TVS - Diodes encompass a large range of devises used for electronic circuit protection. The P4SMA91CA M2G is a high voltage, low-capacitance, uni-directional transient voltage suppressor (TVS) diode array which provides bidirectional ES suppression. It offers various features including dual-channel, symmetrical clamping, quick response, low parasitic inductance, and small size. Its provided improved performance and reliability, and can effectively protect sensitive electronic components from the harmful effects of transients caused by power and signal line disturbances. Application FieldThe P4SMA91CA M2G TVS diode array is ideally suited for general electronic protection. Typical applications include protection devices for end equipment, such as PC motherboards, telecom equipment, consumer electronics, industrial equipment and automotive electronics. Working PrincipleWhen a surge or an overvoltage (from +4V to +91V) on either channel of the P4SMA91CA M2G transient voltage suppressor diode array is detected, the diode conducts the current away to the ground. This limits the voltage seen there. The diode array automatically reset itself with no further disruption to the rest of the circuit.The TVS diode array can conduct up to 5A continuous current without breakdown and has a wide operating temperature range of -55 to +150°C. Its surface mount package reduces parasitic inductance and ensures fast response to transients.The P4SMA91CA M2G also provides excellent ESD protection. It has a low parasitic capacitance which ensures high frequency protection and reduced EMI. It has an IEC-61000-4-2 six-sigma standard level plus a high consumption current.ConclusionThe P4SMA91CA M2G transient voltage suppressor diode array provides superior protection against transient overvoltages and ESD. Its low capacitance makes it ideal for high frequency protection and reduces potentially dangerous EMI. Its wide operating temperature range of -55 to +150°C and high continuous current handling capability make it suitable for various applications, including PC motherboards, telecom equipment, consumer electronics, industrial equipment and automotive electronics.
