Product Description
Vishay SA28A-E3/54 is a 1-element uni-directional transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits against voltage spikes and transient surges. It features a peak pulse power dissipation capacity of 500 W, making it suitable for robust transient suppression in industrial and automotive environments. Packaged in a 2-pin axial DO-204 format, this diode supports through-hole mounting, facilitating easy integration into printed circuit boards (PCBs).
The device operates with a minimum breakdown voltage of 31.1 V and a maximum reverse stand-off voltage of 28 V, with a test current of 1 mA. It can endure a maximum peak pulse current of 11 A, providing strong surge handling capability. The maximum operating temperature rating of 175°C ensures reliable performance under elevated thermal conditions encountered in harsh environments. The package dimensions are compact, with a length of 7.6 mm, width and height of 3.3 mm, and diameter of 3.6 mm.
This TVS diode complies with the automotive AEC-Q101 standard, confirming its suitability for use in automotive electronic circuits requiring transient voltage protection. Its low maximum reverse leakage current of 1 μA helps minimize power losses during normal operation. The clamping voltage of 45.4 V ensures efficient suppression of voltage spikes to safeguard downstream components.
Typical applications include protection of power lines, power supplies, data lines, and any circuitry prone to voltage transients in automotive, industrial, and commercial electronic systems. It supports scenarios requiring reliable and quick suppression of electrostatic discharge (ESD) and other fast transient surges.
