TVS (Transient Voltage Suppressor) diode or Transil diode is a semiconductor protection device designed to protect sensitive electronics components in case of unexpected voltage spikes or transients. These transient voltages are most commonly created by contact with a load or caused by the switching of a large inductive load. TVS-diodes comes in various types and sizes, ranging from small general-purpose units to large multi-chip arrays. This article will focus on one of these arrays, the 5KP58HE3/73.

The 5KP58HE3/73 is a discrete TVS array from Semtech Corporation, consisting of four channels with an operating voltage range from 5 to 58 Volts. The 5KP58HE3/73 has a peak pulse power rating of 500 watts per line (2KW total) and an IEC-rated transient protection of 6000 Amperes (IEC61000-4-2). This device is designed with both common and separate mode application support, allowing for greater flexibility of use.

The 5KP58HE3/73 has many applications such as power line protection, automotive protection, medical power, computer systems, DC/DC converters and more. This device is also ideal for use in applications requiring high-speed switching, such as pulse generators and digital signal processors (DSPs).

The 5KP58HE3/73 is designed with a series of diodes connected in series with a common cathode pin. The design allows it to perform very fast, clamping any transient voltage within a few nanoseconds. This makes it effectively a bidirectional protectors, protecting both from voltage surges coming from outside the device, as well as to protect other connected devices from the energy of internal voltage surges. The device also features a high degree of ESD protection (up to 16KV) and is designed to continually monitor the voltage conditions on the line for a fast reaction against transients.

The 5KP58HE3/73 is an ideal product for applications that require high power transient protection with high speed response times. Its high power rating and fast responding time makes it well suited for applications such as power line protection, automotive protection, medical power, DSPs and more. This device can be used in both common and separate mode applications due to its design, and is designed with a high degree of ESD protection (up to 16KV), which makes it an ideal product for use in harsh environments.
