BAS16 Equivalent & Substitute Parts

Part Overview

The BAS16 is a small signal general-purpose diode manufactured by onsemi in a surface mount SOT-23-3 package. The original BAS16 is classified as obsolete product status, with a maximum reverse voltage rating of 75 V and average rectified current of 150 mA. The device operates across a junction temperature range of -55°C to 150°C and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Due to the obsolete status of the original BAS16, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. The substitute parts listed maintain functional compatibility within specified electrical and mechanical parameters while offering active product status from multiple semiconductor manufacturers.

Substitute Part Grouping Explanation

Substitution of the BAS16 is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: Substitute parts must maintain a DC reverse voltage (Vr) rating equal to or greater than the original 75 V specification. Parts with higher voltage ratings (80 V, 100 V) are acceptable for applications requiring the original 75 V rating.

Current Rating Compatibility: Substitute parts must support an average rectified current (Io) equal to or greater than the original 150 mA specification. Parts rated for 200 mA, 250 mA, or 300 mA are acceptable.

Package Compatibility: All substitute parts must use the SOT-23-3 package format (also designated TO-236-3 or SC-59) to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Temperature Range: Substitute parts must support the operating junction temperature range of -55°C to 150°C or equivalent.

Compliance Requirements: All substitute parts must maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity level to meet regulatory and manufacturing requirements.

Speed Classification: Substitute parts classified as small signal (≤200 mA) or fast recovery (>200 mA) are both acceptable, as the original BAS16 operates within the small signal category.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Matched Specifications):

BAS16-E3-08 from Vishay General Semiconductor provides the closest electrical match to the original BAS16, with identical 75 V reverse voltage and 150 mA current ratings in active product status. This part is recommended for direct replacement in existing designs.

BAS16-7-F from Diodes Incorporated offers 75 V reverse voltage with increased current capacity (300 mA) while maintaining active product status and the same 4 ns reverse recovery time as the original.

BAS16_R1_00001 from Panjit International Inc. maintains the original 75 V voltage rating with increased current capacity (250 mA) and active product status.

Secondary Substitutes (Active Status, Enhanced Specifications):

BAS16LT1G and BAS16LT3G from onsemi provide increased voltage rating (100 V) and current capacity (200 mA) with active product status. These parts are suitable for applications requiring higher voltage margins.

BAS16-TP from Micro Commercial Co offers 100 V reverse voltage with 300 mA current capacity in active status, providing enhanced performance headroom.

BAS16-G from Comchip Technology provides 75 V voltage rating with 200 mA current capacity in active status.

Alternative Substitutes (Last Time Buy Status):

BAS16E6327HTSA1 and BAS16E6433HTMA1 from Infineon Technologies offer 80 V reverse voltage with 250 mA current capacity. These parts are classified as Last Time Buy status and should be evaluated for long-term supply chain considerations.

PMBD6050,215 from NXP Semiconductors provides 70 V reverse voltage with 215 mA current capacity in active status. This part operates at the lower end of voltage specification and should be selected only when the 70 V rating is confirmed acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can BAS16LT1G be used as a direct replacement for BAS16?

A: BAS16LT1G is electrically compatible with BAS16 for applications operating at or below 75 V. The higher 100 V rating provides additional voltage margin. The increased current capacity (200 mA vs. 150 mA) and identical SOT-23-3 package ensure mechanical and thermal compatibility. Forward voltage characteristics differ slightly (1.25 V @ 150 mA vs. 855 mV @ 10 mA), which may affect circuit performance in precision applications.

Q: What is the difference between BAS16-E3-08 and the original BAS16?

A: BAS16-E3-08 from Vishay matches the original BAS16 specifications exactly: 75 V reverse voltage, 150 mA current rating, and SOT-23-3 package. The primary difference is active product status versus obsolete status. Reverse recovery time differs slightly (6 ns vs. 4 ns), and forward voltage is specified at 1.25 V @ 150 mA rather than 855 mV @ 10 mA.

Q: Are all substitute parts available in the same package?

A: All listed substitute parts use the SOT-23-3 package (also designated TO-236-3 or SC-59), ensuring mechanical compatibility with existing PCB layouts. Packaging formats vary (Cut Tape, Tape & Reel, Bulk), but the physical component package remains consistent.

Q: Which substitute part has the lowest forward voltage drop?

A: BAS16_R1_00001 specifies forward voltage at 855 mV @ 10 mA, matching the original BAS16 specification. Other substitute parts specify forward voltage at 1.25 V @ 150 mA, which represents a different measurement condition and cannot be directly compared without circuit analysis.

Q: Can I use BAS16-TP in place of BAS16 if my circuit operates below 75 V?

A: BAS16-TP is electrically compatible with BAS16 for circuits operating below 75 V. The part provides 100 V reverse voltage rating and 300 mA current capacity, both exceeding original specifications. The SOT-23-3 package ensures mechanical compatibility. Reverse recovery time is 4 ns (matching the original), and forward voltage is 1.25 V @ 100 mA.

Q: What is the significance of "Last Time Buy" status for Infineon parts?

A: Last Time Buy status indicates that Infineon Technologies will discontinue these parts after a specified date. BAS16E6327HTSA1 and BAS16E6433HTMA1 should be evaluated for long-term supply chain requirements. For new designs requiring extended product availability, active status parts such as BAS16-E3-08, BAS16-7-F, or BAS16LT1G are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts maintain RoHS3 compliance and MSL 1 (unlimited) moisture sensitivity level, meeting regulatory requirements equivalent to the original BAS16.

Q: What is the difference between BAS16LT1G and BAS16LT3G?

A: BAS16LT1G and BAS16LT3G are electrically identical, both offering 100 V reverse voltage and 200 mA current capacity in SOT-23-3 package. The difference is in manufacturing date code or internal lot designation. Both are active status parts from onsemi suitable for BAS16 replacement.

Q: Can PMBD6050,215 be used as a substitute if my application requires 75 V rating?

A: PMBD6050,215 is rated for 70 V maximum reverse voltage, which is below the original BAS16 specification of 75 V. This part should be selected only when circuit analysis confirms that 70 V rating is acceptable for the specific application. The part provides 215 mA current capacity and active product status.
