Diodes Incorporated B150AE-13

Overview

B150AE-13 from Diodes Incorporated is a 50 V, 1 A surface-mount Schottky barrier rectifier in SMA package, featuring 0.65 V max forward voltage at 1 A and 0.1 mA max reverse leakage at 50 V and +25°C, optimized for boost, blocking, and recirculating diode functions in DC-DC converters and power supplies.

For engineers reviewing the B150AE-13 datasheet, B150AE-13 pinout, B150AE-13 application, or B150AE-13 equivalent, key selection criteria include low VF for efficiency, high-temperature IR stability, RoHS-compliant matte tin terminations, and SMA package thermal resistance (95°C/W junction-to-ambient).

Technical Context

This Schottky rectifier uses a planar epitaxial construction to achieve low forward voltage drop and controlled reverse recovery behavior. Its 50 V peak repetitive reverse voltage rating supports use in 24 V and 36 V input power rails with margin.

Thermal design is enabled by its 95°C/W junction-to-ambient resistance on FR-4 PCBs and 45°C/W junction-to-case resistance, allowing 1 A continuous operation up to +85°C ambient with appropriate copper area.

FAQ

What is the maximum junction temperature for continuous operation of B150AE-13?

The B150AE-13 has an operating junction temperature range of –55°C to +150°C. For continuous 1 A operation, thermal design must ensure TJ stays within this limit-typically requiring ≤+85°C ambient with standard PCB layout per datasheet Note 5.

Is B150AE-13 compatible with lead-free reflow soldering processes?

Yes. B150AE-13 features matte tin annealed terminations and meets J-STD-020 moisture sensitivity Level 1, making it fully compatible with standard Pb-free reflow profiles up to 260°C peak temperature without preconditioning.

How does the reverse leakage of B150AE-13 compare at elevated temperatures?

At +125°C and VR = 50 V, B150AE-13 exhibits ≤8.0 mA typical reverse leakage-significantly lower than many competing Schottkys. This stability prevents thermal runaway in enclosed, high-ambient applications like motor drives and LED drivers.

Can B150AE-13 be used as a direct replacement for B150BE-13?

No. B150AE-13 uses the SMA package (smaller footprint, higher RθJA = 95°C/W), while B150BE-13 uses SMB (larger, lower RθJA = 90°C/W). Mechanical incompatibility and thermal derating differences require PCB layout changes; they are not drop-in replacements.
