Product details
Overview
BYW80FP-200 from STMicroelectronics is a high-efficiency fast recovery rectifier diode in insulated TO-220FPAC package, rated for 200 V repetitive peak reverse voltage, 20 A RMS forward current, and 100 A non-repetitive surge current. It delivers low conduction loss (VF ≤ 0.85 V at 7 A, 125°C) and ultrafast switching (trr ≤ 35 ns), making it suitable for high-frequency switch-mode power supplies and DC–DC converters.
For engineers reviewing the BYW80FP-200 datasheet, BYW80FP-200 pinout, BYW80FP-200 application, or BYW80FP-200 equivalent, key selection criteria include its 2000 V DC insulation rating, 4.7 °C/W junction-to-case thermal resistance, and validated performance in free-wheeling and polarity protection circuits under high dI/dt conditions.
Technical Context
This diode employs a single-chip silicon PN junction optimized for fast recovery with negligible switching losses and high surge tolerance. Its design targets high-frequency operation up to several hundred kHz in SMPS topologies where low trr and controlled QRR are critical to minimize EMI and improve efficiency.
The TO-220FPAC package provides electrical isolation (2000 V DC) and mechanical robustness, enabling direct mounting on heatsinks without insulating washers. Thermal performance is characterized by Rth(j-c) = 4.7 °C/W and Tj(max) = +150°C, supporting continuous operation in compact, thermally constrained industrial power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum reverse blocking voltage before breakdown; ensures safe operation in 12–48 V output SMPS with margin against transients. |
| IF(RMS) | 20 A - Sustained AC-equivalent forward current; supports high-power secondary-side rectification in 300–500 W converters. |
| trr (max) | 35 ns - Measured at IF = 0.5 A, IR = 1 A, dIF/dt = −50 A/µs; enables clean commutation in hard-switched flyback and forward converters. |
| VF (max) | 0.85 V at IF = 7 A, Tj = 125°C - Low forward drop reduces conduction loss; Pcond ≈ 0.65×IF(AV) + 0.027×IF²(RMS) per datasheet equation. |
| Rth(j-c) | 4.7 °C/W - Junction-to-case thermal resistance for TO-220FPAC; defines minimum heatsink requirement for thermal management at full load. |
| IFS M | 100 A (tp = 10 ms, sinusoidal) - Peak non-repetitive surge capability; handles inrush and fault currents in industrial power supplies. |
| CJ | 12 pF - Junction capacitance at VR = VRRM; contributes to high-frequency switching behavior and EMI profile. |
Pinout & Package
BYW80FP-200 is housed in an insulated TO-220FPAC package (JEDEC outline), featuring electrically isolated metal tab rated for 2000 V DC. The device has two terminals: anode and cathode, with the metal tab serving as the cathode connection and providing thermal path to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Soldered to transformer secondary or switching node; must withstand peak reverse voltage during off-state. |
| Cathode (Metal Tab) | Forward current exit / heat sink interface | Electrically isolated tab serves as cathode and primary thermal path; requires torque of 0.55 N·m (recommended) for reliable thermal contact. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | trr ≤ 35 ns ensures minimal reverse recovery charge (QRR) and reduced switching loss in high-frequency SMPS. |
| High surge current rating | 100 A IFSM (10 ms) supports robustness against line surges and startup inrush in industrial power adapters. |
| Insulated package | TO-220FPAC provides 2000 V DC isolation between tab and leads, eliminating need for insulating hardware in chassis-grounded designs. |
| Low forward voltage | VF ≤ 0.85 V at 7 A/125°C directly lowers conduction loss and improves system efficiency at elevated temperatures. |
| Thermal reliability | Junction temperature range −65°C to +150°C enables operation in harsh environments including motor drives and telecom rectifiers. |

FAQ
What is the maximum junction temperature for BYW80FP-200?
The absolute maximum junction temperature is +150°C, verified per datasheet Section "Absolute Maximum Ratings". Operation at this limit requires strict thermal design-Rth(j-c) = 4.7 °C/W mandates heatsink thermal resistance ≤ 1.3 °C/W to maintain Tj ≤ 150°C at 20 A RMS with Tamb = 75°C.
Is BYW80FP-200 pin-compatible with BYW80F-200?
No-BYW80FP-200 uses TO-220FPAC (insulated tab, cathode on tab), while BYW80F-200 uses ISOWATT220AC (also insulated, but different mechanical footprint and torque spec). Both share identical electrical specs, but mechanical mounting and thermal interface differ; PCB layout and heatsink interface must be redesigned.
How does the 2000 V DC insulation rating impact system safety?
The 2000 V DC isolation between the metal tab and leads meets reinforced insulation requirements per IEC 60950-1 for primary-to-secondary barrier applications. This eliminates need for additional insulating hardware in Class I power supplies, reducing assembly cost and improving thermal reliability.
Can BYW80FP-200 replace standard UF4007 diodes in high-frequency designs?
Yes-its 35 ns trr and 0.85 V VF outperform UF4007 (trr ≈ 75 ns, VF ≈ 1.7 V @ 1 A), delivering lower switching loss and EMI. However, BYW80FP-200's 20 A RMS rating and TO-220FPAC package require revised thermal and mechanical design versus DO-41-packaged UF4007.
