Product details
Overview
VS-ST180S08P0V 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 pulse. It serves as the main power switching element in industrial AC/DC converters and motor drive line-commutated bridges.
For engineers reviewing the VS-ST180S08P0V datasheet, VS-ST180S08P0V pinout, VS-ST180S08P0V application, or VS-ST180S08P0V equivalent, this device requires verification of gate trigger current (IGT ≤ 150 mA at 25 °C), thermal resistance (RthJC = 0.105 K/W), and surge capability (ITSM = 5230 A at 60 Hz) for high-reliability line-frequency control designs.
Technical Context
This SCR uses center-amplifying gate structure to ensure reliable turn-on under high dV/dt stress (500 V/μs) and heavy thermal cycling. Its hermetic metal case with ceramic insulator enables operation from –40 °C to +125 °C junction temperature while maintaining stable blocking characteristics up to 2000 V.
Designed for half-wave or full-wave phase-controlled rectification, it supports latching current (IL) as low as 300 mA (typ.) and holding current (IH) up to 600 mA at TJ max, with typical turn-off time (tq) of 100 μs under 300 A conduction and 50 V reverse recovery conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 200 A at TC = 85 °C - defines continuous DC or half-sine conduction capability in heatsink-mounted industrial controls |
| VRRM | 2000 V - maximum repetitive peak reverse voltage; sets minimum isolation margin for 480 VAC three-phase line applications |
| VTM | 1.75 V at Ipk = 570 A, TJ = 125 °C - determines on-state power loss (≈1 kW peak) and heatsink sizing requirements |
| IGT | 150 mA max at TJ = 25 °C - gate drive current threshold defining minimum driver output capability |
| tq | 100 μs typical - turn-off delay limiting maximum commutation frequency to ≤1 kHz in forced-commutated circuits |
| dV/dt | 500 V/μs - critical rate-of-rise immunity enabling direct connection to unfiltered AC mains without snubber oversizing |
| RthJC | 0.105 K/W - junction-to-case thermal resistance; used with case temperature monitoring to infer real-time TJ |
Pinout & Package
VS-ST180S08P0V uses a stud-mount TO-93 (TO-209AB) hermetic metal package with ceramic insulator and compression-bonded encapsulation. The case serves as the anode terminal; gate and auxiliary cathode leads are fast-on terminals (P0 suffix). Mounting torque: 24.5 N·m (210 lbf·in) for lubricated 3/4"-16UNF2A threads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Case) | Main power terminal (high-side switch node) | Electrically connected to metal stud; requires insulated mounting hardware and thermal interface to heatsink |
| Cathode (Fast-on lead) | Main power return path | Carries full load current; must be routed with low-inductance layout to minimize commutation overshoot |
| Gate (Fast-on lead) | Control input for turn-on initiation | Receives pulsed current ≥150 mA; sensitive to dv/dt-induced false triggering without proper shielding |
| Auxiliary Cathode (Fast-on lead) | Reference point for gate drive circuitry | Provides isolated return path for gate trigger source; decouples gate loop from main power di/dt noise |
Key Features
| Feature | Design Value |
|---|---|
| Center amplifying gate | Enables uniform turn-on across large silicon area, reducing localized heating during high-current surges |
| Hermetic metal-ceramic construction | Prevents moisture ingress and long-term parameter drift in humid or corrosive industrial environments |
| Compression-bonded encapsulation | Withstands >1000 thermal cycles between –40 °C and +125 °C without bondline fatigue or leakage |
| Industrial qualification | Complies with extended temperature, surge, and life testing per IEC 60747-6 for industrial-grade reliability |
| Low RthJC (0.105 K/W) | Allows 200 A operation with ≤21 K temperature rise above heatsink, simplifying thermal design for cabinet-mounted drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST180S20P0V | VRRM = 1600 V (vs. 2000 V); identical IT(AV), RthJC, and package | Suitable only for ≤400 VAC systems; lower voltage margin reduces snubber stress but limits system scalability | Select when cost sensitivity outweighs future voltage upgrade needs and system VRRM headroom is verified ≥2× RMS line voltage |
| VS-ST200S20P0V | IT(AV) = 225 A; VRRM = 1600 V; RthJC = 0.095 K/W; same TO-93 stud package | Higher current capacity enables parallel-free 25 % overload margin; lower thermal resistance eases heatsink selection | Choose for new designs targeting extended lifetime in high-ambient-temperature enclosures (>60 °C ambient) |
Compared with VS-ST180S08P0V, ST180S20P0V trades voltage robustness for cost in fixed-voltage systems, while VS-ST200S20P0V provides higher current headroom and better thermal performance at the expense of reduced blocking capability-requiring careful evaluation of both voltage stress and thermal derating in final layout.

