SiRA20DP: Vishay’s N-Channel 25 V (D-S) MOSFET Offering High Efficiency and Best-in-Class Resistance

By Sarah RonkoskeJuly 9, 2017

In the fifth and the final part of the Vishay Super 12 series, we’ll discuss Vishay’s new 25 V N-Channel TrenchFET® Power MOSFET.

Introduced by Vishay Intertechnology — a global manufacturer of premium quality semiconductors and passive electronic components — the 25 V N-Channel TrenchFET® Power MOSFET offers industry-low on-resistance down to 0.58 mΩ at 10 V.

Named SiRA20DP, the N-Channel 25 V (D-S) MOSFET is a part of the next-generation TrenchFET® Gen IV power MOSFETs introduced by Vishay/Siliconix. The TrenchFET® Gen IV family reduces on-resistance times silicon area of more than 60% compared to previous-generation devices, obtaining the best-in-class resistance for reduced power consumption and higher efficiency.

Key Features of Vishay Siliconix SiRA20DP N-Channel 25 V (D-S) MOSFET

SiRA20DP increases power density, and reduces conduction power loss, while its low gate charge of 61 nC enables high efficiency for DC/DC conversion. Key features of the SiRA20DP N-Channel 25 V (D-S) MOSFET include:

  • TrenchFET® Gen IV power MOSFET
  • Optimized Qg, Qgd, and Qgd/Qgs ratio reduces switching related power loss
  • 100 % Rg and UIS tested
