70TPS12 Description
The 70TPS12 is a high-performance transient voltage suppressor (TVS) diode to protect sensitive electronics from voltage spikes and surges. Think of it as a safety guard for your circuits—when unexpected voltage spikes like those from lightning or power surges hit, the 70TPS12 kicks in to divert the excess energy away from your devices, preventing damage.
It’s compact, reliable, and built to handle high surge currents, making it a popular choice for applications like power supplies, automotive systems, and industrial equipment.
70TPS12 Pinout
K: This is the connection to the drain terminal of the MOSFET, where the high voltage or current flows out of the device.
A: This is the gate terminal, which controls the on/off state of the MOSFET. Applying voltage here switches the MOSFET on or off.
G: This is the source terminal, which is where the current enters the MOSFET.

How to Use 70TPS12?
To use the 70TPS12 MOSFET, first connect the K pin to the high-voltage side of your circuit or the load. This is where current will flow out of the device when the MOSFET is on. Next, connect the G pin to the negative side of the circuit or ground, which serves as the current entry point. Finally, apply a voltage to the A pin to control the MOSFET's state.
When a voltage is applied to the Gate (A), it switches the MOSFET on, allowing current to flow from the Source (G) through to the Drain (K). To turn the MOSFET off, remove the voltage from the Gate (A), which will stop current flow between Source (G) and Drain (K).
In this way, the 70TPS12 acts as a switch, with the Gate (A) controlling whether the current flows between the Drain (K) and Source (G), depending on whether the device is on or off.
