Product details
Overview
VS-ST180S04P1VPBF from Vishay Semiconductors is a phase-control thyristor (SCR) in stud-mount TO-93 (TO-209AB) metal-ceramic package, rated for 200 A average on-state current at 85 °C case temperature, 2000 V repetitive peak off-state voltage (VRRM), and 1.75 V maximum on-state voltage at 570 A peak. It features center-amplifying gate, hermetic sealing, and compression-bonded encapsulation for industrial-grade thermal cycling resilience, used in high-power AC controllers and DC motor drives.
For engineers reviewing the VS-ST180S04P1VPBF datasheet, VS-ST180S04P1VPBF pinout, VS-ST180S04P1VPBF application, or VS-ST180S04P1VPBF equivalent, this page delivers verified electrical ratings (IT(AV) = 200 A, VRRM = 2000 V, tq = 100 μs, IGT = 150 mA at TJ = 25 °C, RthJC = 0.105 K/W), thermal behavior under sinusoidal conduction, and EOL-aware alternative guidance per Vishay's official notice.
Technical Context
This single SCR operates as a line-synchronized, gate-triggered power switch with latching behavior. Its center-amplifying gate structure enables reliable turn-on at low dIg/dt (1 A/μs) and supports robust triggering across -40 °C to +125 °C junction temperature range, with typical delay time td = 1.0 μs and turn-off time tq = 100 μs under specified test conditions.
Designed for heavy-duty industrial operation, it withstands non-repetitive surge currents up to 5230 A (60 Hz, 8.3 ms), delivers I²t rating of 114 kA²s (60 Hz), and maintains critical dV/dt immunity of 500 V/μs at TJ max - all enabled by hermetic metal case with ceramic insulator and compression-bonded construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 200 A at TC = 85 °C - defines continuous DC or half-sine load capability without heatsink derating beyond thermal limits |
| VRRM | 2000 V - maximum repetitive peak reverse voltage; determines minimum isolation margin in 400–480 VAC line applications |
| VTM | 1.75 V at ITM = 570 A, TJ = 125 °C - sets conduction loss baseline for thermal design of heatsink and cooling system |
| IGT | 150 mA at TJ = 25 °C - gate trigger current threshold defining minimum driver strength required for reliable turn-on |
| tq | 100 μs - typical turn-off time; constrains maximum operating frequency in phase-controlled rectifiers and inverters |
| RthJC | 0.105 K/W (DC) - junction-to-case thermal resistance; enables direct calculation of ΔTJ from measured case temperature |
| dV/dt | 500 V/μs - critical rate-of-rise immunity; determines snubber requirements to prevent false triggering in noisy AC environments |
Pinout & Package
VS-ST180S04P1VPBF uses TO-93 (TO-209AB) stud-mount metal-ceramic package with three terminals: anode (stud base), cathode (fast-on terminal), and gate (fast-on terminal). The anode serves as both power terminal and mechanical mounting interface via 3/4"-16UNF2A threaded stud. Hermetic construction ensures long-term reliability under thermal cycling and humidity exposure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Main power input / high-side switching node | Electrically and thermally coupled to heatsink; requires insulated mounting hardware and torque control (24.5 N·m lubricated) |
| Cathode (Fast-on) | Main power return / low-side reference | Carries full load current; must be routed with low-inductance path to minimize commutation stress |
| Gate (Fast-on) | Control input for turn-on initiation | Receives pulsed trigger signal; sensitive to dIg/dt and noise; requires localized decoupling and gate resistor selection per Fig. 9 load lines |
Key Features
| Feature | Design Value |
|---|---|
| Center-amplifying gate | Reduces required gate drive energy and improves turn-on consistency across temperature and aging, enabling simpler gate drivers |
| Hermetic metal-ceramic case | Eliminates moisture ingress and internal corrosion risk over 20+ years in industrial environments with condensation or chemical exposure |
| Compression-bonded encapsulation | Withstands >1000 thermal cycles between -40 °C and +125 °C without bondline degradation or parameter drift |
| Industrial qualification | Meets extended temperature (-40 °C to +125 °C), surge (5230 A), and dV/dt (500 V/μs) requirements for factory automation and power conversion systems |
| Stud-mount mechanical interface | Enables direct bolt-down to liquid-cooled or finned heatsinks with repeatable thermal contact and mechanical stability under vibration |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST180S20PbF | VRRM = 1600 V (vs. 2000 V); identical IT(AV), package, and thermal specs | Suitable for 380–400 VAC systems where lower voltage margin is acceptable | Select when system peak line voltage remains ≤1414 V and cost sensitivity outweighs extra voltage headroom |
| VS-ST200S04P1VPBF | IT(AV) = 220 A, VRRM = 2000 V, RthJC = 0.095 K/W - higher current rating and improved thermal resistance | Supports higher continuous loads or reduced heatsink size in new designs | Choose for future-proofing or upgrade paths where layout space allows same stud footprint but higher power density is needed |

FAQ
What is the maximum allowable case temperature for continuous operation of VS-ST180S04P1VPBF?
The maximum allowable case temperature for VS-ST180S04P1VPBF is 85 °C when delivering its rated 200 A average on-state current. This limit is defined in the Absolute Maximum Ratings table and corresponds to DC or 180° conduction-angle operation. Exceeding this temperature requires derating per Fig. 1 and Fig. 2 in the datasheet, which show allowable current reduction at higher case temperatures.
Does VS-ST180S04P1VPBF support gate triggering at elevated junction temperatures?
Yes, VS-ST180S04P1VPBF supports gate triggering across its full junction temperature range of -40 °C to +125 °C. At TJ = 125 °C, the maximum required gate trigger current (IGT) drops to 40 mA, and gate trigger voltage (VGT) reduces to 1.2 V - confirming improved gate sensitivity at high temperature, a key feature of its center-amplifying gate design.
What is the recommended gate drive circuit for VS-ST180S04P1VPBF in a 60 Hz AC controller?
For 60 Hz AC line synchronization, the recommended gate drive for VS-ST180S04P1VPBF uses a 20 V pulse with ≤10 Ω series resistance and rise time tr ≤ 1 μs, per the dI/dt test condition. This matches Fig. 9 load line (b) and ensures reliable turn-on while staying within PGM = 10 W (tp ≤ 5 ms) and IGM = 3.0 A absolute maximum ratings.
How does the thermal resistance RthJC of VS-ST180S04P1VPBF change with conduction angle?
VS-ST180S04P1VPBF's RthJC increases as conduction angle decreases: from 0.105 K/W at DC/180° to 0.060 K/W at 30° sinusoidal conduction (per ΔRthJC Conduction Table). This reflects reduced average power dissipation at narrow firing angles, allowing higher transient current handling without exceeding junction temperature limits.
Is VS-ST180S04P1VPBF lead-free and RoHS compliant?
Yes, VS-ST180S04P1VPBF is lead (Pb)-free and RoHS compliant, as indicated by the "PbF" suffix in its ordering code and confirmed in Vishay's material categorization documentation (www.vishay.com/doc?99912). It meets EU RoHS Directive 2011/65/EU and associated amendments for hazardous substance restrictions.
