Substitute Part Grouping Explanation

Substitution of the DSTB30200C is determined by the following critical parameters:

Mandatory Matching Parameters:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Voltage - DC Reverse (Vr) Max: 200V
Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
Mounting Type: Surface Mount

Allowable Variation Parameters:

Current - Average Rectified (Io): Substitute parts may have equal or higher current ratings (5A, 10A, 15A, 20A)
Voltage - Forward (Vf) Max: Acceptable within typical Schottky diode forward voltage range
Current - Reverse Leakage @ Vr: Acceptable within specified limits
Operating Temperature - Junction: May extend beyond -55°C to 150°C range

Engineering Selection Recommendations

For Active Product Status Applications:

Use MBRB20200CT, MBRB20200CT-13, MBRB20200CTT4G, STPS20200CG-TR, VB20202C-M3/4W, or MBRB20200CT-TP as primary substitutes. These parts maintain 200V reverse voltage rating, 1 Pair Common Cathode configuration, and TO-263/D2PAK packaging. MBRB20200CT and MBRB20200CT-13 from Diodes Incorporated carry AEC-Q101 automotive qualification. STPS20200CG-TR from STMicroelectronics offers the lowest forward voltage (860 mV @ 10A) and lowest reverse leakage (15 µA @ 200V). VB20202C-M3/4W from Vishay extends operating temperature to 175°C.

For Current Rating Compatibility:

Applications requiring ≤5A may use MBRB10200CT or MBRB10200CT-13. Applications requiring 10A to 15A may use MBRB20200CT, MBRB20200CT-13, MBRB20200CTT4G, STPS20200CG-TR, or VB20202C-M3/4W. Applications requiring up to 20A may use MBRB20200CT-TP.

Avoid Obsolete Parts:

MBRB20200CTG from onsemi is marked Obsolete and should not be selected for new designs, despite active inventory availability.

For Compliance Requirements:

All substitute parts listed are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) rating, matching the original DSTB30200C specifications.

Frequently Asked Questions (FAQ)

Q: Can MBRB10200CT substitute for DSTB30200C in all applications?

A: MBRB10200CT is suitable only for applications requiring ≤5A average rectified current per diode. The DSTB30200C is rated for 15A. If your application requires the full 15A capability, use MBRB20200CT, MBRB20200CT-13, MBRB20200CTT4G, STPS20200CG-TR, VB20202C-M3/4W, or MBRB20200CT-TP instead.

Q: What is the difference between MBRB20200CT and MBRB20200CT-13?

A: Both parts are identical in electrical specifications and performance. The difference is packaging format: MBRB20200CT is supplied in Tube packaging, while MBRB20200CT-13 is supplied in Tape & Reel (TR) format. Select based on your assembly process requirements.

Q: Why does VB20200G-E3/4W have a higher forward voltage (1700 mV) compared to other substitutes?

A: VB20200G-E3/4W is a TMBS® technology variant from Vishay. While it maintains the same 200V reverse voltage and 10A current rating, its forward voltage characteristic differs from standard Schottky diodes. Verify thermal and efficiency requirements before selection.

Q: Is MBRB20200CTG suitable for new designs?

A: No. MBRB20200CTG is marked Obsolete. Use MBRB20200CTT4G from onsemi instead, which is Active and offers identical electrical specifications with current availability.

Q: Can I use STPS20200CG-TR if my application operates below -40°C?

A: No. STPS20200CG-TR has a minimum operating junction temperature of -40°C. If your application requires operation at -55°C, use DSTB30200C, MBRB20200CT, MBRB20200CT-13, MBRB20200CTT4G, or VB20202C-M3/4W instead.

Q: Are all substitute parts in the same TO-263/D2PAK package family?

A: Yes. All listed substitute parts use TO-263-3, D2PAK (2 Leads + Tab), or TO-263AB packaging, ensuring mechanical and thermal compatibility with DSTB30200C PCB layouts.

Q: Which substitute offers the best reverse leakage performance?

A: STPS20200CG-TR from STMicroelectronics offers the lowest reverse leakage at 15 µA @ 200V, compared to 160 µA for DSTB30200C and 100-150 µA for most other substitutes.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 Compliant and REACH Unaffected, matching the environmental compliance of DSTB30200C.
