Product details
Overview
B380CE-13 from Diodes Incorporated is a 80 V, 3.0 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.79 V max forward voltage at 3 A and 0.15 mA max reverse leakage at 80 V/25°C, optimized for boost, blocking, and recirculating diode roles in DC-DC converters and power supplies.
For engineers reviewing the B380CE-13 datasheet, B380CE-13 pinout, B380CE-13 application, or B380CE-13 equivalent, key selection criteria include thermal resistance (RθJC = 30°C/W), high-temperature reverse leakage stability, RoHS-compliant matte tin terminations, and SMC package compatibility with high-current PCB layouts.
Technical Context
This Schottky rectifier uses a planar epitaxial construction to achieve low VF and controlled junction capacitance (105 pF at 4 V, 1 MHz). Its low RθJC enables sustained 3 A operation under elevated ambient temperatures when mounted on standard FR-4 with recommended pad layout.
The device exhibits stable IR up to +150°C, with leakage rising to ≤0.7 mA at VR = 80 V and TA = +125°C - critical for reliability in thermally constrained power stages such as automotive body control modules and industrial SMPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse voltage before breakdown; sets safe operating margin for 48 V input systems. |
| IO (AV) | 3.0 A - Continuous average forward current rating at TA = +25°C with derating above 25°C per Figure 4. |
| VF Max | 0.79 V @ 3 A, +25°C - Enables >92% efficiency in 12 V → 5 V buck converters at full load. |
| IR Max | 0.15 mA @ 80 V, +25°C - Limits standby power loss in always-on circuits like USB-C PD controllers. |
| RθJC | 30°C/W - Allows direct heat transfer to heatsink or copper pour; supports 3 A operation up to +105°C case temperature. |
| CT | 105 pF @ 4 V, 1 MHz - Minimizes switching noise in high-frequency (>300 kHz) synchronous rectification. |
| IFSM | 100 A @ 8.3 ms - Withstands inrush currents during hot-plug events in telecom power modules. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with UL 94V-0 rating, matte tin–annealed copper leadframe, cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in boost converter); requires thermal relief pad for soldering. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by band; ties to output rail; must route with low-inductance path to minimize ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.79 V max @ 3 A ensures <0.24 W conduction loss, reducing thermal stress in compact 5 W–15 W adapters. |
| Stable high-temp IR | Leakage remains ≤0.7 mA at 80 V/125°C - avoids thermal runaway in sealed enclosures without forced air. |
| Green compound & RoHS | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb); compliant with EU RoHS 2 directive. |
| Optimized thermal interface | RθJC = 30°C/W enables direct mounting to 2 oz copper thermal pads, supporting 3 A continuous without external heatsink. |
Applications
| Boost Diode in DC-DC Converters | Blocking Diode in Solar Charge Controllers |
|---|---|
Use Scenario: Used in non-synchronous boost converters stepping 12 V battery to 24 V bus in automotive infotainment systems. IC Role / Device Role: Freewheeling path during MOSFET off-time; blocks reverse current when switch is on. Use Value: Low VF minimizes power loss at 3 A peak, while 80 V VRRM provides 2× safety margin over 24 V nominal output. | Use Scenario: Prevents reverse discharge of LiFePO₄ battery banks at night in off-grid solar installations. IC Role / Device Role: Unidirectional current gate between PV panel array and battery terminals. Use Value: 0.15 mA IR at 25°C limits nightly self-discharge to <0.01% capacity/day; SMC package withstands outdoor thermal cycling. |
| Recirculating Diode in Motor Drivers | Output Rectifier in AC-DC Adapters |
Use Scenario: Clamps inductive kickback from 24 V brushed DC motors in factory automation actuators. IC Role / Device Role: Provides low-loss return path for stored energy in motor windings during PWM turn-off. Use Value: 100 A IFSM absorbs 10 ms surge transients; 30°C/W RθJC sustains repeated 3 A pulses without thermal shutdown. | Use Scenario: Secondary-side rectification in 12 V/3 A wall adapters for networking equipment. IC Role / Device Role: Converts transformer secondary AC to regulated DC output. Use Value: 0.79 V VF improves light-load efficiency vs. standard PN diodes; SMC footprint fits tight 25 mm² board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS38-E3/57T (Vishay) | Same 80 V VRRM, 3 A IO, but VF = 0.85 V max @ 3 A; RθJC = 35°C/W. | Slightly higher conduction loss; less suitable for thermally dense 5 W adapters. | Prefer B380CE-13 where <0.79 V VF and 30°C/W thermal performance are required. |
| SB380-E3/57T (Vishay) | Identical VRRM/IO, but IR = 0.25 mA @ 80 V/25°C; SMB package (RθJA = 90°C/W). | Higher leakage reduces battery hold time; SMB limits current handling in sustained 3 A loads. | Choose B380CE-13 for SMC thermal robustness and tighter IR spec in mission-critical power rails. |
Compared with SS38-E3/57T and SB380-E3/57T, B380CE-13 delivers lower forward drop, superior thermal resistance, and tighter reverse leakage - making it optimal for space-constrained, high-reliability 3 A rectification where efficiency and thermal margin are prioritized.

FAQ
What is the maximum junction temperature for continuous operation?
The B380CE-13 has an operating junction temperature range of –55°C to +150°C. For continuous 3 A operation, thermal design must ensure TJ does not exceed +150°C - achievable with RθJC = 30°C/W and case temperature ≤ +105°C using recommended SMC pad layout on 2 oz copper.
Is B380CE-13 compatible with lead-free reflow profiles?
Yes. The device features matte tin–annealed copper leadframe terminations and green molding compound, fully compliant with IPC/JEDEC J-STD-020 moisture sensitivity Level 1 and RoHS 2. It supports standard lead-free reflow profiles up to peak 260°C, with no pre-bake required.
How does its reverse leakage compare to B370CE-13 at elevated temperature?
At 80 V and +125°C, B380CE-13 IR is rated ≤0.7 mA, versus B370CE-13's 0.7 mA limit at 70 V/125°C. Both exhibit similar thermal leakage behavior, but B380CE-13 maintains tighter specification margin at its higher VRRM rating due to optimized doping profile.
Can B380CE-13 replace B380BE-13 in existing designs?
Yes - both share identical electrical specs and SMC package. B380CE-13 differs only in marking code ('CE' denotes SMC; 'BE' denotes SMB) and thermal resistance (RθJC = 30°C/W vs. 50°C/W for SMB). PCB layout must accommodate larger SMC footprint and leverage its lower RθJC for improved thermal performance.
