1N4750AHR1G

Overview

The 1N4750AHR1G is a single silicon Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 27 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 parameters include a maximum reverse leakage current of 5 uA, a Zener impedance of 35 Ohms, and a test current of 9.5 mA. It is housed in the DO-41-2 (DO-204AL) through-hole package.

Feature Summary

• Provides stable voltage regulation at a nominal 27 V level
• Capable of handling 1 W power dissipation in a standard axial leaded package
• Qualified for automotive applications under AEC-Q101 standards

Applications

• Automotive electronic circuits requiring robust voltage reference
• General-purpose voltage regulation in industrial equipment
• Protection against overvoltage transients in DC power lines

Procurement Notes

Verify the specific suffix HR1G to confirm AEC-Q101 automotive qualification status. Confirm the package type is DO-41-2 as specified. Check RoHS compliance details via official datasheets. Ensure the manufacturer is Taiwan Semiconductor Corporation. Validate availability directly with the factory or authorized distributors.

Selection Notes

Select this component when automotive-grade reliability is required for 27 V regulation. The 1 W rating supports higher current loads compared to lower-power variants. The DO-41-2 package facilitates easy through-hole mounting. Verify that the 5% voltage tolerance meets circuit precision requirements. Consider the operating temperature range up to 150 °C for high-heat environments.

Part Context
