The SMAJ120A is a unidirectional TVS diode from Littelfuse, part of the SMAJ series designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 120V and a clamping voltage of 193V, with a peak pulse power dissipation of 400W (10/1000µs waveform). The device can handle a peak pulse current of 2.1A and offers a fast response time of less than 1ps from 0V to VBR min.
This TVS diode is housed in a compact DO-214AC (SMA) surface mount package, suitable for automated assembly. It operates over a wide temperature range of -65°C to 150°C and has a storage range of -65°C to 175°C. The junction is glass passivated for reliability, and the device is halogen free with matte tin lead-free plating.
Typical applications include protection of I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The SMAJ120A also provides ESD protection per IEC 61000-4-2 (30kV air/contact) and EFT protection per IEC 61000-4-4.
