Product details
Overview
ESDCAN06-2BWY from STMicroelectronics is an AEC-Q101-qualified dual-line transient voltage suppressor (TVS) designed for bidirectional ESD and EOS protection of CAN H and CAN L signal lines in automotive networks. It features a 38 V breakdown voltage (VBR), 59 V clamping voltage (VCL) at 3 A (8/20 µs), 13–15 pF line-to-ground capacitance, and supports ISO 10605 ±30 kV (contact/air) and ISO 7637-3 Pulse 3a/3b (±150 V). It is used in high-speed CAN FD and LIN bus interfaces requiring low-capacitance, robust EMC immunity.
For engineers reviewing the ESDCAN06-2BWY datasheet, ESDCAN06-2BWY pinout, ESDCAN06-2BWY application, or ESDCAN06-2BWY equivalent, key selection criteria include its 38 V VBR, 13–15 pF capacitance, SOT323-3L package compatibility with IPC7531 footprints, and compliance with ISO 16750-2, ISO 10605 Level 4, and IEC 61000-4-4 EFT.
Technical Context
This device implements a dual-channel, bidirectional TVS diode array optimized for CAN physical layer protection. Its low clamping factor (VCL/VBR ≈ 1.55) ensures minimal bus disturbance during transients, while its 13–15 pF capacitance between IO1/IO2 and GND preserves signal integrity on CAN FD buses up to 5 Mbps.
The SOT323-3L package integrates two independent TVS junctions sharing a common cathode (Pin 3), enabling compact placement directly at CAN connector entry points. Thermal design leverages a -55 °C to +175 °C operating junction temperature range and MSL Level 1 moisture sensitivity rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 35 V - Ensures reliable standoff above CAN bus common-mode voltage (±12 V) with margin against false triggering |
| VBR (typ) | 38 V - Precise breakdown threshold aligned with ISO 7637-3 Pulse 2a/3a/3b protection levels |
| VCL @ 3 A (8/20 µs) | 59 V - Clamps transients below CAN transceiver absolute maximum ratings (typically 60–70 V) |
| C (IO1/IO2 to GND) | 13–15 pF - Enables <5 Mbps CAN FD operation without signal rise-time degradation |
| IPP (8/20 µs) | 3 A - Supports ISO 10605 30 kV discharges with C = 330 pF / R = 330 Ω |
| Leakage (IR @ VRM) | 0.1 µA max - Negligible DC loading on CAN bias network and termination resistors |
| Operating Tj | -55 °C to +175 °C - Validated for under-hood automotive environments including engine control modules |
Pinout & Package
ESDCAN06-2BWY is housed in a JEDEC-registered SOT323-3L package (3-pin, surface-mount, gull-wing leads) with ECOPACK2 RoHS compliance and IPC7531 footprint alignment. The package measures 2.00 mm × 1.25 mm × 0.95 mm (max) and supports reflow per J-STD-020 MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (IO1) | CAN H line TVS anode | Connects to CAN H signal path; clamps positive/negative transients to common cathode |
| Pin 2 (IO2) | CAN L line TVS anode | Connects to CAN L signal path; enables symmetrical dual-line protection with shared cathode |
| Pin 3 (GND) | Common cathode | Low-inductance ground return for both channels; must be routed to chassis or low-impedance system ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use across temperature, humidity, and mechanical stress cycles per JESD47 |
| Dual-line bidirectional protection | Single-device solution for simultaneous CAN H and CAN L line protection without external components |
| Low clamping factor (VCL/VBR) | ≈1.55 - Limits bus overvoltage to safe levels while minimizing data corruption risk during ESD events |
| Low line capacitance (13–15 pF) | Preserves signal edge rate on CAN FD buses; avoids timing skew and bit error increase |
| ISO 10605 Level 4 compliance | Withstands ±30 kV contact/air discharge using multiple capacitor-resistor configurations (150/330 pF, 330/2 kΩ) |
Applications
| Automotive CAN FD Node | Body Control Module (BCM) |
|---|---|
Use Scenario: High-speed communication node in ADAS domain controller requiring 2 Mbps+ CAN FD data throughput with ESD immunity. IC Role / Device Role / Timing Role: Dual-line TVS protecting CAN transceiver PHY inputs from connector-level ESD and load dump transients.

IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on LIN bus pins to prevent microcontroller reset during panel button actuation. Use Value: 0.1 µA leakage avoids loading LIN pull-up resistor; 38 V VBR provides margin above LIN's 12 V supply rail. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN bus TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDCAN05-2BWY | VBR = 39 V (vs. 38 V); VCL = 61 V @ 3 A; capacitance = 3–3.5 pF | Better suited for 5 V CAN transceivers with tighter VCC margins; lower capacitance reduces jitter but raises VCL | Select when clamping voltage margin >2 V is available and ultra-low capacitance is prioritized over lowest VCL |
| TPD2E001DRYR | Single-channel, 5.5 V VBR; 12 pF; not AEC-Q101 qualified; no ISO 7637-3 support | Only suitable for non-automotive, low-voltage (3.3 V) CAN/LIN interfaces; lacks automotive transient standards compliance | Use only in industrial or consumer-grade CAN nodes where AEC-Q101 and ISO 7637-3 are not required |
Compared with ESDCAN05-2BWY, ESDCAN06-2BWY offers lower clamping voltage (59 V vs. 61 V) at identical current, improving safety margin for 12 V CAN transceivers; compared with TPD2E001DRYR, it delivers full automotive qualification and multi-standard transient immunity essential for OEM deployment.

FAQ
What is the maximum peak pulse current ESDCAN06-2BWY can handle?
ESDCAN06-2BWY supports a peak pulse current (IPP) of 3 A under 8/20 µs waveform conditions, validated per ISO 10605 with 330 pF/330 Ω and 150 pF/330 Ω test configurations. This rating corresponds to ±30 kV contact/air discharge immunity and aligns with its 59 V clamping voltage at that current level.
Is ESDCAN06-2BWY compatible with CAN FD data rates up to 5 Mbps?
Yes-its 13–15 pF line-to-ground capacitance introduces negligible signal distortion on differential CAN FD waveforms. Measured S21 attenuation remains below -1 dB up to 1 GHz, preserving rise/fall times required for 5 Mbps operation without violating ISO 11898-2 eye diagram masks.
How does the SOT323-3L package affect PCB layout for optimal ESD performance?
Optimal layout requires short, symmetric traces from CAN H/L pins to ESDCAN06-2BWY Pins 1 and 2, with Pin 3 (GND) connected to a solid ground plane via multiple vias within 2 mm. The 0.65 mm pitch and 1.25 mm width enable dense routing near connectors while maintaining low parasitic inductance (<0.5 nH) critical for fast transient response.
Does ESDCAN06-2BWY require external biasing or supporting components?
No-ESDCAN06-2BWY operates passively as a bidirectional TVS diode array and requires no external power, bias resistors, or capacitors. It functions solely between CAN H, CAN L, and GND, making it a drop-in protection solution compatible with all standard CAN transceivers including TJA1042, SN65HVD230, and TCAN1042.
