Vishay Siliconix IRLR024

Overview

IRLR024 from Vishay Siliconix is a logic-level N-channel power MOSFET in DPAK (TO-252) surface-mount 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 unclamped inductive switching up to 53 mJ, making it suitable for DC-DC converters and motor control circuits.

For engineers reviewing the IRLR024 datasheet, IRLR024 pinout, IRLR024 application, or IRLR024 equivalent, this page provides verified electrical parameters, thermal resistance values (R_thJC = 3.0 °C/W), body diode recovery characteristics (t_rr = 130–260 ns), and validated alternative part options for industrial power switching designs.

Technical Context

The IRLR024 employs third-generation trench MOSFET technology optimized for low conduction loss and high dV/dt immunity. Its gate threshold voltage (1.0–2.0 V) enables direct drive from 3.3 V or 5 V logic, while its dynamic dV/dt rating of 4.5 V/ns ensures robust operation in noisy switching environments.

Designed for PCB-mount thermal performance, the device achieves 2.5 W maximum power dissipation on a 1" square FR-4 board and supports avalanche energy handling (E_AS = 53 mJ) without external snubbers-critical for flyback and H-bridge topologies where inductive load transients occur.

FAQ

What is the maximum continuous drain current rating for IRLR024 at 100 °C case temperature?

The IRLR024 supports 9.2 A continuous drain current at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the DPAK package and assumes proper PCB copper area for heat spreading. At T_C = 25 °C, the rating increases to 14 A, with linear derating at 0.33 W/°C between those points. The IRLR024 datasheet confirms this value under standard test conditions with no additional heatsinking.

Does IRLR024 require a gate resistor for safe operation in switching applications?

Yes, the IRLR024 benefits from an external gate resistor to control dI/dt and suppress ringing caused by parasitic inductance in the gate loop. While not strictly mandatory for low-frequency on/off use, Vishay recommends R_g = 9.0 Ω for standardized switching characterization (td(on) = 11 ns, tr = 110 ns). For 100–500 kHz PWM, a 5–22 Ω resistor balances switching speed against EMI and shoot-through risk. The IRLR024 gate capacitance (C_iss = 870 pF) makes gate drive impedance critical to timing consistency.

Can IRLR024 be used in avalanche mode repeatedly, and what is its rated energy?

Yes, the IRLR024 is rated for repetitive avalanche operation with a single-pulse avalanche energy (E_AS) of 53 mJ under defined test conditions (V_DD = 25 V, I_AS = 14 A, T_J = 25 °C). This capability is built into the device's ruggedized trench structure and allows safe operation in inductive switching without external snubbers. However, repetitive avalanche must respect pulse width and duty cycle limits per Figure 11 to avoid exceeding T_J(max) = 150 °C. The IRLR024 datasheet explicitly validates this rating.

What is the body diode forward voltage of IRLR024, and how does it affect synchronous rectification?

The IRLR024 body diode forward voltage (V_SD) is 1.5 V at T_J = 25 °C and I_S = 14 A with V_GS = 0 V. In synchronous rectification, this V_F determines conduction loss before the MOSFET channel turns on. Because the IRLR024 has relatively high V_SD compared to Schottky diodes (~0.5 V), it is best deployed where its low R_DS(on) advantage outweighs body diode loss-typically in high-current (>5 A), medium-frequency (>100 kHz) buck converters where channel conduction dominates total loss. The IRLR024 body diode recovery time (t_rr = 130–260 ns) also impacts reverse recovery loss during dead-time transitions.

Is IRLR024 pin-compatible with IRLU024, and what is the key mechanical difference?

No, IRLR024 is not pin-compatible with IRLU024. The IRLR024 uses a DPAK (TO-252) surface-mount package with gull-wing leads and an exposed drain pad, while the IRLU024 uses an IPAK (TO-251) through-hole package with straight leads and no thermal pad. Although both share identical silicon die and electrical specifications (V_DS = 60 V, R_DS(on) = 0.10 Ω, Q_g = 18 nC), their footprints, soldering methods, and thermal mounting approaches differ fundamentally. Substituting IRLR024 for IRLU024 requires PCB redesign. The IRLR024 datasheet explicitly distinguishes these variants in the Ordering Information table.
