DO-35

Q:What defines the physical structure of DO-35?

A:Key features include:
- Glass-sealed body: Hermetic protection for sensitive components.
- Axial lead configuration: Two leads extending from opposite ends.
- Compact cylindrical design: Diameter of 2.0 mm and length of 4.1 mm.
- Lightweight construction: Ideal for space-constrained applications.

Q:Why choose DO-35 over alternatives?

A:Critical advantages:
- Miniaturization: 30% smaller than similar glass diodes (e.g., DO-41).
- Thermal Performance: Efficient heat dissipation through axial leads.
- Electrical Benefits: Low parasitic capacitance for high-frequency applications.
- Reliability: Hermetic sealing ensures moisture and contaminant resistance.

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Size: 2.0 mm (diameter) × 4.1 mm (length).
- Lead Diameter: 0.5 mm.
- Material: Glass body with nickel-plated leads.
- Temp Range: -65°C to +175°C.
- Max Forward Current: 500 mA (typical).

Q:Where is DO-35 typically applied?

A:Dominant use cases:
- Signal Diodes: RF and switching circuits (e.g., 1N4148).
- Voltage Regulation: Low-power Zener diodes (e.g., BZX55 series).
- Sensor Protection: ESD/transient suppression in IoT devices.

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Design: Ensure adequate lead spacing (≥ 2.54 mm).
- Soldering: Manual or wave soldering (max 260°C for 10 sec).
- Handling: Avoid excessive bending of axial leads.
- Inspection: Visual check for glass cracks or lead misalignment.
