ESDALC20-1BF4 Description

Short technical summary and product information.

The ESDALC20-1BF4 from STMicroelectronics is a Zener-type TVS diode designed for general purpose ESD protection. It features a reverse standoff voltage of 20 V and a clamping voltage of 37 V, capable of handling a peak pulse current of 2.4 A (8/20 µs) with a peak pulse power rating of 90 W. The diode has a low capacitance of 10.5 pF at 1 MHz, making it suitable for high-speed signal line protection. It is a single bidirectional channel device, offering symmetrical protection without power line protection. The operating temperature range is -40°C to 150°C. Packaged in a 0201 (0603 metric) surface mount package, it is ideal for space-constrained designs. The component is RoHS3 compliant and has an MSL of 1 (unlimited).
