Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If metal oxide varistor construction
Varistors use different materials and mechanism than semiconductor Zeners.
If Zener parts or unmounted chips
Die/chips without leads classified as parts of semiconductor devices.
If communications apparatus parts
Specified machine parts supersede general semiconductor classification.

Import Tips & Compliance
• TVS diodes classified as Zener if semiconductor junction-based; provide I-V curves
• High volume electronics; consider bonded warehouse for duty deferral
• Common misclassification as varistors (8535.40); verify avalanche vs varistor operation
