Category: Diodes, Electronics, Shindengen Electric Manufacturing Co Ltd

Overview

The datasheet details the specifications and characteristics of the Super Fast Recovery Diode, model DIFL4O. This component is designed for surface mount applications and boasts a series of features suitable for fast switching power supply systems and high-frequency noise-sensitive circuits.

Key Features

Highlighted features include low noise, super fast recovery time (trr) of 50ns, and high efficiency in a small SMD (Surface-Mount Device) package. Its applications span across a variety of sectors, including switching regulators, DC/DC converters, home appliances, office automation, lighting, communication, and factory automation.

Absolute Maximum Ratings

The diode’s absolute maximum ratings outline the limits beyond which the device may suffer irrevocable damage. These include a storage temperature range from -55°C to +150°C, an operating junction temperature of up to 150°C, a maximum reverse voltage (V_R) of 400V, an average rectified forward current (I_O) of 0.8A on an alumina substrate (when used at a standard ambient temperature of 25°C), and a peak surge forward current (I_fsm) of 25A under specified conditions.

Electrical Characteristics

The electrical characteristics table specifies the forward voltage (VF) at 0.8A as a maximum of 1.3V, the reverse current (IR) at maximum reverse voltage (VR = VRM) as 10μA, and the reverse recovery time (trr) as maximum 50ns when measured with a specified test condition. Thermal resistance from the junction to lead on alumina substrate is 6.3°C/W and from the junction to ambient on the glass-epoxy substrate is 108°C/W.

Characteristic Diagrams and Additional Information

The datasheet also includes various characteristic diagrams that depict the relationships between forward voltage and forward power dissipation, average rectified forward current, and other operational parameters like ambient temperature and number of cycles. These diagrams aid users in understanding how the diode performs under different conditions.
