What are the key features of SMAJ26A-13-F?

400 W peak pulse power dissipation for robust transient overvoltage protection on 26 V rails
Tight clamping voltage window of 30.4 V nominal to 42.1 V maximum limits stress on protected devices
SMA package provides low inductance surface-mount placement for fast ESD response time

What is SMAJ26A-13-F used for?

The SMAJ26A-13-F is used to protect input lines of automotive sensors, industrial I/O interfaces, and communication bus drivers operating on 24 V or 26 V rails from ESD strikes and lightning-induced transients. Its 400 W peak power rating handles 8/20 µs surge pulses in compliance with IEC 61000-4-5 Level 3 environments. It is also deployed on RS-485, CAN bus, and analog sensor input protection circuits requiring clamping below 42.1 V.

Frequently Asked Questions

What standoff and clamping voltages does SMAJ26A-13-F provide for overvoltage protection?

The SMAJ26A-13-F has a 26 V standoff voltage, a nominal breakdown voltage of 30.4 V, and a maximum clamping voltage of 42.1 V at peak pulse current. This tight clamp window protects devices on 24 V to 26 V rails from transients exceeding the supply voltage without false triggering during normal operation.

How much peak transient power can SMAJ26A-13-F absorb in an industrial ESD event?

SMAJ26A-13-F absorbs 400 W of peak pulse power during a 10/1000 µs transient, meeting IEC 61000-4-5 surge immunity requirements. This rating allows the device to protect 26 V sensor and I/O lines exposed to conducted transients on industrial field cables of 10 m or longer.

Is SMAJ26A-13-F suitable for CAN bus or RS-485 transceiver protection on automotive platforms?

Yes, SMAJ26A-13-F works well on CAN bus and RS-485 bus protection lines in automotive and industrial systems. Its SMA package mounts close to transceiver pins, its 42.1 V maximum clamp protects 3.3 V and 5 V logic transceivers behind signal conditioning resistors, and the 400 W rating handles load dump pulses common in 24 V vehicle environments.

Does SMAJ26A-13-F comply with RoHS for modern product designs?

The SMAJ26A-13-F is listed as Pb-free No, meaning it uses a tin-lead solder finish. Designers targeting RoHS-compliant products should check for an available lead-free alternative within the SMAJ series or confirm with Diodes Inc. whether a compliant variant in the SMA package covers the 26 V, 400 W specification.
