Engineering Selection Recommendations
For Direct Replacement with Enhanced Current Capacity: BAS16-7-F, BAS16Q-13-F, BAS16Q-7-F, MMBD4148-7-F, and MMBD914-7-F from Diodes Incorporated are active products with identical voltage and forward voltage specifications. These parts provide 300 mA current rating, exceeding the original 200 mA specification. All are RoHS3 compliant and suitable for new designs. BAS16Q-13-F and BAS16Q-7-F carry AEC-Q101 automotive qualification.
For Exact Current Rating Match: BAS116LT1G (onsemi), BAS16-G (Comchip Technology), and BAS16-HE3-18 (Vishay) maintain the 200 mA current specification. BAS116LT1G and BAS16-G are active products with RoHS3 compliance. BAS16-HE3-18 is classified as Last Time Buy. All three are suitable for applications requiring the original current specification.
For Enhanced Voltage Margin: BAS16,215 (Nexperia USA Inc.) and BAS16,235 (NXP Semiconductors) provide 100 V reverse voltage rating with 215 mA current capacity. Both are active products with RoHS3 compliance and AEC-Q101 automotive qualification. These parts are appropriate for designs requiring additional voltage transient protection.
Product Status Consideration: All substitute parts listed are either Active or Last Time Buy status, ensuring availability for current manufacturing. The original BAS16TA is obsolete and should be replaced in active designs.
Compliance Status: All substitute parts are RoHS3 compliant, addressing regulatory requirements not met by the original BAS16TA.
Frequently Asked Questions (FAQ)
Q: Can BAS16-7-F be used as a direct replacement for BAS16TA? A: Yes. BAS16-7-F maintains the same 75 V reverse voltage and 1.25 V forward voltage specifications. The 300 mA current rating exceeds the original 200 mA requirement, making it electrically compatible. Both use identical SOT-23-3 packaging. BAS16-7-F is an active product with RoHS3 compliance.
Q: What is the difference between BAS16Q-13-F and BAS16Q-7-F? A: Both parts have identical electrical specifications: 75 V, 300 mA, 1.25 V forward voltage, and 4 ns reverse recovery time. Both carry AEC-Q101 automotive qualification. The primary difference is packaging: BAS16Q-13-F is supplied in Tape & Reel (TR) format in 10K quantities, while BAS16Q-7-F packaging is not specified in the provided data. Both are active products suitable for automotive applications.
Q: Why would I choose BAS16,215 over BAS16-7-F? A: BAS16,215 provides 100 V reverse voltage rating compared to 75 V for BAS16-7-F. This higher voltage rating offers additional margin for transient protection in applications subject to voltage spikes. BAS16,215 also carries AEC-Q101 automotive qualification. The trade-off is a slightly higher current rating (215 mA vs. 300 mA) and different manufacturer (Nexperia vs. Diodes Incorporated).
Q: Is BAS16-HE3-18 suitable for new designs? A: BAS16-HE3-18 is classified as Last Time Buy, indicating the manufacturer is discontinuing production. While currently available, it is not recommended for new designs. Active alternatives such as BAS16-G (Comchip Technology) or BAS116LT1G (onsemi) are preferred for long-term supply assurance.
Q: Do all substitute parts use the same SOT-23-3 package? A: Yes. All substitute parts listed use the TO-236-3, SC-59, SOT-23-3 package, ensuring mechanical and electrical compatibility with the original BAS16TA footprint.
Q: What is the significance of RoHS3 compliance? A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. The original BAS16TA is RoHS non-compliant. All substitute parts are RoHS3 compliant, meeting current regulatory requirements for manufacturing and distribution in regulated markets.
Q: Can BAS16-G be used in automotive applications? A: BAS16-G is manufactured by Comchip Technology and is RoHS3 compliant with active product status. However, it does not carry AEC-Q101 automotive qualification. For automotive applications requiring qualification, BAS16Q-13-F, BAS16Q-7-F, BAS16,215, or BAS16,235 are appropriate choices.
Q: What is the difference in reverse recovery time between BAS16TA and its substitutes? A: BAS16TA has a 4 ns reverse recovery time. Diodes Incorporated substitutes (BAS16-7-F, BAS16Q series, MMBD series) maintain 4 ns. BAS116LT1G has 3 µs, and Comchip/Vishay parts have 6 ns. These differences reflect different diode speed classifications but do not affect compatibility in general-purpose rectifier applications.
Q: Are there inventory considerations when selecting a substitute? A: Yes. BAS16,235 (NXP Semiconductors) has the highest inventory at 1,942,791 pieces. BAS16Q-7-F has 158,300 pieces, and BAS16-7-F has 310,700 pieces. MMBD914-7-F has limited inventory at 1,376 pieces. Inventory levels should be considered for long-term supply planning.
