Actually i notice that the UDZV8.2B (8V2 Zener) is said in its datasheet page 2 to have a Reverse Leakage current of 500nA at VR=5V and 25degC. However, its datasheet on page 4 states that it has a Reverse Leakage current of <10 picoAmps at VR=5V and temp = 25degC.

Do you know which one is correct?

Also,

Please can you state what is the overall leakage current through these attached back to back zeners?

One is a 5V1 zener, and the other an 8V2 zener.

UDZV5.1 (5.1V Zener)

(BTW Page 4 and page 2 of their datasheets contradict each other over leakage current)
