Product details
Overview
VS-80EPS12PBF from Vishay is a high-voltage, standard-recovery silicon rectifier diode in TO-247AC package, rated for 80 A average forward current, 1200 V peak reverse voltage (VRRM), and 1.17 V forward voltage drop at 80 A and 25 °C. It operates up to 150 °C junction temperature and is optimized for industrial input rectification in high-power AC/DC converters.
For engineers reviewing the VS-80EPS12PBF datasheet, VS-80EPS12PBF pinout, VS-80EPS12PBF application, or VS-80EPS12PBF equivalent, key selection criteria include its 1450 A non-repetitive surge rating, 0.35 °C/W junction-to-case thermal resistance, low forward slope resistance (3.17 mΩ at 150 °C), and compatibility with Vishay HPP switch and output rectifier families in identical outlines.
Technical Context
This device is a single-anode, single-cathode standard recovery rectifier-distinct from fast or ultrafast types-designed for line-frequency (50/60 Hz) input stage rectification where moderate switching speed and low conduction loss are prioritized over reverse recovery time. Its glass-passivated PN junction ensures stable operation under sustained thermal stress.
The TO-247AC package features three terminals: anode (pins 1 & 4), cathode (pin 3), and electrically isolated metal base (pin 2), enabling direct heatsink mounting with 0.2 °C/W typical case-to-heatsink thermal resistance when greased and torqued to 6–12 kgf·cm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V maximum peak reverse voltage - supports 800 V RMS AC inputs with safety margin for transient overvoltage in industrial mains-fed supplies |
| IF(AV) | 80 A average forward current at TC = 100 °C - enables continuous conduction in high-power SMPS and UPS front-ends |
| VF @ 80 A | 1.17 V at TJ = 25 °C - minimizes conduction loss and heat generation during steady-state operation |
| IFSM | 1450 A non-repetitive surge (10 ms sine pulse, rated VRRM applied) - withstands inrush currents during cold-start of large capacitive-input rectifiers |
| RthJC | 0.35 °C/W junction-to-case - allows efficient thermal transfer to heatsink, supporting >100 W dissipation at ΔT = 35 °C |
| TJ Range | -40 to +150 °C - qualified for industrial environments without derating below 100 °C case temperature |
Pinout & Package
Package: TO-247AC (JEDEC), 3-terminal through-hole outline with isolated metal base for heatsink attachment. Anode and cathode leads are electrically separated from the base.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode (pin 3) | DC output connection point | Single cathode terminal simplifies PCB routing to bulk capacitor or downstream converter stage |
| Base (pin 2) | Electrically isolated heatsink interface | Enables direct mechanical mounting to heatsink without insulating washer; thermally conductive but electrically floating |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Ensures long-term reliability and leakage stability at 150 °C junction temperature, critical for unattended industrial operation |
| Low VF slope resistance | 3.17 mΩ at 150 °C - maintains low conduction loss even under thermal stress, reducing thermal runaway risk |
| High I²t rating | 10 500 A²s (10 ms, rated VRRM applied) - provides robust fuse coordination in upstream protection schemes |
| Lead (Pb)-free construction | RoHS-compliant finish (PbF suffix) meets global environmental compliance without sacrificing solderability or thermal performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8012W | 1200 V VRRM, 80 A IF(AV), TO-247 package, fast recovery (trr ≈ 125 ns) vs. standard recovery (no trr spec) | Better suited for higher-frequency PFC stages; higher VF (1.35 V) increases conduction loss | Select STTH8012W only if circuit requires faster switching; VS-80EPS12PBF preferred for pure line-frequency rectification |
| IXYS MUR880E | 800 V VRRM (not 1200 V), same IF(AV), TO-247AC, ultrafast recovery (trr ≈ 50 ns), VF = 1.25 V | Insufficient voltage margin for 400 VAC+ systems with transients; unsuitable for 1200 V design targets | MUR880E may be used only in lower-voltage legacy designs; VS-80EPS12PBF required where 1200 V rating is mandated |
Compared with STTH8012W and IXYS MUR880E, VS-80EPS12PBF delivers superior thermal robustness (150 °C TJ), lower VF, and guaranteed 1200 V capability-making it optimal for industrial rectifiers where efficiency and surge immunity outweigh switching speed needs.

FAQ
What is the maximum junction temperature rating for VS-80EPS12PBF?
The VS-80EPS12PBF is rated for a maximum junction temperature of +150 °C, verified per Vishay's industrial qualification standards. This allows uninterrupted operation in ambient temperatures up to 85 °C when properly heatsinked, with derating applied above TC = 100 °C per the datasheet's current rating curves. The glass passivation process ensures stable leakage and VF characteristics across this full range.
Does VS-80EPS12PBF have a specified reverse recovery time (trr)?
No, VS-80EPS12PBF is a standard recovery rectifier and does not specify reverse recovery time (trr) in its datasheet. It is intended for line-frequency (50/60 Hz) rectification-not high-frequency switching-so trr is not characterized. Engineers should avoid using VS-80EPS12PBF in circuits requiring fast recovery; alternative ultrafast or soft-recovery diodes must be selected for such applications.
What is the correct mounting torque for VS-80EPS12PBF's TO-247AC package?
The recommended mounting torque for VS-80EPS12PBF is 6–12 kgf·cm (5–10 lbf·in), applied to the center screw securing the TO-247AC base to the heatsink. Proper torque ensures optimal thermal contact (RthCS = 0.2 °C/W typical) while avoiding package deformation. Over-torquing may damage the internal die attach or lead frame; under-torquing increases thermal resistance and risks premature thermal failure.
Is VS-80EPS12PBF suitable for use in a full-bridge rectifier configuration?
Yes, VS-80EPS12PBF is commonly deployed in full-bridge rectifier configurations for high-power AC/DC conversion. Its 1200 V VRRM rating provides sufficient margin for 400 VAC 3-phase or 230 VAC single-phase inputs with transients. Each VS-80EPS12PBF handles one leg of the bridge, and the dual-anode (pins 1 & 4) layout supports low-inductance PCB routing in symmetric layouts.
How does the forward voltage drop of VS-80EPS12PBF vary with temperature?
The forward voltage drop of VS-80EPS12PBF decreases with rising junction temperature-characteristic of silicon PN junctions. At 80 A, VF drops from 1.17 V at 25 °C to approximately 0.95 V at 150 °C. This negative temperature coefficient must be considered in thermal design, as it reduces conduction loss at elevated temperatures but also affects current sharing in parallel configurations.
