Substitute Part Grouping Explanation

Substitute parts for the SBCT20100 are qualified based on strict parametric equivalence across the following criteria:

Electrical Parameters (Critical for Substitution):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io) (per Diode): 10 A
• Voltage - Forward (Vf) (Max) @ If: 850 mV @ 10 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Mechanical Parameters (Critical for Substitution):

• Mounting Type: Through Hole
• Package / Case: TO-220-3

All identified substitute parts match these core parameters, ensuring functional and mechanical compatibility in applications designed for the SBCT20100. Variations in reverse leakage current, maximum junction temperature, and compliance certifications do not affect substitutability for standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

SBCT20100 (Diotec Semiconductor): Primary selection for applications with no specific compliance requirements. Active product status with established supply availability (1109 pieces in stock). Suitable for general-purpose Schottky diode array applications in the 100 V, 10 A class.

MBR20H100CTG-E3/45 (Vishay General Semiconductor - Diodes Division): Qualified substitute offering ROHS3 compliance and REACH Unaffected status. Superior reverse leakage performance (3.5 µA vs. 300 µA) and extended maximum junction temperature (175°C vs. 150°C). Recommended for applications requiring environmental compliance certifications. Stock availability: 1150 pieces.

STPS20S100CT (STMicroelectronics): Qualified substitute offering ROHS3 compliance and REACH Unaffected status. Equivalent reverse leakage performance (3.5 µA) and extended maximum junction temperature (175°C). Highest stock availability (143620 pieces) ensures supply continuity. Recommended for high-volume production and applications requiring compliance certifications.

All three parts are electrically and mechanically interchangeable for standard circuit applications. Selection between substitutes is determined by compliance requirements, thermal operating conditions, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can STPS20S100CT replace SBCT20100 in my circuit?

A: Yes. The STPS20S100CT is a parametric equivalent with identical electrical ratings (100 V, 10 A, 850 mV forward voltage, Schottky technology) and mechanical compatibility (TO-220-3 Through Hole package). Both devices are configured as 1 Pair Common Cathode diode arrays with Fast Recovery characteristics.

Q: What is the difference between the three parts?

A: All three parts meet the core electrical and mechanical specifications. Differences exist in reverse leakage current (SBCT20100: 300 µA; MBR20H100CTG-E3/45 and STPS20S100CT: 3.5 µA each), maximum junction temperature (SBCT20100: 150°C; others: 175°C), and compliance certifications (SBCT20100: Not applicable; others: ROHS3 Compliant and REACH Unaffected).

Q: Are the pin configurations identical?

A: Yes. All three parts use the TO-220-3 package format with identical pin assignments for Through Hole mounting. Direct PCB footprint compatibility is confirmed.

Q: Which substitute should I select for a new design?

A: For new designs, STPS20S100CT or MBR20H100CTG-E3/45 are recommended due to ROHS3 compliance and REACH Unaffected status. STPS20S100CT offers the highest stock availability. Selection between these two is based on supplier preference and supply chain strategy.

Q: Can I use these parts interchangeably in existing production?

A: Yes, provided the circuit design does not depend on the specific reverse leakage characteristics of the SBCT20100 (300 µA). The lower leakage of substitute parts (3.5 µA) is generally beneficial and does not create compatibility issues.

Q: What is the significance of the TO-220-3 package designation?

A: TO-220-3 indicates a Through Hole package with three leads, suitable for manual or automated PCB assembly. All three parts use this identical package format, ensuring mechanical and thermal compatibility on the same PCB layout.

Q: Are there thermal considerations when substituting?

A: The substitute parts support higher maximum junction temperatures (175°C vs. 150°C for SBCT20100). This provides additional thermal margin in applications operating near the upper temperature limit. No thermal derating adjustments are required when substituting to the higher-rated parts.
