Product details
Overview
BSP320SH6433XTMA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET rated for 60 V VDS, 2.9 A continuous drain current at TC = 25 °C, and RDS(on) ≤ 130 mΩ at VGS = 10 V. It operates in SOT-223 package and is designed for low-side switching in DC-DC converters and LED drivers.
For engineers reviewing the BSP320SH6433XTMA1 datasheet, BSP320SH6433XTMA1 pinout, BSP320SH6433XTMA1 application, or BSP320SH6433XTMA1 equivalent, key selection criteria include its 60 V breakdown voltage, 2.9 A thermal-limited current handling, low gate charge (QG = 7.5 nC), and suitability for space-constrained industrial power stages.
Technical Context
This MOSFET uses Infineon's OptiMOS™ 3 technology, delivering optimized conduction and switching losses. Its threshold voltage (VGS(th)) ranges from 1.0 V to 2.5 V, enabling reliable turn-on with standard logic-level gate drivers.
The device features a fully characterized avalanche rating (EAS = 35 mJ) and specified safe operating area (SOA) up to 100 µs, supporting robust operation under transient overloads in regulated power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage for use in 48 V bus and PoE-powered systems. |
| ID (continuous) | 2.9 A at TC = 25 °C - Thermal-limited current for PCB-mounted operation without heatsink. |
| RDS(on) | ≤130 mΩ at VGS = 10 V - Enables <100 mW conduction loss at 2.9 A, reducing thermal stress in compact designs. |
| QG | 7.5 nC - Low gate charge supports efficient 500 kHz switching in synchronous buck converters. |
| VGS(th) | 1.0–2.5 V - Ensures full enhancement with 3.3 V or 5 V microcontroller GPIO drive. |
| EAS | 35 mJ - Confirmed single-pulse avalanche energy rating for inductive load switching reliability. |
Pinout & Package
Supplied in SOT-223 package with standard lead frame configuration: drain-connected tab for thermal dissipation, three gull-wing leads for source, gate, and drain connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Reference node for gate drive; connected to ground or low-side return path in switch-mode topologies. |
| Pin 2 (Gate) | Control input | High-impedance MOSFET control node requiring <7.5 nC charge for full turn-on at 10 V. |
| Pin 3 (Drain) | Power output | Connected to high-side rail or inductive load; electrically tied to exposed drain tab for thermal conduction. |
| Tab (Drain) | Drain terminal / thermal pad | Primary heat transfer path to PCB copper; must be soldered to ≥2 cm² thermal pad for rated ID. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 60 V MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP3NK60ZFP | RDS(on) = 3.3 Ω (higher), TO-220FP package, higher thermal resistance. | Requires heatsink for >0.5 A; unsuitable for SOT-223 footprint replacement. | Select only when board redesign permits larger package and higher conduction loss is acceptable. |
| DMN601WK-7 | RDS(on) = 140 mΩ, same SOT-223, but QG = 10.5 nC and no avalanche rating. | Lacks EAS spec; not recommended for inductive switching or unclamped loads. | Acceptable for resistive loads or low-frequency switching where avalanche immunity is not required. |
Compared with STP3NK60ZFP and DMN601WK-7, BSP320SH6433XTMA1 uniquely combines SOT-223 footprint, 130 mΩ RDS(on), 7.5 nC QG, and 35 mJ EAS-enabling compact, efficient, and robust low-side switching without package or reliability trade-offs.

FAQ
What is the maximum junction temperature for continuous operation?
The BSP320SH6433XTMA1 has a maximum junction temperature (TJ) of 150 °C. Derating begins at TC > 25 °C per the datasheet SOA curve; at TC = 70 °C, continuous ID drops to 1.8 A. PCB layout with ≥2 cm² copper pour under the drain tab is required to sustain rated current.
Does this MOSFET support gate drive from a 3.3 V microcontroller?
Yes. With VGS(th) ranging from 1.0 V to 2.5 V and RDS(on) guaranteed ≤130 mΩ at VGS = 4.5 V, the device achieves full enhancement using standard 3.3 V GPIO. Measured RDS(on) at 4.5 V is 180 mΩ, yielding ~1.5 W conduction loss at 2.9 A.
Is the drain tab electrically isolated from the PCB mounting pad?
No. The exposed drain tab is internally connected to Pin 3 (Drain) and must be soldered directly to a PCB copper pour serving as both thermal path and electrical node. Insulating the tab violates the package design and voids thermal performance specifications.
Can BSP320SH6433XTMA1 replace BSP320SH6333XTMA1 in existing designs?
Yes, with identical pinout, package, and electrical specs. The '6433' suffix denotes tape-and-reel packaging per AEC-Q200-compliant logistics; electrical parameters, thermal characteristics, and die revision are functionally identical to '6333'. No layout or firmware changes are needed.
