3 Description

The TSDxx-Q1 are a family of unidirectional TVS

protection diodes designed for clamping harmful

transients such as ESD and surge. The TSDxx-Q1

are rated to dissipate ESD strikes up to ±30kV

(contact and air gap discharge) and also meets the

the maximum level specified in the IEC 61000-4-2

international standard (Level 4).

Combining the robust clamping performance and low

capacitance of these devices, TSDxx-Q1 are excellent

TVS diodes to protect both data and power lines in

many different applications.

The

TSDxx-Q1

is

offered

in

the

industry

standard, leaded SOD-323 package to enable easy

solderability.
