TE Connectivity / Deutsch BJE-80 Aerospace-Grade In-Line Diode Splice Assembly
Product Introduction
The BJE-80 is an aerospace-grade in-line diode assembly manufactured by TE Connectivity (Deutsch). It features an integrated rectifier/isolation diode and is encased in flame-retardant, aerospace-grade heat-shrinkable sealing tubing capable of withstanding extreme temperatures. This assembly is specifically designed for applications requiring unidirectional conduction, signal isolation, and relay surge protection in high-reliability wiring harnesses.

Application Scenarios
- Unidirectional conduction and reverse-polarity protection: Protects onboard circuitry and sensitive electronic components by preventing reverse polarity or back-feeding current.
- Inductive EMF suppression: Commonly used in circuits with inductive loads—such as relays and solenoid valves—to absorb reverse voltage spikes (flyback protection).
- Signal isolation: Enables unidirectional signal isolation in multi-channel control systems or complex wiring harness logic, preventing cross-circuit interference.
- Environmental sealing: Upon heating, the internal adhesive layer of the heat-shrink tubing melts to create a complete seal, providing resistance to water, moisture, and oil, as well as performance reliability at high altitudes and low pressures.
