STMicroelectronics TN2010H-6G

Overview

TN2010H-6G from STMicroelectronics is a high-temperature, 20 A RMS, 600 V peak SCR in D²PAK package, designed for robust AC power control in thermally demanding environments. It delivers 100 A/µs dI/dt turn-on capability, 400 V/µs dV/dt noise immunity at 150 °C junction temperature, and 10 mA gate trigger current - enabling compact, reliable motorbike voltage regulators and solid-state relays.

For engineers reviewing the TN2010H-6G datasheet, TN2010H-6G pinout, TN2010H-6G application, or TN2010H-6G equivalent, key selection criteria include its 150 °C max junction rating, D²PAK thermal performance (R_th(j-c) = 1.0 °C/W), 600 V off-state blocking, and gate sensitivity under elevated temperature - critical for inrush limiting and phase-controlled dimming circuits.

Technical Context

This SCR operates as a unidirectional thyristor with latching behavior triggered by a low-energy gate pulse (IGT ≤ 10 mA). Its design centers on high-temperature reliability: rated for continuous operation up to T_j = 150 °C, with dV/dt immunity maintained at full temperature and I²t = 162 A²s for 10 ms surges.

The device uses a planar passivated silicon structure optimized for ruggedness in repetitive surge conditions. Gate triggering is specified with RL = 33 Ω load and V_D = 12 V, and turn-off is achieved by natural current zero-crossing or forced commutation - no active gate turn-off capability.

Key Specifications

Pinout & Package

The TN2010H-6G is housed in a surface-mount D²PAK (TO-263) package with three terminals: Anode (A), Cathode (K), and Gate (G). The exposed metal tab is electrically connected to the Anode and serves as the primary thermal path to the PCB copper pour or heatsink.

FAQ

What is the maximum allowable case temperature for continuous 20 A RMS operation?

The TN2010H-6G sustains 20 A RMS only when case temperature (T_c) is held at or below 132 °C, as specified in Table 2. Exceeding this temperature requires derating per Figure 2; at T_c = 140 °C, maximum IT(AV) drops to 8 A. Thermal design must ensure R_th(j-c) ≤ 1.0 °C/W and adequate copper area under the tab.

Can TN2010H-6G be used in DC circuits?

Yes, but only in applications where current naturally falls below the holding current (I_H ≤ 40 mA) to allow turn-off - such as pulsed loads or circuits with active commutation. It cannot self-commutate in steady-state DC; forced commutation or series switch interruption is required to reset conduction.

Is a snubber circuit required for reliable operation?

A snubber is recommended when driving inductive loads or operating near V_DRM limits, especially where dV/dt exceeds 400 V/µs. While the device tolerates 400 V/µs at 150 °C, real-world transients (e.g., relay bounce, transformer saturation) may exceed this - a standard RC snubber (e.g., 100 Ω + 100 nF) improves margin and longevity.

How does gate trigger sensitivity change with junction temperature?

IGT decreases as T_j rises: Figure 5 shows I_GT at 150 °C is ~60% of its 25 °C value. At 150 °C, typical I_GT is ~5 mA (max 10 mA), meaning gate drive remains effective but less sensitive - designs should verify triggering at worst-case cold start (–40 °C) and hot steady state (+150 °C).
