Product details
Overview
IRF7757TRPBF from Infineon Technologies (formerly International Rectifier) is a dual N-channel TSSOP-8 packaged MOSFET with common-drain configuration, 20 V VDS, 35 mΩ RDS(on) @ 4.5 V VGS, and 4.8 A continuous drain current at 25°C - designed for compact battery management and load switching in portable electronics.
For engineers reviewing the IRF7757TRPBF datasheet, IRF7757TRPBF pinout, IRF7757TRPBF application, or IRF7757TRPBF equivalent, key selection criteria include its ultra-low on-resistance in a space-saving TSSOP-8 footprint (<1.2 mm height), dual-channel common-drain topology, and specified body diode recovery (trr = 20–30 ns).
Technical Context
This device integrates two matched N-channel enhancement-mode MOSFETs in a single TSSOP-8 package with shared drain terminals (pins 5–8), enabling synchronous high-side/low-side or dual-load control without external interconnects. Its gate threshold voltage (0.6–1.2 V) supports direct logic-level drive from 2.5 V and 3.3 V microcontrollers.
The MOSFETs feature low gate charge (Qg = 15–23 nC), fast switching (td(on) = 9.5 ns, tf = 14 ns), and optimized capacitance profile (Ciss = 1340 pF, Crss = 132 pF) for efficient DC-DC converter and power OR-ing applications requiring minimal Miller effect and controlled dv/dt.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 20 V - Maximum blocking voltage for battery-input circuits up to 2-cell Li-ion (8.4 V) with margin. |
| RDS(on) | 35 mΩ @ VGS = 4.5 V - Enables <170 mW conduction loss at 4.8 A, critical for thermally constrained PCBs. |
| ID (25°C) | 4.8 A continuous - Supports dual 2.4 A loads or single high-current path with derating above 70°C. |
| Qg | 15–23 nC - Low gate drive energy reduces controller loading and enables use with low-power GPIOs. |
| trr | 20–30 ns - Fast body diode recovery minimizes shoot-through risk and improves efficiency in bidirectional switching. |
| TJ Range | −55 to +150 °C - Qualified for extended industrial and automotive cabin-temperature environments. |
| RθJA | 105 °C/W - Thermal resistance measured on 1-in² Cu board; requires thermal pad or copper pour for >1 W operation. |
Pinout & Package
TSSOP-8 (JEDEC MO-153AA), 4.4 × 3.0 × 1.1 mm, surface-mount, lead-free, common-drain dual N-channel configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Source 1 (S1) | Low-side return path for Channel 1; electrically isolated from S2. |
| 2 | Gate 1 (G1) | Independent gate control input for Channel 1; no internal pull-down. |
| 3 | Source 2 (S2) | Low-side return path for Channel 2; independent of S1. |
| 4 | Gate 2 (G2) | Independent gate control input for Channel 2; fully decoupled from G1. |
| 5–8 | Common Drain (D) | All four drain terminals internally bonded together - forms single high-side output node. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 35 mΩ @ 4.5 V - Reduces I²R losses by >30% vs. comparable SO-8 duals, extending battery runtime. |
| TSSOP-8 footprint | 45% smaller area than SO-8 - Enables dense layout in PCMCIA cards and ultrathin mobile accessories. |
| Common-drain architecture | Single high-side node with dual independent sources/gates - simplifies PCB routing for dual-load OR-ing or redundant supply paths. |
| Logic-level gate drive | VGS(th) = 0.6–1.2 V - Direct interface with 1.8 V, 2.5 V, and 3.3 V MCUs without level-shifting circuitry. |
| Enhanced thermal performance | RθJA = 105 °C/W on standard FR4 - Achieves 1.2 W dissipation at ΔT = 126°C, supporting higher peak currents. |
Applications
| Battery Protection Circuit | USB Power Delivery Switching |
|---|---|
Use Scenario: Dual-MOSFET protection IC controlling charge/discharge paths in 2S Li-ion packs with overcurrent and short-circuit cutoff. IC Role / Device Role / Timing Role: Dual N-channel switch implementing back-to-back configuration for bidirectional blocking and precise current sensing via separate S1/S2. Use Value: Common-drain topology allows single-point high-side connection to pack+ while isolating sense resistors at S1/S2 - eliminating need for floating sense amplifiers. | Use Scenario: USB-C port power path management selecting between host and device power sources with reverse-current blocking. IC Role / Device Role / Timing Role: Dual-channel load switch enabling simultaneous control of VBUS and CC line power paths with independent enable timing. Use Value: Matched RDS(on) and fast trr ensure symmetrical forward/reverse conduction and prevent cross-conduction during hot-plug transitions. |
| PCMCIA Card Power Control | Portable Medical Sensor Hub |
Use Scenario: Hot-swap power sequencing for Type II PCMCIA peripherals with inrush limiting and fault isolation. IC Role / Device Role / Timing Role: Dual N-MOSFET acting as independent 5 V and 3.3 V rail switches with programmable turn-on delay via gate RC networks. Use Value: Ultra-thin 1.1 mm profile fits within PCMCIA mechanical envelope; low Qg enables soft-start using small gate resistors without MCU intervention. | Use Scenario: Multi-sensor data acquisition module powered by coin cell or rechargeable LiPo, requiring low-quiescent-power load switching. IC Role / Device Role / Timing Role: Dual independent load switches enabling selective power gating of BLE radio, ADC, and optical sensor subsystems. Use Value: Sub-1 V VGS(th) ensures reliable turn-on from weakly regulated 2.2 V LDO outputs; low RDS(on) preserves battery capacity across all active states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel load switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7157DP-T1-GE3 | RDS(on) = 42 mΩ @ 4.5 V; SO-8 package; higher RθJA (125 °C/W); no common-drain pinout. | Requires external drain tie; larger PCB area; less suitable for ultra-thin designs. | Preferred when SO-8 compatibility or higher surge rating (IDM = 24 A) is prioritized over size. |
| DMN3026LSD-13 | RDS(on) = 28 mΩ @ 4.5 V; same TSSOP-8; separate drain pins (no common-drain); higher gate charge (Qg = 28 nC). | Enables independent drain routing but increases layout complexity for OR-ing topologies. | Chosen when channel isolation is required (e.g., differential sensing) and lower on-resistance justifies added gate drive effort. |
Compared with Si7157DP-T1-GE3 and DMN3026LSD-13, the IRF7757TRPBF uniquely combines common-drain integration, sub-1.2 mm height, and 35 mΩ on-resistance - making it optimal for space-constrained, single-node high-side switching where layout simplicity and thermal density matter most.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The IRF7757TRPBF supports 3.9 A continuous drain current at TA = 70°C with VGS = 4.5 V, based on its 0.76 W power dissipation limit and 9.5 mW/°C linear derating factor. This reflects real-world thermal constraints on standard FR4 PCBs without heatsinking.
Can this device be used in a back-to-back configuration for AC blocking?
Yes - the dual independent source terminals (S1, S2) and common drain allow implementation of a back-to-back N-channel configuration for bidirectional blocking. The body diodes are oriented anode-to-anode, enabling full AC path control when both gates are driven synchronously.
Is the TSSOP-8 package compatible with standard reflow profiles?
Yes - the IRF7757TRPBF is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260°C for 30 seconds. Its thermal pad design and solderable terminations support automated assembly on standard SMT lines.
Does the device include integrated ESD protection on gate terminals?
No - the IRF7757TRPBF does not integrate gate ESD protection diodes. External 10 kΩ current-limiting resistors and/or TVS clamps are recommended on G1/G2 lines when exposed to handling or system-level ESD events per IEC 61000-4-2 Level 3.
