Single Zener Diodes Procurement Notes

Verify the specific suffix TR8 indicates reel packaging when confirming order details. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the manufacturer part number with official Microchip documentation to confirm availability and lead times prior to procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a precise 62 V regulation point with ±5% accuracy. The DO-41 package supports through-hole mounting, while the extended operating temperature up to 200 °C makes it suitable for harsh environments where standard silicon diodes may fail.

Single Zener Diodes Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. These components are widely used for general-purpose voltage regulation and protection. The AP designation typically denotes a specific tolerance level, while the TR8 suffix identifies the tape-and-reel packaging format for automated assembly.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N4759A from onsemi and the 1N4759ARL from NXP/Motorola. Verify that replacement parts match the 62 V Zener voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and electrical compatibility.
