Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF30H100CTG is determined by strict equivalence in the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory match)
• Technology: Schottky (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 100 V (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Package / Case: TO-220-3 Full Pack (mandatory match)

Secondary Compatibility Parameters:

• Current - Average Rectified (Io) (per Diode): Substitute must support minimum 15 A
• Voltage - Forward (Vf) (Max) @ If: Substitute must not exceed 800 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (mandatory match)
• RoHS Status: ROHS3 Compliant (mandatory match)
• Product Status: Active (mandatory match)

Substitute parts MBRF30100CT and MBRF30100CTP meet the primary substitution criteria. Both devices maintain the same diode configuration, Schottky technology, 100 V reverse voltage rating, through-hole mounting, and TO-220-3 Full Pack packaging. Both are ROHS3 compliant and active products.

Engineering Selection Recommendations

MBRF30100CT (Taiwan Semiconductor Corporation)

This substitute part is ROHS3 compliant and maintains active product status. It satisfies all primary substitution criteria: 1 Pair Common Cathode configuration, Schottky technology, 100 V reverse voltage, through-hole mounting, and TO-220-3 Full Pack packaging with isolated tab. The device supports 30 A average rectified current per diode, exceeding the 15 A requirement of the main part. Forward voltage is specified at 940 mV @ 30 A. Reverse leakage current is 200 µA @ 100 V. Operating temperature range is −55°C to 150°C.

MBRF30100CTP (SMC Diode Solutions)

This substitute part is ROHS3 compliant and maintains active product status. It satisfies all primary substitution criteria: 1 Pair Common Cathode configuration, Schottky technology, 100 V reverse voltage, through-hole mounting, and TO-220-3 Full Pack packaging with isolated tab. Forward voltage is specified at 850 mV @ 15 A, which is within the 800 mV maximum at 15 A. Reverse leakage current is 1 mA @ 100 V. Operating temperature range is −55°C to 150°C. Average rectified current per diode is not specified in the provided data.

Both substitute parts are suitable for direct replacement in applications where the MBRF30H100CTG is specified, provided that the differences in reverse leakage current and operating temperature range are acceptable for the intended circuit design.

Frequently Asked Questions (FAQ)

Q: Can MBRF30100CT be used as a direct replacement for MBRF30H100CTG?

A: Yes. Both devices share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, through-hole mounting, and TO-220-3 Full Pack packaging. Both are ROHS3 compliant and active products. The MBRF30100CT supports 30 A average rectified current, which exceeds the 15 A requirement of the MBRF30H100CTG.

Q: Can MBRF30100CTP be used as a direct replacement for MBRF30H100CTG?

A: Yes. Both devices share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, through-hole mounting, and TO-220-3 Full Pack packaging. Both are ROHS3 compliant and active products. Forward voltage of MBRF30100CTP is 850 mV @ 15 A, which is within the 800 mV maximum specification of the main part.

Q: What is the difference between TO-220FP and ITO-220AB packaging?

A: TO-220FP is a standard TO-220-3 Full Pack configuration. ITO-220AB is a TO-220-3 Full Pack with an isolated tab. Both are through-hole packages with the same pin configuration and footprint compatibility. The isolated tab in ITO-220AB provides electrical isolation between the tab and the mounting surface, which may be required in certain thermal management applications.

Q: Are there differences in reverse leakage current between the main part and substitutes?

A: Yes. The MBRF30H100CTG specifies 4.5 µA @ 100 V reverse leakage. The MBRF30100CT specifies 200 µA @ 100 V, and the MBRF30100CTP specifies 1 mA @ 100 V. These differences must be evaluated against circuit requirements, particularly in applications sensitive to leakage current.

Q: What is the operating temperature range difference?

A: The MBRF30H100CTG specifies a maximum junction temperature of 175°C. The MBRF30100CT and MBRF30100CTP both specify an operating temperature range of −55°C to 150°C. The lower maximum junction temperature of the substitute parts must be considered in thermal design.

Q: Are all three parts RoHS compliant?

A: Yes. The MBRF30H100CTG, MBRF30100CT, and MBRF30100CTP are all ROHS3 compliant.

Q: What is the significance of the isolated tab in ITO-220AB?

A: The isolated tab provides electrical isolation between the device tab and the mounting surface. This is useful in applications where the tab must be isolated from ground or other circuit potentials for thermal management without creating unintended electrical connections.
