SS13 Schottky Diode 30V 1A DO-214AC Equivalent & Substitute Parts

Part Overview

The SS13 is a Schottky rectifier diode manufactured by onsemi, rated for 30V reverse voltage and 1A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Equivalent and substitute parts are necessary to support existing designs, provide design flexibility, and ensure supply chain continuity for applications requiring 30V/1A Schottky rectification in surface mount form factor.

Substitute Part Grouping Explanation

Substitution of the SS13 is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 30V
Current - Average Rectified (Io): 1A minimum
Package / Case: DO-214AC (SMA) or compatible surface mount package
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

Voltage - Forward (Vf) (Max) @ If: Substitute parts may have lower forward voltage (improved performance)
Current - Reverse Leakage @ Vr: Substitute parts may have higher leakage (acceptable within design margins)
Operating Temperature - Junction: Substitute parts may have extended temperature range (acceptable)

Non-Substitutable Parameters:

Parts with current ratings below 1A
Parts with reverse voltage below 30V
Parts with non-SMA surface mount packages (except where package is functionally equivalent)

Substitute parts are grouped into two categories: Direct Equivalents (identical electrical and thermal specifications) and Functional Equivalents (meet or exceed all critical parameters with acceptable variations).

Engineering Selection Recommendations

Direct Equivalent (Recommended for Pin-Compatible Replacement):

SS13-E3/5AT (Vishay General Semiconductor - Diodes Division) is the primary direct equivalent. It maintains identical electrical specifications (30V, 1A, 500mV forward voltage, 200µA reverse leakage) and thermal range (-65°C to 125°C) as the SS13. This part is in Active product status and provides the most straightforward replacement path with no design modifications required.

Functional Equivalents (1A Current Rating, 30V Voltage Rating):

The following parts meet or exceed all critical electrical parameters while maintaining the 1A/30V rating and DO-214AC (SMA) package:

MBRA130LT3G (onsemi): Lower forward voltage (410mV), higher reverse leakage (1mA), Active status
STPS1L30A (STMicroelectronics): Lower forward voltage (395mV), extended temperature range to 150°C, Active status
B130-13-F (Diodes Incorporated): Identical forward voltage (500mV), higher reverse leakage (500µA), extended temperature range to 150°C, Active status
B130L-13-F (Diodes Incorporated): Lower forward voltage (410mV), higher reverse leakage (1mA), Active status
B130Q-13-F (Diodes Incorporated): Identical forward voltage (500mV), AEC-Q101 automotive qualification, extended temperature range to 150°C, Active status

Higher Current Rating Alternatives (Backward Compatible):

B230A-13-F, B230AQ-13-F, and B330A-13-F provide 2A and 3A current ratings respectively, maintaining 30V reverse voltage and DO-214AC (SMA) package. These are suitable for applications requiring higher current capacity while maintaining voltage and package compatibility. B230AQ-13-F and B330A-13-F include AEC-Q101 automotive qualification.

Package Variant (SOD-128):

PMEG3010BEP,115 (Nexperia USA Inc.) provides equivalent electrical performance (30V, 1A, 450mV forward voltage) but uses SOD-128 package instead of DO-214AC (SMA). This part is suitable only for designs that can accommodate the different package footprint.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original SS13 specifications.

Frequently Asked Questions (FAQ)

Q: Can I use B230A-13-F (2A rating) as a direct replacement for SS13 (1A rating)?

A: Yes. B230A-13-F is electrically and mechanically compatible with SS13. The higher current rating (2A vs. 1A) does not prevent its use in 1A applications. The part maintains the same 30V reverse voltage, DO-214AC (SMA) package, and fast recovery Schottky technology. Forward voltage and reverse leakage characteristics are identical to the original SS13.

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

A: Both parts are 30V/1A Schottky diodes in DO-214AC (SMA) package from Diodes Incorporated. B130-13-F has 500mV forward voltage and 500µA reverse leakage. B130L-13-F has lower forward voltage (410mV) and higher reverse leakage (1mA). The "L" designation indicates the low forward voltage variant. Selection depends on whether lower forward voltage drop or lower reverse leakage is prioritized in the application.

Q: Is PMEG3010BEP,115 a suitable replacement for SS13?

A: PMEG3010BEP,115 meets all electrical specifications (30V, 1A, fast recovery Schottky) but uses SOD-128 package instead of DO-214AC (SMA). It is electrically compatible but requires PCB layout modification due to different package footprint. Use this part only if the application design can accommodate SOD-128 package dimensions.

Q: Why do some substitute parts have higher reverse leakage current than SS13?

A: Reverse leakage current variation is a normal characteristic of Schottky diode manufacturing. Parts with higher reverse leakage (e.g., 1mA vs. 200µA) remain functionally equivalent provided the application design accounts for this leakage in power budget calculations. Higher reverse leakage does not affect switching performance or forward conduction characteristics.

Q: Can I use STPS1L30A if my application requires operation above 125°C?

A: Yes. STPS1L30A has a maximum junction temperature of 150°C, compared to SS13's 125°C. If your application requires operation in the 125°C to 150°C range, STPS1L30A provides extended thermal capability while maintaining all other electrical specifications identical to SS13.

Q: What does AEC-Q101 qualification mean for B130Q-13-F and B230AQ-13-F?

A: AEC-Q101 is an automotive industry qualification standard. Parts carrying this qualification have undergone additional reliability testing and are approved for automotive applications. If your design requires automotive-grade components, B130Q-13-F (1A) or B230AQ-13-F (2A) are suitable selections. Non-automotive applications can use either qualified or non-qualified variants interchangeably.

Q: Are all substitute parts available in the same packaging format (Tape & Reel)?

A: No. SS13 is supplied in Tape & Reel (TR) packaging. SS13-E3/5AT is also available in TR. Most other substitutes are available in Cut Tape (CT) & Digi-Reel® format. Verify packaging availability with your supplier if TR format is required for automated assembly processes.

Q: What is the primary advantage of STPS1L30A over SS13?

A: STPS1L30A offers lower forward voltage (395mV vs. 500mV at 1A), resulting in reduced power dissipation and improved efficiency. It also provides extended maximum junction temperature (150°C vs. 125°C). These characteristics make STPS1L30A suitable for applications prioritizing thermal performance and power efficiency.
