Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRF30L45CTHC0G are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Fixed Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 45 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Supplier Device Package: ITO-220AB
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Current - Average Rectified (Io) (per Diode): Substitute parts rated at 7.5 A and 12.5 A are acceptable for applications with lower current requirements
• Voltage - Forward (Vf) (Max) @ If: Varies with current rating
• Current - Reverse Leakage @ Vr: Varies with current rating
• Operating Temperature - Junction: Extended range acceptable
• Manufacturer: Alternative qualified manufacturers permitted

The identified substitute parts MBRF1545CT-E3/45 and MBRF2545CT-E3/45 maintain all fixed parameters while offering reduced current ratings suitable for lower-power applications within the same voltage class and package footprint.

Parameter Comparison

Engineering Selection Recommendations

MBRF30L45CTHC0G (Primary Part)

Selection is appropriate for applications requiring 30 A average rectified current per diode at 45 V reverse voltage. This part carries AEC-Q101 automotive qualification and maintains Active product status. The component is suitable for automotive-grade rectification circuits with high current demands.

MBRF2545CT-E3/45 (Substitute for Reduced Current Applications)

This part is suitable for applications requiring 12.5 A average rectified current per diode at 45 V reverse voltage. The MBRF2545CT-E3/45 maintains identical package configuration, voltage rating, and fast recovery speed characteristics. Both parts are ROHS3 compliant and Active. The extended operating temperature range (-65°C to 150°C) of the MBRF2545CT-E3/45 provides additional thermal margin compared to the primary part.

MBRF1545CT-E3/45 (Substitute for Lower Current Applications)

This part is suitable for applications requiring 7.5 A average rectified current per diode at 45 V reverse voltage. The MBRF1545CT-E3/45 maintains identical package configuration, voltage rating, and fast recovery speed characteristics. Both parts are ROHS3 compliant and Active. The extended operating temperature range (-65°C to 150°C) provides additional thermal margin.

All substitute parts maintain mechanical and electrical compatibility through identical TO-220-3 Full Pack isolated tab packaging and ITO-220AB supplier device package designation. Selection between primary and substitute parts depends solely on circuit current requirements and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can MBRF2545CT-E3/45 or MBRF1545CT-E3/45 be used as direct replacements for MBRF30L45CTHC0G?

A: Direct replacement is not applicable. The substitute parts have lower current ratings (12.5 A and 7.5 A respectively) compared to the primary part (30 A). Substitution is only valid for applications with current requirements within the substitute part's rating. The parts are mechanically and electrically compatible through identical package configuration and voltage rating.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching the following parameters: diode configuration (1 Pair Common Cathode), technology (Schottky), reverse voltage rating (45 V), fast recovery speed (≤ 500ns, > 200mA), and package type (TO-220-3 Full Pack, Isolated Tab, ITO-220AB). Current rating is the primary variable parameter that differs between the primary and substitute parts.

Q: Are all three parts suitable for automotive applications?

A: The MBRF30L45CTHC0G carries explicit AEC-Q101 automotive qualification and Automotive grade designation. The MBRF2545CT-E3/45 and MBRF1545CT-E3/45 are manufactured by Vishay General Semiconductor and maintain ROHS3 compliance and Active product status. Automotive suitability of substitute parts should be confirmed against specific application requirements and qualification documentation.

Q: What is the difference in forward voltage between these parts?

A: Forward voltage varies with current rating. The MBRF30L45CTHC0G exhibits 740 mV @ 30 A, the MBRF2545CT-E3/45 exhibits 820 mV @ 30 A, and the MBRF1545CT-E3/45 exhibits 570 mV @ 7.5 A. Forward voltage characteristics are current-dependent and should be evaluated within the specific operating current range of each application.

Q: Are there packaging differences between these parts?

A: All three parts use identical TO-220-3 Full Pack with isolated tab configuration and ITO-220AB supplier device package designation. Mechanical footprint and mounting characteristics are identical, allowing for direct physical substitution on printed circuit boards designed for TO-220-3 through-hole mounting.

Q: What is the reverse leakage current difference?

A: Reverse leakage current at 45 V is 400 µA for MBRF30L45CTHC0G, 200 µA for MBRF2545CT-E3/45, and 100 µA for MBRF1545CT-E3/45. Lower current-rated parts exhibit lower reverse leakage characteristics.

Q: Do the substitute parts have different temperature operating ranges?

A: The MBRF30L45CTHC0G operates from -55°C to 150°C junction temperature. Both substitute parts (MBRF2545CT-E3/45 and MBRF1545CT-E3/45) operate from -65°C to 150°C, providing an extended lower temperature range of 10°C additional margin.
