1N5227

Single Zener Diodes Overview

The Microchip Technology 1N5227 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.6 V with a maximum power dissipation of 500 mW. The component utilizes a DO-35 axial leaded package and supports through-hole mounting. Electrical characteristics include a reverse leakage current of 15 µA at 1 V, a Zener impedance of 24 Ohms, and a forward voltage of 1.5 V at 200 mA. The device operates within a junction temperature range of -65°C to +175°C.

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix (e.g., A, B, C) required for your design, as the base part number covers multiple variants with different voltage accuracies. Confirm RoHS compliance status, as commercial versions may differ from military specifications. Ensure the selected package matches your PCB footprint requirements before ordering.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference is needed in a standard axial package. Consider the 5% or tighter tolerance options based on circuit precision requirements. Evaluate the thermal resistance and power derating curves if operating near the maximum junction temperature limit of 175°C.

Single Zener Diodes Part Context

This component belongs to the JEDEC registered 1N5221 through 1N5281 series of 0.5 W Zener voltage regulators. The series provides an extensive selection of voltages ranging from 2.4 V to 200 V. These devices are widely used in industrial and commercial electronics requiring reliable voltage clamping and regulation.

Single Zener Diodes Replacement Considerations

Direct equivalents include other manufacturers' 1N5227B parts. Surface mount alternatives exist in the 1N5221BUR-1 series for space-constrained designs. Verify pinout compatibility and thermal performance when substituting with non-Microchip components.
