Product details
Overview
IRF9520NPBF from Infineon Technologies is a P-channel enhancement-mode MOSFET in TO-220AB package, rated for −100 V VDS, −12 A ID (continuous), and 0.28 Ω RDS(on) at VGS = −10 V. It serves as a high-side load switch or DC-DC synchronous rectifier in industrial power supplies and motor control circuits.
For engineers reviewing the IRF9520NPBF datasheet, IRF9520NPBF pinout, IRF9520NPBF application, or IRF9520NPBF equivalent, key selection criteria include its −100 V blocking capability, low gate charge (QG = 47 nC), avalanche-rated ruggedness (EAS = 230 mJ), and thermal resistance (RθJC = 1.3 °C/W) for reliable conduction under pulsed loads.
Technical Context
This MOSFET uses planar silicon HEXFET technology with optimized channel geometry to achieve stable RDS(on) over temperature (±20% variation from −55 °C to 175 °C). Its gate threshold voltage (VGS(th)) ranges from −2.0 V to −4.0 V, enabling direct logic-level drive from −5 V microcontroller outputs.
The device features integrated body diode with reverse recovery time trr = 140 ns and Qrr = 120 nC at IF = −12 A, supporting hard-switched flyback and buck topologies without external snubbing. Its SOA is defined up to 10 ms single-pulse operation at TC = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | −100 V - supports 80 V DC bus designs with 25% safety margin |
| RDS(on) @ VGS = −10 V | 0.28 Ω - delivers ≤4 W conduction loss at −12 A continuous current |
| ID (continuous) | −12 A @ TC = 25 °C - enables compact heatsink sizing in 100 W power stages |
| QG | 47 nC - allows efficient gate driving with ≤1 W peak driver power at 100 kHz |
| EAS | 230 mJ - withstands inductive turn-off energy without failure in relay drivers |
| RθJC | 1.3 °C/W - limits junction rise to ≤170 °C under 12 A/0.28 Ω dissipation at 25 °C case |
| tr/tf | 35 ns / 80 ns - supports ≤500 kHz switching with minimal overlap loss |
Pinout & Package
IRF9520NPBF is housed in a through-hole TO-220AB package with isolated tab (drain-connected), rated for 175 °C maximum junction temperature and 2.5 kV isolation test voltage. Mounting requires mechanical torque ≤0.5 N·m and thermal interface material with ≤0.5 °C·in²/W resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Accepts −10 V to 0 V logic signal; input capacitance Ciss = 1200 pF limits slew rate |
| 2 (Drain) | High-side power terminal | Connected to heat sink; carries full load current and withstands −100 V transients |
| 3 (Source) | Reference node | Provides return path for gate drive and load current; referenced to system ground in high-side configuration |
| 4 (Drain) | Secondary drain connection | Parallel path to Pin 2 for reduced lead inductance in high-di/dt applications |
Key Features
| Feature | Design Value |
|---|---|
| 100% avalanche tested | Every unit validated to 230 mJ single-pulse energy, eliminating need for external clamping in inductive loads |
| Low gate charge | 47 nC total charge enables use of low-power gate drivers (e.g., TC4427) without boost circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP9PF10 | VDS = −100 V, RDS(on) = 0.35 Ω @ −10 V, QG = 32 nC | Lower gate charge but higher on-resistance increases conduction loss by 25% | Preferred where gate drive power is constrained but thermal margin is available |
| IXTP12P10P | VDS = −100 V, RDS(on) = 0.22 Ω @ −10 V, QG = 62 nC | Lower RDS(on) improves efficiency but higher QG demands stronger gate driver | Selected when minimizing I²R loss dominates over driver complexity |
Compared with STP9PF10 and IXTP12P10P, IRF9520NPBF offers balanced trade-off between gate drive simplicity (47 nC), conduction loss (0.28 Ω), and ruggedness (230 mJ EAS IRF9520NPBF is available at Aetrix Electronics and suitable for industrial power supplies, motor control H-bridges, DC-DC buck converters, and relay driver circuits requiring stable component supply across multi-year production cycles. Supply support for IRF9520NPBF includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs. Infineon Technologies is a German semiconductor manufacturer specializing in power management, automotive ICs, and industrial control solutions, with global manufacturing and quality certification to ISO/TS 16949 and IECQ QC 080000. IRF9520NPBF belongs to the HEXFET® P-channel power MOSFET product line, engineered for high-reliability switching in harsh-environment industrial power conversion and protection systems. The absolute maximum junction temperature is 175 °C, with derated continuous current above 25 °C case temperature per the SOA curve. At TC = 100 °C, maximum continuous ID drops to −6.5 A to maintain RDS(on) stability and avoid thermal runaway. No - its VGS(th) minimum is −2.0 V, but full enhancement requires ≤−10 V to achieve 0.28 Ω RDS(on). A level-shifting gate driver (e.g., Si823Hx) or charge pump is required for logic-level control in high-side configurations. Yes - it meets HBM ESD rating of ±2 kV per JESD22-A114, verified by factory testing. However, handling still requires grounded wrist straps and anti-static packaging, as gate oxide remains vulnerable to transient overvoltage beyond spec limits. Yes - the metal tab is internally connected to the drain and electrically isolated from source and gate pins. Thermal pad isolation voltage is rated at 2.5 kV RMS per UL 60950, allowing direct mounting to grounded heatsinks without insulating hardware.Availability
