Engineering Selection Recommendations

Tier 1 - Direct Replacement (Identical Specifications):

B230A-13-F is the primary direct equivalent from Diodes Incorporated. This part maintains all electrical specifications of the original B230A-13 while offering ROHS3 compliance and active product status. The packaging is identical (DO-214AC, SMA), and the part is available in Cut Tape and Digi-Reel formats.

B230AQ-13-F provides an automotive-qualified alternative (AEC-Q101) with identical electrical specifications. This part is suitable for applications requiring automotive-grade components and is available in Tape & Reel packaging.

Tier 2 - Parametric Equivalents (Same Electrical Performance, Different Package):

PMEG3020BEP,115 from Nexperia USA Inc. meets the 30V/2A specification with improved forward voltage (450 mV @ 2A) and lower reverse leakage (100 µA @ 30V). The package differs (SOD-128 instead of SMA), requiring PCB layout modification. This part is suitable for applications where package size is not a constraint.

Tier 3 - Cross-Manufacturer Substitutes (2A Rating, SMA Package):

SSA23L-E3/5AT and SSA23L-E3/61T from Vishay General Semiconductor provide 30V/2A performance in DO-214AC (SMA) packaging with forward voltage of 450 mV @ 2A. Both parts are active and ROHS3 compliant. These parts are direct pin-compatible replacements.

SSA23L-M3/5AT from Vishay offers 30V/2A performance with forward voltage of 490 mV @ 2A, providing a middle ground between the original specification and lower-Vf alternatives.

Tier 4 - Current-Limited Alternatives (1A Rating, SMA Package):

STPS130A and STPS1L30A from STMicroelectronics are rated for 1A average rectified current. These parts are suitable only for applications where the circuit design permits operation at reduced current levels. STPS1L30A offers superior forward voltage performance (395 mV @ 1A).

Not Recommended for New Designs:

SS23-LTP from Micro Commercial Co carries a "Not For New Designs" status and should be avoided for new product development, though it remains available for legacy system support.

Frequently Asked Questions (FAQ)

Q: Can B230A-13-F be used as a direct replacement for B230A-13?

A: Yes. B230A-13-F is a direct equivalent with identical electrical specifications (30V, 2A, 500 mV @ 2A forward voltage) and the same SMA package. The primary difference is active product status and ROHS3 compliance. No circuit modifications are required.

Q: What is the difference between B230A-13-F and B230AQ-13-F?

A: Both parts have identical electrical specifications. B230AQ-13-F includes automotive qualification (AEC-Q101) and is supplied in Tape & Reel packaging, while B230A-13-F is available in Cut Tape and Digi-Reel formats. Selection depends on packaging requirements and automotive compliance needs.

Q: Can PMEG3020BEP,115 replace B230A-13 in all applications?

A: PMEG3020BEP,115 meets the 30V/2A electrical requirements with improved performance (450 mV forward voltage vs. 500 mV). However, the package differs (SOD-128 vs. SMA), requiring PCB layout changes. Electrical compatibility is confirmed; mechanical compatibility requires design review.

Q: Why are STPS130A and STPS1L30A listed as substitutes if they are rated for only 1A?

A: These parts are included for applications where circuit design permits operation at reduced current levels. They maintain the 30V reverse voltage rating and SMA package compatibility. Use is restricted to circuits where 1A average rectified current is sufficient.

Q: What does "Not For New Designs" mean for SS23-LTP?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. SS23-LTP remains available for legacy system support and repair but should not be selected for new applications.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. The original B230A-13 is RoHS non-compliant. If RoHS compliance is a requirement, B230A-13-F or any other listed substitute must be used.

Q: What is the impact of forward voltage differences between substitutes?

A: Forward voltage variations (395 mV to 550 mV @ rated current) affect power dissipation and thermal performance. Lower forward voltage reduces heat generation. Circuit designs with tight thermal budgets should prioritize lower-Vf alternatives such as PMEG3020BEP,115 (450 mV) or STPS1L30A (395 mV @ 1A).

Q: Can parts with different reverse leakage specifications be used interchangeably?

A: Yes, within the specified operating range. Reverse leakage varies from 100 µA to 500 µA @ 30V across the substitute list. Higher leakage increases standby current consumption. Applications sensitive to leakage current should select PMEG3020BEP,115 (100 µA) or STPS1L30A (200 µA).

Q: Is package compatibility critical for substitution?

A: Yes. Parts with identical SMA (DO-214AC) packages are direct mechanical replacements. PMEG3020BEP,115 uses SOD-128 packaging and requires PCB layout modification. SS23S-E3/61T uses DO-214AA (SMB) packaging, which is larger and not pin-compatible with SMA footprints.
