Taiwan Semiconductor Corporation HS3A Diode Equivalent & Substitute Parts Reference

Part Overview

The HS3A by Taiwan Semiconductor Corporation is a general-purpose, fast recovery diode in the Diodes, Rectifiers category. It's specified for 50 V maximum reverse voltage, 3A average rectified current, and is supplied in the DO-214AB (SMC) surface mount package. The product is active and ROHS3 compliant, with an operating junction temperature of -55°C to +150°C. Sourcing alternative models is necessary when considering supply chain flexibility, discontinued part status, or allocation events for the HS3A, especially in high-volume production.

Key Parameters

Substitute Part Grouping Explanation

Parametric substitutes for HS3A in the Diodes, Rectifiers category are determined by exact matching of critical electrical and mechanical parameters. The key parameters include: manufacturer, voltage - DC reverse (Vr) (max), current - average rectified (Io), forward voltage (Vf) at test current, recovery speed classification, reverse recovery time (trr), reverse leakage current, capacitance, mounting type, package / case, and supplier device package. Substitute models listed are validated strictly on these attributes.

Parameter Comparison

Engineering Selection Recommendations

All compared diodes are ROHS3 compliant, feature Moisture Sensitivity Level 1 (unlimited), and have REACH Unaffected status. Product statuses indicate that HS3A is active, while HS3A R7G and HS3A V7G are discontinued at Digi-Key. Selection for compliant processes or enduring environmental certifications is supported by these parameters. For ongoing supply, refer to product status and current inventory details.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting Taiwan Semiconductor Corporation HS3A in a circuit?
A1: Substitution is based strictly on matching voltage - DC reverse (Vr) (max), average rectified current (Io), forward voltage (Vf) at the specified current, speed and recovery times, reverse leakage, capacitance, package style, mounting type, and compliance certifications.

Q2: Are the HS3A R7G and HS3A V7G pin-compatible and mechanically equivalent to HS3A?
A2: Yes. All parts feature the DO-214AB (SMC) package and are surface mount devices, ensuring mechanical and pin compatibility.

Q3: Does the product status impact interchangeability in existing designs?
A3: Product status such as "discontinued" affects long-term availability but does not change electrical or mechanical interchangeability given the parameters provided.

Q4: Is there any difference in environmental compliance between HS3A and its substitutes?
A4: No, all listed diodes are ROHS3 compliant and REACH Unaffected, supporting the same environmental or regulatory requirements.

Q5: What should be considered regarding packaging when seeking a substitute for HS3A?
A5: The main differences are in packaging such as Tape & Reel (TR) versus Cut Tape (CT). There is no impact on electrical or mechanical substitution if the package and device marking are equivalent.
