1N5271BDO35

Single Zener Diodes Overview

The Microsemi Corporation 1N5271BDO35 is a single Zener diode with a nominal breakdown voltage of 100 V and a ±5% tolerance. It operates within the 1N5221 to 1N5281B series, providing a maximum power dissipation of 0.5 W at 25°C. The device utilizes a hermetically sealed glass DO-35 (DO-204AH) axial-lead package. Electrical characteristics include a maximum reverse current of 72 μA at 91 V and a maximum Zener impedance of 2600 Ω at a test current of 1.3 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify that the part number suffix matches the required specifications. The 'B' suffix indicates a standard 5% voltage tolerance. Confirm the presence of the 'e3' suffix if RoHS compliance is mandatory for the assembly process. Ensure the package type corresponds to the DO-35 form factor. Cross-reference the manufacturer's official documentation for any specific screening levels or prefix identifiers required for military-grade variants.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener reference with tight tolerance is required. The DO-35 package suits through-hole mounting configurations. Consider the thermal resistance and derating curves for high-power environments. Verify that the low leakage current and minimal capacitance meet the circuit requirements. Evaluate the radiation hardness attribute if the application involves space or nuclear environments.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi. The series covers a voltage selection from 2.4 V to 200 V. These components are JEDEC registered and available in various tolerance grades and screening levels. The series provides flexible axial-lead mounting terminals and is designed for robust performance in demanding conditions.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5271A, 1N5271C, and 1N5271D, which offer different voltage tolerances. Surface mount equivalents are available as MLL5271-1 in the DO-213AA MELF style package. Military screening options exist with prefixes such as MQ, MX, MV, or MSP.
