1N5236B

Single Zener Diodes Overview

The Microchip Technology 1N5236B is a 0.5 W glass axial-lead Zener diode in the DO-35 package. It provides an 8.2 V nominal Zener voltage with a ±5% tolerance (B suffix). Electrical characteristics include a maximum reverse leakage current of 30 µA at 5.7 V, a Zener impedance of 8 Ω at IZK = 0.25 mA, and a positive temperature coefficient of +0.062 %/°C. The device operates within a temperature range of -65°C to +175°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
• Minimal capacitance suitable for high-frequency applications

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Power supply regulation

Single Zener Diodes Procurement Notes

Verify that the part number includes the B suffix to confirm the required ±5% voltage tolerance. Ensure the procurement specification matches the DO-35 glass axial-lead package type. Confirm compliance requirements such as RoHS status if applicable, noting that specific ordering suffixes may be necessary for lead-free or tape-and-reel options.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V reference is needed with tight tolerance constraints. The positive temperature coefficient must be accounted for in designs requiring stability over wide thermal ranges. Verify that the 0.5 W power dissipation rating aligns with the circuit's thermal management capabilities and derating curves.

Single Zener Diodes Part Context

This component belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a selection from 2.4 to 200 volts in standard 5% or 10% tolerances. These devices are JEDEC registered and utilize a DO-35 glass body axial-leaded package.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5236B in the DO-213AA MELF style package. DO-7 glass body axial-leaded equivalents are also offered by the manufacturer.
