Overview
The Microchip Technology 1N5359AE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 24 volts with a ±10% tolerance. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum reverse current of 0.5 µA and a dynamic impedance of 3.5 ohms.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Flexible axial-lead mounting terminals for through-hole applications
- Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020
- Withstands high surge stresses during operation
Applications
- Voltage regulation in power supply circuits
- Protection against overvoltage conditions
- Reference voltage generation in electronic systems
Procurement Notes
Verify component authenticity and datasheet alignment before integration. Confirm that the e3 suffix indicates RoHS compliance and the TR8 suffix specifies tape and reel packaging. Ensure the specific part number matches the required voltage tolerance and thermal ratings for your design requirements.
Selection Notes
Select this component when a 5-watt power rating and 24-volt regulation are required. The ±10% tolerance suits general-purpose applications. Consider the T-18 package dimensions and lead length for PCB layout. Verify thermal management needs as power dissipation depends on mounting methods.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. Originally produced by Microsemi's Scottsdale Division, these devices are now under Microchip Technology. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters.
Replacement Considerations
Compatible substitutes include other 5W Zener diodes with 24V nominal voltage and similar axial packages. Verify electrical parameters such as dynamic impedance and reverse current match the original specifications.
