Product details

Overview

STF100N6F7 from STMicroelectronics is an N-channel 60 V, 4.6 mΩ typ. R_DS(on), 46 A continuous drain current Power MOSFET in TO-220FP package, optimized for high-efficiency switching in DC-DC converters and motor control stages where low conduction loss and fast switching are critical.

For engineers reviewing the STF100N6F7 datasheet, STF100N6F7 pinout, STF100N6F7 application, or STF100N6F7 equivalent, key selection criteria include its 6 °C/W junction-to-case thermal resistance, 30 nC total gate charge, 86 pF Crss/Ciss ratio for EMI immunity, and 200 mJ single-pulse avalanche energy rating.

Technical Context

This device employs STripFET™ F7 trench-gate technology to achieve ultra-low R_DS(on) while reducing internal capacitances (C_iss = 1980 pF, C_oss = 970 pF) and gate charge (Q_g = 30 nC), enabling high-frequency operation with reduced switching losses.

Its robust safe operating area supports pulsed drain currents up to 184 A, and the integrated source-drain diode delivers 48.4 ns reverse recovery time (t_rr) and 47 nC Q_rr at 46 A, making it suitable for synchronous rectification and inductive load switching.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage for 48 V bus-level power conversion
R_DS(on) typ.	4.6 mΩ at V_GS = 10 V, ID = 23 A - enables <1.05 W conduction loss at 46 A
I_D cont. @ T_C = 25 °C	46 A - continuous current capability with heatsink mounting
Q_g	30 nC - determines gate drive power and switching speed in hard-switched topologies
E_AS	200 mJ - unclamped inductive energy handling without failure at T_J = 25 °C
R_thj-case	6 °C/W - defines minimum heatsink requirement for thermal management
t_rr	48.4 ns - fast body diode recovery reduces cross-conduction loss in half-bridge configurations

Pinout & Package

The STF100N6F7 is housed in a TO-220FP (Full-Pak) package with insulated tab, enabling direct mounting to heatsinks without electrical isolation hardware. The plastic body provides creepage/clearance compliance per IEC 60950-1.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path collector	Electrically connected to metal tab; requires insulating washer if mounted to grounded heatsink
Source	Reference node for gate drive and current sensing	Low-inductance connection point for shunt resistor placement and gate return path
Gate	Control terminal for channel modulation	High-impedance input requiring <20 V max. drive; sensitive to ESD and ringing

Key Features

Feature	Design Value
Ultra-low R_DS(on)	4.6 mΩ typ. minimizes I²R losses in high-current 12–48 V systems
Low Crss/Ciss ratio	86/1980 ≈ 0.043 - suppresses Miller-induced false turn-on during high dV/dt transitions
High avalanche ruggedness	200 mJ single-pulse rating - withstands inductive kickback without derating in relay/motor drivers
Enhanced thermal performance	6 °C/W R_thj-case - allows 25 W dissipation with ≤150 °C junction rise over 25 °C case

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
IRFZ44NPBF	R_DS(on) = 28 mΩ @ 10 V; Q_g = 67 nC; TO-220 package (non-isolated tab)	Higher conduction loss limits use to ≤15 A continuous; no avalanche rating specified	Select only for cost-sensitive, low-frequency (<50 kHz), low-current designs where thermal margin is ample
IXTP100N065T	R_DS(on) = 5.2 mΩ @ 10 V; Q_g = 42 nC; TO-220 package with isolated tab	Slightly higher gate charge increases drive loss; same voltage rating but lower E_AS (120 mJ)	Prefer when needing tighter R_DS(on) tolerance (±10%) and extended temperature range (−65 to 175 °C)

Compared with IRFZ44NPBF and IXTP100N065T, the STF100N6F7 offers the lowest R_DS(on) and highest avalanche energy, making it optimal for high-reliability, high-frequency, high-current switching where thermal and transient robustness are prioritized over gate drive simplicity.

FAQ

What is the maximum gate-source voltage rating for STF100N6F7?

The absolute maximum V_GS is ±20 V, as specified in Table 2 of the datasheet. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 10–15 V for full enhancement, with transient spikes clamped below 18 V using Zener diodes or active gate drivers.

Can STF100N6F7 be used in avalanche mode repeatedly?

No - the 200 mJ E_AS rating applies only to single-pulse unclamped inductive switching events. Repeated avalanche operation causes cumulative junction degradation and is not guaranteed by ST. Designers must ensure SOA compliance and avoid sustained avalanche conditions through proper snubbing or clamping.

Is the TO-220FP package electrically insulated?

Yes - the TO-220FP package features an insulated metal tab rated for 2500 V_RMS insulation withstand voltage between all three leads and external heatsink (1 s, 25 °C). This eliminates need for mica washers or silicone pads in most industrial mounting configurations.

How does the Crss/Ciss ratio impact EMI performance?

A low Crss/Ciss ratio (86/1980 ≈ 0.043) reduces Miller feedback during high dV/dt transitions, minimizing gate voltage overshoot and false turn-on. This directly lowers radiated emissions in switching nodes and improves system-level EMC compliance without additional filtering components.
