Features
•Glass passivated junction.
•1500W Peak Pulse Power capability
at 1.0 ms.
•Excellent clamping capability.
•Low incremental surge resistance.
•Fast response time; typically less
than 1.0 ps from 0 volts to BV for
unidirectional and 5.0 ns for
bidirectional.
•T ypical IR less than 1.0 µA above 10V.
DEVICES FOR BIPOLAR APPLICA TIONS
- Bidirectional types use CA suffix.
- Electrical Characteristics apply in both directions.
