1N4735A-T50A

Overview

The Fairchild Semiconductor 1N4735A-T50A is a single silicon Zener diode housed in an axial leaded DO-41 package. It provides a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum dynamic impedance of 2 Ω at the test current, a leakage current of 10 µA, and a non-repetitive peak reverse current rating of 700 mA.

Feature Summary

• Provides stable voltage regulation through controlled Zener breakdown characteristics
• Features low dynamic impedance for effective noise suppression and signal conditioning
• Constructed with a robust glass or plastic encapsulated axial lead design for reliable through-hole mounting

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clipping and clamping applications in waveform processing

Procurement Notes

Verify that the ordering suffix T50A corresponds to the Fan-Fold shipping configuration as specified in the official documentation. Confirm compliance with RoHS and halide-free standards during acquisition. Ensure the component matches the specific manufacturer designation to guarantee accurate electrical performance and physical dimensions.

Selection Notes

Select this component when a 6.2 V regulated output is required in a standard axial package. Consider the 1 W power dissipation capability and the wide operating temperature range for demanding environments. Evaluate the low dynamic impedance specification against circuit requirements for optimal noise filtering and stability.

Part Context

This part belongs to the 1N4728A through 1N4758A series of Zener diodes manufactured by onsemi (formerly Fairchild Semiconductor). The series utilizes the standardized JEDEC DO-41 case outline, ensuring mechanical compatibility across various manufacturers. These components are widely utilized in general-purpose electronics for fundamental voltage regulation tasks.

Replacement Considerations

Cross-reference with other 1N4735A variants from different manufacturers to ensure identical pinout and electrical specifications. Verify that alternative packages maintain the same thermal derating characteristics and lead length requirements for proper heat dissipation.
