Product details
Overview
TS820-600FP from STMicroelectronics is a sensitive-gate 8 A, 600 V silicon-controlled rectifier (SCR) in TO-220FPAB package, rated for 8 A RMS on-state current at TC = 91 °C and 0.2 mA max gate trigger current (IGT), designed for overvoltage crowbar protection and motor control circuits in power tools and kitchen appliances.
For engineers reviewing the TS820-600FP datasheet, TS820-600FP pinout, TS820-600FP application, or TS820-600FP equivalent, this device offers verified low IGT (200 µA typ.), high dV/dt immunity (5 V/µs min. at Tj = 125 °C), and thermal resistance Rth(j-c) = 4.6 °C/W - critical for compact crowbar and phase-control designs requiring stable turn-on under low-current gate drive.
Technical Context
This SCR operates as a latching unidirectional switch with sensitive gate triggering (IGT ≤ 200 µA), enabling direct drive from microcontrollers or optocouplers without external amplification. Its 600 V repetitive peak off-state voltage (VDRM/VRRM) supports universal AC line operation up to 265 VAC.
It features a threshold voltage (Vt0) ≤ 0.85 V and dynamic resistance (Rd) ≤ 46 mΩ at Tj = 125 °C, ensuring low conduction loss during 16 A surge pulses. Holding current (IH) remains ≤ 5 mA across -40 to +125 °C junction temperature range, supporting reliable latch retention in variable-temperature environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A RMS on-state current at TC = 91 °C - supports continuous 8 A load switching in heatsink-limited TO-220FPAB layouts |
| VDRM / VRRM | 600 V repetitive peak off-state voltage - enables use in 230 VAC mains applications with ≥2× safety margin |
| IGT (max) | 200 µA at VD = 12 V, RL = 140 Ω - allows direct MCU GPIO or low-power optocoupler drive without buffer stage |
| dV/dt (min) | 5 V/µs at Tj = 125 °C, RGK = 220 Ω - ensures noise-immune commutation in noisy motor-drive or SMPS environments |
| VTM (max) | 1.6 V at ITM = 16 A, tp = 380 µs - limits conduction loss to <2.56 W peak during surge events |
| Rth(j-c) | 4.6 °C/W - defines minimum heatsink requirement: ~10 °C/W total thermal resistance needed for 8 A continuous operation |
| ITSM (tp=10 ms) | 70 A non-repetitive surge current - withstands inrush surges in capacitive discharge ignition or soft-start circuits |
Pinout & Package
TO-220FPAB is a through-hole, insulated-tab package with 3 leads: Anode (A), Cathode (K), and Gate (G). The plastic body provides electrical isolation between tab (Anode-connected) and mounting surface, eliminating need for insulating washers in heatsinked applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Connected to high-side AC line or DC bus; tab is electrically tied to Anode - requires isolation from heatsink unless system ground referenced |
| Cathode (K) | Main current exit terminal | Reference node for gate drive; connects to load return path; defines common reference for triggering circuitry |
| Gate (G) | Control input for turn-on | Sensitive input requiring ≤200 µA to initiate conduction; polarity-sensitive (positive w.r.t. cathode); must be current-limited to avoid damage |
Key Features
| Feature | Design Value |
|---|---|
| Sensitive gate triggering | IGT ≤ 200 µA enables direct drive from 3.3 V/5 V MCUs or low-current optocouplers (e.g., PC817, VO615A) |
| High dV/dt immunity | 5 V/µs minimum at 125 °C ensures robust operation in EMI-prone motor control and crowbar circuits |
| Low conduction loss | Vt0 ≤ 0.85 V and Rd ≤ 46 mΩ reduce power dissipation during sustained 8 A conduction |
| Thermal performance | Rth(j-c) = 4.6 °C/W allows >6 W continuous power dissipation with modest heatsinking (e.g., 15 °C/W sink) |
| Insulated package | TO-220FPAB's isolated tab eliminates need for mica washers or silicone pads - simplifies mechanical assembly and improves thermal reliability |
Applications
| Overvoltage Crowbar Protection | Power Tool Motor Control |
|---|---|
|
