SBLB1630CTHE3/45

Diode Arrays Overview

The SBLB1630CTHE3/45 is a dual common cathode Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes TO-263AB surface-mount packaging and features an ITO-220AB variant within the same series. The device supports a maximum repetitive peak reverse voltage of 30 V and a working peak reverse voltage of 21 V. Each diode element provides a maximum average forward rectified current of 8 A, totaling 16 A for the device. It withstands a peak forward surge current of 250 A per diode with a maximum instantaneous forward voltage drop of 0.55 V at 8.0 A. The component operates within a junction temperature range of -40 to +125 °C.

Diode Arrays Feature Summary

• Guard ring structure designed for transient overvoltage protection
• AEC-Q101 qualified for automotive reliability standards
• LF soldering capability up to 245 °C for TO-263AB packages
• RoHS-compliant material categorization with HE3 suffix whisker test compliance

Diode Arrays Applications

• Low voltage, high frequency rectification in switching mode power supplies
• Free-wheeling diode circuits in DC/DC converters
• Polarity protection applications

Diode Arrays Procurement Notes

Verify that the ordering suffix /45 corresponds to tube delivery rather than tape and reel configurations. Confirm the HE3 designation indicates AEC-Q101 qualification status. Ensure the specific package type matches the required thermal resistance characteristics for the intended application environment.

Diode Arrays Selection Notes

Select this component when low forward voltage drop and high efficiency are critical for power loss reduction. Consider the TO-263AB package for surface mount assembly requirements. Evaluate the thermal resistance from junction to case to ensure adequate heat dissipation under continuous load conditions without exceeding the maximum junction temperature rating.

Diode Arrays Part Context

This part belongs to the SBL(F,B)1630CT family of dual common cathode Schottky rectifiers. The 'B' prefix specifically denotes the TO-263AB surface mount package configuration. The series includes variants with different reverse voltage ratings such as the 40 V version, sharing identical physical dimensions and electrical performance profiles except for blocking voltage specifications.

Diode Arrays Replacement Considerations

SBLB1630CT-E3/45 serves as the commercial grade equivalent lacking automotive qualification. SBLB1630CTHE3/81 offers the same electrical parameters but utilizes tape and reel packaging instead of tubes.

Diode Arrays FAQ

What is the isolation voltage specification for the TO-263AB package?

The datasheet specifies an isolation voltage only for the ITO-220AB package (1500 V AC). No isolation voltage rating is provided for the standard TO-263AB or SBLB variants.

How does the HE3 suffix affect the component's material properties?

The HE3 suffix indicates the product meets JESD 201 class 2 whisker test requirements, whereas the E3 suffix meets class 1 requirements. Both are RoHS compliant.

What is the typical thermal resistance from junction to case?

The typical thermal resistance from junction to case per diode is 2.0 °C/W for both the SBL and SBLB package types.
