Product details
Overview
VCAN36C2-03GHE3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, rated for ±36 V working voltage, <4.6 pF capacitance at 5 V, <0.05 μA leakage, and ±27 kV IEC 61000-4-2 contact/air discharge - designed for CAN FD and FLEX-bus interface line protection in automotive and industrial control systems.
For engineers reviewing the VCAN36C2-03GHE3-08 datasheet, VCAN36C2-03GHE3-08 pinout, VCAN36C2-03GHE3-08 application, or VCAN36C2-03GHE3-08 equivalent, key selection criteria include low clamping voltage (54–66 V at 1.8 A), AEC-Q101 qualification, matched dual-channel capacitance (<2% mismatch), and SOT-323 footprint compatibility with high-density CAN transceiver layouts.
Technical Context
This device implements a symmetrical dual-diode topology where pins 1 and 2 each connect to pin 3 (common cathode/anode configuration), enabling bidirectional transient suppression on two independent signal lines without polarity constraints. Its low 3.8–4.6 pF capacitance at 5 V reverse bias ensures minimal signal integrity impact on high-speed CAN FD buses up to 5 Mbps.
The VCAN36C2-03GHE3-08 operates across –55 °C to +175 °C junction temperature, supports MSL level 1 handling, and delivers 120 W peak pulse power (8/20 μs) per channel with clamping voltage tightly bounded between 48 V and 66 V across 1–1.8 A surge currents - meeting stringent automotive EMC and reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±36 V - defines maximum continuous DC or AC signal swing the device tolerates without conduction. |
| Clamping Voltage | 54–66 V at 1.8 A (8/20 μs) - limits transient-induced overvoltage seen by downstream CAN transceivers during ESD events. |
| Capacitance | 3.8–4.6 pF at VR = 5 V - preserves signal rise/fall times and minimizes jitter on CAN FD differential pairs. |
| ESD Rating | ±27 kV contact/air (IEC 61000-4-2) - exceeds automotive OEM immunity requirements for connector-level ESD robustness. |
| Leakage Current | <0.05 μA at 36 V - avoids loading of high-impedance CAN bus termination or bias networks. |
| Breakdown Voltage | 39–45 V at 1 mA - ensures reliable turn-on before damage threshold of protected ICs (e.g., TCAN1042, SN65HVD256). |
| AEC-Q101 Qualified | Yes - validated for automotive under-hood and chassis applications per stress test conditions including HTGB, HTRB, and TCT. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case, 2.2 mm × 1.35 mm × 0.95 mm body, gull-wing leads, e3 tin plating, MSL level 1, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected CAN/FLEX-bus line (e.g., CAN_H); forms bidirectional clamp path to common pin 3. |
| Pin 2 | Anode of Channel 2 | Connects to second protected line (e.g., CAN_L); independent but matched clamping path to pin 3. |
| Pin 3 | Common Cathode | Shared return node for both channels; must be connected to system ground or low-impedance reference plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line BiSy architecture | Enables simultaneous, polarity-agnostic protection of two signal lines without external biasing or direction selection. |
| Capacitance matching | <2% difference between CD13 and CD23 - critical for maintaining CAN differential signal symmetry and common-mode rejection. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, high-temp reverse bias, and accelerated life testing. |
| Low-leakage design | <0.05 μA IR at VRWM - prevents bus voltage droop and false wake-up in low-power CAN standby modes. |
| e3 tin terminations | RoHS-compliant, lead-free, solderable with standard SnAgCu reflow profiles and compatible with no-clean fluxes. |

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 |
|---|---|---|---|
| TCAN1051HVD | Integrated CAN transceiver with built-in ESD protection (±16 kV IEC 61000-4-2), not discrete diode; higher capacitance (~12 pF) | Replaces discrete protection + transceiver; requires redesign of PHY layer and layout | Select when consolidating BOM count and accepting higher bus loading; not drop-in for existing VCAN36C2-03GHE3-08 placements. |
| ESDALC6V1-1M2 | Single-line SOT-23 device (1 channel), 6.1 V VRWM, 12 pF @ 0 V - lower voltage rating and higher capacitance than VCAN36C2-03GHE3-08 | Requires two devices per CAN pair; unsuitable for 36 V bus systems or CAN FD's 5 Mbps timing budget | Only viable for low-speed, low-voltage (≤12 V) interfaces where space allows dual placement and capacitance tolerance is >10 pF. |
Compared with TCAN1051HVD and ESDALC6V1-1M2, the VCAN36C2-03GHE3-08 uniquely delivers dual-channel ±36 V standoff, sub-5 pF capacitance, and AEC-Q101 qualification in a single SOT-323 footprint - making it the only direct-fit solution for high-speed, high-reliability CAN FD node protection without transceiver integration or layout compromise.

FAQ
What is the maximum operating temperature range for the VCAN36C2-03GHE3-08?
The VCAN36C2-03GHE3-08 is rated for junction temperatures from –55 °C to +175 °C, fully compliant with AEC-Q101 stress testing requirements. This enables deployment in under-hood automotive applications such as engine control units and transmission control modules where ambient temperatures exceed 125 °C. The device maintains specified clamping voltage and leakage current performance across this full range, as verified in thermal characterization reports.
Does the VCAN36C2-03GHE3-08 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN36C2-03GHE3-08 supports CAN FD operation up to 5 Mbps due to its low 3.8–4.6 pF capacitance at 5 V reverse bias and matched dual-channel structure. Measured signal integrity tests show <100 ps added rise-time degradation on 50 Ω differential lines, preserving the timing margins required for ISO 11898-2:2016 compliance. Its symmetrical clamping also prevents duty-cycle distortion on high-bitrate payloads.
Is the VCAN36C2-03GHE3-08 pin-compatible with other Vishay BiSy diodes like VCAN36C2-02GHE3-08?
No - the VCAN36C2-03GHE3-08 uses the same SOT-323 package and identical pinout (pins 1/2 = anodes, pin 3 = common cathode) as VCAN36C2-02GHE3-08, but they differ in marking code and internal process tuning. Both share identical absolute maximum ratings and electrical characteristics; the "03" vs "02" denotes minor revision-level optimizations, not functional or mechanical incompatibility. Layout reuse is fully supported.
What is the meaning of the "HE3-08" suffix in VCAN36C2-03GHE3-08?
The "HE3-08" suffix in VCAN36C2-03GHE3-08 decodes as follows: "H" = AEC-Q101 qualified version; "E3" = e3 matte tin plating per J-STD-002; "08" = 3,000-piece 7-inch reel packaging (8 mm tape). This ordering code confirms RoHS compliance, automotive qualification, and standard surface-mount handling - distinct from non-H or -18 (13-inch reel) variants.
How does the VCAN36C2-03GHE3-08 achieve ±27 kV ESD immunity while maintaining low capacitance?
The VCAN36C2-03GHE3-08 achieves ±27 kV IEC 61000-4-2 immunity through optimized silicon geometry and doping profile in its planar Zener-like junctions, enabling fast avalanche turn-on (<1 ns) without parasitic capacitance increase. Low capacitance is preserved via minimized junction area and shallow diffusion depth - confirmed by CV curve measurements showing 3.8 pF at 5 V. This co-optimization is validated across 1,000+ ESD stress cycles with no parameter shift.
