VS-P105W Présentation
A power module is a packaged assembly of two or more discrete power semiconductors (thyristors, diodes, MOSFETs, IGBTs) integrated into a single isolated, base-plate-cooled housing. Compared with discrete through-hole TO-220/TO-247 designs, a power module simplifies mechanical assembly, eliminates individual insulator pads, and provides a uniform thermal interface for a single heatsink. Within the broader taxonomy, the VS-P105W sits in the SCR module branch of thyristors, which itself belongs to the discrete semiconductor family of power management components.
Key features of the VS-P105W include glass-passivated junctions for long-term reliability, an electrically isolated base plate (2500 V RMS isolation typical), high dv/dt dynamic characteristics, and a wide voltage range up to 1200 V VRRM/VDRM. The PACE-PAK package combines a robust mechanical housing with convenient screw-type power terminals, simplifying both PCB-free power conversion and thermal management.
The integrated bridge topology makes the VS-P105W suitable for AC-DC controlled rectification, soft-start circuits, and motor phase control. The 1200 V rating provides ample margin for 480 V three-phase rectified bus operation, and the 25 A continuous current supports kilowatt-class industrial loads. The 357 A surge rating absorbs inrush during motor startup and transformer energization.
Typical applications include industrial motor drives, welding power supplies, battery chargers, UPS input rectifiers, temperature-controlled heating, and large DC power supplies. The isolated base plate allows direct mounting to a chassis or heatsink without additional insulating hardware.
When designing with the VS-P105W, ensure the heatsink thermal resistance is sized to keep the junction below 125 C under worst-case load. Mount torque on the power terminals must follow the datasheet specification to avoid thermal cycling fatigue, and a properly rated snubber or MOV is recommended for inductive loads.

Applications typiques
VS-P105W convient pour 6 applications: Industrial AC Motor Soft-Start, Welding Power Supply Primary Rectifier, Battery Charger Controlled Rectifier, UPS Input Rectifier Stage, Temperature-Controlled Heating (Industrial Furnace), Large DC Power Supply for Electroplating.
Industrial AC Motor Soft-Start
The VS-P105W fits AC motor soft-start circuits where phase-angle control limits inrush current. The 25 A average on-state current (IT(AV)) handles fractional-horsepower three-phase motor phases when used in a three-module bank, while the 357 A surge rating (ITSM at 50 Hz) absorbs locked-rotor inrush. The 1200 V VDRM rating provides safe margin for 480 V AC line-to-line rectified buses. Placed in series with each AC mains feed, the SCRs are gated with a ramped firing angle to gradually apply voltage, reducing mechanical torque shock and line-side current spikes. The isolated PACE-PAK base plate mounts directly to a chassis heatsink without additional insulators, simplifying mechanical assembly in motor control cabinets.

Welding Power Supply Primary Rectifier
Welding inverter front-ends require a robust controlled rectifier that can deliver high average current and absorb repetitive surge transients from the welding transformer. The VS-P105W with 25 A IT(AV) and 357 A ITSM rating meets the primary-side rectified current demand for sub-15 kVA welding sets when configured in a full-wave bridge. Glass-passivated junctions provide long-term thermal-cycling reliability, and the 1200 V VDRM handles the reflected secondary transients common in transformer-coupled welders. The integrated 2-SCR + 2-diode bridge simplifies gate-drive design compared with discrete SCR assemblies, reducing BOM count and improving firing symmetry.
Recommandé
Battery Charger Controlled Rectifier
Industrial battery chargers for forklift, traction, and stationary backup batteries use phase-controlled rectifiers to regulate charging current. The VS-P105W provides the controlled half of an AC-DC bridge: the SCRs vary the DC output voltage while internal diodes complete the return path. With 25 A continuous rating, a single module supports chargers up to approximately 3 kW at 120 V DC bus. The 1200 V rating tolerates 480 V AC mains transients, and the PACE-PAK chassis-mount housing simplifies cabinet wiring. The 60 mA maximum gate trigger current (IGT) allows direct interfacing with typical analog or digital firing-control circuits without auxiliary gate-driver stages.
Recommandé
UPS Input Rectifier Stage
Uninterruptible power supplies often include a controlled input rectifier for power-factor correction and inrush limiting. The VS-P105W is suitable for the controlled-rectifier stage in small-to-medium UPS systems up to approximately 5 kVA. The 25 A average current handles the continuous battery-charging bus, while the 357 A surge rating covers the initial bus capacitor charging transient when the UPS transfers from bypass to inverter. Glass-passivated junctions and the isolated PACE-PAK base plate deliver the long-term reliability required for always-on UPS installations in data centers and medical facilities.
Recommandé
Temperature-Controlled Heating (Industrial Furnace)
Resistance-heating furnaces and large oven banks use phase-angle SCR control for precise temperature regulation. The VS-P105W delivers 25 A continuous to a heating load with the SCRs gated by a temperature-loop-derived firing angle, achieving smooth proportional power control without the wear of mechanical contactors. The 1200 V rating handles 480 V AC mains, and the 357 A ITSM rating tolerates cold-element inrush when a furnace is first energized. The integrated 2-SCR + 2-diode bridge configuration directly supports full-wave AC control without additional discrete diodes, reducing panel wiring complexity.
Recommandé
Large DC Power Supply for Electroplating
Electroplating and electrolysis rectifiers require high-current low-voltage DC outputs with adjustable magnitude for process control. The VS-P105W in a bridge configuration provides a controllable DC output up to 25 A average, ideal for small-to-medium plating cells. The 1200 V VDRM safely handles 480 V AC three-phase rectified inputs, and the isolated PACE-PAK base plate allows multiple modules to be mounted on a common heatsink or chassis without additional insulating hardware. Gate-trigger symmetry between the two SCRs (60 mA IGT) ensures balanced current sharing and minimizes DC ripple at low firing angles.

Notes de conception
Estimated: at 25 A continuous conduction with ~1.4 V on-state drop per conducting leg, the VS-P105W dissipates approximately 35 W. Using the PACE-PAK junction-to-base-plate thermal resistance and a 75 C base-plate target, the heatsink-to-ambient resistance must be below roughly 1.4 C/W. Above 18 A continuous, forced-air cooling is recommended. Mount the module on a flat machined heatsink surface with thermal compound; torque per the datasheet to avoid thermal fatigue.
The VS-P105W PACE-PAK base plate is electrically isolated, but the screw-type power terminals still require careful wiring layout. Keep the gate/cathode control wiring physically separated from the AC power cabling to prevent dv/dt-induced false triggering; gate-cathode loop area should be minimized and a small resistor (100-330 ohm) in series with the gate is recommended. According to Vishay application notes, twisted-pair gate leads further improve noise immunity in industrial environments.
Do not exceed VDRM/VRRM during commutation - the VS-P105W can be subjected to voltage transients above 1200 V if the AC line has poor surge protection. Add an MOV or RC snubber across each SCR pair for inductive loads (motors, transformers). Confirm gate pulse width is greater than 20 microseconds to ensure full SCR turn-on; narrow pulses may leave the device in partial conduction and cause excessive heating. Always observe proper heatsink mounting torque to maintain thermal performance over thermal cycling.
