Product details
Overview
TS820-600H from STMicroelectronics is a sensitive-gate 8 A, 600 V silicon-controlled rectifier (SCR) in IPAK package, designed for precise low-current triggering (IGT ≤ 200 µA), low on-state voltage (VTM ≤ 1.6 V at 16 A), and high dV/dt immunity (≥5 V/µs at Tj = 125 °C). It serves as a crowbar protection device in DC power supplies and enables phase-controlled AC motor drives in power tools.
For engineers reviewing the TS820-600H datasheet, TS820-600H pinout, TS820-600H application, or TS820-600H equivalent, key selection criteria include gate sensitivity (200 µA max), thermal resistance (Rth(j-c) = 1.3 °C/W), repetitive peak off-state voltage (600 V), and IPAK package compatibility with medium-power PCB layouts.
Technical Context
The TS820-600H operates as a unidirectional thyristor with sensitive gate triggering (IGT ≤ 200 µA at 12 V), enabling reliable turn-on from microcontroller GPIOs without external amplification. Its holding current (IH ≤ 5 mA) and latching current (IL ≤ 6 mA) ensure stable conduction after triggering under light-load conditions.
It features a dynamic resistance of ≤46 mΩ and threshold voltage ≤0.85 V at 125 °C, supporting low conduction losses in continuous-duty applications. The device sustains 73 A non-repetitive surge current (tp = 8.3 ms) and exhibits ≥5 V/µs dV/dt immunity with RGK = 220 Ω at 125 °C - critical for noise-immune operation in switching power circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A - Sustains continuous RMS load current up to 8 A at TC = 91 °C in IPAK package |
| VDRM / VRRM | 600 V - Blocks 600 V peak reverse or off-state voltage in AC line or DC bus applications |
| IGT (max) | 200 µA - Triggers reliably from low-power logic sources (e.g., MCU I/O pins) |
| VTM (max) | 1.6 V at 16 A - Limits conduction loss to ≤25.6 W peak during surge, reducing heatsink requirements |
| dV/dt (min) | 5 V/µs at Tj = 125 °C - Resists false triggering from fast transients in motor drive or SMPS environments |
| Rth(j-c) | 1.3 °C/W - Enables efficient heat transfer to heatsink; allows ~6.2 W steady-state dissipation at ΔT = 8 °C |
| IH (max) | 5 mA - Maintains conduction down to very light loads, avoiding unintended turn-off in crowbar circuits |
Pinout & Package
TS820-600H uses the IPAK (TO-251AA) surface-mount package: three leads (anode, cathode, gate), isolated tab (anode-connected), and footprint optimized for thermal conduction via copper pad (S = 0.5 cm² recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Main current input terminal | Electrically connected to metal tab; requires insulated mounting if heatsink is grounded |
| Cathode | Main current output terminal | Low-impedance return path; connects to load ground or return rail |
| Gate | Trigger control input | Sensitive input requiring ≤200 µA pulse; must be decoupled from noise with RC snubber in high-dV/dt environments |
Key Features
| Feature | Design Value |
|---|---|
| Sensitive gate triggering | IGT ≤ 200 µA enables direct drive from 3.3 V/5 V MCUs without buffer stages |
| High dV/dt immunity | ≥5 V/µs at 125 °C ensures robust operation in noisy industrial AC control environments |
| Low on-state voltage | VTM ≤ 1.6 V at 16 A reduces conduction loss and thermal stress in sustained-load applications |
| Optimized thermal performance | Rth(j-c) = 1.3 °C/W supports >6 W continuous dissipation with minimal heatsinking |
| ECOPACK® compliance | Halogen-free molding compound and lead-free plating meet RoHS and environmental standards |
Applications
| Overvoltage Crowbar Protection | Capacitive Discharge Ignition (CDI) |
|---|---|
Use Scenario: Fast-acting short-circuit protection triggered by overvoltage detection circuitry in regulated DC power supplies. IC Role / Device Role / Timing Role: SCR acts as a sacrificial switch that latches ON to divert excess current and blow fuse, protecting downstream regulators and loads.

IC Role / Device Role / Timing Role: SCR functions as a precision-triggered switch releasing stored energy into ignition coil primary winding. Use Value: 5 mA IH guarantees reliable hold-on during brief but high-current discharge pulses; 73 A ITSM handles 8.3 ms surge. |
| Phase-Controlled Motor Drive | Inrush Current Limiting |
Use Scenario: Speed control of universal motors in cordless power tools and kitchen appliances via AC phase-angle modulation. IC Role / Device Role / Timing Role: SCR provides half-wave or full-wave controlled conduction synchronized to AC zero-crossing. Use Value: 8 A IT(RMS) supports typical 500–800 W tool motors; IPAK package allows compact, thermally efficient PCB layout. | Use Scenario: Limiting surge current during cold-start of linear power supplies or transformer-based systems. IC Role / Device Role / Timing Role: SCR bypasses NTC thermistor after warm-up, transitioning from high-resistance to low-loss conduction path. Use Value: 6 mA IL ensures clean turn-on at end of delay; 46 mΩ Rd minimizes steady-state voltage drop and self-heating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS820-600B | DPAK package (Rth(j-c) = 1.3 °C/W same), smaller footprint, lower thermal mass | Better suited for space-constrained, lower-power-density designs with limited heatsinking area | Select when PCB real estate is constrained and peak power dissipation remains <5 W |
| TS820-600T | TO-220AB through-hole package (Rth(j-c) = 1.3 °C/W), higher mechanical robustness, screw-mount compatible | Preferred for prototyping, high-vibration environments, or where manual heatsink attachment is required | Select when field serviceability, mechanical stability, or legacy TO-220 layout reuse is prioritized |
Compared with TS820-600B and TS820-600T, the TS820-600H offers identical electrical specs and thermal resistance but delivers superior surface-mount manufacturability and thermal interface consistency via its IPAK leadframe design - ideal for automated assembly of mid-power industrial controls.

FAQ
What is the maximum junction temperature for continuous operation of TS820-600H?
The TS820-600H has an operating junction temperature range of –40 °C to +125 °C. For continuous conduction, thermal design must ensure Tj does not exceed +125 °C under worst-case ambient and power dissipation conditions, using Rth(j-c) = 1.3 °C/W and appropriate heatsinking.
Can TS820-600H be driven directly by a 3.3 V microcontroller GPIO?
Yes - with IGT ≤ 200 µA and VGT ≤ 0.8 V, the TS820-600H can be triggered directly by a 3.3 V MCU GPIO using a series resistor (e.g., 10 kΩ) to limit gate current. A 100 nF gate-cathode capacitor improves noise immunity in electrically noisy environments.
Is the anode tab of TS820-600H electrically connected to the anode pin?
Yes - the metal tab is internally connected to the anode terminal. When mounted to a heatsink, electrical isolation (e.g., mica washer or insulating pad) is mandatory unless the heatsink is floating or referenced to anode potential.
Does TS820-600H require a snubber circuit in AC line applications?
A snubber (RC network across anode–cathode) is recommended for inductive loads or high-dV/dt environments to suppress voltage spikes exceeding 600 V. While the device has inherent dV/dt immunity (≥5 V/µs), snubbers prevent false triggering and improve long-term reliability in motor or transformer-driven circuits.
