Product details
Overview
TN2015H-6T from STMicroelectronics is a high-temperature, non-isolated silicon-controlled rectifier (SCR) rated for 20 A RMS on-state current at Tc = 132 °C, with 600 V repetitive peak off-state voltage (VDRM/VRRM), 15 mA maximum gate triggering current (IGT), and 750 V/µs dV/dt immunity up to 150 °C junction temperature - used in motorbike voltage regulators and solid-state relays.
For engineers reviewing the TN2015H-6T datasheet, TN2015H-6T pinout, TN2015H-6T application, or TN2015H-6T equivalent, key selection criteria include thermal performance at 150 °C junction, robust dV/dt noise immunity, gate sensitivity, surge current capability (197 A @ 8.3 ms), and TO-220AB package mounting requirements.
Technical Context
The TN2015H-6T is a four-layer p-n-p-n thyristor with controlled turn-on via gate-triggered regenerative latching. Its design emphasizes high-temperature reliability: junction-to-case thermal resistance is 1.0 °C/W, enabling 20 A RMS conduction at 132 °C case temperature.
It features a low dynamic on-state resistance (Rd ≤ 17.5 mΩ at Tj = 150 °C) and threshold voltage (Vt0 ≤ 0.82 V), supporting efficient power switching in phase-controlled AC circuits. Gate drive is optimized for low IGT (≤15 mA) while maintaining high dV/dt immunity (≥750 V/µs at 150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 600 V - supports mains-connected AC control up to 400 V RMS systems with safety margin. |
| IT(RMS) | 20 A at Tc = 132 °C - enables compact heatsink design in motorbike regulators and SSRs. |
| IGT (max) | 15 mA - allows direct drive from microcontrollers or low-power optocouplers without amplification. |
| dV/dt (min) | 750 V/µs at Tj = 150 °C - prevents false triggering in noisy industrial environments. |
| dI/dt (min) | 100 A/µs - ensures reliable turn-on under high di/dt loads like motor inrush or transformer energization. |
| Rth(j-c) | 1.0 °C/W - permits effective thermal coupling to heatsinks for sustained 20 A operation. |
| ITSM (8.3 ms) | 197 A - handles short-circuit surges in motor starters and crowbar protection circuits. |
Pinout & Package
Package: Non-isolated TO-220AB (3-lead, vertical mount, screw-hole tab). Tab is anode (A); leads are cathode (K) and gate (G). Mounting torque: 0.4–0.6 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (metal surface) | Anode (A) | Primary current path input; electrically connected to heatsink - requires insulating washer if isolation needed. |
| Lead 1 (left, viewed front) | Cathode (K) | Current return path; must be routed with low-inductance layout for stable commutation. |
| Lead 2 (right, viewed front) | Gate (G) | Low-energy trigger input; sensitive to EMI - requires local RC snubber and short trace routing. |
Key Features
| Feature | Design Value |
|---|---|
| 150 °C max junction temperature | Enables operation in engine-bay environments (e.g., motorbike regulators) without derating. |
| 750 V/µs dV/dt immunity at 150 °C | Eliminates need for external gate snubbers in high-noise motor control applications. |
| 100 A/µs critical dI/dt rating | Supports fast turn-on into inductive loads like universal motors and solenoids. |
| ECOPACK®2 compliance | Meets RoHS, halogen-free, and lead-free soldering requirements for industrial and automotive use. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR-based AC control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BT139-600E | Lower Tj max (125 °C), higher IGT (50 mA), same VDRM (600 V), TO-220 package. | Not suitable for >125 °C ambient environments; requires stronger gate drive. | Select only where thermal environment is controlled and gate drive capability exceeds 50 mA. |
| TYN612 | Same VDRM (600 V), lower IT(RMS) (12 A), Tj max = 125 °C, TO-220 package. | Limited to lower-current applications; insufficient for 20 A motorbike regulator duty. | Acceptable only for light-duty dimmers or SSRs below 12 A RMS load. |
Compared with BT139-600E and TYN612, the TN2015H-6T delivers superior thermal headroom (150 °C vs. 125 °C), lower gate drive demand (15 mA vs. ≥50 mA), and higher surge tolerance - making it uniquely suited for high-reliability, high-temperature motor control and regulator designs.

FAQ
Is the TN2015H-6T electrically isolated?
No. The TN2015H-6T uses a non-isolated TO-220AB package: the metal tab is internally connected to the anode. Electrical isolation must be achieved externally using insulating washers and bushings when mounting to a heatsink.
What is the minimum gate trigger pulse width required?
The datasheet specifies gate triggering under standardized test conditions (RL = 33 Ω, VD = 12 V), but does not define a minimum pulse width. Practical designs use ≥10 µs pulses to ensure reliable latching, especially at elevated junction temperatures.
Can TN2015H-6T replace TN2015-600 in existing designs?
Yes - the TN2015H-6T is a direct upgrade: identical pinout and VDRM, but with enhanced 150 °C junction rating (vs. 125 °C) and improved dV/dt immunity (750 V/µs vs. 500 V/µs), enabling higher reliability in thermally stressed applications.
Does TN2015H-6T support zero-crossing switching?
No. As a standard SCR, it conducts until current falls below holding current (IH ≤ 50 mA). Zero-crossing functionality requires external circuitry - typically a zero-crossing detector IC driving the gate synchronously with AC line zero crossings.
