SS12L RHG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS12L RHG is a surface mount Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 20 V DC reverse voltage and 1 A average rectified current. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). The SS12L RHG is packaged in DO-219AB (Sub SMA) configuration for surface mount applications.

Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility. Alternative part numbers may be required due to inventory availability, packaging format differences, or product lifecycle transitions within the same electrical specification range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS12L RHG are identified through parametric equivalence based on the following critical selection criteria:

Electrical Compatibility Parameters:

• Voltage - DC Reverse (Vr) Maximum: 20 V (exact match required)
• Current - Average Rectified (Io): 1 A minimum (equal or higher acceptable)
• Voltage - Forward (Vf) Maximum @ If: 450 mV or lower (lower values acceptable)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 400 µA or lower @ 20 V

Mechanical Compatibility Parameters:

• Package / Case: DO-219AB (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature - Junction: -55°C to 125°C minimum range

Compliance Parameters:

• Technology: Schottky diode
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Substitute parts meeting all electrical and mechanical criteria are classified as parametric equivalents. Parts with higher current ratings or improved electrical characteristics (lower forward voltage, lower leakage current) are acceptable substitutes provided all other parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

SS12L (Tape & Reel) - Taiwan Semiconductor Corporation

This part is a parametric equivalent to the SS12L RHG with identical electrical specifications and package configuration. The primary difference is packaging format (Tape & Reel versus individual unit packaging) and product status designation (Not For New Designs). This part is suitable for replacement in existing production runs or inventory replenishment where the original packaging format is not a constraint. The "Not For New Designs" status indicates this part number may be subject to future discontinuation; however, electrical compatibility is complete.

SL02-GS08 - Vishay General Semiconductor - Diodes Division

This part is a parametric equivalent with enhanced electrical performance characteristics. The SL02-GS08 provides higher average rectified current (1.1 A versus 1 A), lower forward voltage (420 mV @ 1.1 A versus 450 mV @ 1 A), and lower reverse leakage current (250 µA @ 20 V versus 400 µA @ 20 V). The SL02-GS08 includes specified reverse recovery time (10 ns) and maintains Active product status. All mechanical and compliance parameters are compatible with the SS12L RHG. The SL02-GS08 is suitable for new designs and applications requiring improved thermal performance or lower power dissipation.

Frequently Asked Questions (FAQ)

Q: Can the SS12L (Tape & Reel) be used as a direct replacement for the SS12L RHG?

A: Yes. Both parts share identical electrical specifications (20 V, 1 A, 450 mV forward voltage, fast recovery speed) and the same DO-219AB package configuration. The difference is packaging format and product lifecycle status. The Tape & Reel version is suitable for high-volume production environments, while the SS12L RHG may be supplied in alternative packaging. Electrical performance and mechanical fit are equivalent.

Q: What are the advantages of using SL02-GS08 over SS12L RHG?

A: The SL02-GS08 offers three measurable improvements: higher current rating (1.1 A versus 1 A), lower forward voltage drop (420 mV versus 450 mV), and lower reverse leakage current (250 µA versus 400 µA). These characteristics result in reduced power dissipation and improved thermal efficiency. The SL02-GS08 maintains Active product status, making it suitable for new design implementations.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-219AB package configuration with identical pin assignments and mechanical dimensions. Surface mount placement and reflow soldering parameters are compatible across all three parts.

Q: What is the significance of the "Not For New Designs" status on the SS12L (Tape & Reel)?

A: This designation indicates the part is in the mature or declining phase of its product lifecycle. While the part remains fully functional and available in current inventory, the manufacturer may discontinue this part number in the future. For new product designs, the SL02-GS08 (Active status) or other Active-status alternatives are recommended to ensure long-term supply chain continuity.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are suitable for applications requiring these compliance certifications.

Q: What is the operating temperature range difference between the parts?

A: The SS12L RHG and SS12L (Tape & Reel) specify -55°C to 125°C junction temperature range. The SL02-GS08 specifies 125°C maximum junction temperature without a stated minimum. For applications requiring operation below 0°C, the SS12L RHG or SS12L (Tape & Reel) are the appropriate selections.

Q: Can these parts be used interchangeably in existing circuit boards?

A: Yes, provided the circuit board layout accommodates the DO-219AB package footprint. All three parts use identical package dimensions and pin configurations. No circuit board redesign is required for substitution.
