A B1201UA4LTP is a bipolar transil device, which combines several technologies – strong Voltage Suppression, low capacitance, and fast response. It is a member of the Transil family from STMicroelectronics, and it is designed for the protection of vulnerable components in a wide range of electronic systems.

The B1201UA4LTP, as the name implies, is a mixed technology device. It utilizes a high voltage diode together with a Transil avalanche diode to protect against surges in a voltage range from 10V up to 400V. This makes it suitable for both commercial and automotive applications. The device also features a low capacitance (<0.5pF), fast response (typically less than 10ns), a peak pulse power (1000W), and a wide operating temperature range (-40°C to +125°C).

The working principle behind the B1201UA4LTP is relatively straightforward. When exposed to transient voltage, the avalanche diode conducts the current and diverts it away from the protected component. The diode then quickly clamps the voltage to the specified breakdown voltage, thus providing protection. The high voltage diode helps to further protect the device by limiting the current during protection. Additionally, the low capacitance ensures that the device does not interfere with system performance.

The B1201UA4LTP is ideally suited for use in a range of applications, including telecom equipment, industrial electronics, measuring systems, wireless communications, USB protection, and medical electronics systems. Its wide voltage range and low capacitance make the B1201UA4LTP suitable for use in a variety of operating environments, and its fast response time ensures that the device is capable of protecting against surges quickly and effectively.

The B1201UA4LTP is an excellent example of the advanced mixed technology protection devices that are currently available. By combining conventional technologies with innovative designs, these devices provide an excellent level of protection against transient voltage. As such, the B1201UA4LTP is an ideal choice for a wide range of applications, providing effective and reliable protection from power surges.
