Substitute Part Grouping Explanation

Substitute parts for the SS23HE3_A/H are identified through direct parametric equivalence. The substitution criteria are based on the following electrical and mechanical parameters that must match or remain within acceptable tolerances:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) Maximum: 30V
Current - Average Rectified (Io): 2A
Voltage - Forward (Vf) Maximum @ If: 500 mV @ 2A
Speed Classification: Fast Recovery ≤ 500ns at >200mA
Package / Case: DO-214AA (SMB)
Technology: Schottky
Mounting Type: Surface Mount
Operating Temperature Range: -65°C to 150°C

The B230-13-F from Diodes Incorporated satisfies all critical electrical parameters and mechanical compatibility requirements. Both parts are Schottky technology devices with identical voltage and current ratings, forward voltage characteristics, and fast recovery speed specifications. Both operate across the same temperature range and utilize the same surface mount SMB package footprint.

Engineering Selection Recommendations

Both the SS23HE3_A/H and B230-13-F are active product status components with full regulatory compliance. The SS23HE3_A/H carries AEC-Q101 automotive qualification, which is a specific requirement for automotive-grade applications. The B230-13-F does not list AEC-Q101 qualification in the provided specifications.

For automotive applications requiring AEC-Q101 qualification: The SS23HE3_A/H is the specified component and should be used.

For general industrial and commercial applications: The B230-13-F provides parametric equivalence with identical electrical performance and mechanical compatibility. Both parts are RoHS3 compliant, REACH unaffected, and operate across the full -65°C to 150°C junction temperature range.

The reverse leakage current specification for B230-13-F (500 µA @ 30V) is slightly higher than the SS23HE3_A/H (400 µA @ 30V), remaining within acceptable tolerance for Schottky diode applications at this voltage and current rating.

Frequently Asked Questions (FAQ)

Q: Can the B230-13-F be used as a direct replacement for the SS23HE3_A/H in all applications?

A: The B230-13-F is electrically and mechanically equivalent for non-automotive applications. For automotive applications requiring AEC-Q101 qualification, the SS23HE3_A/H must be used as specified.

Q: Are the packages physically identical?

A: Both parts use the DO-214AA (SMB) surface mount package. The footprint and land pattern are identical, allowing direct PCB substitution without layout modifications.

Q: What is the difference in reverse leakage current between these parts?

A: The SS23HE3_A/H specifies 400 µA maximum reverse leakage at 30V, while the B230-13-F specifies 500 µA maximum at 30V. This 100 µA difference is within normal manufacturing tolerance for Schottky diodes and does not affect circuit performance in standard rectification applications.

Q: Do both parts have the same forward voltage drop?

A: Yes. Both parts specify 500 mV maximum forward voltage at 2A forward current, ensuring identical voltage drop characteristics in circuit operation.

Q: Are there any temperature range differences?

A: No. Both parts operate across the identical junction temperature range of -65°C to 150°C.

Q: What is the packaging difference between these parts?

A: The SS23HE3_A/H is supplied in Tape & Reel (TR) packaging, while the B230-13-F is supplied in Cut Tape (CT) and Digi-Reel® packaging. Both are surface mount formats suitable for automated assembly.

Q: Can these parts be mixed in the same production run?

A: For non-automotive applications, yes. For automotive applications with AEC-Q101 requirements, parts must not be mixed; only the SS23HE3_A/H should be used.
