Vishay General Semiconductor - Diodes Division VCAN16A2-03G-E3-08

Overview

VCAN16A2-03G-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed specifically for CAN bus interfaces. It provides ±30 kV IEC 61000-4-2 contact/air discharge immunity, 16 V reverse stand-off voltage, <0.05 μA leakage current, and <18.5 pF capacitance - enabling robust transient suppression without signal integrity degradation in high-speed automotive CAN FD networks.

For engineers reviewing the VCAN16A2-03G-E3-08 datasheet, VCAN16A2-03G-E3-08 pinout, VCAN16A2-03G-E3-08 application, or VCAN16A2-03G-E3-08 equivalent, key selection criteria include its AEC-Q101 qualification, ±16 V working range, low clamping voltage (25 V @ 5 A), dual-channel symmetry, and SOT-323 footprint compatibility with space-constrained automotive PCB layouts.

Technical Context

This device implements a monolithic dual-diode array configured in a common-cathode arrangement (pins 1 & 2 anodes, pin 3 cathode), delivering matched clamping performance across both CAN_H and CAN_L lines. Its BiSy architecture ensures identical forward and reverse breakdown behavior (V_BR = 17.1–20 V), critical for maintaining differential signal integrity during ESD transients.

Thermal design is supported by a 175 °C maximum junction temperature and MSL Level 1 moisture sensitivity rating, allowing standard reflow soldering up to 260 °C peak. The e3 tin-plated terminations ensure RoHS compliance and solderability stability over time.

FAQ

What is the maximum clamping voltage of the VCAN16A2-03G-E3-08 during a 5 A ESD event?

The VCAN16A2-03G-E3-08 clamps to a maximum of 28 V at 5 A peak pulse current (8/20 µs waveform), with a typical value of 25 V. This clamping level remains consistent across both protected lines and is verified per IEC 61000-4-5 testing. The specification ensures safe operation below the absolute maximum ratings of standard CAN transceivers such as the TCAN1042 or SN65HVD230.

Is the VCAN16A2-03G-E3-08 suitable for CAN FD networks operating at 5 Mbps?

Yes, the VCAN16A2-03G-E3-08 is optimized for CAN FD. Its typical capacitance of 16.7 pF at 0 V and ≤1 pF inter-channel mismatch minimize signal distortion and timing skew, supporting bit rates up to 5 Mbps without violating ISO 11898-2 eye diagram masks. The low leakage current also prevents DC bias shift that could affect high-speed receiver thresholds.

Does the VCAN16A2-03G-E3-08 require external biasing or series resistance?

No, the VCAN16A2-03G-E3-08 operates passively with no external biasing required. It is designed for direct placement between CAN_H/CAN_L and ground, leveraging its common-cathode SOT-323 configuration. Series resistance is unnecessary because its low dynamic impedance (verified via TLP testing) ensures effective clamping without added propagation delay or signal attenuation.

What does the "E3-08" suffix indicate in VCAN16A2-03G-E3-08?

The "E3-08" suffix denotes RoHS-compliant, lead-free terminations (e3 = pure tin plating) and packaging in a 3,000-piece 7-inch reel (08 = 3K per 7″ reel). This format aligns with Vishay's standard tape-and-reel ordering code structure and supports automated SMT assembly with J-STD-020-compliant reflow profiles.

How is AEC-Q101 qualification verified for the VCAN16A2-03G-E3-08?

The VCAN16A2-03G-E3-08 is qualified per AEC-Q101 Rev. E, including H3B-class human body model testing (>8 kV), temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. Full qualification reports are available from Vishay upon request and confirm compliance for automotive under-hood and chassis-mounted applications.
