Product details
Overview
16TTS08FP from Vishay is a phase control silicon controlled rectifier (SCR) in TO-220AB FULL-PAK package, rated for 800 V peak reverse voltage (VRRM), 10 A average on-state current (IT(AV)), and 200 A non-repetitive surge current (ITSM). It features 1.4 V on-state voltage drop at 10 A, 500 V/µs dV/dt rating, and is designed for industrial-grade medium-power AC phase control in soft-start rectification circuits.
For engineers reviewing the 16TTS08FP datasheet, 16TTS08FP pinout, 16TTS08FP application, or 16TTS08FP equivalent, key selection criteria include verified VRRM = 800 V, IT(AV) = 10 A at Tc = 95 °C, thermal resistance RthJC = 1.5 °C/W, gate trigger current IGT ≤ 60 mA at 25 °C, and UL E78996-approved fully isolated package with 2500 VRMS insulation.
Technical Context
The 16TTS08FP operates as a unidirectional thyristor with converter-grade silicon and glass passivation, enabling reliable junction operation up to 125 °C. Its triggering behavior is defined by IGT = 60 mA (25 °C), VGT = 2.0 V (25 °C), and VGD = 0.2 V (125 °C), supporting robust gate drive design in phase-controlled rectifiers.
It delivers 1.4 V on-state voltage (VT) at 10 A and 25 °C, with on-state slope resistance rt = 24.0 mΩ at 125 °C, enabling predictable conduction loss modeling. The device supports fast switching with tgt = 0.9 µs turn-on time and trr = 4 µs reverse recovery time at 125 °C, suitable for line-frequency and low-frequency phase control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum peak reverse blocking voltage; defines safe AC line voltage derating margin for 230 VAC systems. |
| IT(AV) | 10 A - Average on-state current at Tc = 95 °C, 180° conduction; sets heatsink sizing baseline for continuous operation. |
| ITSM | 200 A - Non-repetitive surge current (10 ms sine pulse, no voltage reapplied); determines short-circuit withstand capability. |
| VT @ 10 A | 1.4 V - On-state voltage drop at 25 °C; directly impacts conduction loss (P = VT × I) and thermal design. |
| dV/dt | 500 V/µs - Minimum rate of rise of off-state voltage before false triggering; informs snubber design requirements. |
| RthJC | 1.5 °C/W - Junction-to-case thermal resistance; enables direct calculation of ΔTJ = P × 1.5 for thermal management. |
| IGT | 60 mA @ 25 °C - Maximum DC gate trigger current required; defines minimum driver output capability. |
Pinout & Package
TO-220AB FULL-PAK package with fully isolated case (VINS = 2500 VRMS, UL E78996 certified), 3-terminal configuration, and mounting torque 6–12 kgf·cm (5–10 lbf·in).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current return path; electrically connected to isolated metal tab; must be insulated from heatsink unless referenced to system ground. |
| 2 (A) | Anode | Main power input terminal; carries full load current during conduction; polarity-sensitive for forward biasing. |
| 3 (G) | Gate | Control input for turn-on; requires ≥2.0 V and ≥60 mA (25 °C) to reliably trigger; sensitive to noise and dV/dt. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable operation up to TJ = 125 °C without degradation; eliminates need for hermetic sealing in industrial environments. |
| Fully isolated package (2500 VRMS) | Eliminates requirement for insulating washers or pads when mounted to grounded heatsinks; simplifies mechanical assembly. |
| Converter-grade silicon | Optimized for phase control waveforms with high di/dt (150 A/µs) and dv/dt (500 V/µs); ensures reliable commutation in bridge topologies. |
| Low on-state slope resistance (24 mΩ) | Reduces conduction loss variation across temperature; improves thermal stability in high-current, high-temperature applications. |
| UL E78996 certification | Validates safety compliance for industrial equipment; satisfies regulatory requirements for isolation and creepage/clearance. |
Applications
| Motor Soft-Start Control | Industrial Heating Control |
|---|---|
|

IC Role / Device Role / Timing Role: Main power switch in AC line-connected SCR-based power controller, operating at 50/60 Hz line frequency. Use Value: Supports continuous 10 A average current at 125 °C junction temperature; glass passivation ensures long-term reliability under thermal cycling. |
| Capacitive Input Filter Rectification | Welding Power Supply Control |
