Vishay General Semiconductor - Diodes Division VCAN36C2-03G-E3-08

Overview

VCAN36C2-03G-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, rated for ±36 V working voltage, <4.6 pF capacitance at 5 V, <0.05 μA leakage, and ±27 kV IEC 61000-4-2 contact/air discharge immunity - deployed in CAN FD and FLEX-bus automotive communication interfaces.

For engineers reviewing the VCAN36C2-03G-E3-08 datasheet, VCAN36C2-03G-E3-08 pinout, VCAN36C2-03G-E3-08 application, or VCAN36C2-03G-E3-08 equivalent, key selection criteria include low-load capacitance for high-speed bus integrity, AEC-Q101 qualification for under-hood reliability, and dual-channel symmetric clamping for bidirectional signal line protection.

Technical Context

This device implements two independent, matched, bidirectional TVS diodes in a single SOT-323 package, each protecting one signal line (Pin 1–3 and Pin 2–3) with symmetrical breakdown at 39–45 V and clamping ≤55 V at 1 A (8/20 μs). It meets IEC 61000-4-2 (±27 kV) and AEC-Q101 H3B (>8 kV HBM) requirements.

Designed specifically for CAN FD (up to 5 Mbps) and FLEX-bus physical layers, its <4.6 pF capacitance at VR = 5 V minimizes signal distortion, while its MSL Level 1 rating and tin-plated e3 terminations support lead-free reflow up to 260 °C without moisture sensitivity concerns.

FAQ

What is the maximum clamping voltage of the VCAN36C2-03G-E3-08 at 1.8 A peak pulse current?

The VCAN36C2-03G-E3-08 exhibits a maximum clamping voltage of 66 V at IPPM = 1.8 A (8/20 μs waveform), as specified in the Absolute Maximum Ratings table. This value ensures safe operation within the absolute maximum input voltage limits of most CAN FD transceivers, including those rated to 70 V. The clamping performance is verified per IEC 61000-4-5 test conditions and remains stable across the full -55 °C to +175 °C junction temperature range.

Is the VCAN36C2-03G-E3-08 pin-compatible with other dual-line ESD diodes in SOT-323?

The VCAN36C2-03G-E3-08 uses a standard SOT-323 pinout (Pin 1: CH1, Pin 2: CH2, Pin 3: common), matching industry-standard dual-channel TVS footprints. However, pin compatibility alone does not guarantee functional equivalence - for example, RCLAMP0524P.TCT shares the package but has only 5.5 V VRWM and cannot withstand 36 V bus operation. Always verify electrical parameters and qualification status before substitution.

Does the VCAN36C2-03G-E3-08 support CAN FD data rates up to 5 Mbps?

Yes, the VCAN36C2-03G-E3-08 supports CAN FD operation up to 5 Mbps due to its guaranteed capacitance of ≤4.6 pF at 5 V reverse bias and matched channel capacitance (dCD ≤ 2 %), which minimizes signal distortion, timing skew, and reflections on differential pairs. Its low leakage (<0.05 μA) also prevents DC loading that could affect bus biasing at high bit rates.

What does the "E3-08" suffix indicate in VCAN36C2-03G-E3-08?

The "E3-08" suffix in VCAN36C2-03G-E3-08 denotes RoHS-compliant, lead-free terminations (e3 = pure tin plating) and packaging: "08" specifies 3,000 units per 7-inch reel on 8 mm carrier tape. This packaging format is optimized for high-volume SMT assembly and aligns with Vishay's standard logistics coding for automotive-grade components.

How is the VCAN36C2-03G-E3-08 qualified for automotive use beyond AEC-Q101?

The VCAN36C2-03G-E3-08 is AEC-Q101 qualified per H3B human body model (>8 kV), and its construction - including UL 94 V-0 molding compound, MSL Level 1 moisture rating, and 260 °C peak reflow tolerance - satisfies additional automotive process requirements. While not individually PPAP-certified, it is widely adopted in Tier-1 designs for powertrain and body control modules where full AEC-Q100 MCU-level qualification is not required for discrete protectors.
