Product details
Overview
IRF6619TRPBF from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode Power MOSFET in DirectFET® MX package, optimized for synchronous buck FETs in high-frequency DC-DC converters. It delivers 1.65 mΩ RDS(on) @ 10 V, 38 nC total gate charge, and 780 pF Crss, enabling low conduction and switching losses at >1 MHz operation for CPU core power delivery.
For engineers reviewing the IRF6619TRPBF datasheet, IRF6619TRPBF pinout, IRF6619TRPBF application, or IRF6619TRPBF equivalent, key selection criteria include Cdv/dt immunity, dual-sided cooling capability, ultra-low package inductance, and SO-8 footprint compatibility with 0.7 mm profile.
Technical Context
The IRF6619TRPBF employs HEXFET® silicon on a copper substrate DirectFET® MX package, enabling top-side (drain) and bottom-side (source) thermal paths. Its gate threshold voltage of 1.55–2.45 V and negative temperature coefficient (−5.8 mV/°C) support stable parallel operation in multiphase VRMs.
Designed specifically for 12 V input synchronous buck converters, it balances low RDS(on), low Qgd/Qgs2 ratio (3.8), and high Cdv/dt immunity to suppress false turn-on during high di/dt transitions in high-side switching configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 1.65 mΩ @ VGS = 10 V, TJ = 25°C - enables <1 W conduction loss at 30 A in CPU core rails |
| Qg | 38 nC - reduces gate drive power and supports >1 MHz PWM without excessive driver stress |
| Crss | 780 pF - limits Miller feedback, improving noise immunity in high dv/dt environments |
| RθJC | 1.4 °C/W - allows direct heatsink mounting to drain pad for efficient dual-sided cooling |
| VGS(th) | 1.55–2.45 V - ensures reliable turn-on with standard 3.3 V or 5 V gate drivers |
| ID (continuous) | 30 A @ TC = 25°C - sustains high current in compact VRM layouts with forced airflow |
| Qrr | 18 nC - minimizes body diode recovery loss during dead-time in synchronous rectification |
Pinout & Package
IRF6619TRPBF uses the DirectFET® MX outline: a copper-can, double-sided cooling package with no leads, mounted directly to PCB via top (drain) and bottom (source) metal pads. Footprint matches SO-8 but with 0.7 mm height and exposed drain on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Top Metal Pad | Drain (D) | Primary heat path and high-current output node; electrically connected to internal die drain |
| Bottom Metal Pad (large) | Source (S) | Main current return path and thermal interface to PCB ground plane |
| Bottom Metal Pad (small) | Gate (G) | Isolated gate connection; requires controlled trace routing to minimize coupling and ringing |
Key Features
| Feature | Design Value |
|---|---|
| Dual-sided cooling | Enables simultaneous thermal extraction from top (drain heatsink) and bottom (PCB copper), reducing RθJA by 80% vs. SO-8 |
| Ultra-low package inductance | Minimizes voltage overshoot and EMI during hard switching at >1 MHz, critical for sub-100 ns dead-time control |
| Cdv/dt-induced turn-on immunity | Validated for robust operation under high di/dt conditions in synchronous buck high-side position without external gate clamping |
| SO-8 footprint compatibility | Allows drop-in replacement in existing layouts without redesign; supports vapor-phase, IR, and convection reflow per AN-1035 |
| Optimized for 12 V bus converters | Parameters tuned for RDS(on), Qg, and Qgd trade-off specific to 12 V input, 1–2 V output VRMs powering modern CPUs |
Applications
| CPU Core Voltage Regulator | GPU Power Delivery |
|---|---|
Use Scenario: High-current, multi-phase buck converter supplying 0.8–1.3 V to Intel/AMD processors at up to 300 A peak. IC Role / Device Role / Timing Role: Synchronous FET in high-side position, switching at 500 kHz–1.5 MHz with precise dead-time control. Use Value: 1.65 mΩ RDS(on) and 38 nC Qg reduce combined conduction + switching loss to <1.2 W per phase at 30 A, enabling higher efficiency at full load. | Use Scenario: Compact, high-density VRM on graphics card PCB delivering 0.9–1.2 V to GPU die with tight thermal constraints. IC Role / Device Role / Timing Role: Low-profile power switch operating in parallel configuration with integrated gate drivers. Use Value: 0.7 mm profile and dual-sided cooling allow placement under heatsinks; 780 pF Crss prevents false turn-on during fast GPU load transients. |
| Server Memory Regulator | AI Accelerator Power Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF6622TRPBF | RDS(on) = 1.35 mΩ @ 10 V, Qg = 42 nC, same MX package | Slightly lower RDS(on) but higher gate charge increases driver loss at >1 MHz | Prefer when conduction loss dominates; verify gate driver capability for 42 nC load |
| SiR626DP-T1-GE3 | RDS(on) = 1.5 mΩ @ 10 V, Qg = 35 nC, PowerPAK® SO-8 package | Lower Qg improves switching efficiency but lacks dual-sided cooling and has higher RθJA | Prefer when board space is constrained and top-side cooling is unavailable |
Compared with IRF6622TRPBF and SiR626DP-T1-GE3, the IRF6619TRPBF offers the optimal balance of low RDS(on), moderate Qg, and superior thermal performance via DirectFET® dual-sided cooling-making it uniquely suited for thermally demanding, high-frequency CPU/GPU VRMs where both electrical and thermal margins are critical.

FAQ
What is the maximum continuous drain current for IRF6619TRPBF at 70°C ambient?
The IRF6619TRPBF supports 20 A continuous drain current at TA = 70°C with surface-mount mounting on a 1 in² copper board. This rating assumes still air and accounts for thermal derating beyond 25°C ambient, as specified in the Absolute Maximum Ratings table on page 2 of the official datasheet.
Does IRF6619TRPBF require special PCB layout considerations for thermal performance?
Yes-optimal thermal performance requires dedicated copper areas on both top (for drain pad heatsinking) and bottom (for source pad conduction) layers, per DirectFET® AN-1035 guidelines. Minimum recommended copper area is 1 in² per side, with thermal vias under the source pad to inner ground planes.
Can IRF6619TRPBF be used in avalanche mode?
Yes-the IRF6619TRPBF is rated for single-pulse avalanche energy (EAS) up to 1000 mJ at TJ = 25°C. Repetitive avalanche is permitted only if junction temperature remains below 150°C and pulse parameters comply with Figures 14–15 and AN-1005 guidance on transient thermal impedance.
Is IRF6619TRPBF RoHS-compliant and halogen-free?
Yes-IRF6619TRPBF is RoHS-compliant (2011/65/EU) and halogen-free per IEC 61249-2-21. The "TRPBF" suffix confirms lead-free plating and green packaging; full compliance documentation is available in Infineon's material declaration database under order code IRF6619TRPBF.
