BAS16-QR

BAS16-QR is a variant of the BAS16, a small-signal, fast-switching diode used for general purpose signal switching, clamping, and protection in digital and RF circuits. The “-QR” suffix denotes a specific QR-packaged (SMD) version of BAS16 from a given manufacturer (usually RoHS-compliant) and may have slight package/pinout differences.
Key points:
- Function: fast switching/rectification for low-power signals.
- Packaging: QR-packaged SMD variant (check exact dimensions in the datasheet).
- Typical ratings (manufacturer-dependent): reverse voltage from tens to a few hundred volts; forward current in the low hundreds of milliamps; fast switching with nanosecond-scale reverse recovery; forward voltage around 0.7–1.0 V at rated current.
- Applications: logic-level switching, signal routing, protection/clamping, small-signal rectification.
Why check the datasheet: exact VR, IF(AV), IFSM, Ptot, and package dimensions vary by vendor and QR variant. Use the datasheet for the precise electrical and mechanical specs for your BAS16-QR part.

BAS16-QR is a small-signal, fast-switching diode in an SMD package. Key features (typical):
- VRRM: 75 V; IF(AV): 200 mA; IFSM: ~1 A (surge)
- Fast switching: trr and tf in the low-ns range
- Forward voltage: ~0.9–1.0 V at ~10 mA
- Reverse leakage: very low (nA range at room temp)
- Junction capacitance: a few pF
- Package: RoHS-compliant, surface-mount (QR—tape & reel)
- Applications: high-speed switching, clipping/rectification in compact circuits
Note: exact values can vary by lot; refer to the specific BAS16-QR datasheet for precise numbers.

BAS16-QR comes in a small surface-mount package: SOD-123 (two-lead).

- Pin count: 2 terminals (anode and cathode)
- Function: BAS16-QR is a small-signal, high-speed switching diode used for fast switching/rectification in SMT circuits.
