Product details

Package and rework — DO-214AC SMA on the bench

The SMAJ7.5CA-13: The DO-214AC SMA body is a two-terminal surface-mount package with a single cathode band — orientation is unambiguous, and the large solderable end caps reflow reliably under hot air or IR. No exposed thermal pad means the part self-heats through the leads and board copper; the 400W rating assumes a standard FR-4 footprint with adequate trace width to sink the pulse energy. Supplied on Tape & Reel (TR), it feeds directly into pick-and-place — no manual handling required for volume assembly.

Frequently asked questions

What does the 400W peak pulse power mean for my circuit?

The 400W rating (10/1000µs waveform) means the TVS can absorb a 31A surge for 1ms before the junction temperature exceeds limits — adequate for IEC 61000-4-5 surge immunity on signal ports, but not for direct lightning strike protection without additional series impedance.

What compliance documentation does Diodes Inc provide for SMAJ7.5CA-13?

The standard Diodes Incorporated TVS family is RoHS-compliant and REACH-compliant per their product compliance documentation.
