The MBRT30040RL is a diode rectifier array from Marking Technologies, which is a series of high-performance fast-recovery rectifiers optimized for kick-back spike or reverse-recovery time. This device provides several mounting configurations for versatile solutions, in addition to its wide operating junction temperature range. This article will discuss the application field and working principle of MBRT30040RL.

The MBRT30040RL diode rectifier array is designed to be used in power semiconductor and bridge rectifier applications in motor control inverters, lighting, renewable energy and battery charging equipment. It can also be used in DC-DC converters and various switching power supplies. Furthermore, it is suitable for high ac current, medium frequency (100 KHz) hard switching circuits and can hold off high continuous current, 200 Amp di/dt.

In terms of its working principle, the MBRT30040RL has two transistors that work both in drive and protection functions. The drive transistor is connected in parallel to ground while the protection transistor is connected in series and is capable of passing current bidirectionally. When the forward voltage increases, the drive transistor starts to conduct and the protection transistor starts to inhibit conduction. This arrangement allows low reverse leakage (IR) and short recovery time (trr).

In addition, the MBRT30040RL has an extra low thermal resistance module and a metal oxide semiconductor field-effect transistor (MOSFET) compliant design. The extra low thermal resistance allows for improved cooling during high power operation and the MOSFET compliant design ensures compatibility with tight switching frequency specifications.

To summarize, the MBRT30040RL diode rectifier array from Marking Technologies is optimized for kick-back spike or reverse-recovery time and is a great choice for a wide range of applications including power semiconductor, bridge rectifier, DC-DC converters, switching power supplies and more. Its working principle involves two transistors, one in drive and one in protection, both with low resistance and short recovery time. Furthermore, the extra low thermal resistance module and the MOSFET compliant design make it a reliable choice.
