DSTF40150C Equivalent & Substitute Parts

Part Overview

The DSTF40150C is a Schottky diode array manufactured by Littelfuse Inc., configured as a 1 Pair Common Cathode rectifier with 150 V reverse voltage rating and 20 A average rectified current per diode. The component is packaged in a TO-220-3 Full Pack with isolated tab for through-hole mounting applications. This part is currently Active in product status and maintains full RoHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical packaging, and thermal operating ranges. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or inventory limitations while maintaining identical functional performance in the target application.

Substitute Part Grouping Explanation

Substitute parts for the DSTF40150C are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based strictly on the following matching criteria:

Electrical Parameters (Must Match Exactly):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io) (per Diode): 20 A
• Voltage - Forward (Vf) (Max) @ If: 1.43 V @ 20 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 250 µA @ 150 V
• Operating Temperature - Junction: -55°C ~ 150°C

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Through Hole
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Supplier Device Package: ITO-220AB

Compliance Parameters (Must Match Exactly):

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

All substitute parts listed below satisfy these criteria without exception and are therefore direct functional equivalents suitable for one-to-one replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed—DSTF40150C, VF40150C-E3/4W, and VF40150C-M3/4W—are Active products with full RoHS3 compliance and REACH Unaffected status. Each part maintains identical electrical specifications, mechanical packaging, and thermal operating ranges, confirming direct functional equivalence.

Selection Criteria Based on Availability:

The DSTF40150C (Littelfuse Inc.) maintains 929 pieces in current inventory. The VF40150C-E3/4W (Vishay TMBS® series) provides the highest inventory availability at 6400 pieces, making it the preferred substitute when supply of the primary part is constrained. The VF40150C-M3/4W (Vishay TMBS® series) maintains 1610 pieces in inventory and serves as a secondary substitute option.

All three parts are suitable for direct one-to-one replacement in applications requiring a 150 V, 20 A Schottky diode array with 1 Pair Common Cathode configuration in TO-220-3 Full Pack, Isolated Tab packaging. Selection between these equivalents should be based on procurement lead time, inventory availability, and supplier preference, as electrical and mechanical performance are identical across all options.

Frequently Asked Questions (FAQ)

Q: Can VF40150C-E3/4W or VF40150C-M3/4W be used as direct replacements for DSTF40150C?

A: Yes. Both Vishay parts are parametric equivalents with identical electrical specifications, mechanical packaging, and thermal operating ranges. They are suitable for direct one-to-one replacement in circuit applications without modification to PCB layout or design.

Q: What is the difference between VF40150C-E3/4W and VF40150C-M3/4W?

A: Both parts are from Vishay's TMBS® series and share identical electrical and mechanical specifications. The difference lies in packaging tape configuration (E3/4W versus M3/4W designations) and current inventory levels. Functionally, they are equivalent for circuit applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. DSTF40150C, VF40150C-E3/4W, and VF40150C-M3/4W are all ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the significance of the TO-220-3 Full Pack, Isolated Tab package?

A: This package designation indicates a three-lead through-hole component with an isolated mounting tab, allowing direct thermal coupling to a heatsink without electrical isolation requirements. All substitute parts use identical ITO-220AB supplier device packaging, ensuring mechanical compatibility with existing PCB designs.

Q: Can these parts operate across the full temperature range specified?

A: Yes. All three parts maintain operating junction temperature range of -55°C to 150°C, confirming suitability for applications across industrial, automotive, and consumer temperature environments.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Are there any electrical performance differences between the Littelfuse and Vishay options?

A: No. All three parts share identical forward voltage (1.43 V @ 20 A), reverse leakage current (250 µA @ 150 V), reverse voltage rating (150 V), and average rectified current (20 A per diode). Performance in circuit applications is equivalent.
