Overview
The Motorola 1N4745CRL is a silicon unidirectional Zener voltage regulator diode housed in a DO-41 glass package. It provides a nominal Zener voltage of 16V with a maximum power dissipation of 1W at ambient temperatures up to 50°C. The device features a tight voltage tolerance of ±2% and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum reverse leakage current of 5µA and a dynamic impedance of 16Ω, ensuring stable regulation for precision applications.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- High thermal stability with extended operating temperature range
- Tight voltage tolerance for precise regulation requirements
Applications
- Precision voltage reference circuits
- Overvoltage protection systems
- Power supply regulation modules
Procurement Notes
Verify the specific manufacturer source, as original Motorola semiconductor assets have undergone corporate restructuring. Confirm that the component meets current RoHS compliance standards if required by your design specifications. Ensure the part number suffix matches the exact tolerance and packaging configuration needed for your assembly process.
Selection Notes
Select this component when a 16V regulation point with high accuracy is required. The DO-41 through-hole package facilitates easy integration into standard PCB layouts. Consider the thermal resistance ratings for heat dissipation planning in enclosed environments.
Part Context
This component belongs to the widely recognized 1N47xx series of one-watt Zener diodes. Originally produced by Motorola Semiconductor Products Inc., these devices are now often sourced from successor entities or licensed manufacturers. The series remains a standard choice for general-purpose voltage regulation tasks.
Replacement Considerations
Compatible substitutes include the Microchip 1N4745A and Tak Cheong TC1N4745C. Verify that replacement parts maintain the same 16V nominal voltage, 1W power rating, and ±2% tolerance to ensure circuit compatibility.
