SIR5623DP-T1-RE3-VB Product details
Back to previous pageProduct introduction：
The SIR5623DP-T1-RE3-VB is a Single P-MOS optimized for high-side power switch applications. The Trench process balances low switching losses with high reliability, and the DFN8(5X6) package achieves an excellent balance between heat dissipation and board space. The combination of 60V withstand voltage, 36A current capability, and 21mΩ on-resistance makes it an ideal high-performance alternative to traditional DPAK or SOP-8 packaged devices, especially suitable for high-density, high-current applications.

- VDS=-60V: Suitable for 12V/24V/48V systems, providing ample margin for negative voltage spikes, reducing avalanche breakdown risk.
- VGS=±20V: Compatible with 1.8V~12V logic levels, can be directly driven by MCU/PMIC, eliminating level-shifting circuits.
- Vth=-1.7V (typical): Low threshold voltage ensures full conduction even with negative gate drive, suitable for battery voltage decay scenarios.
- RDS(on)=21mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces full-load temperature rise, can reduce heat sink copper area.
- ID=-36A: Ample continuous current margin to handle peak demands of most automotive and industrial auxiliary loads.
- Package DFN8(5X6): Low parasitic parameters, excellent thermal resistance, supports high-frequency switching, saves PCB area and increases power density.
Domain and module applications：
- Load Switches and Power Management: Low on-resistance improves system efficiency, negative voltage turn-off characteristic suits high-side switch applications, small package aids compact design.
- Battery Protection Modules: Fast response ensures microsecond-level turn-off during overcurrent/short circuit, low on-resistance reduces self-heating of the protection board.
- Negative Voltage Power Conversion: Provides low-loss path in reverse polarity protection and negative voltage rails, improving overall reliability and efficiency.
- Motor Drive Control: Low PWM switching losses, smoother motor operation, significantly lower controller temperature rise.
- Automotive Auxiliary Power: 60V voltage margin and wide operating temperature range suit 12V/24V automotive buses, high reliability.
- DC-DC Converters: Replaces less efficient devices in synchronous rectification or high-side switch applications, improving heavy-load efficiency by 2-3%, facilitating module miniaturization.
- Industrial Control Modules: Direct logic-level drive simplifies peripheral circuits, suitable for PLCs, VFDs, and other applications requiring high voltage and surge resistance.
Selection Summary: The SIR5623DP-T1-RE3-VB achieves a balance between withstand voltage, on-resistance, package size, and heat dissipation capability. It is a high-performance general-purpose choice for 60V negative voltage switch applications, particularly suitable for projects with strict requirements for high current, low loss, and compact layout.
