3 Description
The TSDxx are a family of unidirectional TVS
protection diodes designed for clamping harmful
transients such as ESD and surge. The TSDxx
devices are rated to dissipate ESD strikes up to
±30kV (contact and air gap discharge) and also meets
the maximum level specified in the IEC 61000-4-2
international standard (Level 4).
Combining the robust clamping performance and low
capacitance of this device, TSDxx are excellent TVS
diodes to protect both data and power lines in many
different applications.
The TSDxx family is offered in the industry
standard, leaded SOD-323 package to enable easy
solderability.
