Overview
The Microchip Technology 1N4756AP/TR8 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 47 V with a tolerance of ±5%. The device has a maximum power dissipation of 1 W and operates within a temperature range of -65°C to +175°C. It utilizes the DO-213AB (MELF, LL41) surface-mount package and is supplied in a reel format.
Feature Summary
- Provides stable voltage regulation at a nominal 47 V output
- Supports high-temperature operation up to 175°C junction temperature
- Utilizes hermetically sealed glass MELF construction for reliability
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection in electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix TR8 against official Microchip documentation to confirm reel packaging specifications. Ensure the component meets RoHS compliance requirements if mandated by your design standards. Cross-reference the datasheet for absolute maximum ratings to prevent operational exceedance during procurement validation.
Selection Notes
Select this component when a surface-mount Zener diode with high thermal stability is required. The DO-213AB package suits automated assembly processes. Confirm that the 1 W power rating and 47 V breakdown voltage align with the circuit's load and voltage constraints before finalizing the design choice.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. The series offers various voltage options in both through-hole and surface-mount packages. The AP designation typically indicates tighter tolerance or specific testing criteria compared to standard variants within the same family.
Replacement Considerations
Consult Microchip's official substitution guide for verified equivalents. Generic replacements must match the 47 V Zener voltage, 1 W power rating, and DO-213AB package dimensions to ensure mechanical and electrical compatibility.
