Overview
The 1N4740G R0G is a silicon Zener diode manufactured by Taiwan Semiconductor Corporation. It provides a nominal Zener voltage of 10 V with a tolerance of 5%. The device is rated for a maximum power dissipation of 1 W at ambient temperature. It utilizes an axial-leaded DO-41 package, suitable for through-hole mounting. The component operates within a junction temperature range of -65 °C to +175 °C and features a matte tin terminal finish compliant with RoHS standards.
Feature Summary
- Provides stable voltage regulation via the Zener breakdown effect in reverse bias conditions.
- Utilizes a rugged glass passivation technique for enhanced environmental stability.
- Features a standard axial-leaded package designed for automated insertion processes.
Applications
- Voltage reference circuits requiring precise potential levels.
- Overvoltage protection stages in power supply inputs.
- Clamping applications to limit signal amplitude peaks.
Procurement Notes
Verify the specific suffix 'R0G' against official Taiwan Semiconductor documentation to confirm reel packaging specifications and tape dimensions. Ensure the requested quantity aligns with manufacturer minimum order requirements. Confirm RoHS compliance status directly with the supplier prior to finalizing procurement orders.
Selection Notes
Select this component when a 10 V regulation point is required with 1 W power handling capability. The DO-41 package offers mechanical robustness for general-purpose board layouts. Consider thermal derating factors if operating in enclosed environments or at elevated ambient temperatures above standard ratings.
Part Context
This part belongs to the standard 1N47xx series of Zener diodes, widely utilized for basic voltage regulation tasks. The 'G' suffix typically denotes Green/RoHS compliance, while 'R0G' specifies the specific reel packaging configuration used by Taiwan Semiconductor for automated assembly lines.
Replacement Considerations
Cross-reference with other manufacturers offering the 1N4740 specification. Verify that substitute parts maintain identical 10 V Zener voltage, 1 W power rating, and DO-41 package dimensions to ensure direct compatibility without circuit modification.
