Frequently Asked Questions (FAQ)

Q: Can BAV19WS-7-F be used as a direct replacement for BAV19WS-7?

A: Yes. The BAV19WS-7-F is the direct manufacturer substitute from Diodes Incorporated with identical electrical specifications. All key parameters—voltage rating, current rating, forward voltage, reverse recovery time, reverse leakage current, and junction temperature range—are identical. The part is active in production and ROHS3 compliant. No circuit modification is required.

Q: What is the difference between the onsemi substitutes (SBAS16HT3G and SMMDL914T1G) and the original BAV19WS-7?

A: Both onsemi parts meet the core electrical requirements (100 V reverse voltage, 200 mA current rating). However, they offer improved switching performance with significantly faster reverse recovery times (6 ns and 4 ns respectively, compared to 50 ns for the original). The SMMDL914T1G also features lower forward voltage drop (1 V @ 10 mA). Both parts have higher reverse leakage currents (1 µA and 5 µA respectively, compared to 100 nA for the original) and narrower junction temperature ranges (-55°C to 150°C, compared to -65°C to 150°C for the original). These differences are acceptable for general-purpose rectification applications.

Q: Are the Taiwan Semiconductor Corporation and Micro Commercial Co substitutes equivalent to the original BAV19WS-7?

A: Yes. The BAV19WS-G RRG, BAV19WS-TP, and BAV19WSHE3-TP are parametric equivalents with identical or superior electrical specifications. All maintain the 100 V reverse voltage, 200 mA current rating, 1.25 V forward voltage, 50 ns reverse recovery time, 100 nA reverse leakage current, and -65°C to 150°C junction temperature range. The BAV19WS-TP and BAV19WSHE3-TP feature lower capacitance (1.5 pF vs. 5 pF), which may provide improved high-frequency performance. All are active in production and ROHS3 compliant.

Q: What is the significance of the AEC-Q101 qualification on the BAV19WSHE3-TP?

A: AEC-Q101 is an automotive electronics qualification standard. The BAV19WSHE3-TP carries this qualification, making it suitable for automotive applications where component reliability and traceability are required. If the original design is for automotive use, the BAV19WSHE3-TP is the appropriate substitute choice.
