Product details
Overview
TN1605H-6G from STMicroelectronics is a high-temperature, 16 A RMS, 600 V repetitive peak blocking voltage silicon controlled rectifier (SCR) in D²PAK package, featuring 6 mA gate trigger current, 200 V/μs dV/dt immunity at 150 °C, and 100 A/μs critical dI/dt rating. It is designed for motorbike voltage regulators, solid-state relays, and inrush limiting where robust switching up to 150 °C junction temperature is required.
For engineers reviewing the TN1605H-6G datasheet, TN1605H-6G pinout, TN1605H-6G application, or TN1605H-6G equivalent, key selection criteria include verified 150 °C Tj operation, low IGT (6 mA max), high dV/dt (200 V/μs @ 150 °C), thermal resistance Rth(j-c) = 1.1 °C/W, and D²PAK mechanical compatibility with high-power PCB layouts.
Technical Context
This SCR uses planar passivated junction technology to sustain 600 V repetitive blocking voltage while maintaining stable triggering behavior across -40 to +150 °C. Its 6 mA maximum gate trigger current enables direct drive from low-power microcontrollers or optocouplers without external amplification.
The device achieves 200 V/μs transient immunity at full 150 °C junction temperature and supports 100 A/μs turn-on di/dt-critical for fast-switching inductive loads like motor starters and light dimmers-while maintaining latching current ≤20 mA and holding current ≤40 mA at 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - Sustains 600 V repetitive off-state voltage, enabling use in 230 V AC mains applications with safety margin. |
| IT(RMS) | 16 A @ Tc = 133 °C - Delivers 16 A continuous RMS current with heatsink mounting at case temperature ≤133 °C. |
| IGT (max) | 6 mA @ 25 °C - Low gate sensitivity allows direct interface with standard logic-level drivers or opto-TRIACs. |
| dV/dt (min) | 200 V/μs @ Tj = 150 °C - High noise immunity prevents false triggering during voltage transients in harsh environments. |
| dI/dt (critical) | 100 A/μs - Supports rapid turn-on into highly inductive loads without commutation failure. |
| Rth(j-c) | 1.1 °C/W - Enables efficient thermal transfer to heatsink; 16 A operation requires ≤17.6 W power dissipation at ΔT = 19.4 °C. |
| Tj range | -40 to +150 °C - Rated for extended high-temperature operation in engine bay or enclosed industrial enclosures. |
Pinout & Package
D²PAK (TO-263) package: surface-mount, single-ended three-terminal power package with isolated tab (anode-connected). Thermal pad on underside requires soldered copper area ≥1 cm² for rated current performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Main current input terminal | Electrically connected to metal tab; must be mounted to heatsink with electrically insulating but thermally conductive interface. |
| Cathode | Main current output terminal | Low-inductance path for load return; routed with wide copper pour to minimize switching losses. |
| Gate | Control input for triggering conduction | Receives 6 mA pulse to initiate latching; requires <1.3 V gate threshold and withstands ±5 V reverse voltage. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 150 °C-enables placement near heat sources without derating in motorbike regulator or starter circuits. |
| Low gate trigger current | Max 6 mA IGT-reduces driver component count and power consumption in compact control stages. |
| Enhanced dV/dt immunity | 200 V/μs at 150 °C-prevents spurious turn-on during EMI-rich conditions such as ignition noise in vehicle systems. |
| ECOPACK®2 compliance | Lead-free, RoHS-compliant epoxy with UL 94 V0 flammability rating-meets industrial and automotive environmental requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR-based AC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT169GW,118 | 4 A RMS, TO-92 package, 600 V VDRM, IGT = 5 mA, Tj = 125 °C max | Lower current rating and thermal capability; suitable only for signal-level or low-power switching. | Select when space-constrained PCB layout and sub-5 A loads justify trade-off in thermal headroom. |
| TYN612 | 12 A RMS, TO-220AB package, 600 V VDRM, IGT = 15 mA, Tj = 125 °C max | Higher IGT increases driver complexity; lower RMS rating limits sustained load capacity. | Choose if TO-220 mounting is preferred and 12 A RMS suffices; avoid in 150 °C ambient designs. |
Compared with BT169GW,118 and TYN612, the TN1605H-6G uniquely delivers 16 A RMS current handling with full 150 °C junction operation and industry-leading 200 V/μs dV/dt immunity-making it the only option qualified for high-temperature, high-noise motorbike and industrial starter applications.

FAQ
What is the maximum allowable case temperature for continuous 16 A RMS operation?
The datasheet specifies IT(RMS) = 16 A at Tc = 133 °C. Exceeding this case temperature requires linear derating per Figure 2; at Tc = 142 °C, maximum average current drops to 6 A. Thermal design must ensure heatsink-to-case interface resistance plus ambient rise stays within this limit.
Can TN1605H-6G be used in full-wave bridge configurations?
No-this is a single anode-cathode-gate SCR, not a bidirectional device. For full-wave AC control, two TN1605H-6G units must be connected in inverse-parallel configuration with isolated gate drives, or a dedicated TRIAC (e.g., BTA212-600B) should be selected instead.
Is the D²PAK tab electrically isolated from the cathode or anode?
The metal tab is internally connected to the anode. Electrical isolation from the heatsink is mandatory unless the heatsink is referenced to the anode potential. Use of insulating thermal pads or mica washers with silicone grease is required for safe mounting in grounded-chassis systems.
Does TN1605H-6G support snubberless operation in inductive loads?
Yes-its 200 V/μs dV/dt rating at 150 °C and 100 A/μs dI/dt capability enable snubberless operation in many motor control and relay applications. However, for loads with L/R time constants >10 ms or high-energy transients, a small RC snubber (e.g., 100 Ω + 100 nF) across anode-cathode is still recommended for long-term reliability.
