STMicroelectronics TN2010H-6T

Overview

TN2010H-6T from STMicroelectronics is a high-temperature, non-isolated silicon-controlled rectifier (SCR) rated for 20 A RMS on-state current, 600 V peak off-state voltage (VDRM/VRRM), and 150 °C maximum junction temperature. It features low gate trigger current (10 mA max), high dV/dt immunity (400 V/µs at 150 °C), and robust dI/dt capability (100 A/µs), enabling use in motorbike voltage regulators and solid-state relays where thermal stress and electrical noise are critical.

For engineers reviewing the TN2010H-6T datasheet, TN2010H-6T pinout, TN2010H-6T application, or TN2010H-6T equivalent, key selection criteria include junction temperature derating, gate sensitivity under elevated Tj, RMS current handling at Tc = 132 °C, and TO-220AB thermal resistance (Rth(j-c) ≤ 1.0 °C/W).

Technical Context

This SCR operates as a unidirectional, gate-triggered power switch with latching behavior after turn-on. Its design centers on high-temperature reliability: gate triggering remains stable up to 150 °C (IGT ≤ 10 mA), dV/dt immunity is maintained at 400 V/µs even at Tj = 150 °C, and static on-state voltage is specified at both 25 °C (VTM ≤ 1.6 V) and 150 °C (VTO ≤ 0.82 V, RD ≤ 17.5 mΩ).

Thermal performance is defined by Rth(j-c) ≤ 1.0 °C/W and IT(RMS) = 20 A at Tc = 132 °C, requiring direct heatsink mounting to the TO-220AB case. The device supports fast switching with typical turn-on time of 1.9 µs and turn-off time of 70 µs under specified test conditions (ITM = 40 A, dI/dt = 30 A/µs).

Key Specifications

Pinout & Package

Packaged in a non-isolated TO-220AB case with three terminals: Anode (A), Cathode (K), and Gate (G). The package requires mechanical mounting via M3 screw (0.4–0.6 N·m torque) to a heatsink for thermal management; no electrical isolation between case and Anode.

FAQ

Is TN2010H-6T electrically isolated in its TO-220AB package?

No. The TN2010H-6T uses a non-isolated TO-220AB package where the metal tab (case) is internally connected to the Anode terminal. Electrical isolation must be achieved externally via insulating washers and bushings if required in the application layout.

What is the minimum gate trigger voltage required at 150 °C junction temperature?

The datasheet specifies VGT ≤ 1.3 V (maximum) at Tj = 25 °C, but does not define a minimum VGT at 150 °C. However, Figure 5 shows VGT decreases with rising Tj; typical VGT at 150 °C is ~0.8 V. Designers should ensure gate drive sources can deliver ≥1.3 V to guarantee turn-on across full temperature range.

Can TN2010H-6T replace a TRIAC in AC phase-control applications?

No. TN2010H-6T is a unidirectional SCR and conducts only during one half-cycle of AC. For full-wave phase control (e.g., light dimmers), two SCRs in anti-parallel or a single TRIAC are required. Using one SCR results in half-wave rectified output and increased harmonic distortion.

How does the 100 A/µs dl/dt rating impact PCB layout?

The 100 A/µs dl/dt rating demands low-inductance gate and main current paths. Layout must minimize loop area between Anode–Cathode and Gate–Cathode traces, use short wide traces, and avoid vias in high-di/dt paths. Poor layout may cause false turn-on or oscillation during rapid current rise.
