Diodes Incorporated B360AM-13-F

Overview

B360AM-13-F from Diodes Incorporated is a 3.0A, 60V surface-mount Schottky barrier rectifier in SMA package, featuring 0.70V max forward voltage at 3.0A/25°C, 0.10mA max reverse leakage at 60V/25°C, and AEC-Q101 qualification for automotive reliability. It serves as a low-loss freewheeling diode in DC-DC converters and polarity protection circuits.

For engineers reviewing the B360AM-13-F datasheet, B360AM-13-F pinout, B360AM-13-F application, or B360AM-13-F equivalent, key selection criteria include its low VF at high temperature, <0.1mA IR at rated VRRM, SMA thermal resistance (RθJL = 30°C/W), and suitability for 100°C junction-temperature operation in compact power stages.

Technical Context

This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche failure and sustain reliable operation under repetitive surge conditions (IFSM = 80A). Its low-leakage design maintains IR ≤2.4mA at 125°C - critical for high-temperature DC-DC converter output stages.

The device exhibits 130pF typical junction capacitance at 4V reverse bias and 1MHz, enabling fast switching with minimal capacitive loss in high-frequency (>100kHz) topologies. Thermal performance is defined by RθJA = 100°C/W on FR-4 (1×1 inch, 2 oz Cu) and RθJL = 30°C/W - confirming efficient heat transfer to PCB copper pads.

FAQ

What is the maximum junction temperature for continuous operation of B360AM-13-F?

The B360AM-13-F has a specified operating junction temperature range of –55°C to +150°C. For continuous operation at rated 3.0A IO, thermal design must ensure TJ does not exceed +150°C - achievable with RθJL = 30°C/W and adequate PCB copper area per the datasheet's 1×1 inch FR-4 recommendation.

Is B360AM-13-F compatible with lead-free reflow soldering processes?

Yes. B360AM-13-F features matte tin-plated terminals qualified to MIL-STD-202, Method 208, and is rated for lead-free reflow profiles up to 260°C peak. Its moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to assembly.

How does the guard ring construction improve reliability in real-world applications?

The guard ring die structure prevents premature edge breakdown during voltage transients - such as load dump or inductive kickback - by redistributing electric field stress away from the active junction periphery. This extends operational life in automotive DC-DC converters subjected to ISO 7637-2 pulse 5a/b.

Can B360AM-13-F replace standard silicon rectifiers in existing designs?

Yes, provided reverse voltage and surge current requirements are met. Its 60V VRRM and 80A IFSM allow direct substitution for 1N5822-class devices, but designers must verify reduced VF lowers thermal load and that lower IR avoids unintended biasing in multi-diode configurations.
