Overview
The Microchip Technology 1N5350E3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 13 volts with a standard tolerance of plus or minus 5 percent, indicated by the B 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, while the TR12 suffix indicates tape and reel packaging.
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 versatile installation
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack
Applications
- Voltage regulation circuits
- Reference voltage sources
- Overvoltage protection systems
Procurement Notes
Verify that the component matches the specific part number 1N5350E3/TR12 to ensure correct voltage rating and tolerance. Confirm the presence of the e3 suffix for RoHS compliance and the TR suffix for tape and reel packaging. Check datasheets for thermal derating requirements when calculating maximum power dissipation under actual operating conditions.
Selection Notes
Select this component for applications requiring a 13-volt reference with 5-watt power handling capabilities. Ensure the circuit design accommodates the specified dynamic impedance and reverse leakage current parameters. Verify that the ambient temperature and heat sinking methods align with the junction-to-ambient thermal resistance specifications provided in the datasheet.
Part Context
This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage selection from 3.3 to 200 volts with various tolerance options. These plastic encapsulated diodes are designed for high DC currents with adequate heat sinking due to their low thermal resistance design.
Replacement Considerations
Direct replacements include other 1N5350 variants such as 1N5350A or 1N5350C depending on required tolerance. Surface mount equivalents like SMBJ5350BE3 offer similar electrical characteristics in a different package form factor.
