DESCRIPTION APPEARANCE
These surface mount Transient Voltage Suppressors (TVSs) are used for protecting
sensitive components requiring low clamping voltage levels. They are rated at high
current impulses typically generated by inductive switching transients. Other
benefits are achieved with low-profile surface mount J-bend or Gull-wing terminals
for stress-relief and lower weight. Its low-flat profile provides easier insertion or
automatic handling benefits compared to other MELF style packages. Options for
screening similar to JAN, JANTX, JANTXV, and JANS also exist by using MQ, MX,
MV or MSP respectively for part number prefixes and high reliability screening in
accordance with MIL-PRF-19500/507.

FEATURES APPLICATIONS / BENEFITS
• Working Standoff Voltages: 5.5 volts to 171 volts
• Metallurgically bonded
• Reliability data per JESD22-A108, JESD22-A104,
JESD22-A113-B, JESD22-A101-B, and JESD22-A102
• Thermally efficient surface mount with J-bends or
Gull wings termination for stress relief (flat handling
surface and easier placement)
• Options for screening in accordance with MIL-PRF-
19500/500 for JAN, JANTX, JANTXV, and JANS are
available by adding MQ, MX, MV, or MSP prefixes
respectively to part numbers. For example,
designate a MXSMCJ5629A for a JANTX screen.
• For high reliability transient voltage suppression in
low profile surface mount locations requiring easy
placement and strain relief
• Light weight for airborne or satellite applications
• Superior surge quality to protect from ESD and EFT
transients per IEC61000-4-2 and -4-4
• Lightning surge protection per IEC61000-4-5 for
Class 1 and 2 with source impedance of 42 Ohms as
well as Class 3 and 4 selectively at lower voltages
(VWM) and higher surge current (IPP) ratings herein
• Protects sensitive components such as ICs, CMOS,
Bipolar, BiCMOS, ECL, DTL, T2L, etc.
