Diodes Incorporated B360BE-13

Overview

B360BE-13 from Diodes Incorporated is a 60 V, 3 A surface-mount Schottky barrier rectifier in SMB package, featuring 0.65 V max forward voltage at 3 A and 0.2 mA max reverse leakage at 60 V/25°C. It delivers low conduction loss and stable high-temperature leakage for DC-DC boost stages, solar charge controllers, and 12 V/24 V automotive power supplies.

For engineers reviewing the B360BE-13 datasheet, B360BE-13 pinout, B360BE-13 application, or B360BE-13 equivalent, key selection criteria include its 60 V VRRM rating, SMB thermal resistance (90°C/W junction-to-ambient), 80 A non-repetitive surge capability, and RoHS-compliant matte tin finish on copper leadframe.

Technical Context

This Schottky rectifier uses a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve VF ≤ 0.65 V at IF = 3 A and TJ = 25°C, enabling higher efficiency than PN-junction diodes in medium-current switching applications. Its reverse leakage remains tightly bounded at 0.2 mA @ VR = 60 V/25°C and rises to only 25 mA @ VR = 60 V/125°C - critical for thermal stability in enclosed industrial power modules.

The device is rated for continuous 3 A average forward current with derating above 25°C ambient (e.g., ~1.8 A at 75°C), and supports 8.3 ms half-sine surge currents up to 80 A. Thermal design must account for SMB package RθJA = 90°C/W on standard FR-4 PCBs per JEDEC JESD51-3.

FAQ

What is the maximum junction temperature for continuous operation of B360BE-13?

The B360BE-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 - typically achieved with ≥0.2" × 0.25" copper pad on FR-4, limiting ambient to ~75°C at full load per Figure 4 derating curve.

Is B360BE-13 suitable for use in automotive under-hood applications?

Yes - B360BE-13 is qualified for automotive under-hood use per its –55°C to +150°C operating range and stable IR performance up to 125°C. Its 0.2 mA IR at 25°C and 25 mA at 125°C prevent thermal runaway in sealed engine-control modules, meeting AEC-Q101 stress-test expectations.

Does B360BE-13 require a heatsink for 3 A DC operation?

No external heatsink is required if mounted on a minimum 0.2" × 0.25" copper pad on 2 oz FR-4 PCB per JEDEC JESD51-3. At TA = 25°C, this achieves RθJA ≈ 90°C/W, resulting in ΔTJ ≈ 270°C - but derating curves limit usable current to ~3 A only at low ambient; at 75°C ambient, max continuous current drops to ~1.8 A.

How does the SMB package of B360BE-13 compare electrically to the SMC version (B360CE-13)?

B360BE-13 (SMB) and B360CE-13 (SMC) share identical electrical specs (60 V VRRM, 3 A IO, 0.65 V VF), but differ thermally: SMB has RθJA = 90°C/W and RθJC = 50°C/W, while SMC improves RθJA to 70°C/W and RθJC to 30°C/W - enabling higher current in thermally constrained layouts, though SMC occupies ~30% more PCB area.
