**TVS Diode Array** (SPA[ ® ] Diodes) General Purpose ESD Protection - SD Series 

~~**RoHS**~~ **P** ~~**b GREEN** L I@OL_1~~ 

## SD Series 450W Discrete Un ~~idirectional TVS Diode~~ 

## ~~**Description**~~ 

The Unidirectional SD series is designed for use in electronic equipment for low speed and DC applications. It will protect any sensitive equipment from damage due to electrostatic discharge (ESD) and other transient events. 

The  SD series can safely absorb repetitive ESD strikes at ±30kV (contact discharge, IEC 61000-4-2) without performance degradation and safely dissipate 30A (SD05) of 8/20μs induced surge current (IEC61000-4-5 2[nd] edition) with very low clamping voltages.
