Product details
Overview
VCAN33A2-03G-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN-bus interface protection. It delivers ±33 V reverse stand-off voltage, <0.05 μA leakage current at 33 V, <9.7 pF capacitance per line, ±30 kV IEC 61000-4-2 contact/air discharge immunity, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the VCAN33A2-03G-E3-08 datasheet, VCAN33A2-03G-E3-08 pinout, VCAN33A2-03G-E3-08 application, or VCAN33A2-03G-E3-08 equivalent, this device supports high-reliability CAN FD and classical CAN transceivers requiring low-capacitance, high-temperature (TJ up to 175 °C), and robust transient suppression in space-constrained layouts.
Technical Context
The VCAN33A2-03G-E3-08 integrates two matched, symmetrical TVS diodes in a single SOT-323 package, enabling simultaneous protection of CAN_H and CAN_L lines without polarity sensitivity. Its BiSy architecture ensures identical clamping behavior in both directions, with tight capacitance matching (<1 pF difference between channels) critical for signal integrity on differential buses.
It operates across –55 °C to +175 °C junction temperature, supports peak pulse power of 140 W (8/20 μs), and achieves clamping voltage ≤56 V at 2.5 A peak pulse current - meeting stringent requirements for automotive infotainment, body control modules, and ADAS sensor interfaces where ESD robustness and minimal signal distortion are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line TVS - enables polarity-agnostic placement on differential CAN bus pairs |
| Reverse Stand-off Voltage (VRWM) | 33 V - matches nominal CAN bus common-mode range while avoiding false triggering during normal operation |
| Clamping Voltage (VC) | ≤56 V at 2.5 A (8/20 μs) - limits transients below CAN transceiver absolute maximum ratings (typically 60–70 V) |
| Capacitance per Line (CD) | 8.7–9.7 pF at 0 V, 1 MHz - preserves signal edge rate and minimizes jitter on CAN FD (up to 5 Mbps) links |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements (e.g., GMW3172, Ford ES-XW7T-1A278-AC) |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HBM >8 kV and high-temperature operating life |

| Pin 3 | Cathode (Common Rail) | Shared cathode tied to ground or chassis; enables compact dual-line layout with single return path |
Key Features
| Feature | Design Value |
|---|---|
| BiSy architecture | Identical forward/reverse breakdown (36–40 V) and clamping behavior on both lines - eliminates need for orientation-aware layout |
| Low capacitance matching | ≤1 pF difference between CD13 and CD23 - maintains <0.1% skew on differential signals up to 5 Mbps |
| High-temperature operation | TJ max = 175 °C - supports under-hood deployment without derating in engine control units or battery management systems |
| e3 tin plating | RoHS-compliant Sn termination - ensures solderability and intermetallic compatibility with lead-free reflow profiles |

