Overview
The BSS84W-TP is a P-channel enhancement mode MOSFET manufactured by Micro Commercial Components (MCC). It is housed in the SOT-323 surface-mount package, also designated as UMT3 or SC-70. The device supports a drain-source voltage of -60V and a continuous drain current of -0.21A. Key electrical characteristics include an on-resistance of 3.5 ohms at Vgs = -4.5V and 2.8 ohms at Vgs = -10V. Power dissipation is rated at 0.3W, with an operating temperature range from -55°C to 150°C.

Procurement Notes
Verify the specific datasheet version and revision history before integration, as manufacturing parameters may evolve. Confirm that the SOT-323 thermal performance meets the system's power dissipation requirements under actual operating conditions. Ensure compatibility with the intended gate drive voltages specified in the official documentation.
Selection Notes
Select this component when a small form factor is required alongside moderate current handling capabilities. The integrated ESD protection adds robustness for sensitive signal lines. Verify that the -60V rating exceeds the maximum circuit voltage and that the on-resistance values align with the efficiency targets of the specific application design.
Part Context
This part belongs to the BSS84 series of P-channel MOSFETs produced by MCC. It shares functional similarities with other industry-standard devices but is distinguished by its specific packaging and internal ESD structures. The product line focuses on providing reliable switching solutions for consumer and industrial electronics requiring compact transistor footprints.
Replacement Considerations
Cross-reference with standard BSS84 variants from other manufacturers only if pinout and electrical ratings are identical. Verify that substitute components maintain the same SOT-323 mechanical dimensions and thermal characteristics to ensure board compatibility.
