1N5359BRLG

Overview

The onsemi 1N5359BRLG is a single-channel voltage regulator diode featuring a nominal Zener voltage of 24 V and a maximum power dissipation of 5 W. It utilizes a DO-15 axial through-hole package with two pins. The component operates within a temperature range of -65°C to 200°C, maintaining a maximum Zener impedance of 3.5 Ω and a reverse leakage current of 500 nA at 18.2 V. Designed for robust performance, it offers a ±5% tolerance and is tested at 50 mA.

Feature Summary

• Provides stable voltage regulation across broad operating currents and temperature ranges
• Features flexible axial-lead mounting terminals for reliable through-hole installation
• Engineered with low thermal resistance design to support high DC currents with adequate heat sinking

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation in electronic devices

Procurement Notes

Verify the specific suffix 'B' confirms the required ±5% tolerance against project specifications. Ensure the DO-15 axial lead form factor matches the PCB layout constraints. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer's latest datasheet for any potential updates to mechanical dimensions or electrical characteristics prior to ordering.

Selection Notes

Select this component when a 24 V reference point is required with significant power handling capabilities. The 5 W rating allows operation at higher currents compared to lower-power variants. Verify that the system can accommodate the thermal requirements associated with the specified power dissipation. Consider the wide operating temperature range for harsh environment applications.
