Overview
The BAV199FMFHT106 is a low-leakage switching diode designed for automotive applications, manufactured by ROHM Semiconductor. It features a series connection configuration within an SOT-323 (UMD3) surface-mount 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 capacity of 4000mA. It exhibits a low reverse current of 0.01µA at 75V and a forward voltage of 1.25V at 150mA. The junction temperature rating reaches 150°C, ensuring reliability in demanding environments.
Feature Summary
- Low leakage characteristics suitable for general switching purposes
- Automotive-grade reliability compliant with AEC-Q101 standards
- Compact SC-70 surface-mount package design
Applications
- General purpose switching circuits
- Automotive electronic systems requiring high reliability
- Low leakage signal processing applications
Procurement Notes
Verify the complete part number including the suffix T106 to confirm the taping packaging format and unit quantity. Ensure compatibility with the specified SOT-323 footprint during PCB layout. Confirm RoHS compliance status if required by specific environmental regulations. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions or thermal management guidelines.
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 automotive supply rails. The SOT-323 package offers space efficiency for dense board layouts. Consider the 150°C junction temperature limit for high-temperature operational environments. Verify that the 0.215A average current meets the load requirements of the specific application.
Part Context
This component belongs to ROHM's automotive-grade switching diode portfolio, specifically engineered for robustness in vehicle electronics. The BAV199 series is characterized by its low leakage properties, distinguishing it from standard general-purpose diodes. The FMFH suffix indicates the specific tape-and-reel packaging variant. This product line addresses the stringent reliability and quality standards mandated by the automotive industry.
Replacement Considerations
The DAN217U is listed as a similar level replacement with the same pinout and package, though it has a lower reverse voltage rating of 80V compared to the BAV199's 100V peak rating. The BAV99FM is another alternative but differs in reverse voltage specifications. Verify electrical parameter compatibility before substitution.
