Overview
The 1N5532A/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 12 V with a tolerance of ±10%. The device has a maximum power dissipation of 500 mW and operates in the DO-204AH (DO-35) axial through-hole package. The '/TR' suffix indicates it is supplied in a Tape & Reel packaging format. Key electrical characteristics include a test current of 1 mA and an impedance of 90 Ohms.
Feature Summary
- Provides stable voltage regulation at a nominal 12 V level
- Suitable for general-purpose voltage reference and protection circuits
- Available in standard axial leaded package for through-hole mounting
Applications
- Voltage regulation in low-power electronic circuits
- Clamping and protection against voltage transients
- Reference voltage sources in analog signal processing
Procurement Notes
Verify that the '/TR' suffix corresponds to the required tape and reel packaging configuration rather than bulk or individual units. Confirm the manufacturer source is authorized to ensure component authenticity and traceability. Check lot codes and date codes against project requirements for long-term supply chain stability.
Selection Notes
Select this component when a 12 V Zener voltage with 500 mW power rating is required in an axial package. Ensure the application current does not exceed the limits defined by the 500 mW dissipation capability. Consider the ±10% tolerance if tighter voltage regulation is needed, as alternative precision variants may be necessary.
Part Context
This part belongs to the standard 1N series of Zener diodes, widely used for basic voltage regulation tasks. The 1N5532A variant specifically denotes the 12 V version within this family. Microchip Technology continues production of these legacy components to support existing designs requiring through-hole axial packages.
Replacement Considerations
Compatible substitutes include other manufacturers' 1N5532A equivalents meeting the same 12 V, 500 mW, and DO-35 package specifications. Verify pinout compatibility and thermal characteristics before substitution. Cross-reference with 1N5532B for tighter tolerance options if applicable.
