The SMTD995 (P/N 152-0140-01) is a 10 mA, 8 pF tunnel diode with a maximum capacitance of 8 pF in a DO-17 case.
- Note: There is a 152-0140-00 that is a different diode (1N3848) in a different package, with a higher capacitance.
It is used in the 547 units with serial numbers 11890 and up.
According to Craig Sawyers' Diode Reference, it is used in the RM546, RM547, RM585A, R544, R556, R7912, S-51, S-52, TU-5, 067-0572-00, 067-0572-01, 067-0681-00, 1S1, 1S2, 1502, 21A, 22A, 3T5, 3T6, 475/R, 475A/R, 475M, 544, 546, 547, 556, 581A, 585A, 7B52, 7B53N, 7B70, 7B71, 7D10, 7D11, 7T11, and 7T11A.
