Product details

Overview

2SK3116(1)-ZK-E2-AZ from Renesas Electronics is an N-channel enhancement-mode DMOS power MOSFET designed for high-voltage switching applications including AC adapters and offline SMPS. It features 600 V V_DSS, 1.2 Ω max R_DS(on) at V_GS = 10 V and I_D = 3.75 A, 26 nC typical total gate charge, avalanche-rated (E_AS = 37.5 mJ), and TO-220AB package with isolated drain tab.

For engineers reviewing the 2SK3116(1)-ZK-E2-AZ datasheet, 2SK3116(1)-ZK-E2-AZ pinout, 2SK3116(1)-ZK-E2-AZ application, or 2SK3116(1)-ZK-E2-AZ equivalent, key selection criteria include its 600 V blocking capability, low Q_G/R_DS(on) ratio for hard-switched converters, body diode recovery performance (t_rr = 1.6 µs), and thermal resistance (R_th(ch–C) = 1.79 °C/W) in TO-220AB mounting.

Technical Context

This device operates as a unidirectional high-side or low-side switch in flyback, forward, and resonant converter topologies. Its gate threshold voltage (V_GS(off) = 2.5–3.5 V) enables standard 10 V gate drive compatibility, while its low C_iss (1100 pF) and Crss (20 pF) support fast switching with minimal Miller-induced oscillation risk.

The integrated body diode exhibits 1.0 V forward voltage at 7.5 A and controlled reverse recovery (Q_rr = 7.6 µC, di/dt = 50 A/µs), making it suitable for non-synchronous rectification where diode conduction occurs during dead time. Avalanche ruggedness is validated under single-pulse inductive load conditions (I_AS = 7.5 A, E_AS = 37.5 mJ).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - supports 400 VAC input designs with ≥2× safety margin against line transients
R_DS(on) max	1.2 Ω @ V_GS = 10 V, I_D = 3.75 A - determines conduction loss in continuous-current operation
Q_G typ	26 nC @ V_DD = 450 V - sets gate driver current requirement and switching loss trade-off
E_AS	37.5 mJ - enables robust operation under inductive turn-off stress without external snubbers
t_rr	1.6 µs @ I_F = 7.5 A - defines minimum dead time needed to avoid shoot-through in half-bridge configurations
R_th(ch–C)	1.79 °C/W - allows 70 W dissipation at T_C = 25 °C, critical for heatsink sizing
I_D(DC)	±7.5 A - maximum continuous drain current limited by package thermal capacity

Pinout & Package

2SK3116(1)-ZK-E2-AZ is housed in a TO-220AB (MP-25) package with electrically isolated drain tab (pin 2 and pin 4 share drain connection). The case serves as the drain terminal and must be mounted to a heatsink with appropriate insulation when used in high-side configurations.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control electrode	Receives 10 V logic-level drive; ±30 V absolute max rating prevents gate oxide damage
2 (Drain)	Main current output	Connected to high-voltage rail; tab (pin 4) is same node - requires isolation in PCB layout
3 (Source)	Reference and return path	Serves as local ground reference for gate drive; carries full load current and diode reverse recovery current
4 (Fin/Drain)	Thermal and electrical drain extension	Electrically identical to pin 2; provides mechanical interface for heatsink attachment

Key Features

Feature	Design Value
Low gate charge	26 nC typical enables efficient 100–300 kHz switching with <1 W gate driver loss
Avalanche energy rating	37.5 mJ validated single-pulse withstand ensures reliability in unclamped inductive switching
Body diode softness	Controlled reverse recovery (Q_rr = 7.6 µC) reduces EMI and voltage overshoot during freewheeling
High V_DSS / R_DS(on) ratio	600 V breakdown with 1.2 Ω on-resistance balances voltage margin and conduction efficiency
TO-220AB thermal performance	R_th(ch–C) = 1.79 °C/W supports 70 W continuous dissipation with modest heatsinking

FAQ

What is the maximum continuous drain current rating for the 2SK3116(1)-ZK-E2-AZ?

The 2SK3116(1)-ZK-E2-AZ has a maximum continuous drain current (I_D(DC)) of ±7.5 A at T_A = 25 °C. This rating assumes adequate heatsinking and is derated linearly above 25 °C ambient per the datasheet's derating curve. At case temperature T_C = 25 °C, the device supports 70 W dissipation, enabling higher current in thermally optimized layouts.

Does the 2SK3116(1)-ZK-E2-AZ have avalanche capability, and how is it specified?

Yes, the 2SK3116(1)-ZK-E2-AZ is fully rated for single-pulse avalanche operation with I_AS = 7.5 A and E_AS = 37.5 mJ under defined test conditions (V_DD = 150 V, R_G = 25 Ω, starting T_ch = 25 °C). This ruggedness allows safe operation during inductive turn-off events without external clamping components in properly designed flyback or forward converters.

What is the gate threshold voltage range for the 2SK3116(1)-ZK-E2-AZ, and why does it matter?

The gate threshold voltage (V_GS(off)) for the 2SK3116(1)-ZK-E2-AZ is specified as 2.5–3.5 V at V_DS = 10 V and I_D = 1 mA. This range ensures reliable turn-on with standard 10 V gate drivers while preventing accidental conduction from noise or leakage currents below 2.5 V - critical for stable operation in high-noise industrial power environments.

Can the 2SK3116(1)-ZK-E2-AZ be used in synchronous rectification topologies?

No, the 2SK3116(1)-ZK-E2-AZ is not recommended for synchronous rectification due to its relatively slow body diode recovery (t_rr = 1.6 µs) and lack of optimized reverse recovery characteristics. Its design targets primary-side switching where the body diode conducts only during brief dead-time intervals, not continuous forward conduction like secondary-side SR FETs.

What package type does the 2SK3116(1)-ZK-E2-AZ use, and is the drain electrically isolated?

The 2SK3116(1)-ZK-E2-AZ uses the TO-220AB (MP-25) package with pins 2 (Drain) and 4 (Fin/Drain) electrically connected and isolated from the source and gate terminals. This isolation allows direct mounting to a grounded heatsink without additional insulation when used in low-side configurations, or with insulating pads in high-side applications.
