FEATURES
Plastic package.
Glass passivated chip junction.
500W Peak Pulse Power capability on 10/1000µs waveform.
Excellent clamping capability.
Repetition rate (duty cycle): 0.01%.
Low incremental surge resistance.
Fast response time: typically less than 1.0ps from 0 volt to BV for
Unidirectional and 5.0ns for Bidirectional types.
Typical IR less than 1µA above 10V.
DO-204AC/DO-15
High temperature soldering guaranteed: 265°C/10 seconds/.375",
(9.5mm) lead length, 5lbs, (2.3kg) tension.
MECHANICAL DATA
Case: JEDEC DO-15 Molded plastic over glass passivated junction.
Terminals: Plated Axial leads, solderable per MIL-STD-750, Method 2026.
Polarity: Color band denotes cathode except Bidirectional.
Mounting Position: Any.
Weight: 0.015 ounce, 0.4ꢀgrams.
DEVICES FOR BIPOLAR APPLICATION
For Bidirectional use C or CA suffix for type SA5.0 through type SA220 (e.g. SA5.0C, SA220CA);
Electrical characteristics apply in both directions.
MAXIMUM RATINGS AND CHARACTERISTICS
Ratings at 25ć ambient temperature unless otherwise specified.
