SOT-23-3
SOT-23-3
The SOT-23-3 (Small Outline Transistor 23-lead, 3-pin variant) is a surface-mount package designed for high-density circuits. Featuring ultra-compact footprint, gull-wing lead design, and low-profile height, it delivers significant space savings on PCBs and enhanced electrical performance in constrained layouts. Typical dimensions are 2.9 mm × 1.3 mm with a 0.95 mm pin pitch and 1.0 mm height, making it ideal for small-signal transistors, diodes, and voltage regulators in portable electronics. Its exposed leadframe construction enables efficient thermal dissipation, while RoHS-compliant materials ensure reliability in industrial environments.

Q:What defines the physical structure of SOT-23-3?
A:Key features include:
- Compact 3-pin layout: Asymmetric gull-wing leads for space efficiency.
- Miniature footprint: 2.9 mm × 1.6 mm body size.
- Low profile: 1.0 mm typical height.
- Standardized pinout: Pin 1 (input), Pin 2 (GND), Pin 3 (output). -
Q:Why choose SOT-23-3 over alternatives?
A:Critical advantages:
- Miniaturization: 60% smaller than TO-92 packages.
- Thermal Performance: Exposed pad variants (e.g., SOT-23-3L) enable direct PCB heat dissipation.
- Electrical Benefits: Low-inductance (<1 nH) leads for high-frequency stability.
- Reliability: Moisture-resistant (JEDEC Level 3) molded epoxy body. -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 2.9 mm × 1.6 mm.
- Height: 1.0 mm (max 1.3 mm).
- Pin Pitch: 0.95 mm (lead-to-lead spacing).
- Material: Copper-alloy leads with matte Sn plating.
- Temp Range: -55°C to +150°C (operational). -
Q:Where is SOT-23-3 typically applied?
A:Dominant use cases:
- Discrete Semiconductors: BJTs (e.g., MMBT3904), MOSFETs (e.g., 2N7002).
- Analog ICs: Voltage regulators (e.g., LM1117-3.3).
- Sensor Interfaces: Signal conditioning circuits (e.g., temperature sensors). -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: 0.2 mm solder mask clearance around pads.
- Solder Paste: Type 3 (particle size 25–45 μm) recommended.
- Reflow Profile: Peak temp ≤ 260°C (Pb-free process).
- Inspection: Optical inspection (AOI) for lead coplanarity.
