of JiangyinThe ES1J is a diode, rectifier, and hyperfast 600V 1A 1.7V @ 1A 35ns DO-214AC RoHS from Pingwei of Jiangyin. It is designed to be a high-speed, high-efficiency, quarter-wave (QW) diode with low forward voltage drop and low reverse leakage. It is capable of operating at high frequency in applications such as signal processing, power supply, RF, and sensing. It features a relatively high peak inverse voltage (PIV) rating up to 600V, a respectable forward current of 1A, and a fast recovery time of 35ns. It is RoHS-compliant and comes in the standard DO-214AC footprint.
