Product details
Overview
TN1605H-6FP from STMicroelectronics is a high-temperature, insulated-packaged silicon controlled rectifier (SCR) rated for 16 A RMS on-state current at 83 °C case temperature, 600 V repetitive peak off-state voltage (VDRM/VRRM), and 6 mA gate triggering current (IGT). It operates up to 150 °C junction temperature and delivers 100 A/µs critical dI/dt with 200 V/µs dV/dt immunity at Tj = 150 °C, enabling robust motor control in power tools and solid-state relays.
For engineers reviewing the TN1605H-6FP datasheet, TN1605H-6FP pinout, TN1605H-6FP application, or TN1605H-6FP equivalent, key selection criteria include insulated TO-220FPAB package voltage rating (2000 VRMS), thermal resistance (Rth(j-c) = 4.5 °C/W), and high-noise-immunity triggering behavior under elevated temperature.
Technical Context
The TN1605H-6FP is a unidirectional thyristor designed for phase-controlled AC power switching. Its insulated TO-220FPAB package enables back-to-back configuration without external isolation, supporting crowbar protection and inrush limiting where galvanic separation is required.
It features a low threshold voltage (Vt0 ≤ 0.82 V at 150 °C) and dynamic resistance (Rd ≤ 25 mΩ), ensuring minimal conduction loss at high current. Gate sensitivity (IGT ≤ 6 mA) and high dV/dt immunity (≥200 V/µs at 150 °C) allow direct drive from microcontrollers or optocouplers without snubbers in many industrial loads.
Key Specifications

Applications
| Motorbike Voltage Regulator | Inrush Current Limiter |
|---|---|
Use Scenario: Regulates alternator output in 12 V motorcycle charging systems under variable engine speed and load. IC Role / Device Role / Timing Role: SCR acts as phase-controlled shunt regulator, dissipating excess energy as heat when battery is fully charged. Use Value: High Tj rating (150 °C) ensures reliability in engine-bay mounting; insulated package simplifies heatsink integration near chassis ground. | Use Scenario: Limits inrush current during cold start of induction motors and transformer-fed power supplies. IC Role / Device Role / Timing Role: SCR is triggered after zero-crossing delay to ramp voltage gradually across load. Use Value: 100 A/µs dI/dt supports fast, controlled turn-on without oscillation; 600 V blocking handles 230 VAC + transients. |
| Motor Starter (Power Tools) | Solid-State Relay |
Use Scenario: Enables soft-start and overcurrent-protected activation of universal motors in corded drills and grinders. IC Role / Device Role / Timing Role: SCR serves as main power switch, gated by microcontroller-based timing circuit for precise dwell control. Use Value: Low IGT (6 mA) allows direct MCU GPIO drive; TO-220FPAB isolation avoids separate optocoupler for floating gate bias. | Use Scenario: Replaces electromechanical relays in HVAC controllers and industrial PLC outputs. IC Role / Device Role / Timing Role: SCR functions as zero-voltage-switched AC power switch, triggered via optocoupler-isolated gate signal. Use Value: 2000 VRMS insulation enables direct mains connection without auxiliary isolation; ECOPACK®2 compliance meets RoHS and halogen-free requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR-based AC power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT139-600E | Non-insulated TO-220 package; lower dV/dt (100 V/µs at 125 °C); IGT = 15 mA | Requires insulating hardware for floating mounting; less suitable for back-to-back or high-EMI environments | Select when cost is primary and isolation can be added externally |
| TYN616RG | Insulated TO-220AB package (2500 VRMS); same 600 V rating; IGT = 15 mA; Tj max = 125 °C | Higher isolation voltage but reduced thermal capability limits RMS current in compact heatsinks | Select when higher isolation is needed but ambient temperature stays below 85 °C |
Compared with BT139-600E and TYN616RG, the TN1605H-6FP uniquely balances 150 °C operation, 200 V/µs dV/dt at full temperature, and 6 mA gate sensitivity - making it optimal for thermally constrained, noise-prone motor control where both reliability and drive simplicity matter.

FAQ
What is the maximum allowable case temperature for continuous 16 A RMS operation?
The TN1605H-6FP supports 16 A RMS only at Tc = 83 °C per datasheet Table 2. At higher case temperatures (e.g., 102 °C), IT(RMS) derates to 8 A. Thermal design must ensure case temperature remains at or below 83 °C under worst-case ambient and airflow conditions to sustain full rated current.
Can the TN1605H-6FP be used in a back-to-back configuration without external isolation?
Yes. The TO-220FPAB package provides 2000 VRMS insulation between the tab and all terminals, enabling direct back-to-back mounting on a common heatsink without insulating hardware. This configuration is validated in ST application notes for AC phase control and bidirectional switching.
Is a snubber circuit required for reliable operation at 230 VAC?
A snubber is not mandatory due to the device's 200 V/µs dV/dt rating at 150 °C, which exceeds typical 230 VAC transient slew rates. However, a small RC snubber (e.g., 100 Ω + 100 nF) is recommended for highly inductive loads or long cable runs to suppress voltage spikes during commutation.
Does the TN1605H-6FP meet RoHS and REACH requirements?
Yes. The device is ECOPACK®2 compliant, meaning it is lead-free, halogen-free, and conforms to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and compliance documentation are available via ST's official product page and quality portal.
