Product details
Overview
VCAN36A2-03G-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, <0.05 μA reverse leakage, <10 pF capacitance, and ±30 kV IEC 61000-4-2 contact/air discharge immunity - deployed on CAN bus transceiver interfaces in automotive control modules.
For engineers reviewing the VCAN36A2-03G-E3-08 datasheet, VCAN36A2-03G-E3-08 pinout, VCAN36A2-03G-E3-08 application, or VCAN36A2-03G-E3-08 equivalent, key selection criteria include low-capacitance dual-line protection, AEC-Q101 qualification, SOT-323 footprint compatibility, and clamping performance under 8/20 μs surge conditions.
Technical Context
This device implements a symmetrical dual-channel TVS structure with matched breakdown thresholds (39–45 V), enabling bidirectional transient suppression across two independent signal lines referenced to common ground. Its low 8–10 pF capacitance at 0 V ensures minimal signal integrity impact on high-speed CAN FD (up to 5 Mbps) and FlexRay interfaces.
The VCAN36A2-03G-E3-08 delivers 55–63 V clamping voltage at 2.4 A peak pulse current (IEC 61000-4-5, 8/20 μs), with junction temperature range of −55 °C to +175 °C and MSL level 1 moisture sensitivity - confirming suitability for under-hood automotive environments and reflow-soldered PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Lines | 2 independent bidirectional channels - supports dual-signal CAN H/L or FlexRay A/B protection without external biasing |
| Reverse Stand-off Voltage | 36 V - sets maximum continuous operating voltage before conduction begins; matches standard 24 V automotive supply rails with margin |
| Clamping Voltage (2.4 A) | 55–63 V - limits transient overvoltage seen by downstream CAN transceiver ICs during 8/20 μs surges |
| Capacitance (0 V, 1 MHz) | 8–10 pF - preserves signal edge rate and eye diagram integrity on 5 Mbps CAN FD buses |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements for exterior harness interfaces |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HBM >8 kV (Class H3B) and temperature cycling |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case, 2.2 mm × 1.35 mm × 0.95 mm body, e3 tin-plated terminations, MSL level 1, peak reflow temperature 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected line (e.g., CAN_H); forms symmetrical clamp path with Pin 3 |
| Pin 2 | Anode of Channel 2 | Connects to second protected line (e.g., CAN_L); independent but matched clamping behavior vs. Pin 3 |
| Pin 3 | Cathode (Common Ground Reference) | Shared cathode node tied to system ground; enables compact dual-line layout with single ground return |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical Clamping | Matched 39–45 V breakdown on both polarities per channel - eliminates need for polarity-aware layout or external bias networks |
| Low Capacitance (8–10 pF) | Minimizes signal distortion and timing skew on differential CAN/FlexRay pairs operating up to 5 Mbps |
| AEC-Q101 Qualification | Validated for automotive under-hood use including temperature cycling, mechanical shock, and humidity testing |
| e3 Tin Plating | Lead (Pb)-free, RoHS-compliant terminations compatible with standard SnAgCu reflow profiles |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Lower VRWM (5 V), higher capacitance (15 pF), same SOT-323 package | Targeted for USB/low-voltage logic; unsuitable for 24 V CAN bus due to premature conduction | Select only for 3.3 V/5 V digital interfaces - not a drop-in replacement for VCAN36A2-03G-E3-08 |
| LITTELFUSE SP1003-03HTG | Same 36 V VRWM, 12 pF capacitance, AEC-Q101 qualified, SOT-23-3 package | SOT-23 footprint differs (larger pad pitch, different thermal pad); requires PCB redesign | Valid alternative if board layout allows SOT-23 adaptation and 12 pF loading is acceptable |
Compared with RCLAMP0524P.TCT and SP1003-03HTG, the VCAN36A2-03G-E3-08 uniquely combines 36 V stand-off, ≤10 pF capacitance, SOT-323 size, and AEC-Q101 qualification - making it the only option meeting all four criteria for space-constrained automotive CAN designs.

FAQ
What is the maximum continuous operating voltage for VCAN36A2-03G-E3-08?
The VCAN36A2-03G-E3-08 has a reverse stand-off voltage (VRWM) of 36 V, meaning it remains non-conductive up to this DC or RMS voltage level under normal operation. This rating aligns with 24 V automotive systems plus safety margin and is verified per IEC 61000-4-2 test conditions at 25 °C ambient.
Does VCAN36A2-03G-E3-08 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN36A2-03G-E3-08 supports CAN FD operation up to 5 Mbps due to its low 8–10 pF capacitance at 0 V and symmetrical clamping architecture, which minimizes signal rise-time degradation and jitter. Measured performance confirms no eye-diagram closure beyond specification limits on standard 120 Ω differential CAN bus traces.
Is VCAN36A2-03G-E3-08 qualified to AEC-Q101 standards?
Yes, VCAN36A2-03G-E3-08 is fully AEC-Q101 qualified, including human body model (HBM) Class H3B (>8 kV), temperature cycling, and high-temperature operating life testing. The "H" in the ordering code (e.g., VCAN36A2-03GHE3A08) explicitly denotes AEC-Q101 qualification per Vishay's documentation.
What is the clamping voltage of VCAN36A2-03G-E3-08 at 1 A and 2.4 A peak pulse current?
Per the datasheet, the VCAN36A2-03G-E3-08 clamps to 48–54 V at 1 A (8/20 μs waveform) and 55–63 V at its rated 2.4 A peak pulse current. These values are measured pin-to-ground (Pin 1 or 2 to Pin 3) and define the maximum voltage imposed on protected circuitry during surge events.
Can VCAN36A2-03G-E3-08 be used for FlexRay bus protection?
Yes, VCAN36A2-03G-E3-08 is explicitly rated for FlexRay applications per Vishay's features list and electrical specifications. Its 36 V stand-off, low capacitance, and bidirectional symmetry match FlexRay's 2.5 V differential swing and 10 Mbps data rate requirements while surviving ISO 16750-2 power supply transients.
