STMicroelectronics TN1610H-6T

Overview

TN1610H-6T from STMicroelectronics is a 600 V, 16 A RMS sensitive-gate silicon-controlled rectifier (SCR) in a non-isolated TO-220AB package, rated for continuous operation up to 150 °C junction temperature, with dV/dt immunity of 1000 V/µs at Tj = 150 °C and IGT = 10 mA. It is engineered for robust motorbike voltage regulator circuits, solid-state relays, and inrush current limiting in industrial power tools.

For engineers reviewing the TN1610H-6T datasheet, TN1610H-6T pinout, TN1610H-6T application, or TN1610H-6T equivalent, key selection criteria include its high thermal capability (Tj = 150 °C), fast turn-on dI/dt (100 A/µs), low on-state voltage (VTM ≤ 1.60 V @ 32 A), gate sensitivity (IGT ≤ 10 mA), and ECOPACK®2 compliance for environmental design requirements.

Technical Context

This SCR employs planar passivated junction technology to sustain repetitive off-state voltages up to 600 V (VDRM/VRRM) while maintaining stable triggering behavior across -40 °C to +150 °C. Its latching current (IL ≤ 60 mA) and holding current (IH ≤ 30 mA) are optimized for reliable turn-on and sustained conduction under high-temperature, high-noise conditions.

The device's thermal resistance (Rth(j-c) ≤ 1.1 °C/W) enables 16 A RMS conduction at Tc = 133 °C without external heatsink derating, and its dV/dt immunity remains ≥1000 V/µs even at maximum junction temperature-critical for crowbar protection and phase-controlled motor starters where transient noise is prevalent.

FAQ

What is the maximum case temperature for continuous 16 A RMS operation?

The TN1610H-6T sustains 16 A RMS continuous conduction at Tc = 133 °C, as specified in Table 1 of DS10821 Rev 2. Operation above this temperature requires derating per Figure 2; at Tc = 142 °C, IT(AV) drops to 6 A. Thermal design must ensure case temperature remains within this limit under worst-case ambient and airflow conditions.

Can TN1610H-6T be used in zero-crossing AC switching applications?

Yes-its dV/dt immunity (≥1000 V/µs at 150 °C) and controlled turn-on characteristics make it suitable for zero-crossing switched-mode AC control when paired with appropriate optocoupler drivers (e.g., MOC3063). Gate triggering must occur within ±15° of zero-crossing to minimize EMI and ensure repeatable conduction angle.

Is the TO-220AB package electrically insulated?

No-the TO-220AB package used for TN1610H-6T is non-isolated; the metal tab (anode) is electrically connected to the anode terminal. Electrical isolation must be achieved externally using insulating washers and shoulder washers during mounting, especially when the heatsink is grounded or at a different potential.

What is the typical turn-on time (tgt) and how does it vary with temperature?

Tgt is 1.9 µs typical at IT = 32 A, VD = 600 V, IG = 100 mA, and (dIG/dt)max = 0.2 A/µs (Table 2). It increases slightly with rising junction temperature due to carrier lifetime effects, but remains sub-3 µs across the full -40 °C to +150 °C range-ensuring consistent timing in phase-control circuits.
