1. Current Capability and Forward Voltage Drop - B340BQ-13-F: 3A, 500mV @ 3A; VS-10BQ040: 1A, 450mV @ 1A. - The higher current margin of the B340BQ improves system reliability. However, forward voltage drop should be compared under the same test current (e.g., at 1A, the B340BQ may exhibit a lower actual Vf). 2. Reverse Leakage Current - B340BQ-13-F: 500µA @ 40V; VS-10BQ040: 100µA @ 40V. - The B340BQ shows higher leakage, typical for high-current Schottky diodes. Leakage may increase further at elevated temperatures; power dissipation and thermal management should be evaluated in low-power or high-temperature environments. 3. Junction Capacitance - B340BQ-13-F: 200pF @ 4V; VS-10BQ040: 115pF @ 5V. - The higher junction capacitance of the B340BQ can lead to increased switching losses and degraded high-frequency noise performance, making it unsuitable for high-frequency switching circuits (e.g., DC-DC converters operating above 1MHz). 4. Reliability Qualification - B340BQ-13-F is AEC-Q101 qualified, whereas the VS-10BQ040 lacks this certification. - The B340BQ meets automotive reliability requirements (e.g., temperature cycling, humidity endurance) and is suitable for harsh environments such as industrial and automotive applications. The VS series is limited to general commercial use. 5. Price and Cost Performance - The B340BQ-13-F is significantly lower in cost ($0.17 vs. $0.42). - While maintaining compatibility, the B340BQ offers higher current capability, automotive-grade reliability, and lower cost, delivering a clear cost-performance advantage.
