• 400 W peak pulse power capability with a

10/1000

μs

waveform,

repetitive

rate

(duty cycle): 0.01 % (300 W above 91 V)

• Excellent clamping capability

• Very fast response time

• Low incremental surge resistance

• Meets MSL level 1, per J-STD-020, LF maximum peak

of 260 °C

• AEC-Q101 qualified available

- Automotive ordering code: P/NHE3 or P/NHM3

• Material categorization: for definitions of compliance

TYPICAL APPLICATIONS

Use in sensitive electronics protection against voltage

transients induced by inductive load switching and lighting

on ICs, MOSFET, signal lines of sensor units for consumer,

computer, industrial, and telecommunication.
