Product details
Overview
TYN608RG from STMicroelectronics is a standard-sensitivity 8 A, 600 V silicon-controlled rectifier (SCR) in TO-220AB package, designed for line-commutated AC power control. It delivers 8 A RMS on-state current at 110 °C case temperature, supports 15 mA gate trigger current, and features 150 V/µs dV/dt immunity at 125 °C - enabling robust operation in motor control and overvoltage crowbar circuits.
For engineers reviewing the TYN608RG datasheet, TYN608RG pinout, TYN608RG application, or TYN608RG equivalent, key selection criteria include verified 600 V repetitive peak off-state voltage, confirmed 15 mA maximum gate trigger current, validated TO-220AB thermal resistance of 1.3 °C/W (junction-to-case), and documented 30 mA holding current at 125 °C.
Technical Context
This SCR operates in natural commutation mode with gate-controlled turn-on only; it lacks gate turn-off capability. Its 150 V/µs dV/dt immunity at 125 °C and 30 mA holding current ensure reliable latching under high-noise industrial AC line conditions.
The device uses planar passivated junction technology with glass-passivated chip bonding, supporting stable operation across –40 to +125 °C junction temperature range and delivering 1.6 V max on-state voltage at 16 A pulse current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - blocks 600 V peak reverse or off-state voltage without conduction |
| IT(RMS) | 8 A - sustains 8 A RMS load current at TC = 110 °C with heatsink |
| IGT (max) | 15 mA - maximum gate current required to reliably trigger at 25 °C |
| dV/dt (min) | 150 V/µs - minimum rate of voltage rise the device withstands before false triggering |
| VTM (max) | 1.6 V - maximum on-state voltage drop at 16 A pulse, defining conduction loss |
| IH (max) | 30 mA - maximum holding current needed to maintain conduction after triggering |
| Rth(j-c) | 1.3 °C/W - thermal resistance from junction to case, critical for heatsink sizing |
Pinout & Package
TYN608RG uses the TO-220AB package: insulated tab, 3-pin through-hole mounting, 2.3 g mass, and 0.55 N·m recommended mounting torque. The plastic body meets UL94 V0 and is halogen-free per ECOPACK standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry during conduction | Connected to positive AC line or DC supply; carries full load current |
| Cathode (K) | Main current exit during conduction | Connected to load return path; forms low-impedance conduction loop with anode |
| Gate (G) | Trigger control input | Receives 15 mA pulse to initiate conduction; referenced to cathode |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TYN612RG | 12 A IT(RMS), same 600 V VDRM, 15 mA IGT, TO-220AB | Higher current handling for larger motors or higher-power crowbars | Select when >8 A continuous load current or higher surge margin is required |
| BT169G | 4 A IT(RMS), 400 V VDRM, 5 mA IGT, TO-92 | Lower power, lower voltage, smaller package - not drop-in compatible | Use only in low-power signal-level triggering or auxiliary control stages |
Compared with TYN608RG, TYN612RG offers higher current headroom but identical gate drive and thermal interface; BT169G provides lower-cost, lower-power switching but cannot replace TYN608RG in 8 A main power paths due to current and voltage limitations.

FAQ
What is the maximum junction temperature for continuous operation?
The TYN608RG has a specified operating junction temperature range of –40 to +125 °C. Continuous operation must maintain Tj ≤ +125 °C, which requires proper heatsinking based on its 1.3 °C/W junction-to-case thermal resistance and ambient conditions.
Can TYN608RG be used in DC circuits?
TYN608RG can conduct DC current once triggered, but it cannot be turned off by gate control - it requires external current interruption (e.g., series switch or load removal). It is primarily intended for AC line-commutated applications like phase control and crowbar protection.
Is a snubber circuit required for reliable operation?
A snubber (RC network across anode–cathode) is recommended when driving inductive loads or in high-dV/dt environments, even though TYN608RG specifies 150 V/µs immunity. This mitigates voltage overshoot during turn-off and prevents false triggering in marginal designs.
What is the gate-cathode voltage limit during reverse bias?
The TYN608RG has a maximum peak reverse gate voltage (VRGM) of 5 V. Exceeding this risks gate junction damage; therefore, reverse-biased gate drive circuits must clamp or limit gate–cathode voltage to ≤5 V using Zener diodes or active clamping.
