Product details
Overview
TYN416RG from STMicroelectronics is a 16 A, 600 V RMS standard silicon-controlled rectifier (SCR) in TO-220AB package, with 25 mA gate trigger current, 1.6 V on-state voltage at 32 A, and 50 A/µs critical dI/dt rating. It is designed for AC line control in industrial motor starters, lighting dimmers, and solid-state relays where robust surge immunity and clip-assembly thermal performance are required.
For engineers reviewing the TYN416RG datasheet, TYN416RG pinout, TYN416RG application, or TYN416RG equivalent, key selection criteria include verified VDRM = 600 V, IT(RMS) = 16 A at Tc = 110 °C, IGT ≤ 25 mA, ITSM = 200 A (8.3 ms), and Rth(j-c) = 1.1 °C/W - all confirmed per STMicroelectronics TN1625/TYNx16 datasheet Rev 6 (Nov 2007).
Technical Context
This SCR operates as a unidirectional latching switch triggered by a positive gate pulse relative to the cathode. Its conduction initiates at gate current ≥2 mA (min) and sustains until anode current falls below 40 mA holding current (IH), with latching current (IL) ≤60 mA. The device uses planar passivated junction technology and is rated for operation up to 125 °C junction temperature.
Thermal design relies on direct case-to-heatsink mounting via the metal tab (TO-220AB), delivering 1.1 °C/W junction-to-case resistance. Surge capability is validated for non-repetitive 200 A peak (8.3 ms) and repetitive 190 A (10 ms), with fusing I²t = 180 A²s under defined conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - Maximum repetitive peak off-state voltage before unintended turn-on; defines AC mains compatibility up to 400 V RMS systems. |
| IT(RMS) | 16 A at Tc = 110 °C - Continuous RMS load current capability with heatsink; determines minimum heatsink sizing for steady-state operation. |
| IGT | ≤25 mA - Maximum gate trigger current required; sets driver strength requirement for compatible optocoupler or discrete gate circuit. |
| VTM | ≤1.6 V at ITM = 32 A - Peak on-state voltage drop; directly impacts conduction loss (P ≈ VTM × ITM) during surge events. |
| dI/dt | ≥50 A/µs - Minimum critical rate-of-rise of on-state current; ensures reliable turn-on without false triggering under fast-rising loads. |
| Rth(j-c) | 1.1 °C/W - Junction-to-case thermal resistance; enables calculation of junction temperature rise (ΔTj = P × 1.1) for thermal margin analysis. |
| IH | ≤40 mA - Maximum holding current; defines lowest sustainable anode current before commutation; critical for zero-crossing control timing. |
Pinout & Package
TYN416RG uses the TO-220AB package with isolated tab (electrically connected to cathode), standardized mechanical footprint per STMicroelectronics drawing (Ref: Table 5, dimensions A = 15.2–15.9 mm, B = 10.0–10.4 mm, ØI = 3.75–3.85 mm). Mounting torque: 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main power input terminal | Connected to AC line or high-side load; must withstand full VDRM and ITSM; requires creepage/clearance compliance in PCB layout. |
| Cathode (K) | Main power return terminal & thermal path | Electrically tied to metal tab; serves as primary heatsink interface; common reference for gate drive and load return. |
| Gate (G) | Control input terminal | Receives low-energy trigger pulse (≥2 mA, <1.3 V); polarity-sensitive (positive w.r.t. K); requires noise filtering in noisy environments. |
Key Features
| Feature | Design Value |
|---|---|
| Clip-assembly construction | Enables 200 A non-repetitive surge current (8.3 ms) without bond-wire failure - critical for motor-start transient immunity. |
| ECOPACK® lead-free packaging | Meets RoHS and JEDEC JESD97 standards; second-level interconnect marked on package; supports automated reflow and environmental compliance. |
| High dV/dt immunity | ≥500 V/µs at 125 °C with gate open - prevents false triggering in phase-angle controlled AC circuits with rapid voltage transients. |
| Low dynamic resistance | Rd ≤ 23 mΩ at 125 °C - minimizes on-state power dissipation (P = I² × Rd) during high-current conduction, improving thermal efficiency. |
| Wide junction temperature range | Tj = –40 to +125 °C - supports operation in industrial enclosures without active cooling, including ambient temperatures up to 85 °C. |
Applications
| Industrial Motor Starters | AC Lighting Dimmers |
|---|---|
Use Scenario: Controlling 3-phase induction motor startup in HVAC blowers and conveyor drives using phase-angle firing. IC Role / Device Role / Timing Role: Main power switching element in back-to-back SCR configuration; triggered synchronously with AC zero-crossing detection.

IC Role / Device Role / Timing Role: Unidirectional AC switch gated at variable delay after zero-crossing to regulate RMS power delivered to lamp filament. Use Value: 25 mA IGT ensures compatibility with low-power optocouplers (e.g., MOC3021), while 600 V VDRM supports 230 VAC mains with safety margin. |

IC Role / Device Role / Timing Role: High-reliability AC switch cycling full half-cycles to deliver precise average power to resistive heating elements. Use Value: 180 A²s I²t rating ensures survival during repeated burst-fire transitions, even with cold-resistance inrush into NiCr elements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT138-600 | VDRM = 600 V, IT(RMS) = 8 A, IGT = 15 mA, TO-220 package | Lower RMS current rating limits use to ≤5 A continuous loads; suitable only for light-duty dimmers or small SSRs. | Select when gate drive budget is tight (<15 mA) and thermal constraints prohibit larger heatsinks. |
| TYN616RG | Identical package, pinout, and ratings (16 A/600 V); same datasheet family; minor process revision | No functional difference; fully interchangeable in legacy and new designs per STMicroelectronics documentation. | Preferred for new designs requiring latest ECOPACK® compliance and documented lifecycle support. |
Compared with BT138-600, TYN416RG delivers double RMS current capacity and higher surge tolerance, making it suitable for industrial-grade loads; versus TYN616RG, it shares identical electrical and mechanical specs but reflects updated ordering nomenclature and packaging traceability.

FAQ
What is the maximum junction temperature for continuous operation?
The TYN416RG has a specified operating junction temperature range of –40 °C to +125 °C. For continuous conduction, thermal design must ensure junction temperature remains ≤125 °C under worst-case ambient and power dissipation conditions, using Rth(j-c) = 1.1 °C/W and verified heatsink performance.
Can TYN416RG be used in DC circuits?
No - TYN416RG is a standard (non-inverter-grade) SCR and cannot commutate in pure DC. It requires natural or forced current zero-crossing to reset. It is intended exclusively for AC or pulsed applications where anode current regularly falls below holding current (IH ≤ 40 mA).
Is a snubber circuit required for reliable operation?
A snubber (RC network across anode–cathode) is recommended for inductive loads or high-dI/dt environments to limit voltage overshoot during turn-off. The device's dV/dt rating (≥500 V/µs) reduces snubber dependency, but design validation per IEC 61000-4-4 is advised for industrial EMI compliance.
What is the gate trigger voltage threshold?
The maximum gate trigger voltage (VGT) is 1.3 V at Tj = 25 °C, measured with VD = 12 V and RL = 33 Ω. Gate drive circuits must supply ≥2 mA at ≤1.3 V to guarantee turn-on; typical gate resistor values range from 100 Ω to 470 Ω when driven from 5–12 V sources.
