    Products Detail

    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. These glass encapsulated 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. The series is JEDEC registered and offers options for screening in accordance with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS by adding MQ, MX, MV, or MSP prefixes. Surface mount equivalents and plastic body axial-leaded equivalents are also available. The devices regulate voltage over a broad operating current and temperature range, with extensive voltage selection from 3.3 to 100 V. They feature flexible axial-lead mounting terminals, standard voltage tolerances of ±5% (A suffix) and ±10% (no suffix), with tighter tolerances of ±2% (C suffix) and ±1% (D suffix). They are nonsensitive to ESD per MIL-STD-750 Method 1020 and have hermetically sealed glass body construction.
