50A Generator Diod / Bridge Diod 4 Leg (QL-50A 1200V) Big size Code: 80403190

The QL50A 1200V is a single-phase diode bridge rectifier designed to convert alternating current (AC) into direct current (DC). It handles an output direct current of up to 50A and a repetitive peak reverse voltage rating of 1200V, packaged in a metal aluminum case for thermal dissipation.

📌 Core Specifications

• Type:Single-phase bridge rectifier (4-pin configuration: two AC inputs marked with ~, one positive output +, one negative output –)
• Max Output Direct Current :50 A
• Repetitive Peak Reverse Voltage :1200 V
• Forward Voltage Drop ≤ 1.40 V per element
• Dimensions:Approximately 60 × 32 × 25 mm (varies slightly by manufacturer layout)
• Weight:~47 g

💡 Features & Applications

• Construction:Encased in an electrically insulated metal/aluminum shell providing high thermal conductivity and physical ruggedness.
• Common Uses:Industrial automation control, DC motor power supplies, battery chargers, machine tool power input rectifiers, and power converters.
• Thermal Note:Requires proper mounting or a supplemental heat sink when running near the maximum 50A capacity limit to prevent thermal runaway.
