BAS16 Equivalent & Substitute Parts

Part Overview

The BAS16 is a general-purpose switching diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOT-23 package. This component operates at 75V reverse voltage with a 150mA average rectified current rating and features a 4ns reverse recovery time, making it suitable for high-speed switching applications. The part is currently in active production status with RoHS3 compliance and REACH unaffected classification. Substitute parts are identified to address inventory availability, extended voltage ratings, or higher current capacity requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS16 is determined by the following critical parameters: package compatibility (TO-236-3/SOT-23-3), mounting type (surface mount), voltage rating (minimum 75V DC reverse), current capacity (minimum 150mA average rectified), and compliance certifications (RoHS3, REACH unaffected). Substitute parts must maintain or exceed the electrical specifications of the main part while operating within the same physical footprint. The identified substitutes are grouped based on their ability to meet these criteria while offering variations in current capacity, voltage rating, or reverse recovery characteristics.

Parameter Comparison

Engineering Selection Recommendations

BAS116LT1G (onsemi): This substitute provides identical voltage and forward voltage characteristics to the main BAS16 part while offering increased current capacity at 200mA. The part is in active production status with ROHS3 compliance and MSL rating of 1 (Unlimited). The reverse recovery time specification differs at 3µs compared to the main part's 4ns, and reverse leakage current is reduced to 5nA. This substitute is suitable for applications requiring higher current handling within the same voltage envelope. Operating temperature range is -55 to 150°C.

BAS16 (Infineon Technologies): This substitute offers an elevated voltage rating of 85V with increased current capacity at 200mA, maintaining identical forward voltage characteristics. The part features a 6ns reverse recovery time and is packaged identically to the main part. However, this substitute carries an obsolete product status designation, indicating it is no longer in active production. ROHS3 compliance is maintained. Operating temperature range is -55 to 150°C. Selection of this part should account for its discontinued status and potential future supply constraints.

Frequently Asked Questions (FAQ)

Q: Can BAS116LT1G be used as a direct replacement for BAS16?

A: BAS116LT1G is electrically compatible with BAS16 in applications operating at 75V or below with current requirements up to 150mA. Both parts share identical package geometry (SOT-23-3), forward voltage characteristics, and capacitance specifications. The primary differences are increased current capacity (200mA vs 150mA) and different reverse recovery time (3µs vs 4ns). Selection depends on circuit requirements for reverse recovery performance.

Q: What is the impact of the different reverse recovery times between BAS16 and BAS116LT1G?

A: Reverse recovery time (trr) affects switching speed in high-frequency applications. BAS16 specifies 4ns while BAS116LT1G specifies 3µs. The BAS16 exhibits faster switching characteristics. In applications where reverse recovery time is not a critical parameter, BAS116LT1G operates identically. In high-frequency switching circuits, the faster recovery time of BAS16 may be required.

Q: Is the Infineon BAS16 substitute recommended for new designs?

A: The Infineon BAS16 carries an obsolete product status, indicating discontinued production. While it meets electrical and mechanical specifications, its use in new designs is not recommended due to supply availability constraints. The onsemi BAS116LT1G or the Taiwan Semiconductor BAS16 are preferred alternatives for active production status.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts listed carry ROHS3 compliance certification. All parts are also REACH unaffected. These certifications ensure compliance with environmental and hazardous substance regulations for electronic components.

Q: What is the difference in operating temperature range between the main part and substitutes?

A: The Taiwan Semiconductor BAS16 operates from -65 to 150°C junction temperature. Both the onsemi BAS116LT1G and Infineon BAS16 operate from -55 to 150°C. The main part provides an extended lower temperature operating range of 10°C. Selection should account for application requirements in low-temperature environments.

Q: Can BAS116LT1G handle higher current than the original BAS16?

A: Yes, BAS116LT1G is rated for 200mA average rectified current compared to BAS16's 150mA rating. In applications requiring current levels between 150mA and 200mA, BAS116LT1G provides additional headroom. Both parts maintain identical forward voltage characteristics at 150mA measurement point.

Q: Are the package dimensions identical across all three parts?

A: Yes, all three parts use the TO-236-3/SC-59/SOT-23-3 package designation, ensuring identical physical footprint and pin configuration. Surface mount placement and soldering procedures are interchangeable across all three parts.
