1N5232B

Single Zener Diodes Overview

The Fairchild Semiconductor 1N5232B is a single silicon Zener diode housed in a DO-35 glass axial-lead package. It provides a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device dissipates up to 500 mW and operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a maximum dynamic impedance of 11 Ω, a reverse leakage current of 5 µA, and a test current of 20 mA.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the manufacturer origin carefully, as the 1N5232B designation is widely produced by multiple vendors including Microchip, onsemi, and PANJIT. Confirm that the specific part number suffix matches the required package style (DO-35) and compliance standards. Ensure the selected variant meets the necessary military or industrial screening levels if applicable to the design requirements.

Single Zener Diodes Selection Notes

Select this component when a standard 5.6 V reference is needed in a through-hole axial configuration. The wide operating temperature range supports high-temperature environments. Verify that the 500 mW power dissipation rating aligns with the thermal management capabilities of the target circuit board layout.

Single Zener Diodes Part Context

This component belongs to the popular 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a broad selection of voltages from 2.4 to 200 volts in standard tolerances. These devices are commonly used in general electronic applications requiring reliable voltage clamping or referencing.

Single Zener Diodes Replacement Considerations

Equivalent parts include the Microchip 1N5232B, onsemi 1N5232B, and PANJIT 1N5232B. Cross-referencing requires confirming identical pinout, voltage tolerance, and package dimensions.
