Diodes Incorporated B160BE-13

Overview

B160BE-13 from Diodes Incorporated is a 60 V, 1 A surface-mount Schottky barrier rectifier in SMB package, featuring 0.65 V max forward voltage at 1 A and 0.2 mA max reverse leakage at 60 V/25°C, optimized for boost, blocking, and recirculating diode functions in DC-DC converters and power supplies.

For engineers reviewing the B160BE-13 datasheet, B160BE-13 pinout, B160BE-13 application, or B160BE-13 equivalent, key selection criteria include thermal resistance (R_θJA = 90°C/W), high-temperature reverse leakage stability up to +150°C, and RoHS-compliant matte tin–annealed copper leadframe solderability per MIL-STD-202.

Technical Context

This Schottky rectifier uses a planar epitaxial construction with low-barrier metal–semiconductor junction to achieve reduced forward voltage drop and minimized minority-carrier storage effects. Its design eliminates recovery time and associated switching losses, making it suitable for high-frequency rectification in SMPS topologies.

The device operates across –55°C to +150°C with stable leakage performance: IR ≤ 8.0 mA at 60 V and +125°C. Thermal management relies on low R_θJC = 40°C/W (SMB) and defined PCB pad layout per Diodes Inc. recommended footprint.

FAQ

What is the maximum junction temperature for continuous operation of B160BE-13?

The B160BE-13 has an operating junction temperature range of –55°C to +150°C. Continuous operation at T_J = +150°C is permissible only if thermal design ensures actual junction temperature remains within this limit under worst-case ambient and power dissipation conditions, verified via R_θJA = 90°C/W and measured power loss.

Is B160BE-13 pin-compatible with SMA-package variants like B160AE-13?

No - B160BE-13 uses the SMB package (4.06–4.57 mm length), while B160AE-13 uses SMA (2.29–2.92 mm length). Though both are 2-terminal Schottky rectifiers with identical anode/cathode polarity, their footprints, thermal resistance (R_θJA 90 vs. 95°C/W), and PCB pad layouts are mechanically incompatible without board redesign.

Does B160BE-13 require derating for capacitive loads?

Yes - per datasheet note, average forward current must be derated by 20% when used with capacitive loads due to high inrush current peaks. At nominal 1 A rating, this means limiting continuous I_O to 0.8 A in applications such as bulk-input capacitor charging after cold start or hot-swap events.

How does the 45 pF junction capacitance affect EMI performance in switching applications?

The typical 45 pF C_T at 4 V/1 MHz contributes to high-frequency displacement current during voltage transitions. In boost or flyback outputs, this capacitance couples switching edges into ground planes, increasing common-mode noise - requiring careful layout separation from sensitive analog traces and proper Y-capacitor placement to meet CISPR-32 Class B limits.
