1N5311 TR TIN/LEAD

Overview

The Central Semiconductor 1N5311 TR TIN/LEAD is a silicon planar power Zener diode designed for voltage regulation and reference applications. It features a maximum DC power dissipation of 50 watts at an ambient temperature of 25°C, reducing to 25 watts at 100°C. The device operates within a junction temperature range of -65°C to +200°C and maintains a storage temperature range of -65°C to +200°C. Key electrical specifications include a nominal Zener voltage of 47 volts with a tolerance of ±5%, a maximum reverse leakage current of 5 microamperes at the rated voltage, and a Zener impedance of 1.8 ohms measured at a test current of 53 milliamperes.

Feature Summary

High power handling capability suitable for robust voltage regulation tasks
Wide operating temperature range supporting extreme environmental conditions
Low leakage current characteristics ensuring stable reference performance

Applications

Industrial power supply voltage regulation
Overvoltage protection circuits
Voltage reference standards in measurement equipment

Procurement Notes

Verify the specific ordering suffix required for the desired plating finish when placing orders. Confirm that the manufacturer accepts the requested tin/lead configuration as availability may vary by production batch. Ensure all technical parameters align with the official datasheet before finalizing procurement documentation.

Selection Notes

Select this component based on its 50-watt power rating and 47-volt Zener voltage requirement. Verify that the package style matches the thermal management strategy of the target design. Consider the maximum reverse leakage current and impedance values to ensure compatibility with precision requirements.

Part Context

This part belongs to the standard 1N53xx series of high-power Zener diodes manufactured by Central Semiconductor. These devices are widely used in industrial and commercial electronics where reliable voltage clamping and regulation are necessary under high power conditions.

Replacement Considerations

Cross-reference with other manufacturers offering equivalent 50W, 47V Zener diodes in compatible packages such as DO-201 or DO-15. Verify pinout compatibility and thermal resistance specifications to ensure seamless integration without redesigning the PCB layout.
