1N5234B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5234B/TR is a 6.2 V Zener diode with a ±5% voltage tolerance, housed in a DO-35 glass axial-lead package. It dissipates up to 0.5 W at 25°C and operates from -65°C to +175°C. The device features a maximum reverse leakage current of 5 µA at 5.0 V and a dynamic impedance of 7.0 Ω at a test current of 20 mA. It is supplied in tape-and-reel packaging.

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 reliable mounting
• Offers minimal capacitance characteristics suitable for high-frequency applications

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection networks
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet originates from Microsemi while the part number suffix indicates Microchip distribution. Confirm that the TR suffix corresponds to the required tape-and-reel packaging format for your automated assembly process before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 6.2 V reference with tight ±5% tolerance is required. Ensure the circuit design accommodates the 0.5 W power dissipation limit and verify that the DO-35 through-hole form factor aligns with the target PCB layout constraints.

Single Zener Diodes Part Context

This component belongs to the widely used 1N5221 through 1N5281B series of 0.5 W glass Zener diodes. The 'B' suffix specifically denotes a standard 5% voltage tolerance, distinguishing it from wider tolerance variants within the same family.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' 1N5234B equivalents or the 1N5234 without the B suffix if a 10% tolerance is acceptable. Surface mount alternatives are available in the MLL5221 to MLL5281B MELF series.
