Frequently Asked Questions
What is the maximum drain current and breakdown voltage of the A1TB45W65M5-FC?
The A1TB45W65M5-FC supports a maximum drain current (ID) of 25 A and a minimum drain-source breakdown voltage of 650 V, making it suitable for high-voltage boost PFC and AC-DC conversion stages operating from universal mains input up to 264 VAC.
How does the integrated SiC diode in the A1TB45W65M5-FC improve boost PFC efficiency?
The integrated Silicon Carbide (SiC) diode offers near-zero reverse recovery charge, significantly reducing switching losses at frequencies above 65 kHz compared to conventional silicon diodes. This allows the A1TB45W65M5-FC to achieve higher switching frequencies with lower thermal dissipation in boost PFC topologies.
Which industrial or EV charging applications are best suited to the A1TB45W65M5-FC ACEPACK 1 module?
The A1TB45W65M5-FC is ideal for EV on-board charger (OBC) front-end PFC stages operating at 650 V, industrial AC-DC power supplies rated above 1 kW, telecom rectifiers, and solar string inverters. Its 0.068 Ω on-resistance and ACEPACK 1 isolated package deliver efficient thermal management in compact high-power designs.
What package does the A1TB45W65M5-FC use and how does it simplify PCB integration?
The A1TB45W65M5-FC comes in the ACEPACK 1 power module package (JESD-30 code R-XUFM-X18), which integrates 3 power elements including MOSFET, SiC diode, and NTC thermistor in a single isolated housing. This integration reduces PCB footprint, external component count, and simplifies gate drive and thermal interface design for power densities above 2 kW.
