DPAK-5
DPAK-5
The DPAK-5 (TO-252-5) is a surface-mount package designed for power semiconductor devices. Featuring **five electrical terminals**, a **large exposed thermal pad**, and a **compact footprint**, it delivers **superior heat dissipation** and **space efficiency on PCBs**. Typical dimensions are **6.73×6.22 mm** with a **1.27 mm** pin pitch and a **2.3 mm** height, making it ideal for **DC-DC converters**, **motor drivers**, and **battery management systems**. Its **central bottom thermal pad** enables direct PCB thermal transfer, while **RoHS-compliant materials** ensures reliability in industrial environments.

Q:What defines the physical structure of DPAK-5?
A:Key features include:
- Leadless bottom-mounted pads: Ensures stable PCB attachment.
- Central thermal pad: Provides ~70% coverage for efficient heat dissipation.
- 5-pin layout: Asymmetric arrangement for optimized power routing.
- Ultra-thin profile: 1.0 mm height for space-constrained designs. -
Q:Why choose DPAK-5 over alternatives?
A:Critical advantages:
- Miniaturization: 40% smaller footprint than TO-252 (DPAK).
- Thermal Performance: Direct PCB heat path reduces junction-to-board thermal resistance by 30%.
- Electrical Benefits: Low-inductance design (<1 nH) for high-frequency stability.
- Reliability: Moisture-resistant (MSL3) substrate for harsh environments. -
Q:What are common technical specs?
A:Standard configurations (consult datasheets):
- Body Size: 6.5 × 6.0 mm
- Height: 1.0 mm
- Pin Pitch: 1.27 mm
- Material: Copper-alloy leads with matte-tin plating.
- Temp Range: -40°C to +150°C (operational). -
Q:Where is DPAK-5 typically applied?
A:Dominant use cases:
- Power Converters: Buck/boost ICs (e.g., TI TPS54332).
- Motor Drivers: H-bridge modules (e.g., DRV8873).
- Automotive Systems: LED drivers and ECU power supplies. -
Q:What are critical assembly guidelines?
A:Key recommendations:
- PCB Design: 4×4 thermal vias under pad (0.3 mm diameter).
- Solder Paste: Type 4 (20–38 μm particle size) recommended.
- Reflow Profile: Peak temp ≤ 250°C (Pb-free process).
- Inspection: X-ray (AXI) mandatory for void detection (<15% tolerance).
