The Microsemi Corporation MPT-45C is a Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from transient overvoltages. It offers a peak pulse power dissipation of 1500 watts at a 10/1000 µs waveform.
This TVS diode series is available in both unidirectional and bidirectional configurations, providing a very low clamping factor for minimal voltage overshoot above the breakdown voltage. The working voltage range is from 5V to 45V, with a nominal voltage of 45V and a peak pulse current rating of 19A.
The MPT-45C features a fast response time, with clamping occurring in less than 100 picoseconds for unidirectional devices and less than 5 nanoseconds for bidirectional devices. It is suitable for protecting against inductive switching transients, secondary lightning effects per IEC61000-4-5, and ESD/EFT per IEC61000-4-2 and IEC61000-4-4.
Packaged in a hermetically sealed DO-13 metal package, the MPT-45C is designed for through-hole mounting. The operating temperature range is -65°C to 175°C (TJ). This component is also approved by CB, CE, cURus, and TUV, making it suitable for a wide range of applications.
