STMicroelectronics STV160NF03LT4

Overview

STV160NF03LT4 from STMicroelectronics is an N-channel 30 V, 160 A PowerSO-10 packaged STripFET™ II MOSFET with R_DS(on) = 1.9 mΩ at V_GS = 10 V and T_j = 25°C, ultra-low gate charge (Q_g = 103 nC), and 100% avalanche tested - designed for synchronous rectification in high-current VRM/DC-DC buck converters.

For engineers reviewing the STV160NF03LT4 datasheet, STV160NF03LT4 pinout, STV160NF03LT4 application, or STV160NF03LT4 equivalent, key selection criteria include its 0.71 °C/W junction-to-case thermal resistance, 160 A continuous drain current at T_C = 25°C, low-profile PowerSO-10 package with 4 nH source inductance, and fast switching (t_r = 380 ns, t_f = 170 ns) for high-efficiency power stages.

Technical Context

This MOSFET employs ST's second-generation STripFET™ II process with a strip layout architecture to achieve ultra-high cell density and minimized R_DS(on). Its gate threshold voltage (V_GS(th)) is 1 V (min), enabling compatibility with 3.3 V and 5 V logic-level drive.

The device features integrated source-drain diode with V_SD = 1.5 V at I_SD = 160 A and fast reverse recovery (t_rr = 80 ns, Q_rr = 180 nC), supporting hard-switched and synchronous rectifier topologies without external Schottky replacement in many cases.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous drain current for STV160NF03LT4 at 100°C case temperature?

The maximum continuous drain current is 113 A when the case temperature (T_C) is maintained at 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerSO-10 package and must be validated with actual PCB copper area and airflow conditions.

Does STV160NF03LT4 require a gate resistor for stable operation in a 500 kHz buck converter?

Yes - a gate resistor (typically 2.2–4.7 Ω) is recommended to dampen ringing caused by gate loop inductance and prevent spurious turn-on due to dV/dt coupling. The device's low input capacitance (C_iss = 4700 pF) and 0.5 Ω intrinsic gate resistance make external control essential for clean switching at high frequencies.

Can STV160NF03LT4 replace STB160NF03L in existing designs?

No - STB160NF03L uses a TO-220 package with different thermal and mechanical characteristics. While electrically similar, the PowerSO-10 footprint, soldering profile, thermal interface, and pinout are incompatible. Board redesign and thermal validation are required for substitution.

Is the body diode of STV160NF03LT4 suitable for asynchronous operation in a buck converter?

Yes - the body diode is fully characterized with V_SD = 1.5 V at 160 A and t_rr = 80 ns, enabling reliable asynchronous operation up to ~200 kHz. However, synchronous rectification is strongly preferred above 100 kHz to avoid excessive conduction loss and reverse recovery stress.
