STMicroelectronics STW13NK60Z

Overview

STW13NK60Z from STMicroelectronics is a Zener-protected N-channel 600 V SuperMESH Power MOSFET in TO-247 package, delivering 13 A continuous drain current at T_C = 25 °C, 0.48 Ω typical R_DS(on), and 4.5 V/ns peak diode recovery dv/dt capability. It is designed for high-reliability switching applications including offline SMPS, PFC stages, and industrial motor drives where avalanche ruggedness and fast switching are critical.

For engineers reviewing the STW13NK60Z datasheet, STW13NK60Z pinout, STW13NK60Z application, or STW13NK60Z equivalent, key selection criteria include its 100% avalanche-tested rating (E_AS = 400 mJ), gate charge minimization (Q_g = 66–92 nC), Zener-protected gate, and TO-247 thermal performance (R_thJC = 0.83 °C/W).

Technical Context

This device implements ST's SuperMESH technology - an optimized evolution of PowerMESH - to simultaneously reduce on-resistance and enhance dynamic ruggedness. Its structure enables stable operation under high dv/dt stress (4.5 V/ns) and unclamped inductive switching, supported by integrated gate Zener protection against overvoltage transients.

The MOSFET features a robust body diode with t_rr = 570 ns and Q_rr = 4.5 µC at TJ = 150 °C, enabling efficient hard-switched topologies. Its SOA is validated up to 10 A pulsed drain current (I_DM = 52 A) and 2.5 kV RMS insulation withstand voltage between leads and heatsink.

Key Specifications

Pinout & Package

STW13NK60Z uses the TO-247 package - a through-hole, three-terminal power package with isolated metal tab (drain-connected) for direct heatsink mounting and low thermal resistance (R_thJC = 0.83 °C/W). The package supports high-power dissipation (P_TOT = 150 W at T_C = 25 °C) and meets ECOPACK environmental compliance standards.

FAQ

What is the maximum continuous drain current for STW13NK60Z at 100 °C case temperature?

The maximum continuous drain current is 8.2 A at T_C = 100 °C, as specified in Table 1 of DS2636 Rev 8. This derating reflects thermal limits of the TO-247 package and silicon safe operating area; operation above this requires pulse-width limitation or active cooling verification.

Does STW13NK60Z require an external gate resistor for EMI control?

Yes - while the device has low Q_g and fast intrinsic switching, a gate resistor (typically 4.7–22 Ω) is required to dampen ringing, limit peak gate current, and control dV/dt during turn-on/turn-off. The datasheet specifies switching times using R_G = 4.7 Ω in test circuits.

Can STW13NK60Z be used in synchronous rectification topologies?

No - STW13NK60Z is an N-channel enhancement-mode MOSFET with a non-optimized body diode (t_rr = 570 ns, Q_rr = 4.5 µC); it lacks the low Q_rr, fast soft-recovery characteristics required for synchronous rectifier operation. Dedicated SR controllers and logic-level FETs are recommended instead.

Is the metal tab of the TO-247 package internally connected to the drain terminal?

Yes - the metal tab is electrically connected to the drain (pin 2) and serves as the primary thermal path. Electrical isolation from heatsink is mandatory unless the heatsink is referenced to drain potential; ST recommends using insulating pads or ceramic washers when mounting to grounded chassis.
