Overview
The Microchip Technology 1N5354CE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at 17 volts with a tight tolerance of plus or minus 2%. The device features an axial lead DO-41 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms, a maximum reverse current of 0.5 microamperes, and a maximum regulator current of 5.8 amperes.
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 standard through-hole integration
Applications
- Voltage regulation in power supply circuits
- Protection against overvoltage conditions
- Reference voltage generation in electronic systems
Procurement Notes
Verify that the component matches the specific 17-volt rating and 2% tolerance indicated by the 'C' suffix. Confirm the 'e3' designation ensures RoHS compliance and the 'TR13' suffix indicates tape and reel packaging. Ensure the supplier source aligns with authorized distribution channels for this Microchip Technology part number.
Selection Notes
Select this component when a 5-watt power dissipation capability is required for higher current applications compared to lower wattage Zener diodes. The 17-volt breakdown voltage suits specific reference needs, while the 2% tolerance provides tighter accuracy than standard 5% variants. Verify thermal management requirements due to the significant power handling capacity.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3 to 200 volts. The 1N5354 variant specifically targets the 17-volt regulation point within this extensive lineup.
Replacement Considerations
Compatible substitutes include other 1N5354 variants with different tolerances such as 1N5354B (±5%) or 1N5354D (±1%). Surface mount equivalents like SMBJ5354 are available for space-constrained designs.
