STMicroelectronics’ MDmesh DM6 600 V MOSFETs contain a fast-recovery body diode to bring the performance advantages of the company’s latest super-junction technology to full- and half-bridge topologies, zero-voltage switching (ZVS) phase-shift converters, and applications and topologies generally that need a robust diode to handle dynamic dV/dt.
Leveraging ST’s advanced carrier-lifetime control technology, these MOSFETs have reduced reverse-recovery time to minimise power dissipation in the diode when turning off after freewheeling. Recovery softness is optimised to enhance reliability. In addition, very low gate charge and on-resistance, together with a capacitance profile tailored for light loads, allow higher operating frequencies and greater efficiency, with simplified thermal management and reduced EMI.
Ideal for equipment such as charging stations for electric vehicles, telecom or data centre power converters, and solar inverters, the MDmesh DM6 family comprises 23 part numbers covering current ratings from 15 A to 72 A, with gate charge ranging from 20 nC to 117 nC and RDS(ON) from 0,240 Ω down to 0,036 Ω, respectively.
The choice of popular power package options includes the new low-inductance leadless TO-LL, PowerFLAT 8x8 HV, D2PAK, TO-220, and TO-247 with short leads, long leads or Kelvin pin for applications requiring precision current sensing.
