1N5245B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5245B/TR is a single Zener diode with a nominal voltage of 15 V and a tolerance of 5%. It operates in the DO-35 (DO-204AH) glass axial-lead package, dissipating up to 500 mW. The device features a maximum reverse leakage current of 100 nA at 10 V and a Zener impedance of 16 Ohms at a test current of 8.5 mA. It supports an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Offers minimal capacitance characteristics suitable for high-frequency applications

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise 15 V reference levels
• Overvoltage protection stages in electronic systems
• Clamping applications within signal processing paths

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging configuration, as the TR suffix indicates tape and reel delivery. Confirm compliance requirements against specific project standards, noting that standard versions may not meet RoHS directives without the e3 suffix. Ensure the selected variant aligns with the intended screening level and lead finish specifications.

Single Zener Diodes Selection Notes

Select this component when a 15 V breakdown voltage with tight 5% tolerance is required. Consider the thermal resistance and power derating curves if operating near the maximum dissipation limit. Evaluate the low leakage current and impedance parameters to ensure compatibility with sensitive circuit loads and stability requirements.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi's Scottsdale Division. The series provides a wide selection of voltages from 2.4 V to 200 V in standard DO-35 packages. These devices are JEDEC registered and offer various screening options for military and commercial applications.

Single Zener Diodes Replacement Considerations

Equivalent parts include the MSP1N5245B for hermetically sealed variants or other manufacturers' 1N5245B equivalents. Verify pinout compatibility and thermal performance before substitution.
