The popular 1N4728AG thru 1N4764AG glass body series of 1.0 watt

Zeners provides voltage regulation in a selection from 3.3 to 100 volts in

5% tolerances with other tighter tolerances also available as identified by

different suffix letters on the part number.

Zeners with a G suffix provide hermetic-sealed qualities and higher rated

temperature when required beyond that optionally provided in the same

size DO-41 plastic-body (P suffix) for these JEDEC part numbers. Both of

these package options are available by Microsemi including RoHS

Compliant devices with an “e3” suffix. A variety of other Zener product

offerings and packages are available by Microsemi to meet higher and

lower power or test current applications.

• JEDEC registered 1N4728A to 1N4764A

• Options for screening in accordance with MIL-PRF-

• Surface mount equivalents available as SMAJ4728A to

• Plastic body axial-leaded Zener equivalents are also

• RoHS Compliant devices available by adding “e3” suffix

• Power dissipation at 25

• Operating and Storage temperature: -65

• Thermal Resistance: 80

• Steady-State Power: 1.0 watts at T

• Forward voltage @200 mA: 1.2 volts (maximum)

• Solder Temperatures: 260

19500 for JAN, JANTX, JANTXV, and JANS are

available by adding MQ, MX, MV, or MSP prefixes

respectively to part numbers.
