Procurement Notes

Verify the specific ordering suffix matches the required packing configuration, such as bulk boxes or paper reels, as indicated in the product documentation. Confirm that the component meets the necessary environmental compliance requirements for your manufacturing process. Ensure the requested quantity aligns with standard factory packaging multiples to avoid handling discrepancies during assembly.

Selection Notes

Select this component when a stable 47V reference point is required in low-power discrete circuits. The DO-41 package provides robust mechanical support for through-hole mounting processes. Evaluate the thermal derating curve to ensure the 1W power rating remains sufficient under expected ambient operating conditions.

Part Context

This part belongs to the 1N47xxA series of 1-Watt silicon Zener diodes manufactured by Panjit International Inc. The series covers a wide voltage range from 3.3V to 68V, utilizing a standardized DO-41 molded plastic case. These components are widely used in general-purpose electronic equipment for basic voltage clamping and regulation tasks.

Replacement Considerations

Cross-reference with other manufacturers' 1N4756A equivalents to verify pinout compatibility and electrical parameter tolerances. Ensure any substitute device maintains the same DO-41 axial lead form factor and 1W power dissipation capability.
