概述

Description

BC816-16HR is a general‑purpose NPN silicon transistor in the BC816 family, intended for low‑to‑medium power switching and amplification. The -16HR suffix denotes a specific gain/variant from some manufacturers; exact packaging and tolerances depend on the supplier (TO‑92 or SMD variants), so always check the datasheet.
Typical (vendor‑dependent) specs you’ll see:
- Vceo about 40 V
- Ic up to ~0.5 A
- hFE (gain) broad, often in the hundreds (roughly 100–600, depending on Ic and lot)
Common uses:
- Small-signal amplification
- Switching loads in microcontroller and sensor circuits
How to use:
- Connect in common-emitter configuration; bias the base with a resistor, emitter to ground, collector to the load
- Ensure base current is limited to protect the device and meet required gain
Comparison:
- Similar to BC817/BC846 family parts; choose based on required Vce, Ic, and hFE for your circuit.
Always refer to the specific manufacturer’s datasheet for exact electrical characteristics and packaging.

Features

BC816-16HR features (concise):
- NPN silicon transistor, general-purpose switching/driver amplifier
- Vceo: 45 V
- Ic max: ~0.5 A
- Ptot: ~0.5 W (TO‑92 package)
- DC gain (hFE): wide range (typical ~160–420, varies with Ic and temperature)
- Package: TO‑92 through-hole; RoHS-compliant High-Reliability (HR)
- Temp range: approx. −55°C to +150°C
- Suitable for: generic amplification and switching in low- to medium-current circuits
Note: exact figures vary by lot; consult the datasheet for your lot.

Package

Package can vary by manufacturer, but BC816-16HR is most commonly supplied in a 3‑pin SOT‑23 surface‑mount package. Always confirm the exact package and footprint in the manufacturer's datasheet.

Pinout

The BC816-16HR is a single PNP bipolar junction transistor with 3 terminals (pins): base (B), collector (C) and emitter (E). Its function is general-purpose low-power switching and signal amplification. Note: exact pin numbering (which physical pad is B/C/E) depends on the package variant (SOT‑23 or TO‑92), so check the manufacturer’s datasheet for the precise pin layout.

Application

BC816-16HR is a high-reliability NPN small-signal transistor. Applications: general-purpose amplification and switching in low/medium level signal circuits; buffer/driver stages; relay and LED drive; input stages of audio, sensor, and instrumentation circuits; level shifting and signal conditioning in telecom and computer peripherals; and automotive/industrial equipment where long-term reliability is required.

Equivalent

I’m not sure which BC816-16HR you mean—there are multiple parts with similar codes. Can you provide the manufacturer or a link/datasheet (or tell me if it’s a transistor, regulator, diode, sensor, etc.)? With that I can list accurate direct equivalents.
