Import 6di30b-050a — Buy in Bulk from Supplier in China

The 6DI30B-050A is an IGBT module rated for 30 A collector current and 500 V collector-emitter voltage, designed for hard-switching inverter and motor drive applications. It integrates a half-bridge configuration with built-in fast-recovery freewheeling diodes, reducing external component count and simplifying gate drive layout. The module utilises a standard 34 mm baseplate with isolated copper base for direct heatsink mounting, typical of industrial IGBT packages in this voltage class. Bellsdo Tech Co., Ltd. sources this component from its Shenzhen facility in Guangdong Province, though buyers should confirm whether units are original manufacturer or compatible aftermarket production.

Construction centres on a DBC (direct bonded copper) substrate that provides both thermal conductivity and electrical isolation between the silicon die and the mounting surface. The chip technology is a field-stop trench IGBT, a standard design for 600 V-class devices that balances conduction loss against switching energy. Typical thermal resistance from junction to case is in the range of 0.65 K/W per switch, though buyers should request the specific Rth(j-c) value from Bellsdo Tech for lot verification. The module is housed in a plastic casing with solderable or screw terminals, depending on production batch, with torque specifications for the latter typically 0.8 to 1.2 Nm.

Primary applications include variable-frequency motor drives up to approximately 5.5 kW, switched-mode power supplies, and uninterrupted power supply inverters. Renewable energy installers and industrial automation integrators are the core buyer segments. Trade terms from this supplier require direct confirmation, as no MOQ, lead time, or Incoterm is stated in the available data. Buyers should also verify whether Bellsdo Tech holds inventory in Shenzhen or arranges factory shipment, and whether technical documentation includes full safe operating area curves and transient thermal impedance data.

Bellsdo Tech Co., Ltd. maintains its registered address at No.112, Nankeng North Road, Bantian, Shenzhen 518100, Guangdong, China. The company is classified as an imported-tier supplier on the platform, with harbour trust tier status. The response rate is recorded at 0.00 percent, with an average response time of zero hours, indicating no inquiry response data is available through the platform. Buyers should treat direct email or telephone contact as the primary communication channel, and verify responsiveness before placing orders.

The supplier profile does not disclose manufacturing ownership, factory certifications, or in-house test capabilities. No information is provided on year of establishment, employee count, annual revenue, or named clients. The listing presents Bellsdo Tech as a source for the 6DI30B-050A IGBT module, but does not clarify whether the company is an authorised distributor, a broker, or a manufacturer of compatible replacements. Buyers should request supplier qualification documents, including any ISO or CE certification scope, and confirm whether warranty and technical support are provided by Bellsdo Tech or passed through to the original component manufacturer.
