SMAJ26A-TR 26V Unidirectional TVS Diode (400W, SMA/DO-214AC)

Protect your 24V DC power rails and high-voltage battery systems from destructive inductive transients with the SMAJ26A-TR Transient Voltage Suppressor (TVS) diode. When working with 24V industrial systems, 6S LiPo battery packs (fully charged at 25.2V), or high-torque DC motors, sudden voltage spikes caused by inductive kickback can instantly destroy sensitive microcontrollers and MOSFETs. Featuring a reverse standoff voltage ($V_{RWM}$) of 26V and a tight breakdown voltage ($V_{BR}$) window of 28.9V to 30.4V, this diode remains completely transparent during maximum standard operating voltages while ensuring fast, precise clamping the moment a surge occurs.

Capable of absorbing up to 400 Watts of peak pulse power, it shunts dangerous transient energy safely to ground. Housed in the industry-standard SMA (DO-214AC) surface-mount package, it provides excellent thermal handling in a compact footprint. It is an ideal protective element for custom drone power distribution boards (PDBs), 24V 3D printer motherboards, and industrial automation control systems.

Key Features:

• Optimized 26V Standoff Voltage ($V_{RWM}$): Ideal safety margin for 24V DC power rails and 6S LiPo setups (25.2V max) without triggering under normal supply variations.

• Precise Breakdown Range ($V_{BR}$): Triggers reliably between 28.9V and 30.4V for fast and accurate overvoltage response.

• 400W Peak Pulse Power: Effectively absorbs heavy voltage transients and inductive kickback from motors and solenoids.

• Standard SMA Footprint: Compact DO-214AA surface-mount package allows easy hand soldering and automated assembly.
