Tianjin Century Electronics Co., Ltd supplies silicon rectifier diodes, Schottky barrier diodes, and Zener voltage regulator diodes, with specific mention of the 1N4007 as a key product. The 1N4007 variant has a 1000 V reverse voltage rating and 1 A forward current capacity, consistent with standard industrial rectifiers. The supplier emphasizes fast recovery diodes for high-frequency applications, indicating a focus on switching performance beyond basic rectification.
The diodes are manufactured using silicon semiconductor material with controlled diffusion profiles to achieve low forward voltage drop and high thermal stability. Schottky variants are implied to have lower forward voltage than standard PN junctions, typically around 0.3 V to 0.5 V, though exact values are not provided. Packages include both through-hole and surface-mount types, with the 1N4007 likely in DO-41 housing. No formal certification claims are substantiated with documentation.
These components are sourced by manufacturers of power converters, automotive ECUs, and renewable energy inverters. Buyers typically require volumes from 10,000 units per order for cost-effective shipping. Trade terms include FOB and CIF options, with packaging designed for international transit. Lead time is not specified, and minimum order quantity is not stated. Buyers must confirm exact packaging format and delivery schedule directly with the supplier.
| Semiconductor Material | Silicon (Si) |
| Diode Types Supplied | Silicon rectifier, Schottky barrier, Zener voltage regulator |
| Forward Voltage Drop (1N4007) | 1.1 V maximum at 1 A (standard for silicon rectifier diodes) |
| Maximum Reverse Voltage (1N4007) | 1000 V |
| Package Types | Through-hole (DO-41) and surface-mount (SOD-123, SMA) - typical for modern applications |
| Typical Forward Current | 1 A for rectifier diodes, 200 mA to 1 A for Zener and Schottky variants |
| Reverse Recovery Time | Typical 25 microseconds for rectifiers, less than 10 ns for Schottky diodes (industry standard) |
| Junction Temperature Range | -55°C to +150°C (standard operating range for silicon diodes) |
| Thermal Resistance (RθJA) | Typical 100°C/W for DO-41 package (standard for through-hole diodes) |
| Zener Voltage Range | Typical 3.3 V to 200 V (standard for general-purpose Zener diodes) |
Tianjin Century Electronics Co., Ltd is a company based in Tianjin, China, with a registered office in Times Apartment. The listing shows harbor trust tier and no response rate, indicating verified business registration but limited buyer interaction. No information is provided about company size, production facilities, years in operation, or in-house manufacturing capability. The supplier appears to function as a distributor or aggregating trader rather than a producer.
The supplier references specific diode types (1N4007, Schottky, Zener) and package formats, suggesting familiarity with component specifications. However, no certifications, test reports, or quality control processes are mentioned. Buyers should treat this as a sourcing agent and request product samples, test data, and batch traceability before committing to large orders. The absence of response metrics suggests communication may be slow or inconsistent.
EximNext supplies a comprehensive range of semiconductor diodes including silicon rectifier diodes, Schottky barrier diodes, and Zener voltage regulator diodes. These components are essential for power supply rectification, signal clamping, and overvoltage protection across industrial electronics, automotive, and consumer device manufacturing. Available in through-hole and surface-mount packages, our diodes meet international quality standards and are competitively priced for global import and export trade.

Sourcing Diode from Tianjin Century Electronics Co., Ltd - China Import Guide
Verify the exact part number and package type before ordering, as the supplier lists multiple diode types. Request test reports for forward voltage, reverse leakage, and surge current on the specific batch. Do not assume '1N4007' means identical performance across suppliers - manufacturing variations exist. Confirm that markings are laser-etched and legible, and that packaging includes anti-static protection for SMD components.
Confirm Incoterms and lead time directly with the supplier, as neither is stated. FOB Tianjin or CIF destination are likely, but shipping terms must be documented. Payment terms are not specified; standard practice is 30% deposit with balance against bill of lading. Allow 30 to 50 days for production and export processing. Ensure the supplier provides a commercial invoice with HS code 8541.10 for customs clearance.
Perform incoming inspection using a curve tracer to validate forward voltage and reverse breakdown characteristics. Sample 5% of the batch for thermal cycling between -40°C and 125°C. Check for solderability on leads and surface-mount pads. Request a Certificate of Analysis with test results for key parameters. Retain samples for 12 months to support warranty claims. Reject any batch without traceable lot numbers or inconsistent electrical performance.
