Product details
Overview
STH140N6F7-2 from STMicroelectronics is an N-channel 60 V, 80 A, 110 W Power MOSFET in H2PAK-2 package, featuring 0.0025 Ω typ. RDS(on), 100% avalanche tested design, and STripFET™ VII DeepGATE™ technology. It serves as a high-current switching device in DC-DC converters, motor drives, and industrial power supplies where low conduction loss and thermal robustness are critical.
For engineers reviewing the STH140N6F7-2 datasheet, STH140N6F7-2 pinout, STH140N6F7-2 application, or STH140N6F7-2 equivalent, this page delivers verified electrical ratings, package-specific thermal data, gate charge metrics, source-drain diode performance, and real-world switching behavior under resistive and inductive loads.
Technical Context
This MOSFET employs ST's 7th-generation STripFET™ process with DeepGATE™ gate architecture to minimize RDS(on) while maintaining ruggedness. Its H2PAK-2 package delivers 1.36 °C/W junction-to-case thermal resistance and supports 80 A continuous drain current at TC = 100 °C.
The device exhibits 2700 pF input capacitance (Ciss) and 25 pF reverse transfer capacitance (Crss) at VDS = 25 V, enabling fast switching with 40 nC total gate charge. Its source-drain diode sustains 80 A continuous and 320 A pulsed current with controlled reverse recovery characteristics.

FAQ
What is the maximum continuous drain current for STH140N6F7-2 at 100°C case temperature?
The STH140N6F7-2 supports 80 A continuous drain current at TC = 100 °C, as specified in Table 2 of the datasheet (DocID025089 Rev 1). This rating is enabled by its H2PAK-2 package's 1.36 °C/W junction-to-case thermal resistance and 110 W total power dissipation at 25 °C case temperature.
Does STH140N6F7-2 have integrated avalanche ruggedness?
Yes-STH140N6F7-2 undergoes 100% production avalanche testing per the datasheet's "Features" section. This confirms its ability to withstand unclamped inductive switching (UIS) events without degradation, a critical requirement for motor drive and converter applications with reactive loads.
How does the H2PAK-2 package compare thermally to TO-220FP for this MOSFET?
H2PAK-2 provides 1.36 °C/W junction-to-case thermal resistance versus 5 °C/W for TO-220FP (Table 3), enabling significantly higher power handling. At identical 80 A current, H2PAK-2 reduces junction temperature rise by ~360 °C·W compared to TO-220FP-directly supporting higher ambient or smaller heatsinks.
Can STH140N6F7-2 be used in synchronous rectification topologies?
Yes-its 0.0025 Ω typ. RDS(on), low 25 pF Crss, and fast intrinsic body diode (trr not specified but characterized per Figure 4) make it suitable for synchronous rectification in buck, LLC, and active clamp forward converters operating up to 500 kHz, provided gate drive timing avoids shoot-through.
