MBRF1045 Equivalent & Substitute Parts

Part Overview

The MBRF1045 is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for high-speed switching applications requiring fast recovery characteristics. This through-hole component operates at a maximum reverse voltage of 45 V with an average rectified current rating of 10 A, making it suitable for power supply and rectification circuits. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Identification of equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain performance specifications across production batches and procurement cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectifier diodes is determined by electrical and mechanical parameter alignment within the Schottky diode category. The critical parameters governing substitution eligibility are:

Electrical Parameters:

• Maximum reverse voltage (Vr) must equal or exceed 45 V
• Average rectified current (Io) must equal or exceed 10 A
• Forward voltage drop (Vf) at rated current must not exceed 700 mV @ 10 A
• Reverse leakage current must not exceed 100 µA @ 45 V
• Recovery speed classification must maintain Fast Recovery characteristics (≤ 500ns, > 200mA)

Mechanical Parameters:

• Mounting type must be Through Hole
• Package designation must be TO-220-2 Full Pack or ITO-220AC equivalent
• Operating temperature range must encompass -55°C to 150°C junction temperature

Compliance Parameters:

• RoHS3 compliance status
• REACH unaffected designation
• Moisture Sensitivity Level 1 classification

Parts meeting all specified electrical, mechanical, and compliance criteria are classified as direct substitutes for the MBRF1045.

Parameter Comparison

Engineering Selection Recommendations

The MBRF1045 is an Active product with full regulatory compliance certifications. Selection of substitute components must maintain identical electrical specifications across reverse voltage, forward voltage, current ratings, and recovery speed characteristics. The through-hole TO-220-2 package format and ITO-220AC supplier designation establish mechanical compatibility requirements that must be preserved in any substitution scenario.

RoHS3 compliance and REACH unaffected status are mandatory for applications subject to environmental and regulatory restrictions. The Moisture Sensitivity Level 1 classification indicates unlimited shelf life without special storage requirements, a characteristic that should be maintained in substitute part selection.

Component selection should prioritize parts from the same manufacturer series (MBRF104 base product number) to ensure consistency in manufacturing process control and performance characteristics. Active product status confirms ongoing availability and manufacturing support, reducing supply chain risk.

Frequently Asked Questions (FAQ)

Q: What defines an acceptable substitute for the MBRF1045 Schottky diode?

A: An acceptable substitute must match all specified electrical parameters: 45 V maximum reverse voltage, 10 A average rectified current, 700 mV maximum forward voltage at 10 A, fast recovery speed (≤ 500ns), and 100 µA maximum reverse leakage current at 45 V. The substitute must also maintain identical mechanical specifications (through-hole mounting, TO-220-2 package, ITO-220AC supplier designation) and compliance certifications (RoHS3, REACH unaffected, MSL 1).

Q: Can the MBRF1045 be replaced with a diode having higher voltage or current ratings?

A: Higher voltage or current ratings do not automatically qualify a component as a substitute. The substitute must match the specified electrical parameters exactly. Components with different ratings may introduce design incompatibilities, altered thermal characteristics, or unintended circuit behavior. Substitution requires parameter equivalence, not parameter superiority.

Q: What is the significance of the ITO-220AC package designation?

A: The ITO-220AC designation specifies the supplier device package format, which defines the physical footprint, lead configuration, and thermal characteristics of the component. This designation must match exactly to ensure mechanical compatibility with printed circuit board layouts and thermal management designs. Deviations in package designation indicate incompatible physical or thermal properties.

Q: Does RoHS3 compliance affect substitution eligibility?

A: RoHS3 compliance is a mandatory requirement for substitution in applications subject to environmental regulations. Both the main part and substitute must maintain identical RoHS3 compliance status. Substitution with non-compliant components violates regulatory requirements and is not permissible in regulated applications.

Q: What role does the Moisture Sensitivity Level (MSL) play in component substitution?

A: MSL 1 classification indicates unlimited shelf life without special moisture control requirements. Substitutes must maintain MSL 1 status to preserve storage and handling procedures. Components with higher MSL ratings require controlled storage environments and may introduce supply chain complexity.

Q: Is the MBRF1045 available as an active product?

A: Yes, the MBRF1045 maintains Active product status, confirming ongoing manufacturing support and availability. Active status ensures continued supply chain access and manufacturing consistency for long-term production requirements.
