Diodes Incorporated B360Q-13-F

Overview

B360Q-13-F from Diodes Incorporated is a 60 V, 3.0 A surface-mount Schottky barrier rectifier optimized for automotive polarity protection and freewheeling applications. It features a maximum forward voltage of 0.70 V at 3.0 A, reverse leakage of ≤0.5 mA at 60 V and 25°C, and AEC-Q101 qualification for under-hood use.

For engineers reviewing the B360Q-13-F datasheet, B360Q-13-F pinout, B360Q-13-F application, or B360Q-13-F equivalent, key selection criteria include its 60 V reverse voltage rating, low 0.70 V forward drop at rated current, SMC package thermal resistance (R_θJT = 20 °C/W), and compliance with automotive change control and PPAP requirements.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient robustness in automotive environments. Its low forward voltage and fast switching enable high-efficiency operation in low-voltage DC/DC stages and inductive load snubbing circuits.

The device operates across –55°C to +150°C junction temperature range and exhibits 200 pF typical junction capacitance at 4 V reverse bias. Thermal performance is defined with R_θJA = 90 °C/W on glass-epoxy PCB with 2 mm × 3 mm copper pad.

FAQ

What is the maximum junction temperature for continuous operation of B360Q-13-F?

The B360Q-13-F has a specified operating junction temperature range of –55°C to +150°C. Continuous operation at +150°C requires adherence to derated current limits per Figure 6 in DS38534 Rev. 4-2, where average forward current drops to ~1.4 A at terminal temperatures above 100°C.

Is B360Q-13-F compatible with lead-free reflow soldering processes?

Yes. B360Q-13-F features matte tin-plated terminals and is qualified for lead-free reflow per JEDEC J-STD-020, with Moisture Sensitivity Level 1. Its SMC package withstands peak reflow temperatures up to 260°C for 30 seconds without degradation.

How does B360Q-13-F differ from B340Q-13-F in practical circuit design?

B360Q-13-F offers 60 V V_RRM versus 40 V for B340Q-13-F, making it suitable for 24 V commercial vehicle systems and higher-energy load dump scenarios. Both share identical 3.0 A I_O, but B360Q's 0.70 V V_F is 0.20 V higher than B340Q's 0.50 V, increasing conduction loss by ~0.6 W at full load.

Does B360Q-13-F require external transient voltage suppression in automotive applications?

No standalone TVS is required for basic reverse polarity or freewheeling functions, as its guard ring die and 100 A I_FSM provide inherent transient resilience. However, for ISO 7637-2 Pulse 5b (100 V/100 ms) or combined ESD + surge events, supplemental TVS protection remains recommended per system-level validation.
