Product details

Overview

TK10V60W from Toshiba Electronic Devices & Storage Corporation is a silicon N-channel super-junction MOSFET designed for high-voltage switching in offline power supplies. It features 600 V V_DSS, 9.7 A continuous drain current, 0.327 Ω typical R_DS(ON) at V_GS = 10 V, and DFN8x8 surface-mount packaging with integrated heatsink drain. It is used in AC-DC adapters and industrial switching regulators.

For engineers reviewing the TK10V60W datasheet, TK10V60W pinout, TK10V60W application, or TK10V60W equivalent, key selection criteria include avalanche energy rating (74.5 mJ), channel-to-case thermal resistance (1.5 °C/W), gate threshold voltage range (2.7–3.7 V), and diode reverse recovery characteristics (t_rr = 250 ns, Q_rr = 2.2 µC).

Technical Context

This device implements Toshiba's DTMOS™ IV super-junction architecture to achieve low conduction loss while maintaining fast switching and robust dv/dt ruggedness (≥50 V/ns). Its dual-source configuration (Source1 for gate return, Source2 for main current) enables precise control of gate loop inductance and minimizes source inductance effects during hard-switching.

The TK10V60W integrates an intrinsic body diode with characterized reverse recovery behavior (I_rr = 19 A, t_rr = 250 ns) and supports unclamped inductive switching with guaranteed single-pulse avalanche energy of 74.5 mJ at T_ch = 25 °C - critical for flyback and resonant converter reliability.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	600 V - supports universal-input offline SMPS designs up to 400 V DC bus with margin.
R_DS(ON) (typ.)	0.327 Ω at V_GS = 10 V - reduces conduction loss in 10–15 W high-efficiency adapters.
I_D (DC)	9.7 A at T_c = 25 °C - enables compact thermal design when mounted on 2-layer PCB with copper pour.
E_AS	74.5 mJ - ensures reliable operation under inductive load switching without external snubbers.
R_th(ch-c)	1.5 °C/W - allows direct thermal coupling to heatsink via exposed drain pad for >80 W dissipation capability.
t_rr	250 ns - limits diode commutation loss in quasi-resonant and ZVS topologies.
Q_gd	9.5 nC - balances switching speed and EMI control in 65–100 kHz flyback converters.

Pinout & Package

Package: DFN8x8 (TOSHIBA designation 2-8T1A), 8 mm × 8 mm × 0.85 mm, thermally enhanced with exposed drain pad (Pin 5) acting as primary heatsink interface. Weight: 0.175 g (typ.).

Pin/Terminal	Circuit Role	Design Meaning
1	Gate	Control input; requires low-inductance routing to minimize ringing and ensure stable turn-on/turn-off.
2	Source1	Gate driver return path; must be connected directly to driver ground to avoid gate loop instability.
3, 4	Source2	Main current return; carries full load current - routed with wide copper traces and multiple vias to ground plane.
5	Drain (Heatsink)	High-voltage output node and thermal interface; soldered to large copper area for thermal management.

Key Features

Feature	Design Value
Super-junction DTMOS™ IV structure	Enables 600 V rating with R_DS(ON) < 0.38 Ω - improves power density vs. planar MOSFETs in same package.
Dual-source terminal layout	Separates gate return (Source1) from power return (Source2) - suppresses common-source inductance and improves switching stability.
Guaranteed avalanche capability	74.5 mJ single-pulse E_AS - eliminates need for external clamping in cost-sensitive flyback designs.
Body diode with controlled Q_rr	Q_rr = 2.2 µC and t_rr = 250 ns - reduces diode-induced switching loss and EMI in QR/ZVS converters.
dv/dt ruggedness	≥50 V/ns - prevents false turn-on during high dV/dt transients in bridge-leg or half-bridge configurations.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP10NK60ZFP	600 V, 10 A, R_DS(ON) = 0.65 Ω (typ.), TO-220FP package, no guaranteed E_AS spec.	Requires external heatsink and avalanche snubber; higher conduction loss increases thermal footprint.	Preferred where through-hole assembly and legacy board compatibility are required.

FAQ

What is the maximum continuous drain current rating for TK10V60W?

The TK10V60W has a maximum continuous drain current (I_D) of 9.7 A at case temperature T_c = 25 °C. This rating assumes proper PCB thermal design with adequate copper area under the exposed drain pad. At higher case temperatures, the current must be derated per the Safe Operating Area curve in the TK10V60W datasheet - for example, to ~6.5 A at T_c = 100 °C.

Does TK10V60W have a specified avalanche energy rating?

Yes, the TK10V60W specifies a guaranteed single-pulse avalanche energy (E_AS) of 74.5 mJ under test conditions of V_DD = 90 V, T_ch = 25 °C (initial), L = 20.9 mH, R_G = 25 Ω, and I_AR = 2.5 A. This rating is validated and guaranteed per Toshiba's production testing protocol, enabling robust unclamped inductive switching in flyback and forward converters.

How should the dual-source pins (2, 3, 4) of TK10V60W be connected in layout?

Pin 2 (Source1) must be used exclusively as the gate driver return path and tied directly to the driver IC ground with minimal trace length. Pins 3 and 4 (Source2) carry the full load current and must be connected to the main power ground plane using wide copper traces and multiple thermal vias. Separating these paths prevents gate loop instability and reduces switching overshoot in the TK10V60W.

What is the gate threshold voltage range for TK10V60W?

The TK10V60W has a gate threshold voltage (V_th) range of 2.7 V to 3.7 V, measured at V_DS = 10 V and I_D = 0.5 mA. This enhancement-mode characteristic ensures reliable turn-off at logic-level gate drive voltages and supports compatibility with standard 3.3 V or 5 V PWM controllers without level-shifting circuitry in the TK10V60W application.

Is TK10V60W suitable for use in quasi-resonant (QR) flyback converters?

Yes, the TK10V60W is well-suited for QR flyback converters due to its characterized reverse recovery time (t_rr = 250 ns) and charge (Q_rr = 2.2 µC), low Q_gd (9.5 nC), and ≥50 V/ns dv/dt ruggedness. These parameters enable clean valley switching, reduced diode stress, and stable operation across line and load variations in the TK10V60W-based QR design.
