Overview
The 1N4752G R0G is a 1W Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 33V with a tolerance of ±5%. The device utilizes a DO-41 axial leaded package and operates within a temperature range of -55°C to +150°C. Key electrical specifications include a maximum dynamic impedance of 45Ω at the test current of 7.5mA. The component is RoHS compliant and hermetically sealed in glass.
Feature Summary
- Hermetically sealed glass construction for corrosion resistance
- Compression bonded internal design
- Lead-free pure tin plated terminals
- High temperature soldering capability
Applications
- Voltage regulation circuits
- Overvoltage protection
- Reference voltage generation
Procurement Notes
Verify the specific suffix 'R0G' against the manufacturer's official datasheet to confirm packaging details, as standard 'G' variants typically indicate RoHS compliance. Ensure the requested quantity matches the factory reel pack size specified in the latest documentation. Confirm that the DO-41 package dimensions align with your PCB footprint requirements before finalizing the order.
Selection Notes
Select this component when a 33V reference is required in a through-hole application. The 1W power rating allows for higher current handling compared to 500mW equivalents. Verify that the 45Ω dynamic impedance meets the noise and stability requirements of the target circuit. The wide operating temperature range supports use in industrial environments.
Part Context
This part belongs to the 1N47xx series of 1W Zener diodes produced by Taiwan Semiconductor. The series covers a wide voltage range from 3.3V to 56V. The 'G' suffix generally denotes RoHS compliance and lead-free termination. These devices are designed for general-purpose voltage regulation and protection in commercial and industrial electronics.
Replacement Considerations
Compatible substitutes include the 1N4752A (±5% tolerance) and 1N4752B (±2% tolerance). Other manufacturers offer equivalent parts such as the 1N4752G from Microchip or Vishay. Ensure the replacement maintains the DO-41 package and 1W power dissipation rating.
