1N3010A

Overview

The Microchip Technology 1N3010A is a single Zener diode designed for stud mount applications. It features a nominal Zener voltage of 140 V with a 5% tolerance and a maximum reverse leakage current of 10 uA. The device operates within a temperature range of -65°C to +175°C and dissipates up to 10 W of power. Packaged in a DO-213AA-2 case, it exhibits a Zener impedance of 125 Ohms at a test current of 18 mA. Key electrical characteristics include a forward voltage of 1.5 V at 2 A forward current and a voltage temperature coefficient of 0.095%/°C.

Feature Summary

• Provides stable voltage regulation through Zener breakdown characteristics in the reverse bias region.
• Capable of handling high thermal loads via stud mount installation for efficient heat dissipation.
• Operates reliably across an extended industrial temperature range from -65°C to +175°C.

Applications

• High-voltage reference circuits requiring stable regulation.
• Overvoltage protection systems in industrial equipment.
• Power supply voltage clamping applications.

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct package and testing specifications. Confirm that the DO-213AA-2 stud mount configuration matches your mechanical design requirements. Cross-reference the 140 V Zener voltage and 10 W power dissipation ratings with your circuit's thermal management plan to ensure compliance with operational limits.

Selection Notes

Select this component when a high-voltage Zener reference is required in a rugged environment. The wide operating temperature range supports demanding industrial conditions. Ensure the mounting surface accommodates the stud mount style for proper thermal contact. Verify that the 125 Ohm Zener impedance meets the noise and stability requirements of the target application circuit.

Part Context

The 1N3010A belongs to the standard Zener diode family manufactured by Microchip Technology. It utilizes the DO-213AA-2 package, which is distinct from smaller signal diodes due to its higher power handling capabilities. This series is categorized under Diodes & Rectifiers and is intended for applications requiring robust voltage regulation and high thermal stability.

Replacement Considerations

Consult official Microchip substitution guides or equivalent manufacturer datasheets for compatible parts. Verify that any substitute maintains the 140 V Zener voltage, 10 W power rating, and DO-213AA-2 package dimensions to ensure mechanical and electrical compatibility.
