Double diode array for switch and reverse blocking protection

 

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

The PDFN3-32 is designed to protect 24V 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°C to 100°C. The PDFN3-32 is also RoHS and REACH compliant.

Mechanical, packaging and availability information
Now available, the PDFN3-32 is a suitable 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°C-270°C.

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.
