1N1369A

Overview

The Microchip Technology 1N1369A is a high-power Zener diode engineered for precise voltage regulation applications. It features a nominal Zener voltage of 56V and a maximum power dissipation rating of 10W. The component is housed in the DO-203AA (DO-4) axial leaded package, which facilitates robust thermal management and secure mounting via stud or chassis configurations. Designed for reliability in demanding environments, this device maintains stable performance under significant current loads, making it suitable for industrial and commercial power supply circuits requiring durable voltage reference solutions.

Feature Summary

• Provides stable voltage regulation with a fixed 56V Zener potential
• Supports high power dissipation up to 10W for robust operation
• Utilizes DO-203AA axial package for effective heat sinking and mechanical stability

Applications

• High-power voltage reference circuits
• Industrial power supply regulation
• Overvoltage protection systems

Procurement Notes

Verify the specific manufacturer source, as the 1N1369A designation has been produced by multiple entities including Harris and Actel. Confirm that the received component matches the required electrical specifications and physical package dimensions. Ensure documentation aligns with Microchip Technology standards if that specific origin is mandated for the design. Check for any suffix variations that might indicate different tolerance grades or testing levels.

Selection Notes

Select this component when a 56V regulation point is required with substantial power handling capabilities. The 10W rating necessitates adequate thermal design, such as heatsinking or stud mounting, to maintain junction temperatures within safe limits. Compare against lower-power alternatives if space constraints are critical, but prioritize this part for applications where long-term stability and high current capacity are essential requirements.

Part Context

The 1N1369A belongs to the 1N13 series of Zener diodes, which are characterized by their ability to provide precise voltage regulation in compact yet rugged packages. This series is widely recognized for its reliability in military and industrial sectors. The 1N1369A specifically addresses the need for higher power dissipation compared to standard signal diodes, bridging the gap between low-power references and heavy-duty voltage clamping devices.

Replacement Considerations

Direct substitutes may include other 1N13 series variants with similar voltage and power ratings, provided the package compatibility is verified. Cross-reference with equivalent parts from other manufacturers ensuring the 56V Zener voltage and 10W power dissipation match exactly. Verify pinout and thermal characteristics before substitution.
