Product details

Overview

2SK1526-E from Renesas Electronics is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and switching regulators. It features a 450 V drain-to-source breakdown voltage, 40 A continuous drain current, and a low 0.11–0.15 Ω R_DS(on) at V_GS = 10 V, enabling efficient high-power operation in industrial power supplies.

For engineers reviewing the 2SK1526-E datasheet, 2SK1526-E pinout, 2SK1526-E application, or 2SK1526-E equivalent, this device is selected for its robust safe operating area, fast switching (t_d(on) = 60 ns, t_f = 160 ns), and integrated body diode with 600 ns reverse recovery time - critical parameters for hard-switched SMPS designs requiring thermal stability and low conduction loss.

Technical Context

This MOSFET employs a planar vertical structure optimized for high-voltage, high-current switching with no secondary breakdown limitation. Its gate threshold voltage (V_GS(off) = 2.0–3.0 V) ensures reliable turn-on under standard 10 V gate drive while maintaining low gate leakage (±10 µA at ±25 V).

The device integrates a fast-recovery body diode (V_DF = 1.2 V at 40 A, t_rr = 600 ns) and exhibits low output capacitance (C_oss = 1430 pF) and reverse transfer capacitance (C_rss = 150 pF), supporting high-frequency operation up to several hundred kHz in resonant and hard-switched topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	450 V - Supports input voltages up to 360 V DC in offline or high-bus industrial SMPS without derating.
R_DS(on)	0.11–0.15 Ω @ V_GS = 10 V - Enables ≤1.2 W conduction loss at 40 A, reducing heatsink requirements.
I_D	40 A continuous - Rated for sustained high-current output stages in 500–1000 W power converters.
t_d(on)/t_f	60 ns / 160 ns - Minimizes switching transition losses in 100–300 kHz hard-switched applications.
C_iss/C_rss	5800 pF / 150 pF - Low Miller charge improves gate drive efficiency and reduces EMI susceptibility.
T_ch	150 °C - Allows operation in high-ambient environments (e.g., enclosed industrial enclosures) with proper thermal design.

Pinout & Package

2SK1526-E is housed in the TO-3PL package (RENESAS code PRSS0004ZF-A), a through-hole, isolated-tab metal can with 3 terminals and 9.9 g mass. The case serves as the drain connection and must be electrically isolated from heatsink unless referenced to system ground.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Receives 10 V logic-level gate drive; low input capacitance (C_iss = 5800 pF) enables simple driver stage design.
2 (Drain)	Main current output path	Connected to internal die backside; electrically tied to metal tab - requires insulating washer when mounted to grounded heatsink.
3 (Source)	Reference node for gate drive	Serves as return path for load current and gate drive loop; low-inductance PCB layout essential for stable high-speed switching.

Key Features

Feature	Design Value
No secondary breakdown	Enables safe linear-mode operation and eliminates need for SOA derating in transient overload conditions.
Low R_DS(on) × Q_g product	Combines low conduction loss with fast switching - verified by 60 ns turn-on delay and 175 ns rise time at 20 A.
Integrated fast body diode	V_DF = 1.2 V / t_rr = 600 ns supports synchronous rectification or freewheeling in buck/forward converters.
High V_GSS rating	±30 V gate tolerance prevents damage during gate drive transients or layout-induced ringing.

FAQ

What is the maximum continuous drain current rating for the 2SK1526-E?

The 2SK1526-E is rated for 40 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 power vs. temperature derating curve - at 100°C case temperature, the usable I_D drops to approximately 22 A. Always verify thermal design using the specified θ_ch–c = 0.5°C/W value and actual board-level thermal resistance.

Does the 2SK1526-E have an integrated body diode, and what are its key characteristics?

Yes, the 2SK1526-E includes an integrated body diode with a forward voltage (V_DF) of 1.2 V at 40 A and a reverse recovery time (t_rr) of 600 ns under specified test conditions (I_F = 40 A, di_F/dt = 100 A/µs). This diode is fully characterized and suitable for freewheeling in buck, forward, and LLC topologies - unlike many discrete MOSFETs where body diode performance is unspecified or marginal.

What is the gate threshold voltage range for the 2SK1526-E, and how does it affect drive requirements?

The 2SK1526-E has a gate-to-source cutoff voltage (V_GS(off)) of 2.0–3.0 V at I_D = 1 mA. This ensures full enhancement at standard 10 V gate drive while allowing compatibility with 5 V logic-level drivers in low-power configurations. Gate leakage remains below ±10 µA at ±25 V, minimizing static power draw in always-on control circuits using the 2SK1526-E.

Can the 2SK1526-E be used in avalanche-rated applications?

No - the 2SK1526-E datasheet does not specify single-pulse or repetitive avalanche energy ratings (E_AS). Its Absolute Maximum Ratings define only V_DSS, I_D, and P_ch; operation beyond V_DSS is not guaranteed. For avalanche-tolerant designs, select devices explicitly rated for unclamped inductive switching (UIS), such as certain ON Semiconductor or Infineon automotive-grade MOSFETs.

What is the recommended PCB layout practice for the 2SK1526-E's TO-3PL package?

For the 2SK1526-E in TO-3PL, use wide copper pours on both top and inner layers for source and drain connections, with multiple thermal vias under the tab to internal ground or power planes. Keep gate traces short and shielded from drain switching noise; place the gate resistor (typically 10–47 Ω) as close as possible to the gate pin. Mount the device with insulating hardware if the heatsink is grounded, referencing the 2SK1526-E's isolated-tab construction.
