1N4757A_T50A

Overview

The onsemi 1N4757A_T50A is a silicon planar Zener diode housed in a DO-41 glass axial leaded package. It provides a nominal Zener voltage of 51 V with a ±5% tolerance, tested at a current of 5 mA. The device supports a maximum power dissipation of 1 W and features a low leakage current of 5 µA at 38.8 V reverse bias. Its dynamic impedance is specified at 95 Ω, and it operates reliably within a temperature range from -65 °C to +200 °C.

Feature Summary

• Provides stable voltage regulation for clipping and stabilizing circuits
• Features a robust DO-41 glass case designed for high thermal stability
• Ensures precise voltage control through tight manufacturing tolerances

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• Waveform clipping and shaping applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets all required environmental standards and regulatory compliance specifications before final integration into the design.

Selection Notes

Select this component when a 51 V regulation point is required with strict tolerance limits. Ensure the application environment stays within the specified operating temperature range and that the power dissipation requirements do not exceed the rated maximum without proper heat sinking.

Part Context

This part belongs to the 1N47xx series of power Zener diodes manufactured by onsemi. The series utilizes silicon planar technology to deliver consistent performance across various industrial and commercial applications. The 'A' suffix indicates a tighter voltage tolerance compared to standard variants.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4757A designation. Verify that any substitute maintains identical pinout, voltage rating, and package dimensions to ensure mechanical compatibility.
