Substitute Part Grouping Explanation

Substitute parts for the SS13-M3/5AT are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 30V reverse voltage rating, 1A average rectified current, 500mV forward voltage at 1A, fast recovery speed characteristics, and surface mount DO-214AC packaging. These parts are direct functional replacements with no performance trade-offs.

Manufacturer Recommended Alternatives provide equivalent electrical performance with variations in secondary parameters such as reverse leakage current, forward voltage characteristics, or operating temperature range. These parts satisfy the primary circuit requirements while offering different supplier options and availability profiles.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal 30V
Current - Average Rectified (Io): Must equal 1A
Package / Case: Must be DO-214AC, SMA
Mounting Type: Must be Surface Mount
Technology: Must be Schottky

Engineering Selection Recommendations

Vishay Parametric Equivalents (SS13-E3/5AT, SS13-E3/61T): These parts provide identical electrical and thermal specifications to the SS13-M3/5AT. Selection between these variants is determined by packaging reel configuration and inventory availability. All three Vishay parts maintain the same -65°C to 125°C operating temperature range and 200µA reverse leakage specification. These are direct substitutes with no performance differentiation.

Diodes Incorporated B130-13-F: This part matches the primary electrical specifications (30V, 1A) and extends the maximum operating temperature to 150°C. The reverse leakage current is specified at 500µA, which is higher than the SS13-M3/5AT. This part is suitable for applications requiring extended thermal performance.

Diodes Incorporated B130L-13-F: This part provides improved forward voltage characteristics (410mV versus 500mV at 1A), resulting in lower power dissipation. The reverse leakage current is specified at 1mA. The operating temperature range is -55°C to 125°C, which is narrower at the lower end compared to the SS13-M3/5AT. This part is suitable for applications prioritizing efficiency over extended low-temperature operation.

onsemi MBRA130LT3G: This part matches the B130L-13-F electrical and thermal specifications, offering an alternative source with identical forward voltage (410mV) and reverse leakage (1mA) characteristics. Operating temperature range is -55°C to 125°C.

Fairchild SS13: This part provides identical electrical specifications to the SS13-M3/5AT but is supplied in bulk packaging rather than tape and reel. This option is suitable for applications where reel packaging is not required.

All substitute parts listed are Active products with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can SS13-E3/5AT and SS13-E3/61T be used interchangeably with SS13-M3/5AT?

A: Yes. Both parts are Vishay parametric equivalents with identical electrical specifications (30V, 1A, 500mV forward voltage, 200µA reverse leakage) and operating temperature range (-65°C to 125°C). The difference between these variants is the reel configuration and tape specifications. Selection is based on packaging requirements and inventory availability.

Q: What is the difference between B130-13-F and B130L-13-F?

A: Both parts are manufactured by Diodes Incorporated and rated for 30V, 1A operation. The B130-13-F has a forward voltage of 500mV at 1A and reverse leakage of 500µA, with an operating temperature range of -65°C to 150°C. The B130L-13-F has a forward voltage of 410mV at 1A and reverse leakage of 1mA, with an operating temperature range of -55°C to 125°C. The B130L-13-F provides lower forward voltage drop, reducing power dissipation, but operates over a narrower temperature range.

Q: Is MBRA130LT3G electrically equivalent to B130L-13-F?

A: Yes. The onsemi MBRA130LT3G and Diodes Incorporated B130L-13-F share identical electrical specifications: 30V reverse voltage, 1A average rectified current, 410mV forward voltage at 1A, 1mA reverse leakage at 30V, and -55°C to 125°C operating temperature range. The primary difference is the manufacturer and packaging configuration.

Q: Can I use the Fairchild SS13 as a substitute?

A: Yes. The Fairchild SS13 provides identical electrical specifications to the SS13-M3/5AT (30V, 1A, 500mV forward voltage, 200µA reverse leakage, -65°C to 125°C operating range). The primary difference is the packaging format: the SS13 is supplied in bulk rather than tape and reel. This substitution is suitable for applications where reel packaging is not required.

Q: What are the key parameters that determine if a part can substitute for SS13-M3/5AT?

A: The critical parameters are: 30V maximum reverse voltage rating, 1A average rectified current, DO-214AC (SMA) surface mount package, fast recovery speed (≤500ns for >200mA), and Schottky technology. Forward voltage and reverse leakage current may vary between manufacturers while maintaining functional equivalence. Operating temperature range may differ based on specific application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the SS13-M3/5AT.

Q: What is the difference between tape and reel packaging and bulk packaging?

A: Tape and reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly equipment. Bulk packaging supplies loose components, typically used for manual assembly or lower-volume applications. The electrical specifications remain identical; the difference is in handling and assembly methodology.
