Product details

Overview

STL20N6F7 from STMicroelectronics is an N-channel Power MOSFET with 60 V V_DS, 4.6 mΩ typical R_DS(on) at V_GS = 10 V, 20 A continuous drain current at T_pcb = 25 °C, and PowerFLAT™ 3.3×3.3 HV package. It delivers high-efficiency switching in DC-DC converters, motor drivers, and load switches where low conduction loss and fast switching are critical.

For engineers reviewing the STL20N6F7 datasheet, STL20N6F7 pinout, STL20N6F7 application, or STL20N6F7 equivalent, key selection factors include its 66 pF Crss/Ciss ratio for EMI immunity, 25 nC total gate charge, 1.6 °C/W R_thj-case, unclamped inductive ruggedness, and thermal performance on FR-4 PCBs.

Technical Context

This device uses STripFET™ F7 trench-gate technology to achieve ultra-low R_DS(on) while minimizing Crss (66 pF) and Ciss (1600 pF), enabling clean turn-on/turn-off waveforms in hard-switched topologies. Its gate threshold voltage (2–4 V) supports standard 10 V gate drive, and the integrated source-drain diode exhibits 39.6 ns trr and 36 nC Q_rr under defined inductive recovery conditions.

The PowerFLAT™ 3.3×3.3 HV package features exposed drain pads on pins 5–8 and a thermally optimized layout with 42.8 °C/W R_thj-pcb on 1 in² 2 oz Cu FR-4, making it suitable for compact, high-power-density board-level designs without heatsinks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage for 48 V bus applications with margin
R_DS(on) typ.	4.6 mΩ at V_GS = 10 V, ID = 10 A - enables <1 W conduction loss at 20 A
Q_g	25 nC - determines gate driver power requirement and switching speed
C_rss/C_iss ratio	66/1600 pF = 0.041 - reduces Miller-induced shoot-through risk and EMI
R_thj-pcb	42.8 °C/W - defines temperature rise over ambient on standard PCB layout
trr / Q_rr	39.6 ns / 36 nC - impacts body diode commutation losses in synchronous rectification
V_GS(th)	2–4 V - ensures reliable enhancement-mode turn-on with TTL/CMOS-compatible drivers

Pinout & Package

STL20N6F7 is housed in a PowerFLAT™ 3.3×3.3 HV package with exposed drain thermal pad (pins 5–8), single gate terminal (pin 4), and source terminals (pins 1–3). The bottom-exposed drain improves thermal transfer to PCB copper.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3 (S)	Source	Low-side return path; paralleled for reduced bond-wire inductance and resistance
4 (G)	Gate	Control input requiring ≤25 nC charge; sensitive to ringing due to low Crss
5, 6, 7, 8 (D)	Drain	High-side power node and primary thermal path to PCB via exposed copper pad

Key Features

Feature	Design Value
Ultra-low R_DS(on)	4.6 mΩ typ. enables >95% efficiency in 12–48 V buck converters at 20 A
Low Crss/Ciss ratio	0.041 minimizes dv/dt-induced gate disturbance during high-side switching
High avalanche ruggedness	Rated for unclamped inductive switching - supports robust operation in motor drives
Optimized for PCB thermal dissipation	R_thj-pcb = 42.8 °C/W on 1 in² 2 oz Cu - eliminates need for external heatsink

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF7470PBF	R_DS(on) = 5.2 mΩ @ 10 V; C_iss = 1520 pF; Crss = 85 pF; PowerSO-8 package	Higher thermal resistance (R_thj-pcb ≈ 60 °C/W); less EMI-robust Crss/Ciss ratio (0.056)	Prefer when legacy SO-8 footprint compatibility is required over PCB thermal performance.
DMTH6005LPSQ	R_DS(on) = 4.5 mΩ @ 10 V; Q_g = 27.5 nC; Crss = 75 pF; PowerFLAT 5×6 package	Larger footprint; higher gate charge increases driver loss at high frequency	Choose when higher current derating (ID = 30 A @ T_pcb = 25 °C) justifies larger board area.

Compared with IRF7470PBF and DMTH6005LPSQ, STL20N6F7 offers the lowest Crss/Ciss ratio (0.041) and best PCB-level thermal resistance (42.8 °C/W), making it optimal for space-constrained, high-frequency, high-efficiency 48 V systems.

FAQ

What is the maximum continuous drain current for STL20N6F7 at PCB temperature of 100 °C?

The maximum continuous drain current is 12 A when mounted on a standard FR-4 PCB at T_pcb = 100 °C, based on R_thj-pcb = 42.8 °C/W and T_j(max) = 150 °C. This reflects real-world thermal limits under sustained load without heatsink.

Does STL20N6F7 have avalanche capability, and is it rated?

Yes - STL20N6F7 is specified for unclamped inductive switching (UIS) per JEDEC JESD24-1. Its avalanche ruggedness is validated in the datasheet's safe operating area (SOA) curves and used in motor drive designs where inductive energy must be absorbed safely.

Can STL20N6F7 be used in synchronous rectification with body diode conduction?

Yes - its source-drain diode has characterized trr = 39.6 ns and Q_rr = 36 nC at ID = 20 A, di/dt = 100 A/µs. These values support use in synchronous rectifier topologies where controlled body diode conduction precedes active switching.

What is the recommended PCB footprint for thermal reliability?

The manufacturer specifies a dedicated PowerFLAT™ 3.3×3.3 HV footprint (Figure 20), including 3.15 mm × 3.15 mm thermal pad with 0.65 mm solder mask opening and 0.3 mm stencil aperture for optimal thermal transfer and solder joint integrity.
