BYW29-200G

BYW29-200G is a fast/ultrafast recovery diode in the BYW29 family. It’s used as a high-speed rectifier in switching power supplies, DC-DC converters, and freewheeling paths in motor drives.
Key points:
- Likely reverse voltage around 200 V (VRRM) and about 1 A average forward current, with higher surge capability.
- Very fast reverse-recovery times (nanoseconds to tens of nanoseconds range in typical submodels).
- RoHS lead-free variant (the “G” suffix often denotes green/lead-free packaging).
- Available in various packages (e.g., through-hole TO-220 or surface-mount DPAK/D2PAK), depending on the exact variant.
Usage tip:
- Connect anode to the switch side and cathode to the freewheeling/load side; ensure proper heat sinking for higher currents.
Note:
- Check the exact datasheet for BYW29-200G, as ratings and packaging can vary by manufacturer and submodel.

Do you mean the BYW29-200G ultrafast recovery diode? I can list cross-reference equivalents, but I need to confirm the exact specs (Vr = 200 V, If(AV), package, recovery time). Please confirm or paste the datasheet/specs and I’ll provide equivalent part numbers.

Function: BYW29-200G is a fast-recovery/high-voltage rectifier diode. It conducts current from anode to cathode in forward bias and blocks reverse voltage when off, with a short reverse-recovery time suited for switching/rectification tasks (e.g., switching power supplies, freewheeling diodes, snubbers).

The BYW29-200G is manufactured by Vishay Intertechnology (Vishay), specifically under its semiconductor/discrete components product lines. Vishay is a multinational electronics manufacturer that designs and produces discrete semiconductors (diodes, transistors, MOSFETs), passive components (resistors, capacitors, inductors), and sensors. Founded in 1962 and headquartered in Malvern, Pennsylvania, it is a publicly traded supplier to industrial, automotive, telecom, and consumer electronics markets.

BYW29-200G is a high‑current fast‑recovery diode. Typical applications include:
- Rectification and freewheeling in high‑power switch‑mode power supplies (SMPS) and PFC circuits
- DC‑link rectification in inverters and motor‑drive systems
- Power supplies for UPS, welding equipment, and telecom/industrial systems
- Solar/renewable energy inverter interfaces
- Snubber/auxiliary rectifier stages in high‑power converters
These use cases cover its role as a robust high‑current rectifier in modern power electronics.

The BYW29-200G is a glass-passivated, axial-leaded fast-recovery rectifier typically supplied in a DO-41 (axial) package.
