TVS Diode Array Provides Sensor Circuit Protection

ProTek Devices’ PDFN3-32TVS diode array is designed for circuit protection of proximity sensors in automated factory sensory applications. The component features a double diode array 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.

 

The 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.
