IPD50P04P4L11ATMA1-VB Product details
Back to previous pageProduct introduction：
The IPD50P04P4L11ATMA1-VB is a Single P-MOSFET deeply optimized for low-voltage, high-current power switching applications. The Trench process balances low conduction losses with high switching speed, and the TO252 (DPAK) package strikes a good balance between heat dissipation capability and board-level area. The combination of 40V withstand voltage, -50A current capability, and 12mΩ on-resistance makes it a reliable choice for medium-to-low voltage negative polarity power paths, power management, and motor drive applications, particularly suitable for industrial-grade and automotive-grade systems with high requirements for thermal performance and current density.

VDS=-40V: Suitable for 12V/24V systems and various negative polarity switching topologies, providing ample margin for voltage spikes, enhancing system robustness.
VGS=±20V: Compatible with common logic level drives, flexible gate drive design, adaptable to various PWM controllers and gate driver ICs.
Vth=-2V (typical): Moderate threshold voltage ensures sufficient turn-on under strong drive while effectively suppressing false turn-on caused by negative voltage spikes.
RDS(on)=12mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces conduction losses compared to similar P-MOSFETs, resulting in lower temperature rise under high current, making thermal design easier.
ID=-50A: Ample continuous drain current margin, capable of handling harsh conditions like motor stall, startup surge, and load transients.
Package TO252: Compatible with standard DPAK pads, short heat dissipation path, low thermal resistance, suitable for direct PCB copper heat sinking, and easy for automated assembly.
Domain and module applications：
Automotive Power Management: Voltage margin and low on-resistance suitable for 12V/24V automotive buses, can be used for reverse polarity protection, load switches, and body control modules.
Motor Drive Control: P-channel topology simplifies high-side drive circuits, low PWM switching losses, smooth motor operation, significantly improved controller temperature rise.
Battery Protection and BMS: Low internal resistance reduces self-heating of the protection board; fast switching characteristics support reliable turn-off during overcurrent/short circuit, enhancing battery pack safety.
Power Path Switching: Suitable for dual-power supply, battery backup, and OR-ing circuits; low dropout and high current capability ensure uninterrupted system power supply.
Industrial Control Modules: Wide safe operating area and strong surge immunity, suitable for industrial scenarios like PLCs, inverter auxiliary power supplies, and solenoid valve drives.
Power Converters: Replaces some N-MOSFET combination schemes in low-voltage synchronous rectification or negative voltage conversion circuits, simplifying drive design and improving conversion efficiency.
Power Tools and Outdoor Equipment: High current carrying capability and DPAK heat dissipation advantages meet long-term reliability requirements under high load cycles.
Selection Summary: The IPD50P04P4L11ATMA1-VB achieves an excellent balance between voltage, on-resistance, and current capability. The TO252 package balances heat dissipation and manufacturing convenience. It is a cost-effective, general-purpose choice for 40V class P-channel power switching applications, particularly suitable for power supply, automotive, and industrial projects with clear requirements for low losses, high current handling, and high reliability.
