Within the field of TVS – Diodes, the MASMBJ24A is a transient voltage suppressor/suppression diode that aids in protecting vulnerable electronic circuits from momentary overvoltage events. The device is a bidirectional, miniature, lightweight unit with a 200W power peak pulse power (ppp) rating. This article will focus on the applications and working principle of the MASMBJ24A.

Applications

By its nature, the MASMBJ24A TVS-Diode is suited for protecting vulnerable circuits from high power surge events such as those created by electrostatic discharges. It is also ideal for prevention of electrical transience from power lines that can lead to unexpected system reset. The maximum peak pulse power (PPP) rating for the device is 200Ws, meaning it is suitable for circuits under 10A of current. The device is characterized as a bidirectional protector, meaning it will react to transient events from either direction – positive or negative.

The MASMBJ24A is CEC VP4 certified, which is a standard set by the California Energy Commission (CEC) for devices that protect their host application from transient voltage events. This makes it particularly suitable for applications where a high level of safety is required such as automotive, medical, mobile and industrial fields.

Operating Principles and Properties.

The MASMBJ24A TVS-Diode operates by clamping any incoming voltage above a certain threshold. It can be activated with reverse or forward current, and holds a reverse breakdown voltage of 5.8V. The device also has a defined response time of 10ns, meaning it will react and protect your circuit within 10 nanoseconds of an incoming disturbance. The suppression level for the device is 600W, and the clamping voltage (VC) for a 10/1000uA pulse is 7.7V.

The device operates on a common cathode configuration, and the temperature range for it is -55°C to +150°C, making it highly suitable for extreme environments. The device also has a very low leakage current of 200uA @ 5.8V. In addition to this the device has a power derating curve of 6.7mW/°C.

Conclusion

The MASMBJ24A is a solid-state TVS-Diode that provides short-circuit protection and transient voltage suppression for vulnerable electronic circuits. Its low leakage current, low capacitance, and low clamping voltage make it ideal for a range of applications from automotive to industrial. Furthermore, its CEC VP4 certification makes it a perfect choice for applications where safety and reliability is paramount.
