Product details
Overview
IRF6218STRLPBF from Infineon is a -150V, 27A, 150mΩ (at VGS = -10V) N-channel enhancement-mode HEXFET® Power MOSFET in D2-Pak (TO-263AB) package, designed for high-voltage switching in active-clamp reset DC-DC converters and industrial SMPS.
For engineers reviewing the IRF6218STRLPBF datasheet, IRF6218STRLPBF pinout, IRF6218STRLPBF application, or IRF6218STRLPBF equivalent, key selection criteria include avalanche-rated operation (210 mJ), low gate-to-drain charge (32 nC), effective output capacitance (340 pF), and junction-to-case thermal resistance (0.61 °C/W).
Technical Context
This MOSFET operates as a high-side or low-side switch in hard-switched and resonant topologies. Its negative threshold voltage (-3.0 to -5.0 V), fully characterized Coss (370 pF at VDS = -25 V), and specified dv/dt immunity (8.2 V/ns) support robust gate drive design in high-di/dt environments.
The device features integrated body diode with 150 ns reverse recovery time and 860 nC Qrr, enabling reliable unclamped inductive switching. Avalanche energy rating (210 mJ) and RθJC = 0.61 °C/W allow sustained operation under transient overloads when mounted on thermally optimized PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -150 V - supports 120 V bus designs with 25% safety margin |
| RDS(on) | 150 mΩ @ VGS = -10 V - enables <1.2 W conduction loss at 27 A |
| ID (continuous) | -27 A @ TC = 25°C - rated for high-current primary-side switching |
| Qgd | 32 nC - determines Miller-induced turn-off delay in high-dv/dt circuits |
| EAS | 210 mJ - allows single-pulse avalanche survival without external snubbing |
| RθJC | 0.61 °C/W - enables 250 W power dissipation with ≤153°C junction rise above case |
| trr | 150 ns - defines minimum dead-time requirement in synchronous rectification |
Pinout & Package
Package: D2-Pak (TO-263AB), surface-mount, isolated tab (drain-connected), 3-terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G | Gate | Control terminal; requires -10 V for full enhancement; threshold range -3.0 to -5.0 V |
| D | Drain | Main current path anode; electrically connected to exposed metal tab; must be isolated from heatsink unless referenced to same potential |
| S | Source | Reference node for gate drive; carries full load current and body diode return path |
Key Features
| Feature | Design Value |
|---|---|
| Low Qgd/Qgs ratio | 32 nC / 21 nC = 1.52 - reduces risk of false turn-on during high dv/dt commutation |
| Fully characterized Coss(eff) | 340 pF from 0 to -120 V - enables accurate soft-switching timing prediction in LLC/ZVS designs |
| Avalanche-rated construction | 210 mJ single-pulse EAS - eliminates need for external clamping in active-clamp flyback/forward converters |
| Lead-free and RoHS-compliant | Pb-free plating and halogen-free molding compound - meets IPC-J-STD-020 moisture sensitivity level 3 (MSL3) |
Applications
| Active-Clamp Forward Converter | High-Voltage DC-DC Isolated PSU |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTP120N15T | 150 V, 120 A, RDS(on) = 12.5 mΩ @ -10 V; TO-220 package; higher current, lower RDS(on), larger footprint | Requires larger heatsink area; unsuitable for space-constrained D2-Pak layouts | Select when conduction loss dominates and board real estate permits TO-220 mounting |
| STP14NF15 | 150 V, 14 A, RDS(on) = 180 mΩ @ -10 V; TO-220; lower current rating, higher on-resistance | Limited to ≤15 A continuous; not rated for 210 mJ avalanche | Acceptable only for derated, non-avalanche-critical 12 V–24 V auxiliary supplies |
Compared with IXTP120N15T and STP14NF15, IRF6218STRLPBF uniquely balances 27 A current capability, D2-Pak surface-mount compatibility, and certified 210 mJ avalanche robustness-making it optimal for compact, high-reliability active-clamp SMPS where thermal and layout constraints preclude TO-220 alternatives.

FAQ
What is the maximum allowable gate-to-source voltage for IRF6218STRLPBF?
The absolute maximum VGS is ±20 V. Operation beyond ±15 V risks permanent gate oxide damage. Recommended drive is -10 V for full enhancement and +0 V (or slight positive bias ≤2 V) for turn-off to avoid unintended conduction due to noise coupling.
Does IRF6218STRLPBF require a gate resistor, and what value is recommended?
Yes-a gate resistor is required to control dI/dt and suppress oscillation. For typical 100–500 kHz SMPS operation, a 3.9 Ω resistor is validated in the datasheet for turn-off delay (35 ns) and fall time (30 ns); values between 2.2 Ω and 10 Ω balance switching speed and ringing suppression.
Can IRF6218STRLPBF be used in parallel configurations?
Yes, but only with matched devices and symmetrical PCB layout. The device's positive RDS(on) temperature coefficient (−0.17 V/°C breakdown drift) supports current sharing; however, gate drive skew and parasitic inductance must be minimized to prevent dynamic imbalance during switching transitions.
Is the drain tab electrically isolated in the D2-Pak package?
No-the drain is directly connected to the exposed metal tab. Electrical isolation from the heatsink is mandatory unless the heatsink is referenced to the drain potential. Use silicone-insulating pads or ceramic washers with thermal conductivity ≥1.5 W/m·K and dielectric strength ≥2 kV.
