Product details
Overview
STPS10M80CG-TR from STMicroelectronics is a dual common-cathode Schottky rectifier in D2PAK package, rated for 80 V repetitive peak reverse voltage and 2 × 5 A average forward current per diode at Tc = 160 °C, with typical forward voltage drop of 0.550 V at 5 A and 125 °C. It delivers low conduction loss and high thermal robustness in high-frequency SMPS for notebook adapters and LCD TV power supplies.
For engineers reviewing the STPS10M80CG-TR datasheet, STPS10M80CG-TR pinout, STPS10M80CG-TR application, or STPS10M80CG-TR equivalent, key selection factors include its 175 °C max junction temperature, 45 pF package capacitance (in TO-220FPAB variant), avalanche-rated 100 V peak voltage, and insulated thermal performance in D2PAK mounting configuration.
Technical Context
This dual Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling synchronous rectification or dual-output DC/DC conversion. Its low VF–IR trade-off is optimized for efficiency across light-to-heavy loads in 100–500 kHz switching converters.
Thermal design relies on junction-to-case resistance of 3.10 °C/W per diode (D2PAK), with coupling resistance of 0.65 °C/W between diodes. Avalanche capability is validated to 4000 W peak power (tp = 1 µs) and 100 V repetitive peak voltage under controlled IAR < 12 A conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - maximum reverse blocking voltage before breakdown; sets upper limit for input/output rail separation in buck-derived topologies |
| IF(AV) per diode | 5 A at Tc = 160 °C - defines continuous DC output current capability per channel when mounted on heatsink |
| VF (typ) | 0.550 V at 5 A, 125 °C - directly determines conduction loss: ~2.75 W per diode at full load |
| Tj (max) | 175 °C - enables operation in thermally constrained enclosures without derating below 150 °C ambient |
| Rth(j-c) per diode | 3.10 °C/W - quantifies thermal bottleneck from silicon junction to case surface; critical for heatsink sizing |
| IR (max) | 15 mA at 125 °C, VR = 80 V - leakage contributes to standby power loss; impacts no-load efficiency in adapter designs |
Pinout & Package
STPS10M80CG-TR uses the D2PAK (TO-263) surface-mount package with three terminals: two anodes (A1, A2) and one common cathode (K). The exposed metal tab is electrically connected to the cathode and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | Input node for first rectification path; connects to transformer secondary or switch node in synchronous rectifier |
| A2 | Anode 2 | Independent input node for second rectification path; supports dual-output or interleaved converter architectures |
| K | Common Cathode | Shared output node tied to system ground or output capacitor; tab must be soldered to copper pour for thermal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Optimized VF–IR trade-off | 0.550 V VF at 5 A / 125 °C and only 15 mA IR at same condition - balances efficiency and leakage in wide-load-range adapters |
| Avalanche-rated structure | 100 V VARM, 4000 W PARM (tp = 1 µs) - withstands transient overvoltage during MOSFET turn-off without external clamping |
| High-temperature operation | 175 °C Tj(max) - eliminates need for oversized heatsinks in compact, sealed power supplies |
| Dual-diode integration | Common-cathode topology in single D2PAK - reduces PCB area vs. discrete diodes and improves layout symmetry for EMI control |
Applications
| Notebook AC-DC Adapter | LCD TV Standby Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MBR1080CT | Same 80 V VRRM, 10 A total IF(AV), but TO-220AB package; Rth(j-c) = 3.5 °C/W per diode vs. 3.10 °C/W | Requires through-hole assembly and larger heatsink; lacks avalanche rating | Preferred where legacy through-hole manufacturing exists and avalanche immunity is not required |
| Vishay VS-10BQ080PBF | Single-diode D2PAK, 80 V, 10 A IF(AV); no dual-anode topology; VF = 0.57 V @ 5 A, 125 °C | Cannot support dual-output or interleaved configurations without adding second device | Select when only one rectification path is needed and board space allows separate cathode routing |
Compared with MBR1080CT and VS-10BQ080PBF, STPS10M80CG-TR uniquely combines dual-anode integration, avalanche robustness, and superior thermal resistance in surface-mount D2PAK-enabling higher power density and transient resilience in compact SMPS designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The STPS10M80CG-TR supports continuous operation up to 160 °C case temperature (Tc) per diode, as specified in Table 2. Exceeding this requires derating per Figure 3; sustained Tc > 160 °C risks accelerated parametric drift and reduced lifetime.
Is the cathode tab electrically isolated from the PCB ground plane?
No-the cathode (K) terminal and the exposed metal tab are internally connected and must be routed to the system's common cathode net. Electrical isolation is not provided; thermal interface material must be non-conductive if mounting to grounded heatsinks.
Does this part meet JEDEC moisture sensitivity level (MSL) requirements for reflow?
Yes-STPS10M80CG-TR is qualified per JEDEC J-STD-020 at MSL 1, meaning it has unlimited floor life and may be subjected to standard Pb-free reflow profiles (peak 260 °C) without baking preconditioning.
Can both anodes be driven with different switching waveforms simultaneously?
Yes-A1 and A2 are fully independent anodes sharing only the cathode node. They support asynchronous or phase-shifted drive schemes, such as in dual-output flyback or interleaved forward converters, with no internal coupling.
