1.5 kW Zener TVS for general-purpose transient clamping
The 1.5KE16A-B: It clamps transients from a 13.6 V reverse standoff to 22.5 V maximum, handling a peak pulse current of 67 A. The DO-201AA / DO-27 axial package suits through-hole board layouts where a robust transient suppressor is needed on a DC rail or signal line.
Voltage and clamping parameters
The reverse standoff voltage is 13.6 V typical, meaning the diode does not conduct appreciably below that level. This gives a 65 % clamping ratio relative to standoff, typical for a Zener-based TVS. The device is not rated for power-line protection — it is intended for secondary-side DC bus or signal-line transient suppression.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the 1.5KE16A-B as obsolete. For a new design, consider a current-production Zener TVS in the same DO-201 package from the same or alternate supplier.
