1N5230A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5230A/TR is a 500 mW glass axial-lead Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 30 V with a 10% tolerance, tested at 4.2 mA. Key electrical parameters include a maximum reverse current of 50 µA at 20 V and a Zener impedance of 49 Ω at 0.25 mA. The device operates within a temperature range of -65°C to +175°C and features a negative voltage temperature coefficient of +0.091 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetically sealed glass axial-lead construction for durability
• Inherently radiation hard per MicroNote 050 specifications

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging per EIA-296 standards. Confirm RoHS compliance status by checking for the 'e3' suffix if required. Ensure the manufacturer designation aligns with current Microchip or Microsemi corporate structures. Validate that the component meets all JEDEC registration requirements for the 1N5230 series.

Single Zener Diodes Selection Notes

Select this component when a 30 V Zener voltage with 10% tolerance is required. The DO-35 through-hole package suits standard PCB mounting. Consider the 500 mW power dissipation limit and derating curves for thermal management. Verify compatibility with circuit test currents near the specified 4.2 mA for optimal impedance performance.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection from 2.4 to 200 volts. Standard tolerances are identified by suffix letters, with 'A' denoting 10% and 'B' denoting 5%. These devices are widely used in industrial and commercial applications requiring reliable voltage clamping.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5230A variants in the DO-35 package. Cross-reference with 1N5230B for tighter 5% tolerance if needed. Surface mount equivalents are available as MLL5230 in the DO-213AA MELF style.
