1N4148 Switching Diodes

Taiwan Semiconductor 1N4148 Switching Diodes feature fast switching speed, high surge current capability, 150mA forward current, and high efficiency. These diodes offer up to 400W power dissipation and are available in a single-die configuration. The 1N4148 diodes are RoHS-compliant and halogen-free. These diodes are used in Switching Mode Power Supplies (SMPS), adapters, on-board DC-DC converters, and lighting applications.
