Description

The 728A is an electronic component and belongs to the IC Chips category. This series of 1.0 watt Zeners effectively regulate voltage across a wide range of operating current and temperature. They offer a selection of voltages ranging from 3.3 to 100 volts with 5% tolerances. Tighter tolerances are also available on request and are identified by different suffix letters in the part number. The Zeners are moisture classified as Level 1 and do not require a dry pack. This model is also available in various military screening levels, thanks to the prefix identifier, for example, adding MQ, MX, MV or MSP prefix to part numbers to get screening as per MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS. The plastic molded Zeners with a P suffix boast a lower thermal resistance compared to the glass-body (G suffix) option for the same JEDEC part numbers. You can find the 728A and other Zener products by Microsemi available as RoHS Compliant devices.
