Product details
Overview
IRF6619TR1PBF from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode Power MOSFET in DirectFET® MX package, optimized for synchronous buck converter high-side and low-side FET applications. It delivers 1.65 mΩ RDS(on) @ 10 V, 38 nC total gate charge, and 780 pF Crss - enabling high-efficiency, >1 MHz switching in CPU core DC-DC converters.
For engineers reviewing the IRF6619TR1PBF datasheet, IRF6619TR1PBF pinout, IRF6619TR1PBF application, or IRF6619TR1PBF equivalent, key selection criteria include Cdv/dt immunity, dual-sided cooling capability, ultra-low package inductance, and thermal resistance of 1.4 °C/W (Junction-to-Case), critical for thermally constrained point-of-load designs.
Technical Context
The IRF6619TR1PBF employs HEXFET® silicon with trench-gate structure and is packaged in a copper-can DirectFET® MX outline, where the top metal surface is the Drain and bottom substrate serves as Source/Drain terminals. Its gate threshold voltage (1.55–2.45 V) and negative temperature coefficient (−5.8 mV/°C) support stable parallel operation under thermal stress.
This device is specifically characterized for 12 V bus synchronous buck converters: it achieves 80% lower thermal resistance than prior SO-8 equivalents, supports 24 A pulsed drain current, and exhibits 18 nC reverse recovery charge (Qrr) with 29–44 ns trr - minimizing body diode conduction loss during dead-time transitions.
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, critical for high-current CPU VRMs |
| Qg | 38 nC typ - reduces gate drive power and allows use of smaller, lower-cost gate drivers |
| Crss | 780 pF - limits Miller-induced turn-on risk in high-dv/dt synchronous FET switching |
| RθJC | 1.4 °C/W - supports dual-sided cooling to maintain TJ < 125°C under 100 W dissipation |
| ID (cont, TC=25°C) | 240 A - package-limited rating reflecting copper-can thermal mass and interconnect robustness |
| VDS | 20 V - rated for 12 V input bus with margin for transient overshoot and ringing |
| Qrr | 18 nC typ - lowers energy loss during body diode commutation in hard-switched buck topologies |
Pinout & Package
IRF6619TR1PBF uses the DirectFET® MX package: a low-profile (0.7 mm), copper-can, double-sided cooling design with exposed top Drain and bottom Source/Drain terminals. The package footprint matches SO-8 layouts but eliminates leadframe inductance and thermal bottlenecks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Top Metal Surface | Drain (D) | Primary high-current path; thermally coupled to heatsink or PCB copper pour for dual-sided cooling |
| Bottom Substrate Pad (Large) | Source (S) | Main source return; electrically and thermally connected to PCB ground plane |
| Bottom Substrate Pad (Small) | Drain (D) | Secondary drain connection for improved current sharing and reduced loop inductance |
| Side Terminal (Exposed) | Gate (G) | Low-inductance gate interface; requires controlled-impedance routing to minimize oscillation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) + Qg product | 62.7 mΩ·nC - minimizes combined conduction and switching loss in high-frequency (>1 MHz) VRMs |
| DirectFET® MX copper-can construction | 1.4 °C/W RθJC - enables 80% lower thermal resistance vs. SO-8 MOSFETs, verified per Fig. 3 |
| Cdv/dt-induced turn-on immunity | Tested per sync-buck conditions - prevents false turn-on during high-slew-rate node transitions |
| Optimized for 12 V bus synchronous buck | Characterized at VGS = 4.5 V and 10 V - ensures robust operation with standard controller gate drive |
| Body diode Qrr and trr | 18 nC / 29–44 ns - reduces dead-time loss and EMI in hard-switched topologies |

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 |
|---|---|---|---|
| IRF6622TR1PBF | 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) = 1.75 mΩ @ 10 V; Qg = 33 nC; PowerPAK® SO-8 package | Higher RDS(on), lower Qg, no dual-sided cooling - RθJA = 45 °C/W vs. 12.5 °C/W (DirectFET) | Choose only if board-level cooling is limited to single-side and switching frequency <500 kHz |
Compared with IRF6622TR1PBF and SiR626DP-T1-GE3, the IRF6619TR1PBF offers the optimal balance of ultra-low RDS(on), moderate Qg, and superior thermal performance - making it uniquely suited for high-density, high-frequency CPU/GPU VRMs where junction temperature control is non-negotiable.

FAQ
What is the maximum continuous drain current for IRF6619TR1PBF at 70°C ambient?
The IRF6619TR1PBF supports 30 A continuous drain current at TA = 70°C with VGS = 10 V, as specified in the Absolute Maximum Ratings table. This rating assumes surface mounting on a 1-inch square copper board with steady-state conditions and thermocouple measurement at the top (Drain) surface per test methodology in the datasheet.
Does IRF6619TR1PBF require special PCB layout considerations for thermal performance?
Yes - optimal thermal performance requires using both top-side (Drain) and bottom-side (Source) copper planes for dual-sided cooling, per DirectFET Application Note AN-1035. The MX outline demands specific stencil aperture design and substrate pad geometry to ensure void-free solder joint formation and mechanical reliability under thermal cycling.
Can IRF6619TR1PBF be used in avalanche mode?
Yes - the device is rated for single-pulse avalanche energy (EAS) up to 890 mJ at TJ = 25°C, with allowable avalanche current dependent on pulse width and junction temperature rise. Repetitive avalanche operation is permitted only if TJ remains below 150°C, and must follow the derating curves in Figures 14 and 15.
Is IRF6619TR1PBF RoHS-compliant and halogen-free?
Yes - IRF6619TR1PBF is RoHS-compliant (2011/65/EU) and halogen-free per Infineon's material declarations. The "PBF" suffix explicitly denotes lead-free (Pb-free) plating and packaging, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements.
