STPS6045CP Equivalent & Substitute Parts

Part Overview

The STPS6045CP is a Schottky diode array manufactured by STMicroelectronics, configured as 1 pair common cathode with 45 V reverse voltage rating and 30 A average rectified current per diode. The device is packaged in TO-218-3 (SOT-93) through-hole configuration and is classified as obsolete. Due to its obsolete status, equivalent substitute parts with identical or superior electrical characteristics are necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS6045CP is determined by the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Diode configuration: 1 pair common cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 45 V minimum
• Current - Average Rectified (Io) (per Diode): 30 A minimum
• Voltage - Forward (Vf) (Max) @ If: 630 mV @ 30 A or lower
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Compliance: ROHS3 Compliant, REACH Unaffected

Substitute parts must maintain all electrical parameters at or above the specified values and comply with the same regulatory standards. Package variations (TO-218-3, TO-247-3, TO-220-3) are acceptable provided pin configuration and mounting type remain through-hole.

Engineering Selection Recommendations

STPS6045CW (STMicroelectronics)

The STPS6045CW is the primary substitute for the obsolete STPS6045CP. Both devices are manufactured by STMicroelectronics and share identical electrical specifications including 45 V reverse voltage, 30 A average rectified current, 630 mV forward voltage at 30 A, and 500 µA reverse leakage current. The STPS6045CW maintains active product status and full ROHS3 compliance. The primary difference is the package format: TO-247-3 versus TO-218-3. This substitution is suitable for applications where PCB layout can accommodate the TO-247-3 footprint.

DSB60C45PB (IXYS)

The DSB60C45PB is an alternative substitute manufactured by IXYS with identical electrical ratings for reverse voltage, average rectified current, and forward voltage. The device maintains ROHS3 compliance and through-hole mounting. The DSB60C45PB is packaged in TO-220-3 format and exhibits higher reverse leakage current (10 mA @ 45 V compared to 500 µA @ 45 V) and a reduced maximum junction temperature range (-55°C ~ 150°C versus 175°C maximum). This substitution is suitable for applications where the TO-220-3 package is preferred and the higher reverse leakage and lower maximum junction temperature are acceptable.

Both substitute parts maintain active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can STPS6045CW be used as a direct replacement for STPS6045CP?

A: The STPS6045CW is electrically equivalent to the STPS6045CP with identical voltage, current, and thermal specifications. The primary difference is the package format: TO-247-3 versus TO-218-3. Direct PCB substitution requires layout modification to accommodate the different footprint. Pin configuration and electrical function remain compatible.

Q: What is the difference between STPS6045CW and DSB60C45PB?

A: Both devices meet the core electrical requirements of 45 V reverse voltage and 30 A average rectified current. The STPS6045CW (TO-247-3) and DSB60C45PB (TO-220-3) differ in package format. The DSB60C45PB exhibits higher reverse leakage current (10 mA versus 500 µA at 45 V) and a lower maximum junction temperature (150°C versus 175°C). Package selection depends on PCB layout constraints and thermal management requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The STPS6045CP, STPS6045CW, and DSB60C45PB are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does package format affect electrical performance?

A: Package format does not alter the electrical specifications of the diode array itself. However, different packages (TO-218-3, TO-247-3, TO-220-3) have different thermal and mechanical characteristics. Package selection should be based on PCB layout, thermal dissipation requirements, and mounting constraints.

Q: Why is the STPS6045CP classified as obsolete?

A: The STPS6045CP is obsolete due to manufacturer discontinuation. Active substitute parts (STPS6045CW and DSB60C45PB) provide equivalent or superior electrical performance and ensure continued design support and procurement availability.

Q: Can DSB60C45PB be used in high-temperature applications?

A: The DSB60C45PB has a maximum junction temperature of 150°C, compared to 175°C for the STPS6045CP and STPS6045CW. Applications requiring operation above 150°C junction temperature should use STPS6045CW or the original STPS6045CP if available.
