Product details
Overview
VCAN36A2-03G-E3-18 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, rated for ±36 V working voltage, <0.05 μA reverse leakage, <10 pF load capacitance, and ±30 kV IEC 61000-4-2 ESD immunity - designed for CAN bus signal line protection in automotive and industrial networks.
For engineers reviewing the VCAN36A2-03G-E3-18 datasheet, VCAN36A2-03G-E3-18 pinout, VCAN36A2-03G-E3-18 application, or VCAN36A2-03G-E3-18 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, SOT-323 terminal mapping, low-capacitance design rationale, and direct alternatives for CAN transceiver interface protection.
Technical Context
This device implements a symmetrical dual-channel TVS architecture with matched clamping characteristics across both protected lines (pins 1–3 and 2–3), enabling balanced transient suppression on differential CAN H/L pairs without polarity sensitivity. Its BiSy topology eliminates need for orientation-aware layout and supports bidirectional data flow integrity.
Designed specifically for high-speed serial buses, it maintains signal fidelity via ultra-low 8 pF typical capacitance at 0 V bias and clamps transients to ≤63 V at 2.4 A peak pulse current (IEC 61000-4-5, 8/20 μs), while sustaining operation from −55 °C to +175 °C junction temperature per AEC-Q101 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line TVS - enables polarity-agnostic placement on CAN H/L lines without signal inversion or routing constraints |
| Working Voltage (VRWM) | ±36 V - matches nominal CAN bus common-mode range and withstands sustained transients up to system rail limits |
| Clamping Voltage (VC) | ≤63 V at 2.4 A (8/20 μs) - ensures downstream CAN transceiver ICs (e.g., ISO1050, TJA1042) remain within absolute maximum ratings during surge events |
| Capacitance (CD) | 8 pF typical at 0 V, 1 MHz - preserves signal edge integrity for >1 Mbps CAN FD data rates with minimal rise-time degradation |
| ESD Immunity | ±30 kV contact / air discharge (IEC 61000-4-2) - exceeds automotive OEM requirements for infotainment and body control module interfaces |
| AEC-Q101 Qualified | Yes (H3B HBM >8 kV) - validated for under-hood and chassis-mounted applications requiring extended temperature cycling and mechanical robustness |
| Leakage Current (IR) | <0.05 μA at 36 V - prevents measurable DC loading on bias-sensitive CAN termination networks or low-power wake-up circuits |
Pinout & Package
SOT-323 package: 3-terminal surface-mount plastic case, 2.2 mm × 1.35 mm footprint, MSL level 1, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 Anode/Cathode (BiSy) | Connects to CAN_H or CAN_L; symmetric conduction allows use on either line without polarity assignment |
| Pin 2 | Line 2 Anode/Cathode (BiSy) | Connects to complementary CAN line; independent but matched clamping path to common pin 3 |
| Pin 3 | Common Cathode/Anode Reference | Shared low-impedance return node for both protection paths; must connect to ground plane with minimal inductance |
Key Features
| Feature | Design Value |
|---|---|
| BiSy Dual-Line Architecture | Eliminates orientation dependency in PCB layout - reduces design iterations and assembly errors on differential bus traces |
| Low 8 pF Capacitance | Minimizes signal distortion on CAN FD (up to 5 Mbps) and legacy CAN (125 kbps–1 Mbps) without requiring trace length compensation |
| ±30 kV ESD Rating | Meets and exceeds ISO 10605 (330 Ω/150 pF) test requirements for vehicle-level ESD immunity validation |
| AEC-Q101 H3B Qualification | Validated for 1000-cycle temperature cycling (−55 °C to +175 °C), mechanical shock, and humidity exposure per automotive reliability standards |
| e3 Tin Plating | RoHS-compliant matte tin terminations ensure solderability stability and eliminate lead-free reflow compatibility concerns |
Applications

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 | Lower VRWM (5 V), higher CD (15 pF), same SOT-323 package and ±30 kV ESD rating | Targeted at 3.3 V/5 V logic-level buses (USB, I²C), not suitable for 12 V/24 V CAN common-mode ranges | Select only for low-voltage digital interfaces; incompatible with CAN due to insufficient standoff voltage |
| LITTELFUSE SP1003-04UTG | Higher VRWM (36 V), identical BiSy dual-line structure, but SOD-323 package (slightly larger footprint, 2.7 mm × 1.7 mm) | Same CAN/FlexRay use case; requires PCB land pattern revision due to 0.5 mm longer body and different pad spacing | Drop-in replacement electrically; mechanical redesign needed for pad layout and stencil aperture |
Compared with RCLAMP0524P.TCT and SP1003-04UTG, VCAN36A2-03G-E3-18 uniquely combines CAN-optimized ±36 V standoff, sub-10 pF capacitance, and AEC-Q101 qualification in the compact SOT-323 outline - making it the only option qualified for automotive under-hood deployment without footprint change or voltage derating.

FAQ
What is the maximum peak pulse current rating for VCAN36A2-03G-E3-18?
The VCAN36A2-03G-E3-18 is rated for 2.4 A peak pulse current per line (IEC 61000-4-5, 8/20 μs waveform). This value is measured pin-to-pin (e.g., pin 1 to pin 3) under single-shot conditions at 25 °C ambient, and defines the maximum transient energy the device can safely shunt without parametric shift or failure.
Is VCAN36A2-03G-E3-18 qualified to AEC-Q101, and what stress tests does that include?
Yes, VCAN36A2-03G-E3-18 is AEC-Q101 qualified (H3B class, >8 kV HBM). The qualification includes temperature cycling (−55 °C to +175 °C, 1000 cycles), high-temperature operating life (1000 h at TJ = 175 °C), mechanical shock, and humidity exposure - all performed per JEDEC JESD22 standards to validate suitability for automotive under-hood applications.
How does the BiSy architecture of VCAN36A2-03G-E3-18 simplify PCB layout versus asymmetric dual-diode arrays?
The BiSy architecture of VCAN36A2-03G-E3-18 provides identical forward and reverse conduction characteristics on both protected lines, eliminating polarity marking and orientation constraints. Unlike asymmetric arrays, it allows direct placement on CAN_H or CAN_L without regard to anode/cathode direction - reducing layout errors and enabling single-footprint reuse across multiple CAN nodes in VCAN36A2-03G-E3-18-based designs.
What is the typical capacitance of VCAN36A2-03G-E3-18, and why is it critical for CAN FD applications?
VCAN36A2-03G-E3-18 has a typical capacitance of 8 pF at 0 V and 1 MHz. This low value is critical for CAN FD (up to 5 Mbps) because excessive capacitance distorts signal edges, increases bit error rate, and degrades common-mode rejection - especially on long stubs or multi-node buses where cumulative loading exceeds 30 pF. At 8 pF, VCAN36A2-03G-E3-18 adds negligible loading to standard 120 Ω termination networks.
Can VCAN36A2-03G-E3-18 be used to protect non-CAN interfaces like LIN or FlexRay?
VCAN36A2-03G-E3-18 is optimized for CAN (ISO 11898-2) with ±36 V standoff and BiSy symmetry, but its electrical specs also support FlexRay (±30 V nominal) when used with appropriate external filtering. It is not recommended for LIN (12 V max) due to excessive standoff voltage causing higher clamping thresholds than necessary - use dedicated LIN-rated protectors (e.g., VCAN24A2) instead. VCAN36A2-03G-E3-18 remains valid only where ±36 V working range aligns with bus architecture.
