Substitute Part Grouping Explanation

Substitution of the SS13HR3G is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) Maximum: 30V
Current - Average Rectified (Io): 1A
Voltage - Forward (Vf) Maximum @ If: 500 mV @ 1 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Technology: Schottky
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount

Parametric Equivalent Parts maintain all primary equivalence criteria and are direct functional replacements:

SS13 (Fairchild Semiconductor)
SS13 R3G (Taiwan Semiconductor Corporation)
SS13H (Taiwan Semiconductor Corporation)

Similar Parts share the same voltage and current ratings with the same package family but may exhibit variations in secondary parameters such as reverse leakage current, forward voltage characteristics, or capacitance. These parts are suitable for substitution when application requirements permit tolerance of these variations.

Package Variants (B130LAW-7-F in SOD-123, B130B-13-F in SMB) provide equivalent electrical performance in alternative surface mount packages and are substitutable only when PCB layout and assembly equipment support the alternate package geometry.

Engineering Selection Recommendations

For Automotive Applications with AEC-Q101 Requirement:

SS13H (Taiwan Semiconductor Corporation) is the primary active substitute. This part maintains automotive-grade qualification (AEC-Q101) and identical electrical specifications to the SS13HR3G, including the same operating temperature range (-55°C to 125°C), reverse voltage rating (30V), forward current (1A), and forward voltage characteristic (500 mV @ 1A). The part is currently active in production and available in Tape & Reel packaging.

B130Q-13-F (Diodes Incorporated) provides an alternative automotive-qualified option with AEC-Q101 certification. This part shares identical primary electrical parameters but extends the operating temperature range to -65°C to 150°C and offers higher inventory availability. The reverse leakage current is specified at 500 µA @ 30V compared to 200 µA for the original part, which remains within acceptable limits for most rectification applications.

For Non-Automotive Applications:

B130L-13-F (Diodes Incorporated) offers superior performance characteristics with lower forward voltage (410 mV @ 1A versus 500 mV), extended temperature range (-55°C to 125°C), and high inventory availability (210,200 units). The increased reverse leakage current (1 mA @ 30V) is acceptable for applications not requiring the original specification.

B130-13-F (Diodes Incorporated) provides active-status availability with standard specifications matching the original part's electrical performance (500 mV @ 1A forward voltage, 500 µA reverse leakage) and extended temperature range (-65°C to 150°C).

For Package-Constrained Designs:

B130LAW-7-F (Diodes Incorporated) in SOD-123 package provides equivalent electrical performance for designs requiring smaller form factor. This part is suitable only when PCB layout and assembly processes support SOD-123 package geometry.

B130B-13-F (Diodes Incorporated) in SMB package provides equivalent electrical performance for designs requiring larger thermal dissipation capability or specific PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can SS13H be used as a direct replacement for SS13HR3G?

A: Yes. SS13H maintains identical electrical specifications (30V reverse voltage, 1A forward current, 500 mV forward voltage @ 1A, 200 µA reverse leakage @ 30V), the same DO-214AC (SMA) package, automotive-grade qualification (AEC-Q101), and identical operating temperature range (-55°C to 125°C). The part is currently in active production status.

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

A: Both parts share the same 30V reverse voltage, 1A forward current rating, and DO-214AC (SMA) package. B130-13-F specifies 500 mV forward voltage @ 1A and 500 µA reverse leakage @ 30V. B130L-13-F specifies 410 mV forward voltage @ 1A and 1 mA reverse leakage @ 30V. B130L-13-F offers lower forward voltage drop, beneficial for efficiency-sensitive applications, while B130-13-F maintains the original forward voltage specification. Both are suitable substitutes depending on application requirements.

Q: Is B130Q-13-F suitable for automotive applications?

It maintains the same 30V reverse voltage, 1A forward current, and 500 mV forward voltage @ 1A as the original SS13HR3G. This part is suitable for automotive applications requiring AEC-Q101 certification.

Q: Can I use B130LAW-7-F as a substitute if my PCB supports SOD-123 package?

A: Yes, if your PCB layout and assembly equipment support SOD-123 package geometry. B130LAW-7-F maintains the same 30V reverse voltage and 1A forward current ratings. The forward voltage is specified at 420 mV @ 1A (compared to 500 mV for the original), and reverse leakage is 1 mA @ 30V. Verify that your assembly process and thermal management design accommodate the SOD-123 package before implementation.

Q: What is the inventory status of available substitutes?

A: SS13H (Taiwan Semiconductor) has 760 units in stock. B130L-13-F (Diodes Incorporated) has the highest availability at 210,200 units. B130-13-F has 155,100 units. B130Q-13-F has 10,200 units. B130B-13-F has 19,800 units. B130LAW-7-F has 125,100 units. Fairchild Semiconductor SS13 has 20,050 units available.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, consistent with the original SS13HR3G specification.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: All substitute parts listed carry MSL 1 (Unlimited) rating, matching the original SS13HR3G specification.
