ESDARF02-1BU2CK Description

Short technical summary and product information.

The ESDARF02-1BU2CK is a Zener-type TVS diode from STMicroelectronics designed for general purpose ESD protection. It features a reverse standoff voltage of 3.6V and a clamping voltage of 12V. The device can handle a peak pulse current of 1A under an 8/20 µs waveform and offers a peak pulse power rating of 20W. With an ultra-low typical capacitance of 0.2 pF (measured at 200 MHz to 3 GHz), this diode is suitable for high-speed signal line protection. It is housed in a compact 0201 (0603 metric) surface mount package and operates over a junction temperature range of -40°C to 150°C. The part is RoHS3 compliant and REACH unaffected, with an MSL of 1 (unlimited).
