STMicroelectronics ESDCAN04-2BLY is a 1-element bi-directional TVS diode designed for protection against electrostatic discharge (ESD) and electrical overstress in automotive and other industrial electronics systems. It offers a peak pulse power dissipation of 230 W (with an 8/20 µs waveform) ensuring effective transient voltage suppression on sensitive CAN bus and communication lines.
The diode is packaged in a compact 3-pin SOT-23 surface mount package that facilitates easy PCB mounting in space-constrained designs. Operating reliably in temperatures ranging from -55°C up to 150°C, it suits harsh automotive environments and industrial applications. The device exhibits a minimum breakdown voltage of 27.5 V and a clamping voltage of 43 V to protect circuitry from voltage spikes.
Designed to comply with automotive standard AEC-Q101, this TVS diode supports key automotive communication protocols such as CAN-FD, LIN, FlexRay, MOST, SENT, and USB interfaces. Its low maximum reverse leakage current of 50 nA ensures minimal quiescent power consumption.
The physical dimensions of the device are 3.04 mm in length, 1.75 mm in width, and 1.1 mm in height, making it suitable for modern compact electronic assemblies. Applications include automotive CAN bus protection, industrial control systems, and general purpose line protection where robust ESD safeguarding is required.
Single diode, bi-directional configuration for dual-line protection. High pulse power rating of 230 W to absorb severe transient events. Surface mount SOT-23 package supports high-density PCB layouts. Wide temperature range of -55°C to 150°C for automotive and industrial environments.
Low leakage current of 50 nA ensures energy efficiency during normal operation. Automotive compliant AEC-Q101 ensures quality and reliability in demanding systems. Explore more products in the TVS Diode category to find additional solutions for electrostatic and transient voltage protection.
