Quad MOSFET in H-Bridge for DC motor controls and Inverters

Diodes Inc. has unveiled H-Bridge MOSFET for dc motor control applications and for inverters
The exact applications more specifically suggested by the company are DC fan and Cold Cathode Fluorescent Lamp (CCFL) inverter circuits

Two 30V H-Bridges, the ZXMHC3A01N8 and ZXMHC3F381N8 with low on resistance MOSFETs is for 12V DC fan and inverter applications.
The 60V rated ZXMHC6A07N8 and 100V rated ZXMHC10A07N8 are made for 24V DC and 48V DC motor control circuits, respectively.

Available in 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.

Diode Inc. says its proprietary package reduces PCB footprint by at least 50% for a wide range of existing motor or other inductive load drives.
