TVS Diodes 1500 Watt Zener Transient Voltage Suppressors Pb 1N6267A Series Description These devices are designed to protect voltage sensitive components from high voltage, highenergy transients. They have excellent clamping capability, high surge capability, low zener impedance an d fast response time. These devices are Littelfuses exclusive, cost-effective, highly reliable, axial leaded package and are ideally-suited for use in communication systems, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications, to protect CMOS, MOS and Bipolar integrated circuits.

Maximum Uni-directional ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1.
