Overview
The Microchip Technology 1N5353A/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 16 V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum reverse current of 1.0 µA and a maximum dynamic impedance of 2.5 Ω.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and offers flexible axial-lead mounting terminals
- Features minimal changes in voltage versus current as specified by voltage regulation parameters
Applications
- Voltage regulation circuits requiring robust thermal performance
- Power supply protection against high surge stresses
- General purpose voltage reference applications
Procurement Notes
Verify that the component matches the specific suffix requirements for your design. Confirm the RoHS compliance status indicated by the e3 suffix and ensure the TR12 tape and reel packaging aligns with your assembly equipment specifications before finalizing procurement.
Selection Notes
Select this component when a 16 V regulation point with ±10% tolerance is required. Ensure adequate heat sinking is provided to maintain power dissipation within the 5.0-watt limit. Verify that the T-18 through-hole package fits the PCB layout constraints.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3 V to 200 V. The 'A' suffix specifically denotes a standard ±10% voltage tolerance, distinguishing it from tighter tolerance variants like the B or C suffixes.
Replacement Considerations
Compatible substitutes include other 1N5353 variants such as 1N5353B (±5% tolerance) or 1N5353C (±2% tolerance). Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B series.
