back diode การใช้

• Rx signal goes through a device consisting of 2 back-to-back diodes providing protection for the receiver's front end.
• In semiconductor devices, a "'backward diode "'( also called "'back diode "') is a variation on a Zener diode or tunnel diode having a better conduction for small reverse biases ( for example  0.1 to  0.6 V ) than for forward bias voltages.
