1N5230B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5230B/TR is a 4.7 V Zener diode housed in a DO-35 glass axial-lead package. It features a nominal voltage of 4.7 V at a test current of 20 mA, with a maximum reverse leakage current of 22 µA and a Zener impedance of 5.0 Ω. The device supports a power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C. The 'TR' suffix indicates tape-and-reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance for high-frequency applications
• Inherently radiation hard per MicroNote 050

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping circuits

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet originates from Microsemi while the model is listed under Microchip Technology. Confirm that the 'TR' suffix strictly denotes tape-and-reel packaging without altering electrical characteristics. Ensure compliance requirements match the source documentation provided.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V breakdown voltage with 5% tolerance is required in a through-hole axial configuration. Consider the low capacitance characteristic if signal integrity is critical. Verify thermal derating curves against the expected ambient temperature and mounting conditions on the PCB.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. These devices are JEDEC registered and available in standard 5% or 10% tolerances. The series offers an extensive selection ranging from 2.4 to 200 volts in the DO-35 package.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5230 (without B suffix) for 10% tolerance or 1N5230C/D for tighter tolerances. Surface mount equivalents are available in the MLL5221 to MLL5281B MELF style package.
