Product details
Overview
STTH1002CG-TR from STMicroelectronics is a dual-center-tap ultrafast rectifier diode in D²PAK (TO-263) package, rated for 200 V repetitive peak reverse voltage and 8 A average forward current per diode at Tc = 135 °C. It delivers low conduction loss (VF typ. 0.78 V @ 5 A, 150 °C), 20 ns typical reverse recovery time, and operates up to 175 °C junction temperature - optimized for high-frequency switch-mode power supplies and DC-DC converters.
For engineers reviewing the STTH1002CG-TR datasheet, STTH1002CG-TR pinout, STTH1002CG-TR application, or STTH1002CG-TR equivalent, this device is selected for low-loss freewheeling, polarity protection, and low-voltage high-frequency inverter designs where thermal robustness and fast switching are critical.
Technical Context
This dual-diode center-tapped rectifier integrates two independent ultrafast switching diodes sharing a common cathode connection. Its design targets high-efficiency SMPS topologies requiring simultaneous low VF and low trr to minimize switching and conduction losses.
Thermal performance is defined by Rth(j-c) = 4.0 °C/W per diode (D²PAK), enabling stable operation at 175 °C junction temperature. The device supports surge currents up to 50 A (10 ms sine) and exhibits low leakage (<5 µA @ 25 °C, <40 µA @ 125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands repetitive reverse voltages up to 200 V without breakdown in SMPS flyback or forward converter secondary-side applications. |
| IF(AV) per diode | 8 A @ Tc = 135 °C - Sustains continuous 8 A DC forward current per diode with heatsink mounting, supporting high-power density rectification. |
| VF (typ) | 0.78 V @ 5 A, 150 °C - Low forward drop reduces conduction loss and improves efficiency in low-voltage output stages (e.g., 3.3 V/5 V rails). |
| trr (typ) | 20 ns @ IF = 1 A, VR = 30 V, dIF/dt = 100 A/µs - Enables clean commutation in >100 kHz DC-DC converters, minimizing switching noise and EMI. |
| Tj (max) | 175 °C - Allows operation in thermally constrained environments such as enclosed industrial PSUs or automotive under-hood power modules. |
| Rth(j-c) per diode | 4.0 °C/W - Specifies thermal resistance from junction to case in D²PAK, enabling accurate heatsink sizing for thermal management. |
| IR (max) | 40 µA @ 125 °C, VR = VRRM - Low leakage preserves efficiency in standby modes and high-temperature operation. |
Pinout & Package
STTH1002CG-TR uses the D²PAK (TO-263) surface-mount package with three terminals: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). The exposed metal tab (Pin 2) serves as the common cathode and primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input anode of Diode 1 | Connects to transformer secondary winding or input rail for first half-cycle rectification in center-tap topology. |
| Pin 2 (Cathode) | Common cathode node | Shared output terminal for both diodes; electrically and thermally connected to exposed metal tab for low-inductance, high-current return path. |
| Pin 3 (Anode 2) | Input anode of Diode 2 | Connects to opposite phase of center-tapped winding or second input rail, enabling full-wave rectification without center-tap transformer bias. |
Key Features
| Feature | Design Value |
|---|---|
| Dual center-tap configuration | Enables single-package full-wave rectification in offline SMPS and isolated DC-DC converters, reducing board space vs. discrete diode pairs. |
| Ultrafast recovery (20 ns typ.) | Minimizes reverse recovery charge (Qrr) and associated switching loss, critical for >100 kHz operation in LLC and phase-shifted full-bridge topologies. |
| Low VF (0.78 V typ. @ 150 °C) | Reduces conduction loss by ~15% compared to standard FRDs at same current, directly improving system efficiency in 12 V and lower output rails. |
| 175 °C maximum junction temperature | Supports reliable operation in high-ambient environments (e.g., industrial motor drives, telecom rectifiers) without derating at full load. |
| ECOPACK®2 compliance | Meets RoHS and halogen-free requirements for environmentally regulated markets including EU and China RoHS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-center-tap rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1002CT | TO-220AB through-hole package; identical electrical specs but higher Rth(j-c) = 4.0 °C/W per device (not per diode), no insulation. | Suitable for prototyping or low-volume industrial PSUs where manual assembly and larger heatsinks are acceptable. | Select when mechanical robustness and serviceability outweigh surface-mount density and thermal efficiency. |
| STTH1002CR | I²PAK package; same VRRM/IF ratings but Rth(j-c) = 4.0 °C/W per diode, slightly larger footprint than D²PAK. | Preferred in high-reliability avionics or military DC-DC where leaded packages meet vibration/shock standards. | Choose when IPC Class 3 solder joint reliability and legacy footprint compatibility are mandatory. |
Compared with STTH1002CT and STTH1002CR, STTH1002CG-TR offers superior thermal performance per unit area (D²PAK's 4.0 °C/W per diode with compact footprint), making it optimal for high-power-density, automated SMT production in telecom and server applications.

FAQ
What is the maximum average forward current per diode for STTH1002CG-TR at 135 °C case temperature?
The maximum average forward current per diode is 8 A at Tc = 135 °C, as specified in Table 2 of the official ST datasheet (DocID10182 Rev 8). This rating assumes proper PCB copper area for thermal conduction and accounts for shared thermal path between diodes in the D²PAK package.
Does STTH1002CG-TR have insulated packaging like the TO-220FPAB variant?
No. STTH1002CG-TR uses the D²PAK (TO-263) package, which lacks internal insulation. Unlike the TO-220FPAB version (2000 VRMS isolation), this part requires external insulation (e.g., insulating pad or coated heatsink) when mounted to conductive surfaces in high-voltage systems.
Can STTH1002CG-TR be used in place of a single ultrafast diode in non-center-tap circuits?
Yes, but only one anode (Pin 1 or Pin 3) should be used with the common cathode (Pin 2); the unused anode must be left unconnected or tied to a fixed potential below cathode voltage. Using both anodes simultaneously without center-tap configuration risks reverse bias failure due to internal coupling.
What is the recommended PCB footprint for thermal performance in STTH1002CG-TR?
Per ST's layout guidelines, a minimum 200 mm² copper pour (20 mm × 10 mm) connected to Pin 2 (cathode tab) with ≥4 thermal vias (0.3 mm diameter, filled) is required to achieve the specified 4.0 °C/W Rth(j-c). Smaller pads increase junction temperature by up to 45 °C at full load.