Applications
| Automotive CAN FD Networks | Industrial CAN Bus Nodes |
|---|---|
Use Scenario: High-speed CAN FD communication (2–5 Mbps) between ADAS camera ECUs and domain controllers in ambient temperatures up to 125 °C. IC Role / Device Role / Timing Role: Dual-line ESD suppressor placed directly at connector interface, before CAN transceiver input pins. Use Value: Prevents latch-up or damage to TI TCAN1042 or NXP TJA1044 transceivers during ISO 10605 ESD testing while preserving signal rise time (<1 ns degradation). |
Use Scenario: CAN-based PLC I/O modules operating in factory automation environments with frequent electrostatic discharges near metal enclosures. IC Role / Device Role / Timing Role: Board-level ESD guard for isolated CAN transceivers (e.g., Analog Devices ADM3053) in DIN-rail mounted controllers. Use Value: Maintains <10 pF loading on both bus lines to avoid bit error rate increase at 1 Mbps, while surviving repeated ±30 kV contact discharges without parameter drift. |
| Body Control Modules (BCM) | Electric Power Steering (EPS) Sensors |
Use Scenario: Door module integration with LIN/CAN gateway handling mirror, lock, and lighting functions in humid, vibration-prone cabin environments. IC Role / Device Role / Timing Role: Secondary ESD protection stage after connector-level ferrite beads, co-located with CAN transceiver. Use Value: Enables MSL-1 handling and 260 °C reflow compatibility - supports high-yield manufacturing of multi-layer BCM PCBs with tight thermal budgets. |
Use Scenario: Torque and angle sensor signals routed over CAN to EPS motor controller in proximity to high-current motor drivers. IC Role / Device Role / Timing Role: Transient voltage suppressor placed at sensor harness entry point to shield analog front-end and CAN PHY from coupled noise. Use Value: Clamps induced surges to ≤56 V within 1 ns, preventing false torque reporting or steering assist interruption during EMC immunity testing (ISO 11452-4). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher capacitance (12 pF typical), lower clamping voltage (≤40 V @ 1 A), not AEC-Q101 qualified | Targeted at industrial/commercial CAN nodes; lacks automotive temperature and reliability validation | Prefer when cost sensitivity outweighs AEC-Q101 requirement and board layout allows higher capacitance |
| Infineon ESD204-B1-02EL | Lower stand-off (24 V), smaller SOT-23-3L package, same ±30 kV ESD rating, AEC-Q101 qualified | Optimized for space-constrained 24 V systems (e.g., commercial vehicles); insufficient for 33 V CAN bias margin | Select only if system operates below 24 V common-mode and PCB real estate is critical |
Compared with NUP4202MR6T1G and ESD204-B1-02EL, the VCAN33A2-03G-E3-08 uniquely balances 33 V stand-off, sub-10 pF capacitance, AEC-Q101 qualification, and SOT-323 manufacturability - making it the only option among the three validated for 12 V automotive CAN FD designs requiring full OEM compliance.

FAQ
What is the maximum operating junction temperature for VCAN33A2-03G-E3-08?
The VCAN33A2-03G-E3-08 has a maximum junction temperature (TJ) of +175 °C, verified per AEC-Q101 stress testing. This rating enables direct use in under-hood applications such as engine control units or battery disconnect units without thermal derating, provided PCB copper area and airflow meet Vishay's recommended thermal pad layout in document 86152.
Does VCAN33A2-03G-E3-08 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN33A2-03G-E3-08 supports CAN FD operation up to 5 Mbps due to its low and tightly matched capacitance (8.7–9.7 pF) and fast response time (<1 ns). Measured signal integrity tests confirm <0.5% rise-time degradation on 5 Mbps differential waveforms when placed adjacent to TI TCAN1051H or NXP TJA1043 transceivers.
Is VCAN33A2-03G-E3-08 pin-compatible with earlier VCAN33A2 variants?
Yes, VCAN33A2-03G-E3-08 uses the identical SOT-323 package and pinout as all VCAN33A2-x variants (e.g., VCAN33A2-03G-E3-18), including Pin 1 (CH1 anode), Pin 2 (CH2 anode), and Pin 3 (common cathode). The "-08" suffix denotes 3,000-unit 7" reel packaging - no electrical or mechanical changes.
What is the clamping voltage of VCAN33A2-03G-E3-08 at 1 A and 2.5 A peak pulse current?
Per Vishay datasheet 86152, the VCAN33A2-03G-E3-08 clamps to ≤46 V at 1 A (8/20 μs) and ≤56 V at 2.5 A (8/20 μs). These values are measured per IEC 61000-4-5 and ensure safe operation below the 60–70 V absolute maximum ratings of most CAN transceivers, including ST TJA1042 and Microchip MCP2561FD.
How does the BiSy architecture benefit CAN bus protection design?
The BiSy (bidirectional symmetrical) architecture of VCAN33A2-03G-E3-08 provides identical electrical characteristics in both polarities - eliminating orientation constraints during PCB layout and ensuring consistent clamping on CAN_H and CAN_L regardless of transient polarity. This simplifies routing, reduces BOM variants, and improves yield in high-volume automotive manufacturing.
