B370Q-13-F

Overview

The B370Q-13-F is a single Schottky Barrier Rectifier manufactured by Diodes Incorporated. It features a maximum average rectified output current of 3.0 A and a peak repetitive reverse voltage of 70 V. The device exhibits a maximum forward voltage drop of 0.79 V at 25°C and a maximum leakage current of 0.5 mA at rated voltage. It supports a non-repetitive peak forward surge current of 100 A and operates within a junction temperature range of -55°C to +150°C. The component utilizes an SMC (DO-214AB) surface-mount package.

Feature Summary

• Guard ring die construction provides transient protection capabilities
• Low power loss design ensures high efficiency in operation
• Qualified for automotive applications with AEC-Q101 standards and PPAP capability

Applications

• Polarity protection diodes
• Re-circulating diodes
• Switching diodes
• Free wheeling circuits
• Low-voltage, high-frequency inverters

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel packaging quantity. Confirm that the selected component meets the necessary RoHS compliance requirements for your target market regulations. Ensure the manufacturing facility adheres to IATF 16949 standards if automotive qualification is strictly required for the final assembly process.

Selection Notes

Select this component when a 70 V blocking voltage is required alongside a 3 A continuous current rating. Consider the thermal resistance characteristics for heat dissipation planning in enclosed environments. Evaluate the low forward voltage drop benefits for improving overall system efficiency compared to standard silicon rectifiers.

Part Context
