1N5276BDO35

Single Zener Diodes Overview

The Microsemi Corporation 1N5276BDO35 is a hermetically sealed glass axial-lead Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 150 V with a standard tolerance of ±5%. The device dissipates up to 0.5 watts at 25°C and operates within a temperature range of -65°C to +175°C. Electrical characteristics include a maximum reverse current of 10 µA at 108 V, a maximum Zener impedance of 5000 Ohms at 0.25 mA, and a forward voltage of 1.5 V maximum at 200 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• Standard ±5% voltage tolerance for reliable regulation
• Wide operating temperature range suitable for harsh environments
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' confirms the ±5% tolerance requirement. Confirm the 'DO35' designation matches the required DO-204AH axial lead package dimensions. Ensure the RoHS compliant 'e3' variant is selected if lead-free compliance is mandatory for the assembly process. Cross-reference the manufacturer part number against the distributor catalog to ensure correct sourcing from Microsemi or authorized channels.

Single Zener Diodes Selection Notes

Select this component when a precise 150 V reference is needed with tight tolerance. Consider the thermal resistance of 250 °C/W junction-to-lead when designing heat dissipation. Verify that the 5000 Ohm dynamic impedance meets the circuit's noise and stability requirements. Ensure the operating current stays within the limits defined by the power derating curve to prevent overheating.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a broad selection of voltages from 2.4 to 200 volts. The 'B' suffix specifically denotes the tighter ±5% tolerance compared to the standard A suffix (±10%). These devices are widely used in general-purpose electronic applications requiring stable voltage references.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5276B and 1N5276BTR. Surface mount equivalents are available as MLL5276B in the DO-213AA MELF package. Military screening levels can be obtained using prefixes such as MQ, MX, MV, or MSP with the '-1' suffix.
