ECCN 3A228
NPATSwitching devices, as follows .
What This ECCN Covers
ECCN 3A228 controls switching devices meeting the characteristics in the entry — for example certain fast high-voltage switches and related tubes. These pulse and switching components have proliferation-relevant uses and are controlled for Nuclear Nonproliferation and Anti-Terrorism reasons.
Who needs to check this?
Suppliers of high-voltage and fast switching devices for pulsed-power, laser, and research applications.
Compliance tip
Confirm the device against the voltage, current, and timing parameters in the entry. With NP among the reasons, license exceptions are limited — verify the Country Chart and apply nuclear/pulsed-power end-use diligence.
Items Covered
- 1. Containing three or more electrodes;
- 2. Anode peak voltage rating of 2.5 kV or more;
- 3. Anode peak current rating of 100 A or more; and
- 4. Anode delay time of 10 µs or less.
- b.Triggered spark-gaps having both of the following characteristics:
- 1. An anode delay time of 15 µs or less; and
- 2. Rated for a peak current of 500 A or more.
- c.Modules or assemblies with a fast switching function having all of the following characteristics:
- 1. Anode peak voltage rating greater than 2 kV;
- 2. Anode peak current rating of 500 A or more; and
- 3. Turn-on time of 1 µs or less.
Control Reasons
Items controlled for nuclear nonproliferation reasons.
Items controlled for anti-terrorism reasons. Most items on the CCL have AT controls.
