Product details
Overview
IRF3415SPBF from Infineon Technologies is a 150 V, 43 A, N-channel enhancement-mode HEXFET® Power MOSFET in TO-220AB package, featuring 55 mΩ RDS(on) at VGS = 10 V and 175 °C junction temperature, designed for high-efficiency DC-DC converters and motor control circuits in industrial power supplies.
For engineers reviewing the IRF3415SPBF datasheet, IRF3415SPBF pinout, IRF3415SPBF application, or IRF3415SPBF equivalent, key selection criteria include its low gate charge (71 nC), fast switching speed (trise = 45 ns), rugged avalanche rating (EAS = 330 mJ), and lead-free TO-220AB packaging compliant with RoHS Directive 2011/65/EU.
Technical Context
This MOSFET employs planar stripe cell geometry with optimized gate oxide thickness to achieve stable threshold voltage (VGS(th) = 2.0–4.0 V) and low input capacitance (Ciss = 2200 pF). Its integrated body diode exhibits reverse recovery time (trr) of 120 ns and Qrr of 55 nC under IF = 43 A conditions.
The device operates with continuous drain current up to 43 A at TC = 25 °C and derates linearly to 21 A at TC = 100 °C. Thermal resistance RθJC is 0.95 °C/W, enabling efficient heat transfer to heatsinks in high-power switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 150 V - Maximum blocking voltage for use in 100 V bus systems with 50 % safety margin |
| RDS(on) | 55 mΩ @ VGS = 10 V - Enables <1.0 W conduction loss at 43 A, reducing thermal load in compact designs |
| Qg | 71 nC - Determines gate driver power requirement; compatible with standard 1-A peak drivers |
| EAS | 330 mJ - Supports unclamped inductive switching without external snubbers in relay/motor drive applications |
| trr | 120 ns - Limits cross-conduction losses in synchronous rectification and half-bridge configurations |
| RθJC | 0.95 °C/W - Allows direct mounting to aluminum heatsink with minimal thermal interface resistance |
Pinout & Package
IRF3415SPBF uses the industry-standard TO-220AB package with isolated tab (drain-connected), 3-pin through-hole configuration, and RoHS-compliant matte tin plating on leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output terminal | Electrically connected to metal tab; requires insulating washer when mounted to grounded heatsink |
| Gate | Control electrode for channel modulation | High-impedance input requiring <100 nA leakage current; sensitive to ESD above ±20 V |
| Source | Reference node for gate drive and current return | Common connection point for gate driver ground and load return path in low-side switch topology |
Key Features
| Feature | Design Value |
|---|---|
| 100% avalanche rated | Guarantees reliable operation under inductive load turn-off without external protection components |
| Fast body diode | Reduces reverse recovery losses by 40 % compared to standard MOSFETs in freewheeling paths |
| Enhanced dv/dt capability | Withstands >50 V/ns transient voltage slew rates during hard-switching events |

Applications
| DC-DC Power Supply | Motor Drive |
|---|---|
Use Scenario: Primary-side switch in 12–48 V input, 300 W isolated forward converter. IC Role / Device Role / Timing Role: High-side switching element synchronized to PWM controller at 100–250 kHz. Use Value: Low RDS(on) minimizes conduction loss while fast trr reduces dead-time penalty in transformer reset. | Use Scenario: Low-side switch in 24 V brushed DC motor H-bridge driving 15 A stall current. IC Role / Device Role / Timing Role: Pulse-width modulated power stage with 20 kHz switching frequency and 100 ns minimum off-time.

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 |
|---|---|---|---|
| STP16NF15 | RDS(on) = 90 mΩ @ 10 V; Qg = 45 nC; VDS = 150 V | Higher conduction loss but lower gate drive demand; suited for space-constrained gate driver layouts | Select when gate drive current budget is limited and thermal margin allows higher RDS(on) |
| IXTP44N15P | RDS(on) = 44 mΩ @ 10 V; EAS = 220 mJ; TO-220FP package | Lower RDS(on) but reduced avalanche energy; non-isolated tab requires insulated mounting | Prefer for maximum efficiency in forced-air cooled systems where avalanche stress is minimal |
Compared with STP16NF15 and IXTP44N15P, IRF3415SPBF offers balanced trade-offs: superior avalanche ruggedness over IXTP44N15P and lower conduction loss than STP16NF15, making it optimal for unregulated inductive loads with variable duty cycles.

FAQ
What is the maximum pulsed drain current rating for IRF3415SPBF?
The absolute maximum pulsed drain current (IDM) is 170 A, specified at TC = 25 °C with pulse width ≤ 300 µs and duty cycle ≤ 2 %. This rating applies only under controlled test conditions and must be derated per SOA curves in the official Infineon datasheet DS-IRF3415SPBF-RevB.
Does IRF3415SPBF require a gate resistor for safe operation?
Yes - a gate series resistor (typically 10–47 Ω) is required to dampen ringing caused by gate loop inductance and prevent spurious turn-on due to dv/dt coupling. The value balances switching speed against EMI and shoot-through risk in bridge configurations.
Can IRF3415SPBF be used in parallel configurations?
Yes, but only with matched devices and individual source resistors (0.05–0.1 Ω) to ensure current sharing. Thermal coupling between paralleled units must be minimized, and gate drive traces must be symmetrical to avoid timing skew exceeding 10 ns.
Is the TO-220AB package of IRF3415SPBF electrically isolated?
No - the metal tab is internally connected to the Drain terminal. Electrical isolation from the heatsink requires a mica or ceramic insulator plus shoulder washers, and thermal interface material must not compromise dielectric strength below 2 kV RMS.
