COMPANY PROFILE
In business more than 25 years, ProTek Devices™ is a privately held semiconductor company. The company oers a product line of overvoltage pro-
tecon and overcurrent protecon components. These include transient voltage suppressor array (TVS arrays) avalanche breakdown diode, steering
diode TVS array and electronics SMD chip fuses. These components deliver circuit protecon in electronic systems from numerous overvoltage and
overcurrent events. They include lightning; electrostac discharge (ESD); nuclear electromagnec pulses (NEMP); inducve switching; and elec-
tromagnec interference (EMI) / radio frequency interference (RFI). ProTek Devices also oers LED wafer die for ESD protecon and related high
frequency products. ProTek Devices is ISO 9001:2015 cered.
