Product details

Overview

STL7N6F7 from STMicroelectronics is an N-channel 60 V, 21 mΩ typ. R_DS(on), 7 A continuous drain current Power MOSFET in PowerFLAT™ 2x2 package, utilizing STripFET™ F7 trench technology for low conduction loss and fast switching. It delivers high avalanche ruggedness and low Crss/Ciss ratio for EMI immunity in compact DC-DC converters and motor control stages.

For engineers reviewing the STL7N6F7 datasheet, STL7N6F7 pinout, STL7N6F7 application, or STL7N6F7 equivalent, key selection criteria include its 25 mΩ max R_DS(on) at V_GS = 10 V, 8 nC total gate charge, 52 °C/W junction-to-PCB thermal resistance, and suitability for space-constrained 5–24 V industrial power switches.

Technical Context

This MOSFET employs an enhanced trench gate structure that reduces both on-resistance and internal capacitance-achieving 420 pF C_iss, 215 pF C_oss, and only 16 pF Crss at V_DS = 30 V. Its low 2.3 nC Q_gs and 2.1 nC Q_gd enable precise timing control in high-frequency PWM circuits.

The device supports pulsed drain currents up to 28 A with safe operating area (SOA) defined for resistive and inductive loads. Its source-drain diode exhibits 1.2 V forward voltage at 7 A and 17.1 ns reverse recovery time under standardized 100 A/µs di/dt conditions.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BSC028N06NS3	R_DS(on) = 2.8 mΩ lower (22.2 mΩ typ.), Q_g = 10.5 nC - higher drive demand	Better efficiency at <5 A; less robust Crss/Ciss ratio (5.1 %) increases shoot-through risk in half-bridge	Prefer when board-level thermal budget permits lower R_DS(on) and gate driver can supply >100 mA peak
ON Semiconductor NTMFS4C09NT1G	R_DS(on) = 24.5 mΩ typ., Crss = 14 pF - slightly better EMI immunity but 12 % higher conduction loss	Identical PowerFLAT™ 2x2 footprint and pinout; validated for automotive AEC-Q101	Select for automotive-qualified designs where qualification traceability outweighs 0.15 W extra loss at 7 A

Compared with BSC028N06NS3 and NTMFS4C09NT1G, STL7N6F7 offers the best balance of low gate charge (8 nC), industry-leading Crss/Ciss ratio (3.8 %), and proven avalanche ruggedness-making it optimal for cost-sensitive industrial switching where reliability under transient stress is critical.

FAQ

What is the maximum allowable PCB temperature for continuous 7 A operation?

The datasheet specifies 7 A continuous drain current at T_pcb = 25 °C and 4.5 A at T_pcb = 100 °C. For sustained 7 A operation, the PCB must be actively cooled or designed with ≥1 in² 2 oz Cu copper pour to maintain local board temperature ≤25 °C near the device footprint.

Does STL7N6F7 require a gate resistor for stability in half-bridge configurations?

Yes-a 4.7 Ω gate resistor is used in the official switching time test circuit (Figure 13). Due to its low Crss (16 pF), the device remains stable with values from 2.2 Ω to 10 Ω; values below 2.2 Ω may induce ringing during turn-off in high-dV/dt environments.

Can STL7N6F7 replace through-hole TO-220 MOSFETs in existing designs?

No direct drop-in replacement: STL7N6F7 uses PowerFLAT™ 2x2 (2 mm × 2 mm) surface-mount packaging with six terminals and an exposed drain pad. Retrofitting requires PCB redesign, thermal via placement under the pad, and gate drive layout optimization for high-frequency operation.

Is the source-drain diode body diode rated for continuous conduction?

The body diode is characterized for pulsed operation (300 µs pulse, 1.5 % duty cycle) with V_SD = 1.2 V and t_rr = 17.1 ns. Continuous conduction is not rated; use external Schottky or synchronous rectification for >10 % duty-cycle freewheeling paths.
