Product details

Overview

2SK1566-E from Renesas Electronics is a silicon N-channel power MOSFET in TO-220FM package, rated for 450 V V_DSS, 7 A continuous drain current, and 0.6–0.8 Ω R_DS(on) at V_GS = 10 V. It delivers low on-resistance, high-speed switching, and no secondary breakdown-optimized for DC-DC converters and switching regulators in industrial power supplies.

For engineers reviewing the 2SK1566-E datasheet, 2SK1566-E pinout, 2SK1566-E application, or 2SK1566-E equivalent, key selection criteria include its 450 V blocking capability, 35 W channel dissipation at T_C = 25°C, 15 ns turn-on delay, 95 ns turn-off delay, and body diode reverse recovery time of 320 ns under specified test conditions.

Technical Context

This MOSFET employs a planar vertical DMOS structure with optimized gate oxide and drift region design to achieve stable high-voltage operation without secondary breakdown. Its low input capacitance (C_iss = 1050 pF) and reverse transfer capacitance (C_rss = 40 pF) support fast switching with reduced Miller effect.

The device integrates an intrinsic body diode with V_DF = 0.95 V at I_F = 7 A and t_rr = 320 ns under di_F/dt = 100 A/µs-enabling synchronous rectification and freewheeling in hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	450 V - supports primary-side switching in offline 380 V DC bus and 230 V AC-input SMPS
R_DS(on)	0.6–0.8 Ω @ I_D = 4 A, V_GS = 10 V - enables <1.3 W conduction loss at 4 A, reducing heatsink requirements
t_d(on)/t_d(off)	15 ns / 95 ns - allows >500 kHz switching in resonant and hard-switched converters
C_iss/C_oss	1050 pF / 280 pF @ V_DS = 10 V - minimizes gate drive energy and improves EMI profile
t_rr	320 ns - limits reverse recovery loss in flyback and forward converters operating below 200 kHz
P_ch	35 W @ T_C = 25°C - defines maximum steady-state power handling with adequate heatsinking
T_ch	150°C - sets thermal derating limit for reliable long-term operation in enclosed enclosures

Pinout & Package

2SK1566-E uses the TO-220FM (RENESAS code PRSS0003AD-A) package: insulated tab, single-row 3-pin through-hole mounting, 1.8 g mass, and standard 2.54 mm lead pitch. The metal tab is electrically connected to the Drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Controls channel conduction; requires ≤±30 V gate-source voltage and low-impedance drive for fast switching
2 (D)	Drain	High-voltage output node; connected to heatsink via insulated mounting; carries full load current during conduction
3 (S)	Source	Reference node for gate drive; tied to power ground or low-side switch node; returns load current

Key Features

Feature	Design Value
No secondary breakdown	Enables safe operation across full SOA without current crowding or thermal runaway in linear or switching modes
Low drive current requirement	Q_g not specified but inferred from C_iss/C_rss values - reduces gate driver IC stress and PCB layout complexity
High-speed switching	Combined t_d(on) + t_r + t_d(off) + t_f ≈ 195 ns - supports efficient operation up to 1 MHz in ZVS/ZCS topologies
Suitable for switching regulator	Validated in reference designs for buck, flyback, and forward converters per Renesas application notes
Body diode with defined t_rr	320 ns reverse recovery time enables predictable snubber design and loss estimation in discontinuous conduction mode

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
STP4NK50ZFP	500 V V_DSS, 4 A I_D, 1.4 Ω R_DS(on), TO-220FP package (non-insulated tab)	Lower current rating and higher on-resistance; unsuitable for >4 A continuous loads	Select when 500 V margin is critical and load current remains ≤4 A; verify heatsink isolation if using insulated mounting.
IXTP12N50D2	500 V V_DSS, 12 A I_D, 0.55 Ω R_DS(on), TO-220AB package (non-insulated tab)	Higher current and lower R_DS(on), but lacks specified t_rr and no secondary breakdown guarantee	Prefer for higher-current designs where SOA robustness is less critical than conduction efficiency; requires external snubber if used in hard-switched flyback.

Compared with STP4NK50ZFP and IXTP12N50D2, the 2SK1566-E offers superior SOA integrity and verified body diode performance at 450 V/7 A-making it optimal for reliability-critical switching regulator stages where transient overloads and reverse recovery behavior must be tightly controlled.

FAQ

What is the maximum continuous drain current rating for the 2SK1566-E?

The 2SK1566-E is rated for 7 A continuous drain current (I_D) at T_C = 25°C. This rating assumes proper heatsinking and derates linearly above 25°C case temperature per the published thermal impedance curve. At T_C = 100°C, the usable I_D drops to approximately 4.2 A to maintain safe channel temperature limits.

Does the 2SK1566-E have a built-in body diode, and what are its key parameters?

Yes, the 2SK1566-E integrates a monolithic body diode with V_DF = 0.95 V at I_F = 7 A and reverse recovery time t_rr = 320 ns under di_F/dt = 100 A/µs and V_GS = 0. These values are measured and guaranteed per the official Renesas datasheet Rev. 2.00, enabling accurate loss modeling in flyback and forward converter designs.

Is the 2SK1566-E pin-compatible with the 2SK1567-E?

No-the 2SK1566-E and 2SK1567-E share identical TO-220FM package and pinout (G-D-S), but they differ in voltage rating (450 V vs. 500 V) and R_DS(on) (0.6–0.8 Ω vs. 0.7–0.9 Ω). They are mechanically interchangeable but electrically distinct; substituting one for the other requires verification of voltage margin and thermal performance in the target application.

What is the gate-to-source voltage limit for the 2SK1566-E?

The 2SK1566-E has a maximum gate-to-source voltage rating (V_GSS) of ±30 V. Exceeding this value risks permanent gate oxide damage. Recommended gate drive is 10–15 V for full enhancement, with fast turn-on/turn-off achieved using low-impedance drivers capable of sourcing/sinking ≥1 A peak current to manage Q_g-related timing.

Can the 2SK1566-E be used in avalanche-rated applications?

No-Renesas does not specify or guarantee avalanche energy rating (E_AS) for the 2SK1566-E. The device is characterized for operation within its Safe Operating Area (SOA) under clamped inductive switching, but intentional avalanche operation is outside its qualified use case and may result in parametric shift or failure.
