TVS diodes are widely used in the protection of electronic circuits, and they can effectively prevent them from being damaged by transient voltages. 15KPA160A-HR is a kind of transient-voltage-suppression (TVS) diode. This article will discuss its application field and working principles.

Application Field of 15KPA160A-HR

The 15KPA160A-HR is mainly used for low-to-medium-power transient voltage protection for applications under IEC 61000-4-2, which is the international standard for surge immunity testing. This includes automotive, datacom, telecom, and consumer-electronics applications, such as Thunderbolt ports, lighting, power adapters, and USB ports. The device can also be used to protect unit loads, such as CPUs, RAM, and flash memories, from over-voltage surges.

In addition, this device can be used to protect against high-voltage transients. It is designed to protect against events such as ESD, lightning surge, and EFT pulses. Its reverse stand-off voltage (Vrwm) is 15 kV, and its clamping voltage (Vc) is 45.4 V. This makes it ideal for applications with high voltage transients that require robust and reliable protection.

Working Principle of 15KPA160A-HR

The 15KPA160A-HR employs a specially designed silicon-avalanche diode to protect sensitive electronic circuits from damage due to voltage transients. When the voltage exceeds the normal operating range, the diode conducts the excess current to ground, removing it from the circuit. This prevents the excess voltage from damaging the components of the circuit.

The device is bidirectional, so it can protect both positive and negative voltage surges. It is also integrated with a low-capacitance ESD protection diode, so it can protect the circuit from electrostatic discharges (ESD) ranges from +/-15KV to +/-8KV (airgap discharge), and +/-6KV to +/-4KV (contact discharge).

The 15KPA160A-HR is designed to offer a low response time and low clamping voltage. The device features a fast response time of 0.25ns and a low clamping voltage of 45.4V. The device also features an operating temperature range of -55°C to 150°C and a high peak pulse power rating of 500W.

In conclusion, the 15KPA160A-HR is a special kind of transient voltage protection diode. It is designed to protect sensitive electronic circuits from over-voltage surges, and from ESD discharges. It is mainly used in automotive, datacom, telecom, and consumer-electronics applications. It has a reverse stand-off voltage of 15kV, a clamping voltage of 45.4V, and a fast response time of 0.25ns. It also has a high peak pulse power rating of 500W and an operating temperature range of -55°C to 150°C.
