Product details
Overview
TS820-600T from STMicroelectronics is a sensitive-gate 8 A, 600 V silicon-controlled rectifier (SCR) in TO-220AB package, designed for precise triggering in crowbar protection, motor control, and capacitive discharge ignition circuits. It delivers 200 µA max gate trigger current (IGT), 1.6 V max on-state voltage (VTM) at 16 A, and 50 A/µs critical rate of rise of on-state current (dl/dt) at 125 °C.
For engineers reviewing the TS820-600T datasheet, TS820-600T pinout, TS820-600T application, or TS820-600T equivalent, this page provides verified electrical specs, thermal resistance data (Rth(j-c) = 1.3 °C/W), gate sensitivity curves, and real-world use cases in overvoltage protection and phase-controlled power tools.
Technical Context
This SCR uses a planar passivated junction structure optimized for high dV/dt immunity (≥5 V/µs at 125 °C with RGK = 220 Ω) and low IGT stability across temperature. Its sensitive gate enables reliable turn-on with microamp-level drive, eliminating need for external amplification in low-power control stages.
Thermal design is supported by DC junction-to-case resistance of 1.3 °C/W in TO-220AB, enabling 8 A RMS conduction at TC = 110 °C. The device maintains stable holding current (IH ≤ 5 mA) and latching current (IL ≤ 6 mA) over -40 to +125 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A - Sustains continuous 8 A RMS load current at TC = 110 °C without thermal runaway |
| VDRM / VRRM | 600 V - Blocks up to 600 V peak reverse or off-state voltage in AC line applications |
| IGT (max) | 200 µA - Enables direct drive from low-power logic or microcontroller GPIO without buffer stage |
| VTM (max) | 1.6 V @ 16 A - Limits conduction loss to <2.6 W at full surge, reducing heatsink requirements |
| dl/dt (min) | 50 A/µs - Resists false triggering during fast current transients in motor commutation |
| dV/dt (min) | 5 V/µs @ Tj = 125 °C - Maintains blocking integrity under high dv/dt noise in industrial environments |
| Rth(j-c) | 1.3 °C/W - Allows direct mounting to heatsink for efficient thermal transfer in compact enclosures |
Pinout & Package
TS820-600T uses the TO-220AB package: insulated tab, 3-pin through-hole, lead-free plating, recommended torque 0.55 N·m. Thermal path optimized via metal tab contact to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Carries full load current into device; must be connected to positive rail or AC phase |
| Cathode (K) | Main current exit terminal | Completes main conduction path; referenced as circuit ground or neutral return |
| Gate (G) | Trigger control input | Accepts low-energy pulse (≥200 µA) to initiate conduction; requires no sustained drive |
Key Features
| Feature | Design Value |

| Sensitive gate triggering | 200 µA max IGT enables direct MCU GPIO control without external driver circuitry |
| High dV/dt immunity | 5 V/µs minimum at 125 °C ensures robust operation in noisy motor-drive or SMPS environments |
| Low on-state voltage | 1.6 V max VTM reduces conduction losses and simplifies thermal management at 8 A RMS |
| Stable holding current | 5 mA max IH over -40 to +125 °C guarantees reliable turn-off after gate signal removal |
| Optimized thermal resistance | 1.3 °C/W Rth(j-c) supports high-power density designs with minimal heatsink footprint |
Applications
| Overvoltage Crowbar Protection | Power Tool Motor Control |
|---|---|
|
Use Scenario: Fast-acting short-circuit clamp triggered by voltage supervisor IC when supply exceeds safe threshold. IC Role / Device Role / Timing Role: SCR acts as crowbar switch; conducts within microseconds upon gate pulse to collapse rail and protect downstream ICs. Use Value: 200 µA IGT allows direct drive from comparator output; 600 V VDRM covers 400 VAC-derived rails with margin. |
Use Scenario: Phase-angle controlled AC motor speed regulation in corded drills and sanders. IC Role / Device Role / Timing Role: SCR serves as main power switch; gated once per half-cycle to adjust average power delivered to universal motor. Use Value: 8 A IT(RMS) handles peak motor currents; 50 A/µs dl/dt prevents false turn-on during brush-commutation spikes. |
| Inrush Current Limiting | Capacitive Discharge Ignition (CDI) |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS820-600H | Same electrical specs, but IPAK package (Rth(j-c) = 1.3 °C/W, larger footprint, surface-mount) | Preferred for automated assembly; requires PCB copper area for thermal relief instead of mechanical heatsink | Select when board space permits SMT layout and reflow compatibility is required |
| TN805-600B | Standard-gate SCR (IGT = 5 mA max), DPAK package, higher IGT demands driver stage | Better suited for high-noise environments where higher gate immunity reduces false triggering risk | Choose when gate drive capability exceeds 5 mA and cost-sensitive DPAK form factor is acceptable |
Compared with TS820-600H, TS820-600T offers identical electrical performance but enables through-hole mechanical mounting and direct heatsinking; versus TN805-600B, it trades higher gate sensitivity for lower noise immunity-critical when driving from weak signal sources.

FAQ
What is the maximum junction temperature for continuous operation?
The TS820-600T has an operating junction temperature range of -40 to +125 °C. Continuous conduction at rated IT(RMS) = 8 A requires case temperature not exceeding 110 °C, enforced via heatsink design using its 1.3 °C/W Rth(j-c) value. Exceeding 125 °C risks irreversible parametric shift or latch-up failure.
Can TS820-600T replace a standard-gate SCR like TN805-600B without circuit modification?
No-TS820-600T has 200 µA max IGT versus 5 mA for TN805-600B. Substituting it into a circuit designed for standard gate drive may cause unreliable turn-on due to insufficient gate current. Gate resistor values and driver strength must be re-evaluated to ensure ≥200 µA is delivered under worst-case conditions.
Is the TO-220AB package electrically insulated?
No-the TO-220AB package used in TS820-600T has an electrically conductive metal tab connected to the Anode (A). Electrical isolation from heatsink or chassis requires mica or polymer insulator washer and shoulder washer on the mounting screw, plus appropriate creepage/clearance allowances per safety standards.
What is the minimum gate-cathode resistance needed to ensure reliable turn-off?
Based on Figure 8 in DS2118, holding current (IH) rises with increasing RGK; at RGK = 1 kΩ, IH remains ≤5 mA up to 125 °C. To guarantee turn-off, external gate-cathode resistance should not exceed 1 kΩ. Higher values risk failure to commutate due to elevated IH, especially at elevated junction temperatures.
