Product details
Overview
IRFD9020PBF from Vishay Siliconix is a P-channel enhancement-mode power MOSFET in HVMDIP (4-pin DIP) package, rated for -60 V VDS, 0.28 Ω RDS(on) at VGS = -10 V, and 1.6 A continuous drain current at 25 °C. It serves as a high-reliability, low-cost switching device in DC-DC converters, motor control circuits, and load-switching applications requiring ruggedized avalanche capability and 175 °C operation.
For engineers reviewing the IRFD9020PBF datasheet, IRFD9020PBF pinout, IRFD9020PBF application, or IRFD9020PBF equivalent, key selection criteria include its -60 V breakdown rating, repetitive avalanche energy (0.13 mJ), fast switching (13 ns turn-on delay), body diode recovery time (100–200 ns), and thermal resistance (120 °C/W junction-to-ambient).
Technical Context
This P-channel MOSFET uses third-generation silicon technology optimized for cost-sensitive, medium-power switching. Its dual-drain configuration provides enhanced thermal conduction to the PCB, enabling up to 1 W power dissipation without heatsinking. The device features dynamic dV/dt immunity (-4.5 V/ns) and is rated for repetitive avalanche under controlled inductive conditions (IAR = -1.6 A).
The HVMDIP package supports automated insertion and vertical stacking on 0.1" pitch headers. Internal source and drain inductances (LS = 6.0 nH, LD = 4.0 nH) are specified to support accurate switching waveform modeling in gate-drive design and EMI analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -60 V - Maximum blocking voltage before avalanche onset; defines usable input voltage range in high-side switch configurations. |
| RDS(on) | 0.28 Ω @ VGS = -10 V - Determines conduction loss (I²R) in linear and switching modes; enables <1.3 W total dissipation at 1.6 A. |
| Qg | 19 nC - Total gate charge required for full enhancement; sets minimum driver current and switching speed limits in PWM circuits. |
| ID (continuous) | -1.6 A @ TA = 25 °C - Safe steady-state current with natural convection; derates to -1.1 A at 100 °C ambient. |
| EAS | 140 mJ (single-pulse) - Energy-handling capacity during unclamped inductive switching; critical for relay/snubberless solenoid drive. |
| TJ range | -55 to +175 °C - Enables operation in automotive under-hood, industrial motor drives, and sealed power supplies without derating. |
| dV/dt rating | -4.5 V/ns - Immunity to false turn-on from rapid voltage transients; reduces need for external gate clamping in noisy environments. |
Pinout & Package
The IRFD9020PBF uses the HVMDIP (High Voltage Mini-DIP) 4-pin through-hole package. Dual drain leads (D1, D2) provide parallel current paths and serve as thermal anchors to the PCB ground plane. Package dimensions: 8.38 mm × 10.79 mm × 7.36 mm (L × W × H), 0.1" pin pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Pin 1 & Pin 4) | Drain (dual) | Parallel-connected drain terminals; both must be soldered to same net for rated current and thermal performance. |
| G (Pin 2) | Gate | Control terminal; requires -10 V for full enhancement; ±20 V absolute max gate-source voltage. |
| S (Pin 3) | Source | Reference node for gate drive; connects to load return or system ground in high-side switch topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Supports reliable operation under repeated inductive switching stress (IAR = -1.6 A, EAR = 0.13 mJ), eliminating need for external snubbers in many relay/motor drive designs. |
| Dynamic dV/dt immunity | -4.5 V/ns threshold prevents spurious turn-on during fast bus transients-critical in shared-rail industrial controls and battery disconnect systems. |
| 175 °C operating temperature | Enables deployment in thermally constrained enclosures (e.g., sealed LED drivers, automotive junction boxes) without forced air or heatsinks. |
| End stackable HVMDIP | Allows vertical board stacking of multiple units on standard 0.1" headers-reducing footprint in multi-channel power distribution modules. |
| Low-cost machine-insertable package | HVMDIP eliminates SMT reflow complexity while maintaining thermal performance comparable to SO-8 equivalents in ≤1 W applications. |
Applications
| DC-DC Buck Converter High-Side Switch | Industrial Relay Driver |
|---|---|
Use Scenario: 24 V input buck regulator supplying 15 V/1 A to PLC I/O modules in factory automation cabinets. IC Role / Device Role / Timing Role: High-side synchronous rectifier switch controlling power delivery during PWM on-time; body diode conducts during off-time.

