Feature Summary

• Provides stable voltage regulation using silicon planar technology
• Features hermetically sealed glass construction for environmental protection
• Supports high operating temperatures up to 200 °C

Applications

• Voltage stabilization circuits
• Clipping and clamping applications
• Reference voltage sources

Procurement Notes

Verify the manufacturer designation on the component marking to confirm Microchip Technology origin, as this part number is also utilized by other vendors such as onsemi and Motorola. Ensure the specific suffix matches the required package style, as variations exist between standard DO-41 and surface mount configurations like DO-213AA. Cross-reference datasheets from different suppliers to confirm exact electrical tolerances and testing conditions before procurement.

Selection Notes

Select this component when a precise 62 V reference is required in through-hole designs. The 1 W power rating allows for moderate current handling in regulator topologies. Consider the ±5% voltage tolerance for circuit precision requirements. Verify that the DO-41 package dimensions fit the target PCB layout constraints and that the thermal management strategy supports the specified power dissipation limits under worst-case ambient conditions.

Part Context

This component belongs to the widely recognized 1N47xx series of Zener diodes, which are standard industry references for low-to-medium power voltage regulation. The 'AG' suffix typically denotes specific manufacturing lot or revision details within Microchip's portfolio. These devices are foundational discrete semiconductors used across various electronic systems requiring reliable DC voltage referencing.

Replacement Considerations

The 1N4759A (onsemi) and 1N4759ARL (Motorola/NXP) are functionally equivalent parts sharing the same 62 V, 1 W, DO-41 specifications. Verify pinout compatibility and physical dimensions before substitution.
