UMAFxxxA Overview
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.
UMAFxxxA 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-in stress relief with similar COE as PC boards
- Lead-Free construction externally and internally
- Optional Lead-Tin finish (UMA5.0A-170CA)
UMAFxxxA Applications
- Protects sensitive ponents such as IC’s, CMOS, 2 Bipolar, BiCMOS, ECL, DTL, T L, etc
- Protection from switching transients & induced RF
- pliant to IEC61000-4-2 and IEC61000-4-4 for ESD and EFT protection respectively
