Product details
Overview
VCAN36A2-03S-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-23 package, designed for CAN bus and FLEX-bus interfaces. It provides ±36 V reverse stand-off voltage, <0.05 μA leakage current at 36 V, <10 pF load capacitance, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the VCAN36A2-03S-E3-08 datasheet, VCAN36A2-03S-E3-08 pinout, VCAN36A2-03S-E3-08 application, or VCAN36A2-03S-E3-08 equivalent, key selection criteria include low-capacitance dual-line protection, AEC-Q101 compliance, SOT-23 footprint compatibility, and clamping performance under 8/20 μs surge conditions.
Technical Context
The VCAN36A2-03S-E3-08 integrates two identical, symmetrical ESD protection paths between pins 1–3 and 2–3, enabling bidirectional transient suppression on two independent signal lines. Its silicon avalanche structure delivers precise clamping with typical breakdown at 42 V and clamping voltage ≤54 V at 1 A IPP.
Designed specifically for high-speed serial buses, it maintains signal integrity via ultra-low 8 pF typical capacitance at 0 V bias and supports robust system-level ESD resilience per IEC 61000-4-2 (±30 kV contact/air) and AEC-Q101 H3B human body model (>8 kV).
Key Specifications

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 |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Unidirectional configuration; 5.5 V VRWM; 0.5 pF lower capacitance (7.5 pF typ) | Requires separate ground-referenced placement per line; not suitable for BiSy differential bus topologies | Select only when protecting single-ended signals or where lower capacitance outweighs bidirectional capability |
| LITTELFUSE SP3205-01UTG | Single-channel device; 3.3 V VRWM; 0.3 pF capacitance; no AEC-Q101 qualification | Needs two devices per CAN pair; limited to low-voltage logic-level interfaces, not 12 V automotive buses | Use only in non-automotive, low-voltage embedded systems with strict capacitance budgets |

FAQ
What is the maximum clamping voltage of the VCAN36A2-03S-E3-08 under 2.4 A surge current?
The VCAN36A2-03S-E3-08 exhibits a maximum clamping voltage of 63 V at IPP = 2.4 A (8/20 μs waveform), as specified in its electrical characteristics table. This value ensures downstream CAN transceivers remain within safe operating voltage limits during severe surge events. The clamping performance is verified across temperature and process variations per AEC-Q101 stress testing protocols.
Is the VCAN36A2-03S-E3-08 compatible with lead-free reflow soldering processes?
Yes, the VCAN36A2-03S-E3-08 features e3 tin-plated terminations and is qualified for peak reflow temperatures up to 260 °C per J-STD-020, making it fully compatible with standard lead-free soldering profiles. Its MSL level 1 rating allows unlimited floor life before assembly, eliminating bake requirements for production use.
Does the VCAN36A2-03S-E3-08 support bidirectional signal transmission on CAN bus lines?
Yes, the VCAN36A2-03S-E3-08 uses a bidirectional symmetrical (BiSy) architecture that permits full-duplex CAN signal transmission without polarity sensitivity. Its matched clamping characteristics on pins 1–3 and 2–3 preserve differential signaling integrity while suppressing transients on both CAN_H and CAN_L simultaneously.
What is the leakage current specification for VCAN36A2-03S-E3-08 at its rated working voltage?
The VCAN36A2-03S-E3-08 specifies a maximum reverse leakage current of 0.05 μA at VRWM = 36 V and TA = 25 °C. This ultra-low leakage prevents unintended loading of CAN bus termination resistors or receiver input stages, maintaining bus bias stability and minimizing quiescent power in always-on automotive modules.
Can the VCAN36A2-03S-E3-08 be used in non-automotive applications such as industrial FLEX-bus networks?
Yes, the VCAN36A2-03S-E3-08 is widely deployed in industrial FLEX-bus networks due to its ±30 kV ESD immunity, 8 pF capacitance, and robust 36 V standoff. Its AEC-Q101 qualification adds margin for extended temperature operation and mechanical shock resistance, making it suitable for factory automation, robotics, and rail signaling systems beyond automotive use.