|
Use Scenario: Input stage of switched-mode power supplies where high peak currents occur due to capacitive input filtering. IC Role / Device Role / Timing Role: Line-synchronized SCR in half-wave or full-wave rectifier configuration, conducting only during selected portions of AC cycle. Use Value: Withstands 200 A non-repetitive surge (ITSM) and exhibits low VT (1.4 V) to minimize losses during high-peak-current conduction periods. |
Use Scenario: Primary-side AC power control in resistance spot welding equipment requiring precise energy delivery per weld cycle. IC Role / Device Role / Timing Role: High-current phase-controlled switch in transformer primary circuit, triggered synchronously with line zero-crossing. Use Value: Rated for 150 A/µs dI/dt and 500 V/µs dV/dt; RthJC = 1.5 °C/W enables rapid heat transfer to heatsink during intermittent high-duty-cycle operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar phase control SCR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST162S08 | VRRM = 800 V, IT(AV) = 16 A, TO-220AC package (non-isolated case), RthJC = 1.0 °C/W | Requires insulating hardware for heatsink mounting; higher IT(AV) allows lower thermal margin but lacks 2500 VRMS isolation. | Select when higher average current headroom is needed and isolation can be managed externally. |
| IXYS MCR16-8 | VRRM = 800 V, IT(AV) = 16 A, TO-220AB package (isolated), IGT = 50 mA max (25 °C), RthJC = 1.4 °C/W | Lower gate trigger sensitivity reduces driver complexity; identical isolation rating but tighter thermal resistance spec. | Prefer when minimizing gate drive power or optimizing thermal performance is critical. |
Compared with ST162S08 and IXYS MCR16-8, the 16TTS08FP offers UL-certified 2500 VRMS isolation in a standard footprint while maintaining industry-standard IGT and dV/dt ratings-making it optimal for safety-critical industrial controls where mounting simplicity and regulatory compliance are prioritized over marginal current or thermal improvements.

FAQ
What is the maximum junction temperature rating for the 16TTS08FP?
The 16TTS08FP has a maximum junction temperature (TJ) rating of 125 °C, validated under continuous operation with proper heatsinking. This rating is enabled by glass passivation technology and is specified across all electrical parameters in the datasheet-including VT, IGT, and dV/dt-ensuring consistent performance up to this limit. Derating curves in Figure 1 confirm usable IT(AV) at elevated case temperatures.
Does the 16TTS08FP require an insulating pad when mounted to a heatsink?
No-the 16TTS08FP uses a fully isolated TO-220AB FULL-PAK package with 2500 VRMS insulation (UL E78996 certified), so its metal tab is electrically isolated from all terminals. It can be mounted directly to a grounded heatsink without insulating hardware, reducing thermal resistance and assembly complexity compared to non-isolated SCRs like TO-220AC variants.
What is the gate trigger current specification for the 16TTS08FP at elevated temperature?
The 16TTS08FP requires a maximum DC gate trigger current (IGT) of 35 mA at TJ = 125 °C, per the Absolute Maximum Ratings table. This value is lower than the 60 mA specified at 25 °C, reflecting reduced gate sensitivity at high temperature-a critical parameter for designing fail-safe gate drivers that maintain reliable turn-on across the full operating range.
Can the 16TTS08FP be used in three-phase bridge configurations?
Yes-the 16TTS08FP is explicitly rated for three-phase bridge operation, with output current capability of 17 A at TA = 55 °C and TJ = 125 °C using a common 1 °C/W heatsink. Its 150 A/µs dI/dt rating and 500 V/µs dV/dt rating ensure robust commutation in multi-thyristor bridge topologies commonly deployed in industrial motor drives and power converters.
How does the 16TTS08FP differ from the 16TTS12FP variant?
The 16TTS08FP and 16TTS12FP share identical package, thermal specs, and gate characteristics-but differ exclusively in voltage rating: 16TTS08FP is rated for 800 V VRRM/VDRM, while 16TTS12FP is rated for 1200 V. Both exhibit the same 10 A IT(AV), 200 A ITSM, and 1.4 V VT, making them functionally interchangeable in designs where voltage margin permits, but not pin-compatible replacements due to distinct voltage-class qualification.
