DEVICES FOR BIDIRECTION APPLICATIONS
For bidirectional devices use CA suffix (e.g. 1.5SMC220CA).
Electrical characteristics apply in both directions.
FEATURES
• Low profile package
• Ideal for automated placement
• Glass passivated chip junction
• Available in unidirectional and bidirectional
• 1500 W peak pulse power capability with a
10/1000 μs waveform, repetitive rate
(duty cycle): 0.01 %
• 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: base 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 lightning
on ICs, MOSFET, signal lines of sensor units for consumer,
computer, industrial, automotive, and telecommunication.
