RF01012 Rev A, August 2010 High Reliability Product Group Page 1 of 5
DEVICES MRT100KP40A thru MRT100KP400CA, e3
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.
Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B
RoHS Compliant devices available by adding “e3” suffix
3σ lot norm screening performed on Standby Current ID
Protection from high power switching transients, induced RF, and lightning threats with
comparatively small package size (0.25 inch diameter)
Protection from ESD and EFT per IEC61000-4-2 and IEC61000-4-4
