Product details

Overview

2SK2054-T1-AZ from Renesas Electronics is an N-channel vertical MOSFET designed for high-speed switching in DC/DC converters and actuator drivers. It features R_DS(on) = 0.25 Ω max at V_GS = 4 V, 1.5 A; V_DSS = 60 V; I_D(DC) = ±3.0 A; and direct 5-V IC drivability - enabling compact, efficient low-voltage power switching.

For engineers reviewing the 2SK2054-T1-Az datasheet, 2SK2054-T1-AZ pinout, 2SK2054-T1-AZ application, or 2SK2054-T1-AZ equivalent, key selection criteria include verified 60-V drain-source rating, sub-0.25-Ω on-resistance at 4-V gate drive, pulse current capability up to ±6.0 A, thermal derating behavior on ceramic substrates, and gate protection diode integration.

Technical Context

This discrete MOSFET employs a vertical structure optimized for fast switching with low conduction loss. Its gate threshold voltage (V_GS(off) = 0.8–2.0 V) ensures reliable turn-on from standard logic-level outputs, while integrated gate protection diode and source-drain body diode support robust operation in inductive load circuits.

Switching performance is characterized by t_d(on) = 6 ns, t_r = 80 ns, t_d(off) = 70 ns, and t_f = 25 ns under defined test conditions (V_DD = 10 V, I_D = 1.5 A, R_G = 10 Ω), confirming suitability for high-frequency DC/DC topologies operating below 500 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - supports input rails up to 48-V systems without derating
R_DS(on) @ 4 V	0.25 Ω max - enables <1 W conduction loss at 2 A DC in TO-220AF package
I_D(DC)	±3.0 A - rated continuous current with 2.0 W dissipation on 7.5 cm² ceramic substrate
t_r / t_f	80 ns / 25 ns - supports clean edge transitions in PWM-driven motor or converter stages
C_iss	530 pF - determines gate drive strength requirement for 100-kHz+ switching

P_T	2.0 W - defines maximum steady-state power handling with specified heatsinking

Pinout & Package

2SK2054-T1-AZ is housed in a TO-220AF (straight lead, insulated tab) package with 3 terminals. The plastic case provides electrical isolation between drain and mounting surface, supporting direct heatsink attachment without insulator washers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFZ44NPBF	R_DS(on) = 0.028 Ω @ 10 V (lower), but V_GS(th) = 2–4 V - less reliable at 3.3 V drive	Requires ≥4.5 V gate drive for full enhancement; unsuitable for direct 3.3-V MCU interface	Prefer when higher current (>5 A) and 10-V gate availability exist; avoid in 3.3-V logic systems
STP3NK60Z	V_DSS = 600 V (higher), R_DS(on) = 4.5 Ω @ 10 V (much higher), slower switching	Designed for offline SMPS, not low-voltage DC/DC - excessive on-resistance at 12 V	Only suitable for high-voltage flyback or PFC; incompatible for 24-V actuator or buck converter use

Compared with IRFZ44NPBF and STP3NK60Z, the 2SK2054-T1-AZ uniquely balances 60-V rating, 0.25-Ω R_DS(on) at 4 V, and 3.3–5 V logic compatibility - making it optimal for space-constrained, low-voltage industrial switching where gate drive simplicity and thermal efficiency are jointly critical.

FAQ

What is the maximum continuous drain current rating for the 2SK2054-T1-AZ?

The 2SK2054-T1-AZ has a maximum continuous drain current (I_D(DC)) of ±3.0 A at T_A = 25 °C with specified heatsinking (7.5 cm² ceramic substrate). This rating decreases per the derating curve above 25 °C ambient, reaching zero at 125 °C. Actual usable current depends on PCB layout, airflow, and thermal interface - the 2SK2054-T1-AZ must be mounted with its insulated tab to a thermally adequate heatsink to sustain rated current.

Does the 2SK2054-T1-AZ support direct drive from a 3.3-V microcontroller output?

Yes - the 2SK2054-T1-AZ has a gate threshold voltage (V_GS(off)) range of 0.8–2.0 V and guarantees R_DS(on) ≤ 0.25 Ω at V_GS = 4 V, 1.5 A. When driven with 3.3 V, it achieves partial enhancement sufficient for many low-duty-cycle or low-current applications. For full 3.0-A conduction, 4–5 V gate drive is recommended; the 2SK2054-T1-AZ remains functional but with elevated R_DS(on) at 3.3 V.

What is the purpose of the internal gate protection diode in the 2SK2054-T1-AZ?

The internal gate protection diode in the 2SK2054-T1-AZ is a Zener-type clamp between gate and source, rated for ±20 V. It safeguards the thin gate oxide from electrostatic discharge (ESD) and transient overvoltage during handling or circuit operation. This feature allows safe manual assembly and improves system-level robustness without requiring external gate resistors or TVS diodes - a key reliability advantage of the 2SK2054-T1-AZ in industrial environments.

Can the 2SK2054-T1-AZ replace a bipolar junction transistor in a 24-V relay driver?

Yes - the 2SK2054-T1-AZ can directly replace a BJT in low-side 24-V relay driver circuits. Its low gate charge and logic-compatible threshold eliminate base-drive resistors and reduce MCU GPIO loading. Unlike BJTs, the 2SK2054-T1-AZ exhibits no saturation voltage drop - resulting in lower power loss and cooler operation. Ensure the relay coil flyback diode is retained, as the 2SK2054-T1-AZ's body diode is not rated for continuous reverse recovery in this configuration.

Is the 2SK2054-T1-AZ RoHS compliant and halogen-free?

Yes - the 2SK2054-T1-AZ complies with EU RoHS Directive 2011/65/EU and is halogen-free per Renesas' environmental specifications. Lead-free terminations and compliant molding compounds were implemented across the 2SK2054 product family prior to discontinuation. Full material declarations and test reports for the 2SK2054-T1-AZ are available through Renesas' official product change notifications and environmental compliance portal.
