Surge ratings and clamp voltage
The 1.5KE160A A0G: The 136 V reverse standoff voltage means the device stays non-conducting on a nominal 136 V rail, while the 152 V minimum breakdown voltage defines the point where avalanche conduction begins — a 16 V guard band between standoff and breakdown that accommodates normal rail transients without nuisance triggering.
Through-hole DO-201 axial package
Housed in a DO-201AA / DO-27 axial-leaded package (supplier device package DO-201), the 1.5KE160A A0G is a through-hole part intended for wave-solder assembly or hand-insertion into plated-through holes on a PCB. The junction temperature range spans -55°C to 175°C, covering industrial and some automotive under-hood environments — the upper limit accommodates self-heating during repetitive surge events.
General-purpose signal and DC rail protection
Marked as General Purpose in application scope and with Power Line Protection flagged as No, this TVS is suited for protecting DC power rails, signal lines, and low-voltage bus interfaces rather than direct AC mains or high-energy power-line suppression. As a single unidirectional channel (one anode-cathode pair), it clamps positive overvoltage transients referenced to ground; for bidirectional protection on AC-coupled or bipolar rails, two devices back-to-back are needed.
