SiJA54DP-VB Product details
Back to previous pageProduct introduction：
The SiJA54DP-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching applications. It utilizes advanced SGT technology to achieve an excellent balance between ultra-low on-resistance and superior switching performance. The LFPAK56 package strikes an ideal balance between heat dissipation capability and board space. The combination of 40V withstand voltage, 150A current carrying capacity, and 0.7mΩ on-resistance makes it a preferred alternative to traditional DPAK or D2PAK packaged devices in server power supplies, automotive electrical systems, and high-power-density modules, especially for applications with stringent thermal and efficiency requirements.

VDS=40V: Suitable for 12V/24V/36V systems, providing ample voltage margin for spikes, enhancing avalanche ruggedness and system reliability.
VGS=±20V: Compatible with a wide range of gate drive levels, can be directly connected to PWM controllers, MCUs, or dedicated driver ICs, simplifying interface design.
Vth=3V (Typical): Moderate threshold voltage offers good noise immunity while ensuring deep linear region operation with 10V drive, fully minimizing conduction losses.
RDS(on)=0.7mΩ @ VGS=10V: Ultra-low on-resistance drastically reduces full-load power dissipation, significantly decreasing the need for heat sink copper area and heatsinks.
ID=150A: Extremely ample continuous current capability, meeting peak current demands of heavy-load scenarios like high-power motors, battery switches, and power rectification.
Package LFPAK56: Low parasitic inductance, low thermal resistance, supports high-density mounting, and offers excellent power cycling capability, suitable for compact high-current modules.
Domain and module applications：
Server & Telecom Power Supplies: Replaces Schottky diodes or multi-parallel solutions in synchronous rectification, significantly improving heavy-load efficiency and aiding power module miniaturization.
Power Tools & Low-Voltage Motor Drives: Ultra-low on-resistance withstands high current surges, low PWM switching losses result in smoother motor operation and significantly lower controller temperature rise.
Battery Protection & BMS: Microsecond fast switching combined with 150A high current margin handles high-rate charge/discharge protection, reducing self-heating of the protection board.
Automotive Electrical Systems: 40V withstand voltage covers 12V/24V vehicle bus transient requirements. Wide operating temperature range and high reliability suit harsh environments like engine compartments and body control.
DC-DC Converters: Extremely low RDS(on) minimizes conduction losses, SGT technology optimizes switching waveforms, suitable for high-frequency synchronous buck/boost topologies.
High-Power Load Switches: Supports hot-swap, power path management, and industrial equipment power distribution, replacing multiple paralleled devices with a single component, simplifying design and reducing cost.
Selection Summary: The SiJA54DP-VB, with its ultra-low on-resistance, high current capability, and compact LFPAK56 package, provides a high cost-performance solution for 40V low-voltage, high-current applications, particularly suitable for projects with extreme demands on efficiency, thermal performance, and power density.
