Vishay LL4148-GS18 is a high-quality silicon junction switching diode, supplied in a MiniMELF DO-204AL package, designed for surface mounting and fast switching applications. It supports a maximum forward current of 300 mA and a peak surge current of 2 A, making it suitable for precision rectification and snubber circuits in electronic devices.
The diode features a glass-passivated junction with a superectifier structure that enhances reliability and reduces leakage current to less than 0.2 μA, ensuring stable performance over a wide temperature range from -65°C to 175°C. Its fast recovery time of 8 ns enables efficient operation in high-frequency circuits.
This product is widely used in high voltage rectification tasks such as G2 grid CRTs, TV circuitry, and camera flash snubber circuits. The MiniMELF package dimensions (1.6 mm diameter × 3.7 mm length) provide a compact footprint, ideal for space-constrained designs.
The DO-204AL molded epoxy glass body offers mechanical robustness, and matte tin-plated leads facilitate reliable soldering conforming to J-STD-002 and JESD 22-B102 standards. The diode polarity is marked by a color band indicating the cathode end for correct installation.
It also meets the automotive industry's AEC-Q101 standard, ensuring suitability for automotive electronics requiring high durability. Superectifier structure for high reliability. Low leakage current with glass-passivated junction.
High forward surge capability up to 2 A. Compact MiniMELF DO-204AL package. Fast switching with 8 ns recovery time. Wide operating temperature range from -65°C to 175°C. Matte tin-plated solderable leads. Automotive standard AEC-Q101 certified.
This Vishay switching diode is ideal for industrial, electronic manufacturing, automotive, and laboratory applications requiring reliable and fast diode switching components.
