Product details
Overview
IRFZ24SPBF from Vishay Siliconix is a 60 V, 17 A N-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, featuring 0.10 Ω RDS(on) at VGS = 10 V, 25 nC total gate charge, and 175 °C maximum junction temperature. It serves as a high-current switching element in DC-DC converters, motor drivers, and power supply synchronous rectification circuits.
For engineers reviewing the IRFZ24SPBF datasheet, IRFZ24SPBF pinout, IRFZ24SPBF application, or IRFZ24SPBF equivalent, key selection criteria include its 60 V VDS, 17 A continuous drain current at TC = 25 °C, fast 13 ns turn-on delay, low 2.5 °C/W junction-to-case thermal resistance, and surface-mount D2PAK packaging for high-power density designs.
Technical Context
This MOSFET employs third-generation silicon process technology to achieve low on-resistance per die area while maintaining rugged avalanche capability (100 mJ single-pulse). Its gate threshold voltage range of 2.0–4.0 V ensures reliable turn-on with standard 10 V logic-level drive.
The device integrates a fast-recovery body diode with 88–180 ns reverse recovery time and 0.29–0.64 nC Qrr, enabling efficient operation in hard-switched topologies. Thermal design is supported by a 2.5 °C/W RthJC and compatibility with PCB-mounted heatsinking via the exposed drain pad.

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 | Same silicon die, TO-220 package; higher RthJA (62 °C/W vs. 40 °C/W), no exposed thermal pad | Requires through-hole assembly and external heatsink; unsuitable for high-density SMT layouts | Select IRFZ24SPBF for surface-mount, thermally constrained, or automated production environments |
| SiHFZ24S-GE3 | Identical D2PAK package and electrical specs; RoHS-compliant, halogen-free construction | No functional difference; preferred for environmentally regulated end equipment (e.g., EU medical, industrial) | Choose SiHFZ24S-GE3 when RoHS/halogen-free compliance is mandatory per BOM requirements |
Compared with IRFZ24N and SiHFZ24S-GE3, the IRFZ24SPBF offers identical electrical performance in a Pb-free D2PAK package optimized for thermal transfer and SMT manufacturability-making it ideal for space-constrained, high-reliability power stages where board area and thermal resistance are critical.

FAQ
What is the maximum continuous drain current rating for IRFZ24SPBF at 100 °C case temperature?
The IRFZ24SPBF supports 12 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating from 17 A at 25 °C reflects thermal limitations of the D2PAK package and must be applied in thermally constrained layouts without active cooling.
Does IRFZ24SPBF require a gate resistor for safe switching in a 48 V motor drive application?
Yes, IRFZ24SPBF benefits from an external gate resistor to control dV/dt and prevent oscillation. With 25 nC total gate charge and fast 13 ns turn-on delay, a 10–25 Ω resistor is typical to limit peak gate current and damp ringing-especially when driving inductive loads like motors where voltage overshoot must be contained.
Is IRFZ24SPBF pin-compatible with IRFZ24N?
No, IRFZ24SPBF is not pin-compatible with IRFZ24N. IRFZ24SPBF uses the D2PAK (TO-263) surface-mount package with G-D-S pinout on a gull-wing leadframe, while IRFZ24N uses the through-hole TO-220AB package with different mechanical footprint and thermal pad layout-requiring PCB redesign for substitution.
What is the body diode forward voltage of IRFZ24SPBF at 17 A and 25 °C?
The body diode forward voltage (VSD) of IRFZ24SPBF is 1.5 V at TJ = 25 °C and IS = 17 A with VGS = 0 V, as measured per the Diode Characteristics section. This value increases with junction temperature and must be considered in freewheeling path loss calculations.
Can IRFZ24SPBF be used in avalanche-rated circuits without external protection?
Yes, IRFZ24SPBF is rated for 100 mJ single-pulse avalanche energy (EAS) under defined test conditions (VDD = 25 V, L = 400 μH, IAS = 17 A). It can safely absorb inductive energy in controlled unclamped scenarios-such as relay coil snubbing-but repetitive avalanche requires careful thermal and pulse-width management per Figure 12c.
