500 Watt Axial Leaded TVS
FEATURES:
• 500 Watts Peak Pulse Power (tp = 10/1000µs)
• Voidless hermetically sealed glass package
• Metallurgically bonded
• High surge capacity
• Unidirectional
• Available in JTX, and JTXV versions per
MIL-S-19500/551
DESCRIPTION
The 1N64xx series of transient voltage suppressors are
designed to protect military and commercial electronic
equipment from overvoltages caused by lightning, ESD,
EFT, inductive load switching, and EMP. These devices are
constructed using a p-n junction TVS diode in a
hermetically sealed, voidless glass package. The
hermetically sealed package provides high reliability in
harsh environmental conditions. TVS diodes are further
characterized by their high surge capability, low operating
and clamping voltages, and a theoretically instantaneous
response time. This makes them ideal for use as board
level protection for sensitive semiconductor components.
These devices are DESC QPL qualified to
MIL-S-19500/551.
MECHANICAL CHARACTERISTICS:
• Hermetically sealed glass package
• Tinned copper leads
• Marking : P/N, date code, logo, & cathode band
