Equivalent & Substitute Parts for MBRF30045

Part Overview

MBRF30045 by GeneSiC Semiconductor is a Schottky diode array in a TO-244AB package, designed for high-current rectification with fast recovery. The configuration is 1 pair common cathode with a maximum DC reverse voltage of 45 V and a rectified average current of 150A per diode. The product status is obsolete, making it necessary to identify alternative models with comparable electrical and mechanical characteristics in the Diodes, Rectifiers product category.

Substitute Part Grouping Explanation

Substitute parts for MBRF30045 are determined strictly by matching the following key parameters: diode configuration (1 pair common cathode), Schottky technology, maximum DC reverse voltage (45 V), average rectified current per diode, mechanical package (TO-244AB), mounting type (chassis mount), and fast recovery speed. Only parts meeting these criteria within the Diodes, Rectifiers component category are listed as substitutes.

Engineering Selection Recommendations

Selection of substitute parts should be based on product status to ensure ongoing procurement. Both MBRF30045 and 301CNQ045 are obsolete. MBRF30045 has no provided compliance certifications, while 301CNQ045 is ROHS3 compliant and REACH unaffected. Use only substitute models meeting specified regulatory and compliance standards for the intended application, according to available documentation.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a diode or rectifier substitute in this application?
A1: Substitute selection requires matching diode configuration, technology type, maximum DC reverse voltage, current rating, mechanical package, mounting type, and operational recovery speed.

Q2: Are the mounting types and package codes identical for these substitutes?
A2: Yes. Both parts use chassis mount with TO-244AB package and supplier device package.

Q3: Do substituting parts need to have the same current rating?
A3: Substitute parts must meet or exceed the required average rectified current for the application, as provided.

Q4: What compliance or certification differences exist between the substitute parts?
A4: 301CNQ045 is ROHS3 compliant and REACH unaffected; no compliance status is given for MBRF30045.

Q5: Can obsolete parts be used in new designs?
A5: Product status should be considered for new designs. Obsolete parts may impact long-term availability and support.

Q6: Do these substitutes maintain compatibility in diode configuration and performance speed?
A6: Yes, both models specify 1 pair common cathode configuration and fast recovery performance under the defined operating conditions.
