HS5A Equivalent & Substitute Parts Reference

Part Overview

The HS5A is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 5 A average rectified current in a DO-214AB surface mount package. This component is classified as a fast recovery diode with a reverse recovery time of 50 ns, suitable for applications requiring rapid switching characteristics. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary HS5A variant experiences supply constraints, packaging format changes, or when alternative sourcing from qualified manufacturers is required for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS5A is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage - DC Reverse (Vr) Maximum: 50 V
• Current - Average Rectified (Io): 5 A
• Package / Case: DO-214AB (SMC)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Packaging format (Tape & Reel, Cut Tape, or unspecified)
• Voltage - Forward (Vf) Maximum: up to 1.15 V @ 5 A
• Reverse Recovery Time (trr): up to 2.5 µs (standard recovery acceptable)
• Capacitance @ Vr, F: 40 pF to 80 pF range
• Product Status: Active or Discontinued at DiGi Electronics

Parametric equivalents (HS5A R7G, HS5A V7G) maintain identical electrical specifications and differ only in packaging format. Similar equivalents (S5A-E3/57T) meet all mandatory parameters but exhibit relaxed recovery time characteristics and reduced forward voltage performance, classifying them as functional alternatives rather than direct replacements.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes):

HS5A R7G and HS5A V7G are parametric equivalents of the HS5A, maintaining identical electrical performance across all critical specifications. Both parts are manufactured by Taiwan Semiconductor Corporation and carry ROHS3 compliance. Selection between these variants is determined by packaging format requirements: HS5A R7G is supplied in Cut Tape format, while HS5A V7G packaging format is unspecified. Both variants are currently discontinued at DiGi Electronics, indicating limited future availability. These parts are suitable for direct substitution in applications where the original HS5A specification is required.

Similar Equivalent (Functional Alternative):

S5A-E3/57T, manufactured by Vishay General Semiconductor, meets all mandatory electrical and mechanical parameters but operates with standard recovery characteristics (2.5 µs reverse recovery time) rather than fast recovery (50 ns). This part exhibits higher forward voltage (1.15 V versus 1 V at 5 A) and lower junction capacitance (40 pF versus 80 pF). S5A-E3/57T is currently active in production with ROHS3 compliance and higher inventory availability (30,100 pieces). This part is suitable for applications where fast recovery performance is not critical and where the increased forward voltage drop is acceptable.

Compliance and Regulatory Status:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the regulatory profile of the primary HS5A component.

Frequently Asked Questions (FAQ)

Q: Can HS5A R7G and HS5A V7G be used interchangeably with the primary HS5A?

A: Yes. HS5A R7G and HS5A V7G are parametric equivalents with identical electrical specifications. The only differences are packaging format (Cut Tape versus Tape & Reel) and product discontinuation status. Selection depends on your assembly process requirements for tape format compatibility.

Q: What is the key difference between the HS5A and S5A-E3/57T?

A: The primary differences are recovery speed and forward voltage. The HS5A is a fast recovery diode (50 ns trr) with 1 V forward voltage, while S5A-E3/57T is a standard recovery diode (2.5 µs trr) with 1.15 V forward voltage. The HS5A is preferred for high-frequency switching applications; S5A-E3/57T is suitable for lower-frequency rectification where recovery speed is not critical.

Q: Are all substitute parts in the same DO-214AB package?

A: Yes. All listed substitute parts use the DO-214AB (SMC) surface mount package with identical mechanical dimensions and land pattern compatibility.

Q: What is the impact of the 0.15 V forward voltage difference between HS5A and S5A-E3/57T?

A: At 5 A rated current, the S5A-E3/57T dissipates an additional 0.75 W compared to the HS5A (0.15 V × 5 A). This increased power dissipation may require thermal management evaluation in high-current or high-frequency applications.

Q: Can I use S5A-E3/57T in a circuit designed for fast recovery diodes?

A: S5A-E3/57T can be used in circuits where the application does not require fast recovery switching characteristics. The 2.5 µs reverse recovery time is significantly slower than the 50 ns specification of the HS5A. Verify that your circuit topology and switching frequency are compatible with standard recovery performance before substitution.

Q: What is the current inventory status for these parts?

A: HS5A (931 pieces), HS5A R7G (860 pieces), HS5A V7G (2,075 pieces), and S5A-E3/57T (30,100 pieces) are listed as new original stock. HS5A R7G and HS5A V7G are discontinued at DiGi Electronics, indicating limited future availability.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1) and REACH unaffected status.
