Microsemi JANTXV1N3822UR-1 Silicon 1 watt zener diode Datasheet

1N3821 thru 1N3830A
1 Watt Metal Case Zener Diodes
SCOTTSDALE DIVISION
APPEARANCE
This well established zener diode series for the 1N3821 thru 1N3830A
JEDEC registration in the glass hermetic sealed DO-13 package provides a
low voltage selection for 3.3 to 7.5 volts. It is also well suited for highreliability applications where it is available in JAN, JANTX, and JANTXV
military qualifications. Higher voltages are also available in the 1N3016
thru 1N3051 series (6.8 V to 200 V) in the same package (see separate
data sheet). Microsemi also offers numerous other Zener diode products
for a variety of other packages including surface mount.

*ELECTRICAL CHARACTERISTICS @ 25oC
*JEDEC Registered Data.
NOTES: 1.
2.
3.
The JEDEC type numbers shown with suffix A have a standard tolerance of +/-5% on the nominal zener voltage. VZ measured
o
with device in thermal equilibrium in 25 C still air and mounted in test clips, ¾” from unit body. if tighter tolerance on VZ is required,
consult factory.
The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current (IZT or IZK) is
superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a sharp knee on the breakdown curve and to
eliminate unstable units. See MicroNote 202 for variation in dynamic impedance with different zener currents.
Allowance has been made for the increase in VZ due to ZZ and for the increase in junction temperature as the unit approaches
thermal equilibrium at the power dissipation of 1 watt.
