Overview
The Taiwan Semiconductor 1N4751A R1G is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 30 V with a tolerance of 5%. The device supports a maximum power dissipation of 1 W and operates within a temperature range from -65 °C to +200 °C. Packaged in the DO-41-2 through-hole format, it exhibits a maximum reverse leakage current of 5 uA and a Zener impedance of 40 Ohms at a test current of 8.5 mA.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Utilizes glass passivation for enhanced environmental protection and reliability
- Designed for high thermal stability with an extended maximum junction temperature rating
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- General-purpose voltage regulation in power supplies
Procurement Notes
Verify the specific suffix 'R1G' against official manufacturer documentation to confirm packaging details and compliance status. Ensure that the ordering information matches the required RoHS and REACH specifications. Cross-reference the part number with authorized distributors to validate authenticity and availability before procurement.
Selection Notes
Select this component when a 30 V regulation point is required in a through-hole configuration. Consider the 1 W power rating and 5% voltage tolerance for circuit design margins. Evaluate the thermal performance requirements against the specified operating temperature range to ensure reliable operation under load conditions.
Part Context
This component belongs to the standard 1N47xxA series of Zener diodes manufactured by Taiwan Semiconductor. The series offers a wide selection of voltage values within the same package footprint, facilitating design flexibility. The 1N4751A variant specifically targets applications needing a 30 V breakdown voltage with standard industrial tolerances.
Replacement Considerations
Compatible substitutes include the onsemi 1N4751A and Micro Commercial Components 1N4751A-AP. Verify pinout compatibility and electrical parameter alignment, particularly Zener voltage and power dissipation ratings, before implementing any alternative components.
