SMCJ28A 28V Unidirectional TVS Diode (1500W, SMC/DO-214AB)

Deploy heavy artillery to protect your 24V power systems with the SMCJ28A Transient Voltage Suppressor (TVS) diode. When building custom 24V 3D printers (like Voron or RatRig), heavy-duty CNC routers, or 6S LiPo drone power distribution boards, the back-EMF (electromotive force) generated by large stepper motors or sudden load dumps can instantly vaporize expensive motherboards. This heavy-weight unidirectional diode acts as an invincible shock absorber for your power rails.

With a standoff voltage of 28V, it provides the perfect "breathing room" for standard 24V industrial rails and fully charged 6S LiPo batteries (25.2V), remaining completely invisible during normal operation. But the moment a massive inductive spike hits, it instantly clamps the voltage, absorbing a mind-blowing 1500 Watts of surge energy. Housed in the massive SMC (DO-214AB) surface-mount package, it can dissipate massive amounts of heat, making it the ultimate fail-safe for extreme-duty DIY electronics and robotics.

Key Features:

• Massive 1500W Surge Rating: Capable of safely absorbing catastrophic inductive kickbacks from large NEMA stepper motors and heavy solenoids.

• 24V System Guardian: The 28V threshold is perfectly tailored for protecting 24V DC industrial systems and 6S LiPo setups without triggering prematurely.

• Unidirectional Clamping: Optimized for DC power supplies, neutralizing destructive positive voltage spikes while effectively blocking reverse polarity.

• Heavy-Duty SMC Package: The large DO-214AB footprint offers vastly superior thermal mass and energy dissipation compared to smaller SMA or SMB diodes.
