Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with automated placement equipment if reel handling is required. Cross-reference the part number with the latest datasheet revision to validate electrical tolerances and thermal ratings before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V regulation point is required within a standard axial footprint. Consider the 5% voltage tolerance and 25 Ohm impedance characteristics for circuit stability. Evaluate the 500 mW power rating against expected thermal loads to ensure safe operation within the specified temperature range without derating.

Single Zener Diodes Part Context

This component belongs to the 1N52 series of general-purpose Zener diodes manufactured by onsemi. The series offers various voltage options in standardized packages. The 1N5250B variant specifically targets the 20 V market segment, providing a balance between regulation accuracy and power handling capabilities for discrete electronic designs.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5250B equivalents meeting identical DO-35 mechanical and electrical specifications. Verify that alternative sources maintain the same 20 V nominal voltage, 5% tolerance, and 500 mW power dissipation ratings to ensure functional parity.
