Overview
The 1N4745AHR1G is a single Zener diode manufactured by Taiwan Semiconductor, designed for through-hole mounting in the DO-41 (DO-204AL) axial leaded package. It features a nominal Zener voltage of 16 V with a tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 16 Ohms at a test current of 15.5 mA. This component holds AEC-Q101 qualification for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Hermetically sealed glass construction for corrosion resistance
- Compression bonded internal design for mechanical stability
Applications
- Automotive voltage regulation circuits
- Overvoltage protection systems
- Reference voltage generation
Procurement Notes
Verify the specific suffix HR1G against official datasheets to confirm packaging format and RoHS compliance status. Confirm AEC-Q101 qualification requirements with the manufacturer prior to procurement. Ensure the DO-41 package dimensions match the target PCB footprint. Validate operating temperature ranges against system thermal constraints.
Selection Notes
Select this component when automotive-grade reliability is required alongside standard 1W Zener performance. The DO-41 package suits through-hole assembly processes. Verify that the 16 V breakdown voltage aligns with circuit design specifications. Consider the 150 °C junction temperature limit for high-thermal environments.
Part Context
This part belongs to the 1N4745AH series of 1 Watt Zener Diodes from Taiwan Semiconductor. The series offers various voltage options within the DO-41 package. The HR1G designation indicates specific manufacturing and packaging attributes distinct from bulk or other reel variants.
Replacement Considerations
Cross-reference with 1N4745A equivalents from other manufacturers such as onsemi or Microchip Technology. Verify pinout compatibility and ensure replacement parts meet the same AEC-Q101 automotive qualification if required.
