Key Parameters

Substitute Part Grouping Explanation

Substitution of the B230AE-13 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 2 A
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: 500–550 mV @ 2 A
• Current - Reverse Leakage @ Vr: 100–500 µA @ 30 V
• Capacitance @ Vr, F: 93–200 pF @ 4V, 1MHz
• Operating Temperature - Junction: -65°C to -55°C minimum; 150°C maximum

All identified substitute parts meet or exceed the mandatory parameter requirements and fall within acceptable variation ranges for reverse leakage and capacitance characteristics.

Parameter Comparison

Engineering Selection Recommendations

B230A-13-F (Diodes Incorporated): Direct manufacturer substitute with active product status. Maintains identical voltage and current ratings with matching forward voltage specification. Extended operating temperature range (-65°C minimum) provides additional thermal margin. MSL rating of 1 (Unlimited) eliminates moisture sensitivity constraints. ROHS3 and REACH compliance maintained. Recommended as primary substitute for direct replacement applications.

SK23A (Good-Ark Semiconductor): Parametric equivalent with active product status and AEC-Q101 automotive qualification. Meets all mandatory electrical parameters with forward voltage of 550 mV at 2A, within acceptable variation. MSL rating of 1 (Unlimited) and ROHS3 compliance confirmed. Automotive-grade qualification suitable for applications requiring automotive-level reliability.

SK23AH (Taiwan Semiconductor Corporation): Parametric equivalent with active product status and AEC-Q101 automotive qualification. Matches forward voltage specification at 500 mV @ 2A. MSL rating of 1 (Unlimited) and ROHS3 compliance confirmed. Automotive-grade qualification suitable for applications requiring automotive-level reliability. Capacitance specification not provided in available data.

All three substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can B230A-13-F be used as a direct replacement for B230AE-13?

A: Yes. B230A-13-F is a direct manufacturer substitute from Diodes Incorporated with identical electrical specifications (30V, 2A, 500 mV forward voltage @ 2A) and package configuration (DO-214AC, SMA). The primary difference is active product status and extended temperature range (-65°C to 150°C versus -55°C to 150°C).

Q: What is the difference between B230A-13-F and the SK23A/SK23AH alternatives?

A: B230A-13-F is a direct manufacturer equivalent from Diodes Incorporated. SK23A and SK23AH are parametric equivalents from alternative manufacturers (Good-Ark Semiconductor and Taiwan Semiconductor Corporation, respectively) with identical voltage and current ratings. SK23A and SK23AH carry AEC-Q101 automotive qualification, while B230A-13-F does not specify automotive grade.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical and thermal compatibility with the original B230AE-13 footprint.

Q: What is the significance of the forward voltage difference in SK23A (550 mV vs. 500 mV)?

A: The SK23A forward voltage specification of 550 mV @ 2A is within acceptable variation for Schottky diode applications. This 50 mV difference represents approximately 10% variation and falls within typical manufacturing tolerances for this device category. Circuit designs must account for this specification in power dissipation calculations.

Q: Do all substitute parts have the same reverse leakage current?

A: No. The B230AE-13 specifies 100 µA @ 30V reverse leakage, while B230A-13-F, SK23A, and SK23AH all specify 500 µA @ 30V. This five-fold increase in leakage current is within acceptable variation for Schottky rectifiers and does not affect functional compatibility in standard rectification applications.

Q: What does MSL 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component has no moisture sensitivity constraints. These parts can be stored and handled without special moisture control measures, simplifying logistics and inventory management compared to higher MSL ratings.

Q: Are SK23A and SK23AH suitable for automotive applications?

A: Yes. Both SK23A and SK23AH carry AEC-Q101 automotive qualification, indicating compliance with automotive industry reliability and quality standards. These parts are suitable for automotive-grade applications requiring formal qualification documentation.
