27 V Zener — clamping and regulation baseline
The RKZ27TWAJQE#H1 is a Zener diode from the RKZ27T series, specified at a nominal 27 V with a 9.18% tolerance. That tolerance band — roughly 24.5 V to 29.5 V — sets the practical regulation window for a shunt regulator or the clamping threshold in a protection circuit. For a 27 V rail, the 9.18% figure means the Zener voltage can land anywhere inside that range; if tighter regulation is needed, a lower-tolerance Zener or a precision reference is the next step.
The product status is listed as Active.
