Product details
Overview
VT4060C-E3 from Vishay General Semiconductor is a dual common-cathode Trench MOS Barrier Schottky (TMBS®) rectifier in TO-220AB package, rated for 60 V reverse voltage and 2 × 20 A average forward current per diode, with ultra-low 0.32 V forward voltage at 5.0 A and 125 °C - optimized for high-efficiency DC/DC converters and reverse battery protection circuits.
For engineers reviewing the VT4060C-E3 datasheet, VT4060C-E3 pinout, VT4060C-E3 application, or VT4060C-E3 equivalent, key selection criteria include its dual common-cathode configuration, 0.48 V VF at 20 A (25 °C), 240 A IFSM surge rating, thermal resistance of 1.5 °C/W per diode, and RoHS-compliant matte tin-plated leads solderable to J-STD-002.
Technical Context
This dual Schottky rectifier integrates two independent TMBS® diodes sharing a common cathode terminal, enabling synchronous OR-ing and bidirectional freewheeling paths in compact power stages. Its trench MOS architecture delivers lower forward voltage than planar Schottky devices while maintaining low leakage and high dV/dt immunity (10,000 V/μs).
The device operates across –40 °C to +150 °C junction temperature, with thermal resistance RθJC = 1.5 °C/W per diode and 0.8 °C/W per device, supporting conduction-limited designs in space-constrained industrial and automotive power supplies where thermal management is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| RθJC per diode | 1.5 °C/W - allows direct heatsink mounting for thermal dissipation up to 20 W per diode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-40CPH06-M3/4W | Same 60 V VRRM, but TO-247AC package; higher RθJC (1.7 °C/W); VF = 0.52 V @ 20 A, 25 °C | Higher thermal mass but less efficient at elevated temperature; better suited for forced-air-cooled industrial SMPS | Select when board-level airflow is available and TO-247 mechanical fit is required |
| ON Semiconductor MBR4060CT | Planar Schottky; VF = 0.72 V @ 20 A, 25 °C; TJ max = 175 °C; no trench MOS architecture | Higher conduction loss limits use in high-density, thermally constrained designs; wider temperature range | Select only when cost sensitivity outweighs efficiency targets and thermal headroom exceeds 30 °C |
Compared with VS-40CPH06-M3/4W and MBR4060CT, the VT4060C-E3 delivers superior thermal performance (1.5 °C/W) and lowest VF at high temperature - making it optimal for compact, unventilated 48 V input power modules where junction temperature routinely exceeds 100 °C.

FAQ
What is the maximum junction temperature rating for VT4060C-E3?
The VT4060C-E3 has a maximum junction temperature (TJ max) of +150 °C, verified per JEDEC standards and confirmed in the Vishay datasheet Document Number 89381. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in Figure 1 show usable current down to ambient temperatures of –40 °C. The VT4060C-E3 must be mounted with ≤10 in-lb torque to maintain thermal interface integrity.
Is VT4060C-E3 pin-compatible with VIT4060C-E3?
No, VT4060C-E3 and VIT4060C-E3 are not pin-compatible. VT4060C-E3 uses TO-220AB packaging with leads spaced for through-hole mounting and a metal tab connected to the common cathode. VIT4060C-E3 uses TO-262AA (surface-mount variant) with gull-wing leads and no isolated tab. Their pinouts differ: TO-220AB pins are Anode1–Cathode–Anode2; TO-262AA assigns Pin 1 and Pin 2 to anodes and Pin 3 to case-connected cathode. The VT4060C-E3 requires different PCB layout and thermal design.
What is the typical forward voltage of VT4060C-E3 at 20 A and 125 °C?
The typical forward voltage of VT4060C-E3 at 20 A and 125 °C is 0.48 V, as specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet (Document Number 89381, page 2). This value is measured per diode under pulsed conditions (≤40 ms) and reflects real-world performance in thermally stressed DC/DC converter outputs. At 25 °C, VF is 0.53 V (typical) and 0.62 V (max), confirming strong temperature coefficient advantage.
Does VT4060C-E3 meet RoHS and lead-free requirements?
Yes, VT4060C-E3 is RoHS-compliant and lead-free, as indicated by the "-E3" suffix per Vishay's ordering nomenclature. It meets JESD 201 Class 1A whisker test requirements and features matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. The molding compound complies with UL 94 V-0 flammability rating. Full compliance documentation is available in Vishay's material declaration portal referenced in datasheet note.
Can VT4060C-E3 be used in reverse battery protection with 24 V systems?
Yes, VT4060C-E3 is explicitly recommended for reverse battery protection in 24 V systems, as stated in the "TYPICAL APPLICATIONS" section of the Vishay datasheet. Its 60 V VRRM provides 150 % margin over 24 V nominal, and its 240 A IFSM handles jump-start surges. The common-cathode configuration simplifies connection between battery positive and load rail, with anodes tied to each battery terminal. Thermal resistance of 1.5 °C/W per diode ensures safe operation even during sustained 20 A reverse-blocking conditions.
