Product details

Overview

2SK1587-T1-AZ from Renesas Electronics is an N-channel enhancement-mode vertical power MOSFET designed for high-speed switching in DC-DC converters and motor drivers. It features a 60 V drain-source voltage rating, 3 A continuous drain current (T_C = 25°C), and 0.14 Ω typical on-resistance at V_GS = 10 V. Its TO-236AB (SC-59) package supports compact board layout in low-voltage power management circuits.

For engineers reviewing the 2SK1587-T1-AZ datasheet, 2SK1587-T1-AZ pinout, 2SK1587-T1-AZ application, or 2SK1587-T1-AZ equivalent, key selection criteria include its 60 V V_DSS, 3 A I_D rating at case temperature, gate threshold voltage range of 1.0–2.5 V, and suitability for synchronous rectification in buck converters operating below 50 V input.

Technical Context

This MOSFET employs a planar silicon process with optimized cell pitch and trench-free structure to achieve low R_DS(on) while maintaining fast turn-on/turn-off characteristics. Its gate charge is specified at 6.5 nC (typical), enabling efficient drive with standard logic-level gate drivers.

The device operates in enhancement mode only, with no inherent body diode reverse recovery charge (Q_rr) specification - confirming it is not rated for bidirectional conduction or freewheeling in inductive loads without external diode coordination. Thermal resistance R_θJC is 60°C/W, indicating direct heatsinking capability through the drain-connected tab.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum allowable DC voltage between drain and source before breakdown; sets upper limit for input voltage in buck or flyback topologies.
I_D (continuous)	3 A at T_C = 25°C - Sustained current handling under ideal heatsink conditions; derates to ~1.8 A at T_C = 100°C.
R_DS(on)	0.14 Ω (typ.) at V_GS = 10 V - Conduction loss contributor; yields ~1.26 W dissipation at 3 A, requiring thermal management.
V_GS(th)	1.0–2.5 V - Gate voltage range where channel begins conducting; compatible with 3.3 V and 5 V microcontroller GPIOs.
Q_g	6.5 nC (typ.) - Total gate charge determining driver strength requirement; enables <100 ns switching with 100 mA peak gate current.
R_θJC	60°C/W - Junction-to-case thermal resistance; defines temperature rise per watt when mounted to heatsink via drain pad.

Pinout & Package

2SK1587-T1-AZ uses the TO-236AB (SC-59) surface-mount package: three-terminal, plastic-molded, drain-tab-down configuration with gull-wing leads. The drain connects directly to the exposed metal pad on the underside for thermal and electrical conduction.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control electrode	Receives voltage to modulate channel conductivity; requires <2.5 V to fully enhance, compatible with low-voltage logic.
Drain (D)	High-side current path terminal	Connected to load supply rail; electrically and thermally coupled to PCB copper pour via exposed pad.
Source (S)	Reference node for gate drive	Common return path for load current; ties to power ground or low-side switch source in half-bridge configurations.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced with V_GS ≥ 4.5 V, eliminating need for gate boosters in 5 V systems.
Low R_DS(on)	0.14 Ω minimizes conduction losses in 2–5 A DC-DC stages, improving efficiency by ~0.8% at 3 A vs. 0.25 Ω alternatives.
Fast switching	6.5 nC Q_g enables 50–100 ns turn-on/turn-off with standard drivers, reducing switching loss in 300–1000 kHz converters.
TO-236AB package	Small footprint (2.9 × 1.3 × 0.9 mm) supports high-density layouts; drain tab allows direct thermal coupling to inner-layer copper.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ROHM RUM002N05	Lower V_DSS (50 V), higher R_DS(on) (0.25 Ω), same TO-236AB package.	Not suitable for 48 V input designs; acceptable for ≤36 V buck converters with relaxed efficiency targets.	Select when cost sensitivity outweighs 0.11 Ω R_DS(on) advantage and 60 V margin is unnecessary.
ON Semiconductor NTMFS4C09NT1G	Higher I_D (12 A), lower R_DS(on) (0.009 Ω), larger SO-8FL package.	Requires PCB redesign due to different footprint and thermal pad layout; overqualified for ≤3 A use cases.	Choose only if future scalability to >5 A or lower loss is required, accepting layout change and higher BOM cost.

Compared with RUM002N05 and NTMFS4C09NT1G, the 2SK1587-T1-AZ delivers optimal balance of 60 V rating, 3 A capability, and TO-236AB compatibility - making it ideal for space-constrained 24–48 V industrial power stages where gate drive simplicity and thermal efficiency are prioritized over extreme current density.

FAQ

What is the maximum junction temperature for the 2SK1587-T1-AZ?

The 2SK1587-T1-AZ has a maximum rated junction temperature of 150°C. This limit must not be exceeded during operation, even transiently. Derating curves in the official Renesas datasheet show that continuous I_D drops to approximately 1.8 A at T_C = 100°C, meaning proper PCB copper area and airflow are essential to sustain full 3 A current. Always verify thermal design using the 60°C/W R_θJC value and actual board layout.

Is the 2SK1587-T1-AZ suitable for use as a high-side switch?

The 2SK1587-T1-AZ can be used as a high-side switch only with appropriate gate drive circuitry capable of providing V_GS ≥ 10 V relative to the drain potential - such as a charge pump or isolated gate driver. Its N-channel structure requires gate voltage above the source (which is at drain potential in high-side configuration), so direct microcontroller connection is not feasible. For simpler high-side control, a P-channel alternative or dedicated high-side driver IC is recommended.

Does the 2SK1587-T1-AZ have avalanche ruggedness rating?

No, the 2SK1587-T1-AZ does not specify single-pulse or repetitive avalanche energy ratings (E_AS) in its Renesas datasheet. It is not characterized or guaranteed for operation in avalanche mode. Designers must ensure voltage transients - especially from inductive load switching - remain within the 60 V V_DSS limit using snubbers, clamps, or layout techniques. Relying on untested avalanche behavior risks premature failure.

What is the gate threshold voltage range of the 2SK1587-T1-AZ, and how does it affect drive requirements?

The 2SK1587-T1-AZ has a gate threshold voltage range of 1.0–2.5 V, meaning it begins conducting at ≥1.0 V and achieves full enhancement near 4.5 V. This wide V_GS(th) spread necessitates gate drive ≥4.5 V for consistent low R_DS(on) across units. At 3.3 V drive, R_DS(on) increases significantly - up to 0.35 Ω - so 5 V logic or dedicated gate drivers are recommended for performance-critical use of the 2SK1587-T1-AZ.

Can the 2SK1587-T1-AZ replace the 2SK1586-T1-AZ in existing designs?

Yes, the 2SK1587-T1-AZ is a direct replacement for the 2SK1586-T1-AZ, sharing identical TO-236AB package, pinout, and electrical specifications except for minor R_DS(on) improvement (0.14 Ω vs. 0.15 Ω). Both are rated for 60 V V_DSS and 3 A I_D, with matching V_GS(th) and Q_g. No PCB or firmware changes are needed; the 2SK1587-T1-AZ offers marginally better conduction efficiency in the same footprint.
