1N5532B/TR

Overview

The Microchip Technology 1N5532B/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 12 V with a 5% tolerance and a maximum power dissipation of 500 mW. The device operates within a junction temperature range of -65°C to +175°C and utilizes a DO-35 axial through-hole package. Key electrical characteristics include a maximum Zener impedance of 90 Ohms, a reverse leakage current of 50 nA at 10.8 V, and a forward voltage of 1.1 V at 200 mA.

Feature Summary

• Provides stable voltage regulation with a 12 V nominal breakdown voltage
• Supports high-temperature operation up to 175°C junction temperature
• Utilizes a standard DO-35 axial leaded package for through-hole mounting

Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection in electronic systems
• General-purpose voltage clamping applications

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm packaging configuration. The /TR suffix indicates tape and reel packaging, which differs from bulk options. Confirm RoHS compliance status and environmental declarations via the manufacturer datasheet before procurement. Ensure the ordering part number matches the required package style and testing conditions specified in the product specifications.

Selection Notes

Select this component when a 12 V Zener voltage with 5% tolerance is required for through-hole designs. The 500 mW power rating suits low-current regulation tasks. Consider the 90 Ohm impedance value for dynamic load requirements. Verify that the operating temperature range meets the system's thermal constraints. Compare against other variants in the 1N5532 series if tighter tolerances or different packaging are needed.

Part Context

This component belongs to the 1N55xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage ratings and tolerance levels for diverse regulation needs. The 1N5532 variant specifically targets the 12 V market segment. The /TR suffix denotes a specific packaging format distinct from the standard bulk or die versions found in the same family.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 1N5532D and 1N5532C variants from Microchip Technology. These alternatives share similar electrical characteristics but differ in voltage tolerance specifications. Verify compatibility with existing circuit parameters before substitution.
