STMicroelectronics STF16NK60Z

Overview

STF16NK60Z from STMicroelectronics is an N-channel 600 V, 0.38 Ω (typ), 14 A (T_C = 25 °C), TO-220FP-packaged SuperMESH™ Power MOSFET with integrated gate-source Zener protection (±30 V), 100% avalanche tested, and rated for 40 W total dissipation. It serves as a high-voltage switching device in offline SMPS, PFC stages, and industrial motor drives where robust dv/dt immunity and low gate charge are critical.

For engineers reviewing the STF16NK60Z datasheet, STF16NK60Z pinout, STF16NK60Z application, or STF16NK60Z equivalent, key selection criteria include its 4.5 V/ns peak diode recovery dv/dt capability, 86 nC total gate charge, 158 pF equivalent output capacitance, 360 mJ single-pulse avalanche energy, and thermal resistance of 3.1 °C/W (junction-to-case).

Technical Context

This MOSFET employs ST's SuperMESH™ strip-based layout to achieve significantly lower R_DS(on) versus prior PowerMESH™ generations while maintaining superior ruggedness. Its built-in back-to-back gate-source Zener diodes (BVGSO = 30 V) eliminate need for external ESD clamps and suppress transient-induced gate overvoltage.

The device is optimized for hard-switched topologies operating up to 100 kHz, with low C_iss (2650 pF), C_oss (285 pF), and C_rss (62 pF) enabling fast switching and reduced switching losses. Safe operating area (SOA) is defined for pulse widths down to 10 µs and supports repetitive avalanche operation at I_AR = 14 A.

FAQ

What is the maximum continuous drain current for STF16NK60Z at 100 °C case temperature?

The maximum continuous drain current is 8.8 A at T_C = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limits of the TO-220FP package, not silicon capability-conduction remains safe up to 14 A only when case temperature is maintained at ≤25 °C.

Does STF16NK60Z require an external gate resistor for stability?

A gate resistor is required for controlled turn-on/turn-off timing and to dampen ringing, but value depends on drive strength and layout. Typical values range from 4.7 Ω to 22 Ω; 4.7 Ω was used in the datasheet's switching time test (Figure 18) to achieve t_r = 25 ns and t_f = 15 ns under defined conditions.

Can STF16NK60Z be used in synchronous rectification applications?

No-it is an N-channel high-side switch optimized for unidirectional conduction and avalanche energy absorption, not bidirectional body-diode conduction. Its source-drain diode has t_rr = 490 ns and Q_rr = 5.4 nC at 25 °C, making it unsuitable for high-frequency synchronous rectification where low reverse recovery is mandatory.

Is STF16NK60Z compliant with RoHS and REACH regulations?

Yes-STF16NK60Z is manufactured in ECOPACK®-compliant TO-220FP packaging, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including material declarations, is available via ST's official product page and ECOPACK® portal at www.st.com.
