Union provides TVS (Transient Voltage Suppression) diodes that safeguard low voltage circuits against damage or latch-up caused by electrostatic discharge (ESD), lightning, and other destructive voltage transients. Our circuit protection devices feature low clamping voltage, low capacitance, and low leakage current. And, we meet the industry's toughest transient immunity IEC-61000 standards. Also, Union offers ESD / EMI filter protection with low pass L-C and R-C filter devices that use integrated TVS diodes. Our products replace multiple discrete EMI and RFI filter components and are available in small 2, 4, 6, 8 line packages. Our EMI filters are designed to suppress unwanted EMI-RFI signals and provide electrostatic discharge (ESD) and electromagnetic interference protection in portable electronic equipment.
