1N3015A

Overview

The Microchip Technology 1N3015A is a high-power Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 200 V with a tolerance of ±5%. The device has a maximum power dissipation rating of 10 W and operates within a temperature range of -65 °C to +175 °C. It utilizes a stud mount package (DO-213AA) suitable for chassis mounting.

Feature Summary

• Provides stable voltage regulation across a broad range using silicon junction technology
• Capable of handling high power dissipation for robust performance in demanding environments
• Designed for military qualification levels including JAN, JANTX, and JANTXV

Applications

• High voltage power supply regulation
• Overvoltage protection circuits
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the specific suffix (e.g., A, B) matches the required voltage tolerance and regulatory compliance level. Confirm that the DO-213AA stud mount package aligns with the thermal management and mechanical design of the target PCB or chassis assembly before finalizing orders.

Selection Notes

Select this component when a precise 200 V reference is needed with high power handling capabilities. Ensure the application can accommodate the stud mount form factor and provides adequate heat sinking to maintain operation within the specified temperature limits under full load conditions.

Part Context

This part belongs to the JEDEC registered 1N2970B through 1N3015B series of 10 W Zener diodes. These devices are widely used in applications requiring reliable voltage regulation at higher voltages up to 200 V, offering a standardized solution for power electronics and industrial control systems.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N3015A equivalents such as those from Naina Semiconductor or Solid State, provided they meet the same 200 V, 10 W, and DO-213AA package specifications.
