Diodes Incorporated B130BE-13

Overview

B130BE-13 from Diodes Incorporated is a 30 V, 1 A surface-mount Schottky barrier rectifier in SMB package, featuring 0.5 V max forward voltage at 1 A and 0.1 mA max reverse leakage at 30 V and +25°C. It delivers low-loss rectification in DC/DC converters, boost circuits, and reverse polarity protection for 5–24 V industrial power rails.

For engineers reviewing the B130BE-13 datasheet, B130BE-13 pinout, B130BE-13 application, or B130BE-13 equivalent, this device is selected for high-efficiency, thermally stable rectification where low VF and controlled IR at elevated temperature are critical design requirements.

Technical Context

This Schottky rectifier uses a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve reduced forward voltage drop versus PN-junction diodes. Its low R_θJA of 90°C/W (SMB) enables operation up to +150°C ambient without derating under typical PCB layout conditions.

The device exhibits minimal increase in reverse leakage up to +125°C - specified at ≤0.1 mA at VR = 30 V and TJ = +25°C, rising to ≤6.1 mA at TJ = +125°C - supporting reliable performance in thermally constrained environments such as enclosed power supplies and automotive under-hood modules.

FAQ

What is the maximum junction temperature for B130BE-13?

The absolute maximum junction temperature is +150°C, with continuous operation supported from –55°C to +150°C ambient. Derating begins above +25°C per Figure 4: at +100°C ambient, the average forward current must be reduced to approximately 0.7 A to maintain TJ ≤ 150°C using standard FR-4 PCB layout.

Is B130BE-13 suitable for use in automotive applications?

B130BE-13 meets AEC-Q200 stress test requirements for passive components and operates reliably from –55°C to +150°C, but is not AEC-Q101 qualified as a discrete semiconductor. It is used in non-safety-critical automotive subsystems (e.g., infotainment power rails, lighting drivers) where customer qualification confirms suitability.

How does the SMB package of B130BE-13 compare thermally to the SMA version (B130AE-13)?

The SMB package has R_θJA = 90°C/W versus 95°C/W for SMA, offering ~5% better thermal performance under identical PCB conditions. Its larger copper pad area (4.00 mm × 6.50 mm vs. 2.50 mm × 6.80 mm) improves heat spreading, making SMB preferable for sustained 1 A operation in thermally constrained designs.

Can B130BE-13 replace a 1N5819 in existing designs?

Yes - B130BE-13 matches 1N5819's 30 V VRRM and 1 A IO rating, but offers lower VF (0.5 V vs. 0.6 V typical), lower IR (0.1 mA vs. 1 mA), and SMB packaging instead of DO-41. Layout adaptation is required, and thermal validation is recommended due to different package thermal characteristics.
