Product details
Overview
ESDCAN06-2BLY from STMicroelectronics is an AEC-Q101-qualified dual-line bidirectional TVS diode designed for ESD and EOS protection of CAN H and CAN L signal lines in automotive networks. It features a 38 V breakdown voltage (VBR), 230 W peak pulse power (8/20 µs), 15 pF typical junction capacitance, and clamps to 59 V at 3 A IPP - enabling robust ISO 10605 ±30 kV and ISO 7637-3 Pulse 3a/3b protection in high-speed CAN-FD and LIN bus systems.
For engineers reviewing the ESDCAN06-2BLY datasheet, ESDCAN06-2BLY pinout, ESDCAN06-2BLY application, or ESDCAN06-2BLY equivalent, key selection criteria include its 38 V VBR, low 15 pF line-to-ground capacitance, SOT23-3L footprint compatibility with IPC7531, and verified compliance with ISO 16750-2 jump-start/reverse-battery tests for 12 V automotive systems.
Technical Context
This device operates as a symmetric, bidirectional transient voltage suppressor placed across CAN H and CAN L lines, with no polarity dependency. Its low clamping factor (VCL/VBR ≈ 1.55) and sub-15 pF capacitance preserve signal integrity on buses up to CAN-FD 5 Mbit/s and beyond.
The SOT23-3L package integrates two back-to-back avalanche diodes sharing a common cathode (Pin 3), delivering matched protection on both differential lines while maintaining thermal stability over –40 °C to +150 °C junction temperature range per AEC-Q101 requirements.

Pinout & Package
ESDCAN06-2BLY uses the JEDEC-registered SOT23-3L package (ECOPACK2, RoHS compliant), with 3 terminals in a compact 2.75 mm × 1.75 mm outline and 0.95 mm pitch. Pin 1 connects to CAN H, Pin 2 to CAN L, and Pin 3 serves as the common cathode/anode reference node for bidirectional clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive CAN bus protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDCAN04-2BLY | VBR = 27.5 V, CJ = 19 pF, VCL = 43 V @ 3.7 A | Better suited for 5 V logic-level CAN interfaces; higher capacitance limits CAN-FD speed to ≤2 Mbit/s | Select when lower clamping voltage is prioritized over high-speed bus support |
| ESDCAN24-2BLY | VBR = 27 V, CJ = 30 pF, VCL = 40 V @ 5.5 A | Higher capacitance degrades signal integrity above 1 Mbit/s; optimized for legacy CAN 125 kbit/s systems | Choose for cost-sensitive 12 V body electronics where bandwidth is not critical |
Compared with ESDCAN04-2BLY and ESDCAN24-2BLY, ESDCAN06-2BLY delivers superior high-speed performance via its 38 V VBR and 15 pF capacitance - enabling CAN-FD 5 Mbit/s operation while maintaining tighter clamping margin than lower-VBR variants under 12 V system overvoltage conditions.

FAQ
What is the maximum operating temperature for ESDCAN06-2BLY?
The ESDCAN06-2BLY has a specified junction temperature range of –40 °C to +150 °C, validated per AEC-Q101 stress test conditions including 1000-hour high-temperature operating life (HTOL) at 150 °C. This enables direct PCB mounting in under-hood ECUs without derating.
Does ESDCAN06-2BLY require external biasing or direction selection?
No. ESDCAN06-2BLY is inherently bidirectional due to its internal back-to-back diode configuration with a shared cathode (Pin 3). It protects both CAN H and CAN L simultaneously without polarity constraints or external components - simplifying layout and eliminating orientation errors during assembly.
How does ESDCAN06-2BLY compare to standard single-line TVS diodes in CAN protection?
Unlike single-line TVS devices requiring separate parts for CAN H and CAN L, ESDCAN06-2BLY integrates matched dual-channel protection in one SOT23-3L package. This ensures identical clamping characteristics, eliminates inter-channel timing skew, and reduces PCB area by 40% versus discrete dual-diode solutions.
Is ESDCAN06-2BLY compatible with CAN XL physical layer requirements?
Yes. With 15 pF typical junction capacitance and <1.5 ns response time, ESDCAN06-2BLY meets the low-capacitance and fast-clamping demands of CAN XL (up to 20 Mbit/s). Its 38 V VBR also aligns with CAN XL's extended common-mode voltage tolerance, supporting future-proof designs.
