Single Diodes Procurement Notes

Verify that the ordering suffix matches the required tape and reel quantity of 3000 pieces per reel. Confirm the manufacturer is Micro Commercial Components and the marking code is A2. Ensure compliance with RoHS directives and check for authorized distributor status to guarantee genuine parts with full traceability. Validate the SOT-323 package dimensions against mechanical constraints.

Single Diodes Selection Notes

Select this component when a compact SOT-323 footprint is required for high-speed switching applications. The 100V non-repetitive peak reverse voltage provides adequate margin for standard 5V and 12V logic systems. Consider the 200mW power dissipation limit and thermal resistance of 625°C/W for proper heat management in dense PCB layouts.

Single Diodes Part Context

This part belongs to the BAS16WT and MMBD4148WT family from Micro Commercial Components. These devices are designed as general-purpose switching diodes offering fast recovery times. The series utilizes a small outline transistor-style package suitable for automated surface-mount assembly processes in consumer and industrial electronics.

Single Diodes Replacement Considerations

Direct substitutes within the same MCC family include the BAS16WT variant, which shares identical pinout and similar electrical ratings. Verify that any replacement maintains the SOT-323 package and meets the 4.0ns reverse recovery time requirement for equivalent circuit performance.
