Frequently Asked Questions
What is the gate trigger requirement for GDT200A16?
GDT200A16 has the following gate trigger characteristics: (1) Gate trigger current IGT = 150mA 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 = 150mA typical. The gate drive circuit should provide at least 200mA 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 50-150μs) to ensure latching.
Contact our FAE team for gate drive circuit design and firing angle control.
What is the thermal resistance of GDT200A16?
GDT200A16 in 62mm package has the following thermal characteristics: (1) Junction-to-case thermal resistance RthJC = 0.3K/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 200A with 1.1V VF, the conduction loss is 220W, requiring a heatsink with thermal resistance of approximately 0.2K/W or better to maintain junction temperature below 100°C at 40°C ambient. Liquid cooling or high-performance forced air cooling is typically required for continuous operation at full current.

Can GDT200A16 be used for large motor soft starter applications?
Yes, GDT200A16 is ideal for large motor soft starter applications. Its characteristics make it perfect for this demanding application: (1) 1600V rating provides adequate margin for 380-480VAC motor applications with voltage transients. (2) 200A current rating supports large motors up to 100-150kW. (3) Phase-control capability enables smooth voltage ramping during startup. (4) Ultra-high surge current capability withstands motor inrush currents (5-7x FLA). (5) Ultra-high dv/dt capability prevents false triggering from motor voltage transients. (6) Rugged 62mm package withstands industrial environment. Large soft starters reduce mechanical stress and extend motor life.

What is the dv/dt capability of GDT200A16?
GDT200A16 has ultra-high dv/dt capability for reliable operation in industrial environments: (1) Critical rate of rise of off-state voltage (dv/dt)c = 1500V/μs minimum at rated junction temperature. (2) This ultra-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 ultra-high dv/dt rating is achieved through advanced chip design and optimized gate structure. This makes GDT200A16 suitable for applications with high line transients such as large motor drives and power controllers.

How does GDT200A16 compare to GDT100A16?
GDT200A16 and GDT100A16 serve different current requirements: (1) GDT200A16 (200A, 62mm) is designed for high-power applications requiring maximum current handling. (2) GDT100A16 (100A, 34mm) is for medium-power applications. GDT200A16 has slightly higher VF (1.1V vs 1.05V) and IGT (150mA vs 100mA). The 62mm package has better thermal performance (0.3K/W vs 0.5K/W) but requires more sophisticated cooling. Selection depends on current requirements and cooling capabilities. For motors above 75kW, GDT200A16 is the recommended choice.

What commutation considerations are needed for GDT200A16?
GDT200A16 requires proper commutation for reliable turn-off in AC applications: (1) The thyristor turns off when anode current falls below holding current (IH = 150mA). (2) A minimum commutation time (turn-off time tq = 150μs) 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.
