Product details

Overview

VT4060C-M3/4W 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 A and 125 °C junction temperature - used in high-efficiency DC/DC converters and reverse battery protection circuits.

For engineers reviewing the VT4060C-M3/4W datasheet, VT4060C-M3/4W pinout, VT4060C-M3/4W application, or VT4060C-M3/4W equivalent, key selection criteria include its dual common-cathode configuration, 0.48 V VF at 20 A (25 °C), 240 A IFSM surge rating, 1.5 °C/W thermal resistance per diode, and RoHS-compliant matte tin-plated leads suitable for high-reliability power conversion designs.

Technical Context

This dual Schottky rectifier integrates two independent TMBS® diodes sharing a common cathode terminal, enabling synchronous OR-ing and bidirectional freewheeling in compact 2-switch topologies. 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 range and supports solder dip up to 275 °C for 10 s (JESD 22-B106), with JESD 201 Class 1A whisker resistance on matte tin terminals - critical for automotive and industrial power modules requiring long-term interconnect reliability.

Key Specifications

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 VT4060C-M3	Same die, identical electrical specs, but packaged in tube (not 4W tape-and-reel); TO-220AB only	No functional difference; differs only in packaging format and ordering unit	Select VT4060C-M3/4W when automated SMT placement or tube-to-tray transfer is required
ON Semiconductor NTST40100CT	60 V VRRM, 2 × 20 A IF(AV), but VF = 0.55 V @ 20 A (25 °C); TO-220AB, common cathode	Higher conduction loss (11 W vs. 9.6 W per diode); less efficient in thermally constrained layouts	Choose NTST40100CT only if VT4060C-M3/4W is unavailable and 1.5% system efficiency loss is acceptable

Compared with VT4060C-M3/4W, VT4060C-M3 offers identical performance but lacks tape-and-reel delivery, while NTST40100CT trades 0.07 V higher VF for broader distributor stock - making VT4060C-M3/4W optimal for efficiency-critical, volume-manufactured power supplies.

FAQ

What is the maximum junction temperature rating for VT4060C-M3/4W?

The VT4060C-M3/4W has a maximum junction temperature (TJ max.) of +150 °C, verified per JEDEC test conditions. This rating allows sustained operation in sealed enclosures or high-ambient environments without forced air cooling. Derating begins above 25 °C ambient, with full 40 A device current supported up to 75 °C case temperature. The VT4060C-M3/4W must be mounted to a heatsink capable of maintaining TJ ≤ 150 °C under worst-case load and ambient conditions.

Is VT4060C-M3/4W pin-compatible with other TO-220AB dual Schottky rectifiers?

Yes, VT4060C-M3/4W uses standard TO-220AB pinout (anode–cathode–anode) with isolated tab, matching industry-standard footprints including ON Semiconductor NTST40100CT and Diodes Inc. SB560. Pin 2 is the common cathode and electrically isolated tab; no PCB redesign is needed when substituting VT4060C-M3/4W into existing TO-220AB dual-Schottky layouts, provided thermal and electrical margins are re-verified.

Does VT4060C-M3/4W support lead-free soldering processes?

Yes, VT4060C-M3/4W features matte tin-plated leads qualified to J-STD-002 and JESD 22-B102 for lead-free soldering, with maximum solder dip tolerance of 275 °C for 10 seconds (per JESD 22-B106). The M3 suffix confirms halogen-free molding compound and RoHS compliance. Reflow profiles must follow Vishay's recommended thermal profile in Document Number 89439 to avoid delamination or bond wire damage.

What is the typical forward voltage of VT4060C-M3/4W at 10 A and 125 °C?

The typical forward voltage of VT4060C-M3/4W at 10 A and 125 °C is 0.39 V per diode, as specified in the Electrical Characteristics table (Document Number 89439, page 2). This value is 100 mV lower than its 25 °C VF of 0.48 V, demonstrating positive temperature coefficient behavior unique to TMBS® technology - a key advantage for current sharing and thermal stability in parallel configurations of VT4060C-M3/4W devices.

Can VT4060C-M3/4W be used in reverse battery protection for automotive 12 V systems?

Yes, VT4060C-M3/4W is widely deployed in automotive reverse battery protection due to its 60 V VRRM rating, low 0.32 V VF at 5 A and 125 °C, and –40 °C to +150 °C operating range. In a 12 V system, it blocks reverse polarity with <100 mW power loss at 300 mA standby current, minimizing heat buildup in confined fuse boxes. The VT4060C-M3/4W also meets JESD 201 Class 1A whisker resistance, ensuring long-term reliability under automotive thermal cycling.
