STL150N3LLH6 Description

The STL150N3LLH6 from STMicroelectronics is an N-channel 30V, 150A power MOSFET designed for high-efficiency power management applications. Part of the DeepGATE™ and STripFET™ VI series, it leverages advanced Metal Oxide (MOSFET) technology to deliver ultra-low Rds(on) of 2.4mΩ at 10V Vgs, minimizing conduction losses. Packaged in a PowerFlat™ (5x6), this surface-mount device is optimized for high-current switching in compact designs. Though marked Obsolete, it remains a robust choice for legacy systems requiring high power density and thermal performance, with a maximum power dissipation of 80W (Tc).

STL150N3LLH6 Features

• Low On-Resistance: 2.4mΩ @ 16.5A, 10V ensures minimal power loss in high-current paths.
• High Current Handling: 150A continuous drain current (Tc) supports demanding loads.
• Fast Switching: Gate charge (Qg) of 40nC @ 4.5V and input capacitance (Ciss) of 4040pF @ 25V enable efficient high-frequency operation.
• Robust Gate Drive: Vgs(max) of ±20V and threshold voltage (Vgs(th)) of 1V @ 250µA ensure reliable control.
• Compact Packaging: PowerFlat™ (5x6) offers superior thermal resistance and space savings.
• Compliance: ROHS3 and REACH Unaffected, with MSL 1 (Unlimited) for extended shelf life.

STL150N3LLH6 Applications

• DC-DC Converters: Ideal for synchronous buck/boost topologies due to low Rds(on) and high current capability.
• Motor Drives: Efficiently controls high-power brushed/BLDC motors in automotive and industrial systems.
• Power Supplies: Suits server/telecom PSUs requiring high efficiency and thermal stability.
• Battery Management: Used in discharge protection circuits for Li-ion packs in EVs and energy storage.
• Load Switches: Enables fast switching in hot-swap and ORing applications.

Conclusion of STL150N3LLH6

The STL150N3LLH6 excels in high-current, low-voltage applications where minimized conduction losses and compact footprint are critical. Its DeepGATE™ technology and PowerFlat™ package make it a standout for legacy designs needing reliability in thermal management and power density. While obsolete, its performance metrics—such as 150A Id and 2.4mΩ Rds(on)—ensure it remains viable for replacements in industrial, automotive, and power electronics systems.
