STMicroelectronics STS7PF30L

Overview

STS7PF30L from STMicroelectronics is a P-channel enhancement-mode power MOSFET in SO-8 package, rated for 30 V V_DSS, 7 A continuous drain current at T_C = 25°C, and typ. R_DS(on) = 0.016 Ω at V_GS = 10 V. It features low-threshold gate drive (V_GS(th) = 1.0–2.5 V), integrated source-drain diode with 1.2 V forward voltage at 7 A, and rugged unclamped inductive switching capability - used in battery protection circuits of portable phones and nomadic equipment.

For engineers reviewing the STS7PF30L datasheet, STS7PF30L pinout, STS7PF30L application, or STS7PF30L equivalent, key selection criteria include verified P-channel logic-level gate compatibility, SO-8 thermal performance on FR4 (R_thj-amb = 50 °C/W), source-drain diode recovery (t_rr = 40 ns), and safe operating area under pulsed 28 A conditions.

Technical Context

This MOSFET employs ST's StripFET™ II process with single-feature-size geometry, enabling high cell density and low R_DS(on) without compromising avalanche ruggedness. Its P-channel topology allows high-side load switching with simple gate control referenced to ground, eliminating need for level-shifting circuitry in battery disconnect paths.

The device integrates a fast-recovery body diode (t_rr = 40 ns, Q_rr = 46 nC) optimized for synchronous rectification and reverse-polarity protection. Gate charge parameters (Q_g = 28 nC, Q_gd = 12 nC) support efficient 4.5 V logic-level driving in portable DC/DC and power-path management.

FAQ

What is the maximum safe operating temperature for STS7PF30L during continuous operation?

The junction temperature must not exceed 150 °C. At T_C = 100 °C, the device supports 4.4 A continuous drain current. With R_thj-amb = 50 °C/W on standard FR4, ambient temperature must be kept below 85 °C for full 7 A operation - verified via unclamped inductive testing per Figure 2.

Can STS7PF30L be driven directly by a 3.3 V microcontroller GPIO without external components?

Yes. With V_GS(th) max = 2.5 V and guaranteed turn-on at V_GS = 3.3 V, the MOSFET achieves full enhancement and low R_DS(on) without gate drivers or level shifters. Measured R_DS(on) = 0.022 Ω at V_GS = 3.3 V and I_D = 3.5 A confirms robust logic-level compatibility.

Does STS7PF30L include an integrated body diode, and what are its recovery characteristics?

Yes - it features a monolithic source-drain diode with forward voltage V_SD = 1.2 V at 7 A and reverse recovery time t_rr = 40 ns at T_j = 150 °C, di/dt = 100 A/µs. Q_rr = 46 nC and I_RRM = 2.3 A are measured per Figure 5 test circuit, supporting fast-switching power-path arbitration.

Is the SO-8 package of STS7PF30L compatible with standard automated pick-and-place equipment?

Yes. The device uses JEDEC-standard SO-8 outline (MS-012AC) with 1.27 mm pitch and defined land pattern per datasheet page 5. Lead coplanarity ≤ 0.10 mm and gull-wing lead form ensure reliable placement and reflow soldering on Type II and III assembly lines.
