Product details
Overview
BYW80-200 from STMicroelectronics is a high-efficiency fast recovery rectifier diode in TO-220AC package, rated for 200 V repetitive peak reverse voltage, 10 A average forward current at Tc=120°C, and 35 ns maximum reverse recovery time. It delivers very low forward losses (VF ≤ 0.85 V at 7 A, 125°C) and high surge capability (100 A, 10 ms), making it suitable for switch-mode power supplies and DC–DC converters.
For engineers reviewing the BYW80-200 datasheet, BYW80-200 pinout, BYW80-200 application, or BYW80-200 equivalent, key selection criteria include its fast trr (≤35 ns), low thermal resistance (Rth(j–c) = 2.5 °C/W), insulated package option compatibility, and validated performance in high-frequency freewheeling and polarity protection circuits.
Technical Context
This diode operates as a unidirectional, single-chip silicon rectifier optimized for high-frequency switching applications. Its fast recovery behavior is characterized by low QRR (recovery charge) and negligible switching losses due to controlled minority-carrier lifetime control.
The device exhibits stable reverse leakage (IR ≤ 1 mA at 100°C, VR = VRRM) and predictable forward conduction (VF = 0.85–1.15 V across 7–15 A, 25–125°C), enabling accurate loss modeling using P = 0.65 × IF(AV) + 0.027 × IF²(RMS).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage without breakdown; defines safe operating range in flyback/freewheeling topologies. |
| IF(AV) | 10 A at Tc = 120°C - Continuous DC output current capability with heatsink; sets minimum heatsink sizing requirement. |
| trr (max) | 35 ns - Reverse recovery time under IF = 1 A, dIF/dt = −50 A/µs; determines minimum dead-time and EMI profile in hard-switched SMPS. |
| VF (max) | 0.85 V at IF = 7 A, Tj = 125°C - Forward voltage drop defining conduction loss at typical operating point; enables <1 W loss at 10 A RMS. |
| Rth(j–c) | 2.5 °C/W - Junction-to-case thermal resistance (TO-220AC); allows direct calculation of junction temperature rise above heatsink base. |
| IFSM | 100 A, tp = 10 ms (sinusoidal) - Non-repetitive surge rating; supports inrush current handling in AC-input rectification stages. |
Pinout & Package
BYW80-200 is housed in a TO-220AC package with electrically isolated tab (non-insulated version), featuring three terminals: Anode, Cathode, and metal tab (electrically connected to cathode). Mounting torque must not exceed 1.0 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to input/high-side node in rectifier configuration; polarity-sensitive for correct conduction direction. |
| Cathode | Forward current exit terminal | Electrically tied to metal tab in TO-220AC; requires insulating washer if mounted to grounded heatsink. |
| Tab (Cathode) | Thermal and electrical interface | Serves dual role: primary heat path to heatsink and cathode connection; mandates mechanical isolation when system ground reference differs. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | trr ≤ 35 ns ensures minimal switching loss and reduced EMI in 50–500 kHz SMPS designs. |
| Low forward voltage | VF ≤ 0.85 V at 7 A/125°C reduces conduction loss by ~25% vs. standard recovery diodes at same current. |
| High surge rating | IFSM = 100 A (10 ms) supports robust operation during line surges and startup transients in offline PSUs. |
| Thermal efficiency | Rth(j–c) = 2.5 °C/W enables compact heatsinking-junction rise limited to 25°C at 10 W dissipation. |
Applications
| Switch-Mode Power Supply Output Rectification | DC–DC Converter Freewheeling Diode |
|---|---|
|
Use Scenario: Secondary-side rectification in 100–300 W offline flyback or forward converters. IC Role / Device Role / Timing Role: Unidirectional current valve synchronizing with primary-side MOSFET switching; conducts during off-time. Use Value: 35 ns trr minimizes reverse recovery ringing and reduces snubber losses, improving efficiency by up to 1.2% at 100 kHz. |
Use Scenario: Freewheeling path in synchronous and non-synchronous buck converters (12 V → 3.3 V/5 V). IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side switch off-time; handles peak inductor current. Use Value: VF ≤ 0.85 V at 7 A lowers conduction loss by 0.4 W vs. standard FRD, directly improving light-load efficiency. |
| Polarity Protection Circuit | Low-Voltage Inverter Output Stage |
|
Use Scenario: Reverse-voltage blocking in 12–48 V battery-powered systems (e.g., PoE injectors, telecom shelves). IC Role / Device Role / Timing Role: Series-connected anode-in configuration; blocks reverse current while passing forward load current. Use Value: IR ≤ 1 µA at 25°C and ≤1 mA at 100°C ensures negligible standby leakage, preserving battery life over extended idle periods. |
Use Scenario: Output rectification in 24 V–400 V DC inverters for motor drives and UPS systems. IC Role / Device Role / Timing Role: High-current, high-frequency rectifier in H-bridge or half-bridge output stage; handles bidirectional reactive energy. Use Value: 100 A IFSM rating withstands motor stall currents and inductive kickback without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600 V VRRM, 10 A IF(AV), trr = 30 ns, TO-220AC | Higher voltage rating suits 400 V bus designs; lower VF (0.79 V) improves conduction efficiency. | Select when >300 V reverse stress exists or lower VF is prioritized over cost. |
| ES1J | 600 V VRRM, 1 A IF(AV), trr = 35 ns, DO-204AL | Lower current rating and smaller package; unsuitable for >2 A continuous loads. | Only acceptable for signal-level or low-power auxiliary rails-not a drop-in replacement for BYW80-200's 10 A capability. |
Compared with STTH10R06DJF and ES1J, BYW80-200 uniquely balances 200 V rating, 10 A average current, and 35 ns trr in TO-220AC-making it optimal for cost-sensitive, medium-power SMPS where higher voltage margin is unnecessary and thermal mass matters.

FAQ
Is BYW80-200 electrically insulated?
No-BYW80-200 uses the standard TO-220AC package where the metal tab is electrically connected to the cathode. For insulated mounting, use BYW80F-200 (ISOWATT220AC) or BYW80FP-200 (TO-220FPAC), both rated for 2000 V DC insulation between tab and leads.
What is the maximum recommended mounting torque for BYW80-200?
The maximum torque for BYW80-200 in TO-220AC is 1.0 N·m. Exceeding this risks mechanical damage to the leadframe or die attach. ST recommends 0.8 N·m for optimal thermal contact and long-term reliability.
Can BYW80-200 replace BYW80-100 in existing designs?
Yes-BYW80-200 is backward compatible with BYW80-100 in all electrical and mechanical aspects except VRRM (200 V vs. 100 V). No layout or thermal changes are needed, but verify reverse voltage stress does not exceed 100 V in legacy designs before substitution.
How does junction capacitance affect BYW80-200 in high-frequency operation?
BYW80-200 has a typical junction capacitance of 12 pF at VR = 4 V. This low Cj minimizes displacement current during voltage transitions, reducing gate drive loading on synchronous MOSFETs and limiting high-frequency noise coupling in tightly regulated SMPS layouts.
