Overview
The Microchip Technology 1N5359CE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi. It provides voltage regulation at a nominal Zener voltage of 24 V with a tight tolerance of ±2%. The device operates in an ambient temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum reverse current of 0.5 µA and a dynamic impedance of 3.5 Ω.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and offers minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for secure installation
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack
Applications
- Voltage regulation in power supply circuits
- Reference voltage generation in electronic systems
- Overvoltage protection applications
Procurement Notes
Verify component authenticity through authorized channels as this part originates from the Microsemi Scottsdale Division. Confirm RoHS compliance status via the e3 suffix designation. Ensure proper handling procedures are followed during storage and assembly to maintain the specified moisture classification level.
Selection Notes
Select this component when a precise 24 V reference with ±2% tolerance is required. The 5 W power dissipation rating supports high-current operation with adequate heat sinking. Verify that the T-18 axial package fits the mechanical constraints of the target PCB layout.
Part Context
This device belongs to the 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'C' suffix indicates a tighter ±2% voltage tolerance compared to standard B (±5%) or A (±10%) variants. The 'e3' suffix denotes RoHS compliance with matte tin plating on the leads.
Replacement Considerations
Compatible substitutes within the same series include 1N5359B and 1N5359A, provided their respective voltage tolerances align with design requirements.
