STL55NH3LL Description

Short technical summary and product information.

The STL55NH3LL from STMicroelectronics is a high-performance N-Channel MOSFET designed for demanding applications. It features a maximum drain-source voltage (Vdss) of 30V and a continuous current rating of 55A at the case temperature.

 

This MOSFET offers a low maximum on-resistance (Rds On) of 8.8mOhm when tested at 7.5A and 10V Vgs, ensuring efficient power transfer. The gate charge (Qg) is 12nC maximum at 4.5V Vgs, and the input capacitance (Ciss) is 965pF maximum at 25V Vds. The gate-source voltage (Vgs) can be as high as ±16V, with a threshold voltage (Vgs(th)) of 2.5V maximum at 250µA.

 

Packaged in an 8-PowerVDFN (PowerFlat™ 5x6) format, the STL55NH3LL is suitable for surface mounting. It operates within a temperature range of -55°C to 150°C (TJ) and has a maximum power dissipation of 60W (Tc). Its technology is based on advanced MOSFET (Metal Oxide) principles.

 

The STL55NH3LL is RoHS3 compliant and has an MSL rating of 1, indicating unlimited moisture sensitivity. It is suitable for various power management applications where high current and low on-resistance are critical.
