1N5378B-AP

Overview

The MCC 1N5378B-AP is a glass passivated junction silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of ±5%. The component is rated for a maximum power dissipation of 5 W and operates within a temperature range of -55°C to +150°C. It utilizes an axial leaded DO-204AC (DO-15) package, suitable for through-hole mounting.

Feature Summary

• Glass passivated junction construction for enhanced stability
• High surge current capability for transient protection
• Axial leaded package optimized for board space

Applications

• Voltage regulation in power supply circuits
• Transient voltage suppression
• Reference voltage generation

Procurement Notes

Verify the specific suffix AP against official Micro Commercial Components documentation to confirm packaging configuration and compliance status. Ensure the ordering information matches the required DO-15 axial lead format and 5W power rating specifications before finalizing procurement.

Selection Notes

Select this component when a 100 V Zener voltage with 5% tolerance is required in a high-power 5 W axial package. Confirm that the operating environment stays within the specified -55°C to +150°C junction temperature range and that the circuit design accommodates the device's surge ratings.

Part Context

This part belongs to the standard 1N53xx series of 5 Watt Zener diodes manufactured by Micro Commercial Components. The series provides a wide range of voltage options in a robust axial plastic package, commonly used in industrial and consumer electronics for reliable voltage clamping and regulation tasks.

Replacement Considerations

Compatible equivalents include the 1N5378B from other manufacturers such as ON Semiconductor or Pan Jit, provided they meet the same 100 V, 5 W, and DO-15 package requirements.
