General Description

FSBM20SL60 is an advanced smart power module (SPM) that Fairchild has newly developed and designed to provide very compact and high performance ac motor drives mainly targeting low speed low-power inverter-driven application like air conditioners. It combines optimized circuit protection and drive matched to low-loss IGBTs. Highly effective short-circuit current detection/protection is realized through the use of advanced current sensing IGBT chips that allow continuous monitoring of the IGBTs current. System reliability is further enhanced by the integrated undervoltage lock-out protection.

Features

• UL Certified No. E209204

• 600V-20A 3-phase IGBT inverter bridge including control ICs for gate driving and protection
