5PCS KBP307 Ridge Rectifier Power Diode 3A 700V Electronic Component

KBP307 Single-Phase Bridge Rectifier — 3A 700V, Pack of 5

The KBP307 is a single-phase silicon bridge rectifier in a compact DIP-4 (KBP) package, rated for 3A continuous forward current and 700V peak inverse voltage. It integrates four rectifier diodes in a full-wave bridge configuration, converting AC input to pulsating DC output in a single component — simplifying power supply design and reducing PCB footprint compared to discrete diode bridges.

Electrical Specifications

• Peak Inverse Voltage (VRRM): 700V
• Average Rectified Output Current (IO): 3A
• Non-Repetitive Peak Surge Current (IFSM): 80A (8.3ms half-sine)
• Forward Voltage Drop (VF): 1.1V typical at 3A
• Reverse Leakage Current (IR): 50µA max at 700V
• Operating Junction Temperature: −55°C to +150°C

KBP Series Voltage Ratings

• KBP301 — 100V
• KBP302 — 200V
• KBP304 — 400V
• KBP306 — 600V
• KBP307 — 700V (this listing)
• KBP308 — 800V
• KBP310 — 1000V

Pin Configuration (DIP-4)

• Pin 1 (AC~): AC input terminal 1
• Pin 2 (+): DC positive output
• Pin 3 (AC~): AC input terminal 2
• Pin 4 (−): DC negative output (GND)

Thermal Considerations

• Thermal resistance junction-to-case: ~5°C/W
• At full 3A load, a heatsink is recommended for continuous operation
• The DIP-4 package allows direct PCB mounting with optional heatsink clip

Typical Applications

• AC-DC power supply rectification (linear and switching)
• Motor drive input rectifier stages
• Battery charger rectification
• Welding equipment power stages
• UPS and inverter input rectifiers
• General-purpose full-wave bridge rectification

Package Contents

• 5 × KBP307 bridge rectifier diodes
