For engineers reviewing the VCAN33A2-HT5HG3-08 datasheet, VCAN33A2-HT5HG3-08 pinout, VCAN33A2-HT5HG3-08 application, or VCAN33A2-HT5HG3-08 equivalent, key selection criteria include IEC 61000-4-2 ±20 kV contact/air discharge immunity, AEC-Q101 qualification, low clamping voltage (≤52 V at 1.6 A), and matched diode capacitance (≤0.12 pF difference between lines).
Technical Context
The VCAN33A2-HT5HG3-08 implements a symmetrical dual-channel TVS architecture with common cathode configuration (pin 3 as shared cathode), enabling simultaneous bidirectional transient suppression on two independent CAN FD signal lines. Its design targets high-speed data integrity under ESD stress while maintaining sub-6 pF load capacitance to avoid signal distortion.
It meets AEC-Q101 stress requirements including HBM Class H3B (>8 kV), operates from −55 °C to +150 °C junction temperature, and features e3 tin-plated terminations compatible with automated optical inspection (AOI) and lead-free reflow soldering up to 260 °C peak.

FAQ
What is the maximum operating temperature range for the VCAN33A2-HT5HG3-08?
The VCAN33A2-HT5HG3-08 has a specified junction temperature range of −55 °C to +150 °C and storage temperature range of −55 °C to +150 °C. This wide range supports deployment in under-hood automotive environments, industrial motor drives, and EV battery enclosures where thermal extremes are common. The device maintains full ESD immunity and clamping performance across this entire range per AEC-Q101 test conditions.
Does the VCAN33A2-HT5HG3-08 support bidirectional signal integrity on both protected lines?
Yes, the VCAN33A2-HT5HG3-08 uses a bidirectional symmetrical (BiSy) architecture with matched diodes per line, ensuring identical clamping behavior for positive and negative transients on both Line 1 (Pin 1–Pin 3) and Line 2 (Pin 2–Pin 3). Its ≤0.12 pF capacitance mismatch guarantees balanced differential timing - essential for maintaining CAN FD signal fidelity at 5 Mbps.
Is the VCAN33A2-HT5HG3-08 pin-compatible with other Vishay VCAN-series diodes?
No - the VCAN33A2-HT5HG3-08 uses the DFN1110-3A package with a unique 3-pin common-cathode layout. Other VCAN variants (e.g., VCAN5V0A2 or VCAN12A2) use different packages (SOT-23, SC-70) or pin counts. Direct substitution requires PCB layout revision; always verify package dimensions and pin function mapping before replacement.
What is the meaning of "HT5" in the VCAN33A2-HT5HG3-08 part number?
The "HT5" suffix in VCAN33A2-HT5HG3-08 denotes the device's high-temperature grade and tape-and-reel packaging variant: "HT" indicates extended junction temperature capability (−55 °C to +150 °C), and "5" specifies the DFN1110-3A package. This distinguishes it from standard-temperature versions and confirms full AEC-Q101 qualification per Vishay document 86544.
Can the VCAN33A2-HT5HG3-08 be used for non-CAN protocols like LIN or SENT?
No - the VCAN33A2-HT5HG3-08 is specifically characterized and qualified for CAN FD applications, with 33 V standoff and clamping optimized for CAN bus voltage margins. For LIN (12 V max) or SENT (40 V max) interfaces, Vishay recommends dedicated parts such as VBUS05M2-HT or VESDxxA2 series, which offer appropriate voltage ratings and lower capacitance where needed.
