30CPQ045 Equivalent & Substitute Parts

Part Overview

The 30CPQ045 is a Schottky diode array manufactured by SMC Diode Solutions, configured as a 1 Pair Common Cathode rectifier with a maximum reverse voltage rating of 45 V. The device is packaged in a TO-247-3 through-hole format and is designed for fast recovery applications with switching speeds of 500 ns or less at currents exceeding 200 mA. This component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate specific application requirements where alternative manufacturers or package variants may be preferred while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the 30CPQ045 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Maximum reverse voltage (Vr): 45 V
• Forward voltage (Vf) at 15 A: 540 mV
• Recovery speed: Fast Recovery ≤ 500 ns, > 200 mA
• Operating temperature range: -55°C to 150°C

Mechanical Equivalence Criteria:

• Package type: TO-247-3
• Mounting method: Through Hole
• Compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The substitute part VS-30CPQ045-N3 meets all electrical and mechanical equivalence criteria. Differences in reverse leakage current (1.75 mA versus 1 mA at 45 V) and supplier device package designation (TO-247AC versus TO-247AD) do not preclude functional substitution, as both remain within the TO-247-3 physical and electrical envelope and maintain identical primary performance characteristics.

Engineering Selection Recommendations

Primary Part Selection (30CPQ045): The 30CPQ045 from SMC Diode Solutions is the specified component and remains the first choice for new designs and production runs. This part is in active production status with full inventory availability (4,678 pcs in stock) and carries ROHS3 compliance certification. The component is REACH Affected, which may require documentation in certain regulatory jurisdictions.

Substitute Part Selection (VS-30CPQ045-N3): The VS-30CPQ045-N3 from Vishay General Semiconductor - Diodes Division is a direct electrical and mechanical equivalent suitable for substitution when supply constraints affect the primary part. This substitute maintains identical electrical performance across all critical parameters and is also ROHS3 compliant. The substitute carries REACH Unaffected status, which may provide regulatory advantages in specific applications. Current inventory availability is 1,841 pcs in stock.

Both parts are suitable for applications requiring 45 V Schottky diode arrays in TO-247-3 through-hole packages with fast recovery characteristics and common cathode configuration. Selection between the primary and substitute part should be based on supply availability, lead time requirements, and regulatory compliance documentation needs specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can VS-30CPQ045-N3 be used as a direct replacement for 30CPQ045 in existing designs?

A: Yes. The VS-30CPQ045-N3 is electrically and mechanically equivalent to the 30CPQ045. Both devices share identical diode configuration, reverse voltage rating, forward voltage characteristics, recovery speed, operating temperature range, and TO-247-3 package format. The parts are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the significance of the difference in reverse leakage current between the two parts?

A: The 30CPQ045 specifies a maximum reverse leakage of 1 mA at 45 V, while the VS-30CPQ045-N3 specifies 1.75 mA at 45 V. Both values remain within acceptable operating parameters for Schottky diode arrays in this voltage class. The difference does not affect functional compatibility or circuit performance in standard rectification applications.

Q: Are the TO-247AD and TO-247AC package designations interchangeable?

A: Yes. Both TO-247AD and TO-247AC designations refer to the same TO-247-3 physical package format with identical pin configuration, lead spacing, and mounting characteristics. The suffix letters indicate minor variations in supplier documentation or manufacturing process but do not affect mechanical or electrical compatibility.

Q: What are the key parameters that determine substitution eligibility for this diode array?

A: Substitution eligibility is determined by equivalence in the following parameters: diode configuration (1 Pair Common Cathode), technology (Schottky), maximum reverse voltage (45 V), forward voltage at rated current (540 mV @ 15 A), recovery speed (≤ 500 ns), operating temperature range (-55°C to 150°C), and physical package format (TO-247-3 through-hole). All these parameters must match or exceed the original specification.

Q: Does REACH compliance status affect the choice between these two parts?

A: REACH compliance status is a regulatory consideration specific to end-market requirements and supply chain documentation. The 30CPQ045 is REACH Affected, while the VS-30CPQ045-N3 is REACH Unaffected. Applications subject to REACH regulations may benefit from selecting the substitute part to simplify compliance documentation. Both parts are ROHS3 compliant and suitable for regulated markets.

Q: Are there any thermal or current rating differences between these parts?

A: Both parts share identical thermal operating ranges (-55°C to 150°C junction temperature) and are rated for 15 A average rectified current per diode. No thermal or current rating differences exist between the 30CPQ045 and VS-30CPQ045-N3.
