HS2BA Equivalent & Substitute Parts

Part Overview

The HS2BA is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1.5 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as a fast recovery diode with a reverse recovery time of 50 ns, suitable for standard rectification applications requiring moderate voltage and current ratings.

The HS2BA is currently Active in product status with 1029 pieces available in inventory. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support component selection based on packaging preferences and manufacturer availability.

Parameter Comparison

Engineering Selection Recommendations

HS2BA (Primary Part) The HS2BA is the primary reference component, currently Active in product status with moderate inventory availability. This part is suitable for new designs and ongoing production requiring Tape & Reel packaging.

US2BA (Recommended Substitute) The US2BA manufactured by Fairchild Semiconductor is a parametric equivalent meeting all electrical and mechanical specifications. This part is Active in product status with significantly higher inventory (39600 pieces), making it suitable for high-volume applications. The US2BA carries AEC-Q101 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Packaging is supplied in Bulk format, which may require reeling for automated assembly processes.

HS2BA R3G (Alternative Substitute) The HS2BA R3G is a parametric equivalent from Taiwan Semiconductor Corporation meeting all electrical and mechanical specifications. This part is Discontinued at DiGi Electronics and should be considered only when existing inventory must be utilized or when Cut Tape packaging is specifically required. New designs should prioritize the primary HS2BA or the US2BA substitute.

Frequently Asked Questions (FAQ)

Q: Can the US2BA be used as a direct replacement for the HS2BA? A: Yes. The US2BA meets all electrical parameters (100 V reverse voltage, 1.5 A average rectified current, 50 ns reverse recovery time, 1 V forward voltage drop) and is packaged in the same DO-214AC (SMA) surface mount configuration. The primary difference is packaging format (Bulk versus Tape & Reel) and manufacturer (Fairchild Semiconductor versus Taiwan Semiconductor Corporation).

Q: What is the difference between Tape & Reel, Cut Tape, and Bulk packaging? A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides the same tape format but in shorter lengths for lower-volume applications. Bulk packaging supplies loose components without tape, requiring manual handling or external reeling for automated assembly. All three formats contain identical components with identical electrical specifications.

Q: Is the HS2BA R3G still available for new designs? A: The HS2BA R3G is Discontinued at DiGi Electronics and should not be specified for new designs. The primary HS2BA or the US2BA substitute are recommended for ongoing production and new product development.

Q: Does the US2BA automotive qualification affect its use in non-automotive applications? A: No. AEC-Q101 qualification indicates the component meets automotive reliability standards and is suitable for all applications, including non-automotive use. Automotive-qualified components typically undergo more rigorous testing and screening, providing equivalent or superior performance in any application.

Q: Are there any thermal or performance differences between these substitutes? A: All three parts share identical electrical specifications including reverse recovery time (50 ns), forward voltage drop (1 V @ 1.5 A), and operating temperature range (-55°C to 150°C). Performance in circuit operation is equivalent across all three parts.

Q: What compliance certifications apply to these parts? A: All three parts are ROHS3 Compliant and REACH Unaffected. The HS2BA and HS2BA R3G carry Moisture Sensitivity Level 1 (Unlimited). The US2BA does not specify MSL but is suitable for standard handling and storage conditions.
