The SMAJ64A is a 400W unidirectional TVS diode from Littelfuse Inc., part of the SMAJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events.
This device offers a peak pulse power dissipation of 400W at 10/1000μs waveform, with a clamping voltage of 103V at 3.9A peak pulse current. It features a standoff voltage of 64V and a unidirectional Zener configuration. The operating junction temperature range is -65°C to 150°C, with storage from -65°C to 175°C.
Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The device provides fast response time (typically less than 1ps) and low leakage current. It is also compliant with IEC 61000-4-2 ESD protection up to 30kV.
The SMAJ64A is housed in a DO-214AC (SMA) surface mount package, suitable for compact PCB layouts. It has a typical thermal resistance of 30°C/W junction to lead and 120°C/W junction to ambient.
