1N459/A

      1N459/A is a kind of Small Signal Diode, which is measured with the device junction in the thermal equilibrium at the lead temperature (TL) 30°C ± 1°C and 3/8" lead length.
      At the temperature of at 25°C (unless otherwise specified), VRRM(Maximum Repetitive Reverse Voltage)=200V, IF(AV)(Average Rectified Forward Current)=500mA, TJ (Operating Junction Temperature)=175, TSTG(Storage Temperature Range)=-65 to +200°C, IFSM(Non-repetitive Peak Forward Surge Current Pulse Width = 1.0 second/Pulse Width =1.0 microsecond)=1.0/4.0 A, and these ratings are limiting values above which the serviceability of the diode may be impaired.The thermal features of 1N459/A are PD(Power Dissipation)=500 mW, RJA(Thermal Resistance, Junction to Ambient)=300°C/W.
      The electrical test at TC = 25°C(unless otherwise noted), VR(Breakdown Voltage)=200V, VF(Forward Voltage1N459A)=1.0V(IF = 3mA or IF = 100mA), IR(Reverse Leakage)=25nA/5µA(VR = 175V/VR = 175V, TA = 150°C), CT(Total Capacitance)=6.0 p.
