SS22L M2G Equivalent & Substitute Parts

Part Overview

The SS22L M2G is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at a maximum reverse voltage of 20 V with an average rectified current rating of 2 A and a forward voltage drop of 500 mV at 2 A. The device exhibits fast recovery characteristics with a recovery time of ≤ 500 ns for currents exceeding 200 mA. Substitute parts are identified to address inventory availability, extended lead times, or specific application requirements while maintaining electrical and mechanical compatibility within defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS22L M2G is determined by the following critical parameters:

Mandatory Matching Criteria:

• Technology classification: Schottky diode
• Voltage rating: 20 V DC reverse maximum
• Package format: DO-219AB (Sub SMA / SMF equivalent)
• Mounting type: Surface Mount
• Fast recovery speed: ≤ 500 ns for currents > 200 mA
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Parameter Variance:

• Current - Average Rectified (Io): Substitute must equal or exceed 2 A rating
• Voltage - Forward (Vf): Substitute forward voltage must not exceed 500 mV @ rated current
• Current - Reverse Leakage: Substitute leakage must not exceed 400 µA @ 20 V
• Operating Temperature Range: Substitute maximum junction temperature must support application requirements

The SL02-GS08 from Vishay General Semiconductor - Diodes Division meets the mandatory matching criteria for voltage rating, package format, technology, and compliance standards. However, the current rating of 1.1 A is below the 2 A specification of the main part, restricting its use to applications requiring ≤ 1.1 A average rectified current.

Engineering Selection Recommendations

SS22L M2G Selection Criteria: The SS22L M2G is the primary component choice for applications requiring a 20 V, 2 A Schottky rectifier diode in DO-219AB surface mount package. This part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory conformance. The 2 A current rating and 500 mV forward voltage specification define the baseline performance envelope for this application class.

SL02-GS08 Substitution Constraints: The SL02-GS08 from Vishay General Semiconductor - Diodes Division is electrically compatible only for applications where the average rectified current requirement does not exceed 1.1 A. This substitute part shares identical voltage rating (20 V), package format (DO-219AB), technology classification (Schottky), and compliance certifications (ROHS3, MSL 1). The SL02-GS08 exhibits superior forward voltage characteristics (420 mV @ 1.1 A versus 500 mV @ 2 A) and lower reverse leakage current (250 µA versus 400 µA @ 20 V). However, the maximum junction temperature rating of 125°C is 25°C lower than the SS22L M2G specification of 150°C, which may restrict use in high-temperature operating environments.

Substitution Applicability: The SL02-GS08 is a valid substitute only when circuit design specifications permit operation at or below 1.1 A average rectified current and 125°C maximum junction temperature. Both parts maintain active product status and identical compliance certifications, supporting interchangeability within these defined electrical boundaries.

Frequently Asked Questions (FAQ)

Q: Can the SL02-GS08 replace the SS22L M2G in all applications?

A: No. The SL02-GS08 is limited to applications requiring ≤ 1.1 A average rectified current. The SS22L M2G is rated for 2 A, making it the required choice for higher current applications. Additionally, the SL02-GS08 maximum junction temperature of 125°C restricts its use in applications exceeding this thermal limit, whereas the SS22L M2G operates to 150°C.

Q: Are the packages physically identical?

A: Both parts use the DO-219AB package format, which is the surface mount equivalent of the Sub SMA / SMF package designation. Physical dimensions and PCB footprints are compatible, allowing direct board-level substitution without layout modification.

Q: What are the key electrical differences between these parts?

A: The primary difference is current rating: SS22L M2G is rated 2 A while SL02-GS08 is rated 1.1 A. Secondary differences include forward voltage (500 mV versus 420 mV at respective rated currents), reverse leakage current (400 µA versus 250 µA @ 20 V), and maximum junction temperature (150°C versus 125°C). Both maintain identical 20 V reverse voltage rating and fast recovery characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SS22L M2G and SL02-GS08 are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). Both maintain active product status with equivalent regulatory certifications.

Q: What is the reverse recovery time specification for the SS22L M2G?

A: The reverse recovery time (trr) is not specified in the SS22L M2G datasheet parameters. The part is classified as fast recovery with recovery time ≤ 500 ns for currents exceeding 200 mA. The SL02-GS08 substitute specifies a reverse recovery time of 10 ns.

Q: Can I use the SL02-GS08 in a 2 A application?

A: No. Operating the SL02-GS08 beyond its 1.1 A average rectified current rating will cause excessive junction heating, reduced component reliability, and potential thermal runaway. The SS22L M2G must be used for 2 A applications.
