P4SMAJxxADF D-FLAT 400 W TVS Diode

Diodes Incorporated introduces their 400 W TVS series which is housed in the new ultra-thin, surface-mount, D-FLAT package. This high-performance, flat-lead package is designed with low thermal resistance to provide high-power dissipation. In addition, the creepage distance has been maximized to enhance isolation between terminals against tracking. Furthermore, with a height of only 1.1 mm maximum, the D-FLAT package is also 54% thinner than the conventional SMA package to enable space-constrained designs. The P4SMAJxxADF series is comprised of 29 high-power unidirectional TVS devices, available with a large selection of reverse standoff voltages from 5 V to 85 V. These devices have excellent ESD immunity, exceeding ±30 kV IEC-61000-4-2 ESD level 4 for air and contact discharge. Additionally, with low leakage current at 1 μA for most of the range, energy efficiency is improved. These devices are ideally suited for general ESD protection in industrial applications and consumer and portable electronics. The D-FLAT package is fully green and RoHS-compliant.

Features

• Exceeds IEC 61000-4-2 ESD level 4 contact and air discharge
  • Superb ESD protection, exceeding ±30 kV for contact and air discharge
• GPP TVS with large selection of reverse standoff voltages
  • The P4SMAJxxADF series uses a GPP construction which protects the junction from ambient contamination and mechanical damage. Additionally, the P4SMAJxxADF series has a large selection of reverse working voltages, ranging from 5 V to 85 V, which cover most design requirements
• Excellent thermal transfer properties and lower ultra-thin profile
  • The flat lead design of the D-FLAT package (5.6 mm x 2.95 mm maximum) improves thermal performance. The height of 1.1 mm maximum enables applications of ultra-thin profile
• 400 W of power dissipation
  • These devices are capable of dissipating 400 W of peak pulse power

Applications

• Protection of I/O channels
• DC power bus protection
