Product Description
Littelfuse SMAJ24CA is a 1-element bi-directional transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from damage caused by transient voltage events such as lightning surges and electrical switching.
This semiconductor device features a peak pulse power dissipation rating of 400 W and is housed in a compact 2-pin DO-214 surface mount package. Its low profile and built-in strain relief allow for optimized board space in modern electronic designs.
The diode has a minimum breakdown voltage of 29.5 V and a maximum reverse stand-off voltage of 24 V, providing reliable protection and excellent clamping voltage of 38.9 V to limit voltage spikes effectively.
With a fast response time typically less than 1.0 picoseconds, the SMAJ24CA offers rapid transient suppression suitable for industrial, laboratory, telecom, manufacturing, and commercial electronic applications. It operates reliably over a wide temperature range from -65°C to 150°C, endorsing durability in harsh operating conditions.
Additional product benefits include a low incremental surge resistance, very low reverse leakage current (1 μA), glass passivated junctions, and compliance with halogen-free standards, supporting environmentally responsible manufacturing.
Package dimensions measure 4.6 mm length, 2.79 mm width, and 2.08 mm height, making the diode highly suitable for space-constrained mounting applications. The device features ESD protection and is rated for high temperature soldering at 250°C for 10 seconds.
