Product details
Overview
VCAN36A2-03SHE3A08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-23 package, designed for CAN and FlexRay bus interfaces. It provides ±36 V working voltage range, <0.05 μA reverse leakage, <10 pF load capacitance, and ±30 kV IEC 61000-4-2 ESD immunity - enabling robust signal integrity in automotive controller area networks.
For engineers reviewing the VCAN36A2-03SHE3A08 datasheet, VCAN36A2-03SHE3A08 pinout, VCAN36A2-03SHE3A08 application, or VCAN36A2-03SHE3A08 equivalent, key selection criteria include its AEC-Q101 qualification, low clamping voltage (55–63 V at 2.4 A), dual-channel symmetry, and SOT-23 footprint compatibility with space-constrained automotive PCB layouts.
Technical Context
The VCAN36A2-03SHE3A08 implements a dual-channel, bidirectional TVS structure with symmetrical breakdown behavior across both lines (pins 1–3 and 2–3), supporting differential bus protocols without polarity constraints. Its silicon avalanche junction design delivers precise clamping response to transient surges per IEC 61000-4-5 (8/20 μs waveform) and meets AEC-Q101 H3B human body model (>8 kV) requirements.
It operates over –55 °C to +150 °C junction temperature, uses tin-plated e3 terminations, and is qualified to MSL level 1 with peak reflow tolerance up to 260 °C - confirming suitability for automotive under-hood and infotainment module assembly processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line TVS for differential bus protection |
| Working Voltage (VRWM) | ±36 V - matches nominal CAN transceiver supply rails and withstands common-mode transients |
| Clamping Voltage (VC) | 55–63 V at 2.4 A peak pulse - limits voltage seen by downstream CAN PHY during surge events |
| Capacitance (CD) | 8–10 pF at 0 V - preserves signal edge rate and minimizes bit error in high-speed CAN FD (up to 5 Mbps) |
| ESD Immunity | ±30 kV contact/air discharge (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements |
| AEC-Q101 Qualification | H3B-class (>8 kV HBM) - validated for automotive powertrain and body electronics applications |
| Leakage Current (IR) | <0.05 μA at 36 V - avoids loading on high-impedance CAN bus termination networks |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to CAN_H or first protected line; forms symmetrical clamp path with Pin 3 |
| Pin 2 | Anode of Channel 2 | Connects to CAN_L or second protected line; identical electrical behavior to Pin 1 |
| Pin 3 | Cathode (common) | Shared cathode node tied to ground or low-impedance reference; enables dual-channel integration in single footprint |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional symmetry | Identical clamping performance for positive/negative transients on both lines - eliminates polarity-sensitive layout constraints |
| Low capacitance | 8–10 pF ensures minimal signal distortion on CAN FD buses operating up to 5 Mbps |
| AEC-Q101 H3B rating | Validated >8 kV HBM ESD robustness - required for automotive ECUs in engine control and ADAS domains |
| e3 tin plating | RoHS-compliant, lead-free terminations with proven solderability and intermetallic reliability in thermal cycling |
| MSL level 1 handling | No dry-pack or baking required before SMT assembly - reduces manufacturing overhead in high-volume automotive production |
Applications
| Automotive CAN Bus Nodes | FlexRay Communication Modules |
|---|---|
Use Scenario: Protection of CAN_H/CAN_L lines in engine control units exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between connector and CAN transceiver IC. Use Value: Clamps 2.4 A surges to ≤63 V while adding only 9 pF capacitance - maintains CAN signal integrity and prevents PHY latch-up. | Use Scenario: ESD hardening of FlexRay physical layer in chassis domain controllers requiring deterministic timing. IC Role / Device Role / Timing Role: Dual-line bidirectional protector on differential FlexRay A/B channels. Use Value: Symmetrical ±30 kV ESD immunity and sub-10 pF loading preserve 10 Mbps FlexRay signal rise/fall times and jitter margin. |

IC Role / Device Role / Timing Role: Front-end transient suppressor for high-speed CAN FD links carrying sensor data. Use Value: 55–63 V clamping at 2.4 A ensures downstream CAN FD transceivers remain within safe SOA during coupled surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NUP4202MR6T1G | Higher VRWM (±24 V), higher CD (15 pF), lower IPPM (1.5 A), not AEC-Q101 qualified | Targeted at industrial CAN, not automotive-grade; unsuitable for under-hood environments | Select when cost sensitivity outweighs AEC-Q101 compliance and higher capacitance is acceptable |
| TPD2E001DRYR | Lower VRWM (±5.5 V), ultra-low CD (1.5 pF), no AEC-Q101 qualification, 2-line but unidirectional | Designed for USB/low-voltage data lines - incompatible with 36 V CAN bus operating range | Use only for non-automotive, low-voltage serial interfaces where clamping voltage must be <12 V |
Compared with NUP4202MR6T1G and TPD2E001DRYR, the VCAN36A2-03SHE3A08 uniquely combines AEC-Q101 qualification, ±36 V standoff, and sub-10 pF capacitance - making it the only option among the three validated for automotive CAN FD nodes requiring both high-voltage resilience and signal fidelity.

FAQ
What is the maximum peak pulse current rating for VCAN36A2-03SHE3A08?
The VCAN36A2-03SHE3A08 is rated for 2.4 A peak pulse current (IPPM) per channel under IEC 61000-4-5 8/20 μs waveform conditions at 25 °C. This value reflects single-shot capability and is validated across both protected lines (Pin 1–3 and Pin 2–3). The device maintains clamping voltage below 63 V at this current, ensuring downstream CAN transceivers remain within safe operating area.
Is VCAN36A2-03SHE3A08 qualified for automotive under-hood applications?
Yes, VCAN36A2-03SHE3A08 is AEC-Q101 qualified (H3B class) and rated for junction temperatures from –55 °C to +150 °C. Its MSL level 1 moisture sensitivity and 260 °C peak reflow tolerance confirm suitability for under-hood environments where thermal cycling and humidity exposure are critical. The device is widely deployed in engine control units and transmission control modules.
Does VCAN36A2-03SHE3A08 support CAN FD data rates up to 5 Mbps?
Yes, VCAN36A2-03SHE3A08 supports CAN FD operation up to 5 Mbps due to its typical 9 pF capacitance at 0 V and symmetrical clamping behavior. Measured capacitance remains below 10 pF across the full 0–36 V reverse bias range, minimizing signal rise-time degradation and maintaining eye diagram integrity required for reliable high-speed CAN FD communication.
What is the pin configuration and recommended PCB footprint for VCAN36A2-03SHE3A08?
VCAN36A2-03SHE3A08 uses a standard SOT-23 package with Pin 1 (anode, CAN_H), Pin 2 (anode, CAN_L), and Pin 3 (common cathode, ground). Vishay recommends the SOT-23 footprint per document S8-V-3929.01-009, including 0.95 mm pad width, 1.3 mm pad length, and 2.425 mm center-to-center spacing - matching industry-standard SMT placement equipment.
How does the bidirectional symmetry of VCAN36A2-03SHE3A08 benefit CAN bus layout?
The bidirectional symmetry of VCAN36A2-03SHE3A08 eliminates polarity dependency on CAN_H and CAN_L lines, allowing either pin to connect to either bus line without performance penalty. This simplifies PCB routing, reduces risk of assembly errors, and enables single BOM item usage across multiple CAN node designs - directly improving manufacturing yield and reducing validation effort for VCAN36A2-03SHE3A08-based systems.
