Vishay 1-Element Bi-Directional TVS Diode 500 W, 2-Pin DO-15 SA24CA-E3/54

Vishay SA24CA-E3/54 is a high-performance 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed for surge protection in sensitive electronics. This device offers a peak pulse power dissipation of 500 W, making it ideal for protecting circuits against transient voltage spikes induced by inductive load switching and lightning surges.

Housed in a compact DO-15 through-hole package with dimensions of 7.6 mm length, 3.6 mm width and height, and a 3.3 mm diameter, the diode provides a robust solution with easy integration onto printed circuit boards. The bi-directional diode configuration ensures effective protection in both polarity directions, suited for AC and DC applications.

The diode features a minimum breakdown voltage (Vbr) of 26.7 V, and maximum reverse stand-off voltage (Vwm) of 24 V, with a clamping voltage (Vc) of 38.9 V during surge events. These parameters ensure that the device clamps voltage surges to safe levels, protecting downstream components and system integrity. The device operates over a wide temperature range from -55°C to 175°C, making it reliable for automotive, industrial, and commercial environments.

The TVS diode complies with the AEC-Q101 automotive standard, which certifies its suitability for demanding automotive system requirements and stringent reliability standards. It features a low maximum reverse leakage current of 1 μA, optimizing system power efficiency during normal operation.

Applications include transient voltage protection in power supplies, automotive electronics, telecommunication equipment, and other industrial electronic devices exposed to surge threats. The diode’s peak pulse current rating of 12.9 A and test current of 1 mA further support its capability to absorb transient energy safely without damage.
