Diodes Incorporated B360AF-13

Overview

B360AF-13 from Diodes Incorporated is a 60 V, 3 A surface-mount Schottky barrier rectifier in SMAF package, featuring 0.65 V max forward voltage at 3 A and 0.2 mA max reverse leakage at 60 V/25°C, optimized for boost, blocking, and recirculating diode roles in DC-DC converters and power supplies.

For engineers reviewing the B360AF-13 datasheet, B360AF-13 pinout, B360AF-13 application, or B360AF-13 equivalent, key selection criteria include its low VF for efficiency-critical 3 A rectification, high-temperature IR stability up to +150°C, RoHS-compliant matte tin terminals, and SMAF thermal resistance (RθJA = 90°C/W) on FR-4 PCBs.

Technical Context

This Schottky rectifier uses a planar epitaxial construction with low-barrier metal-semiconductor junction to achieve minimal conduction loss. Its VF remains stable across temperature (0.52 V typ. at 3 A/125°C), and reverse leakage stays below 0.2 mA at rated VR and 25°C - critical for thermal runaway avoidance in compact power stages.

The device operates within -55°C to +150°C junction range and supports 80 A non-repetitive surge current (8.3 ms half-sine). Its 110 pF typical junction capacitance at 4 V/1 MHz enables fast switching in high-frequency SMPS topologies without excessive ringing.

FAQ

What is the maximum junction temperature for continuous operation of B360AF-13?

The B360AF-13 has a specified operating junction temperature range of -55°C to +150°C. At 3 A DC current and 25°C ambient on a standard FR-4 board, junction temperature rises approximately 315°C (3 A² × RθJA × 90°C/W), but actual rise is limited by thermal saturation and derating curves - Figure 4 shows usable IO drops to ~1.8 A at 100°C ambient. Full-rated 3 A operation requires ambient ≤75°C with proper copper area.

Is B360AF-13 compatible with lead-free reflow soldering processes?

Yes. B360AF-13 features matte tin annealed terminals over copper leadframe and complies with J-STD-020 Level 1 moisture sensitivity. It supports peak reflow temperatures up to 260°C per JEDEC standards, with no pre-baking required. The SMAF package's UL 94V-0 rating ensures flame resistance during soldering.

How does the reverse leakage of B360AF-13 compare at elevated temperatures?

At 60 V reverse bias, IR is 0.2 mA max at +25°C and increases to 24 mA max at +125°C (per datasheet Note 6). This controlled increase - versus exponential runaway in older Schottky designs - results from optimized barrier height and junction geometry, enabling reliable operation in automotive engine compartments or industrial enclosures up to 105°C ambient.

Can B360AF-13 replace B350AF-13 in existing designs?

Yes, with design verification. Both share identical SMAF package, pinout, and thermal characteristics, but B360AF-13 has 60 V VRRM vs. B350AF-13's 50 V. Substitution is safe if circuit reverse voltage never exceeds 50 V; however, using B360AF-13 provides 20% higher margin against transients or tolerance stack-up in 48 V systems without changing layout or thermal design.
