Product details
Overview
STP30NM50N from STMicroelectronics is an N-channel 500 V, 27 A, 0.090 Ω RDS(on) MDmesh™ II Power MOSFET in TO-220 package, designed for high-efficiency switching converters. It features 100% avalanche tested ruggedness, low gate charge (94 nC), and low input capacitance (2740 pF), enabling fast switching in offline SMPS, PFC stages, and industrial motor drives.
For engineers reviewing the STP30NM50N datasheet, STP30NM50N pinout, STP30NM50N application, or STP30NM50N equivalent, key selection criteria include its 500 V VDSS, 0.090 Ω RDS(on) at VGS = 10 V, 94 nC total gate charge, 150 °C max junction temperature, and TO-220 thermal resistance of 3.1 °C/W (junction-to-case).
Technical Context
This device uses ST's second-generation MDmesh™ vertical structure combined with strip layout to minimize conduction and switching losses simultaneously. Its 500 V breakdown voltage and 27 A continuous drain current support operation in universal-input AC-DC converters up to 3 kW.
The MOSFET delivers 900 mJ single-pulse avalanche energy and supports 15 V/ns dv/dt robustness under inductive switching. Its source-drain diode exhibits 480 ns reverse recovery time and 8 µC Qrr at Tj = 25 °C, enabling efficient hard-switched topologies without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 500 V - Withstands full rectified 380 VAC line surges in offline PSUs without breakdown |
| RDS(on) max | 0.115 Ω - Ensures ≤ 84 W conduction loss at 27 A, critical for thermal management in enclosed enclosures |
| Qg | 94 nC - Enables <100 ns switching transitions with 10 Ω gate driver, reducing turn-on loss in 100 kHz designs |
| ID (TC = 25 °C) | 27 A - Supports peak power delivery in 1–3 kW industrial power supplies with forced-air cooling |
| Rthj-case | 3.1 °C/W - Allows 61 W dissipation at ΔT = 190 °C (150 °C Tj − 25 °C TC), matching standard TO-220 heatsinks |
| EAS | 900 mJ - Sustains unclamped inductive switching events in relay drivers or solenoid controls without failure |
| Ciss | 2740 pF - Low enough to avoid excessive Miller-induced shoot-through in half-bridge configurations |
Pinout & Package
STP30NM50N is housed in a through-hole TO-220 package with isolated tab (pin 2 connected to drain). The package provides mechanical robustness, standardized mounting, and direct heatsink coupling via the metal tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Power return path for load current | Low-impedance connection to ground plane; carries full 27 A continuous current; referenced for gate drive |
| 2 (Drain) | Main high-side power terminal | Connected to internal die backside; electrically tied to metal tab; requires isolation from heatsink unless floating topology |
| 3 (Gate) | Control input for channel modulation | High-impedance MOS gate requiring <100 nC charge; sensitive to ESD; must be driven with <25 V to avoid oxide damage |
Key Features
| Feature | Design Value |
|---|---|
| 100% avalanche tested | Guarantees 12 A repetitive avalanche current and 900 mJ single-pulse energy survival under unclamped inductive loads |
| Low gate charge (94 nC) | Reduces gate driver power loss and enables use of cost-effective 1-A drivers in 65–100 kHz SMPS designs |
| Low RDS(on) (0.090 Ω typ.) | Lowers I²R conduction loss by >30% vs. first-gen 500 V MOSFETs, improving efficiency in high-current PFC stages |
| MDmesh™ II vertical structure | Optimizes cell pitch and drift region doping to achieve best-in-class figure-of-merit (RDS(on) × Qg) of 8.46 Ω·nC |
| ECOPACK® RoHS-compliant | Lead-free second-level interconnect meets JEDEC JESD97; compatible with standard SnPb and lead-free reflow profiles |

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 |
|---|---|---|---|
| IPP60R099C7 | 650 V VDSS, 0.099 Ω RDS(on), 71 nC Qg, TO-220 package | Higher voltage rating suits 400 V DC bus systems; lower Qg improves light-load efficiency | Prefer when designing for 650 V systems or needing lower gate drive loss; not drop-in due to different threshold voltage (3.5 V vs. 3.0 V) |
| FDPF18N50 | 500 V VDSS, 0.18 Ω RDS(on), 72 nC Qg, TO-220FP package | Higher RDS(on) increases conduction loss; TO-220FP offers insulated tab but lower power rating (40 W) | Select only for space-constrained layouts requiring insulated mounting; avoid in >1 kW designs due to thermal derating |
Compared with IPP60R099C7 and FDPF18N50, STP30NM50N delivers the lowest RDS(on) among TO-220 500 V MOSFETs, making it optimal for thermally constrained high-current applications where conduction loss dominates, while maintaining proven avalanche ruggedness for industrial reliability.

FAQ
What is the maximum continuous drain current for STP30NM50N at 100 °C case temperature?
The maximum continuous drain current is 17 A at TC = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limits of the TO-220 package, where junction-to-case thermal resistance (3.1 °C/W) and safe operating area constraints reduce current handling above 25 °C case temperature.
Does STP30NM50N have an integrated body diode, and what are its key recovery characteristics?
Yes, it includes a monolithic source-drain body diode rated for 27 A continuous and 108 A pulsed current. At Tj = 25 °C, its reverse recovery time is 480 ns, Qrr is 8 µC, and peak reverse recovery current is 33 A under 100 A/µs di/dt conditions - parameters critical for snubberless hard-switching design.
Can STP30NM50N be used in avalanche mode, and what is its rated avalanche energy?
Yes, it is 100% tested for repetitive and non-repetitive avalanche operation. The datasheet specifies 12 A maximum avalanche current and 900 mJ single-pulse avalanche energy at Tj = 25 °C, validated using unclamped inductive load testing per JEDEC standards.
What is the gate threshold voltage range, and how does it vary with temperature?
VGS(th) is specified from 2.0 V to 4.0 V at Tj = 25 °C, with typical value 3.0 V. Figure 14 shows normalized VGS(th) decreases ~0.5%/°C above 25 °C, reaching ~0.8× nominal at 150 °C - a key consideration for gate drive margin in high-temperature environments.
