Product details
Overview
IRF7455TRPBF-1 from Infineon Technologies (formerly International Rectifier) is a 30 V, 15 A logic-level N-channel MOSFET in SO-8 package, optimized for synchronous rectification in high-frequency DC-DC converters. It features 7.5 mΩ RDS(on) at VGS = 10 V, 37 nC total gate charge, and integrated body diode with 64 ns reverse recovery time-enabling efficient operation in 48 V telecom SMPS topologies.
For engineers reviewing the IRF7455TRPBF-1 datasheet, IRF7455TRPBF-1 pinout, IRF7455TRPBF-1 application, or IRF7455TRPBF-1 equivalent, key selection criteria include logic-level gate drive compatibility (VGS(th) = 0.6–2.0 V), low conduction loss in continuous 12 A operation at 70°C, and SO-8 footprint suitability for multi-vendor board reuse in telecom power stages.
Technical Context
This MOSFET is designed for high-frequency switching in synchronous buck and forward converters where fast turn-on/turn-off dynamics are critical. Its 17 ns turn-on delay, 18 ns rise time, and 51 ns turn-off delay support >500 kHz operation; the 100 pF Crss and 3480 pF Ciss values reflect optimized Miller effect control for stable gate driving under hard-switching conditions.
The device integrates a robust body diode (IS = 15 A continuous, Qrr = 99–150 nC) enabling bidirectional current handling in synchronous rectifier configurations. Thermal resistance of 50 °C/W (junction-to-ambient, PCB-mounted) and MSL1 qualification ensure reliability in industrial ambient environments up to +70°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage compatible with 48 V input rail derating and transient margin in telecom SMPS |
| RDS(on) @ VGS = 10 V | 7.5 mΩ - Enables <1.7 W conduction loss at 15 A DC, reducing thermal load in compact DC-DC modules |
| Qg | 37 nC (typ.) - Determines gate driver current requirement (~1.85 A peak for 20 ns rise with 2 Ω driver) |
| ID @ TA = 70°C | 12 A - Sustained output current capability under industrial ambient conditions without forced cooling |
| tr/tf | 18 ns / 44 ns - Supports clean zero-voltage switching transitions and minimizes overlap loss in synchronous rectifiers |
| VGS(th) | 0.6–2.0 V - Ensures full enhancement with standard 3.3 V or 5 V logic-level controllers (e.g., TI UCC27xxx) |
| Qrr | 99–150 nC - Quantifies stored charge in body diode; directly impacts switching loss during commutation in synchronous FETs |
Pinout & Package
IRF7455TRPBF-1 is housed in a standard SO-8 surface-mount package (JEDEC MS-012AA), qualified to MSL1 and RoHS/halogen-free standards. The package supports automated assembly and offers thermal performance of 50 °C/W (junction-to-ambient, on 1-inch² copper).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Drain (D) | High-current power output node; internally paralleled pins reduce source inductance and improve current sharing |
| 6 | Gate (G) | Control terminal requiring ≤2.0 V threshold; sensitive to ESD but compatible with standard logic drivers |
| 7, 8 | Source (S) | Power return path and reference for gate drive; dual pins lower loop inductance in high-di/dt switching |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | VGS(th) as low as 0.6 V enables direct interface with 3.3 V microcontrollers and PWM controllers without level-shifting |
| Low RDS(on) | 7.5 mΩ at 10 V reduces conduction loss by >30% vs. legacy 12 mΩ SO-8 MOSFETs in 12 A telecom rails |
| Optimized gate charge | 37 nC Qg balances switching speed and driver loading-critical for minimizing gate loss in >300 kHz SMPS |
| Enhanced body diode | 64 ns trr and 99 nC Qrr reduce reverse recovery loss versus standard MOSFETs in synchronous rectifier mode |
| SO-8 industry footprint | JEDEC MS-012AA outline ensures drop-in replacement across vendors and simplifies PCB redesign for supply chain continuity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SiR872DP-T1-GE3 | RDS(on) = 5.2 mΩ @ 10 V; Qg = 42 nC; SO-8 package | Lower conduction loss but higher gate charge increases driver loss above 1 MHz | Preferred for fixed 48 V input converters prioritizing efficiency over switching frequency |
| DMN3020LFG-7 | RDS(on) = 8.5 mΩ @ 10 V; Qg = 28 nC; same SO-8 footprint | Reduced gate drive demand suits low-power controllers but higher RDS(on) raises thermal load at >10 A | Better fit for cost-sensitive 5–8 A POL regulators with limited board space for thermal relief |
Compared with SiR872DP-T1-GE3 and DMN3020LFG-7, IRF7455TRPBF-1 delivers optimal balance of low RDS(on), moderate Qg, and proven telecom reliability-making it ideal for 10–15 A synchronous rectifier roles where thermal headroom and gate drive simplicity are both critical.

FAQ
Is IRF7455TRPBF-1 suitable for 3.3 V gate drive?
Yes. With a gate threshold voltage range of 0.6–2.0 V and guaranteed enhancement at VGS = 4.5 V, IRF7455TRPBF-1 fully turns on using standard 3.3 V logic outputs. RDS(on) rises to ~9 mΩ at VGS = 4.5 V, which remains acceptable for many 12 A applications with appropriate thermal design.
What is the maximum continuous drain current at 85°C ambient?
At TA = 85°C, the device's maximum continuous drain current is approximately 10.5 A, derived from linear derating (0.02 W/°C) applied to its 2.5 W PD rating at 25°C and thermal resistance of 50 °C/W. This assumes standard SO-8 mounting on 1-inch² copper.
Does IRF7455TRPBF-1 have avalanche rating?
No. The datasheet does not specify unclamped inductive switching (UIS) or repetitive avalanche energy ratings. It is intended for use in circuits with controlled switching and clamping-designers must ensure voltage transients remain within the 30 V VDS limit using snubbers or active clamp topologies.
Can IRF7455TRPBF-1 replace IRF7455PbF-1 in existing designs?
Yes. IRF7455TRPBF-1 is the tape-and-reel version of the same die and package as IRF7455PbF-1 (tube version). Both share identical electrical specifications, thermal characteristics, and SO-8 mechanical outline-ensuring full form-fit-function compatibility in automated manufacturing.
