Overview
The FMW2T148 is a general-purpose NPN bipolar junction transistor manufactured by Rohm Semiconductor. It features a five-pin surface-mount configuration housed in the SOT-25T (SC-74A) package. The device supports a maximum reverse voltage of 80V and an average rectified forward current of 25mA, with a peak surge current capacity of 250mA. Key electrical characteristics include a forward voltage of 0.9V at 5mA and a reverse leakage current of 0.1µA at 70V. The component operates within a junction temperature range up to 150°C and is designed for standard electronic applications.
Feature Summary
- Five-terminal surface-mount architecture suitable for compact circuit designs
- High-voltage tolerance capability for signal processing tasks
- Integrated thermal stability for reliable operation under varying conditions
Applications
- General-purpose switching circuits
- Signal amplification stages
- Low-power logic interface applications
Procurement Notes
Verify the specific ordering suffix against official Rohm documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain component integrity during handling and assembly processes.
Selection Notes
Select this component when a small-footprint NPN transistor with 80V blocking capability is required. The SOT-25T package offers space efficiency compared to larger through-hole alternatives. Evaluate the 25mA continuous current rating against load requirements to ensure adequate margin for thermal management and long-term reliability in the target application environment.
Part Context
This part belongs to Rohm's series of small-signal switching diodes and transistors designed for high-reliability consumer electronics. The product line emphasizes compact packaging solutions that support automated surface-mount assembly processes. These components are engineered to meet stringent quality standards for mass-produced electronic devices requiring consistent performance.
Replacement Considerations
Consult official substitution guides for compatible equivalents. Verify pinout compatibility and electrical parameter overlaps before implementing any alternative components in existing designs.
