Reinforced Gate Driver Transformer – SM91243L Series

Bourns SM91243L reinforced gate driver transformers have been developed for use with the Allegro Micro Model AHV85000 and AHV85040 GaN FET isolated gate driver chipsets. This gate driver transformer provides very low interwinding capacitance (Ciw) and leakage inductance (Lk). The design for manufacturing (DFM) overmolding process delivers a compact size with reinforced insulation, manufactured with a fully automated process to ensure high quality and cost effectiveness. The device provides a 10 mm minimum clearance and creepage distance with reinforced insulation, a working voltage up to 1,000 V, and a hi-pot isolation voltage up to 5,000 V_AC with an extended operating temperature range of -40°C to +125°C.
