84CNQ035S2

The 84CNQ035S2 is a high-temperature and high-power rectifier diode module, belonging to the Rectifiers - Arrays family of diodes. The diode module is a 4-pin package, typically in an 8mm x 16mm discrete package. The 84CNQ035S2 can also be used as a three-phase rectifier, with an encapsulated housing and a four-pin connection header.

The 84CNQ035S2 has a wide range of operating temperatures, from -55℃ to +150℃, and an operating voltage range of up to 1200V. It has excellent surge capability, providing higher peak avalanche and reverse (blocking) voltage for increased safety and reliability. Its low thermal resistance ensures high efficiency and performance at high frequencies.

The 84CNQ035S2 application field includes power modules, DC/AC converters, and battery chargers. It is suited for use as a bridge, half-wave, full-wave, bridge-tied load (BTL), or other type of rectifier. It can also be used as a protective component in AC/DC circuits, and it offers an integrated back-EMF diode, helping reduce ringing and noise in the circuit.

When used as a bridge rectifier, the 84CNQ035S2 consists of four diodes connected together in a bridge circuit configuration. When one of the four diodes is forward biased, the other three diodes are reverse-biased, allowing current to flow through only one diode. The diode module can then be used to rectify AC current, converting it to DC current.

In terms of working principle, the 84CNQ035S2 is a forward-biased diode that utilizes the “rectifying effect” of a p-n junction. When electrical current flows from the anode to the cathode, one of the diodes connected to the bridge will be forward-biased, allowing current to pass through that particular diode. When the current tries to flow in the opposite direction, the same diode will be reverse-biased, blocking the current and preventing it from flowing.

To summarize, the 84CNQ035S2 diode module is a high-power and high-temperature rectifier that is suited for many different applications. It is a 4-pin package with a wide temperature range, 1200V of voltage, and excellent surge capability. It is typically used as a bridge, half-wave, full-wave, bridge-tied load (BTL), or other type of rectifier. It works through the “rectifying effect” of a p-n junction, and it is often used to convert AC current to DC current.
