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.
