1N5247B-TP

Single Zener Diodes Overview

The MCC 1N5247B-TP is a unidirectional silicon Zener diode housed in a DO-35 glass axial package. It provides a nominal Zener voltage of 17 V with a 5% tolerance, tested at a current of 7.4 mA. The device supports a DC power dissipation of 500 mW and operates within an ambient temperature range of -55°C to +150°C. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 13 V, a Zener impedance of 19 Ohms at the test current, and a positive temperature coefficient of +0.084 %/°C.

Single Zener Diodes Feature Summary

• Utilizes a glass encapsulation for high-temperature soldering stability up to 260°C.
• Features a standard DO-35 axial leaded package suitable for through-hole mounting.
• Includes cathode band marking for correct polarity identification.

Single Zener Diodes Applications

• Voltage regulation in low-power electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in analog signal processing

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit parts are prevalent; unauthorized sources lack traceability and quality assurance. Confirm that the ordering suffix matches the required packaging format (e.g., TP for Tape & Reel) before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 17 V reference is required in a compact axial package. Ensure the circuit design accommodates the 500 mW power dissipation limit and applies appropriate derating above 50°C. Verify that the operating environment remains within the specified -55°C to +150°C temperature range for reliable performance.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V, all sharing identical physical dimensions and thermal characteristics while varying in specific electrical breakdown values.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5247B equivalents. Verify that substitute parts match the 17 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
