Product details
Overview
STPS30SM80CG-TR from STMicroelectronics is a dual-channel power Schottky rectifier in insulated TO-220FPAB package, rated for 80 V repetitive peak reverse voltage and 2 × 15 A average forward current per diode at TC = 105 °C. It delivers low forward voltage drop (0.515 V typ. at 15 A, 125 °C), low leakage (7 mA max. at 125 °C, VR = VRRM), and avalanche-rated operation (100 V, 22.8 A pulse), enabling high-efficiency secondary-side rectification in AC/DC adapters for notebooks and LCD TVs.
For engineers reviewing the STPS30SM80CG-TR datasheet, STPS30SM80CG-TR pinout, STPS30SM80CG-TR application, or STPS30SM80CG-TR equivalent, key selection criteria include junction-to-case thermal resistance (5.30 °C/W per diode), insulated package rating (2000 VRMS), dual-diode configuration, avalanche capability, and conduction loss equation (P = 0.520 × IF(AV) + 0.0103 × IF²(RMS)).
Technical Context
This dual Schottky rectifier integrates two independent anode-cathode junctions in a single insulated TO-220FPAB housing, sharing a common heatsink-mounting tab (cathode-connected case). Its design targets high-frequency switching applications where low VF and fast recovery eliminate minority-carrier storage delay.
Thermal coupling between diodes is quantified by Rth(c) = 3.10 °C/W; simultaneous conduction requires junction temperature calculation using ΔTj(diode1) = P(diode1) × 5.30 + P(diode2) × 3.10. Avalanche energy handling is validated per AN1768/AN2025 with PARM = 545 W (tp = 10 µs, Tj = 125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback/freewheeling paths |
| IF(AV) | 2 × 15 A - Average forward current per diode at TC = 105 °C; supports 30 A total device output in dual-phase or interleaved designs |
| VF(typ.) | 0.515 V @ 15 A, 125 °C - Low conduction loss enables >92% efficiency in 19 V/3 A notebook adapters |
| IR(max) | 20 mA @ 125 °C, VR = VRRM - Low leakage preserves standby power budget in Energy Star-compliant systems |
| Rth(j-c) | 5.30 °C/W per diode - Enables thermal design with ≤105 °C case temperature for 15 A continuous conduction |
| VARM | 100 V @ tp < 1 µs - Specifies avalanche clamping level during transient overvoltage events (e.g., MOSFET turn-off spikes) |
| Tj(max) | 175 °C - Allows operation in compact, thermally constrained adapter enclosures without derating |
Pinout & Package
TO-220FPAB is an insulated through-hole package with electrically isolated metal tab (2000 VRMS isolation), three leads, and screw-mount heatsink interface. The tab serves as cathode for both diodes; leads A1 and A2 are anodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Connects to transformer secondary or switch node for first rectification path |
| A2 | Anode of Diode 2 | Independent anode for second rectification path; enables dual-output or interleaved topologies |
| Tab (K) | Common Cathode | Electrically isolated metal tab (2000 VRMS); serves as thermal path and output return node |
Key Features
| Feature | Design Value |
|---|---|
| Insulated TO-220FPAB package | 2000 VRMS isolation enables direct mounting to grounded heatsinks without insulating pads in Class II adapters |
| Avalanche-rated operation | Validated 545 W repetitive avalanche power (tp = 10 µs) improves robustness against inductive switching transients |
| Optimized VF–IR trade-off | 0.515 V VF at 15 A/125 °C with only 7 mA IR ensures low conduction loss without excessive leakage-induced heating |
| High Tj(max) = 175 °C | Permits full-rated current delivery in ambient temperatures up to 85 °C with appropriate heatsinking |
Applications
| Notebook AC/DC Adapters | LCD TV Power Supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG-TR | Higher VRRM = 100 V; higher VF = 0.62 V @ 15 A/125 °C; same TO-220FPAB package | Better suited for 48 V input systems or industrial adapters requiring margin above 80 V | Select when system transient voltage exceeds 85 V or long-term reliability at elevated VR is critical |
| Vishay VS-30CPH08-M3/45-E3 | Same VRRM = 80 V; higher IF(AV) = 30 A per diode; non-insulated TO-247AC package; no avalanche rating | Requires insulating hardware; lacks avalanche validation for high-dV/dt environments | Choose for cost-sensitive, non-isolated designs where thermal performance outweighs safety isolation needs |
Compared with STPS30SM80CG-TR, the STPS30H100CG-TR trades 0.105 V higher VF for 20 V reverse margin and avalanche robustness, while the VS-30CPH08-M3/45-E3 offers higher current rating but forfeits insulation and transient ruggedness-making STPS30SM80CG-TR optimal for safety-critical, space-constrained consumer adapters.

FAQ
Is STPS30SM80CG-TR RoHS compliant and halogen-free?
Yes. STPS30SM80CG-TR carries ECOPACK®2 certification, confirming full RoHS compliance and halogen-free construction per IEC 61249-2-21. The TO-220FPAB package uses epoxy meeting UL 94 V-0 flammability rating, and material declarations are published on ST's official product page.
What is the recommended heatsink mounting torque for the TO-220FPAB tab?
The manufacturer specifies a recommended torque of 0.55 N·m and a maximum torque of 0.7 N·m for the mounting screw. Exceeding 0.7 N·m risks deforming the package or compromising internal die attach integrity, potentially increasing Rth(j-c) beyond the rated 5.30 °C/W per diode.
Can STPS30SM80CG-TR be used in parallel with another identical unit?
No. The device is not characterized for parallel operation due to thermal coupling via the shared insulated tab and mismatched VF drift across temperature. For >30 A applications, use a single higher-rated part (e.g., STPS60SM80CG-TR) or redesign with active synchronous rectification.
Does the 2000 VRMS insulation rating apply to DC or AC voltage?
The 2000 VRMS rating is specified for sinusoidal AC voltage at 50/60 Hz, per IEC 60950-1. For DC isolation, the applicable rating is 2800 VDC (derived from √2 × 2000 VRMS), verified during production hi-pot testing. This supports Class II adapter designs with reinforced insulation requirements.
