DESCRIPTION
These 500 watt transient voltage suppressors offer capabilities only found in larger packages. 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 BA package outlines except with a much lower profile height. Its robust configuration in a “2010” style MELF package prevents damage to extended-lead terminals and virtually eliminates inductive parasitics from fast rise-time transients with very short internal/external conduction paths. They are also very effective in protection from ESD or EFT per IEC61000-4-2 and IEC61000-4-4.
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 (approximately 1 mm)
• Available on Tape and Reel
• Built-in stress relief with similar COE as PC boards
• Optional Lead-Free design/finish (UMAF5.0A-170CA)
• Options for screening in accordance with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers.
APPLICATIONS / BENEFITS
• Protects sensitive components such as IC’s, CMOS, Bipolar, BiCMOS, ECL, DTL, T2L, etc.
• Protection from switching transients & induced RF
• Compliant to IEC61000-4-2 and IEC61000-4-4 for ESD and EFT protection respectively
• Secondary lightning protection per IEC61000-4-5 with 42 Ohms source impedance:
Class 1: UMA5.0 to UMA100A or CA
Class 2: UMA5.0 to UMA51A or CA
Class 3: UMA5.0 to UMA24A or CA
Class 4: UMA5.0 to UMA12A or CA
• Secondary lightning protection per IEC61000-4-5 with 12 Ohms source impedance:
Class 1: UMA5.0 to UMA30A or CA
Class 2: UMA5.0 to UMA16A or CA
• Virtually zero inductive parasitics with minimal Ldi/dt voltage overshoots for fast-rise-time transients
