IRF9952TRPBF - Dual N+P 30V MOSFET Array, SO-8 | Infineon
MPN: IRF9952TRPBF ✓ Hoạt độngIRF9952TRPBF Tóm tắt
A dual-MOSFET array like the IRF9952 integrates two discrete transistors into one IC package, providing a compact synchronous-switch or half-bridge building block for power management designs. In the system hierarchy, this part falls under discrete semiconductors (MOSFETs) and specifically into the dual/complementary MOSFET category that bridges single-MOSFET discretes and full half-bridge driver ICs. The complementary N+P configuration lets one array drive both high-side and low-side positions of a small buck, load-switch, or motor-reverse circuit without the BOM overhead of two separate SOT-23 or SO-8 FETs.
Key features include: 30 V absolute maximum VDS (N-channel) and -30 V VDS (P-channel), 3.5 A continuous I_D (N-channel) and 2.3 A continuous I_D (P-channel), 2 W total package power dissipation, and SO-8 surface-mount footprint. The complementary polarity means the P-channel is well suited to high-side load-switch roles where a P-FET eliminates the need for a charge pump, while the N-channel can serve as the low-side synchronous rectifier. Per the Infineon datasheet, total power dissipation is shared across both die inside the same SO-8 thermal envelope, with thermal resistance around 62.5 C/W.
Architecturally, the IRF9952 leverages Fifth Generation HEXFET technology, which optimized cell density and gate-charge figures to minimize both conduction and switching losses versus earlier generations. The two die share pin 4 and pin 5 as the common source/drain return path, while pins 1-3 are dedicated to the N-channel (G1, D1, S1) and pins 6-8 to the P-channel (G2, D2, S2). This pinout makes it a drop-in upgrade for legacy IRF7507/IRF7509 family designs.
Typical applications include small DC-DC synchronous buck converters, USB load switches, battery protection circuits in portable electronics, small motor H-bridge driver stages, and complementary level shifters in industrial control. The 30 V rating and 3.5 A capability also make it suitable for 12 V automotive accessory rails.
When designing with this part, derate total package power dissipation so both die stay within the 2 W SO-8 budget. Gate-drive voltage thresholds differ between the N-channel (logic-level friendly) and the P-channel (which needs careful gate-source headroom). Pair the array with a gate driver that can source/sink enough current for the combined gate charge (typical Qg figures are 10-20 nC per channel).

Ứng dụng tiêu biểu
IRF9952TRPBF phù hợp cho 6 Áp dụngs: USB Load Switch and Power Distribution, Small DC-DC Synchronous Buck Converter, Battery Protection and Portable Electronics, Motor Driver H-Bridge Half-Bridge, Automotive 12V Accessory Rail Switching, Complementary Level Shifter and Signal Switch.
USB Load Switch and Power Distribution
The IRF9952TRPBF is ideal for USB Type-A load-switch and small power-distribution switch roles on 5 V rails. The integrated P-channel (30 V, 2.3 A) handles the high-side switch without a charge pump, while the N-channel (30 V, 3.5 A) can serve as a return-side synchronous element or be paralleled for redundancy. With 0.10 ohm N-channel R_DS(on) at 10 V VGS, conduction loss at 0.5 A is only 25 mW, well below the 2 W SO-8 envelope. The complementary N+P pair eliminates the need for two discrete SOT-23 FETs, saving PCB area in hubs and charging ports.

Small DC-DC Synchronous Buck Converter
The IRF9952TRPBF suits low-current synchronous buck designs from 24 V down to 5 V/3.3 V rails. The P-channel operates as the high-side switch, while the N-channel acts as the low-side synchronous rectifier, and both share the same SO-8 footprint and 2 W dissipation budget. With N-channel R_DS(on) of 0.10 ohm and Qg figures in the 10-20 nC range, switching losses at 500 kHz are manageable. Pair with a small gate driver or PWM controller such as the TPS54331 family for sub-1 A point-of-load designs.

