Product details
Overview
IRF1405ZSPBF from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode HEXFET® Power MOSFET in D2Pak (TO-263) package, rated for 55 V VDSS, 4.9 mΩ RDS(on) at VGS = 10 V, and 75 A continuous drain current at TC = 25°C. It features 175°C junction temperature rating, fast switching (tr = 110 ns), and tested repetitive avalanche capability up to Tjmax, making it suitable for high-current DC-DC converters and motor drive half-bridges.
For engineers reviewing the IRF1405ZSPBF datasheet, IRF1405ZSPBF pinout, IRF1405ZSPBF application, or IRF1405ZSPBF equivalent, key selection criteria include on-resistance vs. thermal derating, gate charge (Qg = 120–180 nC), body diode recovery (Qrr = 30–45 nC), and avalanche energy rating (EAS = 150 mJ).
Technical Context
This MOSFET employs advanced silicon processing to minimize conduction loss per unit area while maintaining robustness under transient overloads. Its low RDS(on) of 3.7–4.9 mΩ and high ID capability (75 A) enable efficient operation in high-current, medium-voltage power stages such as synchronous rectifiers and battery protection circuits.
The device integrates a co-packaged body diode with VSD ≤ 1.3 V and trr = 30–46 ns, supporting moderate-frequency hard-switching topologies. Thermal design is enabled by RθJC = 0.65°C/W and validated repetitive avalanche performance up to IAS = 75 A with L = 0.10 mH.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 55 V - Maximum blocking voltage before avalanche onset; defines upper limit for bus voltage in buck converters and H-bridge drivers. |
| RDS(on) | 4.9 mΩ max @ VGS = 10 V - Directly determines I²R conduction loss; enables <1.5 W loss at 75 A DC. |
| ID (cont) | 75 A @ TC = 25°C - Continuous current handling capacity when case is actively cooled; limited to 270 A pulsed (IDM). |
| Qg | 120–180 nC - Total gate charge required for full turn-on; impacts driver sizing and switching loss in PWM applications. |
| EAS | 150 mJ - Single-pulse avalanche energy rating; supports unclamped inductive switching without failure if Tj ≤ 175°C. |
| tr/tf | 110 ns / 82 ns - Rise/fall times define minimum practical switching frequency and EMI profile in hard-switched topologies. |
| TJ max | 175°C - Maximum allowable junction temperature; sets thermal margin for heatsink design and derating curves. |
Pinout & Package
IRF1405ZSPBF uses the surface-mount D2Pak (TO-263) package with three terminals: Drain (tab), Source (pins 2 & 3), and Gate (pin 1). The exposed drain pad provides low-inductance, high-current path and serves as primary thermal interface to PCB copper or heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main high-side current path and thermal interface | Electrically connected to internal die drain; requires soldered thermal pad for RθJC = 0.65°C/W performance. |
| Source (Pins 2 & 3) | Return path for load current and gate reference | Low-inductance dual-pin layout minimizes source loop inductance during switching transitions. |
| Gate (Pin 1) | Control terminal for channel modulation | High-impedance input requiring 10 V for full enhancement; Qgs = 31 nC and Qgd = 46 nC define Miller effect timing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) | 4.9 mΩ enables <1.5 W conduction loss at 75 A, reducing heatsink requirements in high-current 12–48 V systems. |
| 175°C junction rating | Extends operational margin in sealed enclosures or high-ambient environments without derating to 150°C. |
| Repetitive avalanche rated | Validated for repeated unclamped inductive switching up to IAS = 75 A, eliminating need for external snubbers in motor drive flyback paths. |
| Fast body diode recovery | Qrr = 30–45 nC and trr = 30–46 ns reduce reverse recovery loss and EMI in synchronous rectification and bidirectional DC-DC stages. |
Applications
| DC-DC Buck Converter | Brushed DC Motor Driver |

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 |
|---|---|---|---|
| STP75NF75 | RDS(on) = 10.5 mΩ @ 10 V; VDSS = 75 V; TO-220 package | Higher voltage rating but double RDS(on); larger package footprint and higher RθJA | Select when 75 V blocking is required and thermal budget permits higher conduction loss. |
| IXTP75N055T | RDS(on) = 5.5 mΩ @ 10 V; VDSS = 55 V; TO-220 package; lower Qg (100 nC) | Same voltage/current class but through-hole mounting; slightly higher RDS(on) and no avalanche rating | Select for legacy through-hole designs where D2Pak rework is impractical and avalanche robustness is not critical. |
Compared with STP75NF75 and IXTP75N055T, IRF1405ZSPBF offers the lowest RDS(on) in surface-mount form with verified repetitive avalanche capability-critical for motor drives and UPS inverters where inductive stress is routine.

FAQ
What is the maximum continuous drain current for IRF1405ZSPBF at 100°C case temperature?
The maximum continuous drain current drops to 270 A at TC = 100°C only under pulsed conditions (IDM). For continuous operation, the datasheet specifies 230 A at TC = 100°C with VGS = 10 V. This reflects thermal limitation-not silicon current density-and assumes adequate heatsinking to maintain case temperature.
Does IRF1405ZSPBF have a specified gate threshold voltage range?
Yes, VGS(th) is specified as 2.0 V minimum to 4.0 V maximum at TJ = 25°C and ID = 250 µA. This range ensures consistent turn-on behavior across production lots and supports compatibility with standard 3.3 V and 5 V logic-level gate drivers when used with appropriate margin.
Can IRF1405ZSPBF be used in parallel configurations?
Yes-its positive temperature coefficient of RDS(on) (see Fig. 10) enables inherent current sharing when paralleled. Designers must match gate drive impedance and layout symmetry to minimize dynamic imbalance; typical practice uses individual 10 Ω gate resistors and Kelvin-source routing to ensure equalized switching.
Is the body diode in IRF1405ZSPBF suitable for synchronous rectification?
No-the integrated body diode has relatively high VSD (≤1.3 V) and moderate Qrr (30–45 nC), making it unsuitable for high-frequency synchronous rectification where low forward drop and ultrafast recovery are essential. External Schottky or GaN FETs are preferred for that role.
