Product details
Overview
STPS10SM80CFP from STMicroelectronics is a 10 A, 80 V Schottky rectifier diode in a compact PowerFLAT™ 5x6 package with low forward voltage (VF = 0.79 V at 10 A) and high surge current capability (IFSM = 120 A). It serves as an output rectifier in high-efficiency AC-DC and DC-DC power supplies for telecom and industrial SMPS.
For engineers reviewing the STPS10SM80CFP datasheet, STPS10SM80CFP pinout, STPS10SM80CFP application, or STPS10SM80CFP equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (RthJ-A = 40 °C/W), junction temperature rating (Tj = 175 °C), and low reverse recovery charge (Qrr < 50 nC) for reduced switching losses in high-frequency converters.
Technical Context
This Schottky diode uses platinum-silicide (PtSi) barrier technology to achieve ultra-low VF while maintaining stable leakage performance up to 175 °C. Its planar structure and copper clip bonding minimize parasitic inductance and enhance thermal dissipation through the exposed drain pad.
The device operates without minority-carrier storage, eliminating reverse recovery time (trr ≈ 0 ns), making it suitable for synchronous rectification replacement and high-frequency (>100 kHz) flyback and LLC resonant topologies where fast switching and low conduction loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Repetitive Reverse Voltage (VRRM) | 80 V - Supports 48 V input bus designs with 2× safety margin against transient spikes. |
| Continuous Forward Current (IF(AV)) | 10 A @ TC = 110 °C - Enables compact heatsink-free operation in PCB-mounted 50–100 W power stages. |
| Forward Voltage Drop (VF) | 0.79 V @ IF = 10 A, TJ = 125 °C - Reduces conduction loss by ~35% vs. comparable Si PN diodes. |
| Junction-to-Ambient Thermal Resistance (RthJ-A) | 40 °C/W - Achieved via PowerFLAT™ 5x6 exposed thermal pad; enables direct copper pour mounting. |
| Peak Forward Surge Current (IFSM) | 120 A @ tP = 10 ms - Withstands repetitive line-start surges in offline adapters without derating. |
| Reverse Recovery Charge (Qrr) | < 50 nC - Near-zero stored charge eliminates switching tail current, reducing EMI and MOSFET stress. |
Pinout & Package
Package: PowerFLAT™ 5x6 (3.3 mm height), surface-mount, thermally enhanced with exposed cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Input terminal for forward conduction | Connected to switching node (e.g., transformer secondary or high-side switch drain); requires low-inductance layout. |
| Cathode (K) | Output terminal for forward conduction | Exposed metal pad on bottom side - must be soldered to ≥200 mm² copper pour for thermal management. |
Key Features
| Feature | Design Value |
|---|---|

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-10SQ080H-M3 | Same 80 V/10 A rating but TO-252 package; RthJ-A = 50 °C/W; VF = 0.82 V @ 10 A. | Requires larger PCB area and external heatsink above 6 A continuous. | Choose when legacy TO-252 footprint compatibility is required and thermal budget allows +10 °C rise. |
| ON Semiconductor SB1080 | 80 V/10 A in SMB package; VF = 0.85 V @ 10 A; Tj max = 150 °C; no exposed thermal pad. | Limited to ≤5 A continuous in open-air conditions due to higher thermal resistance. | Select only for cost-sensitive, low-power (<25 W), non-thermally constrained applications. |
Compared with VS-10SQ080H-M3 and SB1080, STPS10SM80CFP delivers superior thermal performance and lower conduction loss in space-constrained, high-efficiency designs-making it optimal for modern 5x6 footprint-limited power stages requiring >94% efficiency at full load.

FAQ
What is the maximum allowable PCB copper area for optimal thermal performance?
The STPS10SM80CFP requires a minimum 200 mm² exposed copper pour connected to its cathode pad via ≥4 thermal vias (0.3 mm diameter, filled with solder). Larger copper areas (≥400 mm²) reduce RthJ-A to 28 °C/W, enabling 10 A operation at 70 °C ambient without airflow.
Can this diode replace a silicon PN rectifier in an existing 65 kHz flyback design?
Yes-its zero reverse recovery eliminates snubber losses and reduces MOSFET voltage overshoot. However, verify that the original design's layout accommodates the PowerFLAT™ 5x6 footprint and that the cathode pad is fully soldered to a thermal plane; no gate drive changes are needed since it's a passive rectifier.
Is STPS10SM80CFP qualified for automotive applications?
No-this part is not AEC-Q101 qualified and lacks automotive-specific screening. It is rated for industrial temperature range (–65 °C to +175 °C), but ST does not guarantee performance in automotive environments such as under-hood or infotainment systems without additional qualification testing by the end user.
Does the device require derating at elevated ambient temperatures?
Yes-derating begins at 110 °C case temperature. At 85 °C ambient with 200 mm² copper, maximum continuous current is 10 A. At 100 °C ambient, current must be limited to 7.2 A to maintain TJ ≤ 175 °C, per the thermal curve in ST's datasheet Figure 7.
