5.0SMDJ20A Description

Short technical summary and product information.

The 5.0SMDJ20A from Littelfuse Inc. is a 5000W surface mount transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It features a Zener technology with a single unidirectional channel.

 

Key electrical specifications include a reverse standoff voltage of 20V, a maximum clamping voltage of 32.4V, and a peak pulse current rating of 155A under a 10/1000μs waveform. The device offers an ultra-fast response time of less than 1.0ps and is rated for ESD protection up to 30kV (air and contact) per IEC 61000-4-2. The operating junction temperature range is -65°C to 150°C.

 

The diode is housed in a DO-214AB (SMC) surface mount package (also known as SMCJ), providing a low profile for PCB designs. It is packaged with a glass passivated chip junction for reliability and built-in strain relief. The part is compliant with RoHS3, halogen free, and has a UL 94 V-0 flammability rating.
