Product details
Overview
IRF9Z24SPBF from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, rated for -60 V drain-source voltage, 0.28 Ω on-resistance at -10 V gate drive, and -11 A continuous drain current at 25 °C. It delivers fast switching, full avalanche ruggedness, and 175 °C junction operation for high-reliability DC-DC converters and motor control circuits.
For engineers reviewing the IRF9Z24SPBF datasheet, IRF9Z24SPBF pinout, IRF9Z24SPBF application, or IRF9Z24SPBF equivalent, key selection criteria include its -60 V VDS, 0.28 Ω RDS(on), 19 nC total gate charge, D2PAK thermal performance (RthJC = 2.5 °C/W), and body diode recovery characteristics (trr = 100–200 ns).
Technical Context
This device uses Vishay's third-generation silicon process to achieve low on-resistance per die area while maintaining robust avalanche capability (EAS = 240 mJ). Its P-channel architecture enables high-side switching without level-shifting circuitry in buck regulators and load switches.
The D2PAK package provides low thermal resistance (RthJC = 2.5 °C/W) and high power dissipation (60 W at TC = 25 °C), supporting high-current applications where PCB-mount thermal management is critical. The integral body diode supports synchronous rectification and flyback energy recovery in inductive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -60 V - Supports input rails up to 48 V DC systems with margin for transients |
| RDS(on) @ VGS = -10 V | 0.28 Ω - Enables <1.0 W conduction loss at -6.6 A, reducing heatsink requirements |
| Qg (total) | 19 nC - Determines gate driver strength needed for <100 ns switching transitions |
| ID (continuous) | -11 A @ TC = 25 °C - Sustains steady-state load current in high-side switch configurations |
| EAS | 240 mJ - Withstands unclamped inductive energy during fault conditions without failure |
| trr (body diode) | 100–200 ns - Limits reverse recovery losses in hard-switched topologies |
| TJ max | +175 °C - Allows operation in sealed enclosures or high-ambient industrial environments |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-terminal configuration (Drain, Gate, Source); standard JEDEC outline with 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / heat sink interface | Electrically and thermally connected to large copper pad; must be soldered to PCB ground plane or heatsink for RthJC = 2.5 °C/W performance |
| Gate | Control terminal for channel modulation | Requires negative VGS (≤ -2.0 V threshold) to turn on; sensitive to ESD; driven via low-impedance source due to 19 nC Qg |
| Source | Reference node for gate drive and current return | Connected to system ground or floating rail; defines VGS reference; carries full load current (-11 A) |
Key Features
| Feature | Design Value |
|---|---|
| Fully avalanche rated | 240 mJ single-pulse energy handling ensures robustness against inductive kickback without external snubbers |
| 175 °C maximum junction temperature | Enables deployment in automotive under-hood or industrial motor drive environments without derating |
| Fast switching (td(on) = 13 ns, tf = 29 ns) | Reduces switching losses in high-frequency DC-DC converters (>100 kHz) and PWM motor drivers |
| Low RDS(on) × Qg figure of merit (5.32 Ω·nC) | Optimizes trade-off between conduction and switching loss for medium-power SMPS designs |
| Surface-mount D2PAK package | Delivers 60 W power dissipation in compact footprint-higher than TO-220 while enabling automated assembly |
Applications
| High-Side Load Switch | Buck Converter High-Side Switch |
|---|---|
Use Scenario: Power sequencing and hot-swap control in telecom line cards and server PSUs. IC Role / Device Role / Timing Role: P-channel MOSFET configured as high-side switch with gate driven by simple inverting logic or dedicated load switch controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF9Z34NPBF | -60 V VDS, 0.20 Ω RDS(on), 17 nC Qg, TO-220 package | Lower RDS(on) but higher RthJA (62 °C/W vs. 40 °C/W); no D2PAK thermal pad | Prefer when board space allows TO-220 and lower conduction loss outweighs thermal advantage of D2PAK |
| SiHF9Z24STRL-GE3 | Identical silicon and specs; RoHS-compliant, halogen-free, tape-and-reel packaging | No functional difference; optimized for automated SMT production with Pb-free finish | Select when lead-free compliance and volume reel delivery are required; same thermal and electrical behavior as IRF9Z24SPBF |
Compared with IRF9Z24SPBF, IRF9Z34NPBF offers lower on-resistance but sacrifices thermal performance and surface-mount compatibility, while SiHF9Z24STRL-GE3 provides identical electrical behavior with enhanced environmental compliance and packaging for high-volume manufacturing.

FAQ
What is the maximum continuous drain current for IRF9Z24SPBF at 100 °C case temperature?
The IRF9Z24SPBF supports -7.7 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package and ensures safe operation within its 175 °C maximum junction temperature. Designers must verify PCB copper area and airflow to maintain TC ≤ 100 °C under full load. The IRF9Z24SPBF datasheet confirms this value under "Continuous Drain Current" with footnote "TC = 100 °C".
Does IRF9Z24SPBF have a built-in body diode, and what are its key parameters?
Yes, the IRF9Z24SPBF integrates a body diode inherent to its vertical P-channel MOSFET structure. Key parameters include -11 A continuous forward current (IS), -6.3 V forward voltage (VSD) at -11 A and 25 °C, and 100–200 ns reverse recovery time (trr). These values are measured with VGS = 0 V and enable use in freewheeling and clamping roles. The IRF9Z24SPBF body diode is fully characterized in the "Drain-Source Body Diode Characteristics" section of its datasheet.
What is the gate threshold voltage range for IRF9Z24SPBF, and how does it affect drive requirements?
The IRF9Z24SPBF has a gate threshold voltage (VGS(th)) range of -2.0 V to -4.0 V at ID = -250 μA, meaning it begins conducting significantly between those voltages. Full enhancement requires VGS ≤ -10 V to achieve RDS(on) = 0.28 Ω. This negative threshold mandates a negative gate drive relative to the source, making it suitable for high-side configurations with simple inverting drivers. The IRF9Z24SPBF specification sheet lists this in the "Static" subsection under "Gate-Source Threshold Voltage".
Can IRF9Z24SPBF be used in avalanche mode, and what is its rated single-pulse energy?
Yes, the IRF9Z24SPBF is fully avalanche rated with a single-pulse avalanche energy (EAS) of 240 mJ under test conditions of VDD = -25 V, starting TJ = 25 °C, L = 2.3 mH, Rg = 25 Ω, and IAS = -11 A. This rating allows safe operation during inductive switching events without external protection. The IRF9Z24SPBF datasheet explicitly states "Fully avalanche rated" in Features and provides EAS in Absolute Maximum Ratings.
What is the thermal resistance from junction to case (RthJC) for IRF9Z24SPBF, and why is it important?
The IRF9Z24SPBF has a maximum junction-to-case thermal resistance (RthJC) of 2.5 °C/W, measured from the silicon die to the exposed drain tab. This low value enables efficient heat transfer to an external heatsink or PCB copper plane, supporting up to 60 W power dissipation at TC = 25 °C. Accurate thermal design using RthJC is essential to prevent exceeding the 175 °C maximum junction temperature. The IRF9Z24SPBF Thermal Resistance Ratings table specifies this parameter under "Maximum Junction-to-Case (Drain)".