Battery Protection and Portable Electronics
The IRF9952TRPBF is widely used in single-cell Li-ion battery protection and small portable power paths. The P-channel handles the high-side disconnect role, blocking reverse current when the battery is depleted, while the N-channel can carry return current or act as a secondary protection FET. With 30 V VDS and 2.3 A P-channel rating, the part comfortably handles 4.2 V Li-ion up to USB-monitored 2 A charge currents. The SO-8 package is footprint-compatible with most 1-cell protection PCBs.

Motor Driver H-Bridge Half-Bridge
The IRF9952TRPBF can build a small brushed DC motor H-bridge when paired with a complementary second array. The N-channel handles low-side switching and the P-channel handles high-side switching on each half-bridge leg, eliminating the need for charge-pump high-side gate drive. With 3.5 A N-channel and 2.3 A P-channel capability, the bridge drives small motors up to roughly 1 A continuous, suitable for fans, pumps, toys, and consumer robotics. The complementary pair reduces gate-driver complexity versus all-N designs.

Automotive 12V Accessory Rail Switching
The IRF9952TRPBF operates on 12 V automotive rails with substantial margin (30 V VDS vs 12 V nominal, 35 V load-dump safe). It switches interior lighting, accessory sockets, and small actuator loads from 12 V battery. The P-channel high-side switch has no quiescent current path when off, which suits always-on battery applications. Although the part is Consumer-qualified rather than AEC-Q100, the SO-8 dual N+P architecture is widely used in non-safety automotive subsystems.
Được đề xuất
Complementary Level Shifter and Signal Switch
The IRF9952TRPBF can implement a small complementary analog switch or level shifter for signals between 0 V and 30 V. The P-channel passes high-side signals, the N-channel passes low-side signals, and the SO-8 dual fits into tiny analog-front-end circuits. Typical use cases include USB-C CC/SBU signal muxing, audio line switching, and small-signal routing in test equipment. The 0.10/0.25 ohm on-resistance is acceptable for sub-100 mA analog signals.

Ghi chú thiết kế
Estimated: The IRF9952TRPBF SO-8 thermal resistance is approximately 62.5 C/W (junction to ambient on JEDEC EIA/JESD51 test board). With combined 2 W dissipation, junction temperature rises 125C above ambient, so continuous load must be derated. Practical continuous current per channel in still air on a 1 sq inch copper pour is roughly 1.5 A N-channel and 1.0 A P-channel before reaching 100C junction. Add thermal vias or copper pours if the design runs near full rated current.
Place the IRF9952TRPBF on a contiguous ground/return copper pour tied to pins 1, 5, and 8 (the three source pins). Keep the high-current drain traces (pins 4, 3, 6) wide and short to minimize parasitic inductance that can spike VDS above the 30 V rating. A small gate-series resistor (10-47 ohm) damps ringing on the N-channel gate. Mirror the layout for pins 4 and 5 versus pins 3 and 6 to balance the two die thermally.
Do not drive the P-channel gate above ground or below its absolute maximum VGS of +/-20 V. Per the Infineon datasheet, gate-oxide breakdown typically occurs at 20 V on either channel, so a 12 V gate-drive level is the practical maximum. Also note that R_DS(on) is specified at VGS = 10 V; logic-level drive at 5 V will roughly double or triple R_DS(on). Finally, do not parallel the two channels in the same package - they share die and will not current-share.
Estimated: Conduction loss in the N-channel at 1 A continuous and 0.10 ohm R_DS(on) is 100 mW; the P-channel at 1 A and 0.25 ohm is 250 mW. Total steady-state loss of 350 mW is well within the 2 W envelope. Switching losses depend on Qg (typically 10-20 nC per channel) and switching frequency; at 500 kHz with 10 nC Qg, switching loss is roughly 50 mW per channel. Total power budget supports operation up to about 5 A peak in pulse mode.
