Product details
Overview
VCAN26C2-03GHE3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN FD and FLEX-bus interfaces. It provides ±26.5 V reverse stand-off voltage, <6 pF capacitance at 5 V, <0.05 μA leakage current, ±30 kV IEC 61000-4-2 contact/air discharge immunity, and AEC-Q101 qualification for automotive-grade robustness.
For engineers reviewing the VCAN26C2-03GHE3-08 datasheet, VCAN26C2-03GHE3-08 pinout, VCAN26C2-03GHE3-08 application, or VCAN26C2-03GHE3-08 equivalent, this page delivers verified electrical parameters, terminal mapping, automotive interface compatibility, low-capacitance signal integrity impact, and qualified alternatives for CAN bus transient suppression design.
Technical Context
This device implements a symmetrical dual-channel TVS architecture with matched clamping characteristics across both protected lines (pins 1–3 and 2–3), enabling balanced ESD protection without polarity sensitivity. Its BiSy topology ensures identical forward/reverse breakdown behavior, critical for differential bus protocols like CAN FD where signal symmetry preserves common-mode rejection.
Designed specifically for high-speed serial buses, it maintains sub-6 pF load capacitance at 5 V bias to minimize signal distortion on 5 Mbps+ CAN FD links. The 37 V typical clamping voltage at 1 A (8/20 μs) and 45 V max at 2.5 A limits transients while preserving receiver input thresholds under IEC 61000-4-5 surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - Maximum continuous operating voltage before conduction; sets upper limit for CAN FD bus DC bias tolerance |
| Clamping Voltage (1 A) | 34–37 V - Peak voltage seen by protected IC during 1 A ESD pulse; ensures CAN transceiver I/O remains within safe SOA |
| Capacitance (5 V) | 5–6 pF - Low line loading enables >5 Mbps CAN FD data rates without signal rise-time degradation |
| ESD Immunity | ±30 kV contact/air - Meets IEC 61000-4-2 Level 4, exceeding automotive OEM requirements for infotainment and body control modules |
| Leakage Current | <0.05 μA - Negligible DC power loss and bus loading at full temperature range (−55 °C to +175 °C) |

| Pin 3 | Cathode (Common) | Shared cathode node tied to ground or local reference; enables dual-line protection with single return path |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical (BiSy) Clamping | Identical VBR (28–32 V) and VC performance for both polarities - eliminates need for polarity-aware layout on differential buses |
| Dual-Line Protection in Single Package | Two independent ESD paths (1–3 and 2–3) with ≤2% capacitance matching - preserves differential signal integrity on CAN FD pairs |
| Low Capacitance at Operating Bias | 5 pF typical at 5 V reverse bias - reduces insertion loss and jitter on 5–8 Mbps CAN FD physical layer |
| AEC-Q101 Qualification | Validated for automotive underhood environments (−55 °C to +175 °C junction) - supports direct integration into ECUs without derating |
Applications

IC Role / Device Role / Timing Role: High-speed capacitive filter suppressing ESD energy before it couples onto internal CAN routing traces. Use Value: Reduces system-level failure rate in EMC testing by limiting coupled transients to <37 V peak at 1 A, well below transceiver absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Lower VRWM (5.5 V), higher CD (12 pF at 0 V), same SOT-323 package | Targeted at 3.3 V/5 V digital I/O, not rated for 26.5 V CAN bus operation | Select only for low-voltage logic-level protection; unsuitable for direct CAN FD line placement |
| LITTELFUSE SP1003-01WTG | Unidirectional configuration, 12 V VRWM, 0.5 pF CD, SOD-323 package | Optimized for ultra-high-speed USB 3.0/PCIe, lacks symmetrical clamping for differential buses | Use where minimal capacitance is critical and polarity is controlled; not a functional substitute for BiSy CAN protection |
Compared with RCLAMP0524P.TCT and SP1003-01WTG, VCAN26C2-03GHE3-08 uniquely combines 26.5 V working voltage, BiSy symmetry, and sub-6 pF loading-making it the only qualified option for drop-in replacement in AEC-Q101-compliant CAN FD node designs requiring dual-line transient suppression without signal imbalance.

FAQ
What is the maximum operating voltage supported by VCAN26C2-03GHE3-08?
The VCAN26C2-03GHE3-08 supports a maximum reverse stand-off voltage (VRWM) of 26.5 V, meaning it can continuously withstand up to ±26.5 V DC or steady-state AC signals without clamping. This aligns precisely with the peak differential voltage range of CAN FD physical layers and ensures reliable operation without false triggering during normal bus activity.
Is VCAN26C2-03GHE3-08 qualified for automotive underhood applications?
Yes, VCAN26C2-03GHE3-08 is AEC-Q101 qualified and rated for junction temperatures from −55 °C to +175 °C. Its qualification includes human body model (HBM) testing >8 kV (Class H3B), making it suitable for underhood ECUs, transmission control modules, and other high-temperature automotive environments where reliability under thermal and electrical stress is mandatory.
How does the bidirectional symmetrical (BiSy) architecture benefit CAN FD implementation?
The BiSy architecture of VCAN26C2-03GHE3-08 ensures identical clamping voltage and breakdown behavior in both polarities across each protected line. This eliminates signal asymmetry on differential CAN FD pairs, preserving common-mode noise rejection and preventing duty-cycle distortion that could occur with unidirectional or mismatched diodes-critical for maintaining bit error rate (BER) at 5+ Mbps data rates.
What is the typical capacitance of VCAN26C2-03GHE3-08 at 5 V reverse bias?
The typical capacitance of VCAN26C2-03GHE3-08 is 5 pF at 5 V reverse bias and 1 MHz frequency. This low value minimizes high-frequency signal attenuation and ensures rise/fall time integrity on CAN FD buses operating up to 8 Mbps, directly supporting ISO 11898-2 timing budgets without requiring layout compensation.
Can VCAN26C2-03GHE3-08 be used for FLEX-bus protection?
Yes, VCAN26C2-03GHE3-08 is explicitly specified for FLEX-bus applications in its Vishay datasheet. Its 26.5 V VRWM, matched dual-channel capacitance (<2% mismatch), and ±30 kV ESD immunity meet the electrical and reliability requirements of FLEX-bus physical layer implementations in industrial motion control and modular I/O systems.
