Overview
The 1N4761AH is a single silicon Zener diode manufactured by Taiwan Semiconductor, designed for voltage regulation and clipping applications. It features a nominal Zener voltage of 75 V with a tolerance of 5%. The device operates in the DO-204AL (DO-41) through-hole package and dissipates up to 1 W of power. Key electrical characteristics include a maximum reverse leakage current of 5 uA and a Zener impedance of 175 Ohms at a test current of 3.3 mA. It supports an operating temperature range from -55 C to +150 C and holds AEC-Q101 qualification.
Feature Summary
- Provides stable voltage regulation within a broad operating current and temperature range
- Features built-in strain relief for mechanical durability
- Ensures high temperature soldering capability for robust assembly processes
Applications
- Voltage stabilization circuits
- Signal clipping applications
- Overvoltage protection systems
Procurement Notes
Verify component authenticity and availability directly with the manufacturer or authorized distributors. Confirm RoHS compliance status and specific packaging options such as reel quantities. Ensure that the AEC-Q101 automotive qualification aligns with target application requirements before finalizing procurement decisions.
Selection Notes
Select this component when a 75 V regulation point is required in axial leaded packages. Consider the 175 Ohm impedance for low-current precision needs. Verify thermal management capabilities given the 1 W dissipation limit and extended temperature range suitability for demanding environments.
Part Context
This part belongs to the 1N47xxA series of 1 W Zener diodes produced by Taiwan Semiconductor. The series offers extensive voltage selection ranging from 3.3 V to 100 V. These devices are standard industry replacements for legacy parts, providing reliable performance in general-purpose electronic circuits requiring precise voltage reference or protection.
Replacement Considerations
Cross-reference with other manufacturers' 1N4761A variants ensuring identical 75 V rating and DO-41 package compatibility. Verify equivalent Zener impedance and leakage current specifications to maintain circuit performance integrity during substitution.
