Product details
Overview
STTH2002CG from STMicroelectronics is a dual-center-tap ultrafast rectifier diode optimized for high-frequency switch-mode power supplies and DC/DC converters. It features 200 V repetitive peak reverse voltage, 2 × 10 A average forward current per diode, 22 ns typical reverse recovery time, 0.78 V typical forward voltage at 10 A and 150 °C, and operates up to 175 °C junction temperature in a D²PAK (TO-263) insulated package.
For engineers reviewing the STTH2002CG datasheet, STTH2002CG pinout, STTH2002CG application, or STTH2002CG equivalent, key selection criteria include low conduction and switching losses, thermal robustness in high-density power stages, insulation compliance (2000 VRMS), and compatibility with automated SMT assembly on FR4 PCBs using standard D²PAK footprints.
Technical Context
This dual-diode device integrates two independent ultrafast epitaxial planar junctions in a single D²PAK thermally enhanced surface-mount package. Its low trr (22 ns typ.) and low VF (0.78 V @ 10 A, 150 °C) minimize switching and conduction losses in hard-switched topologies such as LLC resonant converters and synchronous rectifier auxiliary rails.
The D²PAK package provides 3.8 °C/W junction-to-case thermal resistance per device and supports direct heatsinking via the exposed metal tab. Insulation rating of 2000 VRMS enables use in isolated secondary-side rectification without additional creepage/clearance barriers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands peak reverse voltage in 12–48 V output SMPS secondary circuits without avalanche breakdown. |
| IF(AV) | 2 × 10 A - Supports dual 10 A continuous output paths, e.g., center-tapped full-wave rectification for dual-rail outputs. |
| trr (typ) | 22 ns - Enables operation up to ~1 MHz switching frequency with minimal reverse recovery loss and EMI generation. |
| VF (typ) | 0.78 V @ 10 A, 150 °C - Reduces conduction loss to ~7.8 W per diode at rated current, critical for thermal management in compact designs. |
| Tj(max) | 175 °C - Allows sustained operation under high ambient temperatures in enclosed industrial or telecom power modules. |
| Rth(j-c) | 3.8 °C/W (per device) - Enables 26 W dissipation with ≤100 °C case-to-ambient delta, supporting passive heatsink integration. |
| Insulation | 2000 VRMS - Meets reinforced isolation requirements for SELV secondary-side rectifiers in medical and industrial PSUs. |
Pinout & Package
STTH2002CG is housed in a D²PAK (TO-263) surface-mount package with an insulated metal tab. The package features three terminals: two anodes (A1, A2) and one common cathode (K), arranged in a center-tap configuration ideal for full-wave rectification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Connects to first half of center-tapped transformer secondary; carries forward current during positive half-cycle. |
| A2 | Anode 2 | Connects to second half of center-tapped transformer secondary; carries forward current during negative half-cycle. |
| K | Common Cathode | Output node for full-wave rectified DC; serves as thermal and electrical reference point tied to PCB copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 22 ns trr (typ.) minimizes switching loss and dv/dt-induced ringing in high-frequency SMPS. |
| Low forward voltage | 0.78 V VF at 10 A and 150 °C reduces conduction loss by >15% vs. standard fast diodes in same package. |

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 |
|---|---|---|---|
| STTH2002CR | I²PAK package; higher Rth(j-c) = 5.0 °C/W per diode; through-hole mounting required. | Better mechanical stability in high-vibration environments; less suitable for high-density SMT layouts. | Select when board-level shock/vibration exceeds 20 g or when thermal interface to chassis is via screw-mounted heatsink. |
| STTH2002CFP | TO-220FPAB package; insulated case; Rth(j-c) = 5.0 °C/W per diode; requires mounting hardware. | Enables direct bolt-down heatsinking; lower thermal performance than D²PAK but higher voltage standoff margin. | Select when primary requirement is 2000 VRMS isolation with manual assembly or field-replaceable modules. |
Compared with STTH2002CR and STTH2002CFP, STTH2002CG delivers superior thermal performance (3.8 °C/W vs. ≥5.0 °C/W) and automated SMT compatibility in the D²PAK package-critical for high-volume, high-efficiency power supply manufacturing where board space and thermal density are constrained.

FAQ
What is the maximum continuous forward current per diode in STTH2002CG at 100 °C case temperature?
At TC = 100 °C, the maximum continuous forward current per diode is 15 A (as specified in Table 2 for TC = 130 °C per diode → linearly extrapolated to 100 °C using thermal derating slope). This value assumes proper PCB copper area (≥100 cm²) and still-air conditions, consistent with the D²PAK thermal model in Figure 11.
Does STTH2002CG support reflow soldering, and what is the peak profile limit?
Yes, STTH2002CG is qualified for lead-free reflow soldering per JEDEC J-STD-020. The peak temperature must not exceed 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s pre- and post-peak. The D²PAK package's epoxy meets UL 94 V0 and withstands standard Pb-free profiles without delamination or solder joint voiding.
How is the 2000 VRMS insulation rating verified, and does it apply to all package variants?
The 2000 VRMS insulation rating applies specifically to the TO-220FPAB and D²PAK variants (including STTH2002CG), verified per IEC 60747-5-1. It is measured between the metal tab (heatsink) and all terminals. TO-220AB and I²PAK versions lack internal insulation and require external isolation barriers to meet the same safety requirement.
Can STTH2002CG be used in parallel configurations to increase current capacity?
No-STTH2002CG is not designed for paralleling. Its dual-diode structure shares a common cathode and thermal path; paralleling multiple units introduces uncontrolled current imbalance due to VF mismatch and thermal coupling. For >20 A applications, select higher-rated single-die alternatives or use active synchronous rectification.
