CDBF0245-HF

Introduction to CDBF0245-HF Single Rectifiers

Single rectifiers are semiconductor devices capable of converting alternating current (AC) to direct current (DC). The CDBF0245-HF is a single rectifier manufactured by NXP Semiconductors, designed for applications requiring a short recovery time, low forward voltage drop and low leakage current.

Construction

The CDBF0245-HF is packaged in a single-leads 3 mm x 3 mm package made from UL-94V-0 thermoplastic with a tin-plated lead-frame. The package includes a cathode, an anode and a grounded gate. The core of the device is the rectifying element, either a p-n junction or Schottky diode. The purpose of the gate is to control current conduction and reverse voltage protection. The anode and cathode connections connect to the circuit system, and the gate connects to the device control circuit.

Specifications

The most important spec for a single rectifier is Reverse Voltage (VRRM), which defines the maximum voltage the device can handle in reverse current conduction. The CDBF0245-HF has a maximum reverse voltage rated at 200 volts. The device also has a maximum current rating of 40 mA, a forward voltage drop of 1.2 V max and a maximum leakage current of 5-25 mA. The reverse recovery time is 50 ns.

Circuit Design

When designing a circuit with a single rectifier, the following factors must be taken into consideration: size and power requirement, leakage current, forward voltage drop, surge, frequency and temperature. The CDBF0245-HF is suitable for applications with a power requirement of up to 200 W. The most suitable circuit type to use with the device is a parallel bridge rectifier. The advantage of this type of design is that the voltage and current requirements are easily met. The circuit can also be used in applications where low reverse recovery time is required.

Applications

The CDBF0245-HF is suitable for a wide range of applications, including power supplies, rectifying converters, invertors and other DC-DC converter circuits. It is also suitable for automotive applications, including automotive instrumentation and engine control systems. Other applications include portable systems, low-voltage systems, high switching frequency and high current systems.
