ProTek Devices Intros TVS Diode Array for Automated Factory Sensor Circuit Protection

TEMPE, Ariz. (PRWEB) September 24, 2018

ProTek Devices has introduced a TVS diode array designed for circuit protection of proximity sensors in automated factory sensory applications. The new device features a double diode array for switch protection and reverse blocking protection.

The PDFN3-32 is designed to protect 24-volt proximity sensors. It is compatible with IEC standards 61000-4-2 (ESD): air ±15kV, contact ±8kV; and 61000-4-4 (EFT): 40A, 5/50ns; and 61000-4-5 (surge): 40A, 8/20 micro seconds; and for interface with logic input types 1, 2, 3 and IEC 61131-2. This transient voltage suppressor diode array’s minimum breakdown voltage (VBR) is 34V and maximum clamping voltage is 55V at 25A, 8/20 micro seconds. The blocking diode drop forward voltage (VF) is 1.1V at 300mA and the blocking diode maximum 10ms square pulse current (IFSM) is 3A. The ambient operating temperature is -40 degrees Celsius to 100 degrees Celsius. The PDFN3-32 is also RoHS and REACH compliant.

Mechanical, Packaging and Availability Information
Now available, the PDFN3-32 is an ideal solution where board space is at a premium, as it is provided in a molded DFN-3 package. Other key mechanical characteristics include lead-free plating and a solder reflow temperature of 260-270 degrees Celsius. The device’s flammability rating is UL 94V-0. It is delivered on 8mm tape and reel, per EIA standard 481, in minimum quantities of 3,000. Pricing information and purchasing details can be had by contacting any authorized worldwide distributor, representative, or directly with ProTek Devices. These sales sources are available throughout North America, Europe, Asia, South America, and more. Full contact information for all regions can be found at the company website.
