403CNQ100 Discrete Semiconductor Products

The 403CNQ100 is a rectifier diode array designed to provide high-speed switching which is ideal for power supply circuits. It is intended for use in automotive and industrial applications such as stabilizers, overvoltage protection, and lighting. The array is composed of two diodes in Series configuration which provide a high surge current capability. It is designed with a low thermal resistance to reduce the power dissipation and improve the response time.

The 403CNQ100 is a 600 V 12 A forward drop, single phase, rectifier diode array. It operates at an operating temperature range from -55°C to +150°C and is available in either a standard lead frame package or a Pb-free SO-8 package. The superior reverse leakage current capabilities of this device makes it well suited for Reverse Current Protection (RCP) applications.

The 403CNQ100 works by providing a fast, reverse-recovery diode which serves to protect against over-voltage transients in the application. It is composed of two diodes in series with an electrostatic shield between them. The negative side of the shield provides galvanic isolation of the two diodes to improve the transient response. This device also features low on-state voltage drop, low reverse leakage current and a fast switching capability.

The working principle of a diode array, such as the 403CNQ100, involves a few simple steps. When a voltage is applied to the anode of the array, current flows through the positive half of the shield and through the positive diode. As the positive diode begins to conduct, the electric field of the anode-cathode junction is reversed, allowing a current to flow through the reverse path. This current triggers the reverse recovery process which is crucial for the protection of the application from over-voltage transients.

Once the current has been redirected, the voltage across the anode-cathode junction becomes zero and the current stops flowing. This allows for the protection of the application from damages due to over-voltage transients. This whole process happens in a fraction of a microsecond, allowing for fast response times and superior protection for sensitive electronics.

The 403CNQ100 is a versatile diode array which is suitable for a broad range of applications. It enables a wide range of voltage protection options, including overvoltage and reverse current protection. The superior protection characteristics of this device make it the ideal choice for automotive, industrial and lighting applications. Moreover, it is designed with a low thermal resistance to reduce power dissipation and improve response times.

In summary, the 403CNQ100 is a rectifier diode array which is ideal for automotive, industrial and lighting applications. It provides a high surge current capability with a low thermal resistance to improve response times. The array’s superior reverse leakage current capabilities make it well suited for reverse current protection applications. Additionally, it features a fast switching speed and an operating temperature range of -55°C to +150°C.
