SiR5623DP-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power BMS protection board or industrial motor drive, facing a -60V bus voltage and tens of amperes of load current, but struggling with either high on-resistance or poor thermal dissipation of P-channel MOSFETs? The VBsemi SiR5623DP-VB is designed for this—it integrates -60V withstand voltage, -36A current capability, and an ultra-low on-resistance of 21mΩ into a compact DFN8(5X6) package, allowing high-voltage, high-current P-channel applications to no longer compromise between heat and space.

Domain and module applications：
- BMS Battery Protection Board – As a high-side discharge switch, quickly disconnects during overcurrent or short circuit, with ample voltage margin to protect battery cells.
- Negative Voltage Power Systems – Suitable for load switches and reverse polarity protection on -60V rails, low on-resistance reduces system voltage drop.
- Industrial Motor Drives – Leverages -36A high current capability and low RDS(on) for efficient H-bridge or high-side drive, reducing heat dissipation requirements.
- Power Tools and Garden Machinery – Handles high inrush current within a compact DFN8 package, offering excellent reliability and thermal performance.
- Telecom Base Station Power – Used for hot-swap and on/off control in -48V power distribution units, wide SOA ensures stable operation under harsh conditions.
- Automotive Electronics Auxiliary Power – Withstands vehicle power supply fluctuations, providing robust support for high-side switches and load management.
- DC-DC Converters – Used as synchronous rectifier in negative voltage buck-boost topologies, effectively improving conversion efficiency.
In a nutshell: The SiR5623DP-VB is not just an ordinary P-channel MOSFET; it is the "performance cornerstone" and "thermal management champion" for your high-voltage, high-current power supply designs.
