PF75

PF75 is a type of axial leaded hermetically sealed high voltage fase rectifier diode, PF75 has five unique features: The first one is low reverse recovery time. The second one is high thermal shock resistance. The third one is glass passivated for hermetic sealing. The forth one is low switching losses. The fifth one is soft,non-snap off, recovery charactersitics.

There are some absolute maximum ratings about PF75(@25 unless otherwise noted). Working reverse voltage(V_RWM) is 6000 W. Repetitive reverse voltage(V_RRM) is 7500 V. Surge reverse voltage(V_RSM) is 8000 V. Average forward current(I_F(AV) ) is 500 mA(@55 in oil). Non-Repetitive surge current(I_FSM) is 22 A(tp is 8.3mS,@V_R and Tjmax).Storage temperature range(T_STG) is -65 to +165. Operating temperature range(T_OP) is -65 to +165.Othewise, there are also some electrical charactersitics about it(@25 unless otherwise noted).Average forward current max(pcb mounted;Ta is 55)(I_F(AV) ) is 180 mA for sine wave and is 185 mA for square wave(d is 0.5).Average forward current max(unstirred oil at 55)(I_F(AV) ) is 490 mA for sine wave and is 500 mA for square wave. I²t for fusing(t is 8.3mS)max(I²t) is 2.0 A²S. Forward voltage drop max(@I_F is 25 mA , Tj is 25)(V_F) is 11.2 V.Reverse current max(I_R) is 5.0 uA(@V_RWM,Tj is 25). Reverse recovery time max(t_rr) is 350 nS(50 mA I_F,100 mA I_R, 25 mA I_RR).Junction capacitance typ(Cj) is 4.0 pF(@ V_R is 5 V and f is 1 MHz).
