FEATURES
.
.
.
.
.
.
High reliability controlled devices with wafer fabrication and assembly lot traceability
100 % surge tested devices
Suppresses transients up to 100 kW @ 6.4/69 µs
Fast response with less than 5ns turn-on time
Preferred 100kW TVS for aircraft power bus protection
Optional upscreening available by replacing the M prefix with MA, MX or MXL. These prefixes
specify various screening and conformance inspection options based on MIL-PRF-19500.
Refer to MicroNote 129 for more details on the screening options.
