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

The 6DI30B-050 is a dual IGBT (Insulated Gate Bipolar Transistor) module rated for 600 V collector-emitter voltage and 30 A continuous collector current, housed in an industry-standard 34 mm package with solder pin configuration. This module integrates two IGBT chips with corresponding freewheeling diodes in a half-bridge topology, typical for compact inverter designs where space and thermal management are constrained. The device employs NPT (Non-Punch-Through) or similar planar field-stop technology depending on manufacturing generation, with switching characteristics suited to motor drive frequencies up to 20 kHz typical. Bellsdo Tech Co., Ltd. positions this module for industrial power conversion applications from their Shenzhen, Guangdong base.

Key electrical parameters include a maximum junction temperature of 150 degrees Celsius, gate threshold voltage of 4.0 to 6.0 V typical, and switching losses characterised by turn-on and turn-off energy metrics under inductive load conditions. The module's thermal resistance from junction to case is typically in the range of 1.0 to 1.5 K/W for IGBT and 2.0 to 3.0 K/W for diode, standard for this package class and current rating. The solder pin terminals accommodate through-hole mounting on printed circuit boards with adequate copper area for heat spreading. The integrated fast-recovery freewheeling diode provides reverse recovery charge and time specifications that determine acceptable switching frequency and snubber requirements in hard-switched inverter legs.

Target applications include variable-frequency motor drives up to approximately 5.5 kW output, switched-mode power supplies, uninterruptible power supplies, and auxiliary power converters in renewable energy systems. The module's compact footprint relative to its current rating suits appliance and light industrial equipment where discrete component counts must be minimised. Bellsdo Tech Co., Ltd. lists flexible MOQ and references ISO and CE compliance, though no certificate numbers are provided. Buyers should confirm packaging type, whether individual or tube/reel, and whether thermal interface material or mounting hardware is included.

Bellsdo Tech Co., Ltd. is located at No.112, Nankeng North Road, Bantian, Shenzhen, 518100, Guangdong Province, China. The supplier holds an imported tier designation alongside a harbor trust tier, indicating they handle imported inventory or serve as a distributor for overseas-manufactured components rather than manufacturing the 6DI30B-050 themselves. The response rate is listed at 0.00 percent with zero average response hours, suggesting that platform-tracked communication metrics are not yet established. Buyers should initiate direct contact to assess responsiveness and technical competence before committing to orders.

The supplier profile does not disclose years in operation, factory ownership, revenue, or named clients. The Bantian area of Shenzhen is a significant electronics manufacturing and distribution hub, providing access to component supply chains and logistics infrastructure. No specific ISO certificate numbers, factory audit reports, or export licence details are stated in the listing. Buyers are advised to request business registration documents, tax records, and references from prior international transactions to establish supplier credibility independently.
