Procurement Notes

Verify the specific manufacturer datasheet for the 1N2995A to confirm all electrical parameters, particularly regarding leakage current and impedance values, as these can vary between different production batches or manufacturers. Ensure that the selected component meets the required thermal and voltage specifications for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a 75 V Zener voltage is required in a compact axial package. Consider the 500 mW power rating and the 10% voltage tolerance during circuit design. Evaluate the maximum operating temperature of 175 °C against the environmental conditions of the target system to ensure reliable long-term performance under varying thermal loads.

Part Context

The 1N2995A belongs to the standard 1N series of Zener diodes manufactured by Microchip Technology. This series is widely recognized for its reliability in discrete semiconductor applications. The component serves as a fundamental building block for analog and digital circuits requiring precise voltage clamping or reference levels within the specified power and temperature constraints.

Replacement Considerations

Cross-reference with other manufacturers' 1N2995A equivalents to verify pinout compatibility and parameter matching. Ensure that any substitute part maintains the same DO-35 package style and meets or exceeds the 500 mW power dissipation and 75 V Zener voltage requirements.
