Product details

Overview

2SK2736-E from Renesas Electronics is a silicon N-channel MOSFET designed for high-speed power switching applications, featuring R_DS(on) = 20 mΩ (typ.) at V_GS = 10 V and I_D = 15 A, 30 V V_DSS, and 30 A continuous drain current. It supports 4 V gate drive and delivers fast switching with t_d(on) = 16 ns and t_f = 90 ns, commonly used in DC-DC converters and motor drive half-bridges.

For engineers reviewing the 2SK2736-E datasheet, 2SK2736-E pinout, 2SK2736-E application, or 2SK2736-E equivalent, key selection criteria include low on-resistance at 4 V gate drive, body diode reverse recovery time (t_rr = 45 ns), thermal resistance (θ_ch-c = 5.0°C/W), and TO-220CFM package compatibility with heatsink mounting.

Technical Context

The 2SK2736-E employs a planar vertical DMOS structure optimized for low conduction loss and fast switching in hard-switched topologies. Its gate threshold voltage (V_GS(off) = 1.0–2.0 V) enables reliable turn-on with standard logic-level drivers, while its C_iss = 750 pF and C_rss = 210 pF support stable gate control under high dv/dt conditions.

Designed for unidirectional power flow, it integrates a robust body diode with V_DF = 1.0 V (I_F = 30 A) and t_rr = 45 ns, enabling efficient freewheeling in buck and flyback converters without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - Maximum blocking voltage in off-state; sets upper limit for input/output rail voltage in step-down or H-bridge stages.
R_DS(on) @ 10 V	20 mΩ typ. - Conduction loss of ~4.5 W at 15 A; determines thermal design margin and efficiency in continuous conduction mode.
I_D (continuous)	30 A - Steady-state current capability at T_c = 25°C; requires heatsinking to sustain full rating in real-world PCB layouts.
t_r/t_f	260 ns / 90 ns - Rise/fall times define minimum achievable switching frequency and EMI profile in PWM circuits.
t_rr	45 ns - Body diode reverse recovery time; critical for minimizing shoot-through risk and voltage spikes in synchronous rectification.
Q_g	Not specified in provided data - Gate charge not listed; design must rely on C_iss/C_rss values for driver sizing.
P_ch	25 W @ T_c = 25°C - Channel dissipation limit defines safe operating area boundary under pulse or DC load conditions.

Pinout & Package

2SK2736-E is housed in the TO-220CFM (RENESAS code PRSS0003AE-A) package - a variant of TO-220 with insulated tab and metal backside for direct heatsink mounting. The case is electrically connected to the drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Receives gate drive signal; requires ≥4 V to fully enhance; sensitive to ESD and overvoltage (±20 V max).
2 (Drain)	High-side power terminal	Connected to switched high-voltage rail; electrically tied to metal tab and heatsink surface.
3 (Source)	Power return/reference node	Serves as local ground reference for gate drive; carries full load current and influences layout grounding strategy.

Key Features

Feature	Design Value
Low R_DS(on) at 4 V drive	R_DS(on) = 35 mΩ typ. at V_GS = 4 V - Enables direct interface with 3.3 V/5 V microcontrollers without level-shifting circuitry.
Fast switching performance	t_d(on) = 16 ns, t_f = 90 ns - Reduces switching losses in high-frequency DC-DC converters (>100 kHz).
Integrated body diode	V_DF = 1.0 V @ 30 A, t_rr = 45 ns - Supports freewheeling in non-synchronous topologies with predictable voltage drop and recovery behavior.
Thermal robustness	θ_ch-c = 5.0°C/W - Allows 5°C temperature rise per watt dissipated when mounted on adequately sized heatsink.

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
STP30NF20	V_DSS = 200 V, R_DS(on) = 42 mΩ @ 10 V, TO-220FP package (drain-isolated)	Higher voltage rating suits 100–200 V systems; higher R_DS(on) increases conduction loss at 15 A	Select when >30 V blocking is required and gate drive ≥10 V is available.
IRFZ44NPBF	V_DSS = 55 V, R_DS(on) = 28 mΩ @ 10 V, TO-220AB package (non-insulated tab)	Wider voltage margin but no drain-isolation; requires insulating pad for heatsink mounting	Choose for cost-sensitive 48 V bus designs where isolation is managed externally.

Compared with STP30NF20 and IRFZ44NPBF, the 2SK2736-E offers optimal balance of low 30 V V_DSS, 4 V logic-level drive, and TO-220CFM insulation - making it uniquely suited for compact, thermally constrained 24–30 V power stages where gate drive voltage and heatsink safety are design priorities.

FAQ

What is the maximum gate-to-source voltage rating for the 2SK2736-E?

The 2SK2736-E has a maximum gate-to-source voltage rating (V_GSS) of ±20 V. Exceeding this limit risks permanent gate oxide damage. Designers must ensure gate drive circuits - including transient spikes from parasitic inductance - remain within this range, especially during hot-plug or fault conditions. The 2SK2736-E datasheet specifies this absolute maximum under all operating conditions.

Does the 2SK2736-E support logic-level gate drive?

Yes, the 2SK2736-E supports logic-level gate drive with guaranteed R_DS(on) = 35 mΩ (typ.) at V_GS = 4 V and I_D = 15 A. Its gate threshold voltage (V_GS(off)) ranges from 1.0 V to 2.0 V, allowing full enhancement using standard 3.3 V or 5 V microcontroller outputs. This eliminates need for gate driver ICs in many low-to-moderate power applications involving the 2SK2736-E.

What is the thermal resistance from channel to case for the 2SK2736-E?

The channel-to-case thermal resistance (θ_ch-c) of the 2SK2736-E is 5.0°C/W, measured at T_c = 25°C. This value applies when the device is mounted to a heatsink with proper mechanical pressure and thermal interface material. It directly determines junction temperature rise under steady-state power dissipation and is critical for reliability validation in the 2SK2736-E's target applications.

Can the 2SK2736-E be used in synchronous rectification?

The 2SK2736-E can be used in synchronous rectification, but only in topologies where its body diode characteristics are acceptable. With t_rr = 45 ns and V_DF = 1.0 V at 30 A, it performs well in medium-frequency flyback or forward converters. However, its lack of specified Q_rr and absence of optimized body diode softness limit suitability in high-frequency ZVS or resonant designs where the 2SK2736-E may generate excessive ringing or loss.

Is the metal tab of the 2SK2736-E electrically isolated?

Yes, the metal tab of the 2SK2736-E is electrically isolated from internal circuitry and connected solely to the drain terminal. Its TO-220CFM package (RENESAS code PRSS0003AE-A) features an insulated mounting surface, enabling direct attachment to grounded heatsinks without additional isolation hardware. This simplifies thermal management and improves system safety in the 2SK2736-E's implementation.
