1. Product Overview

️· Product: Silicon Bridge Rectifiers
️· Series: KBL (00 to 10) - Likely indicating different voltage/current ratings within the product line.
️· Manufacturer: Diotec Electronics Corp.
️· Data Sheet Number: BKBL-400-2C
️· Key Features: These are 4 Amp bridge rectifiers.

2. Electrical Characteristics (Ratings & Specifications)

The following outlines key electrical ratings. Exact values will depend on the specific KBL model (00-10). The sheet implies they are all very similar but there are variations.

️· Maximum Repetitive Peak Reverse Voltage (Vrrm/Vrm): Likely 400V (though the data sheet doesn't explicitly state a single value - it's implied.)
️· Average Forward Current (Io): 4 Amps
️· Non-Repetitive Peak Forward Current (Ifsm): This is a surge current rating, likely high (see Figure 2). The exact value depends on cooling conditions.
️· Maximum Junction Temperature (Tj): The data sheet suggests values up to 150°C.
️· Storage Temperature Range (Tstg): -55°C to +150°C
️· Minimum Insulation Breakdown Voltage: 2500 Volts (Circuit to Case)
️· Junction Capacitance (Cj): Figure 5 shows this is a function of reverse voltage (likely ~30-50pF).

3. Key Figures & Curves (Summarized)

️· Figure 1: Forward Current Derating Curve: This is crucial. It shows how the allowable forward current decreases as the ambient temperature increases. Good heat sinking is required to maintain rated current at higher temperatures.
️· Figure 2: Maximum Non-Repetitive Surge Current: Shows the maximum surge current the rectifier can handle for a short duration, depending on pulse width and frequency.
️· Figure 3: Typical Forward Characteristic Per Diode: A standard graph of voltage vs. current for a single diode within the bridge.
️· Figure 4: Typical Reverse Characteristics: Graph of reverse voltage vs. reverse current.
️· Figure 5: Typical Junction Capacitance Per Diode: Shows capacitance as a function of reverse voltage.

4. Notes

️· Note 1: The rectifier is mounted on an aluminum plate (3.0" x 0.11") for heat dissipation. This mounting method is critical for performance.
️· Note 2: Figure 2 specifies T = 150°C.
️· Note 3: Specifies parameters for a particular surge current test.
️· Note 4: Specifies parameters for a capacitance measurement.

5. Organization and Formatting

️· The document is very dense and not perfectly organized.
️· It relies heavily on figures, which are essential for understanding the electrical behavior.
️· Table headers are not entirely consistent, making it slightly difficult to extract precise numerical values.
