Diodes Incorporated B330BE-13

Overview

B330BE-13 from Diodes Incorporated is a 30 V, 3 A surface-mount Schottky barrier rectifier in SMB package with max forward voltage of 0.50 V at 3 A and 0.15 mA reverse leakage at 30 V/25°C, used as a boost diode in DC-DC converters for power supplies and LED drivers.

For engineers reviewing the B330BE-13 datasheet, B330BE-13 pinout, B330BE-13 application, or B330BE-13 equivalent, key selection criteria include low VF for efficiency, high-temperature IR stability, SMB thermal resistance (90°C/W), and RoHS-compliant matte tin terminations.

Technical Context

This Schottky rectifier uses a planar metal-semiconductor junction to achieve low forward conduction loss and fast switching with no minority-carrier storage delay. Its low 0.50 V VF at 3 A directly reduces I²R losses in high-frequency switching topologies.

Reverse leakage remains tightly controlled up to +150°C (0.30 mA at 45 V/125°C), enabling stable operation in thermally constrained environments such as enclosed LED drivers and industrial power modules without thermal runaway risk.

FAQ

What is the maximum junction temperature for B330BE-13?

The absolute maximum junction temperature is +150°C, verified per datasheet thermal characteristics. Operation at this limit requires strict ambient control and PCB thermal design-typical derating begins above +75°C ambient, with IO reduced linearly to zero at +150°C per Figure 4.

Is B330BE-13 suitable for automotive applications?

B330BE-13 meets AEC-Q101 stress test requirements for discrete semiconductors and operates across –55°C to +150°C. It is qualified for under-hood and infotainment power stages but not for safety-critical ADAS or airbag systems without additional system-level validation.

Does B330BE-13 have a built-in thermal shutdown feature?

No. As a passive Schottky rectifier, B330BE-13 has no active circuitry or thermal protection. Safe operation relies entirely on external thermal design-including copper area, airflow, and adjacent heat sources-to maintain TJ ≤ 150°C under worst-case load and ambient conditions.

Can B330BE-13 replace a standard PN rectifier like 1N5822?

Yes-B330BE-13 is a direct functional replacement for 1N5822 (30 V/3 A) with superior performance: 0.50 V vs. 0.9 V typical VF, near-zero reverse recovery time, and lower IR. No circuit redesign is needed, though layout should verify SMB pad compatibility versus DO-201AD footprint.
