BAS20-TP Equivalent & Substitute Parts

Part Overview

The BAS20-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 150 V DC reverse voltage and 200 mA average rectified current in a surface mount SOT-23 package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility across multiple manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the BAS20-TP are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications: 150 V reverse voltage, 200 mA average rectified current, 1.25 V forward voltage drop at 200 mA, 50 ns reverse recovery time, and SOT-23 package compatibility. These parts are direct functional replacements with no derating required.

Similar Parts share the same base product family (BAS20 or BAS21 series) and SOT-23 package but may differ in one or more electrical parameters. Parts with higher voltage ratings (200 V) or higher current ratings (250 mA) are suitable for applications where the BAS20-TP specifications represent minimum requirements. Parts with different supplier device packages (TO-236AB, SOT-23F) maintain mechanical compatibility with standard SOT-23 footprints.

The critical parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): must equal or exceed 150 V
Current - Average Rectified (Io): must equal or exceed 200 mA
Reverse Recovery Time (trr): must equal 50 ns
Package / Case: must be compatible with TO-236-3, SC-59, or SOT-23-3 footprints
Mounting Type: must be Surface Mount

Engineering Selection Recommendations

Direct Parametric Equivalents (BAS20HE3-TP, BAS20 RFG, BAS20Q-13-F, BAS20,215, BAS20,235, BAS20-7-F) provide identical electrical performance and are suitable for one-to-one replacement. BAS20HE3-TP and BAS20Q-13-F include AEC-Q101 automotive qualification, appropriate for applications requiring automotive-grade components. All parametric equivalents maintain Active product status and ROHS3 compliance.

Higher Voltage Rated Alternatives (BAS20LT1G, BAS21-7-F) are rated for 200 V reverse voltage while maintaining 200 mA current capacity. These parts operate within the same thermal and frequency characteristics and are suitable for designs where voltage margin is beneficial. BAS20LT1G operates at a minimum junction temperature of -55°C compared to -65°C for the main part.

Higher Current Rated Alternative (BAS21E6327HTSA1) is rated for 250 mA average rectified current at 200 V reverse voltage. This part carries Last Time Buy status and should be evaluated for long-term availability. The higher current rating provides design margin for applications approaching 200 mA limits.

Package Considerations: Parts designated with SOT-23F (flat leads) or TO-236AB supplier packages maintain mechanical compatibility with standard SOT-23 footprints. Verify PCB assembly equipment compatibility with specific lead geometry if transitioning between package variants.

Frequently Asked Questions (FAQ)

Q: Can BAS20LT1G be used as a direct replacement for BAS20-TP?

A: BAS20LT1G is electrically compatible with higher voltage rating (200 V vs. 150 V) and identical current capacity (200 mA). The part is suitable for replacement in applications where the 150 V specification represents a minimum requirement. The operating temperature range differs slightly (-55°C to 150°C vs. -65°C to 150°C); verify minimum temperature requirements for your application.

Q: What is the difference between BAS20,215 and BAS20,235?

A: Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications (150 V, 200 mA, 1.25 V forward voltage, 50 ns recovery time). The part numbers reflect different manufacturing codes or date codes. Both are suitable substitutes for BAS20-TP with no functional distinction.

Q: Is BAS21E6327HTSA1 suitable for BAS20-TP replacement?

A: BAS21E6327HTSA1 meets all electrical requirements with higher voltage (200 V) and current (250 mA) ratings. However, this part carries Last Time Buy status, indicating discontinued production. Use only if long-term supply is secured or as a temporary solution pending transition to an Active status alternative.

Q: What is the significance of the SOT-23F package designation on BAS20-7-F?

A: SOT-23F indicates flat lead geometry within the SOT-23 package family. The part maintains mechanical compatibility with standard SOT-23 footprints. Verify that your PCB assembly process and pick-and-place equipment support flat lead handling if transitioning from standard SOT-23 leads.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance profile of BAS20-TP.

Q: Can BAS20HE3-TP be used in automotive applications?

A: BAS20HE3-TP carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. BAS20-TP does not specify automotive qualification; verify your application requirements before selecting the automotive-qualified variant.

Q: What is the minimum voltage rating required for a substitute part?

A: Substitute parts must have a reverse voltage rating equal to or exceeding 150 V. Parts rated for 200 V (BAS20LT1G, BAS21-7-F, BAS21E6327HTSA1) are acceptable and provide additional voltage margin.

Q: What is the minimum current rating required for a substitute part?

A: Substitute parts must have an average rectified current rating equal to or exceeding 200 mA. BAS21E6327HTSA1 rated for 250 mA is acceptable and provides additional current margin.
