Product details
Overview
VS-E5TW1506FP-N3 from Vishay Semiconductors is a hyperfast rectifier diode in TO-220 FullPAK 2L package, rated for 600 V repetitive peak reverse voltage and 15 A average forward current, with 17 ns typical reverse recovery time at 25 °C and 1.5 V forward voltage at 15 A and 125 °C - optimized for output rectification in resonant DC/DC converters and PFC stages in air conditioning and industrial power supplies.
For engineers reviewing the VS-E5TW1506FP-N3 datasheet, VS-E5TW1506FP-N3 pinout, VS-E5TW1506FP-N3 application, or VS-E5TW1506FP-N3 equivalent, key selection criteria include ultra-low trr/Qrr trade-off, 175 °C junction rating, fully isolated 2500 VRMS package, and FRED Pt® G5 generation performance in high-frequency hard-switching and soft-switched topologies.
Technical Context
This device implements a silicon planar hyperfast recovery structure with polyimide passivation, delivering tightly controlled reverse recovery characteristics (trr = 17–39 ns, Qrr = 97–435 nC) across temperature and dIF/dt conditions. Its true 2-pin configuration and low series inductance (8 nH) minimize parasitic ringing in high-dI/dt switching environments.
The TO-220 FullPAK 2L package provides full electrical isolation (VINS = 2500 VRMS), thermal resistance of 3.3 °C/W (junction-to-case), and JEDEC JESD47-qualified reliability up to 175 °C TJ - enabling robust operation in space-constrained, thermally demanding industrial and HVAC power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports primary-side PFC and secondary-side DC/DC rectification in 400 V bus systems with margin. |
| IF(AV) | 15 A at TC = 98 °C - enables compact heatsink design in medium-power (≈300–500 W) resonant converters. |
| VF @ 15 A, 125 °C | 1.5 V - reduces conduction loss by ≈15 % vs. prior-generation FREDs, improving efficiency at elevated temperatures. |
| trr (typ.) | 17 ns at TJ = 25 °C, IF = 1.0 A, dIF/dt = 100 A/μs - ensures minimal switching loss and EMI in >100 kHz topologies. |
| Qrr (typ.) | 97 nC at TJ = 25 °C - lowers tail-current energy dissipation during turn-off, critical for ZVS/ZCS circuit stability. |
| TJ max. | 175 °C - allows sustained operation under transient overloads without derating in sealed enclosures. |
| RthJC | 3.3 °C/W - supports direct mounting to heatsinks with predictable thermal path for thermal management. |
Pinout & Package
TO-220 FullPAK 2L package with fully isolated construction (2500 VRMS), matte tin-plated leads, UL 94 V-0 molding compound, and exposed copper thermal pad on underside for enhanced heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Value: 8 nH series inductance and low CT (19 pF @ 600 V) suppress voltage spikes >10 % lower than legacy TO-220 diodes. | Use Scenario: Bidirectional energy transfer path in online UPS inverters where reverse recovery behavior affects THD and transformer saturation. IC Role / Device Role / Timing Role: Clamping and commutation diode in IGBT-based H-bridge - controls reverse recovery charge injection into DC link capacitors. Use Value: Tight Qrr distribution (±15 % typ.) ensures consistent current tail duration across units, minimizing output current imbalance in parallel modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hyperfast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-E5PX1506L-N3 | Same FRED Pt® G5 die, but TO-247AC package - higher RthJC (2.5 °C/W), larger footprint, no integrated isolation barrier. | Preferred where thermal budget allows larger heatsink and PCB real estate; not suitable for isolated mounting constraints. | Select VS-E5PX1506L-N3 only when junction-to-ambient thermal path requires lower RthJA and board-level isolation is handled externally. |
| ON Semiconductor MUR1560CT | Legacy ultrafast rectifier (not FRED Pt®); trr = 50 ns (typ.), VF = 1.85 V @ 15 A/125 °C, no polyimide passivation or JEDEC JESD47 qualification. | Suitable for cost-sensitive, non-critical 60–100 kHz applications where efficiency and reliability margins are relaxed. | Choose MUR1560CT only for legacy redesigns with fixed layout and no thermal or EMI constraints - not recommended for new 200+ kHz designs. |
Compared with VS-E5PX1506L-N3 and MUR1560CT, the VS-E5TW1506FP-N3 uniquely combines TO-220 footprint, full 2500 VRMS isolation, 17 ns trr, and 175 °C rating - making it the only option for space-limited, high-reliability, high-frequency industrial PFC and DC/DC outputs requiring no external isolation.

FAQ
What is the maximum allowable case temperature for VS-E5TW1506FP-N3 during continuous operation?
The VS-E5TW1506FP-N3 has a maximum junction temperature of 175 °C and a thermal resistance of 3.3 °C/W (junction-to-case). At 15 A average forward current and 1.5 V forward drop, power dissipation is ≈22.5 W; thus, maximum case temperature is limited to ≈100 °C to maintain safe junction margin. Derating curves in Figure 4 confirm 15 A is sustainable at TC ≤ 98 °C.
Does VS-E5TW1506FP-N3 support isolated mounting without additional insulation?
Yes, the VS-E5TW1506FP-N3 features full electrical isolation with VINS = 2500 VRMS between terminals and case, enabled by its TO-220 FullPAK 2L construction. No external insulating washer or pad is required when mounting the tab (anode) to a grounded heatsink - the polyimide passivation and molded isolation barrier meet reinforced insulation requirements per IEC 60950-1.
How does the reverse recovery charge (Qrr) of VS-E5TW1506FP-N3 vary with temperature and dIF/dt?
Per datasheet Figures 8 and 11, Qrr for VS-E5TW1506FP-N3 increases from 97 nC (25 °C) to 435 nC (125 °C) at IF = 15 A and VR = 400 V. It also rises with dIF/dt - from ≈100 nC at 100 A/μs to ≈250 nC at 1000 A/μs (125 °C). This predictable, monotonic behavior simplifies snubber design in variable-frequency resonant converters.
Is VS-E5TW1506FP-N3 compatible with lead-free reflow soldering processes?
Yes, VS-E5TW1506FP-N3 uses matte tin-plated leads qualified per J-STD-002 and supports standard lead-free reflow profiles (peak temperature ≤ 260 °C, 60 s max above 217 °C). The TO-220 FullPAK 2L package's UL 94 V-0 molding compound and polyimide passivation ensure integrity through multiple thermal cycles without delamination or parameter shift.
What is the significance of the "N3" suffix in VS-E5TW1506FP-N3?
The "N3" suffix in VS-E5TW1506FP-N3 denotes halogen-free, RoHS-compliant, and totally lead (Pb)-free construction per Vishay's environmental specification. It confirms compliance with JEDEC JS709B and IPC-1752A, with all materials verified to contain <900 ppm bromine and <900 ppm chlorine, and zero lead content across die, leadframe, mold compound, and plating.
