Current - Average Rectified (Io): 1A
Technology: Schottky
Mounting Type: Surface Mount
Package / Case: DO-214AC, SMA (or functionally equivalent packages)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Considerations:

Voltage - Forward (Vf) Maximum @ If: Acceptable range 395 mV to 550 mV @ 1A

Engineering Selection Recommendations

Primary Recommendation for New Designs:

B130-13-F (Diodes Incorporated) is the direct parametric equivalent with identical electrical specifications to the original B130-13. This part is manufactured by the same supplier, maintains full compatibility with existing PCB layouts, and carries ROHS3 compliance certification. Product status is Active with substantial inventory availability (155,100 pieces).

B130Q-13-F (Diodes Incorporated) provides an automotive-qualified alternative with AEC-Q101 certification and Tape & Reel packaging. Electrical specifications are identical to B130-13-F. This variant is suitable for applications requiring automotive-grade reliability.

Secondary Recommendations for Active Production:

STPS1L30A (STMicroelectronics) offers the lowest forward voltage drop (395 mV @ 1A) among available substitutes, reducing power dissipation in rectification circuits. ROHS3 compliant, Active status, and DO-214AC package compatibility. Reverse leakage current is 200 µA @ 30V.

STPS130A (STMicroelectronics) provides the lowest reverse leakage current (10 µA @ 30V) among available substitutes, beneficial for low-power standby applications. ROHS3 compliant, Active status, and DO-214AC package compatibility. Forward voltage is 550 mV @ 1A.

MBRA130LT3G (onsemi) maintains full electrical equivalence with 30V/1A ratings and DO-214AC package. ROHS3 compliant and Active status. Forward voltage is 410 mV @ 1A with higher reverse leakage (1 mA @ 30V).

Legacy Application Support:

RBR1L30ATE25 (Rohm Semiconductor) is marked Not For New Designs but remains available for legacy system maintenance. Electrical specifications are within acceptable tolerance ranges. ROHS3 compliant.

SS13-LTP (Micro Commercial Co) is marked Not For New Designs but maintains full parametric equivalence to the original B130-13. ROHS3 compliant. Suitable for repair and field replacement of existing assemblies.

SS13 (Fairchild Semiconductor) is Active status with DO-214AC package compatibility. RoHS compliance status not specified in available data.

Package Variant:

PMEG3010BEP,115 (Nexperia USA Inc.) uses SOD-128 package instead of DO-214AC/SMA. Electrical specifications are equivalent (30V/1A, 450 mV forward voltage). This variant requires PCB layout modification and is suitable only when package footprint change is acceptable.

Frequently Asked Questions (FAQ)

Q: Can B130-13-F be used as a direct replacement for B130-13 without PCB modification?

A: Yes. B130-13-F is a parametric equivalent with identical electrical specifications and DO-214AC/SMA package. No PCB layout changes are required. The primary difference is ROHS3 compliance and Active product status.

Q: What is the difference between B130-13-F and B130Q-13-F?

A: Both parts are parametric equivalents with identical electrical specifications. B130Q-13-F carries AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging. B130-13-F is supplied in Cut Tape & Digi-Reel packaging. Selection depends on packaging requirements and automotive qualification necessity.

Q: Which substitute offers the best performance for low-power applications?

A: STPS130A provides the lowest reverse leakage current (10 µA @ 30V), making it optimal for applications where standby power consumption is critical. STPS1L30A offers the lowest forward voltage drop (395 mV @ 1A), reducing power dissipation during conduction.

Q: Can PMEG3010BEP,115 be used as a substitute?

A: PMEG3010BEP,115 meets all electrical specifications (30V/1A, fast recovery Schottky) but uses SOD-128 package instead of DO-214AC/SMA. This requires PCB footprint redesign and is not a direct drop-in replacement. Use only when package change is acceptable.

Q: Are all recommended substitutes RoHS compliant?

A: All recommended substitutes except SS13 (Fairchild Semiconductor) carry explicit ROHS3 compliance certification. For new designs, ROHS3-compliant parts are required. SS13 is suitable only for legacy applications where RoHS compliance is not mandated.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" (RBR1L30ATE25, SS13-LTP) are in mature or end-of-life phases. These parts remain available for existing product maintenance and field replacement but should not be selected for new circuit designs. Prefer Active status parts for new applications.

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage (Vf) ranges from 395 mV to 550 mV across available substitutes. In rectification circuits, lower Vf reduces power dissipation and heat generation. In voltage-sensitive applications, verify that the selected part's Vf does not exceed circuit design margins. STPS1L30A (395 mV) and MBRA130LT3G (410 mV) minimize dissipation; STPS130A (550 mV) maximizes voltage drop.

Q: What is the impact of reverse leakage current variation?

A: Reverse leakage current ranges from 10 µA to 1 mA @ 30V across available substitutes. Lower leakage reduces standby power consumption and improves circuit efficiency in low-power applications. Higher leakage is acceptable in high-current rectification circuits where leakage current is negligible relative to forward current.

Q: Can substitutes with different operating temperature ranges be used?

A: The original B130-13 operates from -65°C to 150°C. Most substitutes operate from -55°C to 150°C, reducing the low-temperature range by 10°C. Verify that the application's minimum operating temperature does not fall below the substitute part's specified range. For applications requiring -65°C operation, B130-13-F or B130Q-13-F are required.

Q: Is inventory availability a factor in part selection?

A: Yes. B130-13-F has the highest inventory (155,100 pieces), followed by STPS1L30A (17,164 pieces) and STPS130A (19,400 pieces). For high-volume production, parts with substantial inventory reduce supply chain risk. PMEG3010BEP,115 has limited inventory (1,127 pieces) and should be evaluated for long-term availability.