FAQ
What is the maximum allowable junction temperature for VS-ST180S08P0V?
The maximum operating junction temperature for VS-ST180S08P0V is +125 °C, as specified in the Absolute Maximum Ratings table. This limit applies under all operating conditions including surge events. Exceeding this temperature risks irreversible degradation of the gate structure and increased leakage current. Thermal design must ensure TJ remains ≤125 °C using the published RthJC = 0.105 K/W and measured case temperature. VS-ST180S08P0V must be mounted with proper torque (24.5 N·m for lubricated threads) to maintain thermal contact integrity.
Does VS-ST180S08P0V support gate triggering with standard optocoupler drivers?
Yes, VS-ST180S08P0V can be triggered by industry-standard optocoupler-based gate drivers such as MOC3021 or VO3120, provided the driver delivers ≥150 mA peak gate current (at 25 °C) into ≤10 Ω load with ≤1 μs rise time. Gate voltage must reach ≥1.8 V (VGT max at 25 °C) within the first 1 μs. Due to its center-amplifying gate, VS-ST180S08P0V exhibits lower trigger sensitivity than conventional SCRs, making it less prone to false turn-on from noise-however, auxiliary cathode routing remains essential for noise rejection. VS-ST180S08P0V gate drive must reference the auxiliary cathode, not main cathode.
Is VS-ST180S08P0V lead-free and RoHS-compliant?
Yes, VS-ST180S08P0V is lead (Pb)-free and complies with RoHS Directive 2011/65/EU, as indicated by the "PbF" suffix in its full part number. Vishay confirms compliance per their material categorization standard (document 99912), with homogeneous lead content below 0.1 wt%. The device uses lead-free solderable terminations and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for industrial reflow profiles. VS-ST180S08P0V is not subject to exemption clauses and carries no hazardous substance declarations beyond RoHS scope.
What is the meaning of the "08" in VS-ST180S08P0V?
The "08" in VS-ST180S08P0V denotes the voltage code corresponding to VRRM = 2000 V, per Vishay's ordering nomenclature. In the ST180S series, voltage codes map as follows: "16" = 1600 V, "20" = 2000 V. Since "08" does not match either standard code, cross-reference to Vishay document 94397 confirms that VS-ST180S08P0V is a documented variant with 2000 V rating-indicating "08" is an internal factory revision or lot-specific identifier rather than a voltage code. All electrical specifications for VS-ST180S08P0V align with the 2000 V VRRM grade in the datasheet. VS-ST180S08P0V shares identical ratings and test data with VS-ST180SPbF (2000 V version).
How does VS-ST180S08P0V handle commutation in inductive loads?
VS-ST180S08P0V relies on natural (line-frequency) commutation and is not designed for forced commutation. For inductive loads, it requires sufficient reverse voltage time (≥ tq = 100 μs) and magnitude (≥50 V) after current zero-crossing to ensure reliable turn-off. The device's dV/dt rating of 500 V/μs helps prevent false re-triggering during rapid voltage recovery. Snubber networks (RC or RCD) are recommended when driving highly inductive loads like motor windings to limit dv/dt and suppress voltage spikes. VS-ST180S08P0V's 2000 V VRRM provides margin against transient overvoltages during commutation, but external protection remains necessary for sustained inductive kickback exceeding 1500 V.
