ESDL031-1BF4 Description

Short technical summary and product information.

The STMicroelectronics ESDL031-1BF4 is a bidirectional Zener TVS diode designed to protect sensitive electronics from voltage transients. It features a reverse standoff voltage of 3.3V and a clamping voltage of 7V, providing effective overvoltage protection for low-voltage circuits.

 

With a peak pulse power rating of 45W and a peak pulse current of 7A (8/20µs), this device can handle moderate transient events. Its low capacitance of 10pF at 1MHz makes it suitable for high-speed signal lines where signal integrity is critical.

 

This TVS diode is housed in a compact 0201 (0603 Metric) surface mount package with the supplier device package designation ST0201. It is rated for operation over a junction temperature range of -55°C to 150°C, making it suitable for demanding environments including automotive applications.
