1N5368B

Overview

The onsemi 1N5368B is a silicon voltage regulator diode from the 1N53 Series, featuring a nominal Zener voltage of 47 V with a ±5% tolerance. It operates in an axial lead Surmetic 40 (DO-15) package and supports a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C. The device exhibits a reverse leakage current of up to 0.8 µA at 35.8 V and a maximum Zener impedance of 25 Ω at a test current of 25 mA. It withstands a peak forward surge current of 30 A for an 8.3 ms pulse width.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for improved operating characteristics and reliability.
• Features a void-free, transfer-molded thermosetting plastic case that provides corrosion resistance and environmental protection.
• Includes built-in strain relief within the axial lead design to enhance mechanical durability during mounting.

Applications

• Voltage regulation in electronic circuits requiring stable reference levels.
• Protection against transient overvoltage events in power supply systems.
• Clamping applications in signal processing and communication equipment.

Procurement Notes

Verify the specific ordering suffix when purchasing; the 'G' suffix indicates a Pb-Free package. Confirm compliance with RoHS directives if required by your manufacturing standards. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee component authenticity and traceability.

Selection Notes

Select this component for designs requiring a precise 47 V regulation point with high surge capability. Consider the thermal resistance characteristics and derating requirements above 25°C ambient temperature. Verify that the application environment does not exceed the specified maximum junction temperature limits for continuous operation.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, utilizing robust axial lead packages designed for general-purpose industrial and commercial electronics applications.

Replacement Considerations

Compatible substitutes include the 1N5368B-TP from Micro Commercial Components and the 1N5368B from Transys Electronics Limited. These alternatives share identical electrical ratings and DO-15 packaging specifications.
