Product details
Overview
STTH3002CPI from STMicroelectronics is an insulated ultrafast dual center-tab rectifier diode in TOP3I package, rated for 200 V repetitive peak reverse voltage, 30 A total average forward current (15 A per diode), and 175 °C maximum junction temperature. It delivers low conduction loss (VF = 0.75 V typ. at 15 A, 150 °C) and fast switching (trr = 17 ns typ. at 25 °C), optimized for high-frequency DC–DC converters and SMPS secondary-side rectification.
For engineers reviewing the STTH3002CPI datasheet, STTH3002CPI pinout, STTH3002CPI application, or STTH3002CPI equivalent, key selection criteria include its 2500 Vrms insulation rating, 12 pF junction capacitance, thermal resistance (Rth(j-c) = 2.3 °C/W total), surge capability (180 A IFSM), and suitability for polarity protection and freewheeling in industrial power supplies.
Technical Context
This dual-diode rectifier integrates two independent ultrafast silicon PN junctions in a single insulated TO-style package. Its design targets high-efficiency, high-frequency operation with minimal reverse recovery charge (Qrr ≈ 25 nC typ. at dIF/dt = 200 A/µs) and low forward voltage drop across wide temperature range (–65 to +175 °C).
The TOP3I variant features reinforced electrical isolation (2500 Vrms), 3.5 °C/W per-diode junction-to-case thermal resistance, and mechanical mounting optimized for heatsink conduction cooling. Its dynamic performance-particularly trr < 22 ns max and IRM ≤ 7.8 A-is specified under realistic conditions: IF = 15 A, VR = 160 V, Tj = 125 °C, dIF/dt = 200 A/µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands up to 200 V repetitive reverse voltage without breakdown, enabling use in 12–48 V output SMPS with margin. |
| IF(AV) per diode | 15 A at Tc = 125 °C - Sustains continuous 15 A DC current per diode with case temperature held at 125 °C. |
| trr (typ) | 17 ns - Enables switching frequencies >500 kHz with minimal switching loss and EMI generation. |
| VF (typ) | 0.75 V at 15 A, 150 °C - Reduces conduction loss to ~11.3 W per diode at full load, improving system efficiency. |
| IFS M | 180 A - Handles short-duration inrush or fault currents (10 ms sinusoidal), supporting robust overcurrent protection. |
| Rth(j-c) total | 2.3 °C/W - Limits junction-to-case temperature rise to 52.9 °C at 23 W dissipation, critical for thermal design in enclosed power modules. |
| Isolation voltage | 2500 Vrms - Provides reinforced insulation between die and mounting tab, meeting IEC/UL creepage/clearance requirements for Class II systems. |
Pinout & Package
Packaged in TOP3I (insulated TO-220 variant), STTH3002CPI uses a 3-terminal configuration with electrically isolated metal tab. The package provides 2500 Vrms isolation between semiconductor die and mounting surface, 12 pF inter-terminal capacitance, and torque specification of 0.9–1.2 N·m for secure heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input terminal for first diode; connects to high-side switching node in synchronous rectifier or freewheeling path. |
| K | Cathode (common) | Shared cathode node for both diodes; serves as output/return rail in dual-output or center-tap configurations. |
| A2 | Anode 2 | Input terminal for second diode; enables dual-channel rectification or independent freewheeling paths. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | trr = 17 ns typ. minimizes switching loss and ringing in high-frequency converters (>300 kHz). |
| High surge current | 180 A IFSM supports reliable operation during startup, overload, or transient events without degradation. |
| Insulated mounting | 2500 Vrms isolation eliminates need for insulating washers in floating-ground topologies like LLC resonant converters. |
| Low VF at high Tj | 0.84 V max at 15 A, 150 °C ensures stable conduction loss across industrial temperature range. |
| Thermal robustness | Tj(max) = 175 °C allows sustained operation in compact, thermally constrained enclosures without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30L06CW | 600 V VRRM, same TOP3I package, but VF = 1.7 V typ. at 15 A - higher conduction loss. | Designed for 380 V PFC front-end, not optimized for low-VF secondary-side rectification. | Select only when higher reverse voltage rating is mandatory; expect ~1.2 W extra loss per diode at 15 A. |
| IXYS MUR3020CT | TO-220AB package (non-insulated), 200 V VRRM, trr = 35 ns - slower recovery, no isolation. | Requires insulating hardware for mounting; unsuitable for floating-ground or Class II designs. | Use only in cost-sensitive, non-isolated applications where 2500 Vrms isolation is not required. |
Compared with STTH3002CPI, STTH30L06CW trades lower VF for higher VRRM-increasing conduction loss by 1.3×-while MUR3020CT lacks insulation and doubles trr, raising EMI risk and limiting usable frequency to <200 kHz.

FAQ
What is the maximum recommended mounting torque for STTH3002CPI?
The manufacturer specifies a torque range of 0.9–1.2 N·m for the TOP3I package mounting screw. Exceeding 1.2 N·m risks damaging the internal die attach or compromising the 2500 Vrms insulation barrier. Use a calibrated torque screwdriver and verify flatness of heatsink surface to ensure uniform pressure distribution across the insulated tab.
Can STTH3002CPI be used in parallel with another unit for higher current handling?
No-STTH3002CPI is not characterized for parallel operation. Its VF vs. temperature curve shows positive TC, but mismatched thermal coupling between devices leads to current imbalance. For >30 A applications, select a single higher-rated part (e.g., STTH6002CW) or redesign using interleaved phases rather than paralleling discrete packages.
Does STTH3002CPI meet RoHS and REACH compliance?
Yes-STTH3002CPI is manufactured in ST's ECOPACK®-compliant process, featuring lead-free second-level interconnects and full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The inner box label and device marking confirm "RoHS6" and "Pb-free" status per JEDEC JESD97.
What is the typical junction capacitance and how does it affect EMI?
STTH3002CPI exhibits 12 pF typical junction capacitance at VR = 30 V, measured at 1 MHz. This low Cj minimizes displacement current during hard-switching transitions, reducing common-mode EMI in high-dv/dt environments. At 200 kHz switching, capacitive current remains below 1 mA, avoiding gate-drive interference in adjacent MOSFETs.
