Package / Case: TO-220-3 Full Pack, Isolated Tab
Mounting Type: Through Hole

Current Rating Considerations: The MBRF25100CT operates at 25 A average rectified current per diode. Substitute parts are grouped by current rating capability. Parts with lower current ratings (5 A, 10 A, 15 A, 20 A) are suitable for applications where the full 25 A capacity is not required. Parts with equal or higher current ratings provide direct replacement capability.

Electrical Performance Parameters: Forward voltage (Vf), reverse leakage current, and operating temperature range vary among substitute parts. These parameters must be evaluated against specific application requirements to ensure functional compatibility.

Product Status: The MBRF25100CT is discontinued. All listed substitute parts maintain active product status with current manufacturer support and availability.

Engineering Selection Recommendations

For Direct Replacement (25 A Requirement): No active substitute part with 25 A current rating is available in the provided list. Applications requiring the full 25 A capacity must evaluate alternative sourcing or design modification.

For Reduced Current Applications (≤ 20 A): The VF40100C-E3/4W and VF40100C-M3/4W provide 20 A capability with lower forward voltage (730 mV @ 20 A) compared to the MBRF25100CT. Both parts are ROHS3 compliant and maintain active product status. VF40100C-M3/4W includes specified operating temperature range (-40°C ~ 150°C).

For Reduced Current Applications (≤ 15 A): The MBRF30H100CT-E3/45 and VF30100C-E3/4W provide 15 A capability. MBRF30H100CT-E3/45 offers extended operating temperature range (-65°C ~ 175°C) and lower reverse leakage (5 µA @ 100 V). VF30100C-E3/4W operates at -40°C ~ 150°C with higher reverse leakage (500 µA @ 100 V).

For Reduced Current Applications (≤ 10 A): Multiple options exist: MBRF20100CT-E3/4W, MBRF20H100CT-E3/45, VF20100C-E3/4W, and VF20100R-E3/4W. MBRF20H100CT-E3/45 provides superior reverse leakage performance (4.5 µA @ 100 V) and extended temperature range (-65°C ~ 175°C).

For Reduced Current Applications (≤ 5 A): MBRF10100CT-E3/4W and MF10H100CTHE3_B/P are available. MF10H100CTHE3_B/P includes AEC-Q101 automotive qualification and extended temperature range (-65°C ~ 175°C).

Compliance Considerations: All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the regulatory status of the MBRF25100CT.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower current rating than the MBRF25100CT?

A: Yes, if your application does not require the full 25 A capacity. Verify that the substitute part's current rating meets or exceeds your actual circuit requirements. Lower-rated parts are electrically compatible when current demand is within their specifications.

Q: What is the difference between MBRF and VF series parts?

A: Both series are Schottky diode arrays with identical package and configuration. The primary differences are in forward voltage, reverse leakage current, and operating temperature range. Consult the parameter comparison table to select based on your application's thermal and electrical requirements.

Q: Are all substitute parts pin-compatible with the MBRF25100CT?

A: Yes. All listed substitute parts use the TO-220-3 Full Pack with isolated tab package and maintain the same 1 pair common cathode configuration. Physical and electrical pin compatibility is maintained.

Q: Which substitute part has the lowest forward voltage drop?

A: VF40100C-E3/4W and VF40100C-M3/4W both provide 730 mV @ 20 A, the lowest forward voltage among the listed substitutes.

Q: Which substitute part has the lowest reverse leakage current?

A: MBRF20H100CT-E3/45 and MF10H100CTHE3_B/P provide the lowest reverse leakage at 4.5 µA and 3.5 µA @ 100 V respectively.

Q: Does the MF10H100CTHE3_B/P have automotive qualification?

A: Yes. MF10H100CTHE3_B/P is qualified to AEC-Q101 automotive standard and is suitable for automotive applications.
