Product details
Overview
VCAN26A2-03S-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-23 package, designed for CAN 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 capacitance, and <0.05 μA leakage current - enabling robust signal integrity in automotive and industrial serial bus systems.
For engineers reviewing the VCAN26A2-03S-E3-08 datasheet, VCAN26A2-03S-E3-08 pinout, VCAN26A2-03S-E3-08 application, or VCAN26A2-03S-E3-08 equivalent, this device delivers low-capacitance, AEC-Q101-qualified transient suppression for high-speed differential buses where clamping voltage stability, channel matching, and minimal signal distortion are critical selection criteria.
Technical Context
The VCAN26A2-03S-E3-08 integrates two identical, matched ESD protection paths (Pin 1–3 and Pin 2–3) in a single SOT-23-3 package, supporting bidirectional symmetrical clamping with ≤1.5 pF inter-channel capacitance mismatch across –40 °C to +125 °C. Its silicon avalanche structure ensures precise breakdown at 28–32 V (VBR, IR = 1 mA) and stable clamping of ≤50 V at 3 A (8/20 μs).
It operates within –55 °C to +150 °C junction temperature range and meets IEC 61000-4-5 surge immunity up to 150 W peak pulse power (8/20 μs), making it suitable for harsh-environment CAN transceiver I/O protection without degrading bus timing or signal rise/fall characteristics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - maximum continuous working voltage before conduction begins; preserves signal integrity during normal CAN bus operation (±12 V nominal). |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds automotive ESD requirements for controller area network nodes. |
| Capacitance | 10–13 pF at 0 V, 1 MHz - low enough to avoid signal degradation on 1 Mbps CAN FD or 5 Mbps FLEX-Bus links. |
| Clamping Voltage | ≤50 V at 3 A (8/20 μs) - limits transients to safe levels for downstream CAN transceivers (e.g., TJA1042, SN65HVD230). |
| Leakage Current | <0.05 μA at 26.5 V - negligible DC loading on bus lines, ensuring compatibility with low-power wake-up and sleep modes. |
| Package | SOT-23-3 - industry-standard footprint compatible with automated assembly and space-constrained ECUs. |

FAQ
What is the primary function of the VCAN26A2-03S-E3-08 in a CAN bus system?
The VCAN26A2-03S-E3-08 serves as a dual-line, bidirectional ESD protection diode placed at the physical interface of CAN_H and CAN_L lines. It clamps transient voltages to ≤50 V during ±30 kV ESD events while adding less than 13 pF capacitance per line - preserving signal edge rates and bus timing compliance for 1 Mbps CAN and 5 Mbps CAN FD implementations. Its matched channels ensure balanced protection without skew.
Is the VCAN26A2-03S-E3-08 qualified for automotive applications?
Yes, the VCAN26A2-03S-E3-08 is AEC-Q101 qualified, confirming its reliability under automotive temperature, humidity, and mechanical stress conditions. This qualification covers the full device family including the VCAN26A2-03S-E3-08 variant, and supports deployment in engine control units, body control modules, and ADAS subsystems where ESD robustness and long-term stability are mandatory.
Does the VCAN26A2-03S-E3-08 support bidirectional signal lines like CAN differential pairs?
Yes, the VCAN26A2-03S-E3-08 implements Bidirectional Symmetrical (BiSy) clamping architecture across both protected lines (Pin 1–3 and Pin 2–3). Each path exhibits identical forward/reverse breakdown (28–32 V) and clamping behavior, enabling seamless integration on differential buses such as CAN, FLEX-Bus, or other bidirectional serial interfaces without polarity constraints or external biasing.
What is the maximum clamping voltage of the VCAN26A2-03S-E3-08 under surge conditions?
The VCAN26A2-03S-E3-08 clamps to ≤50 V at 3 A peak pulse current (8/20 μs waveform per IEC 61000-4-5). At lower currents (e.g., 1 A), clamping is ≤40 V. This value is measured pin-to-pin (e.g., Pin 1 to Pin 3) and guarantees that downstream CAN transceivers receive transient energy within their absolute maximum ratings - a key requirement for ISO 11898-2 compliant designs.
Can the VCAN26A2-03S-E3-08 replace discrete ESD diodes in existing SOT-23 layouts?
Yes, the VCAN26A2-03S-E3-08 uses the standard SOT-23-3 footprint with 0.95 mm lead pitch and matches common land patterns (e.g., Vishay S8-V-3929.01-009). Its Pin 1/Pin 2/Pin 3 assignment aligns with conventional SOT-23 orientation, allowing drop-in replacement of single-line SOT-23 ESD diodes - though dual-line protection requires verifying shared cathode routing and ground path integrity in the layout.
