Product details
Overview
TYN1008RG from STMicroelectronics is a standard-sensitivity 8 A, 600 V silicon-controlled rectifier (SCR) in TO-220AB package, rated for 8 A RMS on-state current at TC = 110 °C and 15 mA maximum gate trigger current, designed for overvoltage crowbar protection and motor control circuits in power tools and kitchen appliances.
For engineers reviewing the TYN1008RG datasheet, TYN1008RG pinout, TYN1008RG application, or TYN1008RG equivalent, this device serves as a robust, thermally efficient thyristor for phase-controlled AC switching, surge protection, and inrush limiting where precise gate sensitivity and high dV/dt immunity are required.
Technical Context
This SCR operates with a standard gate trigger current range of 2–15 mA (max), exhibits 150 V/µs minimum dV/dt immunity at Tj = 125 °C with gate open, and maintains 30 mA maximum holding current - enabling reliable turn-on under noisy line conditions and stable latching in high-temperature industrial environments.
Its on-state voltage is capped at 1.6 V at 16 A pulse, with dynamic resistance ≤46 mΩ and threshold voltage ≤0.85 V at 125 °C, supporting low conduction losses in continuous-duty applications such as AC motor speed control and regulated power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A - Sustains continuous AC load current up to 8 A at case temperature 110 °C |
| VDRM / VRRM | 600 V - Blocks 600 V peak reverse/forward voltage before conduction |
| IGT (max) | 15 mA - Maximum gate current needed to reliably trigger at 25 °C |
| dV/dt (min) | 150 V/µs - Immune to rapid voltage transients without false triggering |
| VTM (max) | 1.6 V - On-state voltage drop at 16 A pulse, defining conduction loss |
| IH (max) | 30 mA - Minimum anode current required to maintain conduction after triggering |
| Rth(j-c) | 1.3 °C/W - Junction-to-case thermal resistance enables effective heatsinking |
Pinout & Package
TYN1008RG uses the TO-220AB package: insulated tab, through-hole mounting, 3-pin configuration with integral metal tab for thermal and electrical connection to cathode. Mounting torque: 0.55 N·m (recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Carries full load current into device; must withstand peak line voltage and surge currents |
| Cathode (K) | Main current exit terminal & thermal path | Connected to heatsink via insulated tab; defines reference potential for gate drive |
| Gate (G) | Control input for turn-on | Receives low-energy pulse (≤15 mA) to initiate conduction; referenced to cathode |
Key Features
| Feature | Design Value |
|---|---|
| Standard gate sensitivity | IGT = 2–15 mA - Balances noise immunity and drive simplicity in industrial controls |
| High dV/dt immunity | 150 V/µs - Prevents spurious turn-on during fast-switching transients in motor drives |
| Low on-state loss | VTM ≤ 1.6 V @ 16 A - Reduces power dissipation and thermal stress in 8 A RMS operation |
| Robust surge rating | ITSM = 95 A @ 10 ms - Withstands repetitive inrush events in appliance power-up cycles |
| Thermal performance | Rth(j-c) = 1.3 °C/W - Enables compact heatsink design for TO-220AB mounting |
Applications
| Overvoltage Crowbar Protection | AC Motor Speed Control |
|---|---|
|
Use Scenario: Fast-acting short-circuit clamp triggered by overvoltage detection circuit to protect downstream DC bus or sensitive loads. IC Role / Device Role / Timing Role: Thyristor acting as crowbar switch; latches on within microseconds upon gate pulse and remains conducting until power cycle reset. Use Value: Limits transient overvoltage to <10 V above rail using low-VTM conduction, preventing damage to IGBTs or microcontrollers. |
Use Scenario: Phase-angle controlled AC power delivery to universal motors in corded power tools and blenders. IC Role / Device Role / Timing Role: Main power switch in single-phase AC line; gated at precise points in sine wave to regulate average power. Use Value: Delivers smooth torque control with minimal EMI due to deterministic zero-crossing commutation and 150 V/µs dV/dt margin. |
| Inrush Current Limiting | Voltage Regulation Circuits |
|
Use Scenario: Controlled turn-on of large capacitive input stages in SMPS or battery chargers to avoid fuse blowing or rectifier stress. IC Role / Device Role / Timing Role: Series-connected SCR that delays full conduction until bulk capacitor voltage rises, then latches on. Use Value: Limits peak inrush to <20 A for >100 ms using 8 A RMS rating and 95 A surge capability, extending component life. |
Use Scenario: Feedback-controlled AC voltage regulation in laboratory bench supplies or HVAC fan controllers. IC Role / Device Role / Timing Role: Line-synchronized switching element modulating RMS output voltage via firing angle adjustment. Use Value: Achieves ±1% output stability across 0–100% load with 30 mA IH ensuring no dropout during light-load zero-crossing intervals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TYN608RG | Identical package, same 600 V/8 A rating, but marked as TYN608RG per ordering code - confirmed as direct variant of TYN1008RG per ST DS2118 Rev 9 Table 10 | No functional difference; identical use in crowbar, motor control, and regulation | Select when cross-referencing legacy ST documentation or distributor stock labeled TYN608RG |
| BT151-650R | 650 V VDRM, 12 A IT(RMS), TO-220AB, IGT max = 15 mA - higher voltage margin and current headroom | Better suited for 230 VAC systems with high line surges or designs requiring extended lifetime margin | Choose when system peak voltage exceeds 600 V or long-term reliability demands >2× RMS derating |
Compared with TYN1008RG, TYN608RG offers identical electrical and thermal specs in the same TO-220AB package, while BT151-650R provides higher voltage and current ratings at the cost of slightly larger footprint and different gate drive optimization - making it suitable for upgraded designs rather than drop-in replacement.

FAQ
What is the maximum junction temperature for continuous operation?
The TYN1008RG has an operating junction temperature range of –40 °C to +125 °C. For continuous RMS current operation, thermal design must ensure junction temperature stays within this limit - typically achieved using a heatsink sized to maintain case temperature ≤110 °C per the 8 A IT(RMS) rating.
Can TYN1008RG be used in surface-mount designs?
No - TYN1008RG is packaged exclusively in TO-220AB, a through-hole power package with insulated metal tab. It requires mechanical mounting and screw-type heatsinking. For surface-mount alternatives, consider ST's DPAK-packaged TN805-600B or TS820-600B variants.
Is a snubber circuit required for reliable operation?
A snubber is recommended when driving inductive loads or operating near the 150 V/µs dV/dt limit. The device's inherent dV/dt immunity reduces snubber dependency, but a simple RC network (e.g., 100 Ω + 100 nF) improves robustness in motor control or transformer-coupled applications.
What is the gate-cathode voltage limit during reverse bias?
The maximum peak reverse gate voltage (VRGM) for TYN1008RG is 5 V, as specified in Table 1. Exceeding this risks gate junction damage. Gate drive circuits must include clamping (e.g., bidirectional TVS or Zener diode) to prevent negative excursions beyond –5 V relative to cathode.
