Product details
Overview
FEP30FP-E3 from Vishay General Semiconductor is a dual common-cathode ultrafast rectifier in TO-3P (TO-247AD) package, rated for 300 V repetitive peak reverse voltage, 30 A average forward current, and 35 ns reverse recovery time. It delivers low forward voltage (0.95 V at 15 A), high surge capability (300 A), and operates up to 150 °C junction temperature - ideal for high-frequency switching power supplies and DC/DC converters.
For engineers reviewing the FEP30FP-E3 datasheet, FEP30FP-E3 pinout, FEP30FP-E3 application, or FEP30FP-E3 equivalent, key selection criteria include its dual common-cathode configuration, 35 ns trr, 0.95 V VF at 15 A, TO-247AD thermal performance (1.0 °C/W RθJC), and RoHS-compliant matte tin-plated leads.
Technical Context
The FEP30FP-E3 integrates two ultrafast silicon diodes sharing a common cathode terminal in a single TO-3P package, enabling compact dual-output or synchronous rectification topologies. Its glass-passivated junction ensures stable operation under thermal cycling and high dv/dt conditions typical in SMPS and inverters.
Designed for high-efficiency power conversion, it achieves low switching losses via fast 35 ns recovery and low 175 pF junction capacitance at 4.0 V, while maintaining robustness with 300 A IFSM and 1.0 °C/W thermal resistance per diode when mounted on a heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - supports input rectification in 240 VAC-derived DC bus systems with margin |
| IF(AV) | 30 A at TC = 100 °C - enables high-power output stages without parallel devices |
| trr | 35 ns - minimizes switching loss and EMI in 100–500 kHz SMPS designs |
| VF @ 15 A | 0.95 V - reduces conduction loss and improves system efficiency vs. standard FRDs |
| RθJC | 1.0 °C/W per diode - allows direct heatsink mounting for thermal management in space-constrained layouts |
| CJ @ 4 V | 175 pF - limits capacitive turn-on current and aids snubberless design in flyback converters |
| IFSM | 300 A (8.3 ms half-sine) - withstands inrush and transient surges in industrial power supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay FEP30GP-E3 | Higher VRRM (400 V); VF = 1.3 V at 15 A; trr = 50 ns | Better suited for 380 VAC input systems; slightly higher conduction loss | Select when higher reverse voltage margin is required and 50 ns trr is acceptable |
| ON Semiconductor MUR3060CTG | 600 V VRRM; VF = 1.7 V at 15 A; trr = 60 ns; same TO-247 package | Wider voltage range but slower recovery and higher VF increase losses in high-frequency designs | Choose only if 600 V blocking is mandatory and efficiency is secondary to voltage headroom |
Compared with FEP30GP-E3 and MUR3060CTG, the FEP30FP-E3 offers optimal balance of speed (35 ns), low VF (0.95 V), and 300 V rating for cost-sensitive, high-efficiency 240 VAC-derived power supplies - delivering lower total loss in 100–300 kHz operation without over-specifying voltage.

FAQ
What is the maximum junction temperature rating for the FEP30FP-E3?
The FEP30FP-E3 has a maximum junction temperature (TJ max.) of 150 °C, verified per Vishay's datasheet Document Number 88597. This rating allows reliable operation in high-temperature environments such as enclosed server PSUs or industrial enclosures without derating below 30 A average current when properly heatsinked. Thermal design must respect the 1.0 °C/W RθJC per diode to maintain safe TJ margins.
Does the FEP30FP-E3 have a common cathode or common anode configuration?
The FEP30FP-E3 uses a dual common-cathode configuration: Pins 1 and 3 are independent anodes, and Pin 2 is the shared cathode terminal. This layout supports dual-output rectification, interleaved designs, or freewheeling paths with unified return - confirmed in the "Circuit configuration" section and pin diagram of the official datasheet.
What is the reverse recovery time (trr) specification for the FEP30FP-E3?
The FEP30FP-E3 has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Characteristics table in Vishay's Document Number 88597. This value is specific to the FEP30FP-E3 variant and distinguishes it from higher-voltage variants like FEP30GP-E3 (50 ns) and FEP30JP-E3 (50 ns).
Is the FEP30FP-E3 RoHS-compliant and lead-free?
Yes, the FEP30FP-E3 is RoHS-compliant and lead-free, indicated by the "E3" suffix per Vishay's ordering nomenclature. It meets JESD201 Class 1A whisker test requirements and uses matte tin-plated leads solderable per J-STD-002 and JESD22-B102 - confirmed in the Mechanical Data section of the datasheet.
What package type does the FEP30FP-E3 use, and what are its key mechanical features?
The FEP30FP-E3 uses the TO-3P (TO-247AD) package: a 3-pin, isolated metal-tab power package with UL 94 V-0 flammability rating. Key features include 10 in-lbs max mounting torque, glass-passivated die, and dimensions matching industry-standard TO-247 footprints - detailed in the Package Outline Dimensions drawing on page 4 of Document Number 88597.
