Automotive 80111 Diode 12V 1-Way Rectifier - PRF-50506 Switch Panel, 2 PCS

Automotive 80111 Diode 12V 1-Way Rectifier

Key features

• PLUG-AND-PLAY BACKFEED & REVERSE POLARITY PROTECTION - This 12V one way blocking diode blocks reverse current flow to prevent switch indicator false triggers, circuit crosstalk, and parasitic battery drain. Direct 80111 replacement compatible with PRF-50506 6-switch panels, featuring pre-installed 0.25-inch spade terminals on both ends-no soldering or crimping required. Clear color-coded polarity: Red end = anode input, Black end = cathode output for instant installation.
• DUAL BATTERY ISOLATION FOR 12V SYSTEMS - Install this inline 6A10 rectifier diode between alternator and auxiliary battery to charge the second battery while stopping reverse drain to the starter battery. Ideal for overland rigs, campers, marine boats, and 4x4 off-road vehicles with accessory circuits drawing 5 amps or less. Reliable one-way current isolation for low-current auxiliary setups.
• ELIMINATES ALTERNATOR FEEDBACK & GHOST RUN-ON - Perfect for classic vehicles including Jeep CJ7, 66-GTO and Ford Tractor after high-output alternator upgrades. Blocks backfeed on ignition exciter circuits to fix engine run-on when key is off. Also works for headlight modification, keeping low beams on with high beams, and isolating boat navigation & anchor lights on one switch without cross-circuit interference.
• 6A RATED 6A10 RECTIFIER DIODE WITH HEAVY-DUTY SEALING - Built with a 6A10 rectifier diode, rated 6A maximum continuous, recommended 5A daily load, 1000V reverse voltage, 400A peak surge capability. This automotive silicone diode assembly is fully sealed with transparent outer silicone sleeve and inner insulated heat-shrink tubing, resisting moisture, dust, vibration and engine bay high temperature for automotive, marine, motorcycle, ATV and emergency vehicle use.
• UNIVERSAL FIT READY FOR REAL-WORLD INSTALL - Pre-wired and factory sealed to replace bare loose diodes that need extra soldering and heat shrinking. Matches standard 1/4-inch spade connectors, compatible with PRF-50506 6-gang rocker switch panels and all 12 volt DC inline wiring. Also suitable for relay coil flyback suppression, freewheeling diode protection, trailer wiring, motorcycle LED accessory circuits, ATV light bar setups and emergency responder side marker light circuits.
