Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR20150CTP is determined by the following critical parameters that must remain constant or be compatible with the original design:

Fixed Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Isolated Tab

Variable Parameters (Allowable Substitution Range):

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 10A
• Voltage - Forward (Vf) (Max) @ If: Equal to or less than 900 mV @ 10 A
• Current - Reverse Leakage @ Vr: Equal to or less than 100 µA @ 150 V
• Operating Temperature - Junction: Must encompass or exceed -65°C ~ 175°C range

Substitute parts meeting these criteria are electrically compatible and mechanically interchangeable with the MBR20150CTP in through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MBRF20150CT

MBRF20150CT is the preferred substitute for MBR20150CTP applications. This part maintains electrical equivalence with 150V reverse voltage and 20A current rating (exceeding the 10A requirement). The device is manufactured by Taiwan Semiconductor Corporation with Active product status, ensuring long-term availability. ROHS3 compliance and MSL 1 rating match the original specification. Operating temperature range of -55°C to 150°C covers the majority of industrial applications, though it does not extend to the original -65°C lower limit.

Secondary Recommendation: MBRF20H150CTG

MBRF20H150CTG is manufactured by onsemi under the SWITCHMODE™ series and provides electrical compatibility with 150V reverse voltage and 10A current rating matching the original specification. The device carries Last Time Buy status, indicating limited future availability. This option is suitable for immediate replacement but should not be selected for new long-term designs. ROHS3 compliance is confirmed. Forward voltage of 680 mV @ 10A is superior to the original 900 mV specification.

Alternative for Higher Current Applications: MBRF30150CT

MBRF30150CT provides 30A current rating with 150V reverse voltage, suitable for designs requiring higher current capacity than the original 10A specification. Manufactured by Taiwan Semiconductor Corporation with Active product status. ROHS3 compliant with MSL 1 rating. Operating temperature range of -55°C to 150°C is consistent with other active alternatives.

Not Recommended: MBR20150FCT-BP

MBR20150FCT-BP is manufactured by Micro Commercial Co with Active product status and 20A current rating. However, the operating temperature specification lists only 150°C maximum without a minimum temperature range, creating uncertainty for applications requiring extended low-temperature operation. This part should be avoided unless specific application requirements confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can MBR20150CTP be directly replaced with MBRF20150CT?

A: Yes. MBRF20150CT is electrically and mechanically compatible. Both devices share identical 150V reverse voltage rating, 1 Pair Common Cathode configuration, and TO-220-3 Isolated Tab package. The 20A current rating of MBRF20150CT exceeds the 10A requirement of MBR20150CTP, providing design margin. ROHS3 compliance and MSL 1 rating are equivalent.

Q: What is the difference between TO-220-3 Isolated Tab and TO-220-3 Full Pack?

A: Both are TO-220-3 through-hole packages with identical pin configuration and PCB footprint. The Isolated Tab variant provides electrical isolation between the tab and the die, while Full Pack does not. For applications where the tab is used as a heat sink connection, verify that the circuit design accommodates the electrical isolation difference. Mechanical mounting is identical.

Q: Why does MBR20150FCT-BP show only 150°C maximum temperature without a minimum?

A: The provided specification for MBR20150FCT-BP lists only the maximum junction temperature of 150°C without defining the minimum operating temperature. This incomplete specification creates ambiguity for applications requiring operation below 0°C. MBRF20150CT and MBRF30150CT provide complete temperature ranges (-55°C to 150°C), making them more suitable for temperature-critical applications.

Q: Is MBRF20H150CTG suitable for new designs?

A: MBRF20H150CTG carries Last Time Buy status, indicating that onsemi has announced end-of-life for this product. While currently available in inventory (2106 units), this part should not be selected for new long-term designs. MBRF20150CT or MBRF30150CT are preferred for designs requiring extended product lifecycle support.

Q: What is the significance of the 10A versus 20A versus 30A current ratings?

A: The MBR20150CTP is rated for 10A average rectified current per diode. Substitute parts with 20A or 30A ratings provide higher current capacity and are electrically compatible for applications requiring the original 10A specification. Higher-rated devices typically exhibit lower forward voltage drop and reduced reverse leakage current, improving overall circuit efficiency. Selection of a higher-rated device does not degrade performance in 10A applications.

Q: Are all substitute parts ROHS3 compliant?

A: MBRF20150CT, MBRF20H150CTG, and MBRF30150CT are confirmed ROHS3 compliant. MBR20150FCT-BP does not specify RoHS status in the provided data. For applications requiring ROHS3 compliance certification, MBRF20150CT is the recommended choice.

Q: Can MBR20150CTP be used in applications rated for 30A?

A: No. The MBR20150CTP is rated for maximum 10A average rectified current per diode. Using this device in 30A applications exceeds its electrical rating and creates reliability risk. MBRF30150CT is the appropriate choice for 30A applications.

Q: What is the impact of forward voltage differences between substitute parts?

A: Forward voltage affects power dissipation and heat generation. MBR20150CTP specifies 900 mV @ 10A, while MBRF20H150CTG specifies 680 mV @ 10A. Lower forward voltage reduces power loss and heat dissipation. MBRF20150CT and MBRF30150CT specify 1.05V at their respective rated currents (20A and 30A). When operating at 10A, these higher-rated devices may exhibit lower forward voltage than specified. Circuit thermal design should account for these differences.
