Overview
The Microchip Technology 1N5359BE3/TR8 is a silicon Zener diode with a nominal voltage of 24 V and a ±5% tolerance. It operates in the T-18 axial lead package, dissipating up to 5 W at 25 °C. The device features a maximum dynamic impedance of 3.5 Ω and a test current of 50 mA. It withstands temperatures from -65 °C to +150 °C and includes RoHS compliance indicated by the e3 suffix.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals for through-hole applications
- Withstands high surge stresses and exhibits minimal voltage change versus current
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify the component matches the exact JEDEC registered part number 1N5359BE3/TR8. Confirm the presence of the e3 suffix for RoHS compliance and TR8 for tape and reel packaging. Ensure the supplier provides official datasheets confirming the 5 W power rating and T-18 package dimensions before finalizing procurement.
Selection Notes
Select this component when a 24 V reference with tight ±5% tolerance is required. The 5 W power dissipation capability allows operation at high DC currents with adequate heat sinking. Verify that the T-18 axial package fits the mechanical constraints of the target PCB layout.
Part Context
This part belongs to the 1N5333B through 1N5388B series of 5 Watt Zener Diodes manufactured by Microsemi (now Microchip Technology). The series covers voltages from 3.3 V to 200 V. The 1N5359 variant specifically targets the 24 V segment within this standardized JEDEC registered lineup.
Replacement Considerations
Compatible substitutes include other 24 V, 5 W Zener diodes in the T-18 package from manufacturers such as Vishay or ON Semiconductor. Ensure replacement parts match the 3.5 Ω dynamic impedance and ±5% voltage tolerance specifications.
