BAS16-D87Z Equivalent & Substitute Parts

Part Overview

The BAS16-D87Z is a general-purpose rectifier diode manufactured by onsemi, rated for 85 V DC reverse voltage and 200 mA average rectified current in a surface mount SOT-23-3 package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The BAS16 series provides a range of compatible alternatives across multiple manufacturers with varying electrical specifications suited to different application requirements.

Substitute Part Grouping Explanation

Substitution of the BAS16-D87Z is determined by compatibility across the following critical parameters: reverse voltage rating (Vr), average rectified current (Io), forward voltage (Vf), package type (SOT-23-3), and mounting configuration (surface mount). Substitute parts must maintain the same physical footprint and pin configuration to ensure direct board-level compatibility.

The substitute parts are grouped into two categories based on electrical performance:

Category 1: Direct Electrical Equivalents (100 V Rating) Parts with equal or higher reverse voltage ratings and matching current specifications provide direct substitution with enhanced voltage margin. These include BAS16LT3G and BAS16LT1G from onsemi, both rated at 100 V and 200 mA.

Category 2: Functional Alternatives (75 V - 80 V Rating) Parts with lower reverse voltage ratings but matching or higher current capacity serve applications where the 85 V specification exceeds circuit requirements. These include BAS16-7-F (Diodes Incorporated, 75 V / 300 mA), BAS16-E3-18 (Vishay, 75 V / 150 mA), BAS16-G (Comchip, 75 V / 200 mA), BAS16E6327HTSA1 (Infineon, 80 V / 250 mA), and PMBD6050 variants (NXP/Nexperia, 70 V / 215 mA).

Category 3: Enhanced Performance Alternatives (100 V Rating, Higher Current) Parts with higher current ratings and fast recovery characteristics support applications requiring improved thermal performance. BAS16-TP (Micro Commercial Co, 100 V / 300 mA) and BAS16E6433HTMA1 (Infineon, 80 V / 250 mA) fall into this category.

All substitute parts maintain SOT-23-3 package compatibility, surface mount configuration, and operating temperature range of -55°C to 150°C or better.

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs)

BAS16LT3G and BAS16LT1G from onsemi are the preferred substitutes for the obsolete BAS16-D87Z. Both parts are active products with identical electrical specifications to the original part, except for a 15 V higher reverse voltage rating (100 V vs. 85 V). This increased voltage margin provides enhanced reliability in applications with transient overvoltage conditions. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing processes.

Secondary Substitutes (Functional Alternatives)

BAS16-7-F (Diodes Incorporated) and BAS16-TP (Micro Commercial Co) are suitable for applications where higher current capacity is beneficial. BAS16-7-F provides 300 mA current rating with 75 V reverse voltage and fast recovery characteristics (4 ns trr). BAS16-TP offers 100 V reverse voltage with 300 mA current and fast recovery performance. Both are active products with ROHS3 compliance.

BAS16-G (Comchip Technology) provides an exact current match (200 mA) at 75 V reverse voltage with standard recovery time (6 ns), suitable for cost-optimized applications where the lower voltage rating is acceptable.

Last Time Buy Alternatives

BAS16E6327HTSA1 and BAS16E6433HTMA1 from Infineon Technologies are classified as Last Time Buy products. These parts offer 80 V reverse voltage and 250 mA current with fast recovery characteristics. Selection of these parts should be limited to applications requiring their specific performance characteristics, as future availability is limited.

Lower Voltage Alternatives

PMBD6050,215 and PMBD6050,235 from NXP Semiconductors and Nexperia USA Inc. respectively are rated at 70 V reverse voltage with 215 mA current. These parts are suitable only for applications where the 70 V specification meets circuit requirements, as they provide the lowest voltage margin among available substitutes.

Frequently Asked Questions (FAQ)

Q: Can BAS16LT3G directly replace BAS16-D87Z without circuit modification?

A: Yes. BAS16LT3G is a direct replacement with identical current rating (200 mA), matching forward voltage (1.25 V @ 150 mA), and identical reverse recovery time (6 ns). The 100 V reverse voltage rating exceeds the original 85 V specification, providing additional voltage margin. No circuit modifications are required.

Q: What is the difference between BAS16LT3G and BAS16LT1G?

A: Both parts are electrically identical with 100 V reverse voltage and 200 mA current ratings. The difference lies in packaging: BAS16LT3G is supplied in Cut Tape (CT) & Digi-Reel format, while BAS16LT1G is also supplied in Cut Tape & Digi-Reel format. Both are active products with significantly higher inventory availability (18,150 and 665,100 units respectively).

Q: Can I use BAS16-E3-18 as a substitute if my circuit only requires 150 mA?

A: BAS16-E3-18 is suitable for applications requiring 150 mA or less. However, it is rated at 75 V reverse voltage compared to the original 85 V specification. Selection depends on whether the 75 V rating provides sufficient voltage margin for your specific application. The part is active and ROHS3 compliant.

Q: What is the advantage of BAS16-7-F over BAS16-D87Z?

A: BAS16-7-F provides higher current capacity (300 mA vs. 200 mA) and faster reverse recovery time (4 ns vs. 6 ns), making it suitable for applications requiring improved thermal performance or faster switching. The reverse voltage rating is 75 V, which is lower than the original 85 V specification.

Q: Are all substitute parts available in the same SOT-23-3 package?

A: Yes. All listed substitute parts use the SOT-23-3 package (also designated TO-236-3 or SC-59), ensuring identical physical footprint and pin configuration for direct board-level compatibility.

Q: Should I consider Infineon's BAS16E6327HTSA1 for new designs?

A: BAS16E6327HTSA1 is classified as Last Time Buy, indicating limited future availability. For new designs, onsemi's BAS16LT3G or BAS16LT1G are preferred due to active product status and superior inventory availability. BAS16E6327HTSA1 should be reserved for applications requiring its specific 80 V / 250 mA performance characteristics where other alternatives are unsuitable.

Q: What is the difference between PMBD6050,215 and PMBD6050,235?

A: Both parts are electrically identical with 70 V reverse voltage and 215 mA current rating. PMBD6050,215 is supplied by NXP Semiconductors in Bulk packaging, while PMBD6050,235 is supplied by Nexperia USA Inc. in Tape & Reel (TR) format. Both are active products with ROHS3 compliance.

Q: Can I use a 75 V rated diode in a circuit designed for 85 V?

A: Substitution with a 75 V rated part depends on circuit design margins and transient overvoltage conditions. If the circuit includes protection against overvoltage transients or operates with significant voltage margin below 75 V, substitution is acceptable. If the circuit regularly operates near 85 V or experiences transient overvoltages, a 100 V rated part such as BAS16LT3G is recommended.

Q: What does "Last Time Buy" status mean for BAS16E6327HTSA1?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this product. Existing inventory may be available for a limited period, but no new production is planned. For long-term supply chain stability, active products such as BAS16LT3G or BAS16LT1G are recommended for new designs.
