Product details
Overview
FEP16FT-E3/45 from Vishay General Semiconductor is a dual common-cathode ultrafast plastic rectifier in TO-220AB package, rated for 400 V repetitive peak reverse voltage (VRRM), 16 A average forward current (IF(AV)), and 35 ns reverse recovery time (trr). It delivers low forward voltage drop (0.95 V at 8.0 A) and high surge capability (200 A IFSM), targeting high-frequency rectification in switching-mode power supplies.
For engineers reviewing the FEP16FT-E3/45 datasheet, FEP16FT-E3/45 pinout, FEP16FT-E3/45 application, or FEP16FT-E3/45 equivalent, key selection criteria include VRRM = 400 V, trr = 35 ns, dual common-cathode configuration, TO-220AB thermal resistance (RθJC = 2.2 °C/W per diode), and RoHS-compliant commercial-grade construction.
Technical Context
This device integrates two independent ultrafast silicon junction diodes sharing a common cathode terminal, enabling compact dual-output or interleaved rectifier topologies. Its glass-passivated chip junction ensures stable performance under thermal cycling and high dv/dt stress.
The 35 ns reverse recovery time and low 0.95 V forward voltage at 8.0 A support high-efficiency operation in 100–500 kHz SMPS designs. Thermal resistance of 2.2 °C/W per diode (junction-to-case) allows direct heatsink mounting without thermal interface material in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports DC bus rectification up to 280 V RMS input in offline SMPS |
| IF(AV) | 16 A - total average current across both diodes at TC = 100 °C |
| trr | 35 ns - enables efficient operation above 200 kHz with minimal switching loss |
| VF | 0.95 V @ 8.0 A - reduces conduction loss in high-current output stages |
| IFSM | 200 A - withstands inrush and transient surges in industrial power converters |
| RθJC | 2.2 °C/W per diode - permits direct heatsink mounting with predictable thermal rise |
| TJ max. | 150 °C - supports operation in enclosed, high-ambient environments |
Pinout & Package
Package: TO-220AB - insulated case, single-row 3-pin through-hole package with metal tab (pin 2) serving as common cathode and thermal path. Mounting torque ≤ 10 in-lbs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first diode; electrically isolated from case |
| Pin 2 | Common Cathode | Shared cathode node and thermally conductive metal tab; must be electrically connected to system ground or return plane |
| Pin 3 | Anode 2 | Input terminal for second diode; electrically isolated from case and Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability under humidity and thermal stress; eliminates need for conformal coating in industrial environments |
| Ultrafast recovery (35 ns) | Reduces reverse recovery charge (Qrr) and associated EMI in high-frequency converters |

Applications
| AC-DC Front-End Rectification | DC-DC Synchronous Rectifier Auxiliary |
|---|---|
Use Scenario: Input-stage full-wave rectification in 300–500 W offline SMPS with universal AC input (85–265 VAC). IC Role / Device Role / Timing Role: Dual common-cathode rectifier providing two independent anode inputs feeding parallel or interleaved output paths. Use Value: 400 V VRRM and 200 A IFSM ensure robustness against line surges; 35 ns trr minimizes switching loss at 250 kHz operation. | Use Scenario: Secondary-side freewheeling path in non-isolated buck converters for telecom POL modules. IC Role / Device Role / Timing Role: Dual-anode, common-cathode configuration allows shared cathode return to output capacitor bank while supporting dual-phase or redundant paths. Use Value: 0.95 V VF at 8 A reduces conduction loss by ~15% vs. standard fast recovery diodes; TO-220AB facilitates mechanical stability on high-vibration boards. |
| Inverter Freewheeling Diode | Industrial Motor Drive Snubber Path |
