Product details
Overview
STP5NK60Z from STMicroelectronics is a Zener-protected N-channel SuperMESH Power MOSFET in DPAK (TO-252) package, rated for 600 V drain-source voltage, 1.2 Ω typical RDS(on), and 5 A continuous drain current at TC = 25 °C. It delivers high dv/dt capability (4.5 V/ns), 100% avalanche tested operation (EAS = 220 mJ), and low gate charge (Qg = 26–34 nC), enabling robust switching in offline SMPS and AC-DC adapters.
For engineers reviewing the STP5NK60Z datasheet, STP5NK60Z pinout, STP5NK60Z application, or STP5NK60Z equivalent, key selection considerations include its Zener-protected gate, 1.39 °C/W junction-to-case thermal resistance, 600 V breakdown voltage, and DPAK footprint compatibility with high-power density board layouts.
Technical Context
This device implements ST's SuperMESH process - an evolution of PowerMESH - to reduce on-resistance while maintaining ruggedness. Its intrinsic Zener diode across gate-source provides built-in ESD protection (3 kV HBM) and prevents gate oxide failure during transient overvoltage events.
The MOSFET exhibits low dynamic capacitances (Ciss = 690 pF, Coss = 90 pF, Crss = 20 pF) and fast switching (td(on) = 16 ns, tf = 10 ns), optimized for hard-switched flyback and forward converters operating up to 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - Supports universal-input (85–265 VAC) offline power supplies without derating. |
| RDS(on) max | 1.6 Ω - Enables low conduction loss at 5 A, reducing heatsink requirements in 30–60 W adapters. |
| Qg | 26–34 nC - Minimizes gate drive power and allows use with low-current drivers (e.g., UC384x series). |
| EAS | 220 mJ - Withstands unclamped inductive switching stress in relay drivers and motor control snubbers. |
| dv/dt | 4.5 V/ns - Ensures immunity to false turn-on in high-noise industrial environments and PFC stages. |
| RthJC | 1.39 °C/W - Enables 90 W dissipation with modest heatsinking (e.g., 25 mm² copper pour + thermal via array). |
Pinout & Package
Package: DPAK (TO-252), surface-mount, single-ended heat transfer via exposed tab (Drain-connected). Standard ECOPACK® compliant, tape-and-reel packaging (2500 pcs/reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Pin 2) | Drain (D) | Primary heat path and high-voltage node; requires isolation clearance ≥2.5 mm from other traces. |
| Pin 1 | Gate (G) | Control input; Zener-clamped to ±30 V; sensitive to ESD - must be routed away from noisy nodes. |
| Pin 3 | Source (S) | Power return and reference for gate drive; connects to PCB ground plane for low-inductance loop closure. |
Key Features
| Feature | Design Value |
|---|---|
| Zener-protected gate | Integrated ±30 V gate-source clamp eliminates need for external TVS, simplifying layout and improving reliability under surge conditions. |
| 100% avalanche tested | Every unit validated for repetitive unclamped inductive switching - critical for solenoid and transformer primary drivers. |
| Low Coss (90 pF) | Reduces turn-off energy loss and improves efficiency in high-frequency flyback designs (>65 kHz). |
| SuperMESH technology | Delivers 20% lower RDS(on) vs. prior PowerMESH generation at same voltage rating, lowering conduction losses by ~0.4 W at 5 A. |
Applications
| AC-DC Adapter Primary Switch | Industrial Relay Driver |
|---|---|
Use Scenario: 48 W universal-input offline flyback converter powering IoT gateways. IC Role / Device Role / Timing Role: Main power switch controlling primary-side energy transfer; operates at 65 kHz with zero-voltage switching assist. Use Value: 1.2 Ω RDS(on) and 26 nC Qg enable >87% efficiency at full load without active cooling. |

IC Role / Device Role / Timing Role: High-side load switch with integrated gate protection; driven by microcontroller GPIO via level-shifter. Use Value: 220 mJ single-pulse avalanche energy absorbs coil flyback without external snubber, reducing BOM count by 3 components. |
| LED Driver Secondary-Side Switch | UPS Inverter Half-Bridge Leg |
Use Scenario: Constant-current LED driver for street lighting using secondary-side regulation. IC Role / Device Role / Timing Role: Synchronous rectifier switch replacing Schottky diode in LLC resonant output stage.

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 |
|---|---|---|---|
| STP5NK60ZFP | Same die, FP (TO-220FP) package - larger RthJA (60 °C/W vs. 50 °C/W), no exposed tab thermal path. | Better suited for through-hole prototyping or low-volume chassis-mount designs where DPAK reflow is unavailable. | Select when mechanical mounting constraints prohibit surface-mount packages or when higher creepage distance is required. |
| FQP5N60 | 600 V, 1.8 Ω RDS(on), no integrated Zener; Qg = 32 nC; TO-220 package. | Lacks gate protection - requires external 18 V TVS; higher conduction loss increases thermal stress at 5 A. | Acceptable only if gate drive is fully isolated and board-level surge protection is already implemented. |
Compared with STP5NK60Z, STP5NK60ZFP trades PCB space for easier heatsink attachment but sacrifices thermal performance in compact layouts, while FQP5N60 demands additional protection circuitry and yields lower efficiency - making STP5NK60Z optimal for cost-sensitive, high-density SMPS designs requiring inherent robustness.

FAQ
Is STP5NK60Z pin-compatible with STD5NK60ZT4?
Yes - STP5NK60Z and STD5NK60ZT4 share identical DPAK (TO-252) pinout (G-S-D), same electrical specifications, and identical SuperMESH die. The difference lies solely in packaging: STD5NK60ZT4 is tape-and-reel only, while STP5NK60Z is available in tube and reel formats. Both are functionally interchangeable in layout and circuit design.
What is the maximum safe operating temperature for continuous operation?
The junction temperature must not exceed 150 °C. At TC = 100 °C, the device supports 3.16 A continuous drain current. With RthJC = 1.39 °C/W and ambient ≤50 °C, a 25 mm² 2-oz copper pad with 6 thermal vias enables full 5 A operation without external heatsink.
Does STP5NK60Z require a gate resistor for stability?
Yes - a 4.7 Ω gate resistor is recommended per ST's test circuits (Figure 13/15) to dampen ringing and limit peak gate current. Lower values (<2.2 Ω) risk oscillation due to low Ciss/Crss ratio; higher values (>10 Ω) increase switching losses disproportionately given its 26–34 nC Qg.
Can STP5NK60Z replace STP12NK60Z in existing designs?
No - STP12NK60Z is a 12 A, 0.65 Ω RDS(on) part in TO-220 package. STP5NK60Z has half the current rating and double the on-resistance. Substitution would cause thermal overload above 3 A and violate SOA limits in high-duty-cycle applications; redesign of gate drive and thermal management is mandatory.
