Product details

Overview

STP140N6F7 from STMicroelectronics is an N-channel enhancement-mode Power MOSFET using STripFET™ F7 trench technology, designed for high-efficiency switching in power conversion stages. It delivers 60 V V_DS, 0.0031 Ω typ. R_DS(on) at V_GS = 10 V and I_D = 40 A, 80 A continuous drain current, 158 W total power dissipation, and 160 mJ single-pulse avalanche energy - deployed in DC-DC converters, motor drives, and industrial SMPS.

For engineers reviewing the STP140N6F7 datasheet, STP140N6F7 pinout, STP140N6F7 application, or STP140N6F7 equivalent, key selection criteria include its low Crss/Ciss ratio for EMI immunity, high junction temperature rating (175 °C), TO-220 package thermal resistance (0.95 °C/W), and verified unclamped inductive switching ruggedness.

Technical Context

This MOSFET employs an enhanced trench gate structure that reduces both R_DS(on) and gate charge (Q_g = 55 nC typ.), enabling fast switching with minimal conduction and switching losses. Its low Crss (193 pF) relative to Ciss (3100 pF) improves noise immunity during high-dV/dt transitions.

The device operates with a gate threshold voltage of 2–4 V, supports ±20 V gate drive, and maintains stable on-resistance up to 125 °C case temperature. Its source-drain diode exhibits 1.2 V forward voltage at 80 A and 42.4 ns reverse recovery time under defined inductive load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage for 48 V bus-level applications
R_DS(on) typ.	0.0031 Ω at V_GS = 10 V, I_D = 40 A - enables <100 mW conduction loss at 80 A
I_D cont.	80 A at T_case = 25 °C - limited by TO-220 package thermal capacity
E_AS	160 mJ - supports robust unclamped inductive switching without failure
C_rss/C_iss	193/3100 pF - low ratio minimizes Miller-induced turn-on risk in hard-switched topologies
Q_g	55 nC - reduces gate driver power requirement and switching transition time
R_thj-case	0.95 °C/W - allows 158 W dissipation with ≤150 °C junction-to-case delta

Pinout & Package

STP140N6F7 is housed in a standard TO-220 type A package with isolated tab (drain-connected). The package features a metal tab for heatsinking, 3 leads, and RoHS-compliant ECOPACK® construction.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heatsink interface	Electrically connected to metal tab; requires insulating washer if mounted to grounded heatsink
Source	Reference node for gate drive and current return	Low-inductance connection critical for minimizing shoot-through risk in half-bridge configurations
Gate	Control terminal for channel modulation	High-impedance input requiring <55 nC charge for full enhancement; sensitive to ESD

Key Features

Feature	Design Value
Ultra-low R_DS(on)	0.0031 Ω typ. enables >98% efficiency in 48 V/80 A synchronous rectifier stages
Low Crss/Ciss ratio	6.2% ratio suppresses false turn-on during high-speed switching in noisy environments
High avalanche ruggedness	160 mJ E_AS rating validated per JEDEC JESD24-11, supporting reliable operation without snubbers
Enhanced thermal performance	0.95 °C/W R_thj-case allows sustained 80 A operation with forced-air cooling at 25 °C ambient

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 60 V power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFB4115PBF	R_DS(on) = 0.0032 Ω, Q_g = 120 nC, TO-220AB package	Higher gate charge increases driver loss and slows switching; lower Crss/Ciss ratio (5.8%) but less E_AS (120 mJ)	Preferable only where gate drive strength exceeds 2 A and avalanche stress is minimal
IXTH80N60L2	R_DS(on) = 0.0042 Ω, Q_g = 48 nC, TO-247 package	Higher R_DS(on) raises conduction loss; TO-247 offers better thermal margin but larger footprint	Suitable when board layout allows larger package and junction temperature must stay below 150 °C under 100% load

Compared with IRFB4115PBF and IXTH80N60L2, STP140N6F7 provides the lowest R_DS(on) × Q_g figure of merit (0.171 Ω·nC), optimal for high-frequency, high-current switching where both efficiency and EMI control are critical.

FAQ

What is the maximum safe operating temperature for STP140N6F7?

The absolute maximum junction temperature is 175 °C, and the storage temperature range is –55 to +175 °C. Operation above 150 °C junction temperature requires derating per the Safe Operating Area (SOA) curves in Figure 2 of the datasheet, with thermal design ensuring R_thj-case ≤ 0.95 °C/W under actual airflow and heatsink conditions.

Is STP140N6F7 suitable for paralleling multiple devices?

Yes - its positive temperature coefficient of R_DS(on) (see Figure 10) ensures inherent current sharing when paralleled. Successful implementation requires matched gate drive impedance, symmetrical PCB layout, and identical heatsinking to maintain ΔT_j < 5 °C between units for stable load distribution at 80 A total.

Does STP140N6F7 have built-in ESD protection?

No - it lacks integrated gate protection diodes. The gate oxide is rated for ±20 V V_GS, and IGSS is specified at 100 nA at V_GS = +20 V. External Zener clamps (e.g., 15 V) and series gate resistors are required in production designs to prevent ESD damage during handling and PCB assembly.

Can STP140N6F7 replace older STripFET™ F4 or F5 devices?

Yes - it is a direct upgrade with lower R_DS(on) (–22% vs. STP160N6F5), reduced Q_g (–18%), and improved E_AS (+20%). Pinout and package are identical, allowing drop-in replacement; however, gate drive timing may require minor adjustment due to faster switching transitions and lower Crss.
