Overview
The 1N4755A B0G is a through-hole Zener diode manufactured by Taiwan Semiconductor, designed for voltage regulation applications. It features a nominal Zener voltage of 43 V with a tolerance of 5%. The component operates in the DO-41 (DO-204AL) axial leaded package and supports a maximum power dissipation of 1 W. Key electrical characteristics include a maximum reverse leakage current of 5 uA and a Zener impedance of 70 Ohms at a test current of 6 mA. The device is rated for a junction temperature up to 200 °C and an operating range from -65 °C to +200 °C.
Feature Summary
- Provides stable voltage regulation via Zener breakdown mechanism
- Utilizes hermetically sealed glass compression bonded construction
- Supports high thermal stability with elevated junction temperature ratings
Applications
- Voltage reference circuits
- Overvoltage protection systems
- Clipper and clamper circuits
Procurement Notes
Verify the specific suffix 'B0G' against the manufacturer's official datasheet to confirm packaging details and compliance status. Ensure the ordering part number matches the exact specifications required for your design, as suffixes often denote tape-and-reel quantities or specific environmental certifications distinct from standard bulk packaging.
Selection Notes
Select this component when a 43 V regulation point is required in a through-hole assembly process. The DO-41 package offers robust mechanical mounting compared to surface mount alternatives. Consider the 70 Ohm impedance value for dynamic load regulation requirements and ensure the circuit can handle the 1 W power dissipation without exceeding thermal limits.
Part Context
This component belongs to the 1N47xxA series of silicon Zener diodes. The series provides a wide range of voltage options within the same standardized DO-41 package form factor. These devices are widely used in general-purpose electronics for their reliability and consistent performance across industrial and commercial temperature ranges.
Replacement Considerations
Cross-reference with other manufacturers offering the 1N4755A specification in the DO-41 package. Verify that substitute parts match the 43 V nominal voltage, 5% tolerance, and 1 W power rating. Check for equivalent Zener impedance and leakage current specifications to ensure circuit compatibility.
