1N4757G R0G

Overview

The 1N4757G R0G is a silicon planar power Zener diode manufactured by Taiwan Semiconductor Corporation. It features a DO-204AL (DO-41) glass axial-leaded package and provides a nominal Zener voltage of 51 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W at an ambient temperature of 25°C. It operates within a junction temperature range of -65°C to +200°C and includes solderable terminals compliant with MIL-STD-202, method 208.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Features a hermetically sealed glass DO-41 encapsulation
• Provides high power dissipation capability for stabilizing circuits

Applications

• Voltage stabilization in high-power electronic circuits
• Waveform clipping applications requiring robust power handling
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compliance with required tolerance levels and environmental standards. Confirm terminal plating specifications and RoHS status prior to integration into designs requiring strict material restrictions.

Selection Notes

Select this component when a 51 V reference with ±5% accuracy is required in a through-hole glass package. Ensure the application allows for adequate thermal management to support the 1 W dissipation rating without exceeding the maximum junction temperature limits defined in the electrical characteristics.

Part Context

This part belongs to the standard 1N47xx series of 1-watt Zener diodes widely used in discrete semiconductor applications. The base 1N4757 designation typically indicates a 10% tolerance, while the 'A' or specific suffix variants denote tighter tolerances such as ±5%. The G R0G suffix identifies the specific packaging and compliance attributes provided by Taiwan Semiconductor.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4757A specification in DO-41 packages. Verify that substitute parts match the 51 V nominal voltage, ±5% tolerance, and 1 W power rating to maintain circuit performance integrity.
