Product details
Overview
VCAN36A2-03GHE3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, rated for ±36 V working voltage, <0.05 μA reverse leakage, <10 pF load capacitance, and ±30 kV IEC 61000-4-2 contact/air discharge immunity - designed specifically for CAN bus and FLEX-bus interface protection.
For engineers reviewing the VCAN36A2-03GHE3-08 datasheet, VCAN36A2-03GHE3-08 pinout, VCAN36A2-03GHE3-08 application, or VCAN36A2-03GHE3-08 equivalent, key selection criteria include bidirectional clamping symmetry, low capacitance for high-speed signal integrity, AEC-Q101 qualification, SOT-323 footprint compatibility, and robust 150 W peak pulse power handling per line.
Technical Context
This device implements a dual-channel, symmetrical TVS structure with matched forward/reverse breakdown characteristics (VBR = 39–45 V), enabling identical clamping behavior on both signal polarities - critical for differential bus protocols like CAN. Each channel protects one data line (e.g., CAN_H/CAN_L) referenced to ground (pin 3).
It operates within -55 °C to +175 °C junction temperature range and meets AEC-Q101 stress requirements including HBM Class H3B (>8 kV), supporting automotive-grade reliability. The e3 tin-plated terminations and MSL Level 1 soldering profile ensure compatibility with standard reflow processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line TVS - enables identical clamping on both signal polarities for differential bus protection |
| Working Voltage | ±36 V reverse stand-off (VRWM) - supports full CAN transceiver common-mode range without leakage-induced bias shift |
| Clamping Voltage | ≤54 V at 1 A (8/20 μs); ≤63 V at 2.4 A - limits transient overvoltage to safe levels for downstream CAN PHY ICs |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode/Cathode (BiSy) | Input/output terminal for first protected signal line (e.g., CAN_H); bidirectional conduction path to Pin 3 |
| Pin 2 | Line 2 Anode/Cathode (BiSy) | Input/output terminal for second protected signal line (e.g., CAN_L); independent bidirectional path to Pin 3 |
| Pin 3 | Common Cathode/Anode Reference | Shared ground reference node for both protection channels; must be connected to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetry | Matched VBR (39–45 V) and VC across both polarities ensures equal clamping on CAN_H/CAN_L during fast transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Lower VRWM (5 V), higher CD (15 pF), same SOT-323 package | Targeted at USB/low-voltage logic; unsuitable for 36 V CAN bus due to premature conduction | Select only for sub-12 V interfaces where lower clamping voltage is prioritized over voltage range |
| LITTELFUSE SP3022-01UTG | Single-line device (1-channel), same VRWM/CD, SOD-323 package | Requires two devices for dual-line protection; larger total footprint than VCAN36A2-03GHE3-08's integrated dual-channel design | Use when board layout allows discrete placement or when channel isolation beyond shared cathode is required |
Compared with RCLAMP0524P.TCT and SP3022-01UTG, VCAN36A2-03GHE3-08 uniquely delivers integrated dual-line ±36 V protection in a single SOT-323, minimizing PCB area and ensuring matched clamping response - essential for differential bus signal integrity and automotive qualification compliance.

FAQ
What is the maximum clamping voltage of the VCAN36A2-03GHE3-08 at 2.4 A peak pulse current?
The VCAN36A2-03GHE3-08 exhibits a maximum clamping voltage of 63 V at 2.4 A peak pulse current (8/20 μs waveform), as specified in its electrical characteristics table. This value ensures downstream CAN transceivers remain within safe operating voltage limits during severe surge events. The clamping performance is verified per IEC 61000-4-5 test conditions and applies to each protected line referenced to pin 3. VCAN36A2-03GHE3-08 maintains this specification across its full operating temperature range.
Is the VCAN36A2-03GHE3-08 qualified for automotive applications?
Yes, the VCAN36A2-03GHE3-08 is AEC-Q101 qualified, specifically meeting HBM Class H3B (>8 kV) requirements. It is rated for junction temperatures from -55 °C to +175 °C and features MSL Level 1 moisture sensitivity and e3 tin-plated terminations - all aligned with automotive production standards. VCAN36A2-03GHE3-08 is widely deployed in engine control units, battery management systems, and ADAS modules where reliability under thermal and electrical stress is critical.
How many signal lines does the VCAN36A2-03GHE3-08 protect simultaneously?
The VCAN36A2-03GHE3-08 protects two independent signal lines simultaneously - one connected between pin 1 and pin 3, the other between pin 2 and pin 3. Its dual-channel BiSy architecture provides matched bidirectional clamping for differential bus protocols such as CAN and FLEX-bus. VCAN36A2-03GHE3-08 does not support three-line or single-ended configurations; pin 3 serves exclusively as the common reference node for both channels.
What is the typical capacitance of the VCAN36A2-03GHE3-08 at 0 V reverse bias?
The typical capacitance of the VCAN36A2-03GHE3-08 is 8 pF at 0 V reverse bias and 1 MHz, with a maximum of 10 pF. This low load capacitance is measured across each protection path (pin 1–3 and pin 2–3) and is critical for preserving signal edge integrity on high-speed CAN FD buses operating up to 5 Mbps. VCAN36A2-03GHE3-08 maintains this capacitance stability across its operating voltage range, as confirmed by Figure 4 in the official Vishay datasheet.
Does the VCAN36A2-03GHE3-08 require external biasing or control signals?
No, the VCAN36A2-03GHE3-08 is a passive, unidirectional/bidirectional TVS diode array requiring no external biasing, power supply, or control signals. It operates purely on voltage-dependent avalanche conduction - clamping transients automatically when line-to-ground voltage exceeds ±36 V. VCAN36A2-03GHE3-08 functions immediately upon installation with only proper grounding of pin 3, making it ideal for space-constrained, low-complexity protection schemes.
