Product details
Overview
FES16BT-E3/45 from Vishay General Semiconductor is an ultrafast plastic rectifier diode in TO-220AC package, rated for 100 V repetitive peak reverse voltage (VRRM), 16 A average forward current (IF(AV)), and 35 ns reverse recovery time (trr). It features glass passivated pellet chip junction, low switching losses, and high forward surge capability (IFSM = 250 A), making it suitable for high-frequency rectification in switching mode power supplies.
For engineers reviewing the FES16BT-E3/45 datasheet, FES16BT-E3/45 pinout, FES16BT-E3/45 application, or FES16BT-E3/45 equivalent, key selection criteria include its 100 V VRRM rating, 35 ns trr, 0.975 V forward voltage at 16 A, TO-220AC thermal resistance (RθJC = 1.2 °C/W), and RoHS-compliant commercial-grade construction with matte tin-plated leads.
Technical Context
The FES16BT-E3/45 is a single-die, single-anode/cathode ultrafast recovery rectifier optimized for high-efficiency power conversion. Its 35 ns trr and low VF (0.975 V @ 16 A) minimize conduction and switching losses in DC/DC converters and freewheeling paths.
Designed for operation up to TJ = 150 °C with MSL Level 1 moisture sensitivity and solder dip tolerance up to 275 °C for 10 s, it supports robust industrial reflow and through-hole assembly while maintaining stable reverse leakage (IR ≤ 10 μA @ 25 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback or boost converter output stages |
| IF(AV) | 16 A @ TC = 100 °C - continuous forward current handling under heatsink-cooled conditions |
| trr | 35 ns - ultrafast recovery enables >100 kHz switching without excessive switching loss or EMI |
| VF | 0.975 V @ 16 A - low forward drop reduces conduction loss and thermal load in high-current paths |
| IFSM | 250 A @ 8.3 ms - withstands inrush and transient surges common in SMPS startup and fault conditions |
| RθJC | 1.2 °C/W - enables efficient heat transfer to heatsink; supports compact thermal design with <20 W dissipation |
| IR | 10 μA @ 25 °C - low leakage preserves efficiency in standby and light-load operation |
Pinout & Package
Package: TO-220AC - insulated case, single-ended mounting, 3-pin outline (2 active terminals + heatsink tab), UL 94 V-0 compliant molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; electrically isolated from heatsink tab; connects to input/high-side node |
| Pin 2 | Cathode | Main current exit point; connected internally to metal tab; requires electrical isolation if mounted to heatsink |
| Metal Tab | Cathode (internally tied) | Primary thermal path to heatsink; must be electrically isolated unless circuit ground reference permits direct connection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated pellet chip junction | Ensures long-term reliability and stable electrical performance under thermal cycling and humidity stress |
| Ultrafast recovery (35 ns) | Reduces reverse recovery charge (Qrr), lowering EMI and enabling higher-frequency operation than standard fast rectifiers |
| Low VF (0.975 V @ 16 A) | Minimizes power loss and temperature rise in high-current rectification paths, improving system efficiency |
| High IFSM (250 A) | Provides margin against line transients and inrush currents without degradation or failure |
| RoHS-compliant, matte tin-plated leads | Ensures solderability per J-STD-002 and whisker resistance per JESD 201 Class 1A for long-term interconnect integrity |
Applications
| Switch-Mode Power Supply Output Rectification | DC/DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Used in secondary-side rectification of 50–200 kHz flyback or forward converters delivering 12–48 V outputs. IC Role / Device Role / Timing Role: Ultrafast rectifier conducting during transformer reset phase; handles 16 A DC output with minimal voltage drop and recovery loss. Use Value: 35 ns trr and 0.975 V VF reduce switching loss by ~22% vs. standard fast diodes, improving full-load efficiency by 0.8–1.2%. | Use Scenario: Placed across inductive windings in buck or synchronous rectifier-assisted converters. IC Role / Device Role / Timing Role: Freewheeling path for inductor current during high-side switch off-time; clamps voltage spike and sustains current continuity. Use Value: Low Qrr and 250 A IFSM prevent voltage overshoot and ensure reliable operation during abrupt load transients. |
| Inverter DC Bus Clamping | Industrial Motor Drive Snubber Network |
Use Scenario: Connected across IGBT collector-emitter in three-phase inverters for regenerative energy clamping. IC Role / Device Role / Timing Role: Clamp diode absorbing reactive energy during motor deceleration; operates in repetitive 10–50 kHz burst mode. Use Value: 150 °C max junction temperature and 1.2 °C/W RθJC allow sustained clamping at 16 A without derating in enclosed drives. | Use Scenario: Integrated into RC snubber networks across relay contacts or solenoid drivers in PLC I/O modules. IC Role / Device Role / Timing Role: Fast turn-off suppresses arcing and contact bounce; absorbs inductive kick within sub-microsecond timescale. Use Value: 35 ns trr ensures clean voltage collapse across inductive loads, extending contact life and reducing EMI emissions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | VRRM = 200 V, trr = 35 ns, VF = 1.15 V @ 16 A, TO-220AC | Higher VRRM supports 200 V bus designs; slightly higher VF increases conduction loss | Select when 200 V blocking is required and 0.175 V higher VF is acceptable for thermal budget |
| IXYS MUR1620CT | Dual common-cathode configuration, VRRM = 200 V, trr = 35 ns, VF = 1.1 V @ 8 A per diode | Requires redesign for single-diode topology; dual output enables interleaved or dual-rail designs | Choose only if dual-diode functionality is needed; not a drop-in replacement for FES16BT-E3/45 |
Compared with STTH1602D and IXYS MUR1620CT, the FES16BT-E3/45 offers optimal balance of 100 V rating, lowest VF (0.975 V), and single-diode simplicity-ideal for cost-sensitive, thermally constrained 12–48 V SMPS where precise 100 V blocking suffices.

FAQ
What is the maximum junction temperature rating for FES16BT-E3/45?
The FES16BT-E3/45 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay's thermal characterization and qualified for continuous operation up to this limit when mounted with appropriate heatsinking and maintained within its derated current envelope. This rating allows reliable use in enclosed industrial power supplies where ambient temperatures exceed 70 °C.
Is FES16BT-E3/45 RoHS-compliant and halogen-free?
Yes, the FES16BT-E3/45 carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and halogen-free status per IEC 61249-2-21. It uses matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance requirements.
What is the reverse recovery time (trr) specification for FES16BT-E3/45?
The FES16BT-E3/45 has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This ultrafast value is confirmed in Vishay's Electrical Characteristics table and enables efficient operation in 100–500 kHz switching applications without significant recovery-related losses.
Can FES16BT-E3/45 be used in automotive applications?
The FES16BT-E3/45 is a commercial-grade part (E3 suffix) and is not AEC-Q101 qualified. For automotive use, Vishay offers the HM3-suffixed variant (e.g., FES16BTHM3) in D2PAK package. The FES16BT-E3/45 is intended for industrial, computing, and consumer power supplies-not automotive safety-critical systems.
What is the thermal resistance from junction to case (RθJC) for FES16BT-E3/45?
The FES16BT-E3/45 exhibits a typical thermal resistance of RθJC = 1.2 °C/W, measured from junction to the mounting surface of the TO-220AC case. This value is specified in the Thermal Characteristics section and supports thermal design calculations for heatsink sizing when dissipating up to ~16 W under forced-air or moderate heatsink conditions.
