Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBR30100CTU is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Package / Case: TO-220-3
• Mounting Type: Through Hole
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Allowable Variation Parameters:

• Current - Average Rectified (Io): May vary based on application requirements
• Voltage - Forward (Vf) (Max) @ If: Minor variations acceptable within thermal design margins
• Current - Reverse Leakage @ Vr: Lower values represent improved performance
• Operating Temperature - Junction: Extended ranges provide design flexibility

The identified substitute parts NTSV30H100CTG and STPS60H100CT maintain all critical matching parameters while offering different current ratings and reverse leakage characteristics.

Engineering Selection Recommendations

MBR30100CTU (Primary Selection) The MBR30100CTU remains the preferred component for new designs and existing applications. This part maintains active product status with established supply availability and full ROHS3 compliance. The component is suitable for applications requiring 100 V reverse voltage with Schottky diode performance characteristics in a TO-220-3 package.

STPS60H100CT (Preferred Substitute) The STPS60H100CT from STMicroelectronics is the recommended substitute when MBR30100CTU availability is constrained. This part maintains active product status with significantly higher inventory levels (90300 units). The STPS60H100CT provides superior reverse leakage performance (10 µA versus 1 mA) and higher current rating (30 A per diode). All critical electrical and mechanical parameters align with the MBR30100CTU, including 100 V reverse voltage rating, Schottky technology, TO-220-3 package, and fast recovery speed. ROHS3 compliance and unlimited moisture sensitivity level are maintained.

NTSV30H100CTG (Secondary Substitute) The NTSV30H100CTG from onsemi is available as a secondary substitute option with 2200 units in stock. This part is designated as obsolete product status, indicating limited long-term availability. The NTSV30H100CTG maintains electrical compatibility with 100 V reverse voltage and Schottky technology in TO-220-3 package format. Reverse leakage performance (95 µA) is superior to the MBR30100CTU. Operating temperature range is narrower (-40°C to 150°C versus -55°C to 150°C). ROHS3 compliance is maintained. This substitute is suitable for applications where the narrower temperature range is acceptable and where supply of the primary part is unavailable.

Frequently Asked Questions (FAQ)

Q: Can STPS60H100CT be used as a direct replacement for MBR30100CTU?

A: Yes. The STPS60H100CT is electrically and mechanically compatible with the MBR30100CTU. Both components share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, TO-220-3 package, and fast recovery speed characteristics. The STPS60H100CT provides higher current rating (30 A versus unspecified for MBR30100CTU) and superior reverse leakage performance (10 µA versus 1 mA). Pin-to-pin compatibility is maintained in the TO-220-3 package.

Q: What are the differences between the two substitute parts?

A: The STPS60H100CT and NTSV30H100CTG differ in product status, current rating, and reverse leakage characteristics. The STPS60H100CT is active product status with 30 A current rating and 10 µA reverse leakage. The NTSV30H100CTG is obsolete product status with 15 A current rating and 95 µA reverse leakage. Both maintain 100 V reverse voltage and TO-220-3 package compatibility. The STPS60H100CT offers superior performance and longer-term availability.

Q: Are there temperature range considerations when substituting?

A: The MBR30100CTU operates from -55°C to 150°C. The STPS60H100CT maximum junction temperature is 175°C, providing extended high-temperature capability. The NTSV30H100CTG operates from -40°C to 150°C, which is narrower at the low-temperature end. For applications requiring operation below -40°C, the MBR30100CTU or STPS60H100CT are required.

Q: Do all three parts have the same RoHS and moisture sensitivity compliance?

A: Yes. All three parts (MBR30100CTU, STPS60H100CT, and NTSV30H100CTG) are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are identical across all three components.

Q: What is the significance of the reverse leakage current differences?

A: Reverse leakage current affects power dissipation and circuit performance at high temperatures. The MBR30100CTU has 1 mA reverse leakage at 100 V. The STPS60H100CT has 10 µA, and the NTSV30H100CTG has 95 µA. Lower reverse leakage reduces standby power consumption and heat generation. The STPS60H100CT provides the best performance in this parameter.

Q: Is the TO-220-3 package identical across all three parts?

A: Yes. All three components use the TO-220-3 through-hole package. Pin configuration and mechanical dimensions are identical, enabling direct PCB footprint compatibility without layout modifications.

Q: Why is NTSV30H100CTG marked as obsolete?

A: The NTSV30H100CTG is designated as obsolete product status by onsemi, indicating the manufacturer has discontinued active production and support. While inventory is currently available (2200 units), long-term supply cannot be guaranteed. For new designs, active product alternatives such as STPS60H100CT are preferred.
