Technical Specifications

The 1SMB17A features a reverse standoff voltage (Vrwm) of 17V and a peak pulse power (Pp) of 600W. The clamping voltage (Vc) is dependent on the surge current. It has a very quick response time, usually in the picosecond range. The typical operating temperature ranges from -55°C to +150°C. As a unidirectional diode, it suppresses transient voltages in one direction only. This diode is a dependable and efficient option for shielding sensitive circuits from harmful voltage surges. Its small footprint and considerable surge capacity make it a versatile choice for various applications.
