1N5532C

Overview

The Microchip Technology 1N5532C is a single silicon Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 12 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to 175°C. Key electrical parameters include a reverse leakage current of 50 nA at 10.8 V, a forward voltage of 1.1 V at 200 mA, and a maximum impedance of 90 Ohms. It is housed in the DO-204AH (DO-35) axial through-hole package.

Feature Summary

• Provides precise voltage regulation with a 12 V nominal breakdown voltage and ±2% tolerance.
• Capable of handling up to 500 mW of power dissipation in a compact glass axial package.
• Engineered for high-temperature reliability with an operational junction range extending to 175°C.

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in low-power electronic systems
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as 1N5532C/TR may exist with different packaging or compliance attributes. Confirm RoHS status directly with the manufacturer, as some listings indicate non-RoHS configurations. Ensure the required tolerance and power ratings align with the design specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring a standard 12 V Zener reference in through-hole layouts. The ±2% tolerance offers higher precision than standard commercial grades. Consider the 500 mW power rating against expected surge currents. The DO-35 package is suitable for general-purpose PCB mounting where space constraints are minimal.

Part Context

This part belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series provides various voltage options in the DO-35 package. The 1N5532C specifically targets the 12 V segment, offering a balance between precision and power handling for industrial and commercial electronics.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include 1N5532D and 1N5532D-1 from Microchip Technology. Verify that replacement parts match the 12 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
