TO-251-3 Short Leads, IPak, TO-251AA
TO-251-3 Short Leads, IPak, TO-251AA
The TO-251-3 Short Leads, IPak, TO-251AA (Full Name) is a surface-mount package designed for high-power applications. Featuring short leads, exposed thermal pad, and compact design, it delivers compact footprint and superior thermal dissipation. Typical dimensions are 6.5 mm x 9.8 mm x 2.3 mm with a 2.54 mm pin pitch, making it ideal for power management ICs, switching power supplies, and motor drives. Its exposed thermal tab enables direct PCB thermal transfer, while RoHS-compliant materials ensures reliability in industrial environments.

Q:What defines the physical structure of TO-251-3 Short Leads (IPak/TO-251AA)?
A:Key features include:
- Shortened leads: Optimized for space-constrained PCB designs.
- Central thermal pad: Enhances heat dissipation (covers ~60% of package base).
- 3-pin layout: Single-row inline configuration for simplified routing.
- Robust body: Molded epoxy resin with a typical thickness of 2.3 mm. -
Q:Why choose TO-251-3 Short Leads over alternatives?
A:Critical advantages:
- Miniaturization: 30% smaller footprint than TO-252 (DPak) equivalents.
- Thermal Performance: Direct PCB heat sinking via exposed pad.
- Electrical Benefits: Low-inductance leads for stable power delivery.
- Reliability: Moisture-resistant (MSL3) and halogen-free material. -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 6.5 × 6.1 mm
- Height: 2.3 mm
- Pin Pitch: 2.3 mm
- Material: Copper-alloy leads with matte tin plating.
- Temp Range: -40°C to +150°C. -
Q:Where is TO-251-3 Short Leads typically applied?
A:Dominant use cases:
- Power Management: DC-DC converters (e.g., LM2675).
- Automotive Electronics: LED drivers, motor control.
- Industrial Systems: Relay drivers, power switches. -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: Use 4+ thermal vias under the pad for optimal heat transfer.
- Solder Paste: Type 3 or 4 recommended for fine-pitch printing.
- Reflow Profile: Peak temperature ≤ 250°C (Pb-free process).
- Inspection: Visual/AXI required to verify pad solder fillets.
