Engineering Selection Recommendations

Direct Equivalents (Same Package, Same Current Rating):

B130Q-13-F (Diodes Incorporated) is the primary substitute for SSL13H. Both parts are AEC-Q101 qualified, rated for 30V/1A in DO-214AC (SMA) package, and maintain identical operating temperature range. Forward voltage specification is higher (500 mV vs. 390 mV @ 1A), and reverse leakage is higher (500 µA vs. 200 µA @ 30V), but both remain within acceptable Schottky diode performance parameters.

B130-E3/5AT and B130-E3/61T (Vishay General Semiconductor - Diodes Division) provide equivalent electrical performance in DO-214AC (SMA) package with 30V/1A ratings. These parts are not AEC-Q101 qualified but maintain RoHS3 compliance. Forward voltage is 520 mV @ 1A and reverse leakage is 200 µA @ 30V, matching the SSL13H leakage specification.

B130L-13-F (Diodes Incorporated) offers superior forward voltage performance (410 mV @ 1A) in DO-214AC (SMA) package with identical temperature range (-55°C ~ 125°C). Reverse leakage is higher at 1 mA @ 30V.

Alternative Package Options (Same Current Rating):

B130LAW-7-F (Diodes Incorporated) provides 30V/1A Schottky performance in SOD-123 package. This substitution requires PCB layout modification due to different footprint. Forward voltage is 420 mV @ 1A with 1 mA reverse leakage @ 30V.

B130B-13-F (Diodes Incorporated) provides 30V/1A Schottky performance in DO-214AA (SMB) package. This substitution requires PCB layout modification. Forward voltage is 500 mV @ 1A with 500 µA reverse leakage @ 30V.

Higher Current Ratings (Electrical Superset):

B130LB-13-F (Diodes Incorporated) and B230AQ-13-F (Diodes Incorporated) are rated for 30V/2A, exceeding the SSL13H 1A specification. B230AQ-13-F is AEC-Q101 qualified. Both maintain DO-214AC (SMA) package compatibility. These parts are suitable for applications requiring additional current margin.

B230LA-E3/5AT (Vishay General Semiconductor - Diodes Division) provides 30V/2A performance in DO-214AC (SMA) package without AEC-Q101 qualification.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. AEC-Q101 qualification is preserved in B130Q-13-F and B230AQ-13-F. Applications requiring automotive qualification should prioritize these qualified alternatives.

Frequently Asked Questions (FAQ)

Q: Can B130Q-13-F directly replace SSL13H without PCB modification?

A: Yes. B130Q-13-F maintains identical DO-214AC (SMA) package footprint and pinout as SSL13H. No PCB layout changes are required. Both parts are AEC-Q101 qualified and RoHS3 compliant.

Q: What is the difference between B130-E3/5AT and B130-E3/61T?

A: Both parts are electrically identical 30V/1A Schottky diodes in DO-214AC (SMA) package from Vishay. The difference is packaging format: B130-E3/5AT is supplied in Tape & Reel (TR), while B130-E3/61T is supplied in Cut Tape (CT). Electrical specifications and performance are equivalent.

Q: Why does B130-13-F have higher forward voltage (500 mV) than SSL13H (390 mV)?

A: Forward voltage variation is inherent to Schottky diode manufacturing and is within normal specification ranges. The 110 mV difference reflects different process parameters and design optimization between Taiwan Semiconductor Corporation and Diodes Incorporated. Both values are acceptable for typical rectification applications.

Q: Can I use B130LAW-7-F (SOD-123 package) as a substitute?

A: B130LAW-7-F is electrically equivalent but uses SOD-123 package instead of DO-214AC (SMA). This substitution requires PCB layout redesign to accommodate the different footprint. Use only if board redesign is feasible.

Q: Is B230AQ-13-F suitable for a 1A application?

A: Yes. B230AQ-13-F is rated for 30V/2A, which exceeds the 1A requirement. The part is AEC-Q101 qualified and maintains DO-214AC (SMA) package compatibility. It provides additional current margin and is suitable for 1A applications.

Q: What is the temperature range difference between SSL13H and B130Q-13-F?

A: SSL13H operates from -55°C to 125°C. B130Q-13-F operates from -65°C to 150°C. B130Q-13-F provides extended low-temperature performance (-10°C additional) and extended high-temperature performance (+25°C additional), making it suitable for wider environmental conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching SSL13H environmental compliance.

Q: Which substitute offers the lowest forward voltage drop?

A: B130L-13-F provides the lowest forward voltage at 410 mV @ 1A, compared to SSL13H at 390 mV @ 1A. B130LAW-7-F offers 420 mV @ 1A. For applications sensitive to forward voltage drop, B130L-13-F is the optimal choice among 1A-rated alternatives.

Q: Can I substitute SSL13H with a higher current part like B130LB-13-F in a 1A circuit?

A: Yes. B130LB-13-F is rated for 30V/2A and is electrically suitable for 1A applications. The higher current rating provides design margin. However, verify that thermal management and circuit layout accommodate the different package (SMB vs. SMA).
