Product details
Overview
VCAN36A2-03S-E3-18 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-23 package, rated for ±36 V working voltage, <10 pF capacitance, and ±30 kV IEC 61000-4-2 ESD immunity-designed specifically for CAN bus signal line protection in automotive and industrial networks.
For engineers reviewing the VCAN36A2-03S-E3-18 datasheet, VCAN36A2-03S-E3-18 pinout, VCAN36A2-03S-E3-18 application, or VCAN36A2-03S-E3-18 equivalent, key selection criteria include low clamping voltage (55–63 V at 2.4 A), AEC-Q101 qualification, tin-plated e3 terminations, and dual-channel layout compatibility with standard CAN transceiver interfaces.
Technical Context
This device implements a symmetrical dual-diode architecture with common cathode configuration (Pin 3 = GND), enabling simultaneous bidirectional transient suppression on two independent signal lines (Pin 1 and Pin 2). Each channel supports ±36 V DC operating range and clamps transients to ≤63 V at 2.4 A peak pulse current per IEC 61000-4-5.
It meets AEC-Q101 stress requirements including HBM >8 kV and delivers <0.05 μA reverse leakage at 36 V, making it suitable for low-power, high-reliability CAN FD and legacy CAN systems where signal integrity and ESD robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line ESD clamp for CAN bus signals |
| Working Voltage (VRWM) | ±36 V - matches nominal CAN bus common-mode range and withstands supply rail variations |
| Clamping Voltage (VC) | 55–63 V at 2.4 A (8/20 µs) - ensures downstream CAN transceiver remains within safe SOA during surge events |
| Capacitance (CD) | 8–10 pF at 0 V - preserves signal edge rate and minimizes bit error risk in 1 Mbps+ CAN FD applications |
| ESD Rating | ±30 kV contact/air (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements |
| AEC-Q101 Qualified | Yes, H3B class (>8 kV HBM) - validated for under-hood and chassis-mounted automotive electronics |
| Leakage Current (IR) | <0.05 μA at 36 V - avoids loading of high-impedance CAN bias networks |
Pinout & Package
SOT-23 package (3-pin, 2.9 mm × 1.3 mm × 1.01 mm), MSL level 1, lead (Pb)-free with e3 tin plating, compatible with standard reflow profiles (peak 260 °C).

| Pin 1 | Anode of Channel 1 | Connects to first protected CAN signal line (e.g., CAN_H) |
| Pin 2 | Anode of Channel 2 | Connects to second protected CAN signal line (e.g., CAN_L) |
| Pin 3 | Common Cathode / GND | Reference node for both clamping paths; must connect to clean system ground |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line BiSy architecture | Enables matched clamping on both CAN_H and CAN_L without polarity sensitivity or external biasing |
| Low 8–10 pF capacitance | Maintains signal integrity up to 5 Mbps CAN FD data rates with minimal rise-time degradation |
| ±30 kV IEC 61000-4-2 rating | Eliminates need for secondary board-level ESD mitigation in cost-sensitive automotive modules |
| AEC-Q101 H3B qualification | Validates reliability for 15-year automotive service life under thermal cycling and humidity exposure |
| e3 tin-plated terminations | Ensures solderability and intermetallic formation control in lead-free assembly processes |

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 |
|---|---|---|---|
| STUSB4710QTR | Integrated USB-C PD controller with built-in ESD protection; not a discrete diode; higher system integration but no CAN-specific optimization | Designed for USB power delivery, not CAN bus; lacks ±36 V VRWM and BiSy symmetry | Select only when combining USB-C port control and basic ESD-not for dedicated CAN protection |
| ON Semiconductor NUP4202MR6T1G | Quad-channel ESD array; 15 pF typical capacitance; ±24 V VRWM; lower voltage rating and higher capacitance than VCAN36A2-03S-E3-18 | Used in general-purpose I/O protection; insufficient for 36 V CAN common-mode tolerance and marginal for 5 Mbps CAN FD | Acceptable only for 12 V CAN systems with relaxed speed or non-AEC-Q101 requirements |
Compared with STUSB4710QTR and NUP4202MR6T1G, the VCAN36A2-03S-E3-18 delivers superior CAN-specific performance: tighter ±36 V standoff, lower 8–10 pF capacitance, and AEC-Q101 H3B validation-making it the only option qualified for automotive-grade dual-line CAN FD protection without design compromise.

FAQ
What is the maximum peak pulse current rating for VCAN36A2-03S-E3-18?
The VCAN36A2-03S-E3-18 is rated for 2.4 A peak pulse current per channel under IEC 61000-4-5 (8/20 µs waveform) at 25 °C. This value is specified for single-shot conditions and reflects the device's ability to safely divert transient energy without parametric shift or failure. Derating applies above 25 °C ambient per the junction temperature limit of -55 °C to +150 °C.
Is VCAN36A2-03S-E3-18 pin-compatible with other Vishay CAN protection diodes like VCAN36A2-03J?
No-VCAN36A2-03S-E3-18 uses SOT-23 packaging with three terminals (dual-anode/common-cathode), while VCAN36A2-03J is in SOD-323 and has different footprint and thermal characteristics. The pinout and land pattern are not interchangeable; PCB layout must match the SOT-23 mechanical dimensions and orientation shown in Vishay document 86207.
Does VCAN36A2-03S-E3-18 support CAN FD data rates up to 5 Mbps?
Yes-VCAN36A2-03S-E3-18 supports CAN FD operation up to 5 Mbps due to its low 8–10 pF capacitance and symmetrical clamping behavior, which preserves signal edge fidelity and differential timing. Measured TLP data confirms sub-63 V clamping at 2.4 A, ensuring receiver input thresholds remain unviolated even during fast transients.
What does the "E3" suffix indicate in VCAN36A2-03S-E3-18?
The "E3" suffix in VCAN36A2-03S-E3-18 denotes Vishay's e3 termination standard: lead (Pb)-free terminations with 100 % matte tin plating, compliant with JEDEC JS-001 and RoHS Directive 2011/65/EU. It ensures reliable solder joint formation and intermetallic growth control in lead-free reflow processes.
Can VCAN36A2-03S-E3-18 be used in 24 V industrial CAN systems?
Yes-VCAN36A2-03S-E3-18 is rated for ±36 V reverse stand-off voltage, making it fully compatible with 24 V industrial CAN systems that may experience load dump or battery reversal transients. Its clamping voltage remains below 63 V at full rated current, protecting downstream transceivers rated for 36 V absolute maximum ratings.