Use Scenario: Fast-acting short-circuit clamp triggered by overvoltage detection IC (e.g., TL431 + optocoupler) to protect downstream DC bus from transient spikes. IC Role / Device Role / Timing Role: Latching high-current shunt switch activated within microseconds of fault detection; holds until main supply is cycled. Use Value: 200 µA IGT allows direct interface with low-power fault comparators; 70 A ITSM handles energy dump from bulk capacitors without failure. |
Use Scenario: Phase-angle controlled AC motor speed regulation in corded drills and saws using zero-crossing synchronized gate pulses. IC Role / Device Role / Timing Role: Main power switch modulating RMS voltage delivered to universal motor; gated at precise firing angle per half-cycle. Use Value: 5 V/µs dV/dt immunity prevents false triggering from commutation noise; 8 A IT(RMS) sustains peak torque loads during stall conditions. |
| Inrush Current Limiting | Capacitive Discharge Ignition (CDI) |
|
Use Scenario: Soft-start circuit limiting surge into large input capacitors of industrial power supplies or battery chargers. IC Role / Device Role / Timing Role: Delayed-turn-on switch bypassing NTC thermistor after warm-up; triggered once steady-state is confirmed. Use Value: Low IGT enables timing control via RC network + comparator; 46 mΩ Rd minimizes steady-state voltage drop during bypass mode. |
Use Scenario: High-voltage pulse generator in small-engine ignition systems, discharging capacitor bank into ignition coil primary. IC Role / Device Role / Timing Role: Precision-triggered discharge switch synchronizing spark timing with engine crank position. Use Value: 70 A ITSM safely handles 50–100 A pulse currents; 1.6 V VTM ensures minimal energy loss during rapid discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS820-600T | Same die, TO-220AB package (non-insulated tab); Rth(j-c) = 1.3 °C/W vs. 4.6 °C/W | Requires insulating hardware when mounted to grounded heatsink; better for high-power, mechanically secured assemblies | Select when thermal performance is prioritized over mounting simplicity and isolation is managed externally |
| TS820-600H | Same die, IPAK package; Rth(j-c) = 1.3 °C/W; surface-mount compatible; higher thermal mass | Designed for automated SMT assembly; unsuitable for manual through-hole prototyping or field repair | Select for volume production where reflow compatibility and board space savings outweigh through-hole serviceability |
Compared with TS820-600FP, the TO-220AB variant delivers superior thermal conductivity but adds mechanical complexity, while the IPAK version enables automation at the cost of manual handling feasibility - the FPAB variant uniquely balances isolation, thermal adequacy, and serviceability for mid-volume industrial controls.

FAQ
What is the maximum junction temperature for continuous operation?
The TS820-600FP has an operating junction temperature range of -40 to +125 °C. For continuous 8 A RMS conduction, case temperature must not exceed 91 °C per datasheet derating curves - requiring thermal design that maintains TC ≤ 91 °C under worst-case ambient and airflow conditions.
Can TS820-600FP be driven directly from a 3.3 V microcontroller GPIO?
Yes - with appropriate current-limiting. At 3.3 V, a 10 kΩ series resistor delivers ~330 µA, exceeding the 200 µA max IGT. However, ensure gate pulse width ≥ 20 µs and use a flyback diode or RC snubber if driving inductive loads to prevent false turn-off.
How does TO-220FPAB differ from standard TO-220AB in mounting?
TO-220FPAB features an electrically insulated metal tab (Anode-connected) molded into the plastic body, allowing direct mounting to a grounded heatsink without insulating hardware. Standard TO-220AB has a conductive tab requiring mica/silicone isolation, adding thermal resistance and assembly steps.
Is a snubber circuit required for reliable operation?
A snubber (RC network across A–K) is recommended for inductive loads or high-dV/dt environments to suppress voltage transients exceeding 600 V. While the device guarantees 5 V/µs immunity, real-world line transients may exceed this - especially in motor control or relay-switching applications.
