1N1361A

Overview

The 1N1361A is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 10 W and utilizes a stud mount configuration within the DO-203AA (DO-4) package. This component is suitable for high-power circuit protection and reference voltage generation in industrial environments.

Feature Summary

• Provides stable voltage regulation at a fixed 27 V nominal level
• Capable of handling high power dissipation up to 10 W
• Utilizes a robust stud mount design for efficient thermal management

Applications

• High-power voltage regulation circuits
• Industrial equipment overvoltage protection
• Precision voltage reference sources

Procurement Notes

Verify the manufacturer marking matches Microchip Technology specifications. Confirm the package type is DO-203AA (DO-4) and the voltage rating is exactly 27 V ±5%. Ensure the component is new original stock and check for any physical damage to the stud mounting surface before integration into high-power systems.

Selection Notes

Select this component when a 27 V regulated output is required with significant power handling capabilities. The stud mount package is essential for applications demanding direct heat sinking to chassis or large heatsinks. Consider the ±5% tolerance if tighter voltage precision is needed, as other variants may offer different tolerances.

Part Context

This part belongs to the family of single Zener diodes offered by Microchip Technology. It shares the same DO-203AA package and 10 W power rating structure as other members like the 1N1366, but differs in its specific Zener voltage breakdown point. These components are standard discrete semiconductors used in power electronics.

Replacement Considerations

Direct substitutes must match the 27 V Zener voltage, 10 W power rating, and DO-203AA stud mount package. Verify electrical characteristics such as impedance and temperature coefficient against the original datasheet to ensure functional equivalence in the specific circuit application.
