DSTF30100C Equivalent & Substitute Parts

Part Overview

The DSTF30100C is a Schottky diode array manufactured by Littelfuse Inc., configured as a 1 Pair Common Cathode arrangement with a maximum reverse voltage rating of 100 V and average rectified current of 15 A per diode. This component is packaged in a TO-220-3 Full Pack with isolated tab configuration for through-hole mounting applications. The part is currently in active product status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the DSTF30100C is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Voltage - Forward (Vf) (Max) @ If: 750 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match or Exceed):

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

The substitute part SDT30100CTFP meets all mandatory electrical and mechanical parameters. Variations in reverse leakage current and maximum junction operating temperature represent acceptable parameter ranges within the Schottky diode array category and do not preclude substitution when the core electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: DSTF30100C (Littelfuse Inc.)

The DSTF30100C is the specified component and remains the first choice when available. It is an active product with full RoHS3 compliance and unlimited moisture sensitivity level. Current inventory status shows 1160 pieces in stock.

Substitute Part: SDT30100CTFP (Diodes Incorporated)

The SDT30100CTFP is a parametric equivalent that satisfies all mandatory electrical and mechanical specifications. This part is also an active product with RoHS3 compliance and unlimited MSL rating. The substitute demonstrates superior performance characteristics in two areas: reverse leakage current is reduced to 100 µA (compared to 500 µA in the primary part), and maximum junction operating temperature extends to 150°C (compared to 100°C in the primary part). These differences represent performance enhancements rather than deviations. Inventory availability is significantly higher at 28300 pieces in stock. The SDT30100CTFP is suitable for direct substitution in applications where the DSTF30100C is specified, provided that the TO-220-3 Full Pack isolated tab package and through-hole mounting configuration are compatible with the circuit board design.

Frequently Asked Questions (FAQ)

Q: Can SDT30100CTFP be used as a direct replacement for DSTF30100C?

A: Yes. The SDT30100CTFP meets all mandatory electrical parameters (100 V reverse voltage, 15 A average rectified current, 750 mV forward voltage, fast recovery Schottky technology) and mechanical parameters (TO-220-3 Full Pack isolated tab, through-hole mounting). Both parts are RoHS3 compliant with MSL 1 rating.

Q: What are the differences between DSTF30100C and SDT30100CTFP?

A: The parts are electrically and mechanically equivalent. Differences exist in reverse leakage current (500 µA vs. 100 µA at 100 V) and maximum junction operating temperature (-55 to 100°C vs. -55 to 150°C). The SDT30100CTFP exhibits lower leakage and extended temperature range, both favorable characteristics for most applications.

Q: Are there any package compatibility concerns?

A: No. Both parts use identical TO-220-3 Full Pack with isolated tab packaging. Pin configuration, lead spacing, and mounting hole dimensions are identical. No circuit board redesign is required.

Q: What is the significance of the isolated tab feature?

A: The isolated tab in the TO-220-3 Full Pack configuration provides electrical isolation between the tab and the semiconductor die, allowing the tab to be mounted to a heat sink without requiring an insulating washer or thermal interface material for electrical isolation. This feature is identical in both the primary and substitute parts.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The SDT30100CTFP is rated to 150°C junction temperature, while the DSTF30100C is rated to 100°C. For applications requiring operation above 100°C, the SDT30100CTFP is the appropriate selection. For applications operating within the -55 to 100°C range, both parts are suitable.

Q: What compliance certifications apply to both parts?

A: Both DSTF30100C and SDT30100CTFP are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry HTSUS code 8541.10.0080. Moisture sensitivity level is 1 (unlimited) for both parts.
