Single Zener Diodes Procurement Notes

Verify the specific suffix T50R against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure compliance with RoHS directives and REACH SVHC requirements as stated in the datasheet. Confirm that the DO-35 through-hole package aligns with PCB layout constraints. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 17 V reference is required with tight 5% tolerance. The 500 mW power rating suits low-current regulation tasks. The wide operating temperature range makes it suitable for harsh environments. Verify that the axial leaded form factor fits the mechanical design. Consider the Zener impedance value for dynamic load regulation requirements in the target application circuit.

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 stabilization. The 1N5247B variant specifically targets the 17 V segment of the series. The T50R suffix typically indicates a specific bulk or reel packaging configuration defined by the manufacturer.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5247B from other manufacturers such as Vishay or Fairchild, provided they meet the same 17 V, 500 mW, and DO-35 package specifications. Ensure equivalent electrical parameters like Zener impedance and leakage current are matched for critical applications.
