Product details
Overview
IRF9952PBF from Infineon Technologies is a dual-channel complementary MOSFET pair featuring one N-channel and one P-channel enhancement-mode device in a single SO-8 package. It delivers RDS(on) of 0.042 Ω (N-ch, VGS = 10 V, ID = 3.5 A) and 0.075 Ω (P-ch, VGS = −10 V, ID = −2.3 A), with ±20 V gate-source voltage rating and −60 V/60 V drain-source breakdown voltage. It is used in half-bridge motor control stages for 12 V DC brushed motors.
For engineers reviewing the IRF9952PBF datasheet, IRF9952PBF pinout, IRF9952PBF application, or IRF9952PBF equivalent, this part supports synchronous rectification, bidirectional load switching, and compact H-bridge driver designs where matched N/P channel characteristics and thermal coupling are critical.
Technical Context
The IRF9952PBF integrates thermally coupled N- and P-channel MOSFETs sharing a common source configuration per channel (D1/G1/S1 and D2/G2/S2), enabling complementary drive without external level-shifting. Its gate threshold voltages are VGS(th) = 1–2.5 V (N-ch) and −1–−2.5 V (P-ch), supporting 3.3 V and 5 V logic-level drive.
It exhibits normalized RDS(on) variation ≤2.0× over −60 °C to +150 °C junction temperature, and single-pulse avalanche energy ratings of 12 mJ (N-ch) and 10 mJ (P-ch) at TJ = 25 °C, confirming ruggedness in inductive switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS (N-ch) | 60 V - supports 48 V nominal bus systems with 20 % margin |
| VDS (P-ch) | −60 V - enables symmetric rail-to-rail switching in dual-supply topologies |
| RDS(on) (N-ch) | 0.042 Ω @ VGS = 10 V, ID = 3.5 A - limits conduction loss to ≤0.52 W at 3.5 A |
| RDS(on) (P-ch) | 0.075 Ω @ VGS = −10 V, ID = −2.3 A - yields ≤0.40 W conduction loss at rated current |
| Qg (N-ch) | 12 nC @ VGS = 10 V - determines gate drive power and switching speed in PWM at ≤100 kHz |
| Qg (P-ch) | 10 nC @ VGS = −10 V - ensures matched turn-on timing with N-channel for reduced shoot-through risk |
| TJ max | 150 °C - allows operation in sealed enclosures with 40 K ambient rise under full load |
Pinout & Package
IRF9952PBF is housed in a standard SO-8 surface-mount package (5.0 mm × 6.0 mm, 1.27 mm pitch), with exposed drain pads for both channels thermally connected to the PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | N-channel gate | Logic-level input; requires ≥3.5 V to fully enhance N-MOSFET |
| 2 (S1) | N-channel source | Common source node for N-ch; tied to low-side reference or current sense point |
| 3 (D1) | N-channel drain | High-side switch output; connects to load supply rail |
| 4 (D2) | P-channel drain | Low-side switch output; connects to load return path |
| 5 (S2) | P-channel source | Common source node for P-ch; tied to high-side reference or supply rail |
| 6 (G2) | P-channel gate | Inverted logic input; driven low to turn on P-MOSFET |
| 7, 8 (D1/D2 tab) | Drain thermal pads | Internally connected to pins 3 and 4; must be soldered to PCB copper for thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Complementary dual MOSFET | Matched VGS(th) and RDS(on) tracking across temperature improves H-bridge symmetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar complementary dual MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si7951DP-T1-GE3 | RDS(on) = 0.035 Ω (N), 0.055 Ω (P); lower Qg but 40 V VDS rating | Not suitable for 48 V bus or ISO 7637-2 transient immunity | Select when operating strictly ≤36 V and prioritizing switching efficiency over ruggedness |
| DMC2038LSD-13 | RDS(on) = 0.052 Ω (N), 0.085 Ω (P); higher thermal resistance (RθJA = 62 °C/W) | Limited to <2 A continuous due to thermal derating in enclosed environments | Choose only for cost-sensitive, low-duty-cycle applications with ample heatsinking |
Compared with Si7951DP and DMC2038LSD, IRF9952PBF offers superior avalanche energy, wider VDS margin, and tighter parametric matching-making it preferred for industrial and automotive H-bridge designs requiring reliability under transient stress.

FAQ
What is the maximum continuous drain current for each channel at 100 °C case temperature?
At TC = 100 °C, the N-channel supports ID = 2.2 A (derated from 3.5 A at 25 °C), and the P-channel supports ID = −1.6 A (derated from −2.3 A). These values are based on SO-8 thermal resistance (RθJC = 3.5 °C/W) and maximum junction temperature of 150 °C.
Can IRF9952PBF be used in synchronous buck converter topologies?
No-IRF9952PBF is not optimized for synchronous buck operation. Its P-channel device has higher RDS(on) and slower switching than dedicated high-side drivers, and its gate drive asymmetry increases shoot-through risk. It is intended for half-bridge and bidirectional switching, not DC-DC regulation.
Is the SO-8 package lead-free and RoHS compliant?
Yes, IRF9952PBF is manufactured with 100 % matte tin plating and complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life at ≤30 °C/60 % RH.
How is the thermal pad on pins 7 and 8 electrically isolated?
Pins 7 and 8 are internally connected solely to their respective drain terminals (D1 and D2) and are not electrically tied together. The exposed copper pad beneath the SO-8 body is split into two isolated regions, each bonded to D1 and D2 respectively-enabling independent thermal sinking without shorting the high- and low-side drains.
