Product details
Overview
TN1625-600G from STMicroelectronics is a 16 A, 600 V RMS standard silicon-controlled rectifier (SCR) in D2PAK package, with 25 mA gate trigger current and 50 A/µs critical dI/dt rating. It delivers robust surge capability (200 A non-repetitive, 8.3 ms), low on-state voltage (1.6 V at 32 A), and thermal resistance of 1.1 °C/W (junction-to-case), suited for AC power control in industrial motor starters and lighting dimmers.
For engineers reviewing the TN1625-600G datasheet, TN1625-600G pinout, TN1625-600G application, or TN1625-600G equivalent, key selection criteria include verified VDRM/VRRM (600 V), IT(RMS) (16 A), IGT (25 mA max), dI/dt (50 A/µs), and Rth(j-c) (1.1 °C/W) - all confirmed per ST's November 2007 Rev 6 datasheet.
Technical Context
This SCR operates as a unidirectional, gate-triggered thyristor for phase-controlled AC switching. Its design supports 180° conduction-angle operation with 10 A average on-state current at Tc = 110 °C and withstands repetitive surges up to 190 A (10 ms) at Tj = 25 °C.
Gate triggering is specified at VD = 12 V with 33 Ω load, requiring ≤25 mA IGT and ≤1.3 V VGT. Holding current remains ≤40 mA (gate open), and latching current ≤60 mA, ensuring reliable turn-on and stable conduction under varying junction temperatures (–40 to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - blocking voltage rating ensures safe operation in 230 VAC mains-fed circuits with margin. |
| IT(RMS) | 16 A - continuous RMS current handling enables use in 2 kW resistive loads at 230 VAC. |
| IGT (max) | 25 mA - gate sensitivity allows direct drive from microcontroller GPIO or low-power optocouplers. |
| dI/dt (critical) | 50 A/µs - high commutation immunity prevents false triggering during fast-rising load currents. |
| Rth(j-c) | 1.1 °C/W - low thermal resistance supports high-power dissipation with minimal heatsink requirement. |
| VTM (max) | 1.6 V at 32 A - low on-state drop reduces conduction losses and thermal stress in sustained-load applications. |
| I²t (fusing) | 180 A²s - quantifies single-pulse surge energy tolerance, critical for short-circuit protection coordination. |
Pinout & Package
The TN1625-600G uses the D2PAK (TO-263) surface-mount package with isolated tab, rated for 1.1 °C/W junction-to-case thermal resistance and UL94 V0 epoxy molding. Mounting torque: 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Carries full load current into device; electrically connected to metal tab for thermal path. |
| Cathode (K) | Main current exit terminal | Completes main conduction path; PCB trace must handle ≥16 A RMS continuously. |
| Gate (G) | Trigger control input | Receives low-energy pulse (≤25 mA, ≤1.3 V) to initiate conduction; requires noise filtering in noisy environments. |
Key Features
| Feature | Design Value |
|---|---|
| Surge current rating | 200 A (8.3 ms) - enables reliable operation during motor inrush or lamp cold-start events. |
| Low dynamic resistance | 23 mΩ at Tj = 125 °C - minimizes on-state power loss and improves thermal efficiency at elevated temperatures. |
| High dV/dt immunity | 500 V/µs (Tj = 125 °C) - suppresses false triggering from line transients or inductive kickback. |
| ECOPACK® compliance | Lead-free second-level interconnect - meets RoHS and JEDEC JESD97 environmental requirements. |
Applications
| Industrial Motor Starters | AC Lighting Dimmers |
|---|---|
Use Scenario: Phase-angle controlled start-up of 1.5 kW induction motors in HVAC blowers and conveyor drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR-based AC power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TYN616RG | Same 16 A/600 V rating but TO-220AB through-hole package; higher Rth(j-a) (60 °C/W vs. 45 °C/W for D2PAK). | Preferred for prototyping or low-volume assemblies where manual soldering or heatsink clamping is used. | Select when board assembly favors through-hole mounting or when existing TO-220 footprint is fixed. |
| BT169G | Lower IT(RMS) (0.8 A), smaller SOT-89 package; not a direct replacement - differs by >20× current rating and package thermal performance. | Only suitable for signal-level triggering or auxiliary control, not main power switching. | Avoid for power-switching roles; consider only for gate driver interface or logic-level isolation stages. |
Compared with TYN616RG and BT169G, TN1625-600G offers superior thermal performance in surface-mount designs and true 16 A power-handling capability - making it the sole viable choice for high-density, high-current AC control where D2PAK mounting and 1.1 °C/W Rth(j-c) are required.

FAQ
What is the maximum junction temperature for continuous operation?
The TN1625-600G has an operating junction temperature range of –40 °C to +125 °C. For continuous RMS current operation at 16 A, case temperature must be maintained at ≤110 °C per absolute ratings table; derating applies above this point based on thermal resistance and heatsink performance.
Can TN1625-600G be used in DC circuits?
No - this is a standard (non-reverse-conducting) SCR designed exclusively for AC or pulsating unidirectional applications. It cannot block reverse voltage or commutate in DC; forced-commutation or external circuitry would be required, which is outside its specified operating conditions and not supported by ST's characterization.
Is a snubber circuit required for reliable operation?
A snubber (RC network across A–K) is recommended when switching inductive loads or in environments with high dV/dt transients. Although the device specifies 500 V/µs dV/dt immunity at 125 °C, real-world line noise and transformer leakage may exceed this - especially in motor or solenoid control - so a properly sized snubber improves long-term reliability.
What is the gate trigger voltage threshold?
VGT is guaranteed ≤1.3 V at Tj = 25 °C with IGT = 25 mA test condition. At elevated temperatures, VGT decreases slightly; typical values range from 0.7 V to 1.1 V across the full –40 °C to +125 °C junction range, per Figure 5 in the datasheet.
