Equivalent & Substitute Parts for 30EPF10

Part Overview

The Vishay 30EPF10 is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 30 A average rectified current in a TO-247AC Modified through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design and procurement requirements. The 30EPF10 operates across a junction temperature range of -40°C to 150°C and exhibits fast recovery characteristics with a reverse recovery time of 450 ns. Due to its obsolete status and non-compliance with RoHS3 standards, alternative components with active product status and current regulatory compliance are required for new designs and production continuity.

Substitute Part Grouping Explanation

Substitution of the 30EPF10 is determined by strict equivalence across the following critical parameters: voltage rating (1000 V DC reverse), current rating (30 A average rectified), fast recovery speed classification (≤ 500 ns), through-hole mounting type, and compatible package form factors. Substitute parts are grouped into two categories based on these criteria:

Category 1: Direct Parametric Equivalents Parts that maintain identical voltage, current, and speed specifications with active product status and RoHS3 compliance. These parts are pin-compatible or mechanically compatible within the same package family.

Category 2: Functional Equivalents with Parameter Variations Parts that meet the 1000 V and 30 A requirements but may exhibit different forward voltage characteristics, reverse recovery times, or reverse leakage currents. These parts are suitable for applications where the primary electrical specifications (voltage and current) are the controlling factors.

Engineering Selection Recommendations

Primary Recommendation: VS-30EPF10-M3 The VS-30EPF10-M3 from Vishay General Semiconductor - Diodes Division is the direct equivalent replacement for the obsolete 30EPF10. This part maintains identical electrical specifications (1000 V, 30 A, 1.41 V forward voltage, 450 ns recovery time) and is packaged in the same TO-247-2 form factor. The part is active with ROHS3 compliance and represents the lowest-risk substitution path for existing designs.

Secondary Recommendation: VS-30APF10-M3 The VS-30APF10-M3 provides equivalent electrical performance with identical voltage, current, and recovery characteristics. The primary difference is the TO-247-3 package variant, which may require PCB layout verification for mechanical compatibility. This part is active and ROHS3 compliant.

Functional Equivalents for Current-Rated Applications: STTH3010W The STMicroelectronics STTH3010W meets the 1000 V and 30 A specifications with improved reverse recovery time (100 ns versus 450 ns) and significantly lower reverse leakage current (15 µA versus 100 µA). The DO-247-2 package is mechanically compatible with TO-247-2 applications. This part is active and ROHS3 compliant.

Higher Current Capability: STTH6010WY The STMicroelectronics STTH6010WY provides 60 A current rating with 1000 V voltage rating, suitable for applications requiring current margin above the 30 A specification. Forward voltage is 2 V at 60 A with 115 ns recovery time. The DO-247-2 package is mechanically compatible. This part is active, ROHS3 compliant, and carries automotive grade qualification.

Current-Limited Alternatives: APT15D100BG and APT15DQ100BG The Microchip Technology APT15D100BG and APT15DQ100BG are rated for 15 A average rectified current at 1000 V. These parts are suitable only for applications where the load current does not exceed 15 A. Both parts are active and ROHS3 compliant. The APT15D100BG exhibits 260 ns recovery time, while the APT15DQ100BG exhibits 235 ns recovery time.

IXYS Alternatives: DSEI30-10A and DSEI30-10AR The IXYS DSEI30-10A and DSEI30-10AR both provide 1000 V and 30 A specifications with superior reverse recovery time (50 ns). The DSEI30-10A is packaged in TO-247-2, while the DSEI30-10AR uses the ISOPLUS247™ package. Both parts are active and ROHS3 compliant. Higher reverse leakage current (750 µA) must be evaluated for thermal management in the specific application.

Frequently Asked Questions (FAQ)

Q: Can VS-30EPF10-M3 be used as a direct replacement for 30EPF10 without PCB modifications? A: Yes. The VS-30EPF10-M3 maintains identical electrical specifications and is packaged in the same TO-247-2 form factor as the 30EPF10. No circuit modifications are required.

Q: What is the difference between VS-30EPF10-M3 and VS-30APF10-M3? A: Both parts have identical electrical specifications (1000 V, 30 A, 1.41 V forward voltage, 450 ns recovery time). The difference is the package variant: VS-30EPF10-M3 uses TO-247-2, while VS-30APF10-M3 uses TO-247-3. PCB layout compatibility must be verified for the TO-247-3 variant.

Q: Can STTH3010W replace 30EPF10 in all applications? A: STTH3010W meets the voltage and current requirements with improved performance characteristics (lower recovery time and leakage current). The DO-247-2 package is mechanically compatible with TO-247-2 footprints. Thermal design should account for the lower leakage current, which reduces junction heating.

Q: Why do some substitute parts have higher reverse leakage current? A: Reverse leakage current varies by manufacturer process technology and device design. Higher leakage (such as 750 µA in DSEI30-10A) increases junction heating at rated voltage. Thermal analysis must confirm acceptable junction temperature rise in the specific application.

Q: Are APT15D100BG and APT15DQ100BG suitable for 30 A applications? A: No. These parts are rated for 15 A average rectified current. They are suitable only for applications where the load current does not exceed 15 A. Using these parts in 30 A applications will result in device failure.

Q: What is the advantage of STTH6010WY over STTH3010W? A: STTH6010WY provides 60 A current rating compared to 30 A for STTH3010W. This provides current margin for applications with transient or peak current requirements above 30 A. Both parts maintain 1000 V voltage rating and fast recovery characteristics.

Q: Is the DSEI30-10AR ISOPLUS247™ package compatible with TO-247-2 PCB layouts? A: ISOPLUS247™ is a different package form factor than TO-247-2. PCB layout and mechanical compatibility must be verified before substitution. The electrical specifications are equivalent to DSEI30-10A (TO-247-2 variant).

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All active substitute parts listed are ROHS3 compliant. The original 30EPF10 is RoHS non-compliant, making substitution necessary for applications requiring regulatory compliance.

Q: What is the operating temperature range difference between 30EPF10 and substitute parts? A: The 30EPF10 operates from -40°C to 150°C junction temperature. Most substitute parts extend to 175°C maximum junction temperature, providing additional thermal margin. APT15D100BG and APT15DQ100BG extend to -55°C minimum, providing wider temperature range.
