Product details
Overview
STS5PF30L from STMicroelectronics is a P-channel enhancement-mode Power MOSFET in SO-8 package, rated for 30V VDS, 5A continuous drain current at TC = 25°C, and 0.045Ω RDS(on) at VGS = 10V. It delivers low conduction and switching losses with ±16V gate drive capability, and is used in DC-DC converter high-side switches and load switching circuits requiring fast turn-off and rugged avalanche performance.
For engineers reviewing the STS5PF30L datasheet, STS5PF30L pinout, STS5PF30L application, or STS5PF30L equivalent, key selection considerations include its p-channel polarity, 4.5V logic-level gate threshold (VGS(th) = 1–2.5V), 12.5–16nC total gate charge, integrated source-drain diode with 1.2V forward drop, and SO-8 thermal resistance of 50°C/W on FR-4 board.
Technical Context
This device uses ST's "single feature size™" strip-based STripFET™ process to achieve high cell density and low RDS(on) while maintaining robust avalanche energy rating and manufacturing reproducibility. Its p-channel configuration enables high-side switching without level-shifting circuitry, and the 1.2V source-drain diode forward voltage supports synchronous rectification in buck converters.
The MOSFET exhibits 1350pF input capacitance (Ciss) and 130pF reverse transfer capacitance (Crss) at VDS = 25V, enabling predictable switching behavior with 4.7Ω gate resistor. Turn-off delay (125ns) dominates over turn-on delay (25ns), making it suitable for applications where controlled turn-off timing is critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar p-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF7416PbF | RDS(on) = 0.042Ω @ VGS=10V; higher Ciss (1600pF); same SO-8 package | Slightly faster turn-on but slower turn-off (140ns td(off)); less optimized for 4.5V drive | Prefer when lower RDS(on) is critical and gate drive strength permits higher Ciss loading |
| DMG2305UVT | RDS(on) = 0.052Ω @ VGS=4.5V; smaller TSOP-6 package; lower power dissipation (1.4W) | Limited to 3.5A continuous; unsuitable for 5A sustained loads or high-temperature environments | Select only for space-constrained 3.3V logic-driven loads under 3A with derated thermal margin |
Compared with IRF7416PbF and DMG2305UVT, STS5PF30L offers balanced trade-offs: superior 4.5V drive capability (VGS(th) down to 1V), rugged SO-8 thermal footprint, and guaranteed 5A continuous rating at 100°C case temperature-making it optimal for industrial-grade high-side switching where reliability and thermal headroom are prioritized.

FAQ
Is STS5PF30L suitable for 3.3V microcontroller gate drive?
Yes. With a gate threshold voltage (VGS(th)) ranging from 1.0V to 2.5V, STS5PF30L fully turns on using 3.3V logic-level signals. At VGS = 4.5V, it achieves RDS(on) ≤ 0.065Ω, ensuring low conduction loss without requiring external level-shifting circuitry.
What is the maximum pulsed drain current rating?
The absolute maximum pulsed drain current (IDM) is 20A, limited by safe operating area (SOA) constraints. This rating applies under pulse conditions with duty cycle ≤1.5% and pulse width ≤300µs, as defined in the datasheet's Electrical Ratings table.
Does STS5PF30L include an integrated body diode?
Yes. It features an inherent source-drain body diode with forward voltage (VSD) of 1.2V at ISD = 5A and VGS = 0V. This diode supports freewheeling in inductive load switching and synchronous rectification, with reverse recovery time (trr) of 45ns at Tj = 150°C.
Can STS5PF30L be used in automotive applications?
STS5PF30L is not qualified as AEC-Q101 automotive grade. While its −55°C to +150°C junction temperature range meets some under-hood thermal requirements, ST explicitly states in the datasheet that non-automotive-grade parts are intended for industrial use only and carry no automotive qualification or warranty.
