1N756A_T50R

Single Zener Diodes Overview

The onsemi 1N756A_T50R is a silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 8.2 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 0.5 W at 25°C, requiring derating above this temperature. It utilizes the DO-35 glass axial leaded package, suitable for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 7.4 V and a dynamic impedance of 8 Ω at the test current of 20 mA. The component operates within a junction temperature range up to +175°C and supports storage temperatures from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal 8.2 V Zener potential and ±5% tolerance.
• Constructed using silicon planar technology for reliable performance in axial packages.
• Capable of handling 0.5 W power dissipation with defined thermal derating requirements.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise DC levels.
• Overvoltage protection stages in electronic systems.
• General-purpose voltage regulation in low-power analog designs.

Single Zener Diodes Procurement Notes

Verify the specific suffix T50R against official onsemi documentation to confirm packaging configuration, as suffixes often denote tape-and-reel quantities or specific manufacturing lots. Ensure the procurement channel provides valid traceability for the DO-35 package variant. Cross-reference the part number with the manufacturer's current lifecycle status to confirm availability and compliance with RoHS directives prior to finalizing orders.

Single Zener Diodes Selection Notes

Select this component when an 8.2 V regulation point is required in a through-hole assembly. The 0.5 W power rating suits low-current applications where higher wattage devices are unnecessary. Consider the DO-35 package dimensions for PCB layout constraints. Verify that the operating environment stays within the specified thermal limits to maintain the ±5% voltage accuracy over the intended service life.

Single Zener Diodes Part Context

This part belongs to the broader family of small-signal Zener diodes commonly used for biasing and protection. The 1N756A designation typically corresponds to the 8.2 V variant within standardized series. The T50R suffix indicates a specific reel packaging format, distinguishing it from bulk or cut-tape versions. This classification aligns with industry-standard axial glass encapsulated diodes used in discrete semiconductor circuits.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N756A equivalents in DO-35 packages, such as those from Vishay or Central Semiconductor. Ensure replacement parts match the 8.2 V nominal voltage, 0.5 W power rating, and ±5% tolerance. Verify that alternative sources offer identical pin configurations and thermal characteristics for direct interchangeability.
