1KSMBJ33A

The 1KSMBJ33A is a transient voltage suppressor diode commonly used in electrostatic discharge (ESD) protection. These devices offer superior protection in ultra fast turn-on times and additional protection from impulse voltage transients. With high working and peak power ratings, they are ideal for protecting sensitive electronic devices from ESD electricity.

The 1KSMBJ33A is a state-of-the-art TVS diode. It provides transient pulse suppression with an ultra-fast response time at a fraction of the size of traditional TVS diodes. This compact device is designed to meet the most demanding requirements for suppressing critical circuit protection from transients that cause system malfunctions. The 1KSMBJ33A is a bidirectional device, offering ESD protection for both positive and negative charges.

The 1KSMBJ33A is commonly used in applications such as PCs, cellphone chargers, AC adapters, and other electronics that require advanced ESD protection. This device is designed to protect equipment against ESD events of 8kV for Contact and 15kV for Air-Gap Discharge, and offers peak pulse power dissipation (PPPD) up to 600W. PPPD is the transient power that the device can withstand for a single pulse, without permanent damage.

The 1KSMBJ33A works on a simple principle: when a pulse strikes the device, the power is dissipated across the junction. The power flow is diverted from semiconductor components and discharged to ground. This is known as “avalanche breakdown”, which ensures that transients are quickly and safely redirected to the ground plane away from sensitive components.

In addition, the 1KSMBJ33A is designed with a low power-response time of 2 nanoseconds, making it ideal for applications where fast response is needed to protect delicate electronic components. Extended leads make the device easy to attach to circuit boards, which is another desirable feature for protecting against ESD.

The 1KSMBJ33A is an ideal choice for protecting sensitive electronic devices from ElectroStatic Discharge. With its ultra-fast response time and high peak power dissipation, it is suitable for a wide range of applications. The device is also designed with extended leads and a small footprint, making it an easy-to-use solution for circuit protection.
