Additional Information


Voltage Regulator Zener Diodes

This 5 Watt Zener Diode has tight limits and better operating characteristics that reflect the superior capabilities of silicon-oxide-passivated junctions. The transfer-molded plastic package provides protection in most environmental conditions.

Leads: Axial, Readily Solderable
Finish: External Surfaces Corrosion Resistant
Polarity: Cathode indicated by Band

Max. Ratings:
DC Power Dissipation: 5W
(TL = 75°C, Lead Length = 3/8")
Derated above 75°C: 40mW/°C
Operating & Storage Temperature: -65°C to 200°C

Electrical Characteristics (TA=25°C unless otherwise noted, VF=1.2V max., IF=200mA)
Nominal Zener Voltage: 20V nom. @ 65mA
Max. Zener Impedance: 3 ohms @ 65mA
Max. Zener Knee impedance: 75 ohms @ 1mA
(Test conditions for zener voltage and impedance are as follows: IZ is applied 40 ± 10 ms prior to reading. Mounting contacts are located 3/8, to 1/2, from the inside edge of mounting clips to the body of the diode. (TA = 25°C +8, –2°C))
Max. Reverse Leakage Current: 0.5µA @ 15.2V
Max. Surge Current: 5.1A
(Surge current is specified as the maximum allowable peak, non-recurrent square-wave current with a pulse width, PW, of 8.3 ms)
Max. Voltage Regulation: 0.4V
(VZ measurements are made at 10% and then at 50% of the IZ max value listed in the electrical characteristics table. The test current time duration for each VZ measurement is 40 ± 10 ms. (TA = 25°C +8, –2°C))
Max. Regulator Current: 237mA
