STMicroelectronics STS4C3F60L

Overview

STS4C3F60L from STMicroelectronics is an N-channel 60 V, 4 A complementary-pair Power MOSFET in SO-8 package, featuring R_DS(on) ≤ 0.055 Ω at V_GS = 10 V, 2 A, rugged avalanche capability, and low-threshold gate drive (V_GS(th) = 1–1.5 V). It serves as a high-density switching element in DC-DC converters and motor control half-bridges.

For engineers reviewing the STS4C3F60L datasheet, STS4C3F60L pinout, STS4C3F60L application, or STS4C3F60L equivalent, key selection criteria include its 60 V V_DS, 0.045 Ω typical R_DS(on), 15 ns turn-on delay, 4 A continuous drain current at T_C = 25°C, and SO-8 thermal performance with R_thj-a = 62.5 °C/W on 1 in² 2 oz copper.

Technical Context

This dual-channel complementary MOSFET pair integrates matched N- and P-channel devices fabricated using ST's Single Feature Size™ strip-based process, enabling high cell density and reproducible low on-resistance. The N-channel device delivers 7 S forward transconductance and 1030 pF input capacitance at V_DS = 25 V, f = 1 MHz.

It supports fast switching with 15 ns turn-on delay and 45 ns turn-off delay under 4.7 Ω gate resistance, and exhibits robust unclamped inductive switching behavior with 85 ns reverse recovery time and 85 nC Q_rr at T_j = 150°C - critical for synchronous rectification and H-bridge motor drives.

Key Specifications

Pinout & Package

STS4C3F60L uses the standard SO-8 surface-mount package (JEDEC MS-012), with exposed drain pad for enhanced thermal transfer. Pin numbering follows conventional SO-8 orientation (pin 1 marked).

FAQ

Is STS4C3F60L a single MOSFET or a dual device?

STS4C3F60L is a monolithic complementary pair: one N-channel and one P-channel MOSFET integrated into a single SO-8 package with shared thermal pad. It is not two independent dice - the devices are electrically isolated but thermally coupled, enabling matched thermal response in half-bridge configurations.

What is the maximum safe operating temperature for continuous operation?

The absolute maximum junction temperature is 150°C, and the device supports continuous 4 A drain current only at case temperature ≤25°C. At T_C = 100°C, rated current drops to 2.5 A (N-channel) - sustained operation above 135°C risks irreversible parametric shift per ST's reliability data.

Can STS4C3F60L be used in linear (analog) mode for current regulation?

Yes - the N-channel device supports linear-mode operation with guaranteed safe operating area (SOA) curves up to 100 V × 0.5 A (DC) and 60 V × 2 A (10 ms pulse). Its 1.2 V source-drain diode forward voltage and 7 S transconductance enable stable analog current sink behavior when biased with precision gate voltage.

Does the SO-8 package require special PCB layout considerations?

Yes - pins 7 and 8 are internally shorted to the exposed drain thermal pad. This pad must be soldered to a minimum 1 in² copper area (2 oz) for specified R_thj-a = 62.5 °C/W. Thermal vias under the pad (≥6 × 0.3 mm) are recommended to improve heat transfer to inner layers.
