I am trying to locate an NPN transistor #2SD1835. I did an NTE cross
reference and no luck. I have other components I need to order and am
trying to keep from ordering from more than one supplier to avoid
additional shipping charges. I usually order from Mouser who always
has the NTE part. I tried searching Mouser using the transistor data I
have but got no results. Is this an oddball transistor, or is it a
familiar with a different component number? Thankyou for any help.

If you find the data for the 2SD1835 I'm sure you could find a suitable
replacement. Just because it doesn't appear in a cross-reference book doesn't
make it an oddball.

According to the data sheet, it's only a little TO92 transistor, allbeit
specced as a 'high current switching' transistor. It appears to be nothing
special, with just general purpose applications stated for it. When I come
across one of these little TO92's that has failed in a 'high current'
application like in part of a power supply regulator or switching the supply
to hifi's CD section or whatever, I just fit whatever comes to hand with a
TO126 (small flatpak) outline. A BD131 is usually good for the job, although
there are plenty of similar 2S series Jap transistors as well. It has the
same E-C-B pinning (with the metal pad away from you, as the TO92 (flat
towards you), and the same pin pitch, so can just drop in the original
holes.

You can always sleeve one lead and cross it over , in combination perhaps
with rotating 180 degrees if current, gain , voltage, and frequency
otherwise match or excede but the pinning is wrong for direct pin for pin
replacement.

Thanks for the reply. Sounds like this is pretty straight forward
since I have a Mouser catalog. Thanks.

Thanks for relpying. I will try this as a sub. Looks like it is more
than capable.

Hello,

According to the Japanese spec book I've got:

2SD1835 - (NPN)
60V(CBO)
50V(CEO)
2A
750mW
200h(FE)
150MHz(f(T))
compliment to a 2SB1229


I THINK (but am not positive) that the pinout, with the flat side facing
you is:

Emitter - Collector - Base

There is nothing really special about this transistor except it is
rated for rather high current for a tall TO-92 case. On the other hand,
you might be able to use a TO-126 or TO-220 case device if there is room
for one. I think a ZTX-653 would do the job too.

My vrt databook says ...

Si-N , S, lo-sat, 60V, 2A, 150MHz, 35/580ns, pinout BCE

So it looks like a switching transistor, with low VCEsat. These are
often used to drive the motors in RC cars.

The databook suggests 2SC3328 as a substitute.
