Product Description

Vishay MCL4148-TR is a silicon junction switching diode configured as a single diode in a compact MicroMELF 2-pin package. It supports a maximum forward current of 200 mA, forward voltage of 1 V, and maximum peak reverse voltage of 100 V, optimized for fast switching applications. Its cavity-free glass-passivated junction enhances reliability and performance in demanding electrical environments.

This diode provides excellent surge current capability with a peak non-repetitive forward surge current of 2 A, and a low typical leakage current of under 0.2 µA, making it suitable for use in precision electronic circuits. Operating in a broad temperature range from -65°C up to 175°C, it withstands harsh industrial and commercial conditions.

The MicroMELF package with dimensions approximately 2 mm in length and 1.2 mm diameter provides a space-saving form factor suitable for surface mount technology (SMT). The diode terminals are matte tin plated and comply with robust soldering standards, ensuring ease of manufacturing and long term durability.

Typical applications include high voltage rectification of G2 grids in cathode ray tubes (CRTs) and televisions, as well as snubber circuits in camera flash units and other switching circuits requiring reliable, fast switching semiconductor devices.

Superectifier structure ensures enhanced device reliability. Cavity-free glass-passivated junction prevents contamination and damage. Fast switching time of 8 nanoseconds optimizes circuit response. Low leakage current for efficient operation.

High forward surge current capability protects against transient conditions. Wide operating temperature range ensures versatility. Compact DO-204AL molded epoxy case in MicroMELF format saves PCB space. Color band marking denotes cathode end for correct polarity orientation.

Vishay's MCL4148-TR diode is ideal for industrial electronic applications, laboratory use, consumer electronics manufacturing, and various other fields requiring precision semiconductor switching components. It meets commercial grade RoHS compliance and solderability standards aligned with JEDEC protocols.
