Product details
Overview
STPS20L60CG-TR from STMicroelectronics is a dual-center-tab 60 V, 2 × 10 A low-drop Schottky rectifier in D²PAK package, designed for high-frequency SMPS and DC/DC converters. It delivers typ. 0.48 V forward voltage at 10 A and 125 °C, supports 220 A non-repetitive surge current, and features 1.6 °C/W junction-to-case thermal resistance per diode.
For engineers reviewing the STPS20L60CG-TR datasheet, STPS20L60CG-TR pinout, STPS20L60CG-TR application, or STPS20L60CG-TR equivalent, key selection criteria include forward voltage drop at high temperature, avalanche power rating (430 W), thermal resistance under simultaneous dual-diode conduction, and ECOPACK2 compliance for industrial power supplies.
Technical Context
This dual Schottky rectifier integrates two independent 60 V, 10 A diodes sharing a common cathode tab, enabling synchronous or interleaved operation in center-tapped topologies. Its low dV/dt rating (10,000 V/µs) and negligible reverse recovery charge support stable switching up to several hundred kHz.
The device uses platinum-doped silicon with optimized metal-semiconductor interface to achieve low VF while maintaining 150 °C max junction temperature and specified avalanche capability. Thermal coupling between diodes (Rth(c) = 0.1 °C/W) must be accounted for when both are active simultaneously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per diode; defines usable input voltage range in buck-derived topologies |
| IF(AV) per diode | 10 A at Tc = 135 °C - Continuous DC output current capability per channel with heatsink |
| VF(typ.) | 0.48 V at IF = 10 A, Tj = 125 °C - Directly determines conduction loss: ~4.8 W per diode at rated current |
| Rth(j-c) per diode | 1.6 °C/W - Enables thermal design with case temperature monitoring; total device Rth(j-c) = 0.85 °C/W |
| IFSM | 220 A, tp = 10 ms - Withstands inrush and short-circuit transients without failure |
| PARM | 430 W at tp = 10 µs, Tj = 125 °C - Specifies single-pulse avalanche energy handling during overvoltage events |
Pinout & Package
D²PAK (TO-263) package with exposed copper drain tab for thermal conduction and mechanical mounting. Three terminals: Cathode (common tab), Anode 1, Anode 2 - all electrically isolated except cathode connection shared between diodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Tab) | Common cathode connection for both diodes | Primary thermal path and high-current return node; must be soldered to large copper area or heatsink |
| Anode 1 | Anode of first Schottky diode | Connects to primary-side winding or switching node in center-tapped forward converter |
| Anode 2 | Anode of second Schottky diode | Connects to complementary winding or phase leg in dual-output or interleaved DC/DC designs |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.48 V typ. at 10 A / 125 °C reduces conduction loss by >25% vs. standard silicon rectifiers |
| Negligible switching losses | No reverse recovery charge (Qrr ≈ 0) eliminates turn-off loss and EMI in high-frequency operation |
| Low thermal resistance | 1.6 °C/W per diode enables compact thermal design without forced air cooling in 65–100 W adapters |
| Avalanche capability | 430 W peak avalanche power allows safe clamping of inductive spikes in unregulated flyback or LLC resonant circuits |
| ECOPACK2 compliance | Halogen-free, RoHS-compliant construction meets IEC 61249-2-21 and JEDEC J-STD-020 standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS20L60CT | Same die, TO-220AB package; higher Rth(j-c) = 2.0 °C/W per diode; 0.55 N·m mounting torque required | Better suited for chassis-mounted heatsinks; less compatible with automated SMT assembly | Select when mechanical mounting rigidity or legacy footprint compatibility outweighs SMT process benefits |
| Vishay V20100C-E3/45 | 60 V, 2 × 10 A D²PAK Schottky; VF = 0.62 V typ. at 10 A/125 °C; no specified avalanche rating | Lacks documented PARM rating; requires external clamping for inductive transient protection | Acceptable where cost sensitivity dominates and system-level overvoltage protection is already implemented |
Compared with STPS20L60CT and V20100C-E3/45, STPS20L60CG-TR offers superior thermal performance in SMT layouts, guaranteed avalanche robustness for unclamped topologies, and lower conduction loss-making it optimal for high-density, high-reliability 65–100 W AC/DC adapters.

FAQ
What is the maximum continuous junction temperature for STPS20L60CG-TR?
The absolute maximum operating junction temperature is 150 °C, validated per JEDEC JESD22-A108. Derating is required above Tc = 135 °C for IF(AV); thermal design must ensure junction temperature remains below this limit under worst-case ambient and power dissipation conditions.
Can STPS20L60CG-TR replace a single 20 A Schottky diode?
No-it contains two independent 10 A Schottky diodes with a shared cathode, not a single 20 A device. It is intended for center-tapped or dual-output topologies. Using only one anode forfeits half the die area and degrades thermal balance; parallel use of both anodes is required for full 20 A capability.
Is the D²PAK tab electrically isolated from the anodes?
Yes-the cathode tab is electrically isolated from both anodes. The tab connects exclusively to the common cathode node. Anode 1 and Anode 2 are fully isolated from each other and from the tab, enabling independent circuit connections in transformer center-tapped or interleaved configurations.
Does STPS20L60CG-TR require a minimum solder mask opening under the tab?
Yes-per ST's recommended footprint (DS1595, Fig. 9), a 9.75 mm × 12.20 mm solder mask opening is required under the tab to ensure full copper contact and optimal thermal transfer. Smaller openings increase Rth(j-a) by up to 40% and risk solder voiding during reflow.
