The SanRex DFA150BA80 is an IGBT module designed for rectification applications that require the prevention of rush current. It is specifically configured with six diodes connected in a 3-phase bridge configuration and a thyristor connected in series with the DC line. Below are the maximum ratings and characteristics of this module:
- VRRM (Repetitive Peak Reverse Voltage): 800V – This is the maximum voltage the module can handle in a repetitive reverse-bias condition.
- ID (Output Current – D.C.): 150A – This is the output current rating for three-phase full-wave rectification at an operating junction temperature of 105°C.
- IFSM (Surge Forward Current): 1460A – This is the maximum surge forward current for a single cycle at 50/60Hz, with a peak value in a non-repetitive condition.
- Tj (Operating Junction Temperature): -40 to +150°C – This is the temperature range within which the module can operate safely.
- VFM (Forward Voltage Drop, maximum): 1.35V – This is the maximum forward voltage drop across the module when the forward current is 150A, measured instantaneously.
- Rth(j-c) (Thermal Impedance, maximum – Junction to Case): 0.09°C/W – This is the maximum thermal impedance from the junction to the case of the module, indicating its ability to dissipate heat.
- Tstg (Storage Temperature): -40 to +125°C – This is the temperature range within which the module can be safely stored.
- Mounting Torque (Recommended Value for Mounting): M5 screws with a recommended torque range of 1.5-2.5 N·m (kilogram-force·centimeter).
- Mounting Torque (Recommended Value for Terminals): M5 screws with a recommended torque range of 1.5-2.5 N·m (kilogram-force·centimeter).
- Rth(c-f) (Thermal Impedance, maximum – Case to Heatsink): 0.6-0.1°C/W – This is the maximum thermal impedance from the case to the heatsink, and it depends on factors like the thermal conductivity of the silicone grease and the effective rate of contact.
- VISO (Isolation Breakdown Voltage – R.M.S.): 2500V – This is the isolation breakdown voltage, indicating the module’s isolation capability from AC input to output, tested for 1 minute.
- Mass (Typical Value): 150g – This is the typical mass (weight) of the module.
