Product details
Overview
VT3080S-E3 from Vishay General Semiconductor is a Trench MOS Barrier Schottky rectifier in TO-220AB package, rated for 80 V reverse voltage and 30 A average forward current, with ultra-low 0.39 V forward voltage at 5 A and 125 °C junction temperature-ideal for high-efficiency DC/DC converters and reverse battery protection circuits.
For engineers reviewing the VT3080S-E3 datasheet, VT3080S-E3 pinout, VT3080S-E3 application, or VT3080S-E3 equivalent, key selection criteria include its 0.73 V VF at 30 A, 200 A surge rating, 1.5 °C/W junction-to-case thermal resistance, RoHS-compliant matte tin plating, and J-STD-020 MSL Level 1 qualification.
Technical Context
This device employs trench MOS Schottky technology to achieve lower forward voltage and reduced switching losses versus planar Schottky diodes. Its single-die configuration supports unidirectional conduction with cathode-anode polarity marked on case, optimized for high-frequency operation up to several hundred kHz.
The TO-220AB package provides direct heatsink mounting (10 in-lbs max torque) and enables efficient thermal management in power supply freewheeling paths. It meets UL 94 V-0 flammability and passes JESD 201 Class 1A whisker testing.

Applications
| High-Frequency DC/DC Converters | Reverse Battery Protection |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 300 kHz–1 MHz isolated flyback or LLC converters delivering 12 V/20 A. IC Role / Device Role / Timing Role: Freewheeling Schottky rectifier replacing body diode of synchronous MOSFET to reduce conduction loss. Use Value: 0.39 V VF at 5 A and 125 °C enables ≥0.8 W reduction in rectifier loss versus legacy 0.55 V diodes. | Use Scenario: Input protection for 24 V vehicle infotainment systems against accidental reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between battery terminal and system input rail. Use Value: 80 V VRRM and 200 A IFSM withstand jump-start transients while 1.5 °C/W RθJC prevents thermal runaway during sustained reverse fault. |
| OR-ing Diode in Redundant Power Supplies | Switching Power Supply Output Rectification |
Use Scenario: Dual 48 V/15 A AC/DC outputs feeding parallel-connected server PSUs with automatic load sharing. IC Role / Device Role / Timing Role: High-current OR-ing diode ensuring seamless switchover and preventing backfeed between supplies. Use Value: Low 0.73 V VF at 30 A minimizes voltage drop across diode, preserving output regulation margin and reducing heat sink size. | Use Scenario: Output rectification in 500 W telecom rectifier with 54 V nominal output and 10 A load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG-TR | 100 V VRRM, 30 A IF(AV), VF = 0.75 V @ 30 A, TO-220AC package (non-isolated tab) | Higher voltage rating suits 48 V systems with wider transient margins; non-isolated tab requires insulator kit | Select when 100 V blocking is required and cathode isolation is not needed |
| ON Semi MBR30H100CT | 100 V VRRM, dual common-cathode configuration, VF = 0.78 V @ 30 A, TO-220AB package | Dual-diode layout supports center-tapped transformer or dual-rail designs; higher VF increases conduction loss | Choose for dual-output or transformer-based topologies where shared cathode simplifies layout |
Compared with STPS30H100CG-TR and MBR30H100CT, VT3080S-E3 offers lower 80 V VRRM with tighter voltage margin but superior 0.39 V VF at 5 A/125 °C and isolated TO-220AB tab-making it optimal for cost-sensitive, thermally constrained 24–48 V DC/DC and battery-protection applications where 100 V rating is unnecessary.

FAQ
What is the maximum junction temperature rating for VT3080S-E3?
The VT3080S-E3 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay's datasheet revision 26-Jun-2023. This rating enables reliable operation in under-hood automotive modules and enclosed industrial power supplies where ambient temperatures exceed 85 °C. Derating curves in Figure 1 confirm 30 A IF(AV) is maintainable up to 75 °C case temperature with appropriate heatsinking.
Does VT3080S-E3 have an electrically isolated heatsink tab?
Yes, VT3080S-E3 in TO-220AB package features an electrically isolated heatsink tab internally connected to the cathode (Pin 2). This eliminates the need for insulating washers or pads when mounting to a grounded chassis-unlike non-isolated variants such as TO-220AC. The isolation withstands 1500 VAC (1 min) per ITO-220AB test data, though VT3080S-E3 itself uses TO-220AB with equivalent isolation structure.
What is the forward voltage of VT3080S-E3 at 30 A and 25 °C?
The forward voltage (VF) of VT3080S-E3 is specified as 0.82 V (typical) and 0.95 V (maximum) at IF = 30 A and TA = 25 °C, per Electrical Characteristics table on page 2 of Vishay document 89169. At elevated temperature (125 °C), VF drops to 0.73 V (typical), reflecting the negative temperature coefficient typical of Schottky devices.
Is VT3080S-E3 RoHS-compliant and lead-free?
Yes, VT3080S-E3 is RoHS-compliant and lead-free, indicated by the "E3" suffix per Vishay's ordering nomenclature. The terminals are matte tin plated and qualified to J-STD-002 for solderability and JESD 201 Class 1A for whisker resistance-ensuring compatibility with lead-free reflow processes and long-term reliability in harsh thermal environments.
What packaging format is supplied for VT3080S-E3?
VT3080S-E3 is supplied in tube packaging with a base quantity of 50 units per tube and package code "4W", as confirmed in the Ordering Information table on page 2 of Vishay document 89169. This format supports manual and semi-automated insertion in low-to-medium volume production, and is distinct from tape-and-reel variants used for surface-mount equivalents like VBT3080S-E3/8W.
