DO-15

Q:What defines the physical structure of DO-15?

A:Key features include:
- Axial leaded design: Through-hole mounting with leads extending from both ends.
- Cylindrical body: Glass-encapsulated package with a cylindrical shape.
- Standardized dimensions: Body diameter of 3.5 mm and lead spacing of 7.62 mm.
- Robust construction: Hermetic sealing for environmental protection.

Q:Why choose DO-15 over alternatives?

A:Critical advantages:
- Space efficiency: Compact axial design saves PCB space compared to radial packages.
- High power handling: Supports higher current/voltage (e.g., 1A/200V) than smaller SMD alternatives.
- Reliability: Glass-sealed body resists moisture and thermal cycling.
- Cost-effective: Low-cost solution for through-hole applications.

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Size: 3.5 mm (diameter) × 7.62 mm (lead spacing).
- Height: ~5 mm (including leads).
- Lead Diameter: 0.45–0.6 mm.
- Material: Glass body with copper-alloy leads.
- Temp Range: -65°C to +175°C (military-grade options available).

Q:Where is DO-15 typically applied?

A:Dominant use cases:
- Power diodes: Rectifiers (e.g., 1N400x series).
- Voltage regulation: Zener diodes (e.g., 1N47xx series).
- Industrial electronics: Surge protection and snubber circuits.

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Design: Ensure adequate hole spacing (7.62 mm) and lead bending clearance.
- Soldering: Wave or hand soldering at 260°C max to avoid glass cracking.
- Inspection: Visual checks for lead integrity and glass seal defects.
- Storage: Keep in dry environments to prevent lead oxidation.
