5STP33L2800MDKIT ABB Phase Control Thyristor 2800V 200A

Product Overview

The 5STP33L2800MDKIT is a phase control thyristor (SCR) from ABB, designed for high-power rectification and motor control applications. With a rated voltage of 2800 V and current of 200 A, it delivers robust performance in industrial power electronics. Surge current capability of 3500 A ensures reliable operation under fault conditions. Weight: 1.2 kg (2.65 lbs).

Technical Configuration

Phase Control Thyristor – High Voltage

This SCR is optimized for phase control applications including AC motor drives, DC motor drives, and power converters. The 2800 V blocking voltage suits medium-voltage industrial systems requiring reliable switching and conduction.

Screw Mount – Press-Pack Design

Screw mount configuration ensures secure mechanical attachment and optimal thermal transfer to heatsinks. The press-pack design provides low thermal resistance (0.65 °C/W) for efficient heat dissipation in high-power applications.

Technical Specifications

Installation & Maintenance

Mounting

Secure the thyristor to a heatsink using the screw mount. Apply thermal compound evenly between the device base and heatsink surface. Torque mounting screws to manufacturer specifications for optimal thermal contact.

Gate Drive

Apply gate trigger current of minimum 30 mA for reliable turn-on. Gate drive circuit should provide adequate current and voltage margins for consistent triggering across the -40°C to +125°C operating range.

Protection

Use snubber circuits to protect against dv/dt and di/dt stresses. The 3500 A surge capability provides margin for temporary overloads, but proper fusing is recommended for fault protection.

Engineering Advantages

High Voltage Handling

2800 V blocking voltage enables use in medium-voltage power conversion systems. Suitable for industrial rectifiers, inverters, and AC/DC motor drives requiring high-voltage switching.

Robust Surge Protection

3500 A surge current capability protects against short-term overloads and fault conditions. This ensures system reliability and extends device lifetime in demanding industrial environments.

Wide Temperature Range

Operates from -40°C to +125°C, supporting extreme environments. Low thermal resistance (0.65 °C/W) allows efficient cooling with standard heatsink designs.

Technical FAQs

Q1: What is the maximum surge current this thyristor can handle?
