Vishay SD103B-TR is a metal-on-silicon Schottky barrier small signal diode featuring a protective PN junction guard ring. It supports a maximum continuous forward current of 200 mA and withstands peak reverse repetitive voltage of 30 V, making it suitable for precise electronic applications requiring efficient switching.
The diode's low forward voltage drop of 600 mV contributes to energy efficiency, while the peak forward surge current of 15 A enables operation under transient surges. Its DO-35 through hole package provides sturdy and easy mounting on printed circuit boards.
Operating reliably over a temperature range from -55°C to 125°C, the SD103B-TR diode exhibits minimal leakage current with a peak reverse current of only 5 μA. The fast peak reverse recovery time of 10 ns makes it ideal for high-speed switching applications.
This diode meets the stringent automotive standard AEC-Q101, ensuring suitability for automotive electronic systems. Its compact size includes a length of 55.9 mm, height of 3.9 mm, and diameter of 1.7 mm.
