M5KP40CA [Microchip]

These high-reliability transient voltage suppressors are available in either unidirectional or bidirectional versions with RoHS compliant options. They protect against secondary lightning effects per IEC61000-4-5, voltage pulses from inductive switching, and induced RFI. With virtually instantaneous response time, they also provide ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4. The series suppresses transients up to 5,000 watts at 10/1000 µs and features enhanced reliability screening options in reference to MIL-PRF-19500. They are economical axial-lead plastic encapsulated devices for thru-hole mounting.
