1N5252A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5252A/TR is a Zener diode with a nominal voltage of 24V and a tolerance of ±10%. It operates in the DO-35 (DO-204AH) glass axial-lead package. The device provides a maximum power dissipation of 0.5 watts at 25°C, derating to 0.48W on an FR4 PCB. Electrical characteristics include a test current of 5.2 mA, a maximum reverse current of 17 µA at 19V, and a maximum Zener impedance of 17 Ohms at 0.25 mA. It supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• Inherently radiation hard per MicroNote 050
• Non-sensitive to electrostatic discharge
• Minimal capacitance across the operating range

Single Zener Diodes Applications

• Voltage regulation over broad operating currents
• Temperature compensation circuits
• Reference voltage sources

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape and reel packaging as specified in the datasheet. Confirm RoHS compliance status by checking for the 'e3' suffix, as standard versions may differ. Ensure the component matches the specific JEDEC registration requirements for the 1N5252 type number before integration into production.

Single Zener Diodes Selection Notes

Select this component when a 24V Zener reference with ±10% tolerance is required. Consider the thermal resistance of 250°C/W junction-to-lead for heat management. Verify that the 0.5W power rating aligns with the circuit's steady-state power dissipation needs under expected ambient conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5-watt Zener Voltage Regulators. The series offers voltages from 2.4V to 200V with various tolerance options identified by suffix letters. The 1N5252 specifically targets the 24V segment within this extensive lineup of glass axial-leaded devices.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5251A and 1N5253A, provided they match the 24V specification and package constraints.
