概述

Description

BAT46WJ-QX is a variant of the BAT46 family of small-signal Schottky barrier diodes. It provides fast switching and a low forward voltage drop, suitable for high-speed rectification, clamping, and detector circuits in compact surface-mount designs.
Key points:
- Type: Schottky diode (low VF, fast switching)
- Typical family ratings: VR around 30 V; IF around 200 mA (check exact part)
- Forward voltage: typically ~0.2–0.3 V at modest currents
- Package/variant: WJ indicates a specific SMD package; QX is a lot/date code
- Applications: DC-DC converters, input/output clamping, demodulation, protection, high-speed switching
Note: Exact electrical ratings and footprint depend on the manufacturer and the WJ variant. For precise values (VR, IF(AV), VF, IFSM, and package details), consult the specific datasheet from the supplier.

Features

Here are concise features for BAT46WJ-QX (small-signal Schottky diode):
- Type: Schottky barrier diode, fast switching (no minority-carrier storage)
- VRRM (reverse voltage): 40 V
- IF(AV) (continuous forward current): about 150 mA
- IFRM/IFSM (pulsed forward current): typically several hundred mA
- Forward voltage (VF): ~0.25–0.35 V at low current; up to ~0.4–0.5 V at higher currents
- Leakage current (IR): very low at room temp; increases with temperature
- Switching speed: very fast due to Schottky construction
- Junction temp range: typically −55 to +125°C (check datasheet for exact range)
- Packaging: standard SMD, RoHS-compliant/lead-free (variant-dependent)
- Applications: high-speed rectification, clamping, protection, logic-level shifting, demodulation
Note: exact values depend on the specific BAT46WJ-QX package/version. Refer to the official datasheet for precise ratings and tolerances.
