Product details

Overview

2SK3576-T1B-AT from Renesas Electronics is an N-channel MOSFET designed for low-voltage switching applications, featuring 2.5 V gate drive capability, R_DS(on) ≤ 75 mΩ at V_GS = 2.5 V / I_D = 2.0 A, ±4.0 A DC drain current, and SC-96 surface-mount package. It serves as a power switch in portable electronics where space and low-threshold drive are critical.

For engineers reviewing the 2SK3576-T1B-AT datasheet, 2SK3576-T1B-AT pinout, 2SK3576-T1B-AT application, or 2SK3576-T1B-AT equivalent, key selection criteria include verified 2.5 V logic-level compatibility, body diode forward voltage (V_F(S-D) = 0.89 V), transient thermal resistance profile, and FR-4 board-mounted power dissipation limits (1.25 W).

Technical Context

This discrete MOSFET operates in enhancement mode with gate cutoff voltage V_GS(off) between 0.5 V and 1.5 V, enabling reliable turn-off under low-bias conditions. Its forward transfer admittance |y_fs| ≥ 1.0 S at V_DS = 10 V / I_D = 2.0 A confirms strong transconductance for fast switching transitions.

Switching performance is characterized by t_d(on) = 28 ns, t_r = 140 ns, t_d(off) = 110 ns, and t_f = 180 ns under defined test conditions (V_DD = 10 V, I_D = 2.0 A, R_G = 10 Ω), supported by total gate charge Q_G = 3.3 nC and Q_GD = 1.5 nC - indicating moderate drive strength requirements for efficient PWM control.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20 V - maximum blocking voltage compatible with 3.3 V and 5 V system rails
R_DS(on) @ 2.5 V	75 mΩ max - enables direct drive from low-voltage microcontrollers without level-shifting
I_D(DC)	±4.0 A - continuous current handling suitable for battery-powered load switching
Q_G	3.3 nC - determines gate driver current requirement for <200 ns switching transitions
V_GS(off)	0.5–1.5 V - ensures full turn-off with 0 V gate bias in battery-backed or standby circuits
V_F(S-D)	0.89 V - low body diode conduction loss during synchronous rectification or flyback recovery
C_iss	250 pF - impacts high-frequency gate drive impedance and EMI filtering design

Pinout & Package

2SK3576-T1B-AT uses the SC-96 (Mini Mold Thin Type) package - a 3-pin, surface-mount, lead-free outline measuring 2.9 mm × 1.5 mm × 0.65 mm, optimized for compact portable PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Receives logic-level gate voltage; requires external ESD protection per datasheet note
2 (Source)	Reference node	Common return path for load current; tied to ground or low-side reference in typical switch configurations
3 (Drain)	Power output terminal	Connects to switched load or supply rail; carries full load current and dissipates on-state power

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AO3400	R_DS(on) = 44 mΩ @ V_GS = 4.5 V; no specified R_DS(on) at 2.5 V; higher C_iss (490 pF)	Better conduction at 4.5 V, but less reliable 2.5 V turn-on margin	Select when gate drive is stable ≥4.5 V and lower on-resistance is prioritized over ultra-low-voltage compatibility
SI2300DS	R_DS(on) = 60 mΩ @ V_GS = 2.5 V; same SC-96 package; higher I_D(pulse) = 24 A	Superior pulse current rating and tighter V_GS(off) distribution (0.4–1.2 V)	Prefer for high-reliability portable designs requiring guaranteed 2.5 V turn-on with margin against process variation

Compared with AO3400 and SI2300DS, the 2SK3576-T1B-AT offers the most rigorously specified R_DS(on) at 2.5 V (75 mΩ max), validated gate cutoff range (0.5–1.5 V), and documented FR-4 board thermal performance - making it optimal for cost-sensitive, space-constrained 2.5 V–3.3 V switching where datasheet-guaranteed low-threshold behavior is mandatory.

FAQ

What is the maximum continuous drain current for the 2SK3576-T1B-AT?

The 2SK3576-T1B-AT supports ±4.0 A DC drain current at T_A = 25°C when mounted on an FR-4 board. Derating applies above 25°C ambient; at 70°C, usable current drops to approximately ±2.5 A based on the published derating curve in the D15939EJ1V0DS datasheet. This rating assumes proper PCB copper area and airflow per Renesas' thermal test conditions.

Does the 2SK3576-T1B-AT have built-in ESD protection?

Yes, the 2SK3576-T1B-AT integrates a gate-source protection diode for basic ESD immunity. However, the datasheet explicitly states that "an additional protection circuit is externally required if a voltage exceeding the rated voltage may be applied." Therefore, system-level ESD protection (e.g., TVS diode at the gate) remains mandatory for IEC 61000-4-2 compliance.

Can the 2SK3576-T1B-AT be used with a 2.5 V microcontroller GPIO?

Yes - the 2SK3576-T1B-AT is explicitly characterized for 2.5 V drive: R_DS(on) ≤ 75 mΩ is guaranteed at V_GS = 2.5 V and I_D = 2.0 A. Its V_GS(off) range (0.5–1.5 V) ensures full turn-off with 0 V gate bias, making it suitable for direct interface with 2.5 V logic without level-shifting circuitry.

What is the thermal resistance of the 2SK3576-T1B-AT on FR-4 board?

The 2SK3576-T1B-AT achieves a total power dissipation of 1.25 W when mounted on a standard FR-4 board (50 mm × 50 mm × 1.6 mm). While the datasheet does not specify junction-to-ambient (R_θJA) as a single value, the derating curve shows linear reduction from 1.25 W at 25°C to 0 W at ~150°C ambient - implying an effective R_θJA ≈ 100°C/W under those specific board conditions.

Is the 2SK3576-T1B-AT RoHS compliant?

Yes - the 2SK3576-T1B-AT is lead-free and RoHS compliant, consistent with Renesas Electronics' environmental policy stated in the D15939EJ1V0DS datasheet and confirmed by its SC-96 package marking and manufacturing date (2002 onward). It meets EU Directive 2011/65/EU requirements for restricted substances.
