Product details
Overview
TYN606RG from STMicroelectronics is a 6 A, 600 V RMS glass-passivated silicon controlled rectifier (SCR) designed for AC power control in resistive and inductive loads up to 400 Hz. It features 15 mA gate trigger current, 1.5 V maximum gate trigger voltage, and 2.5 °C/W junction-to-case thermal resistance, enabling use in universal motor speed controllers and industrial AC dimming circuits.
For engineers reviewing the TYN606RG datasheet, TYN606RG pinout, TYN606RG application, or TYN606RG equivalent, key selection criteria include repetitive peak off-state voltage (600 V), RMS on-state current (6 A), critical dV/dt immunity (200 V/µs at 110°C), gate sensitivity (15 mA IGT), and TO-220AB package thermal performance.
Technical Context
This SCR operates as a unidirectional latching switch triggered by a positive gate pulse relative to the cathode. Its 73 A non-repetitive surge rating (8.3 ms) and 24.5 A²s I²t fusing value support short-duration overload tolerance in mains-powered equipment.
Designed for phase-angle control topologies, it delivers stable turn-on with 2 µs typical trigger delay (tgt) under 40 mA gate drive and maintains blocking integrity with 10 µA IDRM at 25°C and 2 mA at 110°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 6 A - Sustains continuous 6 A RMS conduction at 110°C case temperature in 180° phase-controlled applications. |
| VDRM / VRRM | 600 V - Blocks up to 600 V repetitive peak off-state voltage, suitable for 230 VAC mains with safety margin. |
| IGT | 15 mA max - Low gate drive requirement enables direct interface with microcontroller GPIO or optocoupler outputs. |
| dV/dt | 200 V/µs min - High commutation immunity prevents false triggering in noisy inductive load environments. |
| Rth(j-c) | 2.5 °C/W - Enables efficient heat transfer to heatsink; supports 7 W average power dissipation at 110°C case temp. |
| tq | 70 µs typ - Fast turn-off time ensures precise phase control resolution in high-frequency dimming systems. |
Pinout & Package
TYN606RG uses the TO-220AB package: insulated tab, 3-pin vertical mounting configuration with metal tab electrically connected to the anode. The case serves as primary thermal path and electrical anode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Main power input terminal | Electrically connected to metal tab; requires insulating washer when mounted to grounded heatsink. |
| Cathode | Main power output terminal | Carries full load current to load return; low-inductance PCB layout critical for commutation stability. |
| Gate | Control input | Triggers conduction when ≥15 mA pulse applied; sensitive to dv/dt-requires RC snubber in inductive switching. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Ensures long-term reliability and moisture resistance in industrial environments without hermetic sealing. |
| ECOPACK® compliance | Lead-free second-level interconnect meets RoHS and JEDEC JESD97 marking requirements. |
| High dI/dt capability | 50 A/µs critical rate of rise supports fast turn-on into highly inductive loads like solenoids and transformers. |
| Low VTM | 1.6 V max on-state voltage at 12 A reduces conduction losses and thermal stress in high-current operation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR-based AC power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT169G | 4 A IT(RMS), 400 V VDRM, TO-92 package, higher IGT (50 mA) | Limited to lower-power, non-heatsinked applications due to thermal and voltage constraints | Select only for sub-1 A loads where board space and cost outweigh performance needs. |
| TYN612 | 6 A IT(RMS), 1200 V VDRM, same TO-220AB package, identical IGT (15 mA) | Higher blocking voltage enables use in 400 VAC industrial systems or with enhanced transient protection | Choose when system overvoltage risk exceeds 600 V or when future-proofing for higher-voltage platforms. |
Compared with BT169G and TYN612, TYN606RG offers optimal balance of 600 V blocking, 6 A current, and TO-220AB thermal performance for mainstream 230 VAC industrial controls-neither over-specified nor under-rated for typical phase-control duty.

FAQ
What is the maximum allowable case temperature for continuous operation?
The TYN606RG supports continuous operation up to 110°C case temperature (Tc), as specified in its absolute ratings. At this temperature, its RMS on-state current remains rated at 6 A with 180° conduction angle. Exceeding 110°C risks thermal runaway and permanent degradation of the gate trigger characteristics.
Can TYN606RG be used in DC circuits?
TYN606RG is not self-commutating and cannot be turned off by gate control in DC applications. It requires external circuitry-such as forced commutation via auxiliary SCRs or an LC resonant network-to interrupt current. Its design and specifications are optimized exclusively for AC line-frequency phase control (up to 400 Hz).
Is a heatsink required for 6 A RMS operation?
Yes-a heatsink is mandatory for 6 A RMS operation. With Rth(j-c) = 2.5 °C/W and typical power dissipation ~3–4 W at full load, junction temperature would exceed 125°C without thermal management. A minimum 10 cm² aluminum heatsink (with thermal interface material) is recommended to maintain Tj ≤ 125°C at 110°C ambient.
Does TYN606RG require a snubber circuit?
A snubber (RC network across anode–cathode) is strongly recommended for inductive loads to suppress dv/dt-induced false triggering and protect against voltage transients. For resistive loads at 50/60 Hz, a snubber may be omitted-but dV/dt immunity drops significantly above 110°C junction temperature, making it advisable even there.
