Overview
The Microchip Technology 1N4752AP/TR8 is a silicon Zener diode housed in the DO-41 (DO-204AL) axial through-hole package. It provides a nominal Zener voltage of 33V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 1W and operates within a temperature range of -65°C to +150°C. This component is supplied in tape and reel packaging, facilitating automated surface or through-hole mounting processes.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Utilizes a plastic DO-41 axial leaded package for reliable through-hole integration
- Features a single unidirectional silicon junction configuration
Applications
- Voltage regulation circuits requiring stable reference levels
- Overvoltage protection stages in electronic systems
- Clamping applications for transient suppression
Procurement Notes
Verify the specific suffix TR8 confirms the tape and reel packaging format required for your assembly line. Confirm that the standard ±5% tolerance meets your circuit design specifications. Ensure the DO-41 package dimensions align with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a 33V regulation point is required in a through-hole design. Consider the 1W power rating against expected thermal loads. Verify compatibility with existing manufacturing processes for axial lead components compared to surface mount alternatives.
Part Context
This part belongs to the widely used 1N47xx series of 1-watt Zener diodes. The 'A' prefix typically denotes the standard ±5% tolerance variant. The 'TR8' suffix indicates the specific reel quantity and packaging style provided by the manufacturer for high-volume production environments.
Replacement Considerations
Surface mount equivalents include the SMAJ4752A and MLL4752A series. Other manufacturers produce direct JEDEC-compatible replacements such as the 1N4752A from various suppliers. Verify pinout and thermal characteristics when substituting.
