Zener Voltage is the key parameter for each device type. It is specified at a particular test current applied at either thermal equilibrium (T.E.) or pulse test condition. The voltage tolerance for the device types listed is, in general, ±5%; however, for
some series, the voltage tolerance varies from device type to device type over a range of ±(5 to 8.5)%. Consult the complete data sheet to determine the exact test conditions and minimum/maximum limits for the zener voltage. Consult Application
Note AN924 regarding measurement of Zener Voltage (pulse versus thermal equilibrium). Power Ratings represent the capability of the case size listed as supplied by ON Semiconductor. These ratings may be higher than the JEDEC registration and/or
the same device types supplied by other manufacturers. V
