Product details

Overview

IRLR024PBF from Vishay Siliconix is a logic-level N-channel power MOSFET in DPAK (TO-252) package, rated for 60 V V_DS, 14 A continuous drain current at T_C = 25 °C, and 0.10 Ω R_DS(on) at V_GS = 5 V. It delivers fast switching with 18 nC total gate charge and supports surface-mount applications requiring ruggedized, cost-effective power control in DC-DC converters and motor drives.

For engineers reviewing the IRLR024PBF datasheet, IRLR024PBF pinout, IRLR024PBF application, or IRLR024PBF equivalent, key selection considerations include its logic-level gate drive compatibility (V_GS(th) = 1.0–2.0 V), avalanche energy rating (E_AS = 53 mJ), thermal resistance (R_thJC = 3.0 °C/W), and PCB-mount power dissipation (2.5 W).

Technical Context

This third-generation power MOSFET uses planar V-groove technology to achieve low on-resistance while maintaining high dV/dt immunity (4.5 V/ns peak diode recovery). Its dynamic parameters-including Q_gd = 12 nC and C_iss = 870 pF-are optimized for hard-switched topologies requiring controlled turn-on/turn-off timing.

The device integrates an intrinsic body diode with t_rr = 130–260 ns and Q_rr = 0.75–1.5 μC, enabling reliable freewheeling in synchronous rectification and unclamped inductive switching (IAS = 14 A, E_AS = 53 mJ).

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Maximum blocking voltage for 24–48 V bus applications
R_DS(on) @ V_GS = 5 V	0.10 Ω - Enables <1.4 W conduction loss at 12 A DC load
Q_g	18 nC - Determines gate driver current requirement (~1.8 mA avg. for 100 kHz switching)
I_D (continuous)	14 A @ T_C = 25 °C - Supports high-current loads with minimal heatsinking
R_thJC	3.0 °C/W - Allows direct thermal coupling to PCB copper pour or heatsink
E_AS	53 mJ - Withstands single-pulse inductive energy without failure in motor control
t_r/t_f	110 ns / 41 ns - Enables efficient operation up to ~500 kHz in SMPS designs

Pinout & Package

DPAK (TO-252) package with exposed drain pad for thermal and electrical connection; surface-mount compatible using vapor-phase, infrared, or wave soldering per JEDEC standards.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Logic-level input (1.0–2.0 V threshold); requires <100 nA leakage current handling

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced with 4–5 V MCU GPIO or PWM controller output - no level-shifter needed
Ruggedized dV/dt rating	4.5 V/ns - prevents false turn-on during high-speed switching in noisy industrial environments
Low Q_gd/Q_g ratio	12/18 = 67% - improves Miller immunity and reduces switching losses in hard-switched converters
Integrated body diode	14 A continuous forward current with 1.5 V V_SD - supports bidirectional current in H-bridge and synchronous buck stages
Avalanche-rated	53 mJ single-pulse energy - eliminates need for external snubbers in relay driving and solenoid control

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRLR2905PBF	60 V V_DS, 42 A I_D, 0.035 Ω R_DS(on) @ 5 V - higher current, lower R_DS(on), larger die	Higher power density required; needs stronger gate drive (Q_g = 51 nC)	Choose when >20 A load current or <0.5 W conduction loss is mandatory; verify PCB thermal capacity.
SiHLR024TRL-GE3	Identical electrical specs; lead-free/halogen-free construction; same DPAK package; RoHS-compliant plating	No functional difference - intended for environmentally regulated production	Select for new designs requiring full RoHS/REACH compliance; pin-to-pin and thermal drop-in replacement.

FAQ

What is the maximum junction temperature rating for IRLR024PBF?

The IRLR024PBF has an operating junction and storage temperature range of –55 °C to +150 °C. This allows reliable operation in under-hood automotive environments and industrial enclosures with ambient temperatures up to 85 °C when properly heatsinked. The device's thermal resistance (R_thJC = 3.0 °C/W) enables effective junction temperature control even at full 14 A continuous current.

Does IRLR024PBF require a gate resistor for typical 5 V microcontroller drive?

Yes - a gate resistor is recommended for IRLR024PBF to control dv/dt and prevent ringing. While the device is logic-level (V_GS(th) = 1.0–2.0 V), its Q_g = 18 nC and Q_gd = 12 nC make it sensitive to parasitic oscillation. A 10–25 Ω series gate resistor balances switching speed and stability, especially when driven by low-impedance MCU outputs or dedicated gate drivers.

Can IRLR024PBF be used in avalanche mode repeatedly?

No - IRLR024PBF is rated for single-pulse avalanche energy only (E_AS = 53 mJ). Repetitive avalanche operation is not characterized or guaranteed. For applications involving frequent inductive switching (e.g., relay coils or solenoids), external clamping (TVS or RCD snubber) is required to limit V_DS stress below 60 V and avoid cumulative junction damage.

What is the body diode forward voltage of IRLR024PBF at 14 A?

The body diode forward voltage (V_SD) of IRLR024PBF is specified as 1.5 V maximum at T_J = 25 °C and I_S = 14 A with V_GS = 0 V. This value increases with junction temperature - expect ~1.7 V at 100 °C - and must be accounted for in freewheeling loss calculations in half-bridge or synchronous rectifier configurations.

Is IRLR024PBF pin-compatible with IRLU024PbF?

No - IRLR024PBF uses DPAK (TO-252) surface-mount packaging with three leads (G-D-S), while IRLU024PbF uses IPAK (TO-251) through-hole packaging with straight leads and identical pinout orientation but different mechanical footprint and thermal mounting. PCB layout and assembly process are not interchangeable; redesign is required for substitution.
