New PSDxxHP Series TVS Components Provide Mobile Device Circuit Protection

Modern technology provides us with many conveniences, but they are very fragile when it comes to electrical surges. If the right protection is not used when it is being powered a fluctuation in the amount of electricity coming from the wall can permanently damage your device. A transient voltage suppression diode, or TVS, is designed to protect a device by moving a voltage spike away. Smartphones, tablets, laptops and battery chargers are devices that can benefit from circuit protection by TVS. The new 1000 watt PSDxxHP Series of TVS components from ProTek Devices provides electrostatic discharge (ESD), electrostatic overstress (EOS) and electrical fast transient (EFT) protection for today’s portable computing and communications devices.

The PSDxxHP series is available in different configurations designed to meet the specific needs of the device being protected. The low profile of the device saves valuable space on the printed circuit board which is a premium as manufacturers are always trying to decrease the size of their product. The unit has an approximate weight of just five mg with hardened lead-free pure-tin plating with the parts having a flammability rating of UL 94V-0.

Key features of the PSDxxHP series TVS include:

  • 1000 Watts Peak Pulse Power per Line (tp = 8/20µs)
  • Unidirectional Configuration
  • Protects One Power Port Line
  • Low Clamping Voltage
  • Available in 5V and 12V
  • RoHS Compliant and REACH Compliant

The new series has 18 different types of TVS components which provide manufacturers many different options when it comes to placing these components on the printed circuit board, whether it is on the I/O port or voltage bus. The units are designed to support different watts and voltages to accommodate a multitude of configurations for manufacturers across many different industries. Voltages from 3.3 to 36 V and wattage of 400 or 500 can be supported.

According to the company, pricing has been set between 14 to 16 cents, with minimum quantities of 3000 units.

ProTek Devices has been in business for more than 20 years producing a line of TVS devices for circuit protection across many different scenarios including nuclear electromagnetic pulses (NEMP), inductive switching, electromagnetic interference (EMI) / radio frequency interference (RFI) and other types of threats a circuit faces.
