Engineering Selection Recommendations

UGB10CCTHE3/81 - Parametric Equivalent

The UGB10CCTHE3/81 is a parametric equivalent to the BYQ28EB-150HE3_A/I. Both devices share identical electrical specifications: 150 V DC reverse voltage, 5 A average rectified current per diode, 1.1 V forward voltage at 5 A, and 25 ns reverse recovery time. Both are housed in the TO-263-3 D2PAK package and carry automotive-grade AEC-Q101 qualification. The UGB10CCTHE3/81 is currently in active production status, providing supply chain continuity for applications previously utilizing the obsolete BYQ28EB-150HE3_A/I. All compliance requirements including ROHS3 compliance and MSL 1 rating are identical.

STPS40170CGY-TR - Performance Upgrade

The STPS40170CGY-TR is a performance upgrade option manufactured by STMicroelectronics. This device exceeds the electrical specifications of the BYQ28EB-150HE3_A/I in current capacity (20 A versus 5 A) and voltage rating (170 V versus 150 V). The STPS40170CGY-TR utilizes Schottky technology, resulting in lower forward voltage (920 mV at 20 A) compared to the standard diode technology of the original part. The device maintains the same TO-263-3 D2PAK package, automotive-grade qualification (AEC-Q101), and compliance certifications. The extended operating temperature range (-40°C ~ 175°C) provides additional thermal margin. The STPS40170CGY-TR is suitable for applications requiring higher current capacity or voltage headroom while maintaining package compatibility and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can the UGB10CCTHE3/81 be used as a direct replacement for the BYQ28EB-150HE3_A/I?

A: Yes. The UGB10CCTHE3/81 is a parametric equivalent with identical electrical specifications, package configuration, and automotive qualification. No circuit modifications are required for direct substitution.
