Overview
The BSS84 is a P-channel enhancement mode MOSFET housed in an SOT-23 package. It features a drain-source voltage of -60V and a continuous drain current of -0.23A. The device includes built-in ESD protection diodes. Typical on-resistance is 3.5Ω at VGS=-4.5V and 2.8Ω at VGS=-10V. Maximum power dissipation is 0.35W, with an operating temperature range from -55°C to +150°C.
Feature Summary
- Utilizes trench MOSFET technology for high-speed switching capabilities.
- Integrates internal ESD protection diodes within the single-channel structure.
- Designed for low-voltage drive applications with typical operation at -4.5V.
Applications
- High-side load switching circuits
- Relay driver applications
- General-purpose switching circuits
Procurement Notes
Verify the specific manufacturer, as Analog Power Inc. is not a recognized primary source for this component. Confirm if the part corresponds to ROHM (BSS84T116) or UMW specifications. Ensure the datasheet matches the required -60V rating and SOT-23 package dimensions before procurement.
Selection Notes
Select this component for low-power switching tasks requiring a compact SOT-23 footprint. It is suitable for driving relays or managing high-side loads where moderate current handling up to 230mA is sufficient. Consider thermal constraints due to the 350mW power dissipation limit in small packages.
Part Context
This component belongs to the family of small-signal P-channel MOSFETs commonly used in portable electronics and automotive systems. The SOT-23 form factor allows for space-efficient PCB layouts. Similar parts often include integrated protection features to enhance reliability in sensitive signal paths.
Replacement Considerations
ROHM BSS84T116: Verified equivalent with identical -60V/-0.23A ratings and SOT-23 packaging. UMSS BSS84: Verify if -50V variant meets system requirements. Diodes Inc. BSS84DW-7-F: Dual channel version; pinout compatibility must be confirmed.
