PGSMAJ13CAHM2G Circuit Protection

TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are commonly used in circuit protection. They are designed to protect sensitive electronics by clamping voltage transients to a safe voltage level. A typical application is to protect sensitive integrated circuits from ESD (electrostatic discharge) or electrical transients. The PGSMAJ13CAHM2G is a bi-directional transient voltage suppression diode.

PGSMAJ13CAHM2G Application Field

The PGSMAJ13CAHM2G is typically used to protect high speed data and communication lines from voltage transients. It is suitable for automotive applications, telecommunication systems, consumer electronic, computers and peripheral systems, and other high-speed data digital systems. It offers excellent protection against ESD and electrical transients due to high power handling capability and low let-through voltage. The diode is constructed with a dual anode with each anode performing a different role for ultimate protection.

PGSMAJ13CAHM2G Working Principle

The PGSMAJ13CAHM2G is a bidirectional diode which works as a clamping device. It is consists of two anodes, a dual diode, and an internal Zener diode. The dual diode is connected between the two anodes and acts a protection clamp. When an voltage transient occurs, the voltage on one of the anodes rises and the Zener diode starts to conduct. When the Zener voltage is reached, the PGSMAJ13CAHM2G will start to conduct and clamp the excessive voltage.

As a voltage clamping diode, the PGSMAJ13CAHM2G ensures a safe, uniform voltage level is applied to the protected circuit. The diode is designed to absorb transients quickly to protect the circuit from damage. Its low leakage current ensures that minimal current flows through the protected circuit even when not in protection mode.

Conclusion

The PGSMAJ13CAHM2G is a TVS – diode designed as a protection device against electrical transients and ESD. It is especially well-suited for high-speed data applications, automotive systems, and consumer electronic devices. It offers excellent protection against voltage transients and destructive surges with a low let-through voltage. By quickly absorbing transients, it prevents damage to the connected circuits.