Use Scenario: On/off control of 48 V LED strings in streetlight fixtures with thermal management constraints. IC Role / Device Role / Timing Role: Low-duty-cycle power switch activated by microcontroller GPIO; body diode reverse recovery (100–200 ns) limits switching loss during PWM dimming. Use Value: Fast trr and low Qrr (0.32–0.64 μC) reduce heat generation during 1–10 kHz dimming; HVMDIP simplifies manual repair in field-deployed units. |
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 |
|---|---|---|---|
| IRFD9024PBF | VDS = -60 V, RDS(on) = 0.18 Ω @ -10 V, Qg = 24 nC, same HVMDIP package | Lower on-resistance but higher gate charge; better for lower-loss static switching, worse for high-frequency PWM | Select when conduction loss dominates over switching loss and thermal margin is tight. |
| STP12PF06 | VDS = -60 V, RDS(on) = 0.22 Ω @ -10 V, TO-220 package, no avalanche rating | Larger footprint, no repetitive avalanche spec; requires external flyback protection in inductive loads | Choose only if PCB space allows TO-220 and application avoids unclamped inductive switching. |
Compared with IRFD9020PBF, IRFD9024PBF offers lower conduction loss but demands stronger gate drive; STP12PF06 trades ruggedness for thermal mass and lacks avalanche qualification-making IRFD9020PBF the optimal balance of robustness, size, and cost for mid-power industrial switching.

FAQ
What is the maximum continuous drain current for IRFD9020PBF at 100 °C ambient temperature?
The IRFD9020PBF supports -1.1 A continuous drain current at TA = 100 °C, per its Absolute Maximum Ratings table. This derating reflects thermal limitations of the HVMDIP package's 120 °C/W junction-to-ambient resistance. At higher ambient temperatures, further reduction is required to maintain TJ ≤ 175 °C. The IRFD9020PBF datasheet specifies linear derating beyond 25 °C using 0.0083 W/°C.
Does IRFD9020PBF require a gate resistor for safe operation?
Yes-IRFD9020PBF benefits from an external gate resistor (typically 10–100 Ω) to control dI/dt and suppress ringing caused by its internal LS (6.0 nH) and LD (4.0 nH). The datasheet's switching time test circuit (Fig. 10b) uses Rg = 18 Ω. Omitting it risks overshoot, shoot-through in half-bridge configurations, and accelerated gate oxide wear in IRFD9020PBF.
Can IRFD9020PBF replace an N-channel MOSFET in a high-side switch without level shifting?
No-IRFD9020PBF is a P-channel device and can operate as a high-side switch with gate driven relative to source (e.g., 0 V gate = ON, -10 V gate = fully enhanced), eliminating the need for bootstrap or isolated gate drivers required by N-channel high-side switches. However, its RDS(on) is higher than comparable N-channel parts, so IRFD9020PBF is selected for simplicity-not efficiency-in such roles.
Is IRFD9020PBF qualified for automotive applications?
The IRFD9020PBF is not AEC-Q101 qualified, though its -55 to +175 °C operating range and avalanche rating align with many automotive under-hood thermal requirements. For production automotive use, Vishay recommends AEC-Q101-qualified variants like the SQ-series; IRFD9020PBF remains suitable for non-safety-critical aftermarket or industrial transport systems where formal qualification is not mandated.
What is the body diode forward voltage of IRFD9020PBF at rated current?
The IRFD9020PBF body diode exhibits VSD = -6.3 V at IS = -1.6 A and TJ = 25 °C with VGS = 0 V. This relatively high forward drop reflects its optimized switching-rather than diode-performance. In applications relying on body diode conduction (e.g., synchronous rectification), this value directly impacts power loss and thermal design for IRFD9020PBF.
