Overview
The Taiwan Semiconductor 1N4732G is a single silicon Zener diode housed in a DO-41 axial through-hole package. It provides a nominal Zener voltage of 4.7 V with a standard tolerance of ±5%. The device supports a maximum power dissipation of 1 W and operates within a junction temperature range of -65°C to +200°C. Electrical characteristics include a test current of 53 mA, a maximum Zener impedance of 8 Ω at the test current, and a leakage current of 10 µA at 1 V reverse voltage.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Wide selection of Zener voltages ranging from 3.3V to 56V
- Standardized ±5% tolerance on nominal Zener voltage
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converter
Procurement Notes
Verify the specific part number against official datasheets to confirm electrical parameters such as Zener voltage and impedance. Ensure the procurement matches the required package type and compliance standards. Confirm availability directly with authorized distributors or the manufacturer, as supply chain conditions may vary.
Selection Notes
Select this component based on the required 4.7 V reference voltage and 1 W power handling capability. Consider the DO-41 through-hole package for mechanical mounting requirements. Evaluate thermal resistance values if operating near maximum junction temperatures. Verify that the ±5% tolerance meets the circuit's precision requirements.
Part Context
This component belongs to the 1N4728G–1N4758G series manufactured by Taiwan Semiconductor. The series covers a broad range of Zener voltages from 3.3V to 56V, all sharing similar physical dimensions and hermetically sealed glass packaging. The 1N4732G specifically addresses the 4.7V segment of this standardized lineup.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4732 equivalents in the DO-41 package. Verify matching specifications for Zener voltage, power dissipation, and impedance. Ensure any substitute maintains the same hermetic sealing and temperature ratings.
