Overview
The Microchip Technology 1N5353BE3/TR13 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 16V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a test current of 75mA, a maximum dynamic impedance of 2.5 Ohms, and a maximum reverse leakage current of 1µA.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for through-hole integration
- Constructed with a void-free transfer molded thermosetting epoxy body
Applications
- Voltage regulation circuits requiring 5W power dissipation
- Power supply reference designs
- Overvoltage protection applications
Procurement Notes
Verify component authenticity against official Microchip or Microsemi datasheets. Confirm the presence of the e3 suffix indicates RoHS compliance and TR13 suffix denotes tape and reel packaging. Ensure thermal management meets the specified junction-to-lead thermal resistance requirements for reliable operation.
Selection Notes
Select this component when a 16V regulated output is required with ±5% tolerance. Consider the 5W power rating and T-18 package size for adequate heat sinking. Verify that the operating environment falls within the -65°C to +150°C range and that the circuit design accommodates the specified dynamic impedance and leakage current limits.
Part Context
This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally produced by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V. The 1N5353 variant specifically targets the 16V regulation point within this high-power axial-leaded family.
Replacement Considerations
Surface mount equivalents are available as SMBJ5353B or SMBG5353B. Cross-reference with other manufacturers offering 1N5353 specifications ensuring matching power ratings, voltage tolerances, and package dimensions.
