Product details
Overview
VS-ST180S16M0L 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, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and 1.75 V maximum on-state voltage at 570 A pulse. It features center amplifying gate, hermetic sealing, and compression-bonded encapsulation for industrial-grade thermal cycling resilience, used in high-power AC/DC motor controllers and industrial rectifier systems.
For engineers reviewing the VS-ST180S16M0L datasheet, VS-ST180S16M0L pinout, VS-ST180S16M0L application, or VS-ST180S16M0L equivalent, key selection criteria include verified gate trigger current (150 mA max at 25 °C), turn-off time (100 μs typical), dV/dt immunity (500 V/μs), and thermal resistance (0.105 K/W junction-to-case), all critical for reliable operation in line-commutated converters and heavy-duty power control.
Technical Context
This SCR operates as a single-polarity, latching semiconductor switch with gate-controlled turn-on and natural commutation via current zero-crossing. Its design supports 180° conduction half-sine wave operation and withstands 5000 A non-repetitive surge (10 ms, 50 Hz) with I²t rating of 125 kA²s - enabling robust performance in high-inertia motor drives and welder primary controls.
Thermal management is defined by RthJC = 0.105 K/W (DC), increasing to 0.060 K/W at 30° conduction angle, and requires mechanical mounting with 24.5 N·m torque (lubricated 3/4"-16UNF-2A stud). Gate drive must meet PGM ≤ 10 W (5 ms) and VGT ≤ 3.0 V (25 °C) while avoiding false triggering (VGD ≤ 0.25 V, IGD ≤ 10 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 200 A at 85 °C case temperature - defines continuous DC or half-sine load capability without forced cooling |
| VDRM / VRRM | 1600 V - maximum repetitive peak off-state voltage; sets minimum isolation margin for 1150 V RMS AC line applications |
| VTM | 1.75 V at 570 A, 125 °C, 10 ms sine pulse - determines conduction loss and heatsink sizing under peak load |
| IGT | 150 mA max at 25 °C - gate current threshold defining minimum driver strength required for reliable turn-on |
| tq | 100 μs typical turn-off time - constrains maximum operating frequency and commutation circuit design |
| dV/dt | 500 V/μs critical rate-of-rise immunity - dictates snubber requirements to prevent false triggering during voltage transients |
| RthJC | 0.105 K/W (DC) - enables thermal modeling of junction temperature rise under steady-state conduction |
Pinout & Package
VS-ST180S16M0L uses a hermetically sealed TO-93 (TO-209AB) stud-mount metal-ceramic package with three terminals: anode (stud base), cathode (fast-on terminal), and gate (fast-on terminal). Mounting employs 3/4"-16UNF-2A threaded stud (lubricated torque: 24.5 N·m) and requires electrically insulated heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Main current input path | Electrically connected to metal case; must be isolated from heatsink via ceramic washer or mica insulator |
| Cathode (Fast-on) | Main current return path | Carries full load current; fast-on tab (0.25 mm thick) mates with 6.35 mm wide receptacle per UL 486A/B |
| Gate (Fast-on) | Control input for turn-on | Receives low-energy pulse (≤10 W, ≤5 ms); polarity-sensitive - positive relative to cathode only |
Key Features
| Feature | Design Value |
|---|---|
| Center amplifying gate | Reduces required gate drive energy by enhancing internal carrier injection - lowers IGT to 150 mA max at 25 °C |
| Hermetic metal-ceramic construction | Prevents moisture ingress and contamination over 20+ years in humid industrial environments - qualified per MIL-STD-750 Method 1071 |
| Compression-bonded encapsulation | Withstands ≥1000 thermal cycles (-40 °C to +125 °C) without delamination - essential for welding equipment and rolling mill drives |
| Industrial-level qualification | Rated for continuous operation from -40 °C to +125 °C junction temperature - meets IEC 60747-6 for power thyristors |
| High dI/dt immunity | 1000 A/μs non-repetitive rate-of-rise tolerance - enables direct connection to low-impedance transformer secondaries without added series inductance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST180S16-TR | Same die, TO-209AB stud package, but with eyelet terminals (not fast-on); RthJC identical; Pb-free status not specified | Requires different termination hardware (eyelet crimps vs. fast-on receptacles); compatible in same heatsink footprint | Select when legacy board interfaces use eyelet lugs or when Pb-free compliance is not mandated |
| VS-ST180S20M0L | Same package and construction, but rated for 2000 V VDRM/VRRM (vs. 1600 V); otherwise identical electrical/thermal specs | Suitable for 600 VAC+ systems (e.g., 690 VAC industrial grids); higher voltage margin increases snubber margin but raises cost | Select for applications requiring >1600 V blocking - e.g., medium-voltage drives or export markets with 600 VAC infrastructure |
Compared with VS-ST180S16M0L, ST180S16-TR offers identical power handling but different mechanical interface, while VS-ST180S20M0L extends voltage capability without altering thermal or gate drive behavior - enabling direct upgrade paths in existing layouts where voltage stress exceeds 1600 V.

FAQ
What is the maximum allowable junction temperature for VS-ST180S16M0L?
The maximum operating junction temperature for VS-ST180S16M0L 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 silicon die and gate oxide integrity. Thermal design must ensure TJ remains ≤125 °C using the documented RthJC = 0.105 K/W and appropriate heatsink selection. The VS-ST180S16M0L datasheet confirms this value across all conduction angles and pulse durations.
Does VS-ST180S16M0L support anti-parallel configuration for AC switching?
Yes, VS-ST180S16M0L is commonly used in anti-parallel pairs to implement bidirectional AC switching in static VAR compensators and solid-state contactors. Each device handles one half-cycle; the pair must share matched gate drive timing and thermal mounting to ensure balanced current sharing. The VS-ST180S16M0L's symmetric VDRM/VRRM (1600 V) and identical turn-on/turn-off characteristics make it suitable for such configurations when mounted on a common heatsink with electrical isolation.
What gate drive voltage and current are required to reliably trigger VS-ST180S16M0L?
VS-ST180S16M0L requires a gate trigger voltage ≤3.0 V and current ≤150 mA at 25 °C to guarantee turn-on across all units. Recommended drive uses 20 V with 10 Ω series resistance (per Fig. 9 load line), delivering ~2 A peak for <5 ms pulses. The VS-ST180S16M0L datasheet specifies VGT ≤3.0 V and IGT ≤150 mA at 25 °C, with derating to 40 mA at 125 °C - confirming that robust triggering requires sufficient peak energy (PGM ≤10 W) and proper dv/dt suppression on the gate line.
Is VS-ST180S16M0L lead-free and RoHS compliant?
Yes, VS-ST180S16M0L is lead (Pb)-free and RoHS compliant, as indicated by the "PbF" suffix in its full part number and confirmed in Vishay's material categorization documentation (www.vishay.com/doc?99912). The device meets EU Directive 2011/65/EU and associated amendments, with homogeneous lead content <1000 ppm. This compliance is verified per JEDEC J-STD-609 and applies to all solderable terminations and internal construction materials in the VS-ST180S16M0L.
What is the mounting torque specification for the stud terminal of VS-ST180S16M0L?
The recommended mounting torque for the 3/4"-16UNF-2A stud terminal of VS-ST180S16M0L is 24.5 N·m (210 lbf·in) when threads are lubricated, or 31 N·m (275 lbf·in) for non-lubricated threads - both with ±10 % tolerance. Proper torque ensures optimal thermal contact between the anode stud and heatsink while preventing thread damage or case deformation. This specification is explicitly stated in the Thermal and Mechanical Specifications section of the VS-ST180S16M0L datasheet (Document Number: 94397).
