Typical Applications
IRL1404ZSTRLPBF is suitable for 6 applications: High-Current DC Motor Drive, 12 V Battery Protection & Load Switching, Synchronous-Rectifier Low-Side Switch in Buck Converter, Hot-Swap / Inrush Current Limiter on 12 V Backplanes, High-Power LED Driver / PWM Dimming, Automotive ECU High-Side/Low-Side Switching.
High-Current DC Motor Drive
The IRL1404ZSTRLPBF's 200 A continuous rating and 3.1 mΩ RDS(on) make it a strong fit for brushed-DC and low-voltage BLDC motor drive stages in 12 V and 24 V systems. With VGS(th) in the 1.0–2.0 V range and full enhancement at 4.5 V, a 5 V MCU or a small gate driver such as TC4420 can switch it directly, eliminating the need for a 10 V supply. Conduction loss at 30 A is roughly I²R = 30² × 0.0031 = 2.8 W, easily handled by the D2PAK on a 1 oz copper pour. Designers should add a flyback diode across inductive loads and respect the SOA during stall-current transients, where the device may briefly see full battery voltage across the drain.
Recommended
12 V Battery Protection & Load Switching
In 12 V lead-acid and 3–4S Li-ion battery packs, the IRL1404ZSTRLPBF serves as a low-side disconnect switch or reverse-polarity protector. Its 40 V VDS comfortably handles 12 V nominal with 40 V load-dump transients clamped externally, and the 3.1 mΩ RDS(on) limits steady-state voltage drop to about 15 mV at 5 A - small enough to avoid nuisance under-voltage trips. Logic-level drive allows the BMS microcontroller to control the FET directly without a charge pump. For multi-cell packs, two IRL1404ZSTRLPBF in back-to-back configuration provide true bidirectional isolation. Thermal design should assume worst-case sustained current and verify Tj stays below 125 °C using the D2PAK tab soldered to a 1–2 square inch copper pour.
Recommended
Synchronous-Rectifier Low-Side Switch in Buck Converter
As a low-side synchronous rectifier in a 12 V-input buck converter, the IRL1404ZSTRLPBF delivers low conduction loss thanks to 3.1 mΩ RDS(on) and moderate switching loss with 75 nC Qg. At 100 kHz and 20 A output, total losses are roughly 1.2 W conduction plus 0.15 W gate drive, enabling fanless designs up to 25 A. The logic-level threshold allows direct drive from a synchronous-rectifier controller such as IR2110 or IRS2181 without a charge pump. Above 300 kHz the Qg-related switching loss starts to dominate, and a part like BSZ0901NS becomes preferable. Always cross-check the SOA at startup when the high-side FET first closes and the low-side FET body-diode recovery current flows.
Recommended
Hot-Swap / Inrush Current Limiter on 12 V Backplanes
In 12 V hot-swap controllers, the IRL1404ZSTRLPBF acts as the main pass element limiting inrush into bulk capacitors. Its 3.1 mΩ RDS(on) keeps steady-state drop below 30 mV at 10 A, while the 40 V VDS rating tolerates transient overshoots from inductive backplane traces. Logic-level drive lets a hot-swap controller IC such as LM5069 or LTC4217 control the gate directly. During a short-circuit event, the SOA must be respected: the part can sustain roughly 100 A at 20 V for milliseconds, but must be de-rated for sustained faults. Pairing it with a current-sense amplifier and a TVS clamp on the drain provides robust fault handling.
Recommended
High-Power LED Driver / PWM Dimming
For high-power LED arrays such as automotive headlamps or architectural lighting, the IRL1404ZSTRLPBF can be used as a low-side PWM switch to drive strings of 1–3 W LEDs at several amps per channel. Its 200 A current rating and 3.1 mΩ RDS(on) keep conduction losses negligible, while the logic-level gate threshold allows direct PWM from a 5 V microcontroller at dimming frequencies from 100 Hz to several kHz without flicker. The 75 nC Qg supports dimming up to about 50 kHz before driver-stage losses become significant. PCB thermal design is critical - at 5 A continuous the dissipation is 0.077 W, but in a fault condition with all LED current through one FET, derating must be applied.
Recommended
Automotive ECU High-Side/Low-Side Switching
Within 12 V automotive ECUs, the IRL1404ZSTRLPBF can switch solenoids, relays, lamps, and small motors directly. Its 40 V rating comfortably handles 12 V nominal plus load-dump transients when protected by a TVS clamp, and the logic-level threshold allows direct drive from 5 V ECU microcontrollers. For automotive applications requiring AEC-Q101 qualification, the AUIRL1404ZSTRL variant is the recommended part - same die, same package, same pinout, just automotive-screened. Designers should add reverse-battery protection (a P-FET or Schottky diode) and respect ISO 7637-2 transient immunity requirements. D2PAK thermal performance is sufficient for most ECU-mounted actuators under 20 A.

Key Differentiators
- True logic-level drive at 4.5 V VGS with very low RDS(on) (vs IRFB3004PBF)
- Lowest Qg among 40 V/200 A class D2PAK logic-level parts (vs IRLB3034PBF)
- Same die available in AEC-Q101 automotive grade (vs AUIRL1404ZSTRL)
Design Notes
At 50 A continuous and RDS(on) = 3.1 mΩ, conduction loss is approximately I²R = 50² × 0.0031 = 7.75 W, raising the D2PAK junction temperature by roughly 7.75 W × 40 °C/W = 310 °C above the tab without adequate copper. Estimated: this assumes 40 °C/W theta_JC + theta_CS + PCB. The D2PAK tab must be soldered to at least 1–2 square inches of 2 oz copper to keep Tj below 150 °C at 25 A continuous; above 50 A, a forced-air or heatsink attached to the tab is required.
Use a single solid copper pad under the D2PAK tab, not thermal vias alone, to maximize heat spreading into inner PCB layers. Stitch the source pin (pin 3) with multiple vias into a continuous ground plane to minimize source-inductance-induced ringing at the gate. Place the gate-drive resistor (typically 10–47 Ω) within 5 mm of pin 1 to suppress parasitic oscillation, especially when driving long gate traces or in high-dV/dt applications.
Do not parallel multiple IRL1404ZSTRLPBF devices without gate-source resistors on each individual device - mismatched RDS(on) and threshold voltages can force one FET to carry all the current until it thermally runs away. For parallel operation, use individual 10–100 Ω gate resistors and ensure all devices share a common, low-impedance heat sink. Also avoid exceeding VGS = ±16 V (datasheet limit) by clamping the gate with a 12 V Zener when using a 15 V or higher gate driver.
Compliance Information
RoHS compliant and lead-free (PBF suffix per Infineon datasheet). Not AEC-Q100 qualified; choose AUIRL1404ZSTRL for automotive applications. Halogen-free and conflict-minerals compliant per Infineon product environmental compliance statements.
