1N2810B

Overview

The Microchip Technology 1N2810B is a single Zener diode with a nominal reference voltage of 12V and a maximum voltage tolerance of 5%. It features a maximum power dissipation of 50W and operates at a test current of 1000 mA. The component has a maximum dynamic impedance of 1Ω and supports a highest operating temperature of 175°C. It utilizes tin/lead (Sn/Pb) terminal plating and is not surface mountable.

Applications

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

Procurement Notes

Verify RoHS compliance status, as the component is listed as non-compliant. Confirm package type compatibility for through-hole mounting. Ensure thermal management solutions support the 50W power dissipation rating. Validate terminal plating specifications against soldering requirements. Check manufacturer documentation for specific handling instructions regarding leaded components.

Selection Notes

Select this component when high power handling capability is required for voltage clamping applications. The 12V nominal voltage suits specific regulation needs. Consider the 175°C operating temperature limit for high-thermal environments. Evaluate the need for through-hole installation versus surface-mount alternatives. Verify that the 5% tolerance meets circuit precision requirements.
