Product details

Overview

STP160N3LL from STMicroelectronics is an N-channel 30 V, 120 A Power MOSFET in TO-220 package, featuring 2.5 mΩ typ. R_DS(on) at V_GS = 10 V, 42 nC total gate charge, and 136 W power dissipation-designed for high-efficiency DC-DC converters and motor control switches in industrial power supplies.

For engineers reviewing the STP160N3LL datasheet, STP160N3LL pinout, STP160N3LL application, or STP160N3LL equivalent, key selection criteria include its low R_DS(on), high pulsed current capability (480 A), avalanche ruggedness (150 mJ), thermal resistance (1.1 °C/W), and TO-220 mechanical compatibility with standard heatsinks.

Technical Context

This device uses STripFET™ H6 trench-gate technology to achieve ultra-low on-resistance and reduced gate charge. Its 30 V V_DS rating and ±20 V V_GS support robust gate drive in 24 V systems, while the 1.1 °C/W R_th(j-case) enables high continuous current operation up to 112 A at 100 °C case temperature.

The integrated source-drain diode delivers 1.1 V forward voltage at 60 A and fast recovery (t_rr = 28.6 ns, Q_rr = 22.8 nC), making it suitable for synchronous rectification and hard-switched topologies where body diode performance impacts efficiency.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - supports 24 V nominal bus systems with margin for transients
R_DS(on) max	3.2 mΩ at V_GS = 10 V - limits conduction loss to ≤4.6 W at 120 A
I_D cont.	120 A at T_case = 25 °C - package-limited current for high-power switching
E_AS	150 mJ - withstands unclamped inductive switching events without failure
Q_g	42 nC - enables efficient 100 kHz+ switching with moderate gate driver strength
R_th(j-case)	1.1 °C/W - allows 123 °C junction rise at full 136 W dissipation with 25 °C heatsink
t_rr	28.6 ns - minimizes reverse recovery loss in bridge-leg configurations

Pinout & Package

TO-220 type A package with isolated tab (drain-connected), standard 3-pin vertical mounting configuration. Mounting hole Ø3.75–3.85 mm, lead pitch 2.54 mm, heatsink interface area 15.5 × 10.2 mm.

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main current path output / heatsink connection	Electrically connected to metal tab; requires insulating washer when mounted to grounded heatsink
Source	Reference node for gate drive and current sensing	Low-inductance return path; used for shunt-based current monitoring in half-bridge legs
Gate	Control terminal for channel modulation	High-impedance input requiring <42 nC charge for full enhancement; sensitive to ESD

Key Features

Feature	Design Value
Ultra-low R_DS(on)	2.5 mΩ typ. at 10 V gate drive reduces I²R losses by >30% vs. legacy TO-220 MOSFETs in 12–24 V systems
Low gate charge	42 nC total charge enables <1 W gate drive loss at 200 kHz with 12 V supply and 5 Ω driver
High avalanche energy rating	150 mJ single-pulse rating supports reliable operation in inductive load switching without external snubbers
Fast body diode recovery	28.6 ns t_rr and 22.8 nC Q_rr reduce cross-conduction loss in synchronous buck and half-bridge topologies

Applications

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
IRF1404PBF	R_DS(on) = 4.0 mΩ max (higher conduction loss); Q_g = 131 nC (slower switching)	Lower switching frequency suitability (≤50 kHz); less efficient at high current	Prefer when gate drive strength is limited and thermal margin exists
IXTH120N30L2	V_DS = 300 V (over-rated); R_DS(on) = 3.8 mΩ; TO-247 package (larger footprint)	Designed for higher-voltage systems; not optimized for 24 V conduction efficiency	Choose only if system requires 300 V rating or TO-247 mechanical fit

Compared with IRF1404PBF and IXTH120N30L2, STP160N3LL delivers superior conduction efficiency at 24 V, lower gate drive demand, and TO-220 thermal performance optimized for industrial power density-making it the preferred choice for cost-sensitive, high-current 30 V switching applications.

FAQ

Is STP160N3LL suitable for synchronous rectification?

Yes. Its integrated source-drain diode has 1.1 V forward voltage at 60 A and 28.6 ns reverse recovery time, enabling efficient synchronous rectification in buck converters up to 200 kHz. Gate threshold of 1–2.5 V allows direct control by standard logic-level drivers without level-shifting.

What is the maximum safe operating area (SOA) at 100 °C case temperature?

At T_case = 100 °C, the SOA limits continuous drain current to 112 A (per datasheet Table 2). For pulse operation, the device supports 480 A pulses with duty cycle and pulse width constrained by the SOA curve in Figure 2-ensuring safe operation under transient overload conditions.

Does STP160N3LL require a gate resistor for stability?

A gate resistor (typically 2.2–10 Ω) is recommended to dampen ringing caused by PCB trace inductance and intrinsic gate resistance (1 Ω). Without it, overshoot exceeding ±20 V V_GS may trigger parasitic turn-on or damage the gate oxide during fast switching transitions.

Can STP160N3LL be paralleled for higher current capacity?

Yes-its positive temperature coefficient of R_DS(on) (see Figure 10) ensures inherent current sharing. Parallel operation requires matched gate drive paths, symmetrical layout, and individual gate resistors to prevent oscillation. Derate total current by 15% for thermal coupling effects in shared heatsink configurations.
