Product details
Overview
B180BE-13 from Diodes Incorporated is a 1.0A, 80V high-voltage Schottky barrier rectifier in SMB package, featuring 0.79V max forward voltage at 1.0A and 0.2mA max reverse leakage at 25°C, optimized for polarity protection and DC-DC converter freewheeling paths in industrial power supplies.
For engineers reviewing the B180BE-13 datasheet, B180BE-13 pinout, B180BE-13 application, or B180BE-13 equivalent, key selection criteria include its 80V VRRM rating, low VF for reduced conduction loss, SMB thermal resistance (RθJA = 75°C/W), and RoHS-compliant matte tin plating suitable for automated reflow assembly.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient voltage immunity and suppress avalanche-induced failure during inductive switching events. Its low junction capacitance (27pF at 4V, 1MHz) supports high-frequency operation in DC-DC converters up to several hundred kHz.
The device operates across –55°C to +150°C with derated forward current above 25°C (e.g., ~0.7A at 100°C), and exhibits stable reverse leakage-5.0mA max at 125°C-enabling reliable blocking in elevated-temperature environments such as motor drive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 80 V - Sustains peak reverse voltage without breakdown in bridge or clamp configurations |
| IO (AV) | 1.0 A - Continuous DC output current capability under specified thermal conditions |
| VF (max) | 0.79 V @ 1.0A, 25°C - Limits conduction loss to ≤0.79W per diode in series power paths |
| IR (max) | 0.2 mA @ 80V, 25°C - Ensures minimal standby power loss in blocking applications |
| RθJA | 75 °C/W (SMB) - Enables 1.0A operation on standard FR-4 PCBs with 0.2"×0.25" copper pad |
| CT | 27 pF @ 4V, 1MHz - Reduces high-frequency switching noise and EMI in SMPS freewheeling paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB180-E3/5BT (Vishay) | Same 80V VRRM, 1.0A IO, but VF = 0.85V max; SMB package, RoHS-compliant | Higher VF increases conduction loss by ~75mW at 1A; identical thermal footprint | Select if Vishay supply chain alignment required; verify layout compatibility with slightly higher thermal rise |
| SS18 (ON Semiconductor) | 80V VRRM, 1.0A IO, VF = 0.82V max; SMA package (RθJA = 110°C/W), same RoHS status | SMA package raises junction temperature ~35°C higher than SMB at 1A; requires larger copper area | Choose only when board space mandates SMA; derate current to 0.65A for equivalent thermal performance |
Compared with SB180-E3/5BT and SS18, B180BE-13 delivers the lowest VF (0.79V) and best thermal resistance (75°C/W) in SMB, making it optimal for space-constrained, thermally demanding 1A freewheeling and polarity protection roles.

FAQ
What is the maximum operating temperature for B180BE-13?
The B180BE-13 has an operating junction temperature range of –55°C to +150°C. At ambient temperatures above 25°C, the average forward current must be linearly derated-e.g., to approximately 0.7A at 100°C-based on its RθJA of 75°C/W and thermal design of the PCB mounting pad.
Is B180BE-13 compatible with lead-free reflow soldering processes?
Yes. B180BE-13 features matte tin-plated terminals qualified to MIL-STD-202, Method 208, and is rated for standard Pb-free reflow profiles (peak temperature up to 260°C). Its SMB package meets J-STD-020 moisture sensitivity Level 1, eliminating bake requirements before assembly.
How does the guard ring construction improve reliability?
The guard ring die structure prevents edge breakdown under high dv/dt or repetitive voltage transients-common in motor drives and relay coils-by controlling electric field distribution at the silicon periphery. This extends operational life and avoids premature avalanche failure during inductive switching events.
Can B180BE-13 replace a standard PN junction rectifier in existing designs?
Yes, provided the circuit's reverse voltage requirement is ≤80V and forward current ≤1.0A. Its lower VF reduces conduction loss and self-heating, but note its higher IR at elevated temperatures (5.0mA at 125°C) versus PN diodes-verify blocking integrity in high-temp hold-off conditions.
