Single Zener Diodes Overview

The Microsemi Corporation 1N5266A is a silicon Zener diode housed in a hermetically sealed glass DO-35 (DO-204AH) axial-lead package. It provides a nominal Zener voltage of 68 V with a standard tolerance of ±10%. 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 100 µA at 52 V and a maximum dynamic impedance of 230 Ω.

Single Zener Diodes Feature Summary

Hermetically sealed glass axial-lead construction for environmental stability
Inherently radiation hard per MicroNote 050
Minimal capacitance suitable for high-frequency applications
Flexible mounting terminals compatible with automated assembly

Single Zener Diodes Applications

Voltage regulation over broad operating current ranges
Reference voltage sources in electronic circuits
Protection against transient voltage spikes

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as it dictates the voltage tolerance and compliance status. Confirm that the required screening level matches the base part number or necessary prefix identifiers. Ensure the procurement specification aligns with the hermetic sealing requirements if applicable to the final assembly environment.

Single Zener Diodes Selection Notes

Select this component for applications requiring a stable 68 V reference with ±10% tolerance. Consider the thermal resistance of 250 °C/W when designing heat dissipation paths. Verify that the operating current remains within limits to maintain the specified impedance and prevent exceeding the 0.5 W power dissipation rating.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 volts. Variations in tolerance are indicated by suffix letters, while military screening levels require specific prefixes added to the part number.
