What are bidirectional Zener diodes used for in DC transient protection?

I often see two zeners (in opposition to each other) being placed across the power supply rails. I don't understand why that is necessary. For example, if I have a 16V Zener diode and a 12V power rail, the 16V Zener will protect the supply from…

Are transient suppression diodes necessary for a battery powered system?

I've seen on designs where there is a TVS transient suppression diode on the voltage supply. For example, when the voltage supply is say a wall plug. However, are such diodes really necessary in a battery powered system? I can't think of any way…

TVS specification understanding

I have some questions regarding Transient Voltage Suppressors (TVS). The specific datasheet I'm referring to is this, from 1SMB22AT3G. Here is some of its specs: \$V = 22V\$ \$V_c = 35.5V\$ \$I_{pp} = 16.9A\$ \$tp = 10us\$ (protection pulse…

Spark Suppressor Question

I built a timer for my water heater and have a question about spark suppression. I am using a 120v house timer 1875W to operate a Packard (240B) 2 pole 40A 120v coil relay. The output of the relay contacts are connected to 240v that goes to the…
