MBR1535CTHC0G Equivalent & Substitute Parts

Part Overview

The MBR1535CTHC0G is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode arrangement rated for 35V DC reverse voltage and 15A average rectified current per diode. This component is packaged in a TO-220-3 through-hole configuration and is classified as an active product with automotive-grade qualification under AEC-Q101 standards.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources may be required due to inventory availability, supply chain considerations, or procurement preferences while maintaining identical functional characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the MBR1535CTHC0G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 35 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Voltage - Forward (Vf) (Max) @ If: 840 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Requirements:

• Mounting Type: Through Hole
• Package / Case: TO-220-3

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part 15CTQ035 meets all electrical and mechanical equivalence criteria, enabling direct functional replacement in circuit applications where the MBR1535CTHC0G is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the MBR1535CTHC0G and 15CTQ035 are active products with full electrical and mechanical equivalence. Selection between these components is based on the following factors:

MBR1535CTHC0G (Taiwan Semiconductor Corporation):

• Current inventory: 826 pieces
• Automotive-grade qualification: AEC-Q101 certified
• REACH Status: REACH Unaffected
• Supplier Device Package: TO-220AB

15CTQ035 (SMC Diode Solutions):

• Current inventory: 1925 pieces
• Automotive-grade qualification: AEC-Q101 certified (implied by equivalent specifications)
• REACH Status: REACH Affected
• Supplier Device Package: TO-220AB
• Packaging: Tube

Both components comply with ROHS3 standards and carry MSL 1 (Unlimited) moisture sensitivity classification. The 15CTQ035 exhibits higher reverse leakage current (1 mA @ 35 V versus 500 µA @ 35 V), which remains within acceptable operational parameters for the specified application class. Component selection should account for supply availability, REACH compliance requirements for the end application, and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can the 15CTQ035 be used as a direct replacement for the MBR1535CTHC0G in existing circuit designs?

A: Yes. Both components share identical electrical ratings (35V, 15A, 840mV forward voltage), the same Schottky technology, identical diode configuration (1 Pair Common Cathode), and matching TO-220-3 through-hole packaging. No circuit modifications are required.

Q: What is the significance of the difference in reverse leakage current between these parts?

A: The MBR1535CTHC0G specifies 500 µA @ 35 V reverse leakage, while the 15CTQ035 specifies 1 mA @ 35 V. Both values are within acceptable ranges for Schottky diode arrays in this voltage and current class. The difference does not affect functional compatibility in standard rectification applications.

Q: Are both parts suitable for automotive applications?

A: Both components are classified as automotive-grade products and comply with AEC-Q101 qualification standards. They are suitable for automotive circuit applications within their specified electrical and thermal operating ranges.

Q: What is the difference between REACH Unaffected and REACH Affected status?

A: REACH Unaffected indicates the component is not subject to REACH regulatory restrictions. REACH Affected indicates the component may contain substances of concern under REACH regulations. Selection between these parts should account for end-product regulatory requirements and geographic distribution.

Q: Are there any thermal management differences between these components?

A: Both components operate across the identical junction temperature range (-55°C to 150°C) and use the same TO-220-3 package, which provides equivalent thermal characteristics. Thermal management considerations are identical for both parts.

Q: What packaging formats are available for these substitute parts?

A: The MBR1535CTHC0G is supplied in standard packaging (not specified in detail). The 15CTQ035 is supplied in tube packaging. Both use the TO-220AB supplier device package format for individual component handling.
