Product details

Overview

2SK3114-S17-AZ from Renesas Electronics is an N-channel enhancement-mode DMOS power MOSFET in an isolated TO-220 package, rated for 600 V drain-source voltage, 4.0 A DC drain current, and 2.2 Ω maximum on-resistance at V_GS = 10 V. It delivers low gate charge (15 nC typ.) and avalanche-rated ruggedness for high-voltage switching in offline AC/DC power supplies and industrial adapters.

For engineers reviewing the 2SK3114-S17-AZ datasheet, 2SK3114-S17-AZ pinout, 2SK3114-S17-AZ application, or 2SK3114-S17-AZ equivalent, key selection criteria include its isolated TO-220 thermal performance (R_th(CH–C) = 4.17 °C/W), single-pulse avalanche energy (10.7 mJ), body diode reverse recovery characteristics (t_rr = 1.3 µs, Q_rr = 4.3 µC), and gate voltage rating (±30 V).

Technical Context

The 2SK3114-S17-AZ employs a double-diffused MOS (DMOS) structure optimized for high-voltage switching with low conduction and switching losses. Its gate threshold voltage (V_GS(off) = 2.5–3.5 V) ensures reliable turn-on under standard 10 V gate drive, while its forward transfer admittance (|y_fs| = 1.0–50 S) supports stable current gain across temperature.

Designed for hard-switched topologies, it features fully characterized dynamic parameters including turn-on delay (12 ns), rise time (6 ns), turn-off delay (35 ns), and fall time (12 ns) under defined test conditions (V_DD = 150 V, R_G = 10 Ω). Its isolated TO-220 package enables direct heatsinking without additional insulation hardware.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Supports primary-side switching in universal-input (85–265 VAC) offline SMPS without derating.
R_DS(on) max	2.2 Ω @ V_GS = 10 V, I_D = 2.0 A - Enables <10 W conduction loss at 4 A continuous, suitable for 50–100 W adapters.
Q_G typ	15 nC @ V_DD = 450 V - Reduces gate driver power demand and switching transition time in high-frequency designs.
E_AS	10.7 mJ - Withstands single-pulse inductive energy spikes up to 150 V × 4 A × 17.8 µs, enhancing system robustness.
t_rr / Q_rr	1.3 µs / 4.3 µC - Limits body diode reverse recovery loss during synchronous or quasi-resonant operation.
R_th(CH–C)	4.17 °C/W - Allows 30 W dissipation at ≤75 °C case temperature, supporting compact heatsink integration.

Pinout & Package

2SK3114-S17-AZ uses the isolated TO-220 (MP-45F) package: metal tab (Drain) electrically isolated from leads, enabling direct mounting to grounded heatsinks without insulating pads. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Receives 10 V logic-level gate drive; ±30 V absolute rating prevents ESD damage when used with external gate protection.
Pin 2 (Drain)	High-voltage power terminal	Connected to transformer primary or bus rail; isolated tab allows safe thermal coupling to chassis ground.
Pin 3 (Source)	Reference node for gate drive	Serves as return path for load current and gate drive loop; must be routed with low inductance to minimize switching oscillation.

Key Features

Feature	Design Value
Avalanche-rated ruggedness	Single-pulse I_AS = 4.0 A and E_AS = 10.7 mJ enable reliable operation under inductive fault conditions without external snubbers.
Low gate charge	Q_G = 15 nC reduces gate driver stress and improves efficiency in 50–100 kHz flyback and forward converters.
Isolated TO-220 package	Electrical isolation between Drain tab and leads eliminates need for insulating hardware, simplifying thermal design and reducing BOM cost.
Body diode with fast recovery	t_rr = 1.3 µs and Q_rr = 4.3 µC minimize cross-conduction loss in quasi-resonant topologies and improve light-load efficiency.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP6NK60ZFP	600 V, 5.5 A, R_DS(on) = 1.2 Ω, Q_G = 22 nC, TO-220FP (non-isolated)	Higher current rating but requires insulated mounting hardware; higher Q_G increases gate drive loss.	Select when higher continuous current (5.5 A) is required and board layout allows isolation for non-isolated tab.
IXTP1R2N60P	600 V, 1.2 A, R_DS(on) = 6.5 Ω, Q_G = 8.5 nC, TO-220	Lower gate charge but significantly higher on-resistance; not suitable for >2 A continuous loads.	Select only for low-current (<1.5 A), ultra-low-Q_G applications where conduction loss is secondary to switching loss.

Compared with STP6NK60ZFP and IXTP1R2N60P, the 2SK3114-S17-AZ offers balanced conduction-switching trade-offs (2.2 Ω / 15 nC) and built-in isolation-critical for simplified thermal design in space-constrained industrial adapters where PCB real estate and assembly cost matter.

FAQ

What is the maximum continuous drain current rating for the 2SK3114-S17-AZ at 25°C case temperature?

The 2SK3114-S17-AZ has a maximum continuous drain current (I_D(DC)) of ±4.0 A at T_C = 25°C. This rating assumes proper heatsinking and is derated linearly above 25°C per the datasheet's derating curve-e.g., ~2.0 A at T_C = 100°C. The 2SK3114-S17-AZ must not exceed this limit to maintain safe channel temperature below 150°C.

Does the 2SK3114-S17-AZ have an integrated gate protection diode?

Yes-the 2SK3114-S17-AZ includes an internal gate-to-source protection diode, as shown in the equivalent circuit diagram. This diode guards against electrostatic discharge (ESD), but Renesas explicitly states that external gate protection remains necessary if transient voltages exceeding ±30 V may occur in the application. The 2SK3114-S17-AZ datasheet confirms this in the "Remark" section on page 7.

Can the 2SK3114-S17-AZ be used in avalanche mode repeatedly?

No-the 2SK3114-S17-AZ is rated for single-pulse avalanche only (E_AS = 10.7 mJ, I_AS = 4.0 A). The datasheet does not specify repetitive avalanche capability, and repeated operation in avalanche risks parametric shift or catastrophic failure. For designs requiring repetitive energy handling, a device with documented repetitive avalanche rating-such as certain STMicroelectronics or Infineon parts-should be selected instead of the 2SK3114-S17-AZ.

What is the typical gate-to-source threshold voltage range for the 2SK3114-S17-AZ?

Per the Electrical Characteristics table, the 2SK3114-S17-AZ has a gate-to-source cutoff voltage (V_GS(off)) range of 2.5 V to 3.5 V, measured at V_DS = 10 V and I_D = 1 mA. This defines the minimum gate voltage needed to reliably turn the device on. The 2SK3114-S17-AZ achieves full enhancement at V_GS ≥ 10 V, where R_DS(on) is guaranteed ≤ 2.2 Ω.

Is the 2SK3114-S17-AZ RoHS compliant?

Yes-the 2SK3114-S17-AZ complies with the EU RoHS Directive. Renesas Electronics confirms environmental compliance in Note 10 of the datasheet, stating users must comply with applicable laws regulating controlled substances, and the company provides environmental data upon request. As a Renesas product manufactured post-2010 (following the NEC/Renesas merger), the 2SK3114-S17-AZ falls under Renesas' standardized RoHS-compliant manufacturing process.
