Product details
Overview
IRF9530NL from Infineon Technologies is a P-channel enhancement-mode power MOSFET in TO-262 (straight-leads, low-profile through-hole) package, rated for -100 V VDS, 0.20 Ω RDS(on) at VGS = -10 V, and -14 A continuous drain current at TC = 25°C. It features full avalanche rating (250 mJ single-pulse), 175°C max junction temperature, and fast switching (tr = 58 ns, tf = 46 ns), used in DC-DC synchronous rectification and high-side load switching.
For engineers reviewing the IRF9530NL datasheet, IRF9530NL pinout, IRF9530NL application, or IRF9530NL equivalent, key selection criteria include verified -100 V blocking capability, confirmed 0.20 Ω on-resistance under -10 V gate drive, thermal derating behavior (0.53 W/°C), body diode recovery performance (trr = 130–190 ns), and TO-262 mechanical compatibility with low-profile PCB layouts.
Technical Context
This MOSFET operates as a high-voltage, medium-current P-channel switch with integrated body diode optimized for unclamped inductive switching. Its gate threshold voltage (-2.0 to -4.0 V) enables direct logic-level drive from 5 V microcontrollers when paired with appropriate level-shifting or gate buffering.
The device uses HEXFET® process technology to achieve low RDS(on) per die area while maintaining rugged avalanche performance. Thermal design relies on case-to-heatsink conduction (RθJC = 1.9 °C/W), not ambient convection (RθJA = 40 °C/W on 1"² FR-4), making it suitable for heatsink-mounted industrial power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -100 V - supports 80 V nominal bus systems with 20% margin for transients |
| RDS(on) | 0.20 Ω @ VGS = -10 V - delivers ≤1.4 W conduction loss at -8.4 A DC load |
| ID (cont) | -14 A @ TC = 25°C - requires heatsink for sustained >5 A operation above 70°C ambient |
| EAS | 250 mJ - withstands single inductive energy spikes without failure in motor drive snubbers |
| tr/tf | 58 ns / 46 ns - enables >100 kHz PWM switching with minimal overlap loss in half-bridge topologies |
| VSD | -1.6 V @ IS = -8.4 A - body diode forward drop impacts synchronous rectifier efficiency below 100 kHz |
| Qg | 58 nC - determines gate driver current requirement (~11.6 mA avg for 500 ns turn-on) |
Pinout & Package
IRF9530NL uses the TO-262 (I²PAK) package: straight-leaded, low-profile through-hole variant of the D2Pak, with 3.8 mm height and 10.6 mm × 10.2 mm footprint. Mounting torque: 10 lbf·in (1.1 N·m); soldering temp: 300°C for 10 s at 1.6 mm from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Accepts -10 V to -20 V drive; 58 nC total charge requires robust gate driver |
| D (Drain) | High-side power terminal | Connected to negative rail or load return; carries full load current and avalanche energy |
| S (Source) | Reference terminal | Biased at system ground or positive rail; body diode anode for reverse conduction path |
Key Features
| Feature | Design Value |
|---|---|
| P-channel enhancement mode | Enables high-side switching without level-shifting circuitry in negative-rail systems |
| 175°C maximum junction temperature | Supports operation in sealed enclosures or high-ambient industrial environments |
| Fully avalanche rated | Guarantees survivability during unclamped inductive turn-off events up to 250 mJ |
| Low-profile TO-262 package | Reduces board height vs. TO-220 while retaining through-hole mechanical reliability |
| Lead-free (PbF) construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles |
Applications
| Motor Drive Half-Bridge | Industrial Power Supply OR-ing |
|---|---|
Use Scenario: Bidirectional DC motor control using complementary P/N-channel half-bridge with freewheeling via body diode. IC Role / Device Role / Timing Role: High-side P-channel switch controlling motor voltage polarity; body diode handles reverse current during PWM off-time.

IC Role / Device Role / Timing Role: Reverse-polarity protection and automatic source selection via P-channel MOSFET acting as ideal diode. Use Value: -1.6 V VSD body diode drop replaced by 0.20 Ω channel resistance, cutting forward loss by >70% vs. Schottky solution at 5 A. |
| Telecom DC-DC Converter | Automotive Body Control Module |
Use Scenario: Isolated flyback secondary-side synchronous rectifier in 48 V telecom power system. IC Role / Device Role / Timing Role: Synchronous rectifier replacing Schottky diode; gated by transformer-coupled signal referenced to output rail. Use Value: 58 ns rise time ensures precise timing alignment with primary-side switch; -100 V rating accommodates reflected voltage spikes up to 85 V. | Use Scenario: High-side load switch for 12 V battery-fed lighting or solenoid circuits in vehicle door modules. IC Role / Device Role / Timing Role: Controlled power delivery with soft-start and overcurrent detection via external sense resistor. Use Value: TO-262 low profile fits tight Z-axis space behind door panel; -14 A rating supports 100 W incandescent loads with margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF9540NLPbF | VDS = -100 V, RDS(on) = 0.20 Ω (same), but ID = -17 A @ TC = 25°C and EAS = 320 mJ | Higher current handling and avalanche margin; same TO-262 footprint and pinout | Select when >14 A peak load or >250 mJ transient energy is expected |
| STP9PF10 | VDS = -100 V, RDS(on) = 0.22 Ω @ VGS = -10 V, ID = -9 A, TO-220 package | Lower current rating and different package; requires PCB redesign for mounting and thermal interface | Use only if TO-220 is mandated and 9 A continuous rating suffices |
Compared with IRF9530NL, IRF9540NLPbF offers higher current and avalanche capability in identical packaging, while STP9PF10 trades performance for legacy TO-220 compatibility-neither is a drop-in replacement without layout or thermal review.

FAQ
Is IRF9530NL suitable for logic-level gate drive?
No. Its gate threshold voltage range is -2.0 V to -4.0 V, but full enhancement requires -10 V VGS to achieve rated 0.20 Ω RDS(on). Driving with 3.3 V or 5 V logic alone results in high on-resistance (>1 Ω) and excessive heating. A dedicated gate driver or level shifter is required for reliable operation.
What is the maximum safe operating frequency for IRF9530NL?
Switching frequency is limited by thermal dissipation and gate drive capability-not intrinsic speed. With proper heatsinking and 1 A peak gate drive, it supports >200 kHz PWM in hard-switched topologies. However, above 100 kHz, body diode reverse recovery (trr = 130–190 ns) increases switching loss significantly in synchronous rectifier applications.
Can IRF9530NL replace IRF9530 in existing designs?
Yes, with qualification. IRF9530NL is the lead-free, low-profile TO-262 version of the legacy TO-220 IRF9530. Pinout and electrical specs are identical, but thermal resistance differs: RθJC is 1.9 °C/W (TO-262) vs. 2.5 °C/W (TO-220), improving heatsink coupling. Mechanical mounting and PCB footprint must be updated.
Does IRF9530NL require a gate resistor?
Yes. A series gate resistor (typically 10–47 Ω) is required to damp ringing caused by gate-drain capacitance (Crss = 170 pF) and parasitic inductance. Omitting it risks oscillation during switching transitions, leading to erratic behavior, increased EMI, and potential device failure due to localized hot spots.
