Single Zener Diodes Procurement Notes

Verify the specific suffix AG/TR against official Microchip documentation to confirm lead-free compliance and reel packaging specifications. Ensure the DO-41 footprint matches the target PCB design. Cross-reference the 5 µA leakage limit with system requirements to prevent performance degradation in low-current applications.

Single Zener Diodes Selection Notes

Select this component when a robust 62 V regulation point is required in high-temperature environments. The DO-41 package offers reliable through-hole mounting for industrial equipment. Consider the 125 Ohm impedance for noise-sensitive designs where lower ripple is critical compared to higher impedance alternatives.

Single Zener Diodes Part Context

This part belongs to the standard 1N47xx series of one-watt Zener diodes manufactured by Microchip Technology. It utilizes a silicon junction within a glass passivated DO-41 case. The series is widely recognized for its consistency in voltage regulation across various industrial and commercial electronic systems.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N4759A from onsemi or the 1N4759ARL from NXP/Motorola. Verify that replacement parts maintain the same 62 V rating, 1 W power dissipation, and DO-41 mechanical dimensions to ensure direct interchangeability.
