Product details
Overview
B380-13-F from Diodes Incorporated is a 3.0A, 80V peak repetitive reverse voltage Schottky barrier rectifier in SMC package, featuring low forward voltage drop (0.79 V at 3.0A, 25°C), 100A non-repetitive surge rating, and guard ring die construction for transient protection. It is used in low-voltage, high-frequency inverters, freewheeling diode circuits, and polarity protection in DC power supplies.
For engineers reviewing the B380-13-F datasheet, B380-13-F pinout, B380-13-F application, or B380-13-F equivalent, key selection factors include forward voltage at operating current, thermal resistance (10°C/W junction-to-terminal), reverse leakage (0.5 mA @ 80V, 25°C), surge capability (100A, 8.3ms), and SMC package compatibility with high-power surface-mount layouts.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve transient robustness under voltage surges. Its low VF and fast switching enable high-efficiency operation in 50–100 kHz DC-DC converters and synchronous rectification auxiliary paths.
Thermal performance is defined by RθJT = 10°C/W and a maximum junction temperature of +125°C, with derating beginning at TT = 90°C. Reverse leakage rises to 20 mA at 100°C, requiring thermal-aware layout in enclosed environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse voltage before avalanche; sets upper limit for DC bus or flyback clamp voltage |
| IO (AV) | 3.0 A @ TT = 90°C - Continuous average forward current rating under real-world heatsink-limited conditions |
| VF | 0.79 V @ IF = 3.0A, TA = 25°C - Directly determines conduction loss (2.37 W per device at full load) |
| IFSM | 100 A @ 8.3 ms - Withstands single-line surge events such as hot-plug or capacitor inrush without failure |
| RθJT | 10 °C/W - Enables thermal modeling of junction temperature rise above terminal temperature in PCB copper design |
| IR | 0.5 mA @ VR = 80V, TA = 25°C - Low leakage preserves efficiency in standby or battery-backed systems |
| CT | 100 pF @ VR = 4V, f = 1 MHz - Limits high-frequency displacement current in snubberless switching nodes |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic case with UL 94V-0 flammability rating, matte tin-plated terminals, cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in buck converter); requires low-inductance trace routing |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to higher-potential rail (e.g., output capacitor positive); critical for EMI control |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche, enabling stable 80V blocking without premature breakdown under dv/dt stress |
| Low VF at rated current | 0.79 V at 3.0A/25°C reduces conduction loss by ~35% vs. comparable silicon rectifiers |
| 100A surge rating | Supports IEC 61000-4-5 Level 3 surge immunity testing without external clamping |
| Lead-free & halogen-free | RoHS-compliant matte tin plating and green molding compound meet IPC-J-STD-020 moisture sensitivity Level 1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH02-M3/45 | Same 80V VRRM, but 2.0A IO rating and TO-277 package (lower thermal resistance: 7.5°C/W) | Lower current capacity limits use to ≤2A designs; TO-277 requires different footprint and stencil | Select when board space allows larger footprint and thermal margin is prioritized over current density |
| ON Semiconductor SB380-E3/54 | Identical 3.0A/80V rating and SMC package, but VF = 0.85V (25°C) and IR = 1.0 mA (25°C) | Higher conduction loss (+0.18 W at 3A) and leakage may impact low-power standby efficiency | Acceptable for cost-sensitive, non-thermal-limited applications where 6% VF penalty is tolerable |
Compared with VS-3EYH02-M3/45 and SB380-E3/54, B380-13-F delivers optimal balance of current rating, VF, and SMC footprint-enabling 3A operation with minimal board area and predictable thermal rise in standard 2-layer layouts.

FAQ
What is the maximum junction temperature for B380-13-F?
The absolute maximum junction temperature is +125°C. Operation above this value risks permanent degradation of the Schottky junction. Derating begins at terminal temperature (TT) = 90°C, where average forward current drops linearly to zero at 125°C junction, per Fig. 3 in DS30020 Rev. 14-2.
Can B380-13-F replace a standard PN junction rectifier in a 24V input buck converter?
Yes-its 80V VRRM exceeds typical 24V system transient requirements (e.g., ISO 7637-2 Pulse 1: −150V), and 0.79V VF at 3A yields ~35% lower conduction loss than a comparable 1N5822. However, reverse leakage (0.5 mA at 25°C) is higher than PN types, so verify standby current budgets.
Is the SMC package of B380-13-F compatible with IPC-7351B land patterns?
Yes-the SMC outline matches IPC-7351B "DO-214AB" generic footprint. Recommended pad dimensions are 3.3 mm × 2.5 mm (X/Y), with 6.8 mm center-to-center spacing (C), matching the official Diodes SMC suggested pad layout in DS30020 Rev. 14-2, page 4.
Does B380-13-F require derating when mounted on a 1-layer FR-4 PCB?
Yes-RθJT = 10°C/W assumes adequate copper pour. On a 1-layer board with minimal copper, junction temperature rise will exceed specification. For 3.0A continuous operation, ≥1 oz copper on both sides with ≥250 mm² thermal pad is required to maintain TJ ≤ 125°C at TA = 70°C.
