    I(f) Average Rectified Forward Current : 3.0 A

    I (FSM) Non-repetitive Peak Forward Surge Current : 8.3 ms

    Single Half-Sine-Wave :  200 A

    T(stg) Storage Temperature Range : -55 to +150 °C

    T(j) Operating Junction Temperature : -55 to +150 °C

    P(d) Power Dissipation : 6.25 W

    R Thermal Resistance, Junction to Ambient : 20 °C/W

    VF Forward Voltage @ 3.0 A : 1.2 V

    Irr Maximum Full Load Reverse Current, Full Cycle TA = 105°C : 0.5 mA

    IR Reverse Current @ rated VR TA = 25°C TA = 100°C : 500 uA

    Total Capacitance VR = 4.0 V, f = 1.0 MHz : 30 pF

    1N4001/1N4007

    This is a simple, very common rectifier diode. Often used for reverse voltage protection, the 1N4007 is a staple for many power, DC to DC step up, and breadboard projects. 1N4007 is rated for up to 1A/1000V.
