ISOM3-275-B-L2 is a hybrid protection component from Bourns' IsoMOV® Series that combines metal oxide varistor (MOV) and gas discharge tube (GDT) technologies into a single device. It features a maximum continuous operating voltage (MCOV) of 275 V rms (350 V dc), with low operating leakage of less than 10 µA at MCOV and nominal capacitance of 30 pF at 20 kHz. The device provides robust surge protection with a maximum clamping voltage of 50 V at 200 A and supports 3,000 operations at 15-surge ring-wave conditions and 6,000 operations at 10-surge conditions. With in-line lead configuration (L2), lead spacing of 7.5 ± 1.0 mm, and wire diameter of 0.8 ± 0.05 mm, this component is ideally suited for AC and DC power applications requiring premium performance, space savings, and extended temperature range operation with superior energy handling density.
