Description
The 1N38A is a germanium general-purpose diode listed in the Agenda radioelectronistului (2nd edition, 1989) among the diodes of IPRS Băneasa, which made it only at the customer’s request; it has a peak reverse voltage VRM of 120 V and comes in a DO-7 (F-2) glass package with 1…3 coloured rings [1]. The package drawing is in the Gallery.
The code is printed „1N 38A”. The table gives a peak reverse voltage VRM of 120 V, a reverse voltage VR of 100 V, a forward current IF of 50 mA, a surge forward current IFSM of 500 mA, a maximum forward voltage VFM of 1 V at IF = 3 mA and a maximum reverse current IRM of 5 µA at VR = 3 V [1].
A note to the table says that these diodes are not made routinely at IPRS-Băneasa, only at the customer’s request („nu se fabrică în mod curent la IPRS-Băneasa, ci doar la cererea beneficiarului”) [1].
