Product details
Overview
STB23NM60ND from STMicroelectronics is a 600 V, 23 A, N-channel SuperMESH™ III power MOSFET in TO-220FP package, featuring 190 mΩ RDS(on) at VGS = 10 V, 45 nC total gate charge, and 100% avalanche-rated ruggedness for hard-switching applications in offline SMPS and motor drives.
For engineers reviewing the STB23NM60ND datasheet, STB23NM60ND pinout, STB23NM60ND application, or STB23NM60ND equivalent, this device is selected for high-voltage DC-DC converters requiring low conduction loss, fast switching with controlled EMI, and robust unclamped inductive switching capability under full load conditions.
Technical Context
This MOSFET employs ST's SuperMESH™ III process to achieve optimized trade-offs between RDS(on), Qg, and Eoss, enabling efficient operation in continuous conduction mode (CCM) PFC stages and resonant LLC primary switches. Its 600 V VDSS rating supports universal AC input (85–265 VAC) designs without derating.
The device features an integrated ultra-fast recovery body diode (trr = 75 ns, Qrr = 120 nC), enabling ZVS-capable topologies and reducing snubber losses in flyback and half-bridge configurations where reverse recovery behavior critically impacts efficiency and thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 600 V - Supports universal offline input with ≥20% voltage margin over peak rectified 375 V. |
| RDS(on) max | 190 mΩ @ VGS = 10 V - Enables <1.5 W conduction loss at 23 A DC, suitable for 250–500 W power stages. |
| Qg | 45 nC - Allows gate drive with standard 1-A peak drivers at 100 kHz without excessive Miller plateau time. |
| Eoss | 120 nJ @ 400 V - Reduces turn-on switching loss in hard-switched topologies; enables >90% efficiency in 300 W adapters. |
| trr | 75 ns - Limits diode reverse recovery current spike, easing EMI filter design in high-frequency flyback converters. |
| PD (Tc = 25°C) | 30 W - Requires heatsink for sustained 23 A operation; thermal resistance RthJC = 0.83 °C/W enables compact thermal layout. |
Pinout & Package
TO-220FP (Full-Pak) package: insulated backside, vertical mounting, no heatsink isolation required; 3-pin through-hole configuration with drain tab electrically connected to pin 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Power return path for channel current | Low-inductance source connection; ties directly to PCB ground plane for stable switching node control. |
| Pin 2 (Drain) | Main high-side power terminal | Internally bonded to metal tab; must be connected to high-voltage bus or transformer primary; provides mechanical anchoring. |
| Pin 3 (Gate) | Control electrode for channel modulation | High-impedance input requiring <100 pF layout capacitance; sensitive to ringing-requires local RC snubber if driving >50 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| 100% Avalanche Tested | Guarantees reliable operation under unclamped inductive switching up to IAR = 23 A, eliminating need for external clamping circuits in relay drivers. |
| Ultra-Low Qg/RDS(on) Ratio | 235 nC·Ω - Improves figure-of-merit for high-frequency SMPS, reducing combined conduction + switching loss by ~18% vs. legacy 600 V MOSFETs. |
| Fast Body Diode (trr = 75 ns) | Enables quasi-resonant flyback operation without external Schottky catch diode, cutting BOM count and footprint in compact AC/DC adapters. |
| Enhanced dV/dt Immunity | Rated for 4.5 V/ns - Prevents spurious turn-on during high dv/dt transients in bridge-leg configurations, improving system reliability without gate resistors >10 Ω. |
Applications
| Industrial Motor Drives | Server PSU Primary Switch |
|---|---|
Use Scenario: 3-phase inverter stage for 0.75 kW BLDC pumps operating from 380 V AC mains. IC Role / Device Role / Timing Role: High-side switching element in six-step commutation; handles 23 A peak phase current with 100 kHz PWM. Use Value: Low RDS(on) minimizes thermal rise in enclosed enclosures; avalanche rating eliminates need for freewheeling diode snubbers. | Use Scenario: Active clamp forward converter in 80 PLUS Titanium 1.2 kW server power supply. IC Role / Device Role / Timing Role: Main switch controlling energy transfer from primary winding; operates at 250 kHz with zero-voltage switching assist. Use Value: Fast body diode enables clean active clamp reset; low Eoss reduces turn-on loss during ZVS transition. |
| LED Streetlight Driver | EV Onboard Charger (OBC) PFC Stage |
Use Scenario: Constant-current buck-boost LED driver for 150 W outdoor luminaires with wide input range (100–305 V AC). IC Role / Device Role / Timing Role: Synchronous rectifier and main switch in hybrid topology; conducts 18 A RMS with 120 Hz ripple superimposed on 50 kHz switching. Use Value: Rugged body diode withstands line dips and surges; TO-220FP insulation allows direct heatsink mounting without insulator pads. | Use Scenario: Boost PFC switch in 6.6 kW bidirectional OBC handling both AC/DC and DC/AC modes. IC Role / Device Role / Timing Role: Critical conduction mode (CrM) boost switch operating up to 200 kHz with variable frequency sweep. Use Value: Low Qg ensures stable gate drive across full load range; 600 V rating covers worst-case DC link voltage (450 V) with safety margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPP60R190C7 | RDS(on) = 190 mΩ, but higher Qg (52 nC); CoolMOS™ C7 process offers lower Eoss (95 nJ). | Better suited for ZVS-heavy LLC resonant converters; less optimal for CrM PFC due to higher gate drive loss. | Select when Eoss-driven efficiency dominates over Qg-related drive complexity. |
| IRFP4668PBF | Higher RDS(on) (220 mΩ), larger Qg (62 nC); no avalanche rating specified in datasheet. | Limited to non-critical industrial supplies where surge immunity is managed externally. | Choose only if cost sensitivity outweighs reliability requirements and thermal margin is ample. |
Compared with IPP60R190C7 and IRFP4668PBF, STB23NM60ND delivers superior balance of avalanche ruggedness, gate drive simplicity, and body diode performance-making it preferred for cost-constrained, high-reliability offline converters where layout space limits snubber components.

FAQ
What is the maximum junction temperature for continuous operation?
The STB23NM60ND has a rated maximum junction temperature (Tj) of 150°C. Continuous operation at this limit requires thermal design ensuring RthJA ≤ 2.78 °C/W under natural convection, or use of a heatsink achieving RthJC + RthCS + RthSA ≤ 0.83 °C/W. Derating is mandatory above 125°C ambient.
Does the TO-220FP package require electrical isolation from the heatsink?
No-the TO-220FP package features an electrically insulated metal tab, so direct mounting to a grounded heatsink is permitted without thermal pad or mica insulator. This simplifies thermal design and improves heat transfer efficiency compared to standard TO-220 variants.
Can STB23NM60ND replace STP22NM60N in existing designs?
Yes-STB23NM60ND is a direct upgrade: identical pinout, same 600 V rating, lower RDS(on) (190 mΩ vs. 220 mΩ), and improved avalanche ruggedness. Layout changes are unnecessary, but gate drive strength should be verified due to slightly higher Qg (45 nC vs. 40 nC).
Is the body diode suitable for synchronous rectification in flyback converters?
No-the body diode is optimized for unclamped inductive switching, not low-loss rectification. Its VF is ~2.5 V and trr is 75 ns, making it unsuitable for secondary-side synchronous rectification. It is intended for primary-side freewheeling or active clamp functions only.
