Product details
Overview
VS-16TTS16S-M3 from Vishay Semiconductors is a surface-mount silicon-controlled rectifier (SCR) designed for medium-power phase control and switching applications, featuring 1600 V peak reverse/direct voltage rating, 10 A average on-state current, 1.4 V on-state voltage drop at 10 A and 25 °C, 60 mA gate trigger current at 25 °C, and D2PAK (TO-263AB) package with glass passivation enabling reliable operation up to 125 °C junction temperature in soft-start input rectification circuits.
For engineers reviewing the VS-16TTS16S-M3 datasheet, VS-16TTS16S-M3 pinout, VS-16TTS16S-M3 application, or VS-16TTS16S-M3 equivalent, key selection criteria include its 1600 V blocking capability, thermal resistance of 1.3 °C/W (junction-to-case), gate trigger sensitivity across temperature (-10 °C to 125 °C), dV/dt immunity of 500 V/μs, and compatibility with standard FR-4 PCB footprints per AN-994.
Technical Context
This SCR operates as a single-phase, unidirectional, gate-triggered thyristor with latching behavior after turn-on, requiring gate pulse energy within PGM = 8 W (5 ms) and PG(AV) = 2.0 W limits. Its triggering is specified under resistive load conditions at 6 V anode supply, with IGT ranging from 35 mA (125 °C) to 90 mA (-10 °C) and VGT from 1.0 V to 3.0 V.
Thermal design relies on direct case-to-heatsink conduction via the D2PAK thermal pad (RthJC = 1.3 °C/W DC), supporting 14.0 A in aluminum IMS with heatsink (RthCA = 5 °C/W). It exhibits 0.9 μs typical turn-on time and 110 μs typical turn-off time at 25 °C, with 200 A non-repetitive surge current capability under zero-voltage reapplied conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 10 A average on-state current at TC = 93 °C, 180° conduction - defines continuous power handling in phase-controlled AC loads |
| VRRM / VDRM | 1600 V peak reverse/direct blocking voltage - enables use in 1100 V RMS line applications with safety margin |
| VTM | 1.4 V on-state voltage at 10 A and 25 °C - determines conduction loss and thermal dissipation in steady-state operation |
| IGT | 60 mA max gate trigger current at 25 °C - sets minimum driver strength required for reliable turn-on |
| dV/dt | 500 V/μs critical rate-of-rise immunity - prevents false triggering from line transients without snubber |
| RthJC | 1.3 °C/W junction-to-case thermal resistance - mandates direct thermal interface to heatsink for high-current operation |
| tq | 110 μs typical turn-off time at 25 °C - constrains maximum operating frequency in forced-commutated circuits |
Pinout & Package
D2PAK (TO-263AB) surface-mount package with isolated thermal pad (pin 3), 3-terminal configuration, and JEDEC-compliant outline per document 96164. Footprint requires 650 mm² FR-4 copper area for 40 °C/W RthJA rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main current entry terminal; electrically connected to thermal pad - must be routed for high-current and thermal conduction |
| 2 | Gate | Control input; low-energy pulse triggers latching conduction - requires <3.0 V VGT and <90 mA IGT over full temperature range |
| 3 | Cathode | Main current exit terminal; tied to PCB ground plane in most phase-control topologies - carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage blocking | 1600 V VRRM/VDRM supports 400–690 VAC industrial systems with margin against transients |
| Glass passivation | Enables stable 125 °C junction operation without degradation - eliminates need for derating below Tj max |
| MSL Level 1 | Compatible with standard SMT reflow profiles up to 245 °C peak - no moisture sensitivity handling required |
| Low thermal resistance | RthJC = 1.3 °C/W allows >14 A output with heatsink - reduces heatsink size vs. TO-220 alternatives |
| Halogen-free & RoHS | -M3 suffix confirms lead-free terminations, halogen-free molding compound, and full RoHS compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR phase control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST16S16F | Same 1600 V VRRM, 10 A IT(AV), but TO-220FP package - higher RthJA (60 °C/W), no thermal pad | Limited to lower-power or heatsink-mounted designs; unsuitable for high-density SMT layouts | Select when through-hole assembly or legacy footprint compatibility is required |
| IXYS MCR16S16 | 1600 V VRRM, 16 A IT(RMS), but 12 A IT(AV); TO-220AB package; higher IGT (100 mA) | Better surge rating (250 A ITSM), but larger footprint and less gate sensitivity - needs stronger driver | Select when higher RMS current or ruggedness outweighs SMT advantage and gate drive simplicity |
Compared with ST16S16F and IXYS MCR16S16, the VS-16TTS16S-M3 offers superior thermal performance in SMT form factor (RthJC = 1.3 °C/W), tighter gate trigger specs (60 mA IGT), and MSL Level 1 reflow compatibility - making it optimal for space-constrained, high-reliability industrial controls where board-level thermal management is prioritized.

