Single Zener Diodes Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm packaging configuration. Ensure that the requested variant matches the required electrical tolerances and thermal ratings for the intended application environment before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 33 V Zener voltage with 500 mW power handling is required in an axial package. Consider the 58 Ohm impedance and 100 nA leakage specifications for circuit sensitivity requirements. Confirm compatibility with through-hole assembly processes and high-temperature operational limits.

Single Zener Diodes Part Context

This part belongs to the standard 1N52xx series of 0.5 W Zener diodes manufactured by Microchip Technology. The series offers a wide selection of voltages ranging from 2.4 V to 200 V in standard DO-35 or DO-7 packages. These components are widely used in general electronics for basic voltage clamping and regulation functions.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 33 V, 500 mW Zener diodes in DO-7 packages. Verify pinout compatibility and ensure equivalent electrical parameters such as impedance and leakage current are met for direct substitution.
