STMicroelectronics TN1610H-6FP

Overview

TN1610H-6FP from STMicroelectronics is a 600 V, 16 A RMS insulated-gate thyristor (SCR) in TO-220FPAB package, rated for 150 °C junction operation. It delivers high noise immunity (dV/dt = 1000 V/µs at 150 °C), low gate trigger current (IGT = 10 mA), and robust turn-on di/dt capability (100 A/µs), enabling compact, thermally stable voltage regulator circuits in motorbike alternators.

For engineers reviewing the TN1610H-6FP datasheet, TN1610H-6FP pinout, TN1610H-6FP application, or TN1610H-6FP equivalent, key selection criteria include insulated package voltage rating (2000 V_RMS), thermal resistance (R_th(j-c) = 4.5 °C/W), peak surge current (153 A), on-state voltage (V_TM ≤ 1.60 V @ 32 A), and dV/dt immunity across full temperature range.

Technical Context

This SCR operates as a latching, unidirectional power switch with gate-controlled turn-on and natural commutation. Its design integrates high-temperature silicon (T_j up to 150 °C), optimized gate structure for low I_GT, and rugged junction layout to sustain 100 A/µs di/dt without false triggering.

The TO-220FPAB package provides reinforced insulation (2000 V_RMS, 1 min), enabling back-to-back configuration in AC control applications. Thermal performance is defined by R_th(j-c) = 4.5 °C/W and derated IT(AV) of 6 A at T_c = 117 °C, supporting high-power density designs in constrained thermal environments.

FAQ

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

The datasheet specifies I_T(RMS) = 16 A at T_c = 83 °C. Exceeding this case temperature requires linear derating per Figure 2: at T_c = 102 °C, maximum RMS current drops to 8 A; at T_c = 117 °C, it falls to 6 A. Thermal design must ensure heatsink interface maintains T_c ≤ 83 °C under worst-case ambient and airflow conditions.

Can TN1610H-6FP be used in back-to-back configuration for full AC wave control?

Yes-the TO-220FPAB package provides 2000 V_RMS insulation between case and terminals, enabling safe mechanical mounting of two devices on a common heatsink with opposite anode/cathode orientation. This configuration supports true AC switching without additional isolation hardware, as confirmed in ST's application guidance for solid-state relays.

Is a snubber circuit required for reliable operation in motor control applications?

A snubber is not mandatory due to the device's 1000 V/µs dV/dt rating at 150 °C, which exceeds typical triac/SCR snubber thresholds. However, in highly inductive loads (e.g., large contactor coils), a small RC snubber (e.g., 100 Ω + 100 nF) across A–K may improve longevity by limiting voltage overshoot during commutation-per ST AN437 application note recommendations.

What is the minimum gate trigger pulse width needed for reliable turn-on at 150 °C junction temperature?

The datasheet does not specify minimum pulse width, but gate triggering is validated with 20 µs pulses (I_GM test condition). For robust operation at T_j = 150 °C, ST recommends ≥100 µs pulses to ensure full latch-on before gate signal removal, especially under high di/dt or elevated temperature where latching current (I_L) rises to 60 mA max.
