FEP30-CP Equivalent & Substitute Parts

Part Overview

The FEP30-CP is a general-purpose diode array manufactured by Vishay General Semiconductor - Diodes Division. This component features a 1 Pair Common Cathode configuration rated for 150 V DC reverse voltage and 15 A average rectified current per diode. The device is housed in a TO-247AD (TO-3P-3, SC-65-3) through-hole package and is currently in active product status with 984 pieces available in stock.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications requiring alternative electrical or compliance characteristics within the diode rectifier category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FEP30-CP is permissible with components that maintain compatibility across the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Current - Average Rectified (Io): 15 A per diode minimum
• Mounting Type: Through Hole
• Technology: Standard

Allowable Parameter Variations:

• Voltage - DC Reverse (Vr): Equal to or greater than 150 V
• Voltage - Forward (Vf): Within acceptable circuit operating margins
• Reverse Recovery Time (trr): Fast recovery classification maintained
• Operating Temperature Range: Maximum junction temperature of 150°C or higher
• Package / Case: Physically compatible through-hole packages (TO-247 variants)

The STTH3002CW from STMicroelectronics meets these substitution criteria with enhanced electrical characteristics and improved compliance status.

Parameter Comparison

Engineering Selection Recommendations

FEP30-CP (Vishay General Semiconductor):

• Primary selection for applications with established design validation and existing inventory requirements
• Suitable for designs operating within 150 V DC reverse voltage specification
• RoHS non-compliant status requires verification against end-product regulatory requirements
• Active product status ensures continued availability

STTH3002CW (STMicroelectronics):

• Recommended for new designs and applications requiring RoHS3 compliance
• Higher DC reverse voltage rating (200 V) provides additional design margin for overvoltage protection
• Faster reverse recovery time (22 ns vs. 35 ns) reduces switching losses in high-frequency applications
• Higher maximum junction temperature (175°C) extends thermal operating range
• TO-247-3 package maintains through-hole mounting compatibility with standard PCB layouts
• Higher inventory availability (4980 pieces) supports production volume requirements

Both components are active products with identical current ratings and diode configuration, ensuring functional equivalence in applications designed within the FEP30-CP electrical envelope.

Frequently Asked Questions (FAQ)

Q: Can STTH3002CW directly replace FEP30-CP in existing designs?

A: Yes, within the electrical operating envelope of the original design. The STTH3002CW maintains the same 15 A current rating and 1 Pair Common Cathode configuration. The higher 200 V reverse voltage rating is backward-compatible with 150 V applications. Both components use through-hole mounting in compatible TO-247 package variants. Verify PCB footprint compatibility with the specific package designation (TO-247-3 vs. TO-3P-3).

Q: What are the key differences between these parts?

A: The STTH3002CW provides higher reverse voltage (200 V vs. 150 V), faster reverse recovery time (22 ns vs. 35 ns), higher maximum junction temperature (175°C vs. 150°C), and RoHS3 compliance. Forward voltage is slightly higher (1.05 V vs. 950 mV at 15 A). These differences result in improved thermal performance and regulatory compliance without compromising current-handling capability.

Q: Are the packages physically interchangeable?

A: Both components use through-hole TO-247 package variants. FEP30-CP uses TO-3P-3 (SC-65-3) and STTH3002CW uses TO-247-3. These packages have identical pin configurations and mounting footprints on standard PCB layouts. Verify specific package dimensions against your PCB design documentation.

Q: Which part should be selected for new product designs?

A: STTH3002CW is recommended for new designs due to active product status, RoHS3 compliance, superior thermal characteristics, and faster switching performance. FEP30-CP remains suitable for legacy design maintenance and applications with established validation history.

Q: What is the impact of the forward voltage difference?

A: The STTH3002CW forward voltage is 100 mV higher at 15 A (1.05 V vs. 950 mV). This results in approximately 1.5 W additional power dissipation per diode in continuous operation at maximum current. Thermal design calculations should account for this difference in high-current applications.

Q: Are there compliance considerations for part selection?

A: FEP30-CP is RoHS non-compliant. STTH3002CW is ROHS3 compliant. Applications subject to RoHS directives or customer compliance requirements must use STTH3002CW. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.
