Product details
Overview
STTH2002CR from STMicroelectronics is a dual-center-tap ultrafast recovery rectifier diode in I²PAK package, rated for 200 V repetitive peak reverse voltage, 2 × 10 A average forward current per diode, and 22 ns typical reverse recovery time. It operates up to 175 °C junction temperature and delivers low conduction losses (VF = 0.78 V typ. at 10 A, 150 °C) for high-efficiency switch-mode power supplies.
For engineers reviewing the STTH2002CR datasheet, STTH2002CR pinout, STTH2002CR application, or STTH2002CR equivalent, key selection criteria include reverse recovery performance under high dIF/dt conditions, thermal resistance (Rth(j-c) = 2.5 °C/W per diode), insulated mounting compatibility, and dual-diode center-tap configuration for bridgeless or synchronous rectification topologies.
Technical Context
This dual-diode rectifier integrates two independent ultrafast switching diodes in a single I²PAK thermally optimized package with isolated metal tab. Its low trr (22 ns typ.) and low VF enable high-frequency operation (>100 kHz) in DC/DC converters while minimizing switching and conduction losses.
The device supports simultaneous conduction of both diodes with coupled thermal behavior-junction-to-case resistance per diode is 2.5 °C/W, and coupling resistance between diodes is 0.7 °C/W-enabling accurate thermal modeling for continuous dual-diode operation in free-wheeling and polarity protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage per diode; enables use in 12–48 V output SMPS with safety margin |
| IF(AV) per diode | 10 A - Continuous average forward current rating per diode at TC = 150 °C; defines steady-state power handling |
| trr (typ) | 22 ns - Typical reverse recovery time at IF = 1 A, VR = 30 V, dIF/dt = 100 A/µs; critical for EMI reduction in high-frequency converters |
| VF (typ) | 0.78 V at 10 A, 150 °C - Low forward voltage drop ensures <1.25 W conduction loss per diode at rated current |
| Tj (max) | 175 °C - Maximum junction temperature; allows operation in compact, high-power-density industrial power supplies |
| Rth(j-c) per diode | 2.5 °C/W - Junction-to-case thermal resistance; determines heatsink sizing when mounted to PCB copper or external heatsink |
Pinout & Package
STTH2002CR uses the I²PAK (TO-262) package with isolated metal slug, requiring through-hole mounting. The package features three terminals: two anodes (A1, A2) and one shared cathode (K), arranged in center-tap dual-diode topology.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input terminal for first half of dual-diode path; connects to primary-side switching node in center-tap rectifier |
| A2 | Anode of Diode 2 | Input terminal for second half; enables complementary conduction in push-pull or full-wave configurations |
| K | Common Cathode | Output node for both diodes; serves as positive DC output rail in center-tap transformer-based SMPS |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr = 22 ns typ. minimizes reverse recovery charge (Qrr) and associated switching losses in >100 kHz converters |
| High-temperature operation | 175 °C max Tj enables reliable performance in sealed enclosures or high-ambient industrial environments |
| Low leakage current | IR ≤ 100 µA at 125 °C, VRRM ensures stable blocking in high-temperature standby modes |
| Insulated package | I²PAK metal slug provides 2000 VRMS isolation; eliminates need for insulating washers in heatsink mounting |
Applications
| Server PSU Rectification | Industrial DC/DC Converter |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002CT | Same die, TO-220AB package; Rth(j-c) = 2.5 °C/W per diode but no insulation; requires insulating hardware | Preferred where mechanical mounting constraints favor TO-220 footprint and heatsink isolation is managed externally | Select when cost-sensitive designs allow added assembly steps for insulator washers and shoulder screws |
| STTH2002CG | Same die, D²PAK package; Rth(j-c) = 2.5 °C/W per diode; surface-mount compatible but higher profile than I²PAK | Suitable for automated SMT lines; less suitable for high-vibration environments due to solder joint stress | Choose for volume production with pick-and-place capability and adequate board-level thermal relief |
Compared with STTH2002CT and STTH2002CG, STTH2002CR offers identical electrical performance in a through-hole I²PAK package that balances thermal efficiency, mounting robustness, and insulation-making it optimal for industrial power modules where reliability under thermal cycling and mechanical shock is critical.

FAQ
What is the maximum allowable case temperature for continuous operation of STTH2002CR?
The maximum case temperature depends on operating mode: for per-diode conduction at 10 A, TC must not exceed 150 °C; for full-device conduction (20 A total), TC must be limited to 130 °C per the absolute ratings table. Exceeding these limits risks thermal runaway due to the (dPtot/dTj) < (1/Rth(j-a)) condition.
Can STTH2002CR be used in parallel with another identical device to increase current capacity?
No-STTH2002CR is not characterized or recommended for paralleling. Its VF vs. temperature coefficient is not matched across units, leading to current imbalance. For higher current, select a single higher-rated device such as STTH30L06D (30 A, 60 V) or redesign with interleaved phases.
Is the I²PAK metal slug electrically isolated from all internal terminals?
Yes-the I²PAK package provides 2000 VRMS isolation between the metal slug (heatsink interface) and all internal terminals (A1, A2, K). This eliminates the need for insulating pads or shoulder screws when mounting to grounded heatsinks, reducing thermal resistance and assembly complexity.
Does STTH2002CR support reflow soldering?
No-STTH2002CR in I²PAK package requires through-hole mounting only. Reflow or wave soldering is prohibited per ST's datasheet: "Mounting (soldering) the I2PAK metal slug with alloy, like a surface mount device, IS NOT PERMITTED." Hand-soldering or selective wave is acceptable with controlled thermal profiles.
