DO-201

Q:What defines the physical structure of DO-201?

A:Key features include:
- Axial leads: Robust through-hole mounting with radial wire terminals.
- Cylindrical body: Standardized glass or epoxy-coated housing.
- Size consistency: Diameter of 3.5 mm and typical length of 8.5 mm.
- Polarity marking: Color bands or notches for cathode identification.

Q:Why choose DO-201 over alternatives?

A:Critical advantages:
- High current handling: Supports up to 1A continuous current (vs. smaller axial packages).
- Mechanical durability: Reinforced leads resist bending during insertion.
- Cost-effectiveness: Low-cost solution for through-hole designs.
- Proven reliability: Widely used in industrial environments for decades.

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Dimensions: 3.5 mm (dia.) × 8.5 mm (length).
- Lead Diameter: 0.6 mm (typical).
- Material: Epoxy resin body, copper alloy leads.
- Temp Range: -65°C to +175°C (junction temperature).
- Voltage Rating: Up to 200V (depends on component type).

Q:Where is DO-201 typically applied?

A:Dominant use cases:
- Power rectification: Diodes (e.g., 1N400x series).
- Surge protection: TVS diodes in industrial equipment.
- LED drivers: High-current rectifiers in lighting systems.
- Automotive electronics: Under-hood components requiring robustness.

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Hole Size: 0.8–1.0 mm diameter for lead insertion.
- Soldering: Wave soldering with 260°C max peak temperature.
- Lead Bending: Avoid sharp bends (<90°) near the body to prevent stress cracks.
- Inspection: Visual checks for proper seating and solder fillets.
