1N5534B/TR

Overview

The Microchip Technology 1N5534B/TR is a low voltage avalanche Zener diode with a nominal breakdown voltage of 14 V at a test current of 1 mA. It operates within a junction temperature range of -65 °C to +175 °C and dissipates up to 0.5 W. The device features a maximum reverse leakage current of 10 nA, a dynamic impedance of 100 Ohms, and a forward voltage of 1.1 V at 200 mA. It utilizes a hermetically sealed axial-lead glass DO-35 package and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance for high-frequency applications
• Includes internal metallurgical bond option for enhanced reliability
• Offers flexible axial-lead mounting terminals

Applications

• Voltage regulation over broad operating currents
• Protection against electrostatic discharge (ESD)
• Radiation-hardened circuit designs

Procurement Notes

Verify the specific suffix configuration to ensure compliance with required tolerance levels and qualification standards. Confirm that the tape and reel packaging matches automated assembly requirements. Cross-reference the manufacturer datasheet for derating curves and thermal resistance values before finalizing procurement specifications.

Selection Notes

Select this component when a precise 14 V reference is needed with tight voltage tolerances. Ensure the application environment supports the specified junction temperature limits. Verify that the power dissipation requirements remain within the 0.5 W steady-state rating under all operating conditions.

Part Context

This part belongs to the 1N5518 through 1N5546 series of 0.5 watt axial-leaded glass Zener Voltage Regulators. The series provides a selection from 3.3 to 33 volts with various tolerance options. The B suffix specifically denotes a standard tolerance of plus or minus 5%.

Replacement Considerations

Consult official documentation for qualified substitutes. Equivalent parts must match the 14 V nominal voltage, 0.5 W power rating, and DO-35 package dimensions.
