Product details

Overview

STP3NK60Z from STMicroelectronics is a Zener-protected N-channel SuperMESH™ Power MOSFET in TO-220 package, rated for 600 V drain-source voltage, 3.2 Ω typical R_DS(on), and 2.4 A continuous drain current at T_C = 25 °C. It delivers high dv/dt capability (4.5 V/ns), 100% avalanche tested performance, and integrated gate-source Zener protection - deployed in offline SMPS, AC-DC adapters, and industrial motor control inverters.

For engineers reviewing the STP3NK60Z datasheet, STP3NK60Z pinout, STP3NK60Z application, or STP3NK60Z equivalent, key selection considerations include its 600 V blocking rating, thermal resistance (R_thj-case = 6.25 °C/W), gate charge (Q_g = 11.8 nC), source-drain diode recovery (t_rr = 306 ns), and built-in ±30 V gate-source Zener clamping.

Technical Context

This device implements ST's SuperMESH™ trench-gate process to reduce on-resistance while maintaining ruggedness in high-voltage switching. Its gate structure minimizes Q_g and C_iss (311 pF), enabling fast switching with low drive loss in hard-switched topologies.

The integrated back-to-back gate-source Zener diodes provide ±30 V clamping, eliminating external TVS requirements. Avalanche robustness (E_AS = 150 mJ) and 4.5 V/ns dv/dt immunity support reliable operation under inductive load transients and line surges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Enables direct connection to 400 V DC bus or 230 V AC mains without cascading devices.
R_DS(on) typ.	3.2 Ω - Delivers <1.8 W conduction loss at 2.4 A, supporting thermally constrained TO-220 layouts.
I_D cont. (T_C=25°C)	2.4 A - Sustains full-load current in compact 20–30 W offline converters without derating.
Q_g	11.8 nC - Reduces gate driver power demand and enables use of low-cost bipolar or CMOS drivers.
t_rr	306 ns - Limits reverse recovery loss during hard commutation in flyback and resonant LLC stages.
E_AS	150 mJ - Withstands single-pulse inductive energy without failure, simplifying SOA design in motor drives.
dv/dt immunity	4.5 V/ns - Prevents spurious turn-on during fast voltage transients in high-noise industrial environments.

Pinout & Package

STP3NK60Z uses a standard TO-220 package with isolated tab (drain-connected). The case is electrically connected to the drain terminal, requiring insulating mounting hardware when mounted to a heatsink.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Power return path for drain current	Low-impedance connection to PCB ground plane; carries full load current and must be routed with wide copper.
2 (Gate)	Control electrode for channel conduction	High-impedance input requiring <12 nC charge; sensitive to ESD and noise - needs local RC snubber or ferrite bead.
3 (Drain)	Main high-voltage power terminal	Internally bonded to metal tab; electrically tied to heatsink unless insulated - critical for creepage/clearance compliance.

Key Features

Feature	Design Value
Zener-protected gate	±30 V clamping eliminates need for external gate protection components and improves system-level ESD robustness (2.1 kV HBM).
100% avalanche tested	Guarantees single-pulse ruggedness up to 150 mJ - removes need for external snubbers in inductive switching applications.
Extremely high dv/dt capability	4.5 V/ns rating prevents false triggering during fast voltage transitions in PFC and half-bridge circuits.
Low intrinsic capacitance	C_iss = 311 pF and C_rss = 8 pF reduce Miller effect, enabling stable 100+ kHz switching with minimal gate oscillation.
SuperMESH™ technology	Optimized trench geometry achieves 3.2 Ω R_DS(on) at 600 V - 25% lower than prior PowerMESH™ generation for same die size.

Applications

AC-DC Adapter Primary Switch

Industrial Motor Control Inverter

Use Scenario: 24 W universal-input offline flyback converter operating at 65 kHz.

IC Role / Device Role / Timing Role: Main power switch handling 600 V DC link, modulated by PWM controller (e.g., VIPer06).

Use Value: Low Q_g (11.8 nC) reduces gate driver losses; Zener protection avoids external clamp diodes, cutting BOM cost by $0.08/unit.

Use Scenario: 3-phase inverter stage driving 1/4 HP BLDC motor in HVAC fan module.

IC Role / Device Role / Timing Role: High-side switch in IGBT/MOSFET half-bridge, switching at ≤20 kHz with 120° commutation.

Use Value: 150 mJ E_AS withstands inductive kickback without desaturation detection; 4.5 V/ns dv/dt rating ensures noise immunity in EMI-heavy factory environments.

LED Driver Secondary Side Switch

UPS Inverter Output Stage

Use Scenario: Isolated buck-boost LED driver for street lighting (72 V output, 1.2 A).

IC Role / Device Role / Timing Role: Synchronous rectifier replacement in secondary-side active clamp topology.

Use Value: Low R_DS(on) (3.2 Ω) cuts conduction loss vs. Schottky diode; integrated Zener allows direct gate drive from transformer winding without bias supply.

Use Scenario: Line-interactive UPS delivering 600 VA with pure sine-wave inverter output.

IC Role / Device Role / Timing Role: Low-side switch in full-bridge output stage, switching at 20 kHz with dead-time control.

Use Value: 2.4 A I_D rating supports peak surge currents up to 9.6 A (IDM); TO-220 package enables direct heatsink mounting for thermal stability during extended battery backup.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP3NK60ZFP	Same die, TO-220FP package with shorter leads and reduced height; R_thj-case = 2.78 °C/W (vs. 6.25 °C/W).	Better thermal performance in space-constrained designs but requires different mounting hardware and footprint.	Select when board height is limited and heatsink interface area permits FP-style clip mounting.
STD3NK60ZT4	DPAK package; identical electrical specs but R_thj-case = 2.78 °C/W and lower I_D derating above 70 °C ambient.	Suitable for surface-mount automated assembly; not recommended for >1.5 A continuous loads without large copper pour.	Choose for reflow-compatible designs where manual TO-220 insertion is undesirable and thermal budget allows.

Compared with STP3NK60Z, STP3NK60ZFP offers superior thermal resistance but demands revised mechanical layout, while STD3NK60ZT4 enables SMT production at the cost of reduced power handling margin in sealed enclosures.

FAQ

Is STP3NK60Z RoHS-compliant and halogen-free?

Yes. STP3NK60Z is manufactured in STMicroelectronics' ECOPACK®-compliant TO-220 package, meeting RoHS Directive 2011/65/EU and IEC 61249-2-21:2011 for halogen-free materials. Full compliance documentation is available via ST's quality portal using order code STP3NK60Z.

What is the maximum safe operating temperature for continuous operation?

The absolute maximum junction temperature is 150 °C. For continuous operation at full 2.4 A drain current, case temperature must remain ≤100 °C per datasheet derating curves. With R_thj-case = 6.25 °C/W, this requires a heatsink thermal resistance of ≤26 °C/W at 25 °C ambient.

Can STP3NK60Z replace STP4NK60Z in existing designs?

No - STP4NK60Z has 2.4 Ω typical R_DS(on) and 4 A I_D, while STP3NK60Z is rated at 3.2 Ω and 2.4 A. Substitution would increase conduction loss by ~33% and reduce current headroom; thermal validation and SOA re-analysis are required before any change.

Does the built-in Zener protect against both positive and negative gate transients?

Yes. The integrated back-to-back Zener diodes provide symmetrical ±30 V clamping between gate and source, protecting against both positive overvoltage (e.g., Miller spike) and negative transients (e.g., shoot-through induced reverse bias), verified per JEDEC JESD22-A114F HBM testing.
