1N4755A_T50R

Overview

The onsemi 1N4755A_T50R is a silicon planar Zener diode housed in a DO-41 glass case. It provides a nominal Zener voltage of 43V with a ±5% tolerance, tested at a current of 5.9 mA. The device supports a maximum power dissipation of 1.0 W at lead temperatures up to 50°C and operates within a junction temperature range of -65°C to +200°C. Key electrical characteristics include a maximum dynamic impedance of 6 ohms at the test current and a leakage current not exceeding 25 µA at a reverse voltage of 32.7 V.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Features a glass passivated die for environmental protection
• Provides precise voltage clamping with tight tolerance specifications

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Clipping and wave shaping applications

Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. Confirm compliance with RoHS directives and specific marking requirements before finalizing procurement. Ensure the component meets the intended thermal and electrical operating conditions for the target application.

Selection Notes

Select this component when a 43V regulation point is required with moderate precision. Consider the DO-41 package constraints for through-hole mounting. Evaluate thermal derating requirements if ambient temperatures exceed standard limits.

Part Context

This part belongs to the 1N4728A through 1N4758A series of one-watt Zener diodes manufactured by onsemi. The series covers a wide range of voltage ratings from 3.3V to 200V, utilizing a standardized DO-41 axial leaded package for consistent mechanical integration across various electronic designs.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4755A equivalents in the DO-41 package. Verify that substitute parts meet the same 43V nominal voltage, 1W power rating, and ±5% tolerance specifications.
