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
volts to BV for unidirectional and
5.0ns for bidirectional types.
••Typical IDless than 1µA above 10V.
••High temperature : 300°C/10seconds/0.375”, (9.5mm)
soldering guaranteed lead length/5lbs., (2.3kg) tension.
Mechanical Data:
Case : JEDEC DO-15 moulded plastic over
passivated junction.
Terminals : Plated axial leads, solderable per MIL-STD-
750, Method 2026.
Polarity : Colour band denotes positive end
(cathode) except bidirectionals.
Mounting Position : Any
Devices For Bipolar Applications:
For bidirectionals use C or CA suffix for types. Electrical characteristics
apply in both directions.
