32CTQ030S Equivalent & Substitute Parts

Part Overview

The 32CTQ030S is a Schottky diode array manufactured by SMC Diode Solutions, configured as a 1 Pair Common Cathode design rated for 30 V DC reverse voltage and 15 A average rectified current per diode. The device is packaged in TO-263-3 (D2PAK) surface mount configuration with a tab connection. This component is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when alternative manufacturers offer diode arrays with identical electrical specifications, mechanical packaging, and performance characteristics. Substitution becomes necessary due to supply chain availability, inventory levels, or procurement preferences while maintaining full functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 32CTQ030S are identified based on strict parametric equivalence across the following critical specifications:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Voltage - Forward (Vf) (Max) @ If: 490 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Mounting Type: Surface Mount

Compliance Parameters:

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

Substitute parts may vary in packaging format (Tape & Reel, Tube, or Cut Tape), current reverse leakage specifications within acceptable ranges, and operating temperature maximum ratings, provided all primary electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—32CTQ030S, STPS3030CG-TR, VS-32CTQ030S-M3, and VS-32CTQ030STRL-M3—are functionally equivalent for applications requiring a 30 V, 15 A Schottky diode array in TO-263-3 (D2PAK) surface mount configuration. Each part maintains Active product status and ROHS3 compliance.

Selection Criteria Based on Provided Parameters:

SMC 32CTQ030S (Tape & Reel): Primary choice when Tape & Reel packaging is specified. Highest inventory availability (18,200 pcs). Reverse leakage of 1.75 mA @ 30 V. Operating temperature range -55°C to 150°C. REACH Affected status.

STMicroelectronics STPS3030CG-TR (Tape & Reel): Alternative when STMicroelectronics supply chain is preferred. Lower reverse leakage specification (1 mA @ 30 V). Operating temperature maximum of 150°C (no minimum specified). REACH Unaffected status. Lower inventory (1,594 pcs).

Vishay VS-32CTQ030S-M3 (Tube): Suitable when Tube packaging format is required. Reverse leakage of 1.75 mA @ 30 V. Operating temperature range -55°C to 150°C. REACH Unaffected status. High inventory availability (16,318 pcs).

Vishay VS-32CTQ030STRL-M3 (Cut Tape): Appropriate for Cut Tape packaging requirements. Reverse leakage of 1.75 mA @ 30 V. Operating temperature range -55°C to 150°C. REACH Unaffected status. Moderate inventory (8,054 pcs).

Selection between these parts should be based on packaging format requirements, supply chain preferences, and REACH compliance status for the end application.

Frequently Asked Questions (FAQ)

Q: Can STPS3030CG-TR replace 32CTQ030S in all applications?

A: STPS3030CG-TR is electrically equivalent to 32CTQ030S across all critical parameters: 30 V reverse voltage, 15 A average rectified current, 490 mV forward voltage at 15 A, and fast recovery Schottky technology. Both use identical TO-263-3 (D2PAK) surface mount packaging. The primary difference is packaging format (Tape & Reel for both) and reverse leakage specification (1 mA versus 1.75 mA @ 30 V). Direct substitution is supported for equivalent circuit performance.

Q: What is the difference between Tape & Reel, Tube, and Cut Tape packaging?

A: Packaging format affects handling and assembly processes but not electrical performance. Tape & Reel (TR) provides continuous strip packaging for automated pick-and-place assembly. Tube packaging contains individual components in a plastic tube for manual handling. Cut Tape (CT) provides components on tape segments cut to specified lengths. All three formats contain identical diode arrays with the same electrical specifications.

Q: Are the Vishay parts (VS-32CTQ030S-M3 and VS-32CTQ030STRL-M3) interchangeable?

A: VS-32CTQ030S-M3 and VS-32CTQ030STRL-M3 are electrically and mechanically identical. The difference is packaging format: VS-32CTQ030S-M3 is supplied in Tube format, while VS-32CTQ030STRL-M3 is supplied in Cut Tape format. Both contain the same diode array with identical electrical performance. Selection between them depends on assembly process requirements.

Q: Does reverse leakage specification affect substitution compatibility?

A: Reverse leakage differences (1 mA for STPS3030CG-TR versus 1.75 mA for other parts @ 30 V) represent acceptable parametric variation within the Schottky diode array category. Lower reverse leakage indicates superior performance characteristics but does not prevent substitution. Applications sensitive to leakage current may prefer STPS3030CG-TR; general applications accept all listed parts.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: REACH Affected status (32CTQ030S) indicates the part may contain substances of concern under REACH regulations but complies with applicable restrictions. REACH Unaffected status (Vishay and STMicroelectronics parts) indicates the part does not contain restricted substances. Selection depends on end-use application regulatory requirements and supply chain compliance policies.

Q: Can these parts be used in applications requiring -55°C minimum operating temperature?

A: 32CTQ030S, VS-32CTQ030S-M3, and VS-32CTQ030STRL-M3 specify operating temperature range -55°C to 150°C and are suitable for low-temperature applications. STPS3030CG-TR specifies only maximum temperature (150°C) without minimum temperature specification. For applications requiring -55°C operation, use 32CTQ030S or Vishay parts.

Q: Are all parts ROHS3 compliant?

A: All four parts—32CTQ030S, STPS3030CG-TR, VS-32CTQ030S-M3, and VS-32CTQ030STRL-M3—are ROHS3 compliant. This certification applies to all substitute options listed.
