Bi-directional

Description

The SA series is designed specifically to protect sensitive electronic

equipment from voltage transients induced by lightning and other transient

voltage events.

Features

Glass passivated chip junction in DO-15 Package

Low leakage

Uni and Bidirectional unit

Excellent clamping capability

500W Peak power capability at 10 × 1000µs waveform Repetition rate

(duty cycle):0.01%

Fast response time: typically less than 1.0ps from 0 Volts to V_BRmin

Typical I_Rless than 5μA above 12V.

High Temperature soldering: 260°C/40 seconds at terminals

Typical maximum temperature coefficient ΔV_BR= 0.1% ×

V_BR@25°C× ΔT

Functional Diagram

Plastic package has Underwriters Laboratory Flammability 94V-0

Matte tin lead–free Plated

Halogen free and RoHS compliant

Typical failure mode is short from over-specified voltage or current

Whisker test is conducted based on JEDEC JESD201A per its table

4a and 4c

Bi-directional

Cathode

Anode

IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)

ESD protection of data lines in accordance with IEC 61000-4-2

(IEC801-2)

Uni-direction

EFT protection of data lines in accordance with IEC 61000-4-4

(IEC801-4)

Applications

TVS devices are ideal for the protection of I/O interfaces, V_CCbus and other

vulnerable circuits used in Telecom, Computer, Industrial and Consumer

electronic applications.
