1N5532D-1/TR

Overview

The Microchip Technology 1N5532D-1/TR is a single Zener diode with a nominal voltage of 12 V and a maximum power dissipation of 500 mW. It features a tight tolerance of ±1% and is housed in the DO-204AH (DO-35) axial through-hole package. The device operates within a junction temperature range of -65°C to 175°C, ensuring reliability under extreme conditions. Key electrical characteristics include a maximum impedance of 90 Ohms and a reverse leakage current of 50 nA at 10.8 V. The forward voltage is specified as 1.1 V at 200 mA.

Feature Summary

• Provides precise voltage regulation with a tight ±1% tolerance for critical circuit applications.
• Engineered for high-temperature stability with an extended operating range up to 175°C.
• Utilizes a robust glass passivated junction to ensure long-term reliability.

Applications

• Precision voltage reference circuits
• Overvoltage protection systems
• Voltage regulator designs

Procurement Notes

Verify that the suffix /TR indicates tape and reel packaging rather than bulk. Confirm the specific lot traceability requirements against the manufacturer's datasheet. Ensure the component meets MIL-PRF-19500 standards if military qualification is required. Cross-reference the exact part number with official Microchip documentation to validate availability and specifications.

Selection Notes

Select this component when a 12 V Zener diode with high precision is required. The ±1% tolerance distinguishes it from standard variants. Consider the DO-204AH package for through-hole mounting constraints. Evaluate the thermal performance to ensure it fits within the system's heat dissipation limits.

Part Context

This part belongs to the 1N5532 series of Zener diodes manufactured by Microchip Technology. It shares core electrical parameters with other variants like 1N5532D but differs in packaging and tolerance specifications. The series is designed for general-purpose voltage regulation tasks in industrial and commercial electronics.
