1N5244B-TP

Single Zener Diodes Overview

The MCC 1N5244B-TP is a single Zener diode with a nominal voltage of 14 V and a maximum DC power dissipation of 500 mW. It features a 5% tolerance on the Zener voltage, a test current of 9.0 mA, and a maximum Zener impedance of 15 Ohms at the test current. The device has a maximum reverse leakage current of 0.1 µA and a positive temperature coefficient of +0.082 %/°C. It operates within an ambient temperature range of -55°C to +150°C and utilizes a DO-35 glass axial package.

Single Zener Diodes Feature Summary

• Utilizes a glass axial package for high-temperature soldering capability up to 260°C for 10 seconds.
• Provides stable voltage regulation with a defined positive temperature coefficient above 6.2 V breakdown.
• Designed for general-purpose voltage reference and protection applications in through-hole circuits.

Single Zener Diodes Applications

• Voltage regulation in low-power electronic circuits
• Voltage reference sources for analog signal processing
• Overvoltage protection for sensitive semiconductor components

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors to avoid counterfeit parts. Confirm that the specific ordering suffix matches the required packaging format, such as tape and reel or bulk, as these affect handling procedures. Ensure compliance with RoHS directives and check for lead-in-glass exemptions if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a precise 14 V reference is required with tight 5% tolerance limits. Consider the 500 mW power rating and thermal derating characteristics for high-temperature environments. Evaluate the DO-35 package dimensions against available board space and ensure the operating temperature range meets the system's environmental requirements.

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 similar electrical characteristics and physical dimensions. The 'B' suffix specifically denotes a 5% tolerance on the nominal Zener voltage, distinguishing it from tighter tolerance variants.

Single Zener Diodes Replacement Considerations

Public confirmed substitute part numbers: 1N5244B (onsemi), MMSZ5244B-TP (MCC). Verify pinout compatibility and thermal resistance values before substitution.

Single Zener Diodes FAQ

What is the temperature coefficient for the 1N5244B-TP?

The temperature coefficient is +0.082 %/°C, measured at the rated test current with temperatures ranging from 25°C to 125°C.

How does the 'B' suffix affect the specifications?

The 'B' suffix indicates a 5% tolerance on the nominal Zener voltage, ensuring the actual breakdown voltage remains within ±5% of the 14 V nominal value.
