IXTP96N15T

The IXTP96N15T is optimized for low-voltage high-current applications, particularly synchronous rectification in DC-DC converters and SMPS. Its ultra-low 6.5mΩ Rds(on) minimizes conduction losses at high currents, making it ideal for: (1) 48V server power supplies - excellent for 12V output synchronous rectifiers; (2) Battery chargers - high efficiency at high charging currents; (3) Telecom rectifiers - 48V to intermediate bus conversion; (4) Motor drives - low-voltage high-current motor control. The 150V rating provides adequate margin for 48V systems with transients. For applications above 75A continuous, ensure adequate heatsinking as conduction losses become significant.

Best for synchronous rectification in 48V systems and high-current DC-DC converters.

To minimize switching losses with IXTP96N15T at high frequencies: (1) Gate drive - use low-impedance gate driver (2A+ capability) with proper gate resistor (5-10Ω); (2) Drive voltage - use 10-12V gate drive for optimal switching speed; (3) Layout - minimize gate loop inductance (<10nH) and drain-source loop inductance; (4) Snubbers - consider RC snubbers if voltage overshoot exceeds 80% of Vds rating; (5) Dead time - in bridge configurations, minimize dead time to reduce body diode conduction. At 100kHz, switching losses are typically 10-15W. For frequencies above 200kHz, consider using resonant topologies or advanced soft-switching techniques to minimize switching losses.

Use strong gate drive and optimize layout for minimal switching losses at high frequencies.

Without a heatsink, the IXTP96N15T in TO-220 package has limited power handling: (1) Thermal resistance junction-to-air Rth(j-a) is approximately 62°C/W for free air mounting; (2) Maximum junction temperature is 175°C; (3) At 25°C ambient, maximum power dissipation = (175-25)/62 = 2.4W; (4) At 50°C ambient, maximum power = (175-50)/62 = 2.0W. This limits continuous current to approximately 19A at 25°C ambient (P = I² × Rds(on) = 19² × 0.0065 = 2.35W). For higher currents, a heatsink is mandatory. Even a small heatsink (Rth = 20°C/W) increases capability to 6W, supporting 30A continuous operation.

Use heatsink for currents above 15A; free-air operation limited to ~2W dissipation.

Yes, the IXTP96N15T can be paralleled for higher current applications: (1) Current sharing - use individual gate resistors (1-2Ω) for each MOSFET to prevent oscillations; (2) Layout - ensure symmetric layout with equal trace lengths and impedances to each device; (3) Matching - devices from same production batch typically match within 10% for Rds(on); (4) Temperature - thermal coupling helps balance currents as Rds(on) increases with temperature; (5) Gate drive - use single gate driver with sufficient current capability (4A+ for two devices). Two IXTP96N15T in parallel can handle 150-170A continuous with proper heatsinking. Always verify current sharing with current probes during prototype testing.

Can be paralleled with proper gate resistors and symmetric layout for 150A+ applications.

Proper PCB layout is critical for IXTP96N15T performance: (1) Gate drive loop - minimize loop area between gate driver and MOSFET gate/source; keep traces short and wide; (2) Power loops - minimize inductance in high di/dt paths; use copper planes for drain and source connections; (3) Kelvin connection - use separate source connection for gate drive return to avoid source inductance feedback; (4) Decoupling - place ceramic capacitors (100nF-1µF) close to drain and source terminals; (5) Thermal vias - use thermal vias under the drain pad to spread heat to inner layers. Poor layout can cause voltage overshoots, oscillations, and increased switching losses. Follow IXYS application notes for recommended layouts.

Minimize gate and power loop inductance; use Kelvin source connection and adequate thermal vias.
