Product details
Overview
B230A-13-F 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 diode in DC-DC converters and polarity protection switch in 12 V automotive power rails.
For engineers reviewing the B230A-13-F datasheet, B230A-13-F pinout, B230A-13-F application, or B230A-13-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (25 °C/W junction-to-lead), peak reverse voltage margin, and RoHS/Green compliance status for high-reliability PCB assembly.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche breakdown and supports automated SMT placement with lead-free matte tin plating solderable per MIL-STD-202. Its low VF enables high-efficiency operation in low-voltage (<30 V) switching topologies.
Thermal performance is defined by RθJL = 25 °C/W (SMA), enabling 2.0 A continuous conduction at ≤100 °C terminal temperature. Reverse leakage remains ≤0.5 mA at 30 V and 25 °C, critical for standby power integrity in always-on vehicle modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; sets safe operating limit in 12 V automotive systems with load dump transients. |
| IF(AV) | 2.0 A - Average forward current rating at TA = 25 °C; derates to ~1.2 A at 100 °C ambient per Fig. 4. |
| VF | 0.50 V @ 2.0 A - Low conduction loss; reduces power dissipation to ≤1.0 W at full load, easing thermal design. |
| IFSM | 50 A - Non-repetitive surge rating for 8.3 ms half-sine; withstands motor commutation spikes and inductive kickback. |
| IR | ≤0.5 mA @ 30 V, 25 °C - Low leakage preserves battery life in sleep-mode vehicle ECUs and telematics units. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; allows direct heatsinking via PCB copper pour under cathode pad. |
| CT | 200 pF @ 40 V, 1 MHz - Low junction capacitance minimizes switching noise in high-frequency (>100 kHz) SMPS designs. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case, UL 94V-0 rated, cathode indicated by band on body. Dimensions: 4.00–4.60 mm length × 2.29–2.92 mm width × 1.27–1.63 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or switch node); requires minimum 1.5 mm² copper pour for thermal relief. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to higher-potential rail (e.g., 12 V input); primary thermal path to PCB via exposed metal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche during voltage transients, improving reliability in noisy automotive environments. |
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| Lead-free & Halogen-free | Meets RoHS 2 and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb); compatible with Pb-free reflow profiles up to 260 °C/10 s. |
| Low VF / High efficiency | 0.50 V drop at 2.0 A yields >92% conduction efficiency vs. silicon diodes (~0.9 V), reducing heat sink need. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |
|---|---|
Use Scenario: Reverse polarity protection on 12 V input rail of BCM microcontroller power supply. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from incorrect battery connection.

Use Value: -65 to +150 °C TJ range supports under-hood mounting without derating at 85 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/54 (Vishay) | Same 30 V VRRM, 2.0 A IF, but SMB package (RθJL = 20 °C/W) and VF = 0.52 V @ 2.0 A. | SMB offers better thermal performance but larger footprint; less suitable for space-constrained SMA layouts. | Select when board-level thermal resistance dominates and PCB area permits SMB. |
| SS23 (ON Semiconductor) | 30 V VRRM, 2.0 A IF, SMA package, VF = 0.55 V @ 2.0 A, IR = 0.2 mA @ 25 °C - lower leakage but higher VF. | Better leakage spec suits ultra-low-power always-on nodes; higher VF increases conduction loss by ~10%. | Select when standby current budget is tighter than efficiency target in battery-backed modules. |
Compared with SB230-E3/54 and SS23, B230A-13-F delivers optimal balance of low VF (0.50 V), AEC-Q101 qualification, and SMA footprint - making it preferred for cost-sensitive, space-constrained automotive power rails where 0.05 V VF reduction directly lowers thermal load.

FAQ
What is the maximum junction temperature for continuous operation?
The B230A-13-F has an operating junction temperature range of –65 °C to +150 °C. For continuous 2.0 A operation, terminal temperature must remain ≤100 °C per Fig. 4 derating curve; this corresponds to ~75 °C ambient with standard FR-4 layout and 25 °C/W RθJL.
Is B230A-13-F pin-compatible with B230-13-F?
No - B230A-13-F uses the SMA (DO-214AC) package, while B230-13-F uses SMB (DO-214AA). Though electrically identical, their footprints differ: SMA is 4.60 × 2.92 mm, SMB is 4.57 × 3.94 mm. PCB layout must be revised for package swap.
Does this part support reflow soldering at 260 °C?
Yes - the B230A-13-F is qualified for high-temperature soldering at +260 °C for 10 seconds per J-STD-020, enabled by its lead-free matte tin plating and UL 94V-0 mold compound. No special pre-bake is required for standard moisture sensitivity level 1 handling.
How does the guard ring construction improve reliability?
The guard ring die structure confines high electric fields to the active junction region, suppressing premature edge breakdown during voltage transients like ISO 7637-2 pulse 1/2a. This extends operational life in automotive environments where load dump and jump-start surges exceed 60 V.
