SS16LH Equivalent & Substitute Parts

Part Overview

The SS16LH is a 1A, 60V Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-123 package. This component is classified as not for new designs, indicating it has been superseded in the manufacturer's product line. The fast recovery characteristic (≤500ns at >200mA) and automotive-grade qualification (AEC-Q101) make this diode suitable for high-frequency rectification applications requiring low forward voltage drop. Identifying equivalent substitute parts is necessary for design continuity, inventory management, and sourcing optimization when the primary part becomes unavailable or when transitioning to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS16LH is determined by electrical and mechanical parameter equivalence within the Schottky rectifier diode category. The critical parameters governing substitution are:

Electrical Parameters:

• Reverse voltage rating: 60 V (maximum)
• Average rectified current: 1 A
• Forward voltage drop: 700 mV maximum at 1 A
• Recovery speed: Fast recovery ≤500ns at >200mA
• Reverse leakage current: Must not exceed specified limits for the application

Mechanical Parameters:

• Surface mount technology
• Package compatibility (SOD-123 or equivalent form factor)
• Automotive-grade qualification (AEC-Q101)
• Operating temperature range: -55°C to 150°C

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status

Substitute parts must maintain all electrical specifications within the stated tolerances and support the same operating temperature range. Package variations are permitted when they maintain mechanical compatibility with the PCB footprint and thermal performance requirements.

Parameter Comparison

Engineering Selection Recommendations

The SS16LWH serves as a direct electrical substitute for the SS16LH with the following considerations:

Electrical Equivalence: Both parts maintain identical voltage ratings (60 V reverse), current ratings (1 A average rectified), forward voltage characteristics (700 mV @ 1 A), and recovery speed specifications (≤500ns). The SS16LWH exhibits improved reverse leakage performance (100 µA versus 400 µA at 60 V), which represents a performance enhancement without introducing incompatibility.

Package Compatibility: The SS16LWH uses the SOD-123W package variant compared to the SS16LH's SOD-123 package. Both are surface mount packages with compatible footprints for standard PCB layouts. Verification of PCB footprint compatibility is required for specific board designs.

Compliance and Qualification: Both parts carry identical automotive-grade qualification (AEC-Q101), RoHS3 compliance, and REACH unaffected status, ensuring regulatory and quality requirements are maintained.

Product Status Advantage: The SS16LWH is classified as an active product, whereas the SS16LH is not recommended for new designs. Selection of the SS16LWH provides access to current manufacturing processes, improved supply chain availability, and ongoing manufacturer support.

Thermal Performance: Both parts operate across the identical temperature range (-55°C to 150°C junction temperature), supporting equivalent thermal design requirements.

Frequently Asked Questions (FAQ)

Q: Can the SS16LWH directly replace the SS16LH in existing designs?

A: Yes. The SS16LWH maintains all critical electrical parameters: 60 V reverse voltage, 1 A average rectified current, 700 mV forward voltage at 1 A, and fast recovery speed ≤500ns. The reverse leakage current is improved (lower) in the SS16LWH. PCB footprint compatibility must be verified, as the SOD-123W package is a variant of SOD-123.

Q: What is the difference between SOD-123 and SOD-123W packages?

A: Both are surface mount packages for Schottky rectifier diodes. SOD-123W is a wider variant of the SOD-123 package. Both support equivalent electrical performance and thermal characteristics. PCB layout and footprint design must accommodate the specific package variant selected.

Q: Why is the SS16LH marked as "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's active product portfolio. The SS16LWH is the current active equivalent, offering the same electrical specifications with improved reverse leakage performance and ongoing manufacturing support.

Q: Are there any performance differences between SS16LH and SS16LWH?

A: The primary difference is reverse leakage current: SS16LWH exhibits 100 µA at 60 V compared to 400 µA for the SS16LH. This represents improved performance in the substitute part. All other electrical parameters are identical.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the SS16LH and SS16LWH carry AEC-Q101 automotive-grade qualification and are suitable for automotive applications requiring Schottky rectifier diodes.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Is the SS16LWH available in the same packaging format (Tape & Reel)?

A: Yes. The SS16LWH is supplied in Tape & Reel (TR) packaging, matching the supply format of the SS16LH.
