I. Basic product information

1. Model correspondence

3BHL000396P0001: It may be the material code (P/N, Part Number) of the diode within ABB, used for inventory management and order identification.

5SDF0460F0001: It is the standard model of the product, usually containing core technical parameter information.

2. Product type

Type: Avalanche diode (Avalanche Diode), a power semiconductor device, is commonly used in overvoltage protection of high-voltage circuits, switching power supplies or industrial drive systems.

II. Core parameter analysis (5SDF0460F0001)

1. Electrical parameters

Rated voltage (VRRM): From the model "0460", the reverse repetitive peak voltage is about 4600V (some information may be marked as 6kV, please refer to the official manual).

Rated current (IF): average forward current is about 400A ("04" in the model may represent 400A level, please refer to the specification).

Turn-off voltage (VDRM): typical value ≥4600V, used to suppress transient overvoltage in high-voltage circuits.

Power loss: low conduction loss and switching loss, suitable for high-frequency switching scenarios (such as inverters, inverters).

2. Physical characteristics

Package size: diameter is about 68mm (in line with the "68MM" logo), height is about 30-50mm depending on the package type, and weight is about 1-2kg.

Package material: metal shell (such as copper or aluminum), enhanced heat dissipation performance, protection level is usually IP20 (indoor use).

Installation method: bolt fixing, need to be used with a heat sink, installation force recommended 10-15kN (to avoid overheating due to poor contact).

3. Performance characteristics

Avalanche characteristics: With high voltage resistance and fast shutdown capabilities, it can release energy through avalanche breakdown when overvoltage occurs, protecting the circuit from damage.
