Product details
Overview
B230A-13 from Diodes Incorporated is a 30 V, 2.0 A surface-mount Schottky barrier rectifier in SMA package, featuring 0.50 V forward voltage at 2.0 A, 50 A non-repetitive surge rating, and AEC-Q101 qualification for automotive use. It serves as a low-loss freewheeling or polarity protection diode in DC/DC converters and 12 V automotive power rails.
For engineers reviewing the B230A-13 datasheet, B230A-13 pinout, B230A-13 application, or B230A-13 equivalent, key selection criteria include its 30 V reverse voltage rating, thermal resistance of 25 °C/W (junction-to-lead), RoHS-compliant matte tin plating, and suitability for high-frequency switching up to 1 MHz with 200 pF capacitance.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress leakage under reverse bias. Its low VF enables high efficiency in low-voltage (<5 V) output stages, while the 50 A IFSM rating supports inrush current handling in power supply inputs.
The device operates across –65 °C to +150 °C and maintains <0.5 mA IR at 30 V and 25 °C, enabling stable performance in thermally demanding engine bay environments. Its 200 pF CT at 40 V supports fast switching in SMPS flyback and buck topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/52 (Vishay) | Same 30 V VRRM, 2.0 A IO, but SMB package (RθJL = 20 °C/W); VF = 0.52 V @ 2 A | SMB offers higher thermal dissipation but requires larger pad layout; less suitable for ultra-thin automotive modules | Select when board-level thermal management prioritizes junction-to-ambient over footprint size |
| SS23 (ON Semiconductor) | 30 V VRRM, 2.0 A IO, SMA package, but VF = 0.55 V @ 2 A and IR = 1.0 mA @ 30 V | Higher leakage limits use in battery-backed systems; same footprint enables drop-in replacement with minor efficiency trade-off | Select when cost sensitivity outweighs 50 mW conduction loss increase per diode |
Compared with SB230-E3/52 and SS23, B230A-13 delivers the lowest VF (0.50 V) in SMA form factor and AEC-Q101 qualification-critical for space-constrained automotive modules requiring both reliability and efficiency.

FAQ
What is the maximum junction temperature for B230A-13 during continuous operation?
The B230A-13 has an operating junction temperature range of –65 °C to +150 °C. Under 2.0 A DC load with adequate PCB copper (≥1 cm² 2 oz Cu), junction temperature remains below 125 °C at +85 °C ambient due to its 25 °C/W RθJL and low 0.50 V VF. Derating begins above +100 °C ambient per Figure 4 in DS13004.
Is B230A-13 compatible with lead-free reflow profiles?
Yes. B230A-13 features matte tin lead-free plating and is qualified for high-temperature soldering at +260 °C for 10 seconds per MIL-STD-202, Method 208. Its moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to reflow.
How does the guard ring construction improve reliability?
The guard ring die structure suppresses edge leakage and prevents premature avalanche breakdown under transient overvoltage. This design directly enables the 50 A IFSM rating and AEC-Q101 qualification, making it resistant to load dump spikes and ESD events common in automotive 12 V systems.
Can B230A-13 replace B230-13 in existing designs?
Yes-B230A-13 and B230-13 share identical electrical specs and SMA packaging, but B230A-13 adds AEC-Q101 qualification and automotive-grade traceability. No layout or firmware changes are needed; it is a direct upgrade for automotive or high-reliability industrial use.
