Product details
Overview
STTH3002CW from STMicroelectronics is a dual ultrafast recovery rectifier diode in TO-247 package, rated for 200 V repetitive peak reverse voltage and 30 A total average forward current (15 A per diode), with typical forward voltage of 0.75 V at 15 A and 150 °C, and 17 ns typical reverse recovery time - optimized for high-frequency switch-mode power supplies and DC–DC converters.
For engineers reviewing the STTH3002CW datasheet, STTH3002CW pinout, STTH3002CW application, or STTH3002CW equivalent, key selection criteria include thermal resistance (1.5 °C/W per diode, junction-to-case), surge current capability (180 A), insulated mounting compatibility, and low conduction/switching losses in compact high-power topologies.
Technical Context
This dual-center-tab rectifier integrates two independent ultrafast diodes sharing a common cathode configuration (K–A1–A2 pinout), enabling synchronous freewheeling or dual-phase rectification. Its 17 ns trr and low Qrr support operation above 100 kHz without excessive switching loss.
Thermal design relies on case-conducted cooling: Rth(j–c) = 1.5 °C/W per diode (total 1.0 °C/W), with maximum junction temperature of 175 °C and Tc limits of 145 °C for TO-247 packaging - requiring mechanical mounting torque of 0.55 N·m (max 1.0 N·m).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input stages up to 200 V DC or rectified AC bus in industrial SMPS |
| IF(AV) per diode | 15 A - enables 30 A total device output with balanced load sharing across dual die |
| VF (typ) | 0.75 V @ 15 A, 150 °C - reduces conduction loss to ~11.3 W per diode at full rated current |
| trr (typ) | 17 ns - minimizes turn-off energy loss and EMI generation in >100 kHz converters |
| Rth(j–c) per diode | 1.5 °C/W - allows 15 W dissipation per diode before reaching 175 °C junction limit at 145 °C case |
| IFSM | 180 A @ 10 ms - withstands inrush and short-circuit transients in motor drives and UPS systems |
| Tj(max) | 175 °C - supports operation in sealed enclosures or high ambient environments without derating |
Pinout & Package
Packaged in TO-247 (4.46 g, 30 pcs/tube), this dual-diode rectifier uses a center-tab configuration with isolated mounting surface. The metal tab serves as common cathode (K), while pins A1 and A2 are anodes for each diode - enabling independent or paralleled anode routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (center) | Common Cathode (K) | Electrically active heat sink interface; must be electrically isolated if used with floating ground topologies |
| Pin 1 (left) | Anode 1 (A1) | First diode anode; routed separately for phase-split rectification or redundancy |
| Pin 2 (right) | Anode 2 (A2) | Second diode anode; supports interleaved or dual-output converter architectures |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast recovery | 17 ns trr enables efficient operation in 100–500 kHz SMPS without snubbers |
| High surge rating | 180 A non-repetitive peak current supports robust startup and fault handling |
| Low VF at high Tj | 0.75 V @ 150 °C ensures stable efficiency under thermal stress in enclosed designs |
| TO-247 thermal performance | 1.5 °C/W per diode allows >15 W continuous dissipation with standard heatsinking |
| ECOPACK® compliance | Lead-free second-level interconnect meets RoHS and JEDEC JESD97 marking standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual-diode rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR3020CT | 200 V VRRM, 30 A IF(AV), but 35 ns trr and higher VF (0.92 V @ 15 A) | Higher switching loss limits usable frequency to ≤150 kHz; less suitable for high-density SMPS | Select when cost sensitivity outweighs efficiency targets and thermal margin is ample |
| Vishay VS-30CPH02-M3 | 200 V VRRM, 30 A IF(AV), 25 ns trr, but TO-247AC package lacks center-tab isolation | No integrated thermal/electrical isolation between anodes; requires external insulator for floating designs | Select when board space permits discrete mounting and thermal coupling is not required |
Compared with MUR3020CT and VS-30CPH02-M3, STTH3002CW delivers superior high-frequency efficiency via lower trr and VF, plus built-in mounting isolation - making it optimal for thermally constrained, high-reliability SMPS where layout simplicity and thermal predictability are critical.

FAQ
What is the pin configuration of STTH3002CW?
The STTH3002CW uses a three-terminal TO-247 package: the metal tab is the common cathode (K), Pin 1 (left lead) is Anode 1 (A1), and Pin 2 (right lead) is Anode 2 (A2). This center-tab dual-anode layout supports independent or paralleled anode connections while enabling direct thermal coupling to heatsinks.
Can STTH3002CW replace a single 30 A diode in bridge rectifiers?
No - STTH3002CW contains two independent 15 A diodes sharing one cathode, not a single 30 A device. It is designed for dual-path applications like interleaved buck outputs or split-phase rectification. For full-bridge use, two STTH3002CW units or a dedicated 30 A single-diode part would be required.
Is the TO-247 package electrically insulated?
The TO-247 package itself is not inherently insulated; however, STTH3002CW's metal tab (cathode) is electrically active. For isolation, users must apply a dielectric pad or mica washer between tab and heatsink - unlike the TOP3I variant which integrates 2500 Vrms insulation.
What is the recommended mounting torque for STTH3002CW?
The manufacturer specifies 0.55 N·m nominal mounting torque for the TO-247 package, with an absolute maximum of 1.0 N·m. Exceeding this risks cracking the epoxy body or damaging internal wire bonds, compromising thermal performance and long-term reliability under thermal cycling.
