CE HER201 THRU HER208 datasheet describes CHENYI ELECTRONICS high efficiency rectifier diodes with reverse voltage ratings from 50 to 1000 V and a forward current of 2.0 A. It lists electrical and reliability features such as low forward voltage drop, low power loss/high efficiency, high surge current capability, high speed switching, and low leakage. Mechanical details specify a JEDEC DO-41 molded plastic case with UL94V-0 epoxy and color-banded cathode polarity. Maximum ratings are provided at 25 ambient temperature along with a detailed parameter table for VRRM/VRMS/VDC, VF, IR, surge current IFSM, reverse recovery time Trr, and typical junction capacitance CJ, plus temperature range TJ/TSTG.
