1N5745B [Microchip]

The 1N5728B to 1N5757B series are 0.5 watt Zener voltage regulators in DO-35 glass axial-leaded packages, offering voltage regulation from 4.7V to 75V. They feature standard 5% tolerance (B suffix), with tighter tolerances of 2% (C suffix) or 1% (D suffix) available. Options include internal metallurgical bond (-1 suffix), MIL-PRF-19500 screening (MQ, MX, MV, MSP prefixes), and surface mount equivalents (UR suffix). The devices are non-sensitive to ESD, have minimal capacitance, and are inherently radiation hard. They provide flexible axial-lead mounting and operate over a broad temperature range.
