What the 1N6275AHE3_A/D is and how the clamping stack works
The 1N6275AHE3_A/D is a unidirectional Zener-based transient voltage suppressor (TVS) — branded by Vishay as a TransZorb® — packaged in the DO-201AA axial format for through-hole assembly. The clamping stack is what defines TVS fit: 12.8 V reverse standoff is the DC working voltage the line sits behind.
Automotive qualification and thermal margin
AEC-Q101 qualification signals the part passed the automotive discrete stress suite: humidity, temperature cycling, surge life — the kind of testing an OEM auditor requests when the part is in a safety-critical or powertrain-adjacent circuit. The through-hole lead frame and DO-201AA body conduct heat to the board more effectively than a surface-mount part, which helps hold TJ within limits under repetitive surge duty.,.
Package, mounting, and sourcing posture
Tape & Box (TB) packaging with the 1.5KE supplier device package designation means the part ships on a tape-and-reel or ammo pack suitable for automated axial insertion — verify the exact tape orientation and lead forming requirements against the Vishay datasheet before committing to a pick-and-place program, since the 1.5KE family covers multiple body sizes.,.
