Product details

Overview

FEP30-CP from Vishay General Semiconductor is a dual common-cathode ultrafast rectifier in TO-3P (TO-247AD) package, rated for 150 V repetitive peak reverse voltage, 30 A average forward current, and 35 ns reverse recovery time. It delivers low forward voltage (1.3 V at 15 A), high surge capability (300 A), and operates up to 150 °C junction temperature - optimized for high-frequency switching power supplies and DC/DC converters.

For engineers reviewing the FEP30-CP datasheet, FEP30-CP pinout, FEP30-CP application, or FEP30-CP equivalent, key selection criteria include its dual common-cathode configuration, 35 ns trr, 1.3 V VF at 15 A, thermal resistance of 1.0 °C/W per diode, and TO-247AD mechanical compatibility with standard heatsink mounting.

Technical Context

The FEP30-CP integrates two ultrafast silicon rectifier dies sharing a common cathode terminal, enabling compact dual-output or phase-leg freewheeling topologies. Its glass-passivated junction ensures stable performance under thermal cycling and high dv/dt stress.

Designed for hard-switched SMPS operating above 50 kHz, it minimizes switching losses via low trr (35 ns) and low junction capacitance (145 pF at 4 V), while maintaining low conduction loss through controlled forward voltage and low thermal resistance (1.0 °C/W per diode).

Key Specifications

V_RRM	150 V - supports 150 V DC blocking in boost PFC or secondary-side rectification without derating
I_F(AV)	30 A at T_C = 100 °C - enables high-power output in compact heatsink-mounted designs
t_rr	35 ns - reduces turn-off switching loss and EMI in >100 kHz converters
V_F @ 15 A	1.3 V - lowers conduction loss and thermal load vs. standard fast rectifiers
R_θJC	1.0 °C/W per diode - allows precise thermal design with single heatsink interface
I_FSM	300 A (8.3 ms half-sine) - withstands inrush and transient overloads in industrial PSUs
C_J	145 pF @ 4 V, 1 MHz - limits capacitive coupling and ringing in high-dv/dt gate-drive paths

Pinout & Package

Package: TO-3P (TO-247AD), isolated metal tab, matte tin-plated leads, UL 94 V-0 molding compound, 10 in-lb max mounting torque.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultrafast dual rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06TV1	600 V V_RRM, 35 ns trr, but 1.7 V V_F @ 15 A and TO-247AC package (non-isolated tab)	Higher voltage rating suits 400 V bus systems; higher VF increases conduction loss at 30 A	Select when system requires >300 V blocking; verify heatsink isolation if using metal-mount configuration
IXYS MBR30H150CT	Schottky construction, 150 V V_RRM, 0.85 V V_F @ 15 A, but limited to 125 °C T_J and higher leakage (1 mA @ 125 °C)	Better efficiency at light loads; unsuitable for high-temperature or high-reliability industrial environments	Prefer for low-VF priority in ambient <85 °C; avoid where reverse leakage or 150 °C operation is required

Compared with STTH30L06TV1 and MBR30H150CT, the FEP30-CP offers balanced trade-offs: lower VF than the STTH part, higher T_J rating than the IXYS Schottky, and isolated TO-247AD packaging ideal for grounded heatsink layouts in industrial power supplies.

FAQ

What is the maximum junction temperature rating for the FEP30-CP?

The FEP30-CP has a maximum junction temperature (T_J) of 150 °C, enabling reliable operation in high-ambient industrial environments. This rating is validated per Vishay's thermal characterization and allows full 30 A average current derating only down to 100 °C case temperature. The device maintains specified electrical parameters up to this limit, supporting designs where heatsink space is constrained.

Does the FEP30-CP have an isolated package, and why does that matter?

Yes, the FEP30-CP uses a TO-3P (TO-247AD) package with electrically isolated metal tab. This isolation eliminates the need for insulating washers or pads when mounting directly to a grounded heatsink - reducing thermal resistance and assembly complexity. It is critical in high-voltage systems where primary-to-secondary creepage/clearance must be maintained without compromising thermal performance.

What is the reverse recovery time (t_rr) of the FEP30-CP, and how is it measured?

The FEP30-CP has a typical reverse recovery time (t_rr) of 35 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss and EMI in hard-switched topologies. The 35 ns spec applies specifically to the FEP30-CP variant within the FEP30xP family.

Can the FEP30-CP replace two separate TO-247 fast rectifiers in a design?

Yes, the FEP30-CP replaces two discrete TO-247 ultrafast rectifiers in dual-anode, common-cathode configurations - such as center-tapped transformer outputs or interleaved freewheeling paths. Its pinout (Anode1–Cathode–Anode2) matches standard layout footprints, and its shared thermal path simplifies heatsinking. However, PCB layout must preserve symmetry between anode traces to avoid current imbalance.

Is the FEP30-CP RoHS-compliant and qualified for lead-free soldering?

Yes, the FEP30-CP carries the "E3" suffix, indicating RoHS compliance and qualification for lead-free soldering per J-STD-002 and JESD22-B102. It withstands solder dip at 260 °C for 40 seconds and passes JESD201 Class 1A whisker testing. Matte tin-plated leads ensure consistent wetting and long-term intermetallic stability in reflow and wave solder processes.
