STMicroelectronics STP60NF03L

Overview

STP60NF03L from STMicroelectronics is an N-channel enhancement-mode Power MOSFET in TO-220 package, rated for 30V V_DSS, 60A continuous drain current at T_C = 25°C, and 8 mΩ R_DS(on) at V_GS = 10 V. It features rugged avalanche capability (650 mJ E_AS) and low gate charge (43 nC), enabling high-efficiency switching in DC-DC converters and motor drive half-bridges.

For engineers reviewing the STP60NF03L datasheet, STP60NF03L pinout, STP60NF03L application, or STP60NF03L equivalent, key selection criteria include its 30V rating, 8 mΩ on-resistance at 10 V gate drive, TO-220 thermal resistance (1.5 °C/W junction-to-case), avalanche energy rating, and gate threshold voltage range (1.0–2.5 V).

Technical Context

This MOSFET employs ST's STripFET™ II process with single-feature-size strip geometry, delivering high cell density and low R_DS(on). Its gate threshold voltage (1.0–2.5 V) supports direct logic-level drive from 3.3 V and 5 V microcontrollers without level-shifting.

The device integrates a fast-recovery body diode (t_rr = 75 ns, Q_rr = 100 µC) and exhibits stable safe operating area up to 240 A pulsed drain current, making it suitable for hard-switched inductive loads such as solenoid drivers and brushed DC motor H-bridges.

Key Specifications

Pinout & Package

TO-220 package with standard three-terminal layout: Drain (tab), Source (pin 1), Gate (pin 2). Mounting tab is electrically connected to Drain. Thermal pad requires insulated mounting or isolation washer when heatsink is grounded.

FAQ

Is STP60NF03L suitable for 3.3 V microcontroller gate drive?

Yes. With a gate threshold voltage range of 1.0–2.5 V and guaranteed turn-on at V_GS = 4.5 V (R_DS(on) ≤ 9.5 mΩ), it interfaces directly with 3.3 V logic outputs. However, full 60 A performance requires ≥10 V gate drive to achieve 8 mΩ R_DS(on).

What is the maximum continuous current at 100°C case temperature?

The datasheet specifies 42 A continuous drain current at T_C = 100°C. This derating reflects thermal limits-not electrical degradation-and assumes proper heatsinking with R_thj-case ≤ 1.5 °C/W maintained.

Does STP60NF03L have a lead-free package?

Yes. It is supplied in an ECOPACK®-compliant TO-220 package with lead-free second-level interconnect, meeting JEDEC JESD97 standards. The inner box label indicates the lead-free status and soldering profile compliance.

Can STP60NF03L replace IRF3205 in existing designs?

No. While both are TO-220 N-channel MOSFETs, IRF3205 has 55 V V_DSS and 8 mΩ R_DS(on), but STP60NF03L is limited to 30 V. Substituting it into a 48 V system risks avalanche breakdown. Use only in ≤24 V nominal applications.
