Product details
Overview
IRFR024NTRR from Infineon Technologies (formerly International Rectifier) is a 55V, 17A N-channel enhancement-mode power MOSFET in TO-252AA (D-Pak) surface-mount package, featuring 0.075Ω RDS(on) at VGS = 10V, 100% avalanche-rated operation, and fast switching with 4.9ns turn-on delay and 27ns fall time. It serves as a high-efficiency synchronous rectifier or load switch in DC-DC converters and motor drive half-bridges.
For engineers reviewing the IRFR024NTRR datasheet, IRFR024NTRR pinout, IRFR024NTRR application, or IRFR024NTRR equivalent, key selection criteria include its 55V VDS, 0.075Ω on-resistance at 10V gate drive, 71mJ single-pulse avalanche energy, TO-252AA thermal resistance (3.3°C/W junction-to-case), and body diode reverse recovery performance (56–83ns trr, 120–180nC Qrr).
Technical Context
This fifth-generation HEXFET device uses advanced planar processing to minimize conduction loss while maintaining rugged unclamped inductive switching capability. Its gate charge profile (Qg = 20nC, Qgd = 7.6nC) supports efficient high-frequency PWM control up to several hundred kHz in buck and half-bridge topologies.
The integrated body diode exhibits low forward voltage (1.3V at 10A, TJ = 25°C) and controlled reverse recovery (dv/dt rating of 5.0V/ns), enabling reliable operation in freewheeling paths without external snubbers in moderate-speed switching applications.

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 |
|---|---|---|---|
| STP16NF55 | 55V VDS, 16A ID, 0.085Ω RDS(on), TO-220 package | Through-hole mounting; higher RθJA (62.5°C/W) limits power density | Preferred where manual assembly or legacy board layout requires through-hole footprint |
| DMN601DWK-7 | 60V VDS, 10A ID, 0.095Ω RDS(on), SOT-26 package | Smaller footprint but lower current rating and no avalanche rating | Suitable only for space-constrained <10A applications without inductive stress |
Compared with STP16NF55 and DMN601DWK-7, IRFR024NTRR delivers superior thermal performance via TO-252AA's 3.3°C/W RθJC, higher avalanche robustness (71mJ vs. none specified), and lower on-resistance-making it optimal for high-reliability, high-current surface-mount power stages.

FAQ
What is the maximum continuous drain current for IRFR024NTRR at 100°C case temperature?
The maximum continuous drain current is 12A at TC = 100°C with VGS = 10V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-252AA package when ambient or board-level cooling is constrained, and must be verified against actual PCB copper area and airflow conditions.
Does IRFR024NTRR require a gate resistor for safe operation?
A gate resistor (typically 10–24Ω) is recommended to dampen ringing and control dv/dt during switching transitions. The device's 7.6nC Miller charge and 20nC total gate charge make it susceptible to oscillation without proper gate drive impedance, especially in high-frequency or high-di/dt applications like motor inverters.
Can IRFR024NTRR be used in linear (analog) mode operation?
No-IRFR024NTRR is not characterized or guaranteed for linear-mode operation. Its Safe Operating Area (SOA) curve shows limited capability beyond 10µs pulse width at high VDS, and sustained linear operation risks thermal runaway due to positive temperature coefficient of RDS(on) and lack of SOA derating data beyond pulsed conditions.
What is the body diode forward voltage specification under typical operating conditions?
The body diode forward voltage is 1.3V maximum at IS = 10A, TJ = 25°C, and VGS = 0V. This value increases with junction temperature and decreases slightly at lower currents; at 1A and 25°C, it measures approximately 0.95V per typical characterization curves in the datasheet.
