MBRF1645 C0G Equivalent & Substitute Parts

Part Overview

The MBRF1645 C0G is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole applications in the TO-220-2 package. This component operates at a maximum reverse voltage of 45 V with an average rectified current rating of 16 A, making it suitable for power conversion and rectification circuits requiring fast recovery characteristics.

The MBRF1645 C0G variant is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure uninterrupted supply for production and repair applications. The active MBRF1645 variant remains available as a direct functional equivalent.

Substitute Part Grouping Explanation

Substitution of the MBRF1645 C0G is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 45 V
• Current - Average Rectified (Io): 16 A
• Voltage - Forward (Vf) (Max) @ If: 630 mV @ 16 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 500 µA @ 45 V
• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky

Parts are classified as direct substitutes only when all electrical ratings and mechanical specifications match exactly. No parameter deviation is permitted for functional equivalence in rectifier diode applications.

Engineering Selection Recommendations

The MBRF1645 (active variant) is the direct functional equivalent to the MBRF1645 C0G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Basis:

The active MBRF1645 variant is recommended for new procurement and replacement applications. This part maintains full electrical and thermal equivalence with the discontinued MBRF1645 C0G while offering the advantage of active product status and confirmed inventory availability.

Both variants comply with ROHS3 and REACH requirements, carry MSL Level 1 (Unlimited) moisture sensitivity classification, and are subject to EAR99 export control classification. The operating temperature range of -55°C to 150°C junction temperature is identical across both variants.

No alternative manufacturers or part numbers provide equivalent specifications within the provided parameter set. Selection of the active MBRF1645 ensures design continuity and maintains all circuit performance characteristics of the original discontinued component.

Frequently Asked Questions (FAQ)

Q: Can the MBRF1645 (active) be used as a direct replacement for the MBRF1645 C0G?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation and possess identical electrical ratings, thermal specifications, and mechanical packaging. The active variant is the direct functional equivalent.

Q: What are the critical electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by exact matching of: reverse voltage rating (45 V), average rectified current (16 A), forward voltage drop (630 mV @ 16 A), recovery speed (Fast Recovery ≤ 500ns), reverse leakage current (500 µA @ 45 V), and operating temperature range (-55°C to 150°C).

Q: Does the TO-220-2 package remain unchanged between the discontinued and active variants?

A: Yes. Both the MBRF1645 C0G and MBRF1645 are packaged in TO-220-2 Full Pack configuration with through-hole mounting. PCB layout and thermal management considerations remain identical.

Q: Are there compliance or certification differences between the two variants?

A: No. Both variants maintain ROHS3 compliance, REACH Unaffected status, MSL Level 1 (Unlimited) classification, and EAR99 export control designation.

Q: What is the primary reason for the MBRF1645 C0G discontinuation?

A: The MBRF1645 C0G is discontinued at DiGi Electronics. The active MBRF1645 variant remains in production and available for procurement.
