Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1035-E3/45 is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the TO-263-3, D2PAK (2 Leads + Tab), TO-263AB surface mount package to ensure mechanical and thermal interface compatibility with existing PCB layouts.

Technology Class: Schottky diode technology is required to maintain fast recovery characteristics (≤ 500ns, > 200mA) and low forward voltage drop performance inherent to the original design.

Voltage Rating: The substitute part must support a minimum DC reverse voltage rating equal to or exceeding the 35 V maximum specification of the original component.

Current Rating: The substitute part must support a minimum average rectified current rating equal to or exceeding the 10 A specification of the original component.

Compliance Standards: The substitute part must maintain ROHS3 compliance and MSL 1 rating to satisfy regulatory and manufacturing requirements.

The identified substitute STPS10H100CG-TR from STMicroelectronics meets these substitution criteria while offering enhanced voltage rating (100 V) and active product status.

Voltage Margin: The STPS10H100CG-TR provides 100 V reverse voltage rating, exceeding the 35 V requirement of the original component, offering enhanced overvoltage protection margin.

Compliance Continuity: Both components maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, satisfying regulatory and manufacturing process requirements without modification.

Product Status: The STPS10H100CG-TR maintains active product status with confirmed inventory availability (4960 Pcs), ensuring long-term supply continuity and technical support access.

Current Rating Consideration: The STPS10H100CG-TR is configured as a diode array with 1 Pair Common Cathode topology, rated at 5 A per diode. Circuit design verification is required to confirm compatibility with the original 10 A single diode configuration.

Frequently Asked Questions (FAQ)

Q: Can the STPS10H100CG-TR directly replace the MBRB1035-E3/45 in existing designs?

A: The STPS10H100CG-TR shares identical package geometry (TO-263AB D2PAK) and mounting type (surface mount), enabling direct PCB footprint compatibility. However, the STPS10H100CG-TR is a diode array with 1 Pair Common Cathode configuration rated at 5 A per diode, whereas the MBRB1035-E3/45 is a single diode rated at 10 A. Circuit topology verification is required to confirm functional compatibility with the original design.

Q: What are the key differences in electrical performance between these components?

A: The STPS10H100CG-TR provides higher reverse voltage rating (100 V vs. 35 V), lower forward voltage drop (730 mV @ 5 A vs. 840 mV @ 20 A), and significantly lower reverse leakage current (3.5 µA @ 100 V vs. 100 µA @ 35 V). Both components maintain identical fast recovery speed specifications (≤ 500ns, > 200mA).

Q: Are there compliance or regulatory differences between these parts?

A: Both components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. No compliance differences exist between the two parts.

Q: What is the significance of the diode array configuration in the STPS10H100CG-TR?

A: The STPS10H100CG-TR contains two Schottky diodes in a common cathode configuration within a single TO-263AB package. This configuration requires circuit design verification to confirm compatibility with applications originally designed for a single 10 A diode topology.

Q: How does the higher voltage rating of the STPS10H100CG-TR affect circuit design?

A: The 100 V reverse voltage rating of the STPS10H100CG-TR exceeds the 35 V requirement of the original component. This provides additional overvoltage protection margin and may improve reliability in circuits subject to transient voltage spikes. No circuit modifications are required due to the higher voltage rating.

Q: Is the STPS10H100CG-TR suitable for high-temperature applications?

A: The STPS10H100CG-TR supports maximum junction temperature of 175°C, compared to the MBRB1035-E3/45 maximum of 150°C. This provides 25°C additional thermal margin for high-temperature operating environments.
