Substitute Part Grouping Explanation

Substitute parts for the BYQ28EB-200HE3_A/I are selected based on strict electrical and mechanical parameter compatibility. The following criteria determine substitution eligibility:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 200 V minimum (equal or higher acceptable)
• Current - Average Rectified (Io) (per Diode): 5 A minimum (equal or higher acceptable)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) (mandatory match)

Secondary Compatibility Factors:

• Operating Temperature Range: Must support minimum -40°C to 150°C junction temperature
• RoHS Status: ROHS3 Compliant (mandatory match)
• Automotive Grade and AEC-Q101 Qualification (preferred for automotive applications)

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical specifications with active product status) and Manufacturer Recommended Substitutes (enhanced specifications or alternative technologies meeting or exceeding primary criteria).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent - Direct Replacement:

The UGB10DCTHE3/81 from Vishay General Semiconductor - Diodes Division is a parametric equivalent to the BYQ28EB-200HE3_A/I. This part maintains identical electrical specifications (200 V reverse voltage, 5 A average rectified current, 1.1 V forward voltage at 5 A, 25 ns reverse recovery time) and identical package configuration (TO-263-3, D2PAK). The UGB10DCTHE3/81 carries Active product status, ensuring long-term availability and supply chain continuity. Both parts are Automotive Grade with AEC-Q101 qualification and ROHS3 compliance. This substitute is suitable for direct replacement in existing designs without circuit modification.

Manufacturer Recommended Substitutes - Enhanced Current Capability:

The SBR10200CTB-13-G from Diodes Incorporated provides equivalent 5 A current rating with identical 200 V reverse voltage and TO-263-3 D2PAK package. This part employs Super Barrier technology, delivering lower forward voltage (920 mV at 5 A versus 1.1 V) and faster reverse recovery time (20 ns versus 25 ns). Extended operating temperature range (-65°C to 175°C) and Active product status support long-term deployment. This substitute is suitable for applications requiring improved thermal performance and reduced power dissipation.

The FFB20UP20DN-F085 from onsemi, SBR20A200CTB, and SBR20A200CTB-13 from Diodes Incorporated provide 10 A average rectified current per diode while maintaining 200 V reverse voltage and TO-263-3 D2PAK package compatibility. These parts support higher current applications and deliver improved thermal headroom. All three maintain Active product status, ROHS3 compliance, and extended operating temperature ranges. These substitutes are suitable for applications requiring increased current capacity or thermal margin.

Alternative Technology - Schottky Rectifier:

The STPS40170CGY-TR from STMicroelectronics is a Schottky diode array providing 20 A average rectified current with 170 V reverse voltage rating in TO-263-3 D2PAK package. This part features lower forward voltage (920 mV at 20 A) and Automotive Grade with AEC-Q101 qualification. The 170 V reverse voltage rating is lower than the original 200 V specification and requires circuit evaluation for voltage margin adequacy. This substitute is suitable for applications where the 170 V reverse voltage rating is acceptable and higher current capacity is required.

Frequently Asked Questions (FAQ)

Q: Can the UGB10DCTHE3/81 be used as a direct replacement for the BYQ28EB-200HE3_A/I?

A: Yes. The UGB10DCTHE3/81 is a parametric equivalent with identical electrical specifications and package configuration. Both parts feature 200 V reverse voltage, 5 A average rectified current, 1.1 V forward voltage at 5 A, and TO-263-3 D2PAK surface mount packaging. The UGB10DCTHE3/81 carries Active product status, ensuring supply availability.

Q: What is the difference between the standard diode array and the Super Barrier technology variants?

A: Super Barrier technology (SBR10200CTB-13-G, SBR20A200CTB, SBR20A200CTB-13) reduces forward voltage drop and reverse recovery time compared to standard technology. The SBR10200CTB-13-G achieves 920 mV forward voltage at 5 A (versus 1.1 V for standard) and 20 ns reverse recovery time (versus 25 ns). These improvements reduce power dissipation and switching losses, beneficial for high-frequency or high-current applications.

Q: Are all substitute parts compatible with automotive applications?

A: The UGB10DCTHE3/81, FFB20UP20DN-F085, and STPS40170CGY-TR carry Automotive Grade classification with AEC-Q101 qualification, matching the original part. The SBR10200CTB-13-G, SBR20A200CTB, and SBR20A200CTB-13 do not specify Automotive Grade or AEC-Q101 qualification in the provided data. For automotive applications requiring formal qualification, the UGB10DCTHE3/81 is the recommended parametric equivalent.

Q: What is the significance of the 170 V reverse voltage rating on the STPS40170CGY-TR?

A: The STPS40170CGY-TR features a 170 V reverse voltage rating, which is lower than the original 200 V specification. This part is suitable only for applications where the circuit design accommodates the reduced voltage margin. Circuit evaluation is required to confirm that the 170 V rating provides adequate safety margin for the intended application voltage levels.

Q: Can higher-current substitutes (10 A or 20 A) be used in place of the 5 A original part?

A: Yes. Higher-current rated parts (FFB20UP20DN-F085 at 10 A, SBR20A200CTB/SBR20A200CTB-13 at 10 A, STPS40170CGY-TR at 20 A) are electrically compatible with circuits designed for 5 A operation. These parts provide additional thermal margin and current capacity without circuit modification. The lower forward voltage characteristics of these substitutes may reduce power dissipation in the application.

Q: What packaging options are available for these substitute parts?

A: All substitute parts are packaged in TO-263-3 (D2PAK) surface mount configuration, matching the original BYQ28EB-200HE3_A/I package. Packaging variants differ in tape format: UGB10DCTHE3/81 is supplied in standard packaging, FFB20UP20DN-F085 in Tape & Reel (TR), SBR10200CTB-13-G in Tape & Reel (TR), SBR20A200CTB in Tube, SBR20A200CTB-13 in Tape & Reel (TR), and STPS40170CGY-TR in Cut Tape (CT) & Digi-Reel®. PCB footprint compatibility is identical across all variants.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (UGB10DCTHE3/81, FFB20UP20DN-F085, SBR10200CTB-13-G, SBR20A200CTB, SBR20A200CTB-13, STPS40170CGY-TR) are ROHS3 compliant, matching the original part's environmental compliance status.

Q: What is the operating temperature range difference between the original part and substitutes?

A: The original BYQ28EB-200HE3_A/I operates from -40°C to 150°C junction temperature. Most substitutes extend this range: UGB10DCTHE3/81 maintains -40°C to 150°C, while FFB20UP20DN-F085, SBR10200CTB-13-G, SBR20A200CTB, and SBR20A200CTB-13 extend to -55°C to -65°C minimum and 175°C maximum. STPS40170CGY-TR operates from -40°C to 175°C. Extended temperature ranges provide additional design margin for extreme environment applications.
