1N5368C/TR12

Overview

The Microchip Technology 1N5368C/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 47 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA and a dynamic impedance of 25 Ω at a test current of 25 mA. The component utilizes a T-18 axial lead package and is supplied in tape and reel format.

Feature Summary

• Provides precise voltage regulation with tight manufacturing tolerances
• Capable of handling high surge stresses and steady-state power dissipation
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring stable reference levels
• Power supply protection against overvoltage conditions
• Clamping applications in electronic systems

Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required tolerance and packaging specifications. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Validate that the supplier provides official datasheets matching the JEDEC registered series documentation.

Selection Notes

Select this component when a 47 V reference with strict ±2% accuracy is required. Ensure the application design accounts for the 5 W power dissipation limit and appropriate heat sinking strategies. Verify that the operating current remains within the specified test parameters for optimal impedance performance.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi. The series offers a wide selection of voltages from 3.3 V to 200 V in a robust plastic encapsulated axial-lead package designed for high reliability.

Replacement Considerations

Equivalent parts include other 47 V 5 W Zener diodes from the same series such as 1N5368B or 1N5368A, provided the tolerance requirements align with the application needs.
