Product details
Overview
TN1625-600G-TR from STMicroelectronics is a 16 A, 600 V RMS standard silicon-controlled rectifier (SCR) in D2PAK package, with 25 mA gate trigger current (IGT), 1.6 V on-state voltage (VTM) at 32 A, and 50 A/µs critical dI/dt rating. It is designed for AC line control in industrial motor starters, lighting dimmers, and solid-state relays requiring robust surge immunity and clip-assembly thermal performance.
For engineers reviewing the TN1625-600G-TR datasheet, TN1625-600G-TR pinout, TN1625-600G-TR application, or TN1625-600G-TR equivalent, key selection criteria include RMS current derating at case temperature, I²t fusing capability (180 A²s), gate sensitivity stability over junction temperature, and D2PAK thermal resistance (1.1 °C/W junction-to-case).
Technical Context
This SCR operates as a unidirectional latching switch triggered by a positive gate pulse relative to cathode. Conduction initiates when anode-to-cathode voltage exceeds VDRM (600 V) and gate current exceeds IGT (25 mA max), sustaining conduction until current falls below holding current (IH ≤ 40 mA). It features a dynamic resistance of 23 mΩ and threshold voltage of 0.77 V at 125 °C.
Designed for 50/60 Hz AC phase control, it supports non-repetitive surge peaks up to 200 A (8.3 ms) and exhibits minimum dV/dt immunity of 500 V/µs at 125 °C with gate open - critical for noise-immune operation in EMI-prone industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A - maximum continuous RMS on-state current at 110 °C case temperature, defining steady-state power handling in AC mains switching |
| VDRM / VRRM | 600 V - peak repetitive off-state blocking voltage, setting maximum AC line voltage compatibility (e.g., 230 VAC + margin) |
| IGT | 25 mA max - maximum gate trigger current required at 12 V, determining driver circuit strength and optocoupler selection |
| VTM | 1.6 V max at 32 A - on-state voltage drop during conduction, directly impacting power loss (P = VTM × ITM) and heatsink sizing |
| I²t | 180 A²s - fusing integral for 10 ms surge, used to coordinate with upstream fuse selection for short-circuit protection |
| Rth(j-c) | 1.1 °C/W - junction-to-case thermal resistance, enabling accurate junction temperature calculation (Tj = Tc + P × Rth(j-c)) |
| dI/dt | 50 A/µs - minimum critical rate-of-rise of on-state current, limiting allowable inrush in inductive loads without false turn-on |
Pinout & Package
The TN1625-600G-TR uses a surface-mount D2PAK (TO-263) package with three terminals: Anode (A), Cathode (K), and Gate (G). The metal tab is electrically connected to the Anode and serves as the primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A (Anode) | Main power input terminal | Connected to AC line or load side; tab is electrically tied to A and must be isolated from heatsink unless referenced to same potential |
| K (Cathode) | Main power output terminal | Reference node for gate drive; all gate signals are measured relative to K; carries full load current return path |
| G (Gate) | Control input terminal | Receives low-energy triggering pulse; requires series resistor to limit IGM (4 A peak) and ensure reliable turn-on without overstress |
Key Features
| Feature | Design Value |
|---|---|
| Clip-assembly construction | Enables 200 A non-repetitive surge current (8.3 ms), exceeding standard TO-220 SCRs by >25% for motor start-up stress tolerance |
| ECOPACK® lead-free packaging | Complies with JEDEC JESD97; second-level interconnect is lead-free and marked on package for RoHS-compliant manufacturing |
| High dV/dt immunity | 500 V/µs minimum at 125 °C ensures stable blocking under fast transients common in industrial AC lines with contactor switching |
| Low dynamic resistance | 23 mΩ at 125 °C reduces conduction loss drift over temperature, improving thermal stability in sustained-load applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TYN616RG | TO-220AB package; identical 16 A/600 V ratings but higher Rth(j-a) (60 °C/W vs. 45 °C/W for D2PAK); 25 mA IGT | Through-hole mounting; less efficient natural convection cooling; requires larger heatsink for same power dissipation | Select when board assembly uses through-hole process or mechanical retention demands screw-mount package |
| BT169GW | 4 A IT(RMS); smaller SOT-82 package; 50 mA IGT; lower VDRM (400 V); not clip-assembled | Not suitable for 16 A loads; limited surge capability (25 A); intended for signal-level or low-power switching | Reject for direct replacement; only consider for redesign where load current < 4 A and space constraints prohibit D2PAK |
Compared with TYN616RG and BT169GW, the TN1625-600G-TR delivers superior thermal performance in surface-mount designs, higher surge robustness for motor loads, and tighter gate sensitivity - making it optimal for high-reliability industrial AC control where D2PAK footprint and thermal efficiency are prioritized.

FAQ
What is the maximum junction temperature for continuous operation?
The TN1625-600G-TR has an operating junction temperature range of –40 °C to +125 °C. For continuous conduction, Tj must not exceed +125 °C; this is enforced by limiting IT(RMS) to 16 A at Tc = 110 °C, with derating curves provided in Figure 2 of the datasheet for lower case temperatures.
Can this SCR be used in DC circuits?
No - the TN1625-600G-TR is a standard (non-self-commutated) SCR and cannot be turned off by gate control in DC applications. It requires external commutation (e.g., forced current reversal or auxiliary circuit) to reset conduction, making it unsuitable for pure DC switching without added complexity.
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 (>500 V/µs), even though the device specifies 500 V/µs minimum dV/dt immunity. This mitigates risk of false triggering due to junction temperature rise or aging effects beyond initial characterization.
What is the gate drive requirement for reliable turn-on at elevated temperature?
At Tj = 125 °C, IGT increases to ~2× its 25 °C value (≈50 mA), per Figure 5. To ensure margin, gate drive must deliver ≥75 mA peak into the specified test circuit (VD = 12 V, RL = 33 Ω), achievable with a 100 Ω series resistor and 12 V source - verified in ST's application note AN267.
