My old doorbell stopped working because of corrosion after years of being exposed to the elements. I replaced the doorbell but also needed a new diode. The FAIRCHILD SEMICONDUCTOR 1N4003 DIODE worked as advertised and allows my doorbell to finish its tune after I release the button.

### ⭐⭐⭐⭐⭐ Values are Consistant
*by M***N on August 27, 2025*

I ordered the 5 pack Fairchild IN4003 diodes to have as a spare replacement part for the OEM diode in my Class B Solis Pocket 36A Camper Van for the House Battery 12VDC charging solenoid coil. The measured values of the Fairchild diodes (5 pack) were pretty close to the original OEM diode reverse polarity megohms (+/- 2.5MEGOHM) and reverse polarity voltage drop (0.55 volts). I made a diode assembly with a terminal block, leads, crimp connectors, and heat shrink so as to be able to quickly replace on the road if the original diode fails. I used liquid rubber to encapsulate and waterproof the diode assembly.
