Product details
Overview
IRLZ24NPBF from Infineon Technologies is a 55 V, 30 A, logic-level N-channel HEXFET power MOSFET in TO-220AB package, featuring RDS(on) = 40 mΩ at VGS = 10 V and 50 mΩ at VGS = 5 V, optimized for DC-DC converters and motor control switches.
For engineers reviewing the IRLZ24NPBF datasheet, IRLZ24NPBF pinout, IRLZ24NPBF application, or IRLZ24NPBF equivalent, key selection criteria include gate threshold voltage (VGS(th) = 1.0–2.0 V), continuous drain current rating, thermal resistance (RθJC = 1.7 °C/W), and lead-free compliance per JEDEC TO-220AB outline.
Technical Context
This MOSFET uses planar silicon process with optimized channel geometry to achieve low on-resistance while maintaining robust avalanche capability (EAS = 190 mJ). Its logic-level gate drive enables direct interface with 3.3 V and 5 V microcontrollers without level-shifting circuitry.
The device operates in enhancement mode with zero gate current requirement, supporting high-efficiency switching in hard-switched topologies up to 100 kHz. Thermal design leverages the TO-220AB package's exposed drain tab for direct heatsink mounting and low junction-to-case thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum drain-source blocking voltage for 24 V industrial bus and automotive load-switch applications. |
| ID (continuous) | 30 A @ TC = 25 °C - Sustains full-load current in motor drivers and solenoid drivers with adequate heatsinking. |
| RDS(on) | 50 mΩ @ VGS = 5 V - Enables efficient operation directly from 5 V logic outputs, reducing gate driver complexity. |
| VGS(th) | 1.0–2.0 V - Ensures reliable turn-on with standard CMOS/TTL logic levels and low-power MCU GPIOs. |
| EAS | 190 mJ - Supports unclamped inductive switching in relay and motor coil driving without external snubbers. |
| RθJC | 1.7 °C/W - Allows calculation of junction temperature rise under conduction loss, critical for thermal margin validation. |
Pinout & Package
IRLZ24NPBF is housed in a through-hole TO-220AB package with an electrically isolated metal tab (drain-connected) for mechanical mounting and thermal dissipation. The package complies with JEDEC standard outline and supports lead-free reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives voltage-controlled signal to modulate channel conductivity; high input impedance minimizes drive current demand. |
| 2 (Drain) | High-side power terminal | Connected to load supply rail; electrically tied to metal tab for thermal path and requires isolation from heatsink unless referenced to same potential. |
| 3 (Source) | Reference terminal | Serves as return path for load current and reference node for gate drive; defines common source configuration in low-side switch topology. |
| 4 (Drain) | Secondary drain connection | Parallel drain path to Pin 2, reducing package inductance and improving current sharing in high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 5 V, eliminating need for gate driver ICs in 5 V control systems. |
| Low RDS(on) at 5 V | 50 mΩ ensures <1.5 W conduction loss at 30 A, enabling compact thermal design in space-constrained PCBs. |
| 100% avalanche rated | Guaranteed EAS = 190 mJ allows safe operation in inductive load switching without external protection components. |
| Lead-free and RoHS compliant | Meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 and EU RoHS Directive 2011/65/EU requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLZ44NPBF | RDS(on) = 25 mΩ @ 5 V; higher gate charge (Qg = 44 nC vs. 32 nC); same TO-220AB package. | Better efficiency at high current but slower switching; suited for lower-frequency, higher-current DC-DC stages. | Choose when conduction loss dominates over switching loss and gate drive strength permits higher Qg. |
| STP30NF20 | VDS = 200 V; RDS(on) = 45 mΩ @ 10 V only; not logic-level (VGS(th) = 2.0–4.0 V); TO-220FP package. | Requires 10 V gate drive; suitable for higher-voltage AC-DC PFC or universal input SMPS where 55 V is insufficient. | Select only if system voltage exceeds 55 V and gate driver supports ≥10 V output. |
Compared with IRLZ44NPBF, the IRLZ24NPBF offers lower gate charge for faster switching at moderate current, while STP30NF20 trades logic-level compatibility for higher voltage rating-making IRLZ24NPBF optimal for cost-sensitive, 24–36 V embedded power switching where gate drive simplicity is critical.

FAQ
What is the maximum junction temperature for IRLZ24NPBF?
The absolute maximum junction temperature is 175 °C. Derating is required above 25 °C ambient; thermal design must ensure TJ ≤ 175 °C under worst-case conduction and switching losses, using RθJC = 1.7 °C/W and board-level RθCA values from layout testing.
Can IRLZ24NPBF be used in parallel configurations?
Yes, IRLZ24NPBF supports paralleling due to its positive temperature coefficient of RDS(on), which promotes current sharing. Use matched gate resistors (≤10 Ω) and symmetrical PCB layout to minimize loop inductance and ensure balanced dynamic current distribution.
Does IRLZ24NPBF require a gate resistor in 5 V MCU-driven applications?
A gate resistor (10–47 Ω) is recommended to dampen ringing and limit peak gate current during fast transitions. While not strictly required for turn-on, it prevents oscillation and EMI in layouts with >2 cm gate trace length or shared ground paths.
Is the metal tab of IRLZ24NPBF electrically isolated?
No-the metal tab is internally connected to the drain (Pin 2 and Pin 4). Electrical isolation from the heatsink is mandatory unless the heatsink is referenced to the drain potential. Use insulating shoulder washers and silicone thermal pads rated for ≥500 V isolation.
