概述
Description
BAS16LT3G is a RoHS-compliant, surface-mount fast-switching diode in the BAS16 family. It’s intended for fast signal switching and low‑current rectification in small-signal circuits.
Key points:
- Reverse voltage: up to about 75 V; average forward current up to ~200 mA.
- Forward voltage: typically around 1.0 V at low to moderate forward currents.
- Switching performance: fast recovery, suitable for high-speed switching; recovery times on the order of a few nanoseconds.
- Junction capacitance: low to moderate (helps with high-speed performance).
- Package: small SMD package with the LT3G suffix indicating lead-free/RoHS-compliant packaging (tape & reel in many cases). Exact package type varies by manufacturer.
Typical applications:
- Fast switching and signal rectification in low-power circuits
- Level shifting, protection/clamping, and switching regulators
Note: Always verify the exact datasheet for your supplier’s package, ratings, and package marking, since variations exist across manufacturers.

Pinout
Pin count: 3 (SOT‑23 small outline package).
Function: single small‑signal / high‑speed switching diode (two electrical terminals: anode and cathode). The SOT‑23 footprint provides a third pin that is either a no‑connect or tied to one diode terminal (commonly the cathode) for improved thermal/current handling — check the manufacturer datasheet for the exact pin‑mapping for your supplier.
