1N4735A_NT50A

Overview

The onsemi 1N4735A is a silicon planar power Zener diode housed in a DO-41 glass case. It provides a nominal voltage of 6.2 V with a 5% tolerance at a test current of 41 mA. The device dissipates up to 1.0 W at lead temperatures below 50°C, derating by 6.67 mW/°C above that threshold. Key electrical characteristics include a maximum dynamic impedance of 2 Ω and a leakage current of 10 µA at 1 V reverse bias. It supports an operating and storage temperature range from -65°C to +200°C.

Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a glass DO-41 axial package for through-hole mounting
• Provides stable reference voltages with tight manufacturing tolerances

Applications

• Voltage reference circuits
• Overvoltage protection
• Power supply regulation

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and marking variations. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure thermal management aligns with the specified derating curve for continuous operation above 50°C lead temperature.

Selection Notes

Select this component when a standard 6.2 V reference is required in a high-power dissipation environment. The DO-41 package accommodates higher thermal loads compared to smaller surface-mount alternatives. Verify that the 41 mA test current requirement fits within the available drive capability of the host circuit design.

Part Context

This part belongs to the 1N4728A–1N4758A series of general-purpose Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 56 V, all sharing similar physical dimensions and thermal characteristics within the DO-41 glass case format.

Replacement Considerations

Cross-reference with other manufacturers' 1N4735A equivalents such as those from Nexperia or Vishay. Verify that substitute parts meet the identical 6.2 V nominal voltage, 5% tolerance, and 1 W power dissipation ratings.
