Product details
Overview
FES16DT-E3/45 from Vishay General Semiconductor is an ultrafast plastic rectifier diode in TO-220AC package, rated for 200 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 forward voltage drop (VF = 1.30 V at 16 A), and high surge capability (IFSM = 250 A), designed for high-frequency switching power supplies and DC/DC converters.
For engineers reviewing the FES16DT-E3/45 datasheet, FES16DT-E3/45 pinout, FES16DT-E3/45 application, or FES16DT-E3/45 equivalent, key selection criteria include its 200 V blocking rating, 35 ns trr for minimal switching loss, TO-220AC thermal performance (RθJC = 1.2 °C/W), and RoHS-compliant commercial-grade construction with matte tin-plated leads.
Technical Context
This device operates as a single-anode, single-cathode unidirectional power rectifier with ultrafast recovery optimized for hard-switched topologies. Its 35 ns trr and 1.30 V VF at 16 A enable high efficiency in 100–500 kHz SMPS designs, while the 1.2 °C/W junction-to-case thermal resistance supports reliable conduction at TC = 100 °C.
The TO-220AC package provides direct heatsink mounting (max torque 10 in-lbs) and meets UL 94 V-0 flammability. It is not AEC-Q101 qualified - that designation applies only to HM3-suffix variants in D2PAK; FES16DT-E3/45 is commercial grade with E3 suffix (RoHS-compliant, JESD 201 Class 1A whisker test).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-repetitive reverse voltage the diode blocks without breakdown; sets upper limit for input/output voltage rails in buck, boost, or flyback stages |
| IF(AV) | 16 A at TC = 100 °C - continuous DC forward current capability under heatsink-cooled conditions; defines minimum heatsink sizing requirement |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables operation up to ~3 MHz effective switching frequency with low commutation loss |
| VF | 1.30 V at 16 A - forward voltage drop determining conduction loss (20.8 W max at full load); lower than standard FRDs for improved efficiency |
| RθJC | 1.2 °C/W - thermal resistance from junction to case; allows calculation of junction temperature rise above heatsink temperature (e.g., +19.2 °C at 16 A) |
| IFSM | 250 A - peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in industrial power supplies |
| TJ max. | 150 °C - maximum allowable junction temperature; sets safe operating area boundary with derating curves |
Pinout & Package
Package: TO-220AC - 3-lead, through-hole, isolated tab (cathode-connected tab), intended for mechanical mounting to heatsink with insulating washer if required. Lead finish: matte tin, solderable per J-STD-002/JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Input terminal for forward current flow; connects to switching node or transformer secondary in rectification path |
| Pin 2 (Cathode) | Cathode connection | Output terminal for forward current; electrically tied to metal tab; requires isolation when mounted to grounded heatsink |
| Metal Tab (K) | Cathode (common with Pin 2) | Thermally conductive interface to heatsink; electrically identical to Pin 2; must be insulated unless system ground reference permits direct connection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated pellet chip junction | Enables stable long-term reliability and moisture resistance without epoxy encapsulation vulnerability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | 200 V VRRM, 16 A IF(AV), 30 ns trr, TO-220AC, VF = 1.25 V @ 16 A | Slightly faster recovery and lower VF; same thermal resistance (1.2 °C/W) | Preferred where <5 ns trr reduction improves EMI or efficiency margin; verify layout compatibility with ST's leadform |
| IXYS MUR1620CT | 200 V VRRM, dual common-cathode configuration (2 × 8 A), TO-220AB package, VF = 1.20 V @ 8 A per die | Dual-diode topology enables interleaved or dual-output designs; not single-diode drop-in | Select when dual-channel rectification or space-constrained PCB layout favors shared cathode; requires circuit redesign |
Compared with STTH1602CW and IXYS MUR1620CT, FES16DT-E3/45 offers balanced trade-offs: identical package and thermal performance to STTH1602CW but slightly higher VF, and simpler single-diode implementation versus the dual MUR1620CT - making it optimal for cost-sensitive, single-output SMPS where proven Vishay reliability is prioritized.

FAQ
What is the maximum junction temperature rating for FES16DT-E3/45?
The FES16DT-E3/45 has a maximum junction temperature (TJ max.) of 150 °C. This rating defines the upper thermal limit for safe operation; exceeding it risks permanent degradation. Derating curves in the Vishay datasheet (Document 88599) specify allowable IF(AV) reduction as case temperature rises above 25 °C, ensuring FES16DT-E3/45 remains within safe SOA across ambient and heatsink conditions.
Is FES16DT-E3/45 AEC-Q101 qualified?
No, FES16DT-E3/45 is not AEC-Q101 qualified. The AEC-Q101 qualification applies only to HM3-suffix variants (e.g., FESB16DT-HM3/I) in D2PAK (TO-263AB) package. FES16DT-E3/45 carries the E3 suffix, indicating RoHS-compliant commercial grade with JESD 201 Class 1A whisker resistance - suitable for industrial and computing applications but not automotive under hood.
What does the "/45" suffix mean in FES16DT-E3/45?
The "/45" in FES16DT-E3/45 denotes the packaging configuration: 45 devices per tube. This is a standard Vishay ordering code convention for TO-220AC parts. The base part number FES16DT-E3 identifies the electrical and material specifications; "/45" specifies tube packaging (vs. tape-and-reel for D2PAK variants), affecting handling, automation compatibility, and minimum order quantities.
Can FES16DT-E3/45 be used as a direct replacement for FES16CT-E3/45?
Yes, FES16DT-E3/45 can replace FES16CT-E3/45 in most designs, as both share identical TO-220AC package, thermal characteristics (RθJC = 1.2 °C/W), and forward voltage (VF = 1.30 V at 16 A). The key difference is reverse voltage rating: FES16CT is rated for 150 V VRRM, while FES16DT is rated for 200 V VRRM - offering higher margin in 200 V bus applications without changing layout or thermal design.
What is the reverse recovery time (trr) test condition for FES16DT-E3/45?
The reverse recovery time (trr) of 35 ns for FES16DT-E3/45 is measured under standardized conditions: IF = 0.5 A forward current, IR = 1.0 A reverse current, and Irr = 0.25 A reverse recovery current, per JEDEC methods. This test reflects real-world switching behavior in hard-commutated circuits and is validated in Vishay Document 88599, page 2 - not extrapolated or estimated.
