Product details

Overview

2SK2111(0)-T1-AZ from Renesas Electronics is an N-channel vertical MOSFET designed for high-speed switching in low-voltage IC-driven circuits. It features R_DS(on) ≤ 0.6 Ω at V_GS = 4.0 V and I_D = 0.5 A, t_on + t_off < 100 ns, and operates up to 60 V V_DSS, making it suitable for DC/DC converter primary-side switches and small motor drivers.

For engineers reviewing the 2SK2111(0)-T1-AZ datasheet, 2SK2111(0)-T1-AZ pinout, 2SK2111(0)-T1-AZ application, or 2SK2111(0)-T1-AZ equivalent, key selection criteria include guaranteed low gate threshold (V_GS(off) = 0.8–2.0 V), verified 1.0 A DC current rating, ceramic-substrate power dissipation (2.0 W), and confirmed TO-236AA (SC-59) package compatibility with surface-mount actuator control layouts.

Technical Context

This device uses a vertical DMOS structure optimized for direct 5 V logic-level drive without external level shifting. Its low C_iss (170 pF) and C_rss (32 pF) enable fast switching with minimal Miller effect, while the integrated body diode supports unidirectional flyback recovery in inductive loads.

The 2SK2111(0)-T1-AZ is rated for continuous operation up to T_ch = 150 °C and exhibits monotonic R_DS(on) increase with temperature-0.32 Ω typical at 25 °C rising to ~0.5 Ω at 75 °C under V_GS = 4 V-enabling predictable thermal derating in compact PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Supports input rails up to 48 V nominal systems with margin for transient spikes
R_DS(on) max	0.6 Ω @ V_GS = 4.0 V, I_D = 0.5 A - Enables <1.5 W conduction loss at 0.5 A, suitable for space-constrained DC/DC stages
t_on + t_off	< 100 ns - Meets sub-10 MHz hard-switching requirements in synchronous buck converters
C_iss	170 pF - Low input capacitance reduces gate drive power and enables clean 10 Ω RG turn-on
V_GS(off)	0.8–2.0 V - Ensures reliable enhancement-mode turn-off with standard 3.3 V/5 V logic outputs
P_T	2.0 W on 16 cm² × 0.7 mm ceramic substrate - Defines heatsink area requirement for continuous 1 A operation

Pinout & Package

2SK2111(0)-T1-AZ is housed in a TO-236AA (SC-59) plastic surface-mount package with gull-wing leads, 2.5 mm × 4.5 mm footprint, and 1.6 mm height. Pin 1 = Gate (G), Pin 2 = Drain (D), Pin 3 = Source (S); marking "NU" identifies the device on-body.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control terminal	Accepts 0–20 V logic-level signals; requires no external pull-down due to defined V_GS(off) range

FAQ

What is the maximum continuous drain current rating for the 2SK2111(0)-T1-AZ?

The 2SK2111(0)-T1-AZ has a maximum continuous drain current (I_D(DC)) rating of ±1.0 A at T_A = 25 °C, derated linearly to zero at 150 °C channel temperature. This rating assumes use on a 16 cm² × 0.7 mm ceramic substrate per the datasheet test condition. Actual usable current depends on PCB copper area, ambient temperature, and airflow-designers should consult the SOA curves on page 3 of the 2SK2111(0)-T1-AZ datasheet for safe operating boundaries.

Does the 2SK2111(0)-T1-AZ have an integrated body diode, and what are its specifications?

Yes, the 2SK2111(0)-T1-AZ includes an integrated source-to-drain body diode. Its forward voltage (V_SD) is approximately 0.8 V at I_SD = 0.5 A and T_A = 25 °C, as shown in the Typical Characteristics chart on page 5 of the 2SK2111(0)-T1-AZ datasheet. The diode is rated for continuous forward current up to 0.5 A and supports unidirectional freewheeling in inductive load applications such as motor drives and relay interfaces.

Is the 2SK2111(0)-T1-AZ suitable for 3.3 V logic-level gate drive?

The 2SK2111(0)-T1-AZ is specified for full enhancement at V_GS = 4.0 V, with V_GS(off) ranging from 0.8 V to 2.0 V. While it may conduct partially at 3.3 V, the datasheet does not guarantee R_DS(on) or switching performance below 4.0 V. For reliable 3.3 V operation, consider verifying actual R_DS(on) and t_on/t_off in-system or selecting a MOSFET explicitly characterized down to 3.3 V, such as the 2SK2111(0)-T1-AZ's performance envelope remains valid only within its published test conditions.

What is the package type and lead finish of the 2SK2111(0)-T1-AZ?

The 2SK2111(0)-T1-AZ uses the TO-236AA (SC-59) surface-mount package with gull-wing leads, measuring 2.5 mm × 4.5 mm × 1.6 mm. Its lead finish is matte tin, compliant with JEDEC J-STD-020 moisture sensitivity level (MSL) 1, and RoHS-compliant per Renesas' environmental documentation. The device marking "NU" appears on the top surface, and pin 1 (Gate) is identified by the lead closest to the marking notch.

How does the 2SK2111(0)-T1-AZ perform under elevated temperature conditions?

The 2SK2111(0)-T1-AZ exhibits predictable thermal behavior: R_DS(on) increases from 0.32 Ω typical at 25 °C to ~0.5 Ω at 75 °C (V_GS = 4 V), and the forward transfer admittance |y_fs| decreases gradually with temperature. Its channel temperature limit is 150 °C, and the derating factor drops linearly from 100% at 25 °C to 0% at 150 °C. Designers must apply the SOA curves on page 3 of the 2SK2111(0)-T1-AZ datasheet to ensure safe operation across the full thermal range.
