1N5247B_T50A

Single Zener Diodes Overview

The onsemi 1N5247B_T50A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 85 V with a 5% tolerance and operates within a power dissipation rating of 500 mW. The device utilizes a DO-35-2 through-hole package, measuring approximately 4.06 mm in length and 1.91 mm in width. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a Zener impedance of 330 Ohms, and a test current of 1.5 mA. It supports an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 85 V with tight 5% tolerance for precision circuits.
• Engineered for automated assembly processes using standard axial leaded packaging.
• Capable of reliable operation across extreme temperatures ranging from -65°C to +200°C.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable 85 V levels
• Overvoltage protection in industrial control systems
• Clamping applications in high-temperature electronic environments

Single Zener Diodes Procurement Notes

Verify the specific suffix T50A against official datasheets to confirm packaging format, as it may indicate Ammo Pack distribution rather than bulk. Confirm manufacturer lineage between onsemi and Fairchild, as legacy branding may appear on documentation. Ensure compliance requirements match project specifications before ordering.

Single Zener Diodes Selection Notes

Select this component when an 85 V Zener voltage is required with moderate power handling capabilities. The DO-35 package suits through-hole designs where space allows for larger footprints. Consider the high Zener impedance of 330 Ohms, which may affect regulation performance in low-current applications compared to lower-voltage variants.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of silicon Zener diodes manufactured by onsemi. The series covers a wide voltage range up to 75 V or higher depending on the specific model number. These components are widely used in general-purpose electronics for voltage stabilization and protection tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5268B parts with identical electrical ratings. Verify pinout compatibility and thermal resistance values when cross-referencing with generic equivalents from different suppliers.
