ON Semiconductor MURS120T3G Ultrafast Diode, 200V, 1A, DO-214AA

The MURS120T3G from ON Semiconductor is a surface mount ultrafast power rectifier designed for high voltage, high frequency rectification, freewheeling, and protection in applications where compact size and weight are critical. Its epoxy molded case with corrosion-resistant external surfaces and readily solderable terminal leads ensures durability and ease of assembly.

Featuring a high temperature glass passivated junction, this diode delivers reliable performance and a low forward voltage drop of just 875 mV, enhancing system efficiency. With a repetitive peak reverse voltage of 200 V and an average forward current of 1 A, it is well-suited for demanding power management and safety applications. The device offers a fast reverse recovery time of 35 ns and can withstand a forward surge current of up to 40 A, providing robust protection in transient conditions.

The diode comes in a compact DO-214AA (SMB) package with 2 pins, making it ideal for space-constrained surface mount designs. A clear polarity band indicates the cathode lead, simplifying installation. With a junction-to-lead thermal resistance of 13°C/W and a maximum operating temperature of 175°C, this rectifier ensures stable operation even under high thermal stress.
