MOSFET H-bridges optimize DC fan and inverter designs

DALLAS, USA: Diodes Inc., a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, has announced a range of four H-bridge MOSFET packages that are set to dramatically simplify DC fan and Cold Cathode Fluorescent Lamp (CCFL) inverter circuits by reducing both component count and PCB size in space constrained applications.

Two 30V H-bridges, the ZXMHC3A01N8 and ZXMHC3F381N8, are well-suited for 12V DC fan and inverter applications and offer users a choice of low RDS(ON) performance. The 60V rated ZXMHC6A07N8 and 100V rated ZXMHC10A07N8 are industry firsts and are targeted at 24V DC and 48V DC motor control circuits, respectively.

Featuring dual complementary pairs of N- and P-type MOSFETs in an SO8 package, the ZXMHC parts can replace either four discrete SOT23 packaged MOSFETs or two SO8 complementary MOSFET packages.

The proprietary packaging enables significant reductions in the PCB footprint by at least 50 percent and in overall inventory cost for a wide range of existing motor or other inductive load drives.
