NTE5498 & NTE5499
Silicon Controlled Rectifier (SCR)
12 Amp
Description:
The NTE5498 and NTE5499 silicon controlled rectifiers are high performance glass passivated
PNPN devices in a TO220 type package designed for general purpose high current applications
where moderate gate sensitivity is required.
