SKT 551/16E Capsule Thyristor 1600V, 550A
The SKT 551/16E is a capsule thyristor made from an international standard hermetic metal case with ceramic insulator. Ideal for controlled rectifiers, AC controllers and DC motor control.
- Hermetic metal case with ceramic insulator
- Capsule package for double sided cooling
- International standard case
- Shallow design with single sided cooling
- Off-state and reverse voltages up to 1800V
A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. The device conducts when the gate receives a current trigger, and continue to conduct while they are forward biased, acting as bistable switches.
Discrete thyristors are available as stud screw-fit types for applications requiring robustness and easy assembly, and capsule (disc) types for high power applications. Thyristors are also known as Silicon-Controlled Rectifiers (SCRs).
The SKT 551/16E is ideal for battery charging, welding and plating equipment applications.
