• Voltage - DC Reverse (Vr) (Max): 100 V (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Package / Case: TO-220-3 or TO-220-3 Full Pack (mandatory match)

Secondary Compatibility Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 8 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (mandatory match)
• Operating Temperature - Junction: Minimum -55°C, Maximum ≥ 150°C
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

MBR16100CTG (onsemi)

The MBR16100CTG is a direct electrical equivalent to the SBT80-10JS, matching all mandatory substitution criteria. Both devices are manufactured by onsemi and share identical diode configuration, technology, voltage rating, current rating, and speed characteristics. The MBR16100CTG operates across an extended temperature range (-65°C to 175°C) compared to the SBT80-10JS (-55°C to 150°C), providing additional thermal margin. However, the MBR16100CTG is also classified as obsolete, limiting its long-term availability for new production requirements.

STPS20S100CFP (STMicroelectronics)

The STPS20S100CFP is a functionally compatible substitute with enhanced electrical performance characteristics. It maintains all mandatory substitution parameters: 1 Pair Common Cathode configuration, Schottky technology, 100 V reverse voltage rating, through-hole mounting, and TO-220-3 Full Pack packaging. The STPS20S100CFP provides a higher current rating of 10 A per diode compared to the 8 A rating of the SBT80-10JS, enabling operation in higher-current applications. The device exhibits superior reverse leakage characteristics (3.5 µA @ 100 V versus 100 µA @ 50 V) and operates at a maximum junction temperature of 175°C. Critically, the STPS20S100CFP is classified as active, ensuring ongoing availability and supply chain continuity. The device is RoHS3 compliant, supporting environmental and regulatory requirements.

For applications requiring immediate supply availability and long-term production support, the STPS20S100CFP is the preferred substitute. For applications requiring exact electrical matching with the original SBT80-10JS, the MBR16100CTG provides direct equivalence, subject to availability constraints.

Frequently Asked Questions (FAQ)

Q: Can the MBR16100CTG be used as a direct replacement for the SBT80-10JS?

A: Yes. The MBR16100CTG meets all mandatory substitution criteria: identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, 8 A average rectified current per diode, fast recovery speed, through-hole mounting, and TO-220-3 packaging. Both devices are manufactured by onsemi and share equivalent electrical performance characteristics.

Q: What are the advantages of using STPS20S100CFP over the SBT80-10JS?

A: The STPS20S100CFP provides three key advantages: (1) Active product status, ensuring ongoing availability and supply chain continuity; (2) Higher current rating of 10 A per diode, enabling operation in higher-current applications; (3) Superior reverse leakage characteristics (3.5 µA @ 100 V) and extended maximum junction temperature (175°C). The device is also RoHS3 compliant.

Q: Are there any electrical differences between the SBT80-10JS and STPS20S100CFP?

A: Both devices share identical voltage ratings (100 V reverse, Schottky technology) and mounting configuration (TO-220-3 through-hole). The STPS20S100CFP has a higher current rating (10 A versus 8 A per diode) and lower reverse leakage current (3.5 µA @ 100 V versus 100 µA @ 50 V). Forward voltage characteristics differ due to the higher current rating of the STPS20S100CFP.

Q: Can the STPS20S100CFP be used in applications originally designed for the SBT80-10JS?

A: Yes. The STPS20S100CFP is electrically compatible with the SBT80-10JS for all applications operating at or below 8 A per diode. The higher current rating of the STPS20S100CFP does not create incompatibility; it provides additional design margin. Both devices maintain identical reverse voltage ratings, diode configuration, and fast recovery speed characteristics.

Q: What is the significance of the TO-220-3 Full Pack versus TO-220-3 packaging designation?

A: Both designations refer to the same physical TO-220-3 through-hole package form factor. The "Full Pack" designation indicates the complete diode pair assembly in a single package. This distinction does not affect electrical compatibility or mechanical fit in circuit board designs.

Q: Are there any compliance or regulatory differences between these substitute parts?

A: All three parts (SBT80-10JS, MBR16100CTG, and STPS20S100CFP) are classified as REACH Unaffected and carry EAR99 ECCN designation. The STPS20S100CFP is RoHS3 compliant. All devices have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Why is the SBT80-10JS classified as obsolete?

A: The SBT80-10JS is listed as obsolete by the manufacturer. This classification indicates the part is no longer in active production. Substitute parts with active status, such as the STPS20S100CFP, are recommended for new designs and ongoing production to ensure supply chain continuity.
