Taiwan Semiconductor 1 kV 3 A Surface Mount Switching Diode DO-214AB RS3M

Taiwan Semiconductor RS3M is a high-performance switching diode designed for surface mount applications in electronic circuits requiring reliable rectification up to 3 A continuous current and blocking voltages up to 1 kV. Packaged in a DO-214AB (SMC) package, this diode supports efficient surface mounting on PCBs, making it suitable for automated assembly processes used in industrial and commercial electronics manufacturing.

This single diode configuration provides switching rectification with a low forward voltage drop of 1.3 V, which minimizes power loss and heat generation in circuits. The fast peak reverse recovery time of 500 ns allows the diode to operate effectively in high-frequency switching power supplies and inverter circuits.

The RS3M diode operates over a wide temperature range from -55°C to 150°C, ensuring stability and reliability in demanding environments including industrial controls, power management, and consumer electronics. Its capability to withstand peak non-repetitive forward surge currents up to 100 A provides robustness against transient events, making it suitable for protection circuits and rectification in power supplies.

Dimensions of 7.11 mm length, 6.22 mm width, and 2.42 mm height place the component within typical surface mount form factors. With 2 pins for connection, it offers straightforward integration into circuit designs requiring Schottky or switching diodes.

This diode is commonly used in applications such as power rectifiers, voltage clamping, switching regulators, and freewheeling diodes in motor controllers and power inverters, where fast switching and high voltage blocking are critical.

The DO-214AB package is industry standard for surface mounted rectifiers ensuring compatibility with automated pick-and-place assembly. Peak reverse voltage of 1 kV supports high-voltage electronic circuits. Maximum forward current of 3 A suits medium-power applications.

Fast recovery time reduces switching losses for improved efficiency. Robust temperature range enables use in demanding industrial and automotive environments.
