Overview
The Microchip Technology 1N5368AE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation with a nominal Zener voltage of 47 volts and a tolerance of plus or minus 10 percent, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. RoHS compliance is confirmed by the 'e3' suffix, and tape and reel packaging is specified by the 'TR8' suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for secure installation
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection systems
- Reference voltage generation in electronic designs
Procurement Notes
Verify the component manufacturer as Microsemi (now part of Microchip Technology) to ensure authenticity. Confirm that the specific ordering suffixes match the required electrical tolerances and packaging format. Check for any product change notifications regarding manufacturing origin or material composition updates before finalizing procurement decisions.
Selection Notes
Select this component when a 47-volt regulation point with 10 percent tolerance is required. Ensure the application can accommodate the 5-watt power dissipation rating and provide adequate heat sinking if necessary. Verify that the axial lead form factor fits the available board space and mounting constraints.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages ranging from 3.3 volts to 200 volts. Different suffix letters identify specific voltage tolerances, while the e3 suffix denotes RoHS compliance. The TR8 suffix indicates tape and reel packaging for automated assembly.
Replacement Considerations
Compatible substitutes include other 1N5368 variants with matching voltage and tolerance specifications. Surface mount equivalents such as SMBJ5368 are available for applications requiring different form factors. Verify thermal resistance and package dimensions when substituting.
