1N5353B-AP

Overview

The MCC 1N5353B-AP is a Zener diode manufactured by Micro Commercial Components. It belongs to the 1N53xxB series of axial-leaded, plastic encapsulated devices rated for 5.0 watts of power dissipation. The component provides voltage regulation with a standard tolerance of ±5%, indicated by the 'B' suffix. It features a DO-15 (DO-204AC) through-hole package and is designed for operation within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses due to low thermal resistance design
• Plastic encapsulation offers protection in common environmental conditions

Applications

• Voltage regulation in industrial process control systems
• Power supply circuit protection and reference voltage generation
• General-purpose electronic equipment requiring robust axial-lead components

Procurement Notes

Verify the specific manufacturer part number against official datasheets to confirm compliance with JEDEC registration standards. Ensure that the required voltage tolerance and power dissipation ratings align with the design specifications. Confirm availability status as distribution channels may vary by region. Check for RoHS compliance if required by project constraints.

Selection Notes

Select this component when a 5-watt axial Zener diode with ±5% tolerance is required. Consider the DO-15 package dimensions for PCB layout compatibility. Evaluate thermal management requirements for high-current applications to ensure reliable operation within the specified temperature limits.

Part Context

This device is part of the broader 1N5333B to 1N5388B series registered with JEDEC. The series includes various voltage options ranging from 3.3V to 200V. Other variants in the family include different tolerance levels (A, C, D suffixes) and surface mount equivalents such as SMBJ or SMBG series packages.

Replacement Considerations

Compatible replacements include other manufacturers' 1N5353B axial Zener diodes. Surface mount alternatives like the SMBJ5353B series are available for space-constrained designs. Verify pinout and electrical parameters match before substitution.
