STMicroelectronics TN2010H-6I

Overview

TN2010H-6I from STMicroelectronics is a high-temperature, insulated-packaged SCR (silicon-controlled rectifier) rated for 20 A RMS on-state current, 600 V repetitive peak off-state voltage (VDRM/VRRM), and maximum junction temperature of 150 °C. It features 400 V/µs dV/dt immunity at 150 °C, 100 A/µs critical dI/dt, and 10 mA gate trigger current (IGT), enabling robust AC line switching in motor starters and solid-state relays.

For engineers reviewing the TN2010H-6I datasheet, TN2010H-6I pinout, TN2010H-6I application, or TN2010H-6I equivalent, key selection criteria include insulated TO-220AB package (2500 VRMS isolation), thermal resistance Rth(j-c) = 2.1 °C/W, latching current IL ≤ 60 mA, holding current IH ≤ 40 mA, and gate power dissipation PG(AV) = 1 W at 150 °C.

Technical Context

This SCR operates as a unidirectional, gate-triggered thyristor for phase-controlled AC power regulation. Its design centers on high-temperature reliability (Tj up to 150 °C), high-noise immunity (dV/dt ≥ 400 V/µs at Tj = 150 °C), and fast turn-on dynamics (dI/dt = 100 A/µs).

It uses standard DC gate triggering with IGT ≤ 10 mA and VGT ≤ 1.3 V, and maintains low on-state voltage (VTM ≤ 1.60 V at 40 A, 25 °C) and dynamic resistance (RD ≤ 17.5 mΩ at 150 °C), supporting efficient conduction in high-current, thermally constrained environments.

FAQ

What is the maximum allowable gate trigger pulse width for TN2010H-6I?

The datasheet specifies a peak gate current IGM of 4 A for tp = 20 µs at Tj = 150 °C. Pulse width must remain ≤20 µs to avoid exceeding the gate junction's thermal limits. Longer pulses require reduced amplitude per the I²t limit (162 A²s for 10 ms), but typical triggering uses <10 µs pulses at 10–20 mA to ensure reliable turn-on without gate stress.

Can TN2010H-6I be used in DC applications?

No - TN2010H-6I is a half-wave SCR designed for AC line commutation. In DC circuits, it lacks natural current-zero crossing to reset, causing latch-up unless externally forced commutated. For DC switching, use a logic-level MOSFET or IGBT with active gate control and freewheeling diode protection.

Is heatsinking required for 20 A RMS operation?

Yes - at 20 A RMS and Tc = 113 °C, the device dissipates ~1.2 W (based on VTM ≈ 1.6 V and duty cycle). With Rth(j-c) = 2.1 °C/W, a heatsink maintaining Tc ≤ 113 °C is mandatory. Without heatsinking, junction temperature exceeds 150 °C within seconds under full load.

Does the insulated TO-220AB package eliminate need for thermal interface material?

No - the insulation applies only to electrical isolation between tab and leads; thermal conduction remains essential. Thermal paste or pad is required between the metal tab and heatsink to minimize Rth(c-hs) and prevent hot-spot formation. The 2500 VRMS rating does not imply thermal decoupling.
