HS1ML RVG Equivalent & Substitute Parts

Part Overview

The HS1ML RVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 1000 V DC reverse voltage and 1 A average rectified current. This surface mount component features fast recovery characteristics with a reverse recovery time of 75 ns and is housed in a Sub SMA (DO-219AB) package. The part is currently in active production status with 759 pieces available in cut tape packaging.

Substitute parts are necessary when cut tape packaging is unavailable, when higher operating temperature ranges are required, or when alternative package configurations better suit assembly requirements while maintaining electrical equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS1ML RVG is determined by the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
• Reverse Recovery Time (trr): 75 ns
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Operating Temperature - Junction: May extend beyond -55°C to 150°C range
• Package / Case: Alternative surface mount packages (DO-219AB, SOD-123W)
• Packaging Format: Cut Tape (CT) or Tape & Reel (TR)
• Current - Reverse Leakage @ Vr: May be lower than specified
• Capacitance @ Vr, F: May be lower than specified

The HS1MLW and HS1ML meet all critical matching parameters and are therefore qualified as substitutes for the HS1ML RVG.

Engineering Selection Recommendations

HS1MLW (Recommended Manufacturer Substitute): The HS1MLW is the manufacturer-recommended substitute for the HS1ML RVG. This part maintains all critical electrical parameters while offering an extended operating temperature range (-55°C to 175°C versus -55°C to 150°C). The HS1MLW is packaged in SOD-123W format with tape and reel delivery, providing higher inventory availability (10300 pieces). The part is in active production status and carries ROHS3 compliance and REACH unaffected certification. The HS1MLW exhibits lower reverse leakage current (1 µA versus 5 µA) and reduced capacitance (7 pF versus 15 pF), both favorable characteristics for general-purpose rectification applications.

HS1ML (Parametric Equivalent): The HS1ML is a parametric equivalent to the HS1ML RVG, maintaining identical electrical specifications and the same Sub SMA package format. However, this part carries a "Not For New Designs" product status designation, indicating it is in the mature or end-of-life phase of its lifecycle. The HS1ML is available in tape and reel packaging with 2200 pieces in inventory. This part is suitable only for replacement or maintenance applications where the original package format is required and new design qualification is not necessary.

Frequently Asked Questions (FAQ)

Q: Can the HS1MLW be used as a direct replacement for the HS1ML RVG in existing designs?

A: Yes. The HS1MLW meets all critical electrical parameters: 1000 V reverse voltage, 1 A average rectified current, 1.7 V forward voltage at 1 A, and 75 ns reverse recovery time. The primary difference is the package format (SOD-123W versus Sub SMA). PCB layout modifications are required to accommodate the different package geometry.

Q: What is the difference between the HS1MLW and HS1ML substitutes?

A: The HS1MLW and HS1ML are electrically equivalent to the HS1ML RVG in all critical parameters. The HS1MLW offers an extended operating temperature range (-55°C to 175°C) and is in active production status. The HS1ML is marked "Not For New Designs" and should be used only for replacement applications. Both are available in tape and reel packaging, while the HS1ML RVG is supplied in cut tape format.

Q: Does the lower reverse leakage current of the HS1MLW affect circuit performance?

A: Lower reverse leakage current (1 µA versus 5 µA) is a favorable characteristic that does not negatively impact circuit performance. This represents improved device quality and reduced power dissipation in reverse bias conditions.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. The HS1ML RVG, HS1MLW, and HS1ML are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging considerations apply when substituting the HS1MLW for the HS1ML RVG?

A: The HS1ML RVG is supplied in cut tape (CT) format, while the HS1MLW is supplied in tape and reel (TR) format. The HS1MLW uses a SOD-123W package instead of Sub SMA (DO-219AB). These differences require PCB layout redesign and assembly process adjustments. The HS1MLW provides significantly higher inventory availability (10300 pieces versus 759 pieces).

Q: Is the HS1ML suitable for new product designs?

A: No. The HS1ML carries a "Not For New Designs" product status. For new designs, the HS1MLW is the appropriate selection as it is in active production status and offers extended operating temperature range.
