Overview
The Lumimax Optoelectronic Technology 1N4751A is a silicon planar Zener diode housed in a DO-41 glass package. It provides a nominal Zener voltage of 30V with a tolerance of ±5%. The device supports a maximum power dissipation of 1W and features a peak pulse power rating of 1W. Electrical characteristics include a maximum dynamic impedance of 40 Ohms and a reverse leakage current of 5 µA at 22.8V. The junction temperature reaches 200°C, while the storage range spans from -65°C to +200°C.
Feature Summary
- Glass passivated junction construction for environmental stability
- Guaranteed high-temperature soldering capability up to 260°C
- Low Zener impedance and low regulation factor for stable performance
Applications
- Voltage regulation circuits
- Reference voltage sources
- Overvoltage protection applications
Procurement Notes
Verify that the component matches the specific manufacturer designation for Lumimax Optoelectronic Technology rather than generic equivalents. Confirm the DO-41 glass package type and axial lead configuration align with board layout requirements. Ensure the ±5% tolerance specification meets circuit design constraints before finalizing procurement orders.
Selection Notes
Select this component when a 30V reference point is required within a 1W power budget. The DO-41 glass package offers robust thermal handling suitable for through-hole mounting. Consider the 40 Ohm impedance value for noise-sensitive designs where lower dynamic resistance might be necessary.
Part Context
This part belongs to the 1N47xxA series of Zener diodes manufactured by Lumimax Optoelectronic Technology. The series covers a wide voltage range from 3.3V to 75V, all sharing similar mechanical and electrical profiles. The 1N4751A specifically targets the 30V segment of this standardized lineup.
Replacement Considerations
Generic 1N4751A parts from other manufacturers may serve as substitutes if they meet the 30V, 1W, and DO-41 specifications. Verify that alternative sources provide equivalent ±5% tolerance and comparable thermal ratings.
