1N5234B

Single Zener Diodes Overview

The Microchip Technology 1N5234B is a 0.5 W glass axial-lead Zener diode in the DO-35 package. It provides a nominal Zener voltage of 6.2 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 5 µA at 4.8 V. Electrical characteristics include a test current of 20 mA, a maximum Zener impedance of 7.0 Ω at 0.25 mA, and a positive voltage temperature coefficient of +0.045 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for reliable operation
• Regulates voltage across a broad operating current and temperature range
• Minimal capacitance suitable for high-frequency applications
• Inherently radiation hard per MicroNote 050

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet identifies Microsemi while branding may indicate Microchip Technology. Confirm RoHS compliance status, as standard versions are non-compliant while 'e3' suffixes denote compliance. Ensure the ordering suffix matches the required tolerance level and screening specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 6.2 V reference is required in a through-hole axial configuration. The B suffix guarantees a tighter 5% voltage tolerance compared to the A suffix. Consider the thermal resistance and derating requirements if operating near the maximum power dissipation limit or elevated temperatures.

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 V to 200 V in the JEDEC registered DO-35 package. Variations exist with different tolerance suffixes and military screening prefixes.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5234 (±20% tolerance) and 1N5234A (±10% tolerance). Surface mount equivalents are available in the MLL5234 MELF package.
