Product details
Overview
IRLZ24PBF from Vishay Siliconix is a logic-level N-channel enhancement-mode power MOSFET in TO-220AB package, rated for 55 V VDS, 15 A continuous drain current at TC = 25 °C, and 0.085 Ω RDS(on) at VGS = 5 V. It features fast switching, repetitive avalanche rating, and low gate charge (Qg = 27 nC), making it suitable for DC-DC converters and motor control circuits.
For engineers reviewing the IRLZ24PBF datasheet, IRLZ24PBF pinout, IRLZ24PBF application, or IRLZ24PBF equivalent, key selection criteria include its logic-level gate drive compatibility with 3.3 V/5 V microcontrollers, low on-resistance at low VGS, robust body diode recovery (trr = 120 ns), and TO-220AB thermal performance (RthJC = 1.7 °C/W).
Technical Context
The IRLZ24PBF employs a planar vertical DMOS structure optimized for low gate threshold (VGS(th) = 1.0–2.0 V) and enhanced safe operating area (SOA) under unclamped inductive switching. Its dynamic dV/dt rating (5.0 V/ns) and specified Qgd/Qgs ratio (17.5/4.5 nC) support stable high-speed switching in hard-switched topologies.
Designed for single-ended switching applications, the device integrates a monolithic body diode with trr = 120 ns and Qrr = 0.9 μC at IF = 15 A, enabling efficient freewheeling in buck regulators and half-bridge gate drivers without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 55 V - Maximum blocking voltage compatible with 48 V bus systems and automotive 36 V transients |
| RDS(on) @ VGS = 5 V | 0.085 Ω - Enables ≤1.3 W conduction loss at 4 A, reducing heatsink requirements |
| ID (continuous, TC = 25 °C) | 15 A - Supports medium-power loads such as 12 V/24 V brushed motor drives |
| Qg | 27 nC - Allows full turn-on with <100 ns gate drive pulse using standard 1 A drivers |
| trr | 120 ns - Limits reverse recovery losses in synchronous rectification and PWM inverters |
| EAS | 250 mJ - Withstands single-pulse inductive energy up to 250 mJ without failure |
| RthJC | 1.7 °C/W - Delivers 50 W power dissipation capability with minimal case-to-sink thermal resistance |
Pinout & Package
IRLZ24PBF uses the industry-standard TO-220AB package with isolated tab (drain-connected), offering mechanical robustness and direct heatsinking capability. The package has 3 leads: Gate (G), Drain (D), Source (S), with pin 1 = Gate, pin 2 = Drain, pin 3 = Source when viewed from front (label side) with leads down.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (Pin 1) | Control electrode | Accepts logic-level input (1.0–2.0 V threshold); requires ≤27 nC total charge for full enhancement |
| Drain (Pin 2) | High-side switch node | Internally connected to metal tab; must be electrically isolated from heatsink unless system ground reference permits |
| Source (Pin 3) | Power return path | Serves as common reference for gate drive; low-inductance layout critical for EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 4.5 V, enabling direct interface with 3.3 V MCU GPIOs without level-shifting |
| Repetitive avalanche rated | Rated for IAR = 15 A and EAR = 12 mJ, supporting reliable operation in inductive load switching without snubbers |
| Low Qgd/Qgs ratio | Ratio of 3.9:1 minimizes Miller-induced shoot-through risk in half-bridge configurations |
| Fast body diode recovery | trr = 120 ns and Qrr = 0.9 μC reduce switching losses during commutation in synchronous rectifiers |
| RoHS-compliant, lead-free | Pb-free termination per JEDEC J-STD-609, qualified to Vishay's MSL Level 1 (unlimited floor life) |
Applications
| Brushed DC Motor Control | DC-DC Synchronous Buck Converter |
|---|---|
Use Scenario: Driving 12 V/24 V brushed motors in industrial actuators with PWM at 20–50 kHz. IC Role / Device Role / Timing Role: Low-side power switch handling bidirectional current up to 15 A peak. Use Value: 0.085 Ω RDS(on) limits I²R loss to <2 W at 15 A, enabling compact PCB layout without forced air cooling. |
Use Scenario: High-efficiency 12 V input to 3.3 V/5 V output buck regulator for FPGA or DSP power rails. IC Role / Device Role / Timing Role: Synchronous rectifier replacing Schottky diode to minimize conduction loss. Use Value: Body diode trr = 120 ns prevents cross-conduction overlap, improving efficiency by ≥3% over diode-based designs. |
| LED Constant-Current Driver | Industrial PLC Output Module |
Use Scenario: High-brightness LED string driver with analog dimming and short-circuit protection. IC Role / Device Role / Timing Role: Series-pass switch modulating current through LED load via linear/PWM control.

