Frequently Asked Questions
What is the gate trigger requirement for GDT100A16?
GDT100A16 has the following gate trigger characteristics: (1) Gate trigger current IGT = 100mA maximum at VGT = 1.5V. (2) Gate trigger voltage VGT = 1.5V maximum. (3) Gate non-trigger voltage VGD = 0.2V minimum to prevent false triggering. (4) Holding current IH = 100mA typical. The gate drive circuit should provide at least 150mA gate current with fast rise time (<1μs) for reliable triggering. For phase-control applications, the gate pulse should be properly synchronized with the AC line and have adequate width (typically 20-100μs) to ensure latching.
Contact our FAE team for gate drive circuit design and firing angle control.
What is the thermal resistance of GDT100A16?
GDT100A16 in 34mm package has the following thermal characteristics: (1) Junction-to-case thermal resistance RthJC = 0.5K/W. (2) Maximum junction temperature Tj(max) = 125°C (lower than diodes due to thyristor characteristics). (3) Recommended operating junction temperature Tj(op) = -40°C to +100°C. For continuous operation at 100A with 1.05V VF, the conduction loss is 105W, requiring a heatsink with thermal resistance of approximately 0.3K/W or better to maintain junction temperature below 100°C at 40°C ambient. Forced air cooling is typically required for continuous operation at full current.
Contact our FAE team for thermal simulation and heatsink selection guidance.
Can GDT100A16 be used for motor soft starter applications?
Yes, GDT100A16 is ideal for motor soft starter applications. Its characteristics make it perfect for this application: (1) 1600V rating provides adequate margin for 380-480VAC motor applications with voltage transients. (2) 100A current rating supports motors up to 50-75kW. (3) Phase-control capability enables smooth voltage ramping during startup. (4) High surge current capability withstands motor inrush currents (5-7x FLA). (5) High dv/dt capability prevents false triggering from motor voltage transients. (6) Rugged 34mm package withstands industrial environment. Soft starters reduce mechanical stress and extend motor life.
Contact our FAE team for soft starter design support and control algorithm recommendations.
What is the dv/dt capability of GDT100A16?
GDT100A16 has high dv/dt capability for reliable operation in industrial environments: (1) Critical rate of rise of off-state voltage (dv/dt)c = 1000V/μs minimum at rated junction temperature. (2) This high dv/dt capability prevents false triggering from rapid voltage transients. (3) For applications with higher dv/dt, snubber circuits may be required to limit the rate of voltage rise. (4) The high dv/dt rating is achieved through advanced chip design and optimized gate structure. This makes GDT100A16 suitable for applications with high line transients such as motor drives and power controllers.
Contact our FAE team for dv/dt analysis and snubber circuit design if needed.
How does GDT100A16 compare to GDR200A12 for rectification?
GDT100A16 (thyristor) and GDR200A12 (diode) serve different rectification needs: (1) GDT100A16 provides phase-controlled rectification with adjustable output voltage (0-100% of maximum). Requires gate control circuit but enables soft-start and voltage regulation. (2) GDR200A12 provides uncontrolled rectification with fixed output voltage. Simpler but no voltage control. GDT100A16 has higher forward voltage (1.05V vs 0.85V) and lower current rating (100A vs 200A). Thyristors are preferred when voltage control is needed; diodes are preferred for simple, high-efficiency rectification.
Contact our FAE team for thyristor vs diode selection based on your control requirements.
What commutation considerations are needed for GDT100A16?
GDT100A16 requires proper commutation for reliable turn-off in AC applications: (1) The thyristor turns off when anode current falls below holding current (IH = 100mA). (2) A minimum commutation time (turn-off time tq = 100μs) is required before forward voltage can be reapplied. (3) For line-commutated applications (50/60Hz), natural commutation from AC line is sufficient. (4) For inverter applications, forced commutation or load commutation is required. (5) Snubber circuits may be needed to limit reapplied dv/dt during commutation. Starpower provides commutation guidelines for various application topologies.
