Transient suppression for 94V rails
The 1.5KE110C-B: This means a 94 V bus sees the diode remain high-impedance until the transient pushes past 99 V, at which point the device shunts current and clamps the spike below 160 V — safe for downstream semiconductors rated at 200 V or higher.
Package and thermal envelope
Housed in a DO-201AA (DO-27) axial leaded package, with the supplier device package designated DO-201. The through-hole mounting allows the body to be soldered into a PCB or point-to-point wired — the axial leads carry the surge current into the junction with minimal inductance. The 175°C ceiling means the device can absorb repetitive pulses in a hot enclosure without derating the peak pulse power — the limiting factor becomes the average power dissipation, not the single-pulse capability.
Obsolete — sourcing through independent channels
Littelfuse lists the 1.5KE110C-B as obsolete. No official successor is recorded — the 1.5KE series has been superseded by newer TVS families with similar voltage ratings but different package options or higher surge capability. For BOM lines that still call out this specific order code, the part is available through independent surplus and broker channels. Each lot is verified for authenticity and tested to the original datasheet parameters before shipment.
