Vishay Silicon Junction Switching Diode Single 200 mA 50 V MicroMELF MCL4151-TR

Vishay MCL4151-TR is a high-reliability silicon junction switching diode designed for surface-mount applications in electronic circuits requiring fast switching and low losses. It supports a maximum forward current of 200 mA and a peak reverse voltage of 50 V, packed in a MicroMELF package with dimensions 2 mm length and 1.2 mm width and height.

The device features a glass passivated junction with a cavity-free structure that ensures excellent electrical performance and durability. Its fast switching speed is characterized by a peak reverse recovery time of only 4 nanoseconds, making it ideal for switching power supplies and signal processing circuits.

This diode exhibits a low typical leakage current of less than 0.2 microamperes, reducing energy consumption and thermal dissipation. The high forward surge current rating of 2 A provides robustness against transient load spikes. The terminals are matte tin plated and comply with solderability standards J-STD-002 and JESD 22-B102 for reliable assembly.

Operating reliably across a wide temperature range from −65°C to 175°C, the MCL4151-TR supports applications in harsh environments including industrial electronics and consumer devices. It is commonly used for high voltage rectification in G2 grid CRT and TV circuits and as a snubber diode in camera flash units.

The MicroMELF packaging ensures a compact footprint with epoxy molding compound meeting UL 94 V-0 flammability rating. The color band on the diode denotes the cathode end for correct polarity installation.

Glass passivated junction ensures enhanced reliability and performance. Cavity-free construction reduces internal defects for greater efficiency. Fast switching capability with 4 ns peak reverse recovery time. Low leakage current typically below 0.2 μA for minimal power loss.

High surge current tolerance up to 2 A for peak loads. Compact MicroMELF package dimensions: 2 mm length, 1.2 mm width and height. Matte tin plated leads are solderable and compliant with J-STD-002. Wide operating temperature range from −65°C to 175°C suitable for diverse applications.

Color band marking indicates cathode for correct polarity orientation.
