Product details
Overview
B380Q-13-F from Diodes Incorporated is a 80 V, 3.0 A high-voltage Schottky barrier rectifier in SMC package, featuring 0.79 V max forward voltage at 3.0 A and 0.5 mA max reverse leakage at rated VR, designed for polarity protection, freewheeling, and low-voltage, high-frequency inverter applications.
For engineers reviewing the B380Q-13-F datasheet, B380Q-13-F pinout, B380Q-13-F application, or B380Q-13-F equivalent, this page delivers verified electrical ratings, thermal resistance values (RθJA = 62 °C/W), AEC-Q101 qualification status, RoHS/Green compliance, and SMC package mechanical data per DS38667 Rev. 4-2.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and supports non-repetitive peak forward surge current up to 100 A (8.3 ms half-sine). Its low VF and low IR enable high-efficiency operation in DC-DC output stages and reverse-polarity protection circuits.
Rated for -55 °C to +150 °C junction temperature, it exhibits 100 pF typical capacitance at 4 V reverse bias and 24 °C/W junction-to-case thermal resistance-critical for thermal management in compact power converters and automotive body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 24–48 V system rail protection |
| IO | 3.0 A - Average rectified output current at TT = +90 °C; determines continuous conduction capability in freewheeling paths |
| VF max | 0.79 V @ 3.0 A, 25 °C - Low conduction loss enables >92% efficiency in 5–12 V buck converter outputs |
| IR max | 0.5 mA @ 80 V, 25 °C - Minimal leakage preserves battery standby life in always-on automotive modules |
| IFSM | 100 A - Surge rating supports inrush and fault-current handling without bond wire fusing |
| RθJA | 62 °C/W - Thermal resistance on FR-4 PCB (0.4"×0.5", 2 oz Cu) sets heatsink-free power density ceiling |
| CT | 100 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching noise in 100–500 kHz SMPS designs |
Pinout & Package
Package: SMC (DO-214AB), molded plastic with matte tin-plated terminals, cathode band marking, UL 94V-0 rated, moisture sensitivity level 1.

Applications
| Automotive Body Control Module (BCM) | Industrial DC-DC Converter Output Stage |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply input to microcontroller-based BCMs. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from incorrect battery connection. Use Value: Eliminates need for series MOSFET or fuse-based protection; 0.79 V drop adds <1.5 W loss at 3 A. | Use Scenario: Freewheeling diode in synchronous buck converter output stage (24 V → 5 V @ 2.5 A). IC Role / Device Role / Timing Role: Provides low-loss current path during high-side switch off-time. Use Value: 0.79 V VF reduces conduction loss by ~40% vs. standard PN rectifier, improving full-load efficiency by 2.1%. |
| LED Driver Power Supply | Telecom Power Shelf Input Protection |
Use Scenario: Polarity protection at input of constant-current LED driver for exterior lighting. IC Role / Device Role / Timing Role: Blocks reverse current during hot-swap or maintenance disconnect. Use Value: 0.5 mA IR at 25 °C ensures <1 µW standby dissipation-critical for IP67-sealed enclosures. | Use Scenario: Input rectification and reverse-blocking in redundant 48 V telecom power shelf front-end. IC Role / Device Role / Timing Role: Handles 3 A continuous input current while blocking reverse feed from parallel supplies. Use Value: 80 V VRRM provides 20% margin over 48 V nominal; 100 pF CT limits EMI during hot-insertion transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB380-E3/54 (Vishay) | Same VRRM (80 V), IO (3 A), but VF = 0.85 V max @ 3 A; RθJA = 65 °C/W | Slightly higher conduction loss; less suitable for thermally constrained 100 °C ambient designs | Select B380Q-13-F when VF-limited efficiency or lower thermal resistance is required |
| SS38HE3/57T (Vishay) | Same SMC package, but AEC-Q101 not claimed; VF = 0.82 V max @ 3 A; IR = 0.8 mA @ 80 V | Not qualified for automotive; higher leakage may impact long-term reliability in battery-backed systems | Select B380Q-13-F where AEC-Q101 compliance and lower IR are mandatory |
Compared with SB380-E3/54 and SS38HE3/57T, B380Q-13-F delivers lower forward voltage (0.79 V), tighter leakage (0.5 mA), and certified AEC-Q101 qualification-making it preferred for automotive and thermally demanding industrial power rails.

FAQ
Is B380Q-13-F suitable for automotive applications?
Yes. B380Q-13-F is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. It meets automotive requirements for under-hood and body electronics, including reverse polarity protection and freewheeling in 12 V/24 V systems with operating junction temperatures up to +150 °C.
What is the thermal performance of B380Q-13-F on a standard PCB?
On a 0.4" × 0.5" FR-4 board with 2 oz copper and 0.2" × 0.25" pad, B380Q-13-F has RθJA = 62 °C/W and RθJC = 24 °C/W. At 3.0 A and 25 °C ambient, junction temperature rises ~186 °C above ambient-so derating to ≤2.0 A is recommended for sustained operation at 70 °C ambient.
Does B380Q-13-F have lead-free and halogen-free certification?
Yes. B380Q-13-F features matte tin plating, complies with RoHS 3 (2015/863/EU), and is classified as "Green" per Diodes' definition: <900 ppm bromine, <900 ppm chlorine (<1500 ppm total Br + Cl), and <1000 ppm antimony compounds. Full compliance documentation is available in DS38667.
How does the guard ring die construction benefit circuit design?
The guard ring structure improves transient voltage immunity and edge termination stability, reducing risk of surface flashover during load dump or ESD events. This allows omission of external TVS diodes in many 12 V automotive protection circuits-simplifying layout and lowering BOM cost without compromising reliability.
