Product details
Overview
VCAN33C2-03GHE3-18 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN FD and FLEX-bus interfaces. It provides ±36 V reverse stand-off voltage, <4.6 pF capacitance at 5 V, <0.05 μA leakage current, ±27 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive use.
For engineers reviewing the VCAN33C2-03GHE3-18 datasheet, VCAN33C2-03GHE3-18 pinout, VCAN33C2-03GHE3-18 application, or VCAN33C2-03GHE3-18 equivalent, key selection criteria include low-capacitance line protection for high-speed CAN FD buses, AEC-Q101 compliance, 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 diode pairs between pins 1–3 and 2–3, 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 degradation on CAN FD data lines operating up to 5 Mbps.
The VCAN33C2-03GHE3-18 features a 39–45 V breakdown voltage (at 1 mA), clamps to ≤55 V at 1 A (8/20 μs), and sustains ≤66 V at its 1.8 A peak pulse rating - meeting IEC 61000-4-5 Level 3 requirements. It is qualified per AEC-Q101 with MSL level 1 handling and operates from −55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Lines | 2 independent bidirectional channels (pins 1–3 and 2–3) |
| Reverse Stand-off Voltage | 36 V - maximum continuous working voltage before conduction begins |
| Clamping Voltage | ≤55 V at 1 A (8/20 μs) - limits transient voltage seen by downstream CAN transceiver |
| Capacitance | 3.8–4.6 pF at VR = 5 V - preserves signal edge rate and eye diagram integrity on 5 Mbps CAN FD bus |
| ESD Immunity | ±27 kV contact/air discharge (IEC 61000-4-2) - exceeds automotive OEM ESD robustness requirements |
| Leakage Current | ≤0.05 μA at 36 V - negligible DC loading on CAN bus termination resistors |
| AEC-Q101 Qualified | Yes - validated for automotive under-hood and body control module applications |
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, 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) |
| Pin 2 | Anode of Channel 2 | Connects to second protected line (e.g., CAN_L) |
| Pin 3 | Cathode (common) | Shared cathode node tied to ground or chassis reference plane |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical (BiSy) Structure | Enables identical clamping behavior for positive and negative transients on each channel - eliminates polarity concerns during layout |
| Low Capacitance Matching | ≤2% capacitance mismatch (CD13 vs CD23 at VR = 5 V) - maintains differential signal balance on CAN bus pairs |
| AEC-Q101 Qualification | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD HBM ≥8 kV - supports Tier-1 production programs |
| SOT-323 Footprint | Standardized 3-pin package with 0.65 mm pitch - enables drop-in replacement and PCB reuse across Vishay's VCANx3C2 series |
Applications
| Automotive CAN FD Bus Protection | Industrial FLEX-bus Interface |
|---|---|
Use Scenario: Protecting high-speed CAN FD communication lines (up to 5 Mbps) in engine control units, ADAS domain controllers, and battery management systems against ESD and load dump transients. IC Role / Device Role / Timing Role: Dual-line transient voltage suppressor placed between CAN transceiver and connector, providing primary board-level ESD and surge defense. Use Value: Prevents latch-up or damage to CAN transceivers during ±27 kV ESD events while maintaining signal fidelity via sub-4.6 pF line capacitance. | Use Scenario: Securing FLEX-bus signals in industrial PLC backplanes and motor drive control modules exposed to factory-floor ESD and switching noise. IC Role / Device Role / Timing Role: Bidirectional ESD clamp on differential FLEX-bus data lanes, referenced to system ground through common cathode (Pin 3). Use Value: Enables reliable operation in harsh environments with no added propagation delay or signal distortion due to symmetric low-C design. |
| Body Control Module I/O Protection | Automotive Gateway ECU Signal Conditioning |
