Product details
Overview
TN3050HP-12L2Y from STMicroelectronics is an AEC-Q101 qualified automotive-grade SCR thyristor rated for 30 ARMS continuous conduction, 1200 V repetitive off-state voltage (VDRM/VRRM), and 1400 V non-repetitive peak blocking voltage (VDSM/VRSM), with 50 mA max gate trigger current and 150 °C maximum junction temperature - deployed in on-board battery chargers and 3-phase motor soft-start control.
For engineers reviewing the TN3050HP-12L2Y datasheet, TN3050HP-12L2Y pinout, TN3050HP-12L2Y application, or TN3050HP-12L2Y equivalent, key selection criteria include dV/dt immunity (1000 V/µs at Tj = 150 °C), surge capability (300 A @ 10 ms), thermal resistance (0.8 °C/W j-c), gate sensitivity (IGT ≤ 50 mA), and HU3PAK surface-mount package compatibility with top-side cooling.
Technical Context
This SCR operates as a unidirectional, gate-controlled power switch requiring positive gate pulse to initiate conduction; it latches ON until current falls below holding level (IH ≤ 100 mA) and sustains blocking in both directions up to ±1200 V at 150 °C junction temperature.
Its high dV/dt immunity (min. 1000 V/µs) and critical rate of rise of on-state current (dl/dt ≥ 200 A/µs) enable robust operation in noisy industrial AC line environments; the 0.88 V threshold voltage (VTO) and 14 mΩ dynamic resistance (RD) support low conduction losses at 60 A peak current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 30 A - Sustained RMS current handling at TC = 126 °C, enabling 42 A RMS AC switching in dual back-to-back configuration |
| VDRM / VRRM | 1200 V - Repetitive peak off-state voltage rating, suitable for 690 VAC three-phase systems with safety margin |
| dV/dt (min) | 1000 V/µs - Immunity to false triggering from fast transient voltage spikes in motor drive or inverter applications |
| IGT (max) | 50 mA - Maximum gate trigger current required, defining compatible driver strength and isolation requirements |
| Rth(j-c) | 0.8 °C/W - Junction-to-case thermal resistance, supporting >35 W power dissipation with moderate heatsinking |
| ITSM (10 ms) | 300 A - Non-repetitive surge current rating, allowing inrush current limiting during AC-DC rectifier startup |
| VTO / RD | 0.88 V / 14 mΩ - Low conduction loss profile at Tj = 150 °C, reducing thermal stress in high-duty-cycle battery charger stages |
Pinout & Package
Supplied in HU3PAK surface-mount package: 3-terminal, top-side cooled, epoxy-molded, lead-free, UL94 V0 compliant. Dimensions: 11.8 × 14.0 × 18.6 mm (L × W × H), with 7×0.90 mm and 6×1.27 mm solder pads per footprint drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main power input terminal | Carries full load current into device; requires low-inductance layout and thermal pad connection for conduction and heat extraction |
| Cathode (K) | Main power output terminal | Completes main current path; electrically and thermally tied to PCB copper area for low Rth(j-c) performance |
| Gate (G) | Control input terminal | Accepts TTL/CMOS-compatible trigger pulse; sensitive to ESD and noise - requires localized filtering and short trace routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SCR switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06D | 600 V VRRM, 30 A IF, fast recovery diode - not gate-controllable, no latching behavior | Replaces only in freewheeling or uncontrolled rectification roles; cannot substitute for phase control or AC switching | Select only when bidirectional blocking and gate-triggered turn-on are unnecessary |
| TT330N16KOF | 1600 V VRRM, 330 A ITSM, TO-240AA package - larger footprint, higher thermal mass, 3× gate drive requirement | Suitable for high-power industrial UPS but incompatible with compact SMD layouts and automotive space constraints | Choose only for >100 kW systems where HU3PAK size and weight are prohibitive |
Compared with STTH30L06D and TT330N16KOF, TN3050HP-12L2Y uniquely balances automotive qualification, SMD manufacturability, 1200 V blocking, and 30 A RMS in a single HU3PAK package - making it irreplaceable for space-constrained, high-reliability AC power control where gate control and compactness are mandatory.

FAQ
What is the maximum allowable gate trigger pulse width for TN3050HP-12L2Y?
The datasheet specifies a peak forward gate current (IGM) of 8 A with pulse width ≤20 µs. For reliable triggering without gate damage, ST recommends gate pulses ≤10 µs at 50–100 mA, aligned with the 1 µs typical turn-on delay (tgt). Longer pulses increase risk of gate metallization failure, especially above 150 °C junction temperature.
Can TN3050HP-12L2Y be used in bidirectional AC switching applications?
No - TN3050HP-12L2Y is a unidirectional SCR and blocks voltage only in reverse direction up to VRRM = 1200 V, but conducts only from anode to cathode. For true bidirectional AC switching, two devices must be connected in inverse-parallel configuration, as confirmed in ST's application note AN5012 for soft-start designs.
Is thermal pad soldering required for HU3PAK mounting?
Yes - the HU3PAK package uses the exposed metal slug (cathode-connected) as the primary thermal path. ST's recommended footprint includes a 12.4 × 12.4 mm thermal pad with ≥6 vias to internal ground/copper planes. Omitting this pad increases Rth(j-c) beyond 0.8 °C/W and risks thermal runaway above 20 A RMS.
Does TN3050HP-12L2Y support zero-crossing switching?
It can be used in zero-crossing configurations, but its 1000 V/µs dV/dt immunity and 150 µs turn-off time (tq) require precise gate timing synchronized to voltage zero crossings. Unlike TRIACs, it lacks inherent bidirectional zero-crossing capability and must be paired with external zero-cross detection and phase-delay logic for clean switching.
