1N5968 Diode Derating Curves

1N5968 Diode Temperature-Current Derating Curve [Axial Lead]
5.6V Zener Voltage Regulator Diode.

1N5968 Temperature-Current Derating Curve, Leaded Device
1N5968 Zener Diode Derating Curves

Use the chart to determine how much to derate power [wattage] based on ambient operational temperature [with reference to component lead length]. Diode Derating Curves
The above chart details the maximum allowable power dissipation with increasing ambient temperature. Maximum operational power dissipation is achievable at 25C. However above 25C the maximum package dissipation, or power, must be reduce to insure that the 1N5968 junction temperature remains constant. The higher the ambient temperature is increased the lower the allowable 1N5968 power dissipation, as depicted in the curves.

Refer to MIL-PRF-19500/356; Semiconductor Device, Diode, Silicon, Voltage Regulator, Types 1N4954 through 1N4996, 1N5968, 1N5969, and 1N6632 through 1N6637, 1N4954US through 1N4996US, 1N5968US, 1N5969US, and 1N6632US through 1N6637US, and C and D Tolerance Suffix Devices, JAN, JANTX, JANTXV, JANS, JANHC, and JANKC, [Axial Leaded]
