TPC13AHM3/87A

TPC13AHM3/87A is a high-temperature, pressure-sensitive, laser-triggered, fast pulse-switching diode designed for the deployment of various TVS (transient voltage suppression) needs. It is one of the many TVS diodes that are gaining popularity across various industry sectors. This device is widely used in accelerating the reverse switching of switch-mode power supplies (SMPS), protecting against lightning- and electrical-surge threats, and suppressing common-mode values on data buses and power lines.

The TPC13AHM3/87A has a breakdown voltage range of 12-17V, with a maximum clamping voltage of 25V, a surge current of 20A (8/20 μs), and a hold current of and 18A. It has a breakdown clamping ratio of 8/20 μs, meaning that it protects by clamping the transient current in a short time and maintaining a low clamping voltage. Additionally, it is automotive-grade standard-compliant and easily scalable to accommodate SMPS power stages of up to 400W. It is also RoHS-compatible and can operate in temperatures ranges between -40 and 125°C.

In addition to its robust physical characteristics, the TPC13AHM3/87A also has a unique working principle. Instead of the standard Zener diode configuration, the TPC13AHM3/87A utilizes a doped laser-diffused avalanche breakdown. This allows it to effectively respond to both surge and common-mode noise. The laser-diffused structure of the diode effectively accelerates current-concentration and charging, ensuring fast response times. The avalanche breakdown, which allows the diode to operate at higher temperatures, helps protect the circuit from abnormally high voltage or current spikes.

These features make the TPC13AHM3/87A highly suitable for use in almost any kind of TVS design. It is particularly useful in automotive and military applications, where high-temperature and wide voltage ranges are unavoidable. With its wide voltage range, robust design, and laser-diffused structural design, the TPC13AHM3/87A is an excellent choice for any kind of TVS diode application.
