1.5KE Series 1500W TVS Diode | DO-201AE Axial Package for High-Energy Surge Protection
The 1.5KE Series TVS Diodes, housed in high-power DO-201AE axial packages, deliver 1500W peak pulse power (10/1000μs) with <1ns response time, ideal for harsh environments requiring protection against lightning surge and transient overvoltage. Available in unidirectional and bidirectional configurations, the series covers voltages from 6.8V to 440V with excellent clamping and repetitive surge endurance. It’s widely used in industrial equipment, VFDs, power supplies, inverters, energy meters, and telecom base stations.
1.5KE 1500W TVS Series is suitable for:
