The SMDJ20A is a unidirectional TVS diode from Littelfuse, part of the SMDJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Key electrical specifications include a 20V reverse standoff voltage, 32.4V maximum clamping voltage, 92.6A peak pulse current (10/1000μs waveform), and 3000W peak pulse power dissipation. The device offers a response time of less than 1ps and an ESD rating of 30kV air and contact discharge per IEC 61000-4-2. It also provides EFT protection per IEC 61000-4-4 and has a forward surge current rating of 300A.
The SMDJ20A is housed in a DO-214AB (SMC) surface mount package with gull wing terminals. It operates over a temperature range of -65°C to 150°C and is RoHS3 compliant, halogen free, and MSL level 1. The package is rated UL 94 V-0 for flammability.
Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic equipment.
