MBRF1045 C0G Schottky Diode Equivalent & Substitute Parts

Part Overview

The MBRF1045 C0G is a through-hole Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 45 V DC reverse voltage and 10 A average rectified current. This component is packaged in the TO-220-2 Full Pack (ITO-220AC) configuration and is designed for fast recovery applications with switching speeds ≤ 500 ns.

The original MBRF1045 C0G has been discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and redesign applications. Substitute parts must maintain identical electrical performance and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitution of the MBRF1045 C0G is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io): 10 A
• Voltage - Forward (Vf) (Max) @ If: 700 mV @ 10 A
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 45 V

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack
• Supplier Device Package: ITO-220AC

Environmental & Compliance Parameters:

• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: Direct Manufacturer Equivalents and Parametric Equivalents. Direct equivalents share identical part numbers and specifications. Parametric equivalents maintain all electrical and mechanical specifications but may include additional qualifications or certifications.

Parameter Comparison

Engineering Selection Recommendations

MBRF1045 (Direct Equivalent): This part is the direct manufacturer equivalent to the MBRF1045 C0G. It maintains active product status with 5991 pieces in stock, ensuring immediate availability. All electrical and mechanical parameters are identical. This part is the primary substitute for applications requiring direct replacement without additional qualifications.

MBRF1045HC0G (Parametric Equivalent): This part maintains complete electrical and mechanical equivalence to the MBRF1045 C0G while adding automotive-grade qualification (AEC-Q101). It is suitable for applications requiring automotive-grade components or enhanced reliability certifications. Product status is active with 1103 pieces in stock. Selection of this part is appropriate when automotive compliance or AEC-Q101 qualification is specified in the design requirements.

Both substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original part. The choice between direct and parametric equivalents depends on application-specific requirements for automotive qualification and certification.

Frequently Asked Questions (FAQ)

Q: Can MBRF1045 be used as a direct replacement for MBRF1045 C0G?

A: Yes. MBRF1045 is a direct manufacturer equivalent with identical electrical specifications (45 V, 10 A, 700 mV forward voltage, fast recovery ≤ 500 ns) and mechanical packaging (TO-220-2 Full Pack, ITO-220AC). The primary difference is product status: MBRF1045 is active with higher inventory availability, while MBRF1045 C0G is discontinued.

Q: What is the difference between MBRF1045 and MBRF1045HC0G?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. MBRF1045HC0G includes automotive-grade qualification (AEC-Q101) and is designated as an automotive-grade component. Selection depends on whether automotive qualification is required for the application.

Q: Are all substitute parts compatible with the original TO-220-2 Full Pack footprint?

A: Yes. All substitute parts use the TO-220-2 Full Pack (ITO-220AC) package configuration, ensuring mechanical and thermal compatibility with the original design without PCB modifications.

Q: Do the substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical junction temperature range of -55°C to 150°C, ensuring thermal performance equivalence.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance with the original MBRF1045 C0G.

Q: What is the reverse leakage current specification for the substitute parts?

A: All substitute parts maintain a reverse leakage current of 100 µA at 45 V, identical to the original part.

Q: Can MBRF1045HC0G be used in non-automotive applications?

A: Yes. MBRF1045HC0G meets all electrical and mechanical requirements for general-purpose applications. The automotive-grade qualification (AEC-Q101) is an additional certification that does not restrict use in non-automotive designs.
