DESCRIPTIO
ABSOLUTE
The RH1009 is a general purpose 2.5V shunt regulator
diode designed to operate over a wide current range while
maintaining good stability with time and temperature. The
adjust terminal allows either temperature coefficient to be
minimized or the reference voltage to be adjusted without
changing the temperature coefficient. Because it operates
as a shunt regulator it can be used equally well as a positive
or negative reference.
Reverse Breakdown Current ................................ 20mA

Operating Temperature Range ............. – 55°C to 125°C
Storage Temperature Range ................. – 65°C to 150°C
Lead Temperature (Soldering, 10 sec).................. 300°C

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test in accordance with method
5004 of MIL-STD-883 Class B. The verified failures of group A, subgroup
1, after burn-in divided by the total number of devices submitted for burnin in that lot shall be used to determine the percent for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
