Transient Voltage Suppressors

SA5V0(C)A - SA170(C)A

Features

• Glass passivated junction.

• 500W Peak Pulse Power capability on

10/1000 µs waveform.

• 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.

DO-15

COLOR BAND DENOTES CATHODE

ON UNIDIRECTIONAL DEVICES ONLY. NO

COLOR BAND ON BIDIRECTIONAL DEVICES.

• Typical I_Rless than 1.0 µA above 10V.

DEVICES FOR BIPOLAR APPLICATIONS

- Bidirectional types use CA suffix.

- Electrical Characteristics apply in both directions.
