Taiwan Semiconductor 1-Element Bi-Directional TVS Diode 500 W, 2-Pin DO-15 SA28CA

Taiwan Semiconductor SA28CA is a 1-element bi-directional transient voltage suppression (TVS) diode designed for protecting sensitive electronic components from voltage spikes and surges. Featuring a peak pulse power dissipation of 500 W, this diode is housed in a compact DO-15 package with 2 pins enabling through-hole mounting and straightforward PCB integration.

This device utilizes a single diode configuration with bi-directional voltage suppression capabilities to clamp transient voltages effectively in both polarities. With a minimum breakdown voltage of 31.1 V and a maximum reverse stand-off voltage of 28 V, it ensures precise regulation against dangerous voltage levels.

The SA28CA TVS diode has a clamping voltage of 45.4 V and can handle transient currents up to 11.5 A, providing robust protection for circuits exposed to sudden voltage surges. It operates reliably over a wide temperature range from -55°C up to 175°C, making it suitable for automotive and industrial applications subjected to harsh environments.

The compact dimensions (7.6 mm length, 3.6 mm width/diameter/height) minimize board space usage while maintaining high performance. This diode meets the automotive quality standard AEC-Q101, ensuring high levels of quality, reliability, and compliance for automotive electronic systems.
