DEVICES
M1.5KE6.8A thru M1.5KE400CA, e3
LEVELS
M, MA, MX, MXL
FEATURES
High reliability controlled devices with wafer fabrication and assembly lot traceability
100 % surge tested devices
Suppresses transients up to 1500 watts @ 10/1000 µs
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.
Surface mount equivalent packages are available as MSMC(G)(J)5.0A - SMC(G)(J)170CA

MAXIMUM RATINGS
Peak Pulse Power dissipation at 25 ºC: 1500 watts at 10/1000 μs (also see Figures 1, 2, and 3) with
impulse repetition rate (duty factor) of 0.01 % or less
tclamping (0 volts to VBR min.): < 100 ps theoretical for unidirectional and < 5 ns for bidirectional
Operating and Storage temperature: -65 ºC to +150 ºC
Thermal Resistance: 22 ºC/W junction to lead at 3/8 inch (10 mm) from body, or 82 ºC/W junction to
ambient when mounted on FR4 PC board with 4 mm2 copper pads (1oz) and track width 1 mm, length 25
mm
Steady-State Power dissipation: 5 watts at TL = 40 ºC, or 1.52 watts at TA = 25ºC when mounted on FR4
PC board described for thermal resistance
