, this device delivers low-capacitance, high-temperature (175 °C) protection optimized for CAN-FD physical layer interfaces where timing margin, bus reliability, and layout-constrained placement are critical.
Technical Context
This dual-cathode TVS diode implements a common-cathode configuration with two independent protection channels (K1 and K2) referenced to CC (pin 3), enabling symmetrical clamping of differential transients on paired bus lines without requiring external biasing. Its 6 pF capacitance per channel minimizes signal distortion on CAN-FD's up to 5 Mbps data rates.
The device operates within a -55 °C to +175 °C ambient range and sustains 2.5 A peak pulse current (8/20 µs), with dynamic resistance of 0.8 Ω ensuring rapid voltage clamping during ESD events. It meets both IEC 61000-4-2 (20 kV contact) and ISO 10605 (20 kV, 150 pF/330 Ω) standards, validated under AEC-Q101 stress testing for automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 27 V - Ensures no conduction during normal CAN-FD bus operation (±2.5 V common-mode, ±40 V fault tolerance). |
| Clamping Voltage | 33 V at 1 A - Limits transient voltage to safe levels below CAN transceiver absolute maximum ratings (typically 40–70 V). |
| Diode Capacitance | 6 pF - Preserves signal edge integrity and minimizes bit error rate on 5 Mbps CAN-FD buses. |
| ESD Withstand | 20 kV IEC 61000-4-2 - Protects against human-body-model ESD events at connector interfaces. |
| Junction Temperature | 175 °C - Supports placement near powertrain ECUs and under-hood modules with minimal derating. |
| Peak Pulse Current | 2.5 A (8/20 µs) - Handles surge transients per IEC 61000-4-5 Level 3 (1 kV line-to-ground). |
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; optimized for automated placement and reflow soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of Channel 1 | Connects to protected line 1 (e.g., CANH); conducts transient current to common cathode during positive overvoltage. |
| 2 (K2) | Cathode of Channel 2 | Connects to protected line 2 (e.g., CANL); enables independent clamping of differential transients without shared anode path. |
| 3 (CC) | Common Cathode | Reference node for both channels; must be connected directly to low-inductance chassis or system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel common-cathode topology | Enables compact, matched protection of differential bus pairs (CANH/CANL) with single-component footprint and minimized loop inductance. |
| 6 pF capacitance matching (±0.5%) | Ensures balanced signal propagation delay between channels, preserving differential mode integrity and reducing common-mode noise coupling. |
| AEC-Q101 qualified | Validated for automotive use across temperature cycling, humidity, mechanical shock, and ESD stress - eliminating need for additional qualification effort. |
| Low dynamic resistance (0.8 Ω) | Reduces clamping voltage overshoot during fast-rising ESD pulses (<1 ns rise time), improving protection margin for sensitive transceivers. |
Applications
| Automotive CAN-FD Bus Protection | Automotive CAN Bus Protection |
|---|---|
Use Scenario: ESD protection at OBD-II connector interface of ADAS domain controller supporting 2 Mbps CAN-FD communication. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed <1 cm from connector pins to clamp ±8 kV contact discharge before reaching CAN transceiver. Use Value: Prevents latch-up or permanent damage to TJA1044G transceiver while maintaining <1 ns added propagation delay due to 6 pF loading. |
Use Scenario: Front-end protection for body control module (BCM) communicating via legacy 500 kbps CAN over 3 m harness. IC Role / Device Role / Timing Role: Dual-line ESD clamp on CANH/CANL lines upstream of common-mode choke and transceiver input. Use Value: Maintains signal rise/fall times <500 ns and eliminates false triggering caused by >15 kV ESD-induced ground bounce. |
| FlexRay Bus Protection | SENT Sensor Interface Protection |
Use Scenario: Transient suppression on FlexRay A/B differential pair in powertrain ECU operating at 10 Mbps. IC Role / Device Role / Timing Role: Low-capacitance TVS array protecting differential signaling lines against ESD and load dump-induced surges. Use Value: Enables compliance with FlexRay physical layer specification (≤10 pF per line) while delivering 20 kV ESD immunity. |
Use Scenario: Single-wire SENT sensor interface (e.g., pressure sensor) exposed to engine bay ESD events. IC Role / Device Role / Timing Role: Channel 1 protects SENT data line; Channel 2 grounds shield or supply return to suppress common-mode transients. Use Value: Prevents bit errors during SENT frame transmission by limiting transient-induced voltage excursions to <33 V at sensor IC input. |
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 |
|---|---|---|---|
| ON Semiconductor NUF2221MUTAG | 24 V VRWM, 35 V VCL at 1 A, 12 pF capacitance, SOT-363 package (6-pin), higher parasitic inductance. | Requires larger PCB area; less suitable for space-constrained CAN-FD routing due to 2× footprint and higher capacitance. | Select when dual-channel discrete layout flexibility is needed and 12 pF loading is acceptable for ≤1 Mbps CAN. |
| Infineon ESD224-BI0201 | 24 V VRWM, 30 V VCL at 1 A, 5.5 pF capacitance, DFN1006-3 package (0.6 mm × 1.0 mm), no common-cathode pinout. | Independent anode/cathode terminals per channel require separate ground paths, increasing layout complexity and ground loop risk. | Prefer for ultra-compact layouts where 0.6 mm × 1.0 mm size outweighs need for matched differential clamping. |
Compared with NUF2221MUTAG and ESD224-BI0201, PESD2CANFD27VT-QR provides superior differential bus protection via its integrated common-cathode architecture, tighter capacitance matching (±0.5%), and higher 27 V standoff - making it optimal for CAN-FD's extended voltage tolerance and timing-critical physical layer.

FAQ
What is the maximum recommended trace length between PESD2CANFD27VT-QR and the protected CAN connector?
Trace length from device pins to connector should not exceed 5 mm for each line (K1 and K2) to minimize inductance-induced voltage overshoot during ESD events. The CC (pin 3) ground connection must be routed directly to a solid ground plane using ≥2 vias within 2 mm of the pad to ensure sub-1 nH return path inductance.
Does PESD2CANFD27VT-QR protect against ISO 7637-2 load dump transients?
No - PESD2CANFD27VT-QR is rated for ESD (IEC 61000-4-2) and surge (IEC 61000-4-5, 2.5 A, 8/20 µs) only. Load dump transients (up to 120 V, 400 ms) require dedicated TVS diodes like PTVS22VS1UR with higher energy handling; this device serves as front-end ESD guard, not primary surge protection.
Can PESD2CANFD27VT-QR be used for USB 2.0 ESD protection?
No - its 27 V VRWM exceeds USB 2.0's 3.3 V signaling range, causing leakage and potential data corruption. USB 2.0 requires ≤5.5 V VRWM devices (e.g., PESD5V0S1BA). This part is purpose-built for 12 V/24 V automotive bus voltages and incompatible with low-voltage digital interfaces.
Is the 6 pF capacitance measured differentially or per channel?
The 6 pF value is measured per channel - i.e., capacitance from pin 1 to pin 3 (K1–CC) and pin 2 to pin 3 (K2–CC) - each independently specified at 5.2–6 pF (typ–max) at 1 MHz and 2.5 V reverse bias. Differential capacitance (pin 1 to pin 2) is not characterized and is not relevant to its intended application.
