3 Description
The TSDxx are a family of unidirectional TVS
protection diodes designed for clamping harmful
transients such as ESD and surge. The TSDxx is
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 is an excellent TVS
diode to protect both data and power lines in many
different applications.
The TSDxx is offered in the industry standard, leaded
SOD-323 package to enable easy solderability.
