Packaging Format: SS23HE3_A/I is supplied in Tape & Reel (TR); B230-13-F is supplied in Cut Tape (CT) & Digi-Reel®
Reverse Leakage: B230-13-F exhibits 500 µA leakage versus 400 µA for SS23HE3_A/I, both within acceptable limits for 30V Schottky rectifier applications
Compliance Certifications: Both devices maintain equivalent regulatory status (RoHS3, REACH Unaffected, EAR99)

Frequently Asked Questions (FAQ)

Q: Can B230-13-F be used as a direct replacement for SS23HE3_A/I in existing designs?

A: Yes. Both devices meet identical electrical specifications for reverse voltage (30V), forward current (2A), forward voltage drop (500 mV @ 2A), and recovery speed (≤ 500ns). The DO-214AA (SMB) package footprint is identical, enabling direct PCB substitution.

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

A: The SS23HE3_A/I specifies 400 µA maximum 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 rectifiers and does not affect circuit performance in standard rectification applications.

Q: Are there packaging differences between these parts?

A: Both devices use the DO-214AA (SMB) surface mount package. The primary difference is the supply format: SS23HE3_A/I is supplied in Tape & Reel (TR), while B230-13-F is supplied in Cut Tape (CT) & Digi-Reel®. The component itself and PCB footprint are identical.

Q: Do both parts meet automotive qualification requirements?

A: The SS23HE3_A/I carries AEC-Q101 automotive qualification. The B230-13-F specification provided does not explicitly list AEC-Q101 qualification. For applications requiring automotive-grade certification, the SS23HE3_A/I is the specified choice.

Q: What is the operating temperature range for both devices?

A: Both the SS23HE3_A/I and B230-13-F operate across a junction temperature range of -65°C to 150°C, supporting industrial and automotive temperature environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SS23HE3_A/I and B230-13-F are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, supporting unrestricted use in lead-free manufacturing processes.
