Product details
Overview
STPS20200CG-TR from STMicroelectronics is a dual-center-tap 200 V Schottky rectifier in D²PAK package, rated for 2 × 10 A average forward current per diode, 0.64 V typical forward voltage at 125 °C, and 2000 V DC insulation rating. It serves as secondary-side synchronous rectification in high-frequency SMPS and DC–DC converters for LED lighting systems.
For engineers reviewing the STPS20200CG-TR datasheet, STPS20200CG-TR pinout, STPS20200CG-TR application, or STPS20200CG-TR equivalent, key selection criteria include thermal resistance (Rth(j-c) = 1.30 °C/W per diode), reverse leakage (≤7 mA at 125 °C), junction-to-case coupling (0.20 °C/W), insulated package compliance, and D²PAK tape-and-reel availability for automated assembly.
Technical Context
This dual Schottky diode integrates two independent 200 V/10 A rectifiers sharing a common cathode connection (center-tap configuration), enabling efficient full-wave rectification without external wiring. Its low conduction loss stems from ultra-low VF and negligible switching loss due to majority-carrier operation.
The D²PAK package provides enhanced thermal performance over TO-220 variants while maintaining 2000 V DC isolation between case and leads. Junction temperature is managed via conduction cooling, with Rth(j-c) specified per diode and inter-diode thermal coupling quantified at 0.20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in flyback/freewheeling topologies. |
| IF(AV) | 2 × 10 A - Average forward current rating per diode at Tc = 160 °C; supports high-power secondary-side rectification. |
| VF(typ) | 0.64 V @ 10 A, 125 °C - Low conduction loss enables >92% efficiency in 12 V/24 V output SMPS designs. |
| Rth(j-c) | 1.30 °C/W per diode - Enables direct heatsink mounting with predictable thermal rise under continuous load. |
| Insulation | 2000 V DC - Allows safe use in isolated power supplies without additional creepage/clearance barriers. |
| Junction Temp | -40 to +175 °C - Supports operation in industrial ambient environments with minimal derating. |
| Cj | 45 pF - Low junction capacitance minimizes reverse recovery charge and EMI in MHz-range converters. |
Pinout & Package
STPS20200CG-TR uses the surface-mount D²PAK (TO-263) package with three terminals: Cathode (pin 1), Anode 1 (pin 2), and Anode 2 (pin 3). The metal tab is electrically connected to the common cathode and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Common Cathode | Primary thermal interface and electrical return node for both diodes; must be soldered to copper pour for thermal management. |
| Pin 2 | Anode 1 | Input terminal for first diode leg; connects to transformer secondary winding or switch node in center-tap topology. |
| Pin 3 | Anode 2 | Input terminal for second diode leg; completes full-wave rectification path with Pin 2 and shared cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.64 V typ. @ 125 °C enables <1.5 W conduction loss per diode at 10 A, reducing heatsink requirements. |
| Insulated package | 2000 V DC isolation eliminates need for insulating pads in isolated DC–DC designs, simplifying mechanical layout. |
| ECOPACK®2 compliance | Lead-free, RoHS-compliant construction meets global environmental regulations without performance trade-offs. |
| Extremely fast switching | No minority-carrier storage delay ensures zero reverse recovery time, eliminating snubber circuits in high-frequency converters. |
| Low thermal resistance | 1.30 °C/W per diode allows sustained 20 A total device current with ≤30 °C temperature rise above heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH02-M3 | Single 200 V/20 A Schottky; no center-tap; Rth(j-c) = 1.5 °C/W; 1500 V isolation. | Requires two devices and external wiring to replicate center-tap function; higher board area. | Select when discrete layout flexibility is preferred over integrated dual-diode symmetry. |
| ON Semiconductor MBR20200CT | Dual 200 V/10 A in TO-220AB; Rth(j-c) = 0.75 °C/W per device; no isolation; leaded through-hole. | Suitable for prototyping or low-volume through-hole assembly; lacks 2000 V isolation and SMT compatibility. | Select for manual assembly or legacy board designs where D²PAK reflow is unavailable. |

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPS20200CG-TR is rated for continuous operation with case temperature (Tc) up to 160 °C when delivering 2 × 10 A average forward current per diode. At this condition, junction temperature remains within the 175 °C absolute maximum limit assuming proper heatsinking and thermal interface design.
Does the D²PAK package require thermal vias under the tab?
Yes-thermal vias (minimum 6 × 0.3 mm diameter, filled or tented) are required beneath the metal tab to transfer heat from the cathode to internal ground/power planes. Without vias, thermal resistance increases by ≥40%, risking thermal runaway at full rated current.
Can STPS20200CG-TR replace STPS20200CT in existing TO-220AB designs?
No-STPS20200CG-TR uses D²PAK packaging and requires PCB redesign for SMT placement, stencil aperture, and thermal pad layout. While electrically equivalent, mechanical incompatibility prevents drop-in replacement without layout revision and requalification.
What is the recommended torque for mounting screws if used with a heatsink?
The STPS20200CG-TR D²PAK package does not support mechanical screw mounting. Heatsinking must be achieved solely through soldered thermal pad contact. Mechanical clamping or screws are incompatible and risk solder joint fracture or die damage.
