TO92S

Q:What defines the physical structure of TO92S?

A:Key features include:
- 3-pin plastic package: Compact and lightweight design.
- Inline pin layout: Pins arranged linearly for easy PCB mounting.
- Standard lead spacing: 2.54 mm (0.1 inch) pitch for compatibility.
- Low-profile body: Typical height of ~4.5 mm.

Q:Why choose TO92S over alternatives?

A:Critical advantages:
- Cost-effective: Lower production cost than SMD alternatives.
- Hand-solder friendly: Through-hole design simplifies prototyping.
- Robust mechanical stability: Durable plastic casing resists physical stress.
- Wide compatibility: Compatible with breadboards and perfboards.

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Size: 4.5 × 4.0 mm (typical).
- Height: ~4.5 mm.
- Pin Pitch: 2.54 mm.
- Material: Molded plastic with tin-plated leads.
- Temp Range: -55°C to +150°C (operational).

Q:Where is TO92S typically applied?

A:Dominant use cases:
- Discrete transistors: e.g., 2N3904/BC547 in amplification circuits.
- Voltage regulators: e.g., LM78L05 for low-power applications.
- Sensors: e.g., Temperature sensors (LM35) and optocouplers.

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Design: Ensure hole diameter ≥ 0.8 mm for lead insertion.
- Soldering: Use leaded or lead-free solder (max 260°C for 10 sec).
- Handling: Avoid excessive bending of leads to prevent breakage.
- Inspection: Visual checks for proper pin alignment and solder fillets.
