Product details

Overview

TK7Q60W,S1VQ from Toshiba is a silicon N-channel MOSFET using Super Junction DTMOS™ structure, designed as a high-voltage switching element in offline power supplies. It delivers 600 V V_DSS, 7.0 A continuous drain current, and low R_DS(ON) of 0.5 Ω (typ.) at V_GS = 10 V, enabling efficient operation in AC-DC adapters and industrial SMPS.

For engineers reviewing the TK7Q60W,S1VQ datasheet, TK7Q60W,S1VQ pinout, TK7Q60W,S1VQ application, or TK7Q60W,S1VQ equivalent, key selection criteria include avalanche ruggedness (E_AS = 92 mJ), diode reverse recovery performance (t_rr = 230 ns), thermal resistance (R_th(ch-c) = 2.09 °C/W), and gate charge (Q_g = 15 nC) for optimized hard-switching efficiency.

Technical Context

This device implements Toshiba's DTMOS™ (Double-diffused Trench MOS) architecture to achieve low on-resistance and fast switching with controlled dv/dt ruggedness (≥25 V/ns). Its enhancement-mode threshold voltage (2.7–3.7 V) ensures reliable gate drive compatibility with standard 5 V and 15 V controllers.

The integrated body diode supports synchronous rectification and flyback operation, with characterized Q_rr = 1.7 µC and I_rr = 16 A, enabling predictable snubber design in quasi-resonant converters. Thermal design is anchored by a low channel-to-case resistance and IPAK package heatsink-integrated drain terminal.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - Supports universal-input (85–265 VAC) offline topologies without derating
R_DS(ON)	0.5 Ω (typ.) at V_GS = 10 V - Reduces conduction loss in 7 A continuous applications
I_D (DC)	7.0 A - Enables compact designs for <100 W SMPS with minimal heatsinking
E_AS	92 mJ - Withstands single-pulse inductive energy in clamp circuits and PFC stages
t_rr	230 ns - Limits diode recovery loss and EMI in high-frequency flyback converters
Q_g	15 nC - Balances switching speed and gate driver stress in 65–130 kHz operation
R_th(ch-c)	2.09 °C/W - Allows direct mounting to PCB copper pour or heatsink for thermal management

Pinout & Package

TK7Q60W,S1VQ is housed in an IPAK (TOSHIBA 2-7L1A) surface-mount package with integral heatsink tab on the drain terminal. The package weighs 0.337 g and features three external terminals: Gate (pin 1), Drain/Heatsink (pin 2), Source (pin 3).

Pin/Terminal	Circuit Role	Design Meaning
1: Gate	Control input	Receives PWM signal; threshold voltage 2.7–3.7 V enables direct drive from UC384x or similar controllers
2: Drain (Heatsink)	High-side power node	Exposed metal pad serves as both drain connection and primary thermal path to PCB/heatsink
3: Source	Power return / reference	Common node for gate drive return and current sensing; connects to ground plane or shunt resistor

Key Features

Feature	Design Value
DTMOS™ Super Junction Structure	Enables 0.5 Ω R_DS(ON) at 600 V while maintaining fast switching and low C_oss (13 pF)
Low Q_gd/Q_g ratio	Q_gd = 8.0 nC of total Q_g = 15 nC - Improves Miller immunity and hard-switching robustness
Body diode with soft recovery	t_rr = 230 ns, Q_rr = 1.7 µC - Reduces voltage overshoot and EMI during turn-off
Avalanche-rated operation	E_AS = 92 mJ (T_ch = 25 °C) - Supports unclamped inductive switching in PFC and resonant converters
ESD-sensitive handling	Class 1B per JESD22-A114 - Requires grounded workstations and anti-static packaging during assembly

FAQ

What is the maximum continuous drain current rating for TK7Q60W,S1VQ?

The TK7Q60W,S1VQ has a maximum continuous drain current (I_D) of 7.0 A at T_c = 25 °C. This rating assumes proper heatsinking via the drain-connected metal tab. At higher case temperatures or without forced cooling, derating is required per the Safe Operating Area curve in the datasheet. For sustained 7 A operation, thermal design must maintain channel temperature ≤150 °C.

Does TK7Q60W,S1VQ have a guaranteed avalanche rating?

Yes, TK7Q60W,S1VQ is fully specified for single-pulse avalanche energy (E_AS) at 92 mJ with T_ch = 25 °C, V_DD = 90 V, L = 49.9 mH, R_G = 25 Ω, and I_AR = 1.8 A. This rating is guaranteed per datasheet Rev. 2.0 and enables use in unclamped inductive switching applications such as PFC boost stages and flyback snubbers without external protection.

What is the gate threshold voltage range for TK7Q60W,S1VQ?

The gate threshold voltage (V_th) for TK7Q60W,S1VQ is specified from 2.7 V to 3.7 V at V_DS = 10 V and I_D = 0.35 mA. This enhancement-mode range ensures reliable turn-on with standard 5 V logic-level drivers and compatibility with UC384x, TL494, and other PWM controllers without level-shifting circuitry.

Can TK7Q60W,S1VQ be used in place of a TO-220 MOSFET in existing designs?

TK7Q60W,S1VQ uses an IPAK (2-7L1A) surface-mount package, not TO-220. While electrical specs align closely with many TO-220 600 V MOSFETs, direct replacement requires PCB layout revision due to different footprint, thermal pad placement, and soldering profile. Its drain-connected heatsink tab must be soldered to a large copper area for thermal performance equivalent to TO-220 mounting.

What is the typical reverse recovery time of the body diode in TK7Q60W,S1VQ?

The typical reverse recovery time (t_rr) of the integrated body diode in TK7Q60W,S1VQ is 230 ns under test conditions of I_DR = 3.5 A, V_GS = 0 V, and –dI_DR/dt = 100 A/µs. This soft-recovery characteristic helps reduce switching noise and voltage overshoot in flyback and LLC resonant converters where the body diode conducts during dead-time intervals.