Use Scenario: Shielding LIN/CAN mixed-signal I/O ports in door modules, seat controllers, and lighting ECUs from cable-discharge events and contact ESD. IC Role / Device Role / Timing Role: Compact dual-channel protector mounted directly at connector entry point to minimize stub length and inductance. Use Value: Reduces PCB area vs. discrete diodes and ensures consistent clamping across both lines - critical for fail-safe diagnostics. | Use Scenario: Protecting gateway ECU's multi-protocol interface (CAN FD, LIN, Ethernet PHY sidebands) where space-constrained routing demands minimal parasitic capacitance. IC Role / Device Role / Timing Role: First-stage ESD guard on CAN FD differential pair before signal conditioning and level translation stages. Use Value: Maintains >30 dB signal-to-noise ratio at 5 MHz due to matched 3.8–4.6 pF capacitance - avoids jitter accumulation in time-critical gateways. |
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 |
|---|---|---|---|
| VCAN36C2-03GHE3-18 | 36 V VRWM, 39–45 V VBR, ≤55 V VC at 1 A | Optimized for CAN FD (5 Mbps) and FLEX-bus | Default choice for new AEC-Q101-compliant CAN FD designs requiring ≤4.6 pF |
| VCAN33C2-03GHE3-08 | Identical electrical specs; differs only in packaging - 3 k per 7″ reel vs. 10 k per 13″ reel | Same functional use; suited for low-volume prototyping or small-batch builds | Select when smaller reel size aligns with assembly line feed requirements or inventory turnover targets |
Compared with VCAN36C2-03GHE3-18 and VCAN33C2-03GHE3-08, the VCAN33C2-03GHE3-18 shares identical electrical performance and AEC-Q101 qualification but offers higher volume packaging (10 k/reel), reducing cost-per-unit and feeder change frequency in high-throughput SMT lines.

FAQ
What is the maximum operating temperature range for the VCAN33C2-03GHE3-18?
The VCAN33C2-03GHE3-18 has a junction temperature range of −55 °C to +175 °C and a storage temperature range of −55 °C to +175 °C. This wide thermal envelope supports placement in under-hood automotive locations and industrial enclosures without derating, and it is validated per AEC-Q101 thermal cycling and high-temperature operating life tests.
Does the VCAN33C2-03GHE3-18 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN33C2-03GHE3-18 supports CAN FD operation up to 5 Mbps due to its ≤4.6 pF capacitance at 5 V reverse bias and matched channel capacitance (≤2% mismatch). These parameters minimize signal rise-time degradation and maintain eye opening - confirmed in Vishay's application notes for CAN FD physical layer protection.
Is the VCAN33C2-03GHE3-18 pin-compatible with other devices in the VCANx3C2 series?
Yes, all VCANx3C2-series devices - including VCAN33C2-03GHE3-18, VCAN36C2-03GHE3-18, and VCAN33C2-03GHE3-08 - share identical SOT-323 pinout (Pin 1: CH1 anode, Pin 2: CH2 anode, Pin 3: common cathode) and footprint. This allows direct substitution within the same PCB layout when adjusting VRWM or packaging.
What is the clamping voltage of the VCAN33C2-03GHE3-18 under IEC 61000-4-5 surge conditions?
The VCAN33C2-03GHE3-18 clamps to ≤54 V at its rated 1.8 A peak pulse current (8/20 μs waveform, per IEC 61000-4-5). At 1 A, clamping is ≤55 V. This ensures downstream CAN transceivers remain within safe absolute maximum ratings during surge events typical in 12 V automotive systems.
How does the VCAN33C2-03GHE3-18 differ from the VCAN36C2-03GHE3-18?
The VCAN33C2-03GHE3-18 and VCAN36C2-03GHE3-18 are electrically identical - both specify 36 V VRWM, 39–45 V VBR, ≤55 V VC at 1 A, and AEC-Q101 qualification. The "33" vs "36" in the part number reflects internal Vishay type-code differentiation, not functional variation; datasheet revision 1.1 confirms identical electrical characteristics and mechanical specifications for both.
