Bourns HVMA03F45A-ST8S Gate Driver Transformers
Bourns HVMA03F45A-ST8S Gate Driver Transformers are automotive-grade, AEC-Q200-compliant devices with an 8mm creepage distance and an 850V working voltage. These features make Bourns HVMA03F45A-ST8S transformers ideal for electric vehicle (EV) applications that require a high isolation voltage. These gate driver transformers have a wide operating temperature range from -40°C to +125°C for Class F operation. The high-creepage, SMT package provides a small footprint for a large working voltage. The HVMA03F45A-ST8S features a switching frequency of 50kHz to 380kHz and delivers up to 3W of output power. Typical automotive applications include gate-drive power for transistors, powering battery management circuits, and providing isolated power across separate voltage systems in hybrid vehicles.
