Description
JAN2N2945A is the JAN designation for the classic 2N2945A NPN silicon transistor. It belongs to the 2N29xx family and is used for general-purpose switching and small‑to‑medium‑signal amplification in older electronics. It’s a Bipolar Junction Transistor with NPN polarity. Depending on lot or vendor, typical ratings are around 60 V collector‑emitter voltage (Vce) and up to about 1 A continuous collector current (Ic), with gain (hFE) that varies with temperature. It was available in metal-can and early plastic packages. The JAN prefix is a cataloging/manufacturer code used by some distributors. For exact electrical specs and packaging, consult the specific datasheet for the device you have.
Features
JAN2N2945A is the military (JAN) version of the 2N2945A NPN silicon transistor. Core features:
- NPN silicon transistor for general-purpose switching/driver roles
- Vceo: around 60 V
- Ic: about 0.5 A (continuous)
- hFE: wide range (approx. 40–160, temperature dependent)
- Low leakage and high reliability (mil-spec screening)
- Temperature range: roughly -65°C to +150°C
- Packaging: military-grade metal can or molded packages (eg, TO-18/TO-39 variants) depending on lot
Note: exact specs can vary by lot and specific JAN grade (JANTX/JAN).
