SPD9231B

1-Line, Bi-directional, Thyristor Surge Suppressors

Descriptions

The SPD9231B is a bi-directional TSS (Thyristor Surge

Suppressors) which can provide ESD protection for IC. It is

specifically designed to protect telecom equipments from

damaging overvoltage transients.

The SPD9231B is used to enable equipments to meet

various regulatory requirements including, ITU-T K.20, K.21

and IEC 61000-4-5

The SPD9231B is available in SMB package. Standard

products are Pb-free and Halogen-free.
