Equivalent & Substitute Parts for 30CPU04

Part Overview

The 30CPU04 is a general-purpose diode array manufactured by Vishay General Semiconductor - Diodes Division, configured as a 1 Pair Common Cathode rectifier with 400V reverse voltage rating and 15A average rectified current per diode. This component is packaged in TO-247-3 through-hole configuration and belongs to the FRED Pt® series.

The 30CPU04 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this diode array configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 30CPU04 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Mounting Type: Through Hole
• Package / Case: TO-247-3

Allowable Parameter Variations: Substitute parts may exhibit differences in forward voltage (Vf), reverse recovery time (trr), reverse leakage current, and operating temperature range, provided the substitute meets or exceeds the performance envelope of the original part in the application context.

The APT15D40BCTG from Microchip Technology satisfies all mandatory matching parameters and is classified as an active product with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 30CPU04 is classified as obsolete, whereas the APT15D40BCTG is an active product with current manufacturing support. Selection of the APT15D40BCTG ensures ongoing availability and supply chain continuity.

Compliance and Certification: The APT15D40BCTG carries ROHS3 compliance certification, whereas the 30CPU04 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must transition to the APT15D40BCTG.

Electrical Performance: Both parts meet the mandatory electrical specifications for 400V reverse voltage and 15A average rectified current. The APT15D40BCTG exhibits a faster reverse recovery time (35 ns versus 60 ns), which may provide improved switching performance in high-frequency applications. The APT15D40BCTG has higher reverse leakage current (150 µA versus 10 µA at 400V), which should be evaluated in low-leakage or high-impedance circuit applications.

Temperature Range: The 30CPU04 supports a lower minimum junction temperature (-65°C versus -55°C). Applications requiring operation below -55°C require retention of the original 30CPU04 or identification of alternative substitutes with extended low-temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can the APT15D40BCTG directly replace the 30CPU04 in existing designs?

A: The APT15D40BCTG is electrically and mechanically compatible with the 30CPU04 for applications operating within the APT15D40BCTG temperature range (-55°C to 175°C) and where the higher reverse leakage current (150 µA) is acceptable. Both parts share identical diode configuration, voltage rating, current rating, and TO-247-3 package.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product status—30CPU04 is obsolete; APT15D40BCTG is active; (2) RoHS compliance—30CPU04 is non-compliant; APT15D40BCTG is ROHS3 compliant; (3) Reverse recovery time—30CPU04 is 60 ns; APT15D40BCTG is 35 ns; (4) Reverse leakage current—30CPU04 is 10 µA; APT15D40BCTG is 150 µA; (5) Minimum operating temperature—30CPU04 is -65°C; APT15D40BCTG is -55°C.

Q: Are there any package compatibility concerns?

A: Both parts use the TO-247-3 through-hole package. Pin configuration and mechanical dimensions are identical, allowing direct board-level substitution without layout modifications.

Q: Which part should be selected for new designs?

A: The APT15D40BCTG should be selected for new designs due to active product status, current manufacturing availability, and ROHS3 compliance certification.

Q: What applications require retention of the 30CPU04?

A: Applications requiring operation at junction temperatures below -55°C or with reverse leakage current specifications below 150 µA require evaluation of alternative parts, as the 30CPU04 may be the only available option meeting these constraints.
