Product details
Overview
STTH10LCD06SG-TR from STMicroelectronics is an ultrafast high-voltage silicon rectifier diode in DPAK (TO-252) package, rated for 600 V repetitive peak reverse voltage, 10 A average forward current, and 35 ns typical reverse recovery time. It employs ST's Turbo 2 technology to minimize conduction and switching losses, and is specifically engineered for power supply stages in LCD flat panel displays.
For engineers reviewing the STTH10LCD06SG-TR datasheet, STTH10LCD06SG-TR pinout, STTH10LCD06SG-TR application, or STTH10LCD06SG-TR equivalent, key selection criteria include its low thermal resistance (3.5 °C/W), 1.3 V typical forward voltage at 150 °C, 13 µA reverse leakage at 150 °C, insulated package compliance, and suitability for high-frequency SMPS in display backlight and main power rails.
Technical Context
This device operates as a unidirectional power rectifier with optimized minority-carrier lifetime control for fast soft recovery. Its Turbo 2 process delivers balanced trade-offs between forward voltage drop (VF), reverse recovery time (trr), and reverse recovery charge (Qrr), enabling efficient operation at switching frequencies up to several hundred kHz.
The DPAK package provides enhanced thermal performance over standard SMD packages, with direct thermal path from junction to PCB copper via exposed cathode pad. The device is rated for maximum junction temperature of 175 °C and supports surge currents up to 100 A (10 ms sine half-wave), making it suitable for transient-heavy display power architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands repetitive reverse voltage up to 600 V, enabling use in 400 V DC bus applications with safety margin. |
| IF(AV) | 10 A - Sustains 10 A average forward current at Tc = 105 °C, supporting continuous operation in compact display power supplies. |
| trr (typ) | 35 ns - Ultrafast recovery minimizes switching loss and EMI in high-frequency flyback and LLC converters. |
| VF (typ) | 1.3 V at 150 °C - Low forward drop reduces conduction loss and thermal stress under full-load conditions. |
| Rth(j-c) | 3.5 °C/W - Enables effective heat transfer to PCB copper, allowing thermal design without external heatsink in many display applications. |
| IR (max) | 130 µA at 150 °C - Low leakage preserves efficiency and stability in high-temperature display enclosures. |
| IFS M | 100 A - Handles short-duration inrush and fault currents common during LCD power-up and lamp ignition. |
Pinout & Package
DPAK (TO-252) package with three terminals: Cathode (large exposed pad), Anode (pin 1), and Gate not applicable (rectifier diode). Thermal pad is electrically connected to cathode and must be soldered to PCB copper for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to input side of rectification stage (e.g., transformer secondary or bridge output). |
| Cathode (Exposed Pad) | Forward current exit / thermal interface | Electrically tied to output rail and serves as primary thermal conduction path to PCB ground plane. |
| Pin 2 (NC) | No connection | Not internally bonded; left floating per datasheet - no routing or soldering required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | 35 ns trr with low IRM (2.0–2.8 A) reduces voltage overshoot and snubber losses in hard-switched topologies. |
| Turbo 2 silicon technology | Optimized carrier lifetime control enables simultaneous low VF (1.3 V) and low Qrr (<100 nC), improving overall efficiency. |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements without compromising thermal or electrical performance. |
| Low Rth(j-c) | 3.5 °C/W allows >8 W dissipation on 2 oz Cu with 25 cm² thermal pad - eliminates need for discrete heatsinks in space-constrained displays. |
| High Tj(max) | 175 °C rating supports reliable operation in sealed display enclosures with ambient temperatures up to 85 °C. |
Applications
| LCD TV Main Power Supply | LED Backlight Driver Rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10LCD06S | Same die, identical electrical specs, but marked 'TH10LCD06S' and shipped in tape-and-reel (2500 pcs); no functional difference. | No application difference - fully interchangeable in layout and thermal design. | Select when automated pick-and-place assembly is required and volume exceeds 2500 units. |
| ON Semiconductor MUR1060CT | Higher VF (1.7 V typ at 150 °C), slower trr (60 ns typ), higher Rth(j-c) (4.5 °C/W), dual-die TO-220AB package. | Requires larger heatsink and yields ~3% lower efficiency in high-frequency designs; suited for lower-cost, lower-density boards. | Choose only if legacy TO-220 footprint compatibility is mandatory and efficiency targets permit 0.4 V higher VF penalty. |
Compared with STTH10LCD06SG-TR, STTH10LCD06S offers identical performance in tape-and-reel packaging, while MUR1060CT trades efficiency and thermal performance for TO-220 mechanical compatibility - making the ST part optimal for modern DPAK-based, high-efficiency display power designs.

FAQ
What is the thermal pad connection requirement for STTH10LCD06SG-TR?
The exposed cathode pad must be soldered to a minimum 25 mm² copper area on the PCB using at least 4 thermal vias (0.3 mm diameter, spaced ≤2 mm apart) to achieve the specified 3.5 °C/W junction-to-case thermal resistance. Leaving the pad unconnected raises Rth(j-c) to >12 °C/W and risks thermal runaway at full load.
Does STTH10LCD06SG-TR support synchronous rectification?
No - STTH10LCD06SG-TR is a passive silicon PN junction rectifier diode with no gate terminal or control interface. It cannot be actively driven like a MOSFET; synchronous rectification requires externally controlled FETs and a dedicated driver circuit.
Can this diode replace a standard 600 V FRD in an existing design?
Yes, provided the PCB footprint matches DPAK (TO-252) and thermal pad layout is implemented. Electrical replacement is direct: same VRRM, IF(AV), and IFSM ratings. However, its faster trr may increase ringing in poorly damped layouts - verify snubber values and layout parasitics before drop-in substitution.
What is the meaning of 'SG' suffix in STTH10LCD06SG-TR?
The 'SG' denotes ST's standard green (halogen-free, RoHS-compliant) version per ECOPACK®2 specification. It confirms the device uses lead-free terminations and halogen-free molding compound, with full qualification per JEDEC J-STD-020 and JESD22-A108.
