Overview
The 1N4740A B0G is a glass-passivated junction silicon Zener diode manufactured by Taiwan Semiconductor. It provides a nominal Zener voltage of 10 V with a tolerance of 5%. The device is rated for a 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 10 uA, a Zener impedance of 7 Ohms, and a test current of 25 mA. It utilizes the DO-41-2 axial through-hole package.
Feature Summary
- Glass passivated chip junction for enhanced environmental stability
- Built-in strain relief in the lead frame design
- Low inductance construction suitable for general switching applications
Applications
- Voltage regulation circuits
- Reference voltage sources
- Overvoltage protection
Procurement Notes
Verify the specific suffix 'B0G' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the component meets RoHS Directive 2011/65/EU requirements if applicable to your assembly process. Cross-reference the Mouser part number 821-1N4740AA0G or similar identifiers for accurate sourcing from authorized distributors.
Selection Notes
Select this component when a standard 10 V reference is required in a through-hole configuration. The 1 W power rating supports moderate current loads compared to lower-power variants. Verify that the operating environment stays within the specified -55 °C to +150 °C range to maintain performance integrity.
Part Context
This part belongs to the 1N4740A series of 1 Watt Zener diodes produced by Taiwan Semiconductor. The series covers a wide range of voltage values, all sharing the same DO-41 axial package and glass-passivated construction. This specific variant targets the 10 V segment of the lineup.
Replacement Considerations
Compatible substitutes include the Vishay 1N4740A and Microchip 1N4740AE3. These alternatives share identical electrical specifications and mechanical dimensions, allowing for direct pin-to-pin replacement in existing designs.
