MBRF3045CTP Equivalent & Substitute Parts

Part Overview

The MBRF3045CTP is a Schottky diode array manufactured by SMC Diode Solutions, configured as a 1 Pair Common Cathode arrangement in a TO-220-3 Full Pack with isolated tab. This component is designed for applications requiring fast recovery rectification at 45 V DC reverse voltage with through-hole mounting. The part is Active in product status and widely used in power conversion and switching applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the MBRF3045CTP are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a valid substitution:

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

The MBRF2545CT-E3/45 meets all these criteria and is therefore classified as an equivalent substitute. Variations in forward voltage characteristics, reverse leakage current, and operating temperature range do not preclude substitution when the core electrical and mechanical parameters remain constant.

Engineering Selection Recommendations

Both the MBRF3045CTP and MBRF2545CT-E3/45 are Active products with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for production environments with equivalent regulatory standing. The MBRF2545CT-E3/45 offers an extended lower operating temperature range (-65°C versus -55°C), which may provide additional thermal margin in applications requiring operation at lower junction temperatures. Both components maintain identical package geometry, mounting type, and fast recovery speed specifications, ensuring direct mechanical and electrical compatibility in circuit board layouts. Selection between these parts should be based on application-specific current and voltage requirements within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the MBRF2545CT-E3/45 be used as a direct replacement for the MBRF3045CTP?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), Schottky technology, 45 V DC reverse voltage rating, fast recovery speed, TO-220-3 Full Pack isolated tab package, and through-hole mounting. The parts are mechanically and electrically interchangeable.

Q: What are the differences between these two parts?

A: The MBRF2545CT-E3/45 specifies a 12.5 A average rectified current per diode, while the MBRF3045CTP does not specify this parameter. The MBRF2545CT-E3/45 exhibits higher forward voltage (820 mV @ 30 A versus 700 mV @ 15 A) and lower reverse leakage current (200 µA @ 45 V versus 1 mA @ 45 V). The MBRF2545CT-E3/45 operates at a lower minimum junction temperature (-65°C versus -55°C).

Q: Are there any package or pinout differences?

A: No. Both parts use the TO-220-3 Full Pack with isolated tab package configuration. Pinout and mechanical dimensions are identical, allowing for direct board-level substitution without layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MBRF3045CTP and MBRF2545CT-E3/45 are ROHS3 compliant with MSL rating of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Which part should be selected for applications requiring lower operating temperatures?

A: The MBRF2545CT-E3/45 supports operation down to -65°C junction temperature, compared to -55°C for the MBRF3045CTP. Applications requiring extended low-temperature performance should specify the MBRF2545CT-E3/45.

Q: Are there current rating considerations for substitution?

A: The MBRF2545CT-E3/45 specifies 12.5 A average rectified current per diode. Applications must verify that circuit current requirements do not exceed this rating. The MBRF3045CTP does not provide a specified average rectified current parameter.
