Product details
Overview
VBT4060C-E3/8W from Vishay General Semiconductor is a dual common-cathode Trench MOS Barrier Schottky rectifier in D2PAK (TO-263AB) package, rated for 60 V reverse voltage, 2 × 20 A average forward current per diode, and 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.
For engineers reviewing the VBT4060C-E3/8W datasheet, VBT4060C-E3/8W pinout, VBT4060C-E3/8W application, or VBT4060C-E3/8W equivalent, key selection criteria include its dual common-cathode configuration, 240 A surge rating, 1.5 °C/W junction-to-case thermal resistance per diode, and MSL Level 1 qualification for surface-mount reflow compatibility.
Technical Context
This device implements trench MOS Schottky architecture to achieve lower VF and higher efficiency than planar Schottky or standard PN rectifiers. Its dual-diode common-cathode topology enables compact OR-ing and synchronous rectification layouts in space-constrained power stages.
Rated for continuous operation up to 150 °C junction temperature and qualified to J-STD-020 MSL Level 1 (245 °C peak reflow), the VBT4060C-E3/8W supports high-reliability industrial and automotive-grade power supplies where low conduction loss and thermal robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum repetitive reverse blocking voltage per diode; defines safe operating range in 48 V and 36 V bus systems |
| IF(AV) per diode | 20 A - average forward current per diode at TC = 110 °C; supports 40 A total device output with shared cathode |
| VF @ 5 A, 125 °C | 0.32 V - ultra-low forward drop enabling >95 % efficiency in low-voltage, high-current DC/DC stages |
| IFSM | 240 A - non-repetitive surge rating; withstands inrush and fault currents in SMPS primary-side freewheeling |
| RθJC per diode | 1.5 °C/W - thermal resistance from junction to case; enables direct heatsink mounting for high-power dissipation |
| dV/dt | 10,000 V/μs - high voltage transient immunity; reduces risk of false turn-on in fast-switching topologies |
Pinout & Package
Package: D2PAK (TO-263AB), surface-mount, single-row 3-terminal outline with exposed metal tab (cathode connection and thermal path). Mounting torque ≤ 10 in-lbs; not recommended for bottom-side wave soldering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VBT4060C-E3/4W | Same die and electrical specs; differs only in packaging - tube delivery (50 pcs) vs. tape-and-reel (800 pcs) | No functional difference; selected based on production volume and SMT line feed requirements | Choose VBT4060C-E3/8W for automated pick-and-place; choose VBT4060C-E3/4W for prototyping or low-volume hand assembly |
| SS8060CT | 60 V, 2 × 20 A dual common-cathode Schottky; VF = 0.55 V @ 20 A (25 °C), RθJC = 2.0 °C/W | Higher VF and thermal resistance reduce efficiency in thermally constrained designs above 85 °C ambient | Select SS8060CT only if cost sensitivity outweighs efficiency and thermal performance requirements |
Compared with VBT4060C-E3/8W, the VBT4060C-E3/4W offers identical performance in tube packaging, while SS8060CT trades 0.07 V higher VF and +0.5 °C/W worse thermal resistance for broader distributor availability - making VBT4060C-E3/8W optimal for high-density, thermally demanding power stages.

FAQ
What is the maximum junction temperature rating for the VBT4060C-E3/8W?
The VBT4060C-E3/8W has a maximum junction temperature (TJ max.) of +150 °C, verified per datasheet revision 02-Jul-2018. This rating allows continuous operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies when mounted to an adequate heatsink. Thermal design must respect the 1.5 °C/W RθJC per diode to avoid exceeding this limit under full load.
Does the VBT4060C-E3/8W support lead-free reflow soldering?
Yes, the VBT4060C-E3/8W is qualified to MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 245 °C, making it fully compatible with standard lead-free reflow profiles. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the E3 suffix confirms compliance with JESD 201 Class 1A whisker testing.
What does the "-E3/8W" suffix indicate in VBT4060C-E3/8W?
The "-E3" denotes RoHS-compliant, commercial-grade construction with matte tin plating and JESD 201 Class 1A whisker resistance. The "/8W" specifies tape-and-reel packaging: 800 devices per reel, using Vishay's standard 8W carrier tape format - optimized for high-speed SMT placement lines. This differs from the /4W variant, which ships in tubes of 50.
Can the VBT4060C-E3/8W be used in reverse battery protection for 24 V systems?
Yes, the VBT4060C-E3/8W is routinely deployed in 24 V reverse battery protection due to its 60 V VRRM rating and low 0.48 V forward voltage at 20 A. Its common-cathode dual configuration allows series insertion in the positive rail with minimal voltage drop, preserving system efficiency. At 125 °C, VF drops to 0.48 V - ensuring stable performance even under under-hood thermal conditions.
Is the heatsink tab of the VBT4060C-E3/8W electrically isolated?
No, the exposed metal tab on the VBT4060C-E3/8W is the common cathode terminal and is electrically connected to Pin 1 and Pin 2 cathodes. It must be routed to the same net as the output/common return path. Electrical isolation requires external insulation (e.g., mica washer or thermal pad with dielectric layer), and mounting torque must not exceed 10 in-lbs to avoid package damage.