Use Scenario: Solid-state relay replacement in programmable logic controller output cards driving solenoids and valves. IC Role / Device Role / Timing Role: Load switch isolating 24 V DC field devices from controller logic. Use Value: VGS(th) = 1.0–2.0 V ensures clean turn-on with PLC output voltages as low as 3.5 V, eliminating false triggering. |
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 |
|---|---|---|---|
| IRFZ24N | RDS(on) = 0.07 Ω @ VGS = 10 V but VGS(th) = 2.0–4.0 V; not logic-level at 3.3 V | Requires 10 V gate drive for optimal RDS(on); unsuitable for direct 3.3 V MCU interface | Select IRLZ24PBF when interfacing with 3.3 V microcontrollers; choose IRFZ24N only if 10 V gate supply is available. |
| STP16NF06L | RDS(on) = 0.07 Ω @ VGS = 5 V, Qg = 22 nC, but VDS = 60 V and trr = 180 ns | Higher VDS margin but slower body diode recovery increases switching loss in high-frequency buck stages | Prefer IRLZ24PBF for >30 kHz PWM where fast trr reduces EMI; STP16NF06L fits lower-frequency, higher-voltage applications. |
Compared with IRFZ24N and STP16NF06L, the IRLZ24PBF uniquely balances logic-level drive, fast body diode recovery, and thermal performance in TO-220AB-making it optimal for space-constrained 3.3 V–5 V controlled power stages requiring <150 ns trr and ≤0.09 Ω RDS(on).

FAQ
What is the maximum continuous drain current for IRLZ24PBF at 100 °C case temperature?
The IRLZ24PBF supports 9.5 A continuous drain current at TC = 100 °C, derived from its linear derating factor of 0.125 W/°C and 50 W PD rating at 25 °C. This value is confirmed in the Absolute Maximum Ratings table of the official Vishay datasheet (S21-1046-Rev. D), ensuring thermal stability in enclosed industrial enclosures without active cooling.
Does IRLZ24PBF have a guaranteed avalanche rating, and what does it cover?
Yes, the IRLZ24PBF is repetitively avalanche rated with IAR = 15 A and EAR = 12 mJ, and single-pulse avalanche energy EAS = 250 mJ. These ratings are validated per JEDEC test conditions (VDD = 55 V, L = 1.0 mH, Rg = 25 Ω) and allow safe operation during inductive load turn-off without external clamping components-critical for motor drive and solenoid control applications using IRLZ24PBF.
Can IRLZ24PBF be used with a 3.3 V microcontroller GPIO without a gate driver?
Yes, the IRLZ24PBF has a gate threshold voltage VGS(th) of 1.0–2.0 V and achieves full enhancement at VGS = 4.5 V. When driven directly by a 3.3 V GPIO capable of sourcing ≥10 mA, it delivers RDS(on) ≤ 0.12 Ω-sufficient for ≤8 A loads. However, for 15 A operation or fast switching (>100 kHz), a dedicated gate driver is recommended to ensure complete turn-on and minimize switching losses in IRLZ24PBF.
What is the thermal resistance from junction to case (RthJC) for IRLZ24PBF?
The junction-to-case thermal resistance RthJC for IRLZ24PBF is 1.7 °C/W, measured from die to the TO-220AB metal tab. This value enables 50 W power dissipation at TJ = 150 °C with TC = 65 °C, supporting high-current operation in thermally constrained environments when mounted to an adequately sized heatsink-verified in Vishay's thermal characterization data for IRLZ24PBF.
Is IRLZ24PBF RoHS-compliant and halogen-free?
Yes, the IRLZ24PBF is RoHS-compliant and halogen-free, meeting JEDEC J-STD-609 Class 1A for moisture sensitivity and IPC/JEDEC J-STD-020D for reflow. Its lead-free terminations and absence of brominated flame retardants are documented in Vishay's material declaration (Doc. #99912) and confirmed on the official product page for IRLZ24PBF at www.vishay.com.
