Product Description
Vishay 1N4148W-E3-08 switching diode is a high-performance single silicon junction switching diode designed for electronic applications requiring fast switching and high reliability.
This diode supports a maximum forward current of 150 mA and a peak reverse repetitive voltage of 75 volts, making it suitable for applications such as high voltage rectification, snubber circuits for camera flashes, and grid control in CRT and TV devices.
The device is built with a superectifier structure and a cavity-free glass passivated junction to ensure durability and low leakage current, typically under 0.2 μA. It is engineered for operation within a temperature range of -55°C to 150°C, enhancing its robustness in demanding environments.
Encapsulated in a compact SOD-123 surface mount package measuring 2.85 mm in length, 1.7 mm in width, and 1.25 mm in height, the diode’s physical attributes enable easy integration into modern PCB designs. The matte tin plated terminals are solderable according to J-STD-002 and JESD 22-B102 standards, ensuring reliable electrical connections.
The 1N4148W-E3-08 variant meets RoHS compliance and is commercially graded, with the E3 suffix indicating compliance to whisker test standards JESD 201 class 1A. The device does not carry automotive certification and originates from China.