Use Scenario: Bidirectional freewheeling path in 3-phase IGBT inverters driving PMSM motors (1–5 kW range). IC Role / Device Role / Timing Role: Provides low-loss reverse-current path during IGBT turn-off; dual configuration supports split DC-link or phase-leg redundancy. Use Value: 150 °C TJ max. and 2.2 °C/W RθJC enable sustained operation at 100 °C ambient without derating; 35 ns trr suppresses voltage overshoot during rapid current reversal. | Use Scenario: Clamp/snubber diode network in high-dv/dt gate-drive circuits for SiC MOSFET half-bridges. IC Role / Device Role / Timing Role: Absorbs inductive energy spikes during switching transitions; common-cathode layout simplifies PCB routing to shared snubber capacitor. Use Value: Glass-passivated junction withstands >1000 V/μs dv/dt without leakage degradation; 35 ns trr ensures clean clamping without tail current oscillation. |
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 |
|---|---|---|---|
| STTH1604D | VRRM = 400 V, trr = 35 ns, but TO-220AC package (non-insulated case); RθJC = 2.5 °C/W | Requires insulating washer when mounted to grounded heatsink; slightly higher thermal resistance limits power density | Select if cost-sensitive and isolation hardware is already in BOM; verify creepage/clearance compliance for safety-critical designs |
| IXYS MUR1640CT | VRRM = 400 V, trr = 35 ns, TO-220AB package, but VF = 1.30 V @ 8 A (higher conduction loss) | Higher forward drop increases thermal load in high-duty-cycle applications; same pinout and mounting | Select only where lower cost outweighs 0.35 V VF penalty; confirm thermal margin with RθJC = 2.3 °C/W |
Compared with STTH1604D and IXYS MUR1640CT, FEP16FT-E3/45 offers insulated TO-220AB packaging for simplified heatsink integration and the lowest forward voltage (0.95 V) among 400 V dual ultrafast rectifiers-directly reducing conduction loss and thermal management complexity in space-constrained power stages.

FAQ
What is the maximum junction temperature rating for FEP16FT-E3/45?
The FEP16FT-E3/45 has a maximum junction temperature (TJ) rating of 150 °C, verified per Vishay's thermal characterization data. This allows reliable operation in enclosed enclosures or high-ambient industrial environments when mounted to an adequately sized heatsink. The device's RθJC of 2.2 °C/W per diode enables accurate thermal modeling for board-level design validation of FEP16FT-E3/45.
Is FEP16FT-E3/45 pin-compatible with other TO-220AB dual rectifiers?
Yes, FEP16FT-E3/45 uses the standard TO-220AB outline with pin 1 (anode 1), pin 2 (common cathode/tab), and pin 3 (anode 2). It matches mechanical and electrical pinout of industry-standard dual common-cathode rectifiers like MUR1640CT and STTH1604D. However, note that STTH1604D uses TO-220AC (non-insulated case), so mechanical fit does not guarantee electrical compatibility without isolation hardware for FEP16FT-E3/45.
What does the "E3/45" suffix indicate in FEP16FT-E3/45?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/45" indicates packaging in tubes of 45 units-standard for TO-220AB devices at Vishay. This distinguishes FEP16FT-E3/45 from tape-and-reel variants (e.g., FEPB16FT-M3/I) and AEC-Q101 qualified versions (HM3 suffix).
Does FEP16FT-E3/45 meet automotive qualification standards?
No, FEP16FT-E3/45 is a commercial-grade part (E3 suffix) and is not AEC-Q101 qualified. For automotive applications, Vishay offers the FEP16FTHM3 variant (HM3 suffix), which carries AEC-Q101 qualification, halogen-free construction, and JESD 201 Class 2 whisker resistance. FEP16FT-E3/45 is intended for industrial, computing, and telecom power systems where automotive-grade reliability is not mandated.
What is the typical junction capacitance of FEP16FT-E3/45?
The typical junction capacitance (CJ) of FEP16FT-E3/45 is 85 pF per diode at 4.0 V and 1 MHz, as specified in Vishay's Electrical Characteristics table. This value impacts high-frequency switching behavior and EMI filter design-particularly in snubber networks and resonant converter topologies where diode capacitance interacts with circuit inductance.
