The document describes the features and characteristics of Silicon Avalanche Diodes 254 w w w. l i t t e l f u s e . c o m 400W Surface Mount Transient Voltage Supressors SMAJ series.
The document provides a comprehensive overview of the Littelfuse SMAJ Series 400W Surface Mount Transient Voltage Suppressors. Key features include RoHS compliance, low profile packaging with built-in strain relief, and excellent clamping capability suitable for surface-mounted applications to optimize board space.
Detailed technical data is provided in tables and charts covering maximum ratings, electrical specifications for various breakdown voltages (from 5V to 400V), and characteristic curves such as peak pulse power rating, transient thermal impedance, and junction capacitance. Mechanical specifications and package outline dimensions are also included.
| Peak pulse power dissipation (10/1000µs) | 400 Watts |
|---|---|
| Fast response time | typically less than 1.0ps from 0 Volts to V(BR) |
| High Temperature soldering | 250˚C/10 seconds at terminals |
Yes, the document lists 'RoHS compliant' as a key feature of the series.
The typical response time is less than 1.0ps from 0 Volts to V(BR).
