1N5244B_T50A

Single Zener Diodes Overview

The onsemi 1N5244B_T50A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 14 V with a tolerance of ±5%. The device operates in the through-hole DO-35 (DO-204AH) axial-leaded glass package. It supports a maximum power dissipation of 500 mW at 75°C and functions within an operating junction temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a dynamic impedance of 15 Ohms, and a test current of 9 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional silicon Zener junction.
• Constructed in a hermetically sealed glass axial-lead DO-35 package for corrosion resistance.
• Capable of high-temperature operation up to 200°C junction temperature.

Single Zener Diodes Applications

• Industrial voltage regulation circuits
• Commercial equipment power supplies
• Computer application reference voltages

Single Zener Diodes Procurement Notes

Verify that the specific suffix _T50A corresponds to the required bulk packaging configuration as defined by onsemi documentation. Confirm RoHS compliance status and REACH SVHC declarations against the latest manufacturer datasheet before integration into production designs.

Single Zener Diodes Selection Notes

Select this component when a standard 14 V reference with 5% tolerance is required in a through-hole form factor. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specified thermal derating requirements above 75°C ambient temperature.

Single Zener Diodes Part Context

This part belongs to the widely recognized 1N52xx series of 0.5 W Zener diodes. The 'B' suffix indicates a ±5% voltage tolerance, distinguishing it from lower precision variants. The device is JEDEC registered under the DO-204AH package outline, ensuring compatibility with standard axial-leaded mounting processes.

Single Zener Diodes Replacement Considerations

Equivalent parts include the Central Semiconductor 1N5244B TR PBFREE and Vishay 1N5244B. Verify that substitute manufacturers maintain identical DO-35 dimensions and 14 V / 500 mW specifications.
