This document describes the features and characteristics of the 500 Watt Transient Voltage Suppressors (TVSs) produced by Microsemi Scottsdale Division. These products, available in the DO-213AB size MELF package, offer the highest level of Peak Pulse Power (PPP) in the industry. They provide protection from switching transients, induced RF, secondary lightning, as well as ESD or EFT. The series includes both unidirectional and bidirectional options with C or CA suffix. The MELF package configuration prevents lead damage and reduces inductive parasitics for minimal transient voltage overshoots.
The TGL41 series from Microsemi are 500 W transient voltage suppressors in a DO‑213AB MELF package, covering standoff voltages from 6.8 V up to 200 V. Both unidirectional and bidirectional versions are available, identified by a “C” or “CA” suffix.
The devices deliver a peak pulse power of 500 W, a maximum forward surge current of 40 A, and feature low inductive parasitics for fast response times. They are supplied in tape‑and‑reel form and meet UL94V‑0 flame‑retardant standards.
