2. Product type

Type: High-power thyristor (Thyristor), a silicon-controlled rectifier device, used for switching control of high-voltage and high-current circuits.

2. Core technical parameters (5SDF1045H0002)

1. Electrical parameters

Reverse repetitive peak voltage (VRRM): 4500V (can withstand instantaneous reverse high voltage, suitable for high-voltage DC system).

Forward average current (IF (AVM)): 1000A (average current when continuously turned on, requires cooling system).

On-state peak voltage (VTM): ≤1.7V (voltage loss in the on state, the lower the higher the efficiency).

Switching loss: conduction loss and turn-off loss are optimized, suitable for high-frequency switching scenarios (such as frequency converters, inverters).

di/dt tolerance: ≥500A/μs (current change rate tolerance, avoid commutation failure).

2. Physical and mechanical characteristics

Package size: diameter of about 68mm (in line with ABB standard 68mm thyristor package), height of about 50mm, weight of about 2.5kg.

Installation method: Bolt fixing, 16-20kN installation force is required (ensure close contact with the heat sink to avoid overheating).

Shell material: Metal ceramic package, protection level IP20 (indoor use), vibration resistance (10-500Hz, 20g).

Temperature range:

Operating junction temperature (Tj): -40℃~+125℃;

Storage temperature: -55℃~+150℃.

3. Special performance

Cosmic radiation tolerance: With high-level radiation resistance (such as LEO low earth orbit application scenarios), suitable for industrial equipment of aerospace derivative technology.

Bufferless design: Optimize switching characteristics, can be directly used in bufferless circuits, and simplify system design.

Built-in protection: Some models contain temperature sensors and support thermal protection alarms (need to cooperate with drive circuits).
