1N5369B-AP

Overview

The MCC 1N5369B-AP is a silicon unidirectional Zener diode with a nominal voltage of 51V and a tolerance of ±5%. It features a maximum power dissipation of 5W and operates within a temperature range of -55°C to +150°C. The device utilizes an axial DO-15 plastic package and exhibits a maximum dynamic impedance of 27 Ohms. It is designed for general-purpose voltage regulation applications requiring robust thermal performance.

Feature Summary

• Provides stable voltage regulation at 51V with high power handling capability
• Constructed with silicon material in a durable plastic encapsulated axial package
• Capable of operation across a wide industrial temperature spectrum

Applications

• General purpose voltage regulation circuits
• Power supply protection stages
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific suffix AP against manufacturer documentation to confirm packaging details, as standard variants may differ. Ensure compatibility with existing circuit thermal management requirements given the 5W dissipation rating. Cross-reference datasheets from authorized distributors to confirm current production status and RoHS compliance specifications before finalizing procurement plans.

Selection Notes

Select this component when a 51V Zener reference with 5W power capacity is required in an axial form factor. Consider the 27 Ohm dynamic impedance for regulation precision needs. Evaluate the DO-15 package dimensions for board space constraints. Compare against other manufacturers' equivalents if supply chain diversification is necessary.

Part Context

This part belongs to the 1N5369 series of high-power Zener diodes manufactured by Micro Commercial Components. The series typically covers a range of voltages from 5.1V to 200V, offering reliable performance for industrial and commercial electronics. The 1N5369 variant specifically targets the 51V regulation niche within this broader product family.

Replacement Considerations

Direct substitutes include the 1N5369B from onsemi and PANJIT, which share identical electrical ratings and DO-15 packaging. Verify pinout orientation and thermal resistance characteristics when swapping between different manufacturers to ensure equivalent circuit performance.
