20KPA104A Description

Short technical summary and product information.

The Littelfuse 20KPA104A is a unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic circuits from voltage transients. It offers a reverse standoff voltage of 104V and a breakdown voltage of 168V.

 

With a peak pulse power dissipation of 20kW (10/1000μs waveform) and a peak pulse current of 120.2A, this diode provides robust surge protection. The device features a fast response time of less than 1.0ps from 0V to breakdown voltage, ensuring rapid clamping of transient events.

 

Housed in a P600 axial leaded through-hole package, the 20KPA104A operates over a junction temperature range of -55°C to 175°C. It is RoHS compliant, halogen-free, and lead-free (Pb-free E3). The diode also meets IEC 61000-4-2 ESD protection standards for 30kV air and contact discharge.

 

Typical applications include general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
