BCX56-16,115

BCX56‑16 and BCX56‑115 are variants in the BCX56 family of high‑voltage, general‑purpose silicon transistors. They are used for small‑signal amplification and switching in mid‑voltage, low‑to‑medium‑current circuits.
Key points:
- They come in common through‑hole packages (e.g., TO‑92) and are chosen for their gain variety and voltage handling.
- The suffixes -16 and -115 denote different gain (hFE) bands or production variants; exact electrical values differ by version and by supplier.
- Typical applications include audio/preamp stages, drivers, and general switching roles; always verify Vceo, Ic, and hFE in the specific datasheet.
Bottom line: both belong to the same BCX56 family, offering similar packaging and purpose but with different gain/lot characteristics. For precise specs and interchangeability, consult the manufacturer’s datasheet for the exact variant you’re using.

BCX56-16,115 refers to a BCX56 family NPN silicon transistor (general purpose) in a small package.
Key features (typical; exact values depend on manufacturer and lot):
- Type: NPN, silicon, epitaxial planar
- Package: TO-92 (variant may differ by supplier)
- Vceo: ~60 V
- Ic: up to ~0.5 A
- hFE: ~100–600 (depends on Ic and temperature)
- Switching/Amplification: suitable for general switching and small-signal amplification
- Power dissipation: ~0.3–0.5 W (depends on package, mounting)
- Temperature range: roughly −55 °C to +150 °C
- Other: RoHS/compliant variants available
Note: exact electricals for the “16,115” variant can vary by manufacturer—check the specific datasheet for precise numbers.

BCX56 is a 3‑lead bipolar transistor. Its pins are: Base (control), Collector, and Emitter.
Typical TO‑92 pinout (flat face toward you, leads down) is: pin 1 = Collector, pin 2 = Base, pin 3 = Emitter — but package pinouts can vary by maker, so always confirm with the specific datasheet for the “BCX56‑16” / “BCX56‑115” variant.

Manufacturer: NXP Semiconductors (originally Philips Semiconductors). NXP is a Dutch multinational that designs and manufactures semiconductors, including discrete transistors and integrated circuits.
