UMAFxxxA - Transient Voltage Suppressor

General Description

These 500 watt transient voltage suppressors offer power-handling capabilities only found in larger packages.

They are also environmentally Lead-Free both externally and internally.

Key Features

  • Available as a unidirectional or bidirectional device (bidirectional with CA suffix).
  • Fast response time.
  • Suppresses transients up to 500 W @ 10/1000 µs (see Figure 1, 2, and 3).
  • Robust 2010 MELF style flat package configuration for accurate pick-and-place handling.
  • Fits same small narrow PCB pad layouts as “SMAJ” packages in JEDEC DO-214AC (or BA).
  • Very low height profile (approx 1 mm).
  • Available on Tape and Reel.
  • Built-i.

UMAF5.0A thru UMAF170CA ULTRAMITE™ SURFACE MOUNT 500 Watt SCOTTSDALE DIVISION Transient Voltage Suppressor 5.0 to 170 V ENVIRONMENTALLY LEAD-FREE W W W . Microsemi . COM DESCRIPTION These 500 watt transient voltage suppressors offer power-handling capabilities only found in larger packages. They are also environmentally Lead-Free both externally and internally. They are used for protecting against a variety of transients from inductive switching environments or lower levels of induced secondary lightning effects of IEC61000-4-5. It offers the same size footprint as the popular DO-214AC or PACKAGE configuration www.DataSheet4U.com BA package outlines except with a much lower profile height.
