Product details
Overview
VCAN26A2-03G-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN bus and FLEX-bus interfaces. It provides ±30 kV IEC 61000-4-2 contact/air discharge immunity, 26.5 V reverse stand-off voltage, <13 pF typical capacitance, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the VCAN26A2-03G-E3-08 datasheet, VCAN26A2-03G-E3-08 pinout, VCAN26A2-03G-E3-08 application, or VCAN26A2-03G-E3-08 equivalent, this page delivers verified electrical parameters, package geometry, real-world clamping behavior under 8/20 μs transients, and validated alternatives for CAN physical layer protection.
Technical Context
This device implements two independent, matched, bidirectional TVS diodes in a single SOT-323 package - pins 1–3 and 2–3 - enabling symmetrical transient suppression on differential CAN H/L lines without polarity sensitivity. Its low 10–13 pF capacitance minimizes signal distortion at high-speed CAN FD rates up to 5 Mbps.
The junction operates from −55 °C to +175 °C, with peak pulse power of 150 W (8/20 μs), clamping voltage ≤40 V at 1 A and ≤50 V at 3 A, and leakage current <0.05 μA at 26.5 V - meeting stringent requirements for automotive body control modules and infotainment gateways.

Applications
| CAN Bus Transceiver Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Protecting high-speed CAN FD transceivers (e.g., TCAN1042, TJA1044) against ESD and load-dump induced transients in 12 V vehicle networks. IC Role / Device Role / Timing Role: Dual-line TVS clamp placed directly at connector interface, before transceiver input pins. Use Value: Maintains signal integrity with <13 pF loading while clamping transients to ≤40 V - preventing transceiver latch-up or permanent damage. |
Use Scenario: ESD hardening of LIN/CAN gateway nodes in door modules, seat controllers, and lighting ECUs exposed to service technician handling. IC Role / Device Role / Timing Role: Front-end protection element on external harness connectors, operating continuously across −40 °C to +125 °C ambient. Use Value: AEC-Q101 qualification and ±30 kV ESD rating ensure compliance with OEM test specs (e.g., GMW3172, Ford ES-XW7T-1A278-AC). |
| FLEX-bus Interface Protection | Industrial CAN Gateway |
|
Use Scenario: Safeguarding FLEX-bus (SAE J1939 variant) nodes in heavy-duty truck telematics units subjected to harsh vibration and thermal cycling. IC Role / Device Role / Timing Role: Bidirectional transient suppressor on differential data pair, sharing common cathode to minimize PCB area. Use Value: Symmetrical clamping and matched capacitance preserve differential timing skew - critical for error-free arbitration at 250 kbps. |
Use Scenario: Protecting industrial CAN-to-Ethernet bridges in factory automation systems where ESD events occur during field cable swaps. IC Role / Device Role / Timing Role: Secondary-level protection after connector-level gas discharge tube, providing fast sub-nanosecond response. Use Value: Low 0.05 μA leakage avoids cumulative current draw across multi-node networks - extending system uptime in unattended operation. |
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 VRWM (5.5 V), higher capacitance (18 pF), unidirectional configuration requiring external bias | Targeted at 3.3 V/5 V logic-level buses, not 12 V CAN physical layer | Select only for low-voltage digital I/O; unsuitable for direct CAN_H/L placement due to voltage mismatch and asymmetry |
| LITTELFUSE SP1003-01UTG | Single-line device (1-channel), 24 V VRWM, 12 pF, AEC-Q101 qualified | Requires two devices for full CAN differential protection - increases BOM count and layout area | Use when board space allows discrete channel implementation or when channel isolation is required beyond common-cathode topology |
Compared with RCLAMP0524P.TCT and SP1003-01UTG, the VCAN26A2-03G-E3-08 uniquely delivers matched dual-line protection at CAN-compatible 26.5 V standoff in a single SOT-323, reducing component count by 50% versus discrete solutions and avoiding voltage-level incompatibility issues seen in logic-level TVS arrays.

FAQ
What is the maximum clamping voltage of the VCAN26A2-03G-E3-08 under a 3 A 8/20 μs transient?
The VCAN26A2-03G-E3-08 exhibits a maximum clamping voltage of 50 V at 3 A peak pulse current (8/20 μs waveform), as specified in the Electrical Characteristics table. This value ensures safe operation within the absolute maximum input voltage limits of standard CAN transceivers such as the NXP TJA1042 and Texas Instruments TCAN1042, preventing latch-up or permanent damage during surge events.
Is the VCAN26A2-03G-E3-08 suitable for CAN FD applications running at 5 Mbps?
Yes, the VCAN26A2-03G-E3-08 is suitable for CAN FD applications up to 5 Mbps due to its low and tightly matched capacitance (10–13 pF at 0 V, 1 MHz) and ≤1.5 pF inter-channel capacitance mismatch. These characteristics minimize signal rise-time degradation and maintain differential timing integrity essential for reliable bit sampling at high data rates.
Does the VCAN26A2-03G-E3-08 require external biasing or direction-specific placement?
No, the VCAN26A2-03G-E3-08 uses a bidirectional symmetrical (BiSy) architecture with a common cathode (Pin 3), eliminating the need for external biasing or polarity-aware orientation. Pins 1 and 2 connect directly to CAN_H and CAN_L respectively, with identical clamping behavior in both directions - simplifying layout and reducing design risk.
What is the moisture sensitivity level (MSL) and peak reflow temperature for the VCAN26A2-03G-E3-08?
The VCAN26A2-03G-E3-08 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging or baking prior to assembly. Its peak reflow temperature is rated at 260 °C, fully compatible with standard lead-free soldering profiles used in automotive electronics manufacturing.
How does the VCAN26A2-03G-E3-08 meet AEC-Q101 requirements for automotive use?
The VCAN26A2-03G-E3-08 is fully AEC-Q101 qualified, including human body model (HBM) testing to Class H3B (>8 kV). It also meets extended temperature operation (−55 °C to +175 °C junction), mechanical shock/vibration resistance, and high-temperature storage life requirements defined in the AEC-Q101 standard - making it suitable for under-hood and safety-critical vehicle networks.
