BAV199UMTL

Overview

The BAV199UMTL is a low-leakage switching diode manufactured by ROHM Semiconductor. It features a series connection configuration within an SMD UMD3F (SOT-323FL) package. Key electrical specifications include a maximum reverse voltage of 80V and a peak repetitive reverse voltage of 100V. The device supports an average rectified forward current of 0.215A with a surge forward current capability of 4000mA. Forward voltage is specified at 1.25V when the current is 150mA, while reverse current is limited to 0.005µA at 75V. The typical reverse recovery time is 3000ns.

Feature Summary

• Low leakage characteristics suitable for general switching applications
• Series connection configuration for dual-diode functionality in a compact footprint
• High reliability design utilizing small mold type construction

Applications

• General purpose switching circuits
• Signal processing in consumer electronics
• Protection circuits requiring low leakage current

Procurement Notes

Verify the specific ordering suffix UMTL against the official ROHM datasheet to confirm the tape-and-reel packaging quantity and RoHS compliance status. Ensure the component matches the UMD3F package dimensions and pinout configuration required for the target PCB layout. Cross-reference the supply status as recommended or active to avoid obsolescence risks during production.

Selection Notes

Select this component when low reverse leakage current is critical for circuit performance. The 80V reverse voltage rating provides adequate margin for standard low-voltage logic and signal lines. The SOT-323FL package offers space efficiency for portable devices. Consider the 3000ns reverse recovery time for frequency limitations in high-speed switching environments compared to faster alternatives.

Part Context

This part belongs to the BAV199 series of switching diodes from ROHM Semiconductor. It is designed as a replacement for older standards like the BAV99 but with optimized leakage characteristics. The series is widely used in digital logic interfaces and signal routing where compact size and reliable switching are required without automotive grade certification.

Replacement Considerations

BAV199UMFHTL shares the same series specification and package type.
