Product details

Overview

STP60NH2LL from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TO-220 package, rated for 24 V V_DSS, 40 A continuous drain current at T_C = 25°C, and 0.010 Ω R_DS(on) at V_GS = 10 V. It features low gate charge (Q_g = 27 nC), fast switching (t_f = 10 ns), and optimized for high-efficiency synchronous buck converters.

For engineers reviewing the STP60NH2LL datasheet, STP60NH2LL pinout, STP60NH2LL application, or STP60NH2LL equivalent, key selection criteria include conduction loss minimization in low-side switch positions, avalanche energy rating (E_AS = 600 mJ), thermal resistance (R_thj-case = 2.5 °C/W), and compatibility with 4.5 V logic-level gate drive.

Technical Context

This MOSFET employs ST's STripFET™ II process to achieve industry-leading R_DS(on) × Q_g product, enabling reduced conduction and switching losses simultaneously. Its low threshold voltage (V_GS(th) = 1 V typ.) supports direct 3.3 V/5 V microcontroller drive without level-shifting.

The device is specifically engineered as a low-side switch in DC-DC converters, where its low C_oss (385 pF) and Q_rr (28 µC) minimize reverse recovery losses in the high-side FET during commutation, and its robust SOA supports unclamped inductive switching up to 600 mJ.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	24 V - Maximum blocking voltage in low-side configuration; compatible with 12 V–24 V input rails
R_DS(on)	0.010 Ω @ V_GS = 10 V - Enables ≤4 W conduction loss at 20 A, critical for thermal management
I_D (cont)	40 A @ T_C = 25°C - Supports high-current power stages without parallel devices
Q_g	27 nC - Reduces gate driver power demand and enables <100 ns total switching transitions
E_AS	600 mJ - Withstands single-pulse inductive energy in unclamped load conditions without failure
R_thj-case	2.5 °C/W - Allows direct heatsink mounting for >40 W dissipation at ΔT = 100°C
V_GS(th)	1 V typ. - Ensures full enhancement with 3.3 V logic, eliminating need for gate boosters

Pinout & Package

TO-220 package with standard three-terminal configuration: Drain (tab), Source (pin 1), Gate (pin 2). Mounting tab is electrically connected to Drain. Pin 3 is not used (NC).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path collector	Electrically tied to metal tab; requires insulating washer when mounted to grounded heatsink
Source (Pin 1)	Reference node for gate drive and current sensing	Low-inductance return path; critical for stable gate control in high-dI/dt applications
Gate (Pin 2)	Control electrode	High-impedance input requiring <4.7 Ω series resistor to damp ringing and limit peak current

Key Features

Feature	Design Value
STripFET™ II process integration	Enables 0.010 Ω R_DS(on) in TO-220 without die size penalty, reducing cost per ampere
Low Q_rr (28 µC)	Minimizes cross-conduction risk and switching loss in synchronous rectification topologies
Robust avalanche rating	600 mJ single-pulse E_AS allows reliable operation under transient overcurrent without external snubbers
ECOPACK® lead-free construction	Meets RoHS Directive 2011/65/EU and JEDEC JESD97 marking requirements for industrial assembly

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-side power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFZ44NPBF	R_DS(on) = 0.028 Ω @ 10 V; Q_g = 67 nC; E_AS = 120 mJ	Higher conduction loss, lower avalanche ruggedness, slower switching	Acceptable for lower-frequency (<50 kHz), lower-current (<15 A) designs where cost is primary
STP55NF06L	V_DSS = 60 V; R_DS(on) = 0.014 Ω @ 10 V; Q_g = 45 nC	Higher voltage rating trades off R_DS(on) and Q_g; less optimal for 24 V systems	Preferred only if system requires 48 V input compatibility or higher fault margin

Compared with IRFZ44NPBF and STP55NF06L, STP60NH2LL delivers superior efficiency in 24 V synchronous buck converters due to its lower R_DS(on) × Q_g product and higher E_AS, directly translating to cooler operation and smaller heatsinks.

FAQ

Is STP60NH2LL suitable for 3.3 V microcontroller gate drive?

Yes. With a typical gate threshold voltage of 1 V and guaranteed turn-on at V_GS ≥ 2.5 V, STP60NH2LL fully enhances using standard 3.3 V GPIO outputs. No level shifter is required, though a 10 Ω series gate resistor is recommended to control dV/dt and prevent oscillation.

What is the maximum safe operating temperature for continuous 40 A operation?

Continuous 40 A operation is rated only at T_C = 25°C. At T_C = 100°C, the absolute maximum continuous drain current drops to 28 A per the datasheet's derating curve. For sustained 40 A loads, junction temperature must be maintained below 125°C using a heatsink with ≤2.5 °C/W thermal resistance.

Does STP60NH2LL have integrated body diode recovery optimization?

Yes. The device features a fast, soft-recovery body diode with t_rr = 32.5 ns and Q_rr = 28 µC at T_j = 150°C. This is explicitly optimized for synchronous rectification, minimizing voltage spikes and cross-conduction losses during high-side FET turn-on in buck converters.

Can STP60NH2LL replace STP60NF06 in a 24 V system?

No. STP60NF06 has V_DSS = 60 V and R_DS(on) = 0.014 Ω, making it over-specified and less efficient for 24 V applications. STP60NH2LL's 24 V rating, lower R_DS(on), and lower Q_g deliver better performance and thermal behavior in 24 V systems, but it is not a drop-in replacement due to different voltage class and pin-compatible layout constraints.
