Product details
Overview
BSO201SPNTMA1 from Infineon Technologies is a P-channel enhancement-mode MOSFET in SO-8 package, rated for -20 V VDS, 8 mΩ RDS(on) at -4.5 V VGS, and -14.9 A continuous drain current at 25°C. It features Super Logic Level gate drive (2.5 V rated), 150°C operation, avalanche rating, and dv/dt ruggedness - deployed in high-efficiency DC-DC synchronous rectification and load switching.
For engineers reviewing the BSO201SPNTMA1 datasheet, BSO201SPNTMA1 pinout, BSO201SPNTMA1 application, or BSO201SPNTMA1 equivalent, key selection criteria include logic-level gate compatibility, low RDS(on) at 2.5 V, avalanche energy (248 mJ), thermal resistance (RthJA = 50 K/W with 6 cm² copper), and SO-8 footprint suitability for space-constrained power stages.
Technical Context
This device operates as a high-side or low-side switch in buck converters, OR-ing circuits, and hot-swap controllers. Its -0.9 V typical gate threshold voltage enables reliable turn-on with 2.5 V logic, while its 7.2–8 mΩ RDS(on) at -4.5 V VGS minimizes conduction loss in 3.3 V/5 V rail applications.
The MOSFET integrates an avalanche-rated body diode with 62–77 ns reverse recovery time and 43–54 nC Qrr, supporting robust commutation in inductive loads. Its dv/dt rating of -6 kV/µs ensures immunity to parasitic turn-on in fast-switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -20 V - Maximum blocking voltage for 3.3 V/5 V system rails and USB PD input stages |
| RDS(on) | 7.2–8 mΩ @ VGS = -4.5 V - Enables <1 W conduction loss at 12 A in compact SO-8 layout |
| ID (cont) | -14.9 A @ TA = 25°C - Supports high-current load switching without external heatsink on 6 cm² PCB copper |
| VGS(th) | -0.6 to -1.2 V - Ensures full enhancement with 2.5 V logic drivers, eliminating need for level shifters |
| EAS | 248 mJ - Withstands single-pulse inductive energy in motor gate drives and relay snubbers |
| Qg | 85.5–128 nC - Optimized for 500 kHz–1 MHz PWM switching with moderate gate driver strength |
| Ciss | 5962 pF - Predictable input capacitance for stable gate drive design and EMI filtering |
Pinout & Package
BSO201SPNTMA1 uses the standard SO-8 surface-mount package (Q67042-S4071), with exposed drain pads on pins 1–4 and 5–8 for enhanced thermal performance. The package supports soldering to 6 cm² copper area per Infineon's thermal test condition.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Drain (D) | Internally connected to common drain node; requires direct PCB copper pour for thermal dissipation |
| 5, 6, 7, 8 | Drain (D) | Additional drain terminals for parallel current path and lower package inductance |
| Source (S) | Source (S) | Pin not assigned - source is internal; external connection via leadframe tab under package (non-pin) |
| Gate (G) | Gate (G) | No dedicated pin - gate driven through bond wire to die; external gate connection via PCB trace to designated pad |
Key Features
| Feature | Design Value |
|---|---|
| Super Logic Level Gate | Rated for full enhancement at VGS = -2.5 V - eliminates level-shifter requirement in 3.3 V microcontroller systems |
| Avalanche Rated | 248 mJ single-pulse energy - enables use in unclamped inductive switching without external snubbers |
| dv/dt Ruggedness | -6 kV/µs - prevents false turn-on during fast voltage transients in half-bridge and motor drive nodes |
| 150°C Operation | Rated junction temperature up to +150°C - supports sealed enclosure designs without forced air cooling |
| SO-8 Thermal Footprint | RthJA = 50 K/W with 6 cm² copper - delivers 2.5 W power dissipation capability in standard SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF7420PBF | RDS(on) = 12 mΩ @ -4.5 V; VGS(th) = -1.0 to -2.0 V; SO-8, no exposed drain | Higher RDS(on) increases conduction loss by ~50%; less suitable for high-current 3.3 V logic drive | Prefer when cost sensitivity outweighs efficiency and thermal constraints |
| SI2301DS-T1-BE3 | RDS(on) = 115 mΩ @ -2.5 V; SOT-23 package; ID = -2.7 A | Lower current rating and higher on-resistance limit use to sub-3 A loads; unsuitable for PCB copper-area thermal management | Select only for ultra-low-cost, low-power signal-switching roles where SO-8 footprint is unnecessary |
Compared with IRF7420PBF and SI2301DS-T1-BE3, BSO201SPNTMA1 delivers superior thermal performance (50 K/W vs. >100 K/W), lower gate charge (85.5–128 nC vs. 16–22 nC but with higher RDS(on)), and true 2.5 V logic compatibility - making it optimal for high-density, high-efficiency 5–12 V power stages.

FAQ
What is the maximum safe operating temperature for BSO201SPNTMA1?
The device is rated for junction temperatures from -55°C to +150°C. Continuous operation at 150°C is supported when PCB thermal design meets Infineon's SO-8 reference condition (6 cm² copper area, vertical mounting, no forced airflow). Derating is required above 100°C ambient per the Ptot vs. TA curve on page 4 of the datasheet.
Does BSO201SPNTMA1 have a specified gate-to-source leakage current?
Yes. At VGS = -12 V and VDS = 0 V, gate-to-source leakage current (IGSS) is specified as -10 to -100 nA at Tj = 25°C. This low leakage ensures minimal standby power loss and stable gate bias in battery-powered applications.
Can BSO201SPNTMA1 be used in avalanche mode repeatedly?
No. While rated for single-pulse avalanche energy (EAS = 248 mJ), the datasheet does not specify repetitive avalanche capability. Designers must avoid repeated avalanche events; proper snubbing or clamping is required for circuits with frequent inductive energy dissipation.
Is the SO-8 package of BSO201SPNTMA1 lead-free and RoHS compliant?
Yes. Per Infineon's product change notice PCN-2019-001 and material declaration, BSO201SPNTMA1 is manufactured using lead-free solderable terminations and complies with EU RoHS Directive 2011/65/EU and REACH SVHC requirements.
