1N5252B

Single Zener Diodes Overview

The Microchip Technology 1N5252B is a single Zener diode housed in a DO-35 glass axial-lead package. It provides a nominal Zener voltage of 24 V with a tolerance of ±5%. The device dissipates up to 500 mW at 25°C and operates within a temperature range of -65°C to +175°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 33 Ohms, and a positive voltage temperature coefficient of +0.088 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• Capable of regulating voltage across a broad operating current and temperature range
• Inherently radiation hard per MicroNote 050
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' confirms the required ±5% voltage tolerance. Confirm the package type matches the DO-35 axial lead requirement. Ensure the manufacturer source aligns with project specifications, as this component originates from the Microsemi Scottsdale Division product line.

Single Zener Diodes Selection Notes

Select this component when a precise 24 V reference with tight tolerance is needed in an axial package. Consider the positive temperature coefficient for thermal compensation requirements. Verify that the 500 mW power dissipation rating meets the circuit's thermal load without excessive derating.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 volts. The 'B' suffix specifically denotes a standard voltage tolerance of plus or minus 5%.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF style package. RoHS compliant devices can be identified by adding the 'e3' suffix to the part number.
