Overview
The Microchip Technology 1N4751AP/TR8 is a silicon planar Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 30V with a tolerance of ±5%. The device is rated for a power dissipation of 1W and operates within an ambient temperature range of -65°C to +150°C. Packaged in the DO-204AL (DO-41) axial leaded format, it utilizes a hermetic glass seal construction. This component is supplied in tape and reel packaging for automated surface mount or through-hole assembly processes.
Feature Summary
- Hermetically sealed glass package construction
- Silicon planar technology design
- Axial leaded configuration
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipper and clamper circuits
Procurement Notes
Verify the specific suffix 'TR8' against the manufacturer's current datasheet to confirm the exact reel quantity and packaging specifications. Ensure the part number matches the required 30V rating and ±5% tolerance. Confirm RoHS compliance status as indicated by the 'E3' suffix variant if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a stable 30V reference is required in high-power environments. The 1W power rating allows for significant current handling compared to lower-power variants. The wide operating temperature range makes it suitable for industrial applications where thermal stability is critical for maintaining precise voltage regulation.
Part Context
This part belongs to the standard 1N47xx series of Zener diodes manufactured by Microchip Technology. These components are widely used in general-purpose electronics for basic voltage clamping and regulation tasks. The DO-41 package provides a robust mechanical structure suitable for through-hole mounting on printed circuit boards.
Replacement Considerations
Compatible substitutes include the MX1N4751APTR from Microsemi and the 1N4751A-AP from Micro Commercial Components. Verify that replacement parts maintain the same 30V Zener voltage, 1W power rating, and DO-41 package dimensions.
