Product details

Overview

STT2PF60L from STMicroelectronics is a P-channel enhancement-mode Power MOSFET in SOT-23-6L package, rated for 60 V V_DS, 2 A continuous drain current at 25°C, and 0.20 Ω typical R_DS(on) at V_GS = 10 V. It features rugged avalanche capability, low gate charge (5 nC), and is optimized for high-density DC-DC converters and battery management in portable electronics.

For engineers reviewing the STT2PF60L datasheet, STT2PF60L pinout, STT2PF60L application, or STT2PF60L equivalent, key selection criteria include its P-channel logic-level drive compatibility (V_GS(th) = 1 V), thermal resistance (78 °C/W), and fast switching performance (t_d(off) = 42 ns, t_f = 15 ns) in space-constrained power stages.

Technical Context

This device employs ST's StripFET™ II process to achieve high cell density and low on-resistance while maintaining robust safe operating area (SOA) and unclamped inductive switching capability. Its P-channel topology enables high-side load switching without level-shifting circuitry.

Designed for low-voltage, medium-current power control, it supports pulsed drain currents up to 8 A and exhibits low reverse recovery charge (Q_rr = 36.3 nC) and fast diode recovery (t_rr = 38 ns), critical for synchronous buck converter freewheeling paths.

Key Specifications

V_DS	60 V - Maximum blocking voltage for 24–48 V system rails
R_DS(on)	0.20 Ω (typ @ V_GS = 10 V) - Enables <100 mW conduction loss at 2 A
I_D (cont)	2 A @ T_C = 25°C - Supports compact PCB layout with minimal heatsinking
Q_g	5 nC - Reduces gate drive power and enables efficient 1–2 MHz switching
t_f	15 ns - Limits switching losses during turn-off transitions
V_GS(th)	1 V (min) - Compatible with 1.8–3.3 V logic-level control signals
T_j(max)	150 °C - Allows operation in thermally constrained portable enclosures

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si2301DS	R_DS(on) = 0.115 Ω @ V_GS = 4.5 V; lower V_DS (20 V); smaller Q_g (2.3 nC)	Limited to ≤24 V systems; better for ultra-low-voltage logic-driven loads	Select when operating below 20 V and prioritizing gate drive efficiency over voltage margin
DMN2020LK	R_DS(on) = 0.12 Ω @ V_GS = 4.5 V; higher I_D (3.5 A); same 60 V rating	Higher current capacity but larger SOT-23-6 footprint (3.0 × 2.8 mm vs 2.8 × 2.6 mm)	Select when >2 A continuous current or improved thermal derating is required

Compared with Si2301DS and DMN2020LK, STT2PF60L offers optimal balance of 60 V rating, 0.20 Ω R_DS(on), and compact SOT-23-6L size - making it uniquely suited for space-limited 24–48 V portable power stages where voltage headroom and thermal density are both critical.

FAQ

Is STT2PF60L still in active production?

No - STMicroelectronics has marked STT2PF60L as obsolete (DocRev3, December 2005). However, Aetrix Electronics maintains legacy inventory and supports design-in continuity through verified surplus and authorized channel sources with full traceability and date-code matching.

Can STT2PF60L be used in 3.3 V gate-drive applications?

Yes - with V_GS(th) min = 1 V and R_DS(on) = 0.24 Ω @ V_GS = 4.5 V, it fully turns on using standard 3.3 V GPIO or LDO outputs. At 3.3 V, R_DS(on) rises to ~0.27 Ω, yielding ~540 mW loss at 2 A - acceptable for intermittent duty cycles.

What is the thermal performance of STT2PF60L on a standard PCB?

When mounted on a 1 in² pad of 2 oz copper on FR-4, R_thJ-amb = 78 °C/W. At 1.6 W dissipation and 25 °C ambient, junction temperature reaches ~145 °C - within the 150 °C limit. Derating to 1.3 A at 100 °C case temperature ensures long-term reliability.

Does STT2PF60L include an integrated Schottky diode?

No - it uses the intrinsic body diode formed by the MOSFET structure. This diode has V_SD = 1.2 V @ 2 A and t_rr = 38 ns, which is faster and lower-loss than discrete Schottky diodes in many 1–2 MHz DC-DC applications, but lacks independent optimization.
