3PF8

3PF8 is a type of axial leaded hermetically sealed high voltage fase rectifier diode which has five unique features: The first one is low reverse recovery time. The second one is avalanche capability. 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 of the 3PF8 about it(@25 unless otherwise noted). Working reverse voltage(V_RWM) is 800 W. Repetitive reverse voltage(V_RRM) is 800 V. Surge reverse voltage(V_RSM) is 900 V. Average forward current(I_F(AV) ) is 3.25 A(@55,lead length 0.375"). Non-Repetitive surge current(I_FSM) is 76 A(tp is 8.3mS,@VR and Tjmax).Storage temperature range(T_STG) is -65 to +175. Operating temperature range(T_OP) is -65 to +175.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 1.4 A for sine wave and is 1.50 A for square wave(d is 0.5).Average forward current max(T_L is 55 ;L is 3/8")(I_F(AV) ) of the 3PF8 is 3.10 A for sine wave and is 3.25 A for square wave. I2t for fusing(t is 8.3mS)max(I2t) is 24 A2S. Forward voltage drop max(@I_F is 3.0 A , Tj is 25)(V_F) is 1.3 V.Reverse current max(I_R) is 1.0 uA(@V_RWM,Tj is 25). Reverse recovery time max(trr) of the 3PF8 is 300 nS(0.5 A I_F,1.0 A I_R,recovers to 0.25 A I_RR).Junction capacitance typ(Cj) is 30 pF(@ V_R is 5 V and f is 1 MHz).

Well, this is a simple introduction to this type of 3PF8, if you want to know more about the 3PF8, please pay more attention to our web. Thanks for your attention!
