1N5244B (DO-35)

Single Zener Diodes Overview

The Microsemi Corporation 1N5244B (DO-35) is a silicon Zener diode with a nominal voltage of 14 V and a maximum power dissipation of 0.5 W at 25°C. It features a DO-35 glass axial-lead package, a standard tolerance of ±5% indicated by the 'B' suffix, and a test current of 9.0 mA. The device operates within a temperature range of -65°C to +175°C, has a maximum reverse leakage current of 10 µA at 10 V, and exhibits a maximum Zener impedance of 15 Ω.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for reliable operation in harsh environments
• Voltage regulation capability across a broad operating current and temperature range
• Inherently radiation hard design suitable for demanding applications

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required JEDEC registration and tolerance suffix. Confirm compliance requirements such as RoHS status if applicable, noting that the base part number may differ from lead-free variants. Ensure the supplier provides documentation confirming the hermetic seal integrity and adherence to MIL-PRF-19500 screening levels if military-grade specifications are mandated for the project.

Single Zener Diodes Selection Notes

Select this component when a precise 14 V regulation point is needed within a low-power environment. The DO-35 package facilitates through-hole mounting on printed circuit boards. Consider the thermal resistance characteristics and derating curves if the ambient temperature exceeds standard limits or if steady-state power dissipation approaches the maximum rating.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages ranging from 2.4 to 200 volts. These components are widely recognized for their robust performance in general-purpose voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5244B devices meeting the same electrical specifications. Cross-referencing should verify package dimensions, pinout polarity, and thermal characteristics to ensure mechanical and functional compatibility.
