Single Zener Diodes Procurement Notes

Verify the specific suffix _T50A against official datasheets to confirm packaging details, as standard 1N5256B variants may differ in reel or bulk configuration. Ensure compatibility with existing board layouts for DO-35 through-hole mounting. Cross-reference manufacturer documentation for any recent product change notices affecting pinout or material composition before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 30V regulation point is required with moderate precision. The DO-35 package suits designs prioritizing through-hole assembly over surface mount constraints. Consider the 500 mW power rating to ensure adequate thermal headroom under continuous load conditions. Evaluate the 49 Ohm impedance if signal integrity in dynamic regulation scenarios is critical.

Single Zener Diodes Part Context

This part belongs to the 1N5256 series of Zener diodes manufactured by onsemi. The series offers various voltage ratings within the same physical footprint, allowing for design flexibility. The 1N5256B designation specifically indicates the 30V variant with 5% tolerance, distinguishing it from other voltages in the family while maintaining consistent thermal and mechanical characteristics.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5256B (bulk) and MMSZ5256BT3G (SMD SOD-123). Verify that replacement packages match the PCB mounting requirements. Ensure equivalent voltage and power ratings are maintained during substitution to preserve circuit functionality.