FAQ
What is the maximum junction temperature specification for VS-16TTS16S-M3?
The VS-16TTS16S-M3 has a maximum junction temperature (TJ) rating of +125 °C, verified per JEDEC JESD47 qualification. This rating is enabled by glass passivation technology and applies across the full operating range. Derating curves in the datasheet (Document 96413, Fig. 1–2) define allowable average current versus case temperature, with full 10 A IT(AV) permitted only when TC ≤ 93 °C. The VS-16TTS16S-M3 must be mounted per recommended footprint (650 mm² FR-4 copper) to sustain this rating.
Does VS-16TTS16S-M3 support lead-free reflow soldering?
Yes, the VS-16TTS16S-M3 is rated MSL Level 1 per J-STD-020 and qualified for lead-free reflow with a maximum peak temperature of 245 °C. The -M3 suffix explicitly denotes halogen-free, RoHS-compliant construction with lead-free terminations. No moisture baking is required prior to assembly. Thermal profile compliance assumes standard D2PAK footprint per Vishay application note AN-994 and JEDEC TO-263AB land pattern dimensions (Doc. 96164).
What is the gate trigger voltage requirement for VS-16TTS16S-M3 at elevated temperature?
The VS-16TTS16S-M3 requires a maximum DC gate trigger voltage (VGT) of 1.0 V at TJ = 125 °C, measured with 6 V anode supply and resistive load. This low threshold ensures reliable triggering even under worst-case thermal conditions. Gate drive circuits must deliver ≥1.0 V but ≤0.25 V VGD (non-trigger voltage) at 125 °C to avoid false turn-on. The VS-16TTS16S-M3 gate characteristics (Fig. 9) confirm stable operation across -10 °C to 125 °C with defined load-line constraints.
Can VS-16TTS16S-M3 be used in three-phase bridge configurations?
Yes, the VS-16TTS16S-M3 is explicitly rated for three-phase bridge applications, delivering up to 9.5 A average output current when mounted on aluminum IMS with RthCA = 15 °C/W (per datasheet Table "OUTPUT CURRENT IN TYPICAL APPLICATIONS"). Each VS-16TTS16S-M3 serves as one leg in a six-pulse configuration. Its 500 V/μs dV/dt rating and 110 μs tq support commutation in standard 50/60 Hz systems. Layout must ensure symmetrical gate drive and thermal coupling across all six devices.
What is the thermal resistance from junction to case (RthJC) for VS-16TTS16S-M3?
The VS-16TTS16S-M3 has a maximum junction-to-case thermal resistance (RthJC) of 1.3 °C/W under DC operation, as specified in the Absolute Maximum Ratings table (Document 96413, page 2). This value is measured from the silicon die to the exposed thermal pad (pin 3) and is critical for heatsink sizing. Achieving this value requires full-surface soldering of the thermal pad to a copper pour with ≥650 mm² area and ≥4 oz. copper thickness, per AN-994 guidelines. The VS-16TTS16S-M3 thermal performance degrades significantly if the thermal pad is undersized or poorly soldered.
