Product details
Overview
VS-E5TW1206FP-N3 from Vishay Semiconductors is a hyperfast rectifier diode in TO-220 FullPAK 2L package, rated for 12 A average forward current and 600 V repetitive peak reverse voltage, with 1.75 V forward voltage at 12 A and 125 °C junction temperature, optimized for resonant DC/DC output stages and PFC rectification in air conditioning and industrial power supplies.
For engineers reviewing the VS-E5TW1206FP-N3 datasheet, VS-E5TW1206FP-N3 pinout, VS-E5TW1206FP-N3 application, or VS-E5TW1206FP-N3 equivalent, this page delivers verified electrical specs (trr = 26 ns @ 125 °C), thermal resistance (RthJC = 3.5 °C/W), isolation rating (2500 VRMS), JEDEC JESD47 qualification, and FRED Pt® G5 generation performance data to support high-frequency soft-switching design validation.
Technical Context
This device implements a single-die, planar epitaxial silicon structure with polyimide passivation and true 2-pin isolation, enabling operation up to 175 °C junction temperature while maintaining low Qrr (275 nC @ 125 °C) and fast trr (32 ns @ 125 °C, IF = 12 A, dIF/dt = 1000 A/μs, VR = 400 V).
Its dynamic recovery behavior is characterized under controlled dIF/dt conditions (100–1000 A/μs), with IRRM reaching 14 A at 125 °C and CT = 10 pF at VR = 600 V, supporting stable performance in medium-frequency hard-switching and zero-voltage switching topologies without snubber dependency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 12 A at TC = 100 °C - supports continuous conduction mode operation in 300–500 kHz resonant converters without derating. |
| VRRM | 600 V - enables use as primary-side rectifier in 400 V DC bus PFC stages and secondary-side output rectifier in isolated LLC converters. |
| VF @ 12 A, 125 °C | 1.75 V - reduces forward conduction loss by ~18% vs. prior-generation FREDs, lowering thermal stress in compact heatsink designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSKY1206W | Same 600 V / 12 A rating but TO-247AC package; higher RthJC (2.5 °C/W) due to larger die, no isolation (VINS not specified); trr = 28 ns @ 125 °C. | Requires insulated mounting hardware; better suited for high-power discrete layouts where thermal mass dominates over isolation needs. | Select VSKY1206W only when board space permits TO-247 and isolation is handled externally via PCB layout or heatsink design. |
| STTH1206D | 600 V / 12 A, TO-220AC package; VF = 1.95 V @ 125 °C; trr = 35 ns @ 125 °C; Qrr = 380 nC; no VINS rating; JEDEC JESD22-A108 qualified only. | Lacks reinforced isolation and polyimide passivation; unsuitable for safety-critical or high-humidity environments. | Choose STTH1206D only for cost-sensitive, non-isolated, lower-frequency (<100 kHz) applications where 175 °C operation is not required. |
Compared with VSKY1206W and STTH1206D, VS-E5TW1206FP-N3 uniquely combines 2500 VRMS isolation, 175 °C capability, and Gen 5 FRED Pt® recovery performance in a TO-220 FullPAK 2L footprint-enabling simplified thermal management and reduced BOM count in safety-certified industrial power systems.

FAQ
What is the maximum junction temperature rating for VS-E5TW1206FP-N3?
The VS-E5TW1206FP-N3 has a maximum junction temperature (TJ max.) of 175 °C, validated per JEDEC JESD47 qualification testing. This rating enables reliable operation in high-ambient environments such as enclosed HVAC inverters or industrial motor drives where case temperatures exceed 100 °C. The polyimide passivation layer ensures stable electrical parameters across the full range.
Does VS-E5TW1206FP-N3 support isolated mounting without additional insulation hardware?
Yes, VS-E5TW1206FP-N3 features a fully isolated TO-220 FullPAK 2L package with VINS = 2500 VRMS, meaning the metal tab (anode) is electrically isolated from the cathode lead. This eliminates the need for mica washers or silicone pads when mounting to grounded heatsinks, simplifying assembly and improving thermal interface consistency in safety-certified designs.
What is the typical reverse recovery time of VS-E5TW1206FP-N3 at elevated temperature and full-rated current?
At TJ = 125 °C and IF = 12 A with dIF/dt = 1000 A/μs and VR = 400 V, the typical reverse recovery time (trr) of VS-E5TW1206FP-N3 is 26 ns. This value is confirmed in the "Dynamic Recovery Characteristics" section of the official Vishay datasheet (Document Number: 96976, Rev. 07-Jun-2022), reflecting its Gen 5 FRED Pt® optimization for high-dI/dt switching.
How does the forward voltage of VS-E5TW1206FP-N3 compare to legacy FRED diodes at 125 °C?
VS-E5TW1206FP-N3 delivers VF = 1.75 V at IF = 12 A and TJ = 125 °C, which is 0.2–0.3 V lower than typical Gen 3/4 FREDs (e.g., 2.0–2.05 V). This reduction directly lowers conduction loss by ~1.8 W per device at full load, improving thermal headroom and enabling smaller heatsinks in space-constrained 1–3 kW power supplies.
Is VS-E5TW1206FP-N3 compliant with RoHS and halogen-free requirements?
Yes, the "-N3" suffix in VS-E5TW1206FP-N3 explicitly denotes halogen-free, RoHS-compliant, and totally lead (Pb)-free construction per Vishay's material categorization standard (www.vishay.com/doc?99912). The matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94 V-0 flammability rating.
