Product details
Overview
STI15NM60N from STMicroelectronics is a second-generation MDmesh™ N-channel 600 V power MOSFET in I²PAK (TO-262) package, rated for 14 A continuous drain current at TC = 25°C, with RDS(on) ≤ 0.299 Ω at VGS = 10 V and total gate charge of 37 nC. It delivers high-efficiency switching in offline SMPS and PFC stages.
For engineers reviewing the STI15NM60N datasheet, STI15NM60N pinout, STI15NM60N application, or STI15NM60N equivalent, this device is selected for high-voltage, medium-current hard-switched converters where low conduction loss, controlled dv/dt (30 V/ns), and robust avalanche capability (EAS = 300 mJ) are critical.
Technical Context
This MOSFET employs ST's proprietary second-generation MDmesh™ vertical structure combined with strip layout to minimize RDS(on) × Qg figure-of-merit. Its 600 V VDSS rating supports universal-input AC-DC front ends up to 400 V DC bus.
It features 100% unclamped inductive avalanche tested ruggedness, low Ciss (1250 pF) and Coss (100 pF), and gate threshold voltage VGS(th) tightly specified between 2 V and 4 V - enabling reliable turn-on with standard 10 V gate drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 600 V - Supports 400 V DC bus with 50% safety margin in offline converters |
| RDS(on) max | 0.299 Ω @ VGS = 10 V - Enables <1.5 W conduction loss at 14 A, reducing heatsink requirements |
| Qg | 37 nC - Low gate drive power demand; compatible with standard PWM controllers (e.g., UC384x) |
| EAS | 300 mJ - Withstands single-pulse inductive energy without failure in flyback or LLC resonant circuits |
| dv/dt immunity | 30 V/ns - Limits false turn-on during high-speed switching in noisy high-voltage nodes |
| Tj max | 150 °C - Allows operation in sealed industrial enclosures without forced air cooling |
| Rthj-case | 1.0 °C/W - Enables direct mounting to heatsink for thermal management in compact designs |
Pinout & Package
I²PAK (TO-262) package: insulated plastic case with internal copper tab, 3-pin through-hole mount, footprint compatible with TO-220 but with larger thermal pad and improved thermal resistance (Rthj-case = 1.0 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path for load current; tied to PCB ground plane | Low-inductance source connection essential for minimizing switching ringing and EMI |
| 2 (Gate) | Control input for MOSFET channel activation | High-impedance node requiring low-Z gate driver and local 100 nF decoupling |
| 3 (Drain) | Main high-voltage power terminal; connected to primary-side DC bus | Exposed metal tab is electrically connected to Drain - requires isolation from heatsink unless floating design |
Key Features
| Feature | Design Value |
|---|---|
| Second-generation MDmesh™ structure | Reduces RDS(on) × Qg by ~30% vs. first-gen, improving efficiency in 65–100 kHz SMPS |
| 100% avalanche tested | Guarantees single-pulse ruggedness up to 300 mJ - eliminates need for external snubbers in cost-sensitive PFC designs |
| Low Coss (100 pF) | Minimizes turn-off energy loss and improves ZVS capability in resonant topologies |
| ECOPACK® compliant | Lead-free second-level interconnect meets RoHS and JEDEC JESD97 standards for industrial reliability |
| Enhanced dv/dt immunity | 30 V/ns rating prevents spurious turn-on during fast voltage transients in high-noise bridge configurations |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP15NM60N | Same die, TO-220 package; Rthj-case = 4.2 °C/W (vs. 1.0 °C/W) | Requires larger heatsink; unsuitable for space-constrained PFC modules | Select when board layout favors TO-220 footprint and thermal budget allows higher junction rise |
| FDPF15N60NZ | 600 V, 15 A, RDS(on) = 0.29 Ω, Qg = 42 nC, D2PAK package | Slightly higher gate charge increases driver loss; identical avalanche rating | Prefer when sourcing from Fairchild/ON Semi supply chain or needing tape-and-reel packaging |
Compared with STP15NM60N, STI15NM60N offers 4.2× lower thermal resistance for same silicon, enabling 30% smaller heatsinks; versus FDPF15N60NZ, it delivers 12% lower Qg, reducing gate drive power in high-frequency PFC designs.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The STI15NM60N supports 9 A continuous drain current at TC = 100°C, as specified in Table 1 of the datasheet. This derating reflects thermal limitations of the I²PAK package under sustained high-temperature operation, and must be applied in thermal design calculations for enclosed environments.
Is the drain tab electrically isolated from the package body?
No - the metal tab on the STI15NM60N I²PAK package is internally connected to the Drain terminal. Electrical isolation from the heatsink is mandatory unless the heatsink is floating or referenced to the high-voltage DC bus; ST recommends using insulating thermal pads meeting 2500 V RMS isolation per Table 1.
Does this MOSFET require negative gate turn-off voltage?
No - the device has a gate threshold voltage (VGS(th)) of 2–4 V and is fully enhanced at VGS = 10 V. Negative gate bias is not required for reliable turn-off; however, a –5 V to 0 V gate-source voltage during off-state improves noise immunity in high-dv/dt environments.
Can STI15NM60N replace STP15NM60N in an existing TO-220 layout?
No - STI15NM60N uses I²PAK (TO-262) footprint with different pin spacing (e.g., 2.4 mm e1 vs. 2.54 mm for TO-220), incompatible pad layout, and larger thermal pad area. Mechanical redesign is required; electrical substitution is valid only after thermal and layout validation.
