    Products Detail

    The 1N4728AP thru 1N4764AP series are 1.0 watt Zener diodes for voltage regulation, available in a wide voltage range from 3.3V to 100V. They feature standard tolerances of ±5% (A suffix) and ±10% (no suffix), with tighter tolerances of ±2% (C suffix) and ±1% (D suffix). The devices are JEDEC registered, offer military screening options (JAN, JANTX, JANTXV, JANS) via prefix identifiers, and are available in surface mount equivalents (SMAJ and MLL series). They are RoHS compliant with an 'e3' suffix, have flexible axial-lead mounting, are non-sensitive to ESD, and are moisture classified as Level 1 (no dry pack required). The plastic package provides lower thermal resistance compared to glass-body options.

    Key Features

    • JEDEC registered 1N4728A to 1N4764A
    • Extensive voltage selection 3.3V to 100V
    • MIL-PRF-19500 screening options (JAN, JANTX, JANTXV, JANS)
    • Surface mount equivalents available
    • RoHS compliant (e3 suffix)
    • Tolerance options: ±5% (A), ±10% (no suffix), ±2% (C), ±1% (D)
