HER108

HER108 is a GOODWORK Electronics fast-recovery diode — VRRM 1000 V, 1 A average rectified current, 30 A non-repetitive surge, 75 ns reverse-recovery time, DO-41 axial package. The fast recovery is the selection point: 75 ns recovery versus microseconds for standard rectifiers — the HER series is the default choice for high-frequency rectification and freewheeling in switching supplies. Selection advice: the HER101–HER108 family shares the DO-41 package across voltage grades (50 V to 1000 V) — pick the grade that covers your rail with margin; the HER108 is the 1000 V top grade. For 50/60 Hz mains rectification a standard 1N4007 is cheaper; use the HER108 where switching speed matters. Evidence: GOODWORK official datasheet confirms 1000 V, 1 A, 30 A IFSM, 75 ns TRR, DO-41.
