Product details
Overview
VCAN16A2-03GHE3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN bus interfaces. It provides ±30 kV IEC 61000-4-2 contact/air discharge immunity, 16 V reverse stand-off voltage, <18.5 pF capacitance, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the VCAN16A2-03GHE3-08 datasheet, VCAN16A2-03GHE3-08 pinout, VCAN16A2-03GHE3-08 application, or VCAN16A2-03GHE3-08 equivalent, key selection criteria include low clamping voltage (25 V at 5 A), tight capacitance matching (<1 pF between channels), ±16 V working range, and SOT-323 footprint compatibility with high-density CAN transceiver layouts.
Technical Context
This device implements a dual-channel, symmetric TVS structure optimized for differential CAN H/L signal lines. Each channel features matched breakdown voltage (17.1–20 V), identical clamping behavior (20–23 V at 1 A; 25–28 V at 5 A), and sub-18.5 pF load capacitance to preserve signal integrity up to 1 Mbps.
It operates across –55 °C to +175 °C junction temperature, supports peak pulse power of 140 W per line (IEC 61000-4-5, 8/20 μs), and meets AEC-Q101 stress requirements including HBM Class H3B (>8 kV) - confirming suitability for under-hood automotive CAN FD and legacy CAN networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line TVS for differential CAN signals |
| Reverse Stand-off Voltage | 16 V - ensures no conduction during normal CAN bus operation (dominant/recessive states) |
| Clamping Voltage | 25–28 V at 5 A (8/20 μs) - limits transient overvoltage to safe levels for CAN transceivers |
| Capacitance | 15–18.5 pF at 0 V, 1 MHz - preserves signal edge rate and minimizes bit error rate in 1 Mbps CAN |
| ESD Immunity | ±30 kV contact & air discharge (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements |
| AEC-Q101 Qualified | Yes (H-grade option available) - validated for automotive under-hood temperature and reliability stress |
| Leakage Current | <0.05 μA at 16 V - prevents bus loading and false dominant state assertion |
Pinout & Package
SOT-323 package (3-pin, 2.2 mm × 1.35 mm × 0.95 mm), lead-free e3 tin plating, MSL Level 1, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | CAN_H protection anode/cathode | Connected to CAN_H line; bidirectional clamping path to common cathode (Pin 3) |
| Pin 2 | CAN_L protection anode/cathode | Connected to CAN_L line; bidirectional clamping path to common cathode (Pin 3) |
| Pin 3 | Common cathode reference | Shared low-impedance return node for both protection paths; must be connected to ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line matched capacitance | Capacitance mismatch ≤1 pF (CD13 vs CD23) - maintains CAN differential signal symmetry and common-mode rejection |
| High-temperature operation | Junction temperature rating up to +175 °C - enables placement near engine control units and powertrain modules |
| Low leakage current | IR ≤ 0.05 μA at VRWM = 16 V - avoids bus contention and ensures reliable recessive state detection |
| AEC-Q101 qualification | H-grade option available - fulfills automotive reliability requirements for mission-critical CAN networks |
| Small-footprint packaging | SOT-323 (2.2 × 1.35 mm) - saves PCB area in space-constrained ECUs and gateway modules |
Applications
| Automotive CAN Bus Protection | Industrial CANopen Networks |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines in engine control units exposed to ISO 7637-2 load dump and ESD events during service. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point before CAN transceiver. Use Value: Prevents latch-up or damage to CAN transceivers (e.g., TJA1042, SN65HVD230) during ±30 kV ESD strikes while maintaining <18.5 pF loading for 1 Mbps compliance. | Use Scenario: Shielding CANopen nodes in factory automation PLCs and motor drives from ESD and fast transients on long cable runs. IC Role / Device Role / Timing Role: Dual-line ESD clamp integrated into PCB-level interface protection circuitry adjacent to DB9 or M12 connectors. Use Value: Enables robust communication in noisy industrial environments without degrading signal rise/fall times due to low 16.7 pF typical capacitance. |
