Product Description

Vishay MCL4148-TR3 is a high reliability silicon junction switching diode designed for surface mount technology with a MicroMELF (DO-204AL) package. The diode supports a maximum forward current of 150 mA and a maximum peak reverse repetitive voltage of 100 V. Its fast switching capability with an 8 ns peak reverse recovery time makes it suitable for high efficiency and fast switching applications.

Equipped with a cavity-free glass passivated junction and molded epoxy over glass body, this diode ensures durability and stable performance in industrial and electronic manufacturing environments. Its matte tin plated leads provide excellent solderability compliant with J-STD-002 standards. The diode’s operating temperature ranges from -65°C to 175°C, enabling use in demanding temperature conditions.

The device features a low leakage current typical IR < 0.2 μA and a high forward surge capability with the ability to withstand 2 A peak non-repetitive forward surge current. Polarity is clearly marked with a color band denoting the cathode end to facilitate correct installation.

Typical applications include high voltage rectification of G2 grid in CRT and TV sets, and snubber circuits in camera flash units where fast switching and reliability are critical. The MicroMELF compact 2-pin form factor supports space-saving designs in electronic assemblies.

Single silicon junction diode with MicroMELF surface mount package. 150 mA maximum forward current and 100 V peak reverse voltage for medium power circuits. Fast switching with 8 ns peak reverse recovery time. Low leakage current and robust forward surge capability.
