Littelfuse 1-Element Bi-Directional TVS Diode, 400 W, 2-Pin Surface Mount DO-214 SMAJ15CA

Littelfuse SMAJ15CA is a single-element, bi-directional transient voltage suppressor (TVS) diode rated at 400 W peak pulse power dissipation. Packaged in a 2-pin surface mount DO-214 housing, this TVS diode is engineered to protect sensitive electronic components against voltage transients caused by lightning, inductive load switching, and electrostatic discharges.

This device features a minimum breakdown voltage (Vbr) of 16.7 V and a maximum reverse standoff voltage (Vwm) of 15 V which makes it suitable for 15 V nominal system voltage applications. The clamping voltage rating of 24.4 V ensures efficient suppression of overvoltage spikes by limiting the voltage that can appear across protected circuits.

With a maximum peak pulse current (Ippm) rating of 16.4 A, the SMAJ15CA provides robust transient absorption capacity. It operates reliably within a wide temperature range from -65°C to 150°C, making it suitable for industrial, automotive, and commercial electronics applications where temperature variations are significant.

The device's low maximum reverse leakage current of 1 μA ensures minimal power loss during normal operation. The compact dimensions (4.5 mm length, 2.79 mm width, 2.087 mm height) and surface mount design allow for efficient automated assembly on PCBs with high-density circuit layouts.

Its primary applications include surge and transient voltage protection in power supplies, telecom systems, industrial controls, and automotive electronic modules. Single diode configuration designed for bi-directional transient voltage suppression.
