BAS16SL Equivalent & Substitute Parts

Part Overview

The BAS16SL is a general-purpose rectifier diode manufactured by onsemi, rated for 85 V DC reverse voltage and 150 mA average rectified current in a surface mount SOD-923F package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The BAS16SL serves applications requiring small-signal rectification, switching, and general-purpose diode functions in compact surface mount form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS16SL is determined by electrical and mechanical compatibility within the following criteria:

Electrical Parameters:

• Voltage - DC Reverse (Vr) must equal or exceed 85 V
• Current - Average Rectified (Io) must equal or exceed 150 mA
• Voltage - Forward (Vf) must be compatible at rated current
• Operating temperature range must encompass -55°C to 150°C

Mechanical Parameters:

• Package / Case must be surface mount compatible
• Mounting type must be surface mount
• Physical footprint must accommodate SOD-923 or equivalent compact form factors

Compliance Parameters:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required
• REACH Unaffected status required

Two substitute parts meet these criteria: BAS16P2T5G (direct manufacturer equivalent from onsemi) and BAS16L-G3-08 (similar part from Vishay General Semiconductor - Diodes Division). Both parts exceed the minimum electrical requirements and maintain full compliance with environmental and regulatory standards.

Engineering Selection Recommendations

BAS16P2T5G (Direct Equivalent)

The BAS16P2T5G is the primary substitute for the obsolete BAS16SL. Both parts share the same base product number (BAS16) and are manufactured by onsemi. The BAS16P2T5G is currently in active production with 21,100 pieces in stock. It provides higher voltage (100 V vs. 85 V) and current (200 mA vs. 150 mA) ratings while maintaining identical forward voltage characteristics. The package remains SOD-923, ensuring direct mechanical compatibility. This part is recommended for applications requiring minimal design modification and maximum supply chain continuity.

BAS16L-G3-08 (Alternative Substitute)

The BAS16L-G3-08 is manufactured by Vishay General Semiconductor - Diodes Division and offers superior electrical performance with 100 V reverse voltage, 250 mA current rating, and faster reverse recovery time (4 ns vs. 8 ns). This part uses a DFN1006-2A package (0402 metric equivalent), which is physically smaller than SOD-923 but requires PCB layout modification. The BAS16L-G3-08 is currently in active production with 10,828 pieces in stock. This part is suitable for applications where improved switching speed and reduced capacitance are beneficial and where PCB redesign is acceptable.

Both substitute parts maintain full ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory and environmental compatibility with the original BAS16SL specification.

Frequently Asked Questions (FAQ)

Q: Can BAS16P2T5G be used as a direct replacement for BAS16SL without PCB modification?

A: Yes. The BAS16P2T5G maintains the same SOD-923 package and pinout as the BAS16SL. No PCB layout changes are required. The higher voltage and current ratings provide additional design margin.

Q: What is the primary difference between BAS16P2T5G and BAS16L-G3-08?

A: The BAS16P2T5G uses SOD-923 packaging (same as BAS16SL), while BAS16L-G3-08 uses DFN1006-2A packaging (0402 metric). The BAS16L-G3-08 offers faster reverse recovery time (4 ns vs. 6 ns) and lower capacitance (0.36 pF vs. 2 pF). Package selection depends on PCB design constraints and performance requirements.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both BAS16P2T5G and BAS16L-G3-08 are ROHS3 compliant with MSL 1 (Unlimited) rating and REACH Unaffected status, matching the environmental compliance of the original BAS16SL.

Q: What is the reverse leakage current difference between BAS16P2T5G and BAS16L-G3-08?

A: BAS16P2T5G has 100 µA reverse leakage at 100 V, while BAS16L-G3-08 has 1 µA reverse leakage at 100 V. For applications sensitive to leakage current, BAS16L-G3-08 is the superior choice.

Q: Can I use BAS16L-G3-08 in existing BAS16SL PCB designs?

A: No. BAS16L-G3-08 uses DFN1006-2A packaging, which has a different footprint than SOD-923. PCB layout modification is required. BAS16P2T5G is the recommended choice for direct PCB compatibility.

Q: What is the operating temperature range for both substitute parts?

A: Both BAS16P2T5G and BAS16L-G3-08 operate from -55°C to 150°C junction temperature, matching the BAS16SL specification.

Q: Which substitute part has better switching performance?

A: BAS16L-G3-08 has superior switching performance with 4 ns reverse recovery time compared to 6 ns for BAS16P2T5G and 8 ns for BAS16SL. This faster recovery time reduces switching losses in high-frequency applications.
