Product details
Overview
STTH3002CG from STMicroelectronics is a dual-center-tab ultrafast recovery rectifier diode in D2PAK package, rated for 200 V repetitive peak reverse voltage, 30 A total average forward current (15 A per diode), and 17 ns typical reverse recovery time at 25 °C. It delivers low conduction losses (VF typ. 0.75 V at 15 A, 150 °C) and high surge capability (180 A IFSM), targeting high-frequency DC–DC converters and SMPS secondary-side rectification.
For engineers reviewing the STTH3002CG datasheet, STTH3002CG pinout, STTH3002CG application, or STTH3002CG equivalent, key selection criteria include thermal resistance (Rth(j–c) = 1.0 °C/W total), insulated packaging suitability for reinforced isolation, dual-diode configuration for synchronous or interleaved topologies, and ECOPACK® lead-free compliance for industrial power supply design.
Technical Context
This dual-diode rectifier operates with independent junctions sharing a common cathode (K) and isolated anodes (A1, A2), enabling parallel or half-bridge freewheeling configurations. Its ultrafast trr (17–22 ns) and low Qrr support switching frequencies up to several hundred kHz without excessive switching loss.
Thermal performance is defined per diode (Rth(j–c) = 1.5 °C/W) and as a total device (1.0 °C/W), requiring direct heatsink mounting via the exposed copper tab. The D2PAK package provides 1.48 g mass, 8.95–9.35 mm body width (D), and 15.00–15.85 mm length (L), with FR4 PCB copper area recommendations for Rth(j–a) optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum reverse blocking voltage per diode; defines safe operating range in flyback or LLC resonant converter secondary side. |
| IF(AV) per diode | 15 A - Continuous DC current rating per diode at Tc = 150 °C; supports 30 A total output in dual-path designs. |
| trr (typ) | 17 ns - Measured at IF = 1 A, dIF/dt = 200 A/µs, VR = 30 V, Tj = 25 °C; enables <500 kHz hard-switched operation with minimal turn-off loss. |
| VF (typ) | 0.75 V - Forward voltage at IF = 15 A, Tj = 150 °C; reduces conduction loss to ~11.3 W per diode at full load. |
| Rth(j–c) total | 1.0 °C/W - Junction-to-case thermal resistance for both diodes combined; requires ≤30 W total dissipation for ΔTj ≤ 30 °C rise above heatsink. |
| IFS M | 180 A - Non-repetitive surge current (tp = 10 ms, sinusoidal); withstands inrush and short-circuit transients in 48 V telecom PSUs. |
Pinout & Package
STTH3002CG uses a surface-mount D2PAK (TO-263) package with three terminals: two anodes (A1, A2) and one shared cathode (K), mounted on a single exposed copper tab for thermal and electrical connection. The package complies with ECOPACK® lead-free interconnect standards and UL94 V0 epoxy molding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode path; electrically isolated from A2; used in dual-output or phase-interleaved rectification. |
| A2 | Anode 2 | Input terminal for second diode path; independent of A1; allows separate control or sensing in synchronous rectifier gate drive circuits. |
| K | Common Cathode | Shared output node for both diodes; connects directly to output rail or ground return; serves as primary thermal interface to PCB heatsink pad. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr = 17 ns typ. enables high-frequency operation (>300 kHz) with reduced EMI and switching loss vs. standard fast recovery diodes. |
| Dual-diode integration | Two independent 15 A diodes in one D2PAK footprint reduce board area by ~40% versus discrete TO-220 solutions in dual-rail supplies. |
| Low VF at high Tj | VF = 0.75 V @ 15 A, 150 °C ensures stable efficiency across industrial temperature range without derating penalties. |
| High surge robustness | 180 A IFSM rating supports 2× overcurrent tolerance during startup or fault conditions in 1 kW server PSUs. |

FAQ
What is the maximum recommended case temperature for continuous operation?
The STTH3002CG is rated for IF(AV) = 30 A total at Tc = 145 °C for TO-220AB/TO-247/I2PAK/D2PAK packages. For D2PAK specifically, sustained case temperatures must not exceed 145 °C to maintain 30 A average current capability; exceeding this requires linear derating per Figure 1 in the datasheet.
Can STTH3002CG be used in place of STTH3002CT in a TO-220AB footprint?
No - STTH3002CG uses a D2PAK (TO-263) package with different pad layout, thermal pad geometry, and mounting torque requirements. It is not mechanically or thermally interchangeable with the TO-220AB-packaged STTH3002CT without PCB redesign and thermal validation.
Does the D2PAK variant provide galvanic isolation between anodes?
Yes - A1 and A2 are electrically isolated from each other (no internal connection), with isolation rated by package construction, not specified as a safety parameter. For reinforced isolation, external creepage/clearance and PCB layout must comply with IEC 62368-1; the device itself is not certified for safety isolation.
How does the dual-diode configuration affect thermal management?
Both diodes share a common cathode tab and thermal path to the heatsink, resulting in a total Rth(j–c) of 1.0 °C/W. This allows coordinated thermal design but requires careful layout to avoid localized hot spots; simultaneous full-load operation of both diodes demands ≥30 W total heatsink capacity to limit ΔTj to 30 °C.
