The Littelfuse SMAJ43A is a unidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients. It utilizes Zener technology and offers a peak pulse power dissipation of 400W (10/1000µs waveform). The device features a clamping voltage of 69.4V at a peak pulse current of 5.8A, ensuring robust protection for downstream components.
This TVS diode operates over a wide temperature range of -65°C to 150°C and is available in a compact surface mount DO-214AC (SMA) package. It is RoHS3 compliant, with MSL Level 1 (unlimited) and REACH unaffected status. The typical forward surge current is 60A for an 8.3ms half sine wave.
Ideal for general purpose transient protection, the SMAJ43A is suitable for safeguarding I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic applications. Its fast response time (typically <1ps) and low leakage current (less than 1µA for VBR min>12V) make it a reliable choice for modern electronics.