| Commercial Vehicle J1939 Networks | Off-Highway Equipment CAN Systems |
Use Scenario: Securing J1939 data links in heavy-duty truck ECUs where vibration, thermal cycling, and ESD are persistent failure modes. IC Role / Device Role / Timing Role: AEC-Q101-qualified ESD protector mounted on main board near CAN controller IC (e.g., NXP S32K144). Use Value: Supports extended temperature operation (–55 °C to +175 °C) and passes HBM >8 kV testing required for commercial vehicle Tier-1 suppliers. | Use Scenario: Hardening CAN interfaces in off-highway machinery (e.g., excavators, harvesters) subject to severe EMC stress and wide ambient temperature swings. IC Role / Device Role / Timing Role: Primary ESD suppression element placed between ruggedized CAN connector and isolated CAN transceiver (e.g., ADM3053). Use Value: Delivers 140 W peak pulse power handling (8/20 μs) to survive induced surges from nearby solenoid switching without degradation. |
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 |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Lower capacitance (12 pF typ), but only rated to ±20 kV ESD; not AEC-Q101 qualified | Preferred for cost-sensitive consumer CAN gateways where automotive qualification is unnecessary | Select when lower capacitance is prioritized over automotive reliability validation |
| ON Semiconductor NUP4202MR6T1G | Higher clamping voltage (33 V at 5 A); 20 pF capacitance; AEC-Q101 qualified but wider tolerance on VBR (19–23 V) | Suitable for legacy CAN systems with marginally higher voltage tolerance, less critical for high-speed timing | Choose if board layout allows slightly higher clamping and relaxed capacitance matching is acceptable |
Compared with RCLAMP0524P.TCT and NUP4202MR6T1G, VCAN16A2-03GHE3-08 uniquely balances ±30 kV ESD robustness, AEC-Q101 qualification, sub-18.5 pF capacitance, and <1 pF inter-channel matching - making it optimal for next-generation automotive CAN FD and safety-critical industrial CAN nodes requiring precise signal fidelity and proven reliability.

FAQ
What is the maximum operating temperature for VCAN16A2-03GHE3-08?
The VCAN16A2-03GHE3-08 has a maximum junction temperature of +175 °C and operates across –55 °C to +175 °C. This wide range supports placement in high-temperature zones such as near engine control modules or power inverters, and is verified per AEC-Q101 thermal cycling and high-temperature operating life tests.
Is VCAN16A2-03GHE3-08 pin-compatible with other dual-line CAN protectors like NUP4202MR6T1G?
No, VCAN16A2-03GHE3-08 is not pin-compatible with NUP4202MR6T1G. While both use SOT-323 packages, VCAN16A2-03GHE3-08 uses Pin 1 = CAN_H, Pin 2 = CAN_L, Pin 3 = common cathode; NUP4202MR6T1G uses Pin 1 = common anode, Pin 2 = CAN_H, Pin 3 = CAN_L - requiring PCB layout revision for substitution.
Does VCAN16A2-03GHE3-08 meet IEC 61000-4-5 surge immunity requirements?
Yes, VCAN16A2-03GHE3-08 is rated for 140 W peak pulse power (8/20 μs waveform, per IEC 61000-4-5) and 5 A peak pulse current per line. These values are measured with pin-to-pin configuration (e.g., Pin 1 to Pin 3), validating its capability to suppress indirect lightning-induced surges in automotive and industrial CAN installations.
What is the clamping voltage of VCAN16A2-03GHE3-08 at 1 A and 5 A transient current?
The VCAN16A2-03GHE3-08 clamps to 20–23 V at 1 A (8/20 μs) and 25–28 V at 5 A (8/20 μs). These values are specified in the Electrical Characteristics table and ensure safe voltage limiting for standard CAN transceivers rated to withstand up to 36 V absolute maximum, preserving functional integrity during ESD and surge events.
Can VCAN16A2-03GHE3-08 be used for CAN FD applications?
Yes, VCAN16A2-03GHE3-08 supports CAN FD up to 5 Mbps due to its low 15–18.5 pF capacitance and matched channel characteristics. Its <1 pF capacitance mismatch between CAN_H and CAN_L paths minimizes skew and preserves differential signal integrity essential for high-speed CAN FD timing margins.
