1N5239B_T50A

Single Zener Diodes Overview

The onsemi 1N5239B_T50A is a single silicon Zener diode with a nominal voltage of 9.1 V and a tolerance of 5%. It features a maximum power dissipation of 500 mW and operates in the -65°C to +200°C temperature range. The device utilizes a DO-35 axial leaded package for through-hole mounting. Key electrical characteristics include a test current of 20 mA, a maximum reverse leakage current of 3 µA, and a Zener impedance of 10 Ohms at the specified test conditions.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via avalanche breakdown in a unidirectional configuration
• Utilizes hermetically sealed glass construction for environmental protection
• Supports high thermal stability with an extended operating temperature range up to 200°C

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50A against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Single Zener Diodes Selection Notes

Select this component when a reliable 9.1 V reference is needed in a through-hole design. The 5% tolerance suits applications where moderate precision is acceptable. Consider the 500 mW power rating for thermal management in the final enclosure. Verify that the DO-35 package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This component belongs to the standard 1N52xx series of Zener diodes manufactured by onsemi. These devices are widely used in industrial and consumer electronics for basic voltage clamping and reference functions. The 1N5239B variant specifically targets the 9.1 V market segment within the broader family of low-power regulators.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the MMBZ5239B for surface-mount needs or equivalents from other manufacturers like Microchip and Central Semiconductor, provided they match the 9.1 V, 500 mW, and DO-35 package specifications.
