Key Parameters

Substitute Part Grouping Explanation

Substitution of the SBL2035CT is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (electrical pin compatibility)
• Technology: Schottky (switching characteristics and forward voltage behavior)
• Voltage - DC Reverse (Vr) (Max): 35 V (minimum voltage rating requirement)
• Current - Average Rectified (Io) (per Diode): 20 A (current handling capacity)
• Package / Case: TO-220-3 (mechanical and thermal interface)
• Mounting Type: Through Hole (PCB assembly compatibility)

Secondary Compatibility Parameters:

• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io) (switching performance)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (storage and handling requirements)

Substitute parts are grouped into two categories:

Category A - Direct Electrical Equivalents: Parts matching all primary substitution criteria with identical or superior electrical performance characteristics.

Category B - Functional Alternatives: Parts with reduced current or voltage ratings that may be suitable for applications with lower electrical demands but maintain the same package, configuration, and technology.

Parameter Comparison

Engineering Selection Recommendations

20CTQ035 (SMC Diode Solutions)

The 20CTQ035 is the primary direct equivalent for the SBL2035CT. Both parts share identical diode configuration (1 Pair Common Cathode), voltage rating (35 V), current rating (20 A), package (TO-220-3), and fast recovery switching characteristics. The 20CTQ035 maintains active product status and ROHS3 compliance. The primary difference is forward voltage specification at 800 mV @ 20 A compared to 550 mV @ 10 A for the SBL2035CT, and a minimum operating temperature of -55°C versus -65°C. This part is suitable for direct replacement in applications where the specified forward voltage and temperature range are acceptable.

MBR2035CT (Solid State Inc.)

The MBR2035CT matches the SBL2035CT in voltage rating (35 V), current rating (20 A), package (TO-220-3), and technology (Schottky). However, the diode configuration differs: MBR2035CT is configured as 2 Independent diodes rather than 1 Pair Common Cathode. This configuration difference affects pin compatibility and circuit topology. The MBR2035CT maintains active product status and ROHS3 compliance. Selection of this part requires verification of circuit pin compatibility with the 2 Independent configuration.

MBR1535CTG (onsemi)

The MBR1535CTG is a reduced-current alternative with 7.5 A per diode versus 20 A for the SBL2035CT. It maintains the 35 V voltage rating, 1 Pair Common Cathode configuration, TO-220-3 package, and Schottky technology. The MBR1535CTG offers an extended operating temperature range (-65°C ~ 175°C) and lower reverse leakage current (100 µA @ 35 V). This part is classified as obsolete. Selection is appropriate only for applications with current requirements not exceeding 7.5 A per diode.

MBR2030CTLG (onsemi)

The MBR2030CTLG is a reduced-voltage and reduced-current alternative with 30 V reverse voltage and 10 A per diode. It maintains the 1 Pair Common Cathode configuration, TO-220-3 package, and Schottky technology. The MBR2030CTLG is classified as Last Time Buy. Selection is appropriate only for applications with voltage requirements not exceeding 30 V and current requirements not exceeding 10 A per diode.

Frequently Asked Questions (FAQ)

Q: Can the 20CTQ035 be used as a direct replacement for the SBL2035CT?

A: The 20CTQ035 is electrically compatible with the SBL2035CT in terms of voltage rating (35 V), current rating (20 A), diode configuration (1 Pair Common Cathode), package (TO-220-3), and switching characteristics. The primary differences are forward voltage specification and minimum operating temperature. The 20CTQ035 is suitable for direct replacement where these parameter differences are acceptable for the application.

Q: What is the difference between the MBR2035CT and the SBL2035CT?

A: Both parts share the same voltage rating (35 V), current rating (20 A), and package (TO-220-3). The critical difference is diode configuration: the SBL2035CT is 1 Pair Common Cathode, while the MBR2035CT is 2 Independent. This configuration difference affects pin connectivity and circuit topology. The MBR2035CT cannot be used as a direct pin-for-pin replacement without circuit modification.

Q: Can the MBR1535CTG replace the SBL2035CT?

A: The MBR1535CTG shares the same voltage rating (35 V), diode configuration (1 Pair Common Cathode), package (TO-220-3), and technology (Schottky) as the SBL2035CT. However, the current rating is reduced to 7.5 A per diode compared to 20 A. The MBR1535CTG is suitable only for applications where the maximum current requirement does not exceed 7.5 A per diode.

Q: Is the MBR2030CTLG a suitable substitute for the SBL2035CT?

A: The MBR2030CTLG maintains the same diode configuration (1 Pair Common Cathode), package (TO-220-3), and technology (Schottky) as the SBL2035CT. However, both voltage and current ratings are reduced: 30 V versus 35 V, and 10 A versus 20 A per diode. The MBR2030CTLG is suitable only for applications with voltage requirements not exceeding 30 V and current requirements not exceeding 10 A per diode.

Q: What is the significance of the TO-220-3 package for substitution?

A: The TO-220-3 package is a through-hole configuration that determines mechanical fit, thermal interface, and PCB assembly compatibility. All substitute parts listed maintain the TO-220-3 package, ensuring mechanical and thermal compatibility with the original SBL2035CT. Package compatibility is a prerequisite for substitution.

Q: Why is the SBL2035CT classified as obsolete?

A: The SBL2035CT is listed as obsolete, indicating that the manufacturer has discontinued production. The substitute parts listed, particularly the 20CTQ035 (Active status) and MBR2035CT (Active status), provide continued availability for applications requiring equivalent electrical and mechanical specifications.

Q: What does "1 Pair Common Cathode" configuration mean?

A: The 1 Pair Common Cathode configuration indicates that the diode array contains two diodes with a shared cathode terminal. This configuration affects pin connectivity and is critical for circuit compatibility. Substitute parts must maintain this configuration for direct replacement without circuit modification.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed (20CTQ035, MBR2035CT, MBR1535CTG, and MBR2030CTLG) are ROHS3 compliant, matching the compliance status of the SBL2035CT. This ensures regulatory compliance for applications subject to RoHS requirements.
