Micro-LID Transistors
LDT3251A and LDT3251AT
Description:
The LDT3251A (untinned) and LDT3251AT (tinned) are PNP silicon transistors in
very small, rugged, surface mount, 4-post ceramic packages (Micro International
manufactured package p/n 4-075-1). The LDT3251A and LDT3251AT meet the
general specifications of the 2N3251A transistor. The 4-075-1 Micro-LID package
is a 4-post, leadless ceramic carrier which can be provided with gold metallized
or pre-tinned lands, and is approved for military, medical implant, sensor, and
high reliability applications. The LDT3251A and LDT3251AT can be provided
with special feature options such as additional temperature cycling and
screening.
