1N4740AHB0G

Overview

The 1N4740AHB0G is a single Zener diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and utilizes a DO-204AL (DO-41) through-hole package. It is RoHS3 compliant and AEC-Q101 qualified, indicating suitability for automotive applications.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Through-hole DO-204AL package construction
• RoHS3 compliant manufacturing process

Applications

• Voltage regulation in automotive electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in power supplies

Procurement Notes

Verify the specific suffix B0G against your bill of materials to ensure correct packaging and compliance status. Confirm AEC-Q101 qualification requirements if deploying in automotive environments. Check current lifecycle status directly with Taiwan Semiconductor Corporation as availability may vary. Ensure lead-free specifications meet local regulatory standards for your assembly process.

Selection Notes

Select this component when a 10 V Zener reference is required in a through-hole design. The DO-204AL package supports higher power handling compared to surface-mount alternatives. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability. Verify that the 1 W power rating aligns with the expected thermal conditions of the target circuit.

Part Context

This part belongs to the 1N4740 series of Zener diodes from Taiwan Semiconductor. The AH prefix typically denotes specific manufacturing attributes or quality grades within the company's portfolio. The B0G suffix indicates the specific tape-and-reel or bulk packaging configuration and RoHS compliance level defined by the manufacturer.

Replacement Considerations

Compatible substitutes include 1N4740AHA0G and 1N4740AHR0 from the same manufacturer. These variants share identical electrical characteristics but may differ in packaging format or reel specifications. Verify pinout compatibility and thermal performance before substitution.
