Specifications

The MMSZ15VCW has a standoff voltage of 15V, indicating the maximum voltage it can withstand without clamping. Its clamping voltage, which is the voltage it limits the transient to, is typically around 22V at a specific test current. The peak pulse power is around 200W for a 10/1000μs waveform. The operating temperature range is generally between -55°C and +150°C. The device is RoHS compliant. The low clamping voltage ensures the protected circuit sees minimum excess voltage during surge events. The fast response time is critical for quickly suppressing transient voltages, preventing them from damaging sensitive components. Its small size and surface mount design make it easy to integrate into high-density circuit boards. The unidirectional configuration offers straightforward protection in circuits with a specific polarity.

This TVS diode is a valuable component for protecting electronic circuits from the damaging effects of transient voltages. Its combination of high surge current capability, fast response time, and low clamping voltage makes it a reliable choice for a wide range of applications. Its small size and ease of installation further contribute to its practicality in modern electronic designs.
