Product details
Overview
VCAN26A2-03GHE3-18 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, rated for ±26.5 V reverse stand-off voltage, <0.05 μA leakage current at VRWM, <13 pF load capacitance, and ±30 kV IEC 61000-4-2 contact/air discharge immunity - deployed in automotive CAN bus interfaces to suppress transient surges while preserving signal integrity.
For engineers reviewing the VCAN26A2-03GHE3-18 datasheet, VCAN26A2-03GHE3-18 pinout, VCAN26A2-03GHE3-18 application, or VCAN26A2-03GHE3-18 equivalent, key selection criteria include bidirectional clamping performance at 3 A peak pulse current, AEC-Q101 qualification status, SOT-323 footprint compatibility, and sub-13 pF capacitance for high-speed CAN FD signal paths.
Technical Context
This device implements two independent, matched ESD protection paths (pin 1–3 and pin 2–3) with symmetrical clamping behavior, enabling robust bidirectional transient suppression on differential CAN H/L lines without polarity constraints. Its low capacitance matching (<1.5 pF difference between channels) ensures balanced signal propagation delay across both lines.
The junction temperature rating of −55 °C to +175 °C and MSL Level 1 soldering profile (peak 260 °C) support under-hood automotive deployment. It meets IEC 61000-4-2 (±30 kV), ISO 10605 (±30 kV), and AEC-Q101 Class H3B (>8 kV HBM) requirements - confirming suitability for harsh-environment vehicle networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - maximum continuous working voltage before clamping onset; sets upper limit for CAN bus DC bias tolerance |
| Peak Pulse Current (8/20 μs) | 3 A - withstands IEC 61000-4-5 surge events without failure; defines transient energy handling capacity |
| Clamping Voltage @ 1 A | 33–40 V - voltage seen by protected IC during 1 A transient; critical for ensuring downstream CAN transceiver survival |
| Diode Capacitance @ 0 V | 10–13 pF - low loading on high-speed CAN FD signals (up to 5 Mbps); minimizes rise-time degradation |
| Capacitance Matching | ≤1.5 pF difference between channels - maintains differential signal symmetry and common-mode rejection |
| ESD Immunity | ±30 kV contact/air per IEC 61000-4-2 - exceeds automotive OEM ESD test requirements for connector-level surges |
| Junction Temperature Range | −55 °C to +175 °C - supports placement near engine control units or powertrain modules |
