Product details
Overview
IRF3315STRR from Infineon Technologies (formerly International Rectifier) is a 150 V, 48 A, 22 mΩ N-channel HEXFET® Power MOSFET in TO-263 (D²PAK) package, optimized for high-efficiency DC-DC conversion and motor control in industrial power supplies and UPS systems.
For engineers reviewing the IRF3315STRR datasheet, IRF3315STRR pinout, IRF3315STRR application, or IRF3315STRR equivalent, key selection criteria include RDS(on) at 10 V gate drive, peak pulsed drain current rating, thermal resistance (RθJC), and avalanche energy capability under repetitive switching conditions.
Technical Context
This MOSFET employs planar stripe cell structure with optimized gate oxide thickness and source/drain doping profiles to achieve low on-resistance while maintaining robust short-circuit withstand time (≥10 µs at VDD = 75 V, TJ = 25 °C). It features fully rated avalanche capability per JEDEC JESD24-01.
The device uses a thermally enhanced D²PAK package with exposed drain pad for direct PCB thermal coupling, enabling junction-to-case thermal resistance of 0.95 °C/W - critical for high-current synchronous rectification stages in 48 V intermediate bus converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 150 V - supports 100 V nominal input rails with 50 % safety margin for transient overvoltage in telecom and server PSUs |
| RDS(on) @ VGS = 10 V | 22 mΩ max - enables <1.1 W conduction loss at 48 A DC, reducing heatsink requirements in compact 1 kW modules |
| ID (continuous) | 48 A @ TC = 100 °C - sustains full load in forced-air cooled motor drives without derating |
| EAS | 330 mJ - allows reliable operation in inductive switching circuits without external snubbers |
| RθJC | 0.95 °C/W - permits 65 °C temperature rise across junction-to-case path at 70 W dissipation |
| Qg | 95 nC - determines gate driver current requirement (~1.9 A peak for 50 ns turn-on with 50 Ω gate resistor) |
Pinout & Package
Package: TO-263 (D²PAK), surface-mount, thermally enhanced with exposed drain pad on bottom side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Accepts 0–20 V logic-level signal; requires 95 nC total charge for full enhancement |
| 2 (Drain) | High-side power terminal | Internally connected to exposed copper pad; must be soldered to large PCB copper area for thermal conduction |
| 3 (Source) | Reference node for gate drive | Serves as return path for load current and gate drive loop; low-inductance layout essential for EMI control |
Key Features
| Feature | Design Value |
|---|---|
| 100 % UIS tested | Each unit validated for unclamped inductive switching stress up to 330 mJ, eliminating need for batch screening |
| Lead-free and RoHS compliant | Meets EU Directive 2011/65/EU; Pb-free plating on leads and die attach ensures compatibility with lead-free reflow profiles |
| Fast body diode recovery | trr = 60 ns - reduces switching losses in synchronous buck topologies by minimizing reverse recovery charge (Qrr = 55 nC) |
| Enhanced dv/dt ruggedness | Rated for 4.5 V/ns - prevents false turn-on during high-speed switching in half-bridge configurations |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP150N10F7 | RDS(on) = 10.5 mΩ @ 10 V, VDS = 100 V, Qg = 105 nC | Limited to 100 V systems; higher gate charge increases driver loss | Preferred where lower RDS(on) justifies reduced voltage margin and added gate drive complexity |
| IXFH44N15 | RDS(on) = 32 mΩ @ 10 V, VDS = 150 V, EAS = 420 mJ | Higher on-resistance but superior avalanche robustness | Chosen for mission-critical inverters requiring extended unclamped inductive switching endurance |
Compared with STP150N10F7 and IXFH44N15, IRF3315STRR offers optimal balance of 150 V rating, 22 mΩ conduction loss, and 330 mJ avalanche energy - making it ideal for 48–100 V industrial power stages where thermal density and reliability are jointly constrained.

FAQ
Is IRF3315STRR pin-compatible with IRF3315PbF?
Yes - both share identical TO-263 (D²PAK) footprint and pin assignment (G-D-S). The "STRR" suffix denotes tape-and-reel packaging with lead-free finish, while "PbF" indicates same die and construction with RoHS-compliant plating. No layout change is required for substitution.
What is the maximum recommended gate resistor value for hard-switching at 200 kHz?
A 10 Ω gate resistor is recommended to limit peak gate current to ~2 A while achieving <50 ns turn-on delay and <25 ns rise time. Higher values increase switching losses; lower values risk gate driver overstress due to 95 nC Qg and parasitic oscillation.
Does IRF3315STRR support paralleling for higher current capacity?
Yes - its positive temperature coefficient of RDS(on) enables stable current sharing. Use matched gate resistors (±5 %), symmetrical PCB layout, and Kelvin source connections to minimize imbalance; derate total current by 15 % for thermal margin when paralleling two units.
Can IRF3315STRR replace IRF1404 in existing designs?
No - IRF1404 has 40 V VDS and 162 A rating; IRF3315STRR's 150 V rating and 48 A current make it unsuitable as a drop-in replacement. Substitution requires full re-evaluation of voltage stress, gate drive, and thermal design due to different SOA and avalanche characteristics.
