概述

Description

BAT46W is a small-signal Schottky diode in the BAT46 family, optimized for fast switching and a very low forward voltage drop. The “W” suffix identifies a specific SMD package variant; exact package and ratings vary by supplier, so check the datasheet.
Key points:
- Type: Schottky diode (low Vf, fast recovery) used in RF/detector, clipping, protection, and logic circuits.
- Packaging: a vendor-specific SMD variant (W). Verify with the supplier.
- Electricals (typical, vendor dependent): Vr commonly tens of volts (often ~20–60 V); If(max) in the few hundred mA range; Vf(on) about 0.2–0.3 V at modest current; very fast switching and low junction capacitance.
- Pros/cons: advantages—low forward drop, high-speed; disadvantages—leakage increases with temperature.
- Use tips: observe cathode marking for orientation; consider leakage and temperature effects for accuracy.
For precise values, consult the specific BAT46W datasheet from your chosen manufacturer.

Features

BAT46W is a small-signal Schottky barrier diode. Key features:
- Very fast switching with negligible reverse recovery
- Low forward voltage drop (VF ≈ 0.25–0.40 V at typical operating currents)
- Reverse voltage rating around 30 V (VRRM)
- Continuous forward current about 200 mA
- Low junction capacitance suitable for RF/high-frequency use
- Low reverse leakage
- Surface-mount (W‑series) package for compact designs
Ideal for high-speed, low-voltage rectification, clamping, detector, and demodulation applications.

Package

BAT46W is a small-signal switching diode in an SMD SOD-323W package.

Pinout

- Pin count: 3 pins (SOT-23 package)
- Function: Dual Schottky barrier diode with a common cathode (two diodes share the cathode; anodes on the other two pins). Used for high-speed switching, rectification, signal OR-ing, and clamping.

Manufacturer

Common manufacturer: Vishay Intertechnology (one of several vendors that produce BAT46W). Vishay is a global semiconductor company that designs and manufactures discrete semiconductors and passive electronic components (diodes, transistors, resistors, capacitors, etc.).

Equivalent

BAT46W is a dual Schottky diode in one SOT-23 package (two diodes). Equivalents depend on topology and packaging:
- Dual in SOT-23: BAT54S (common-cathode).
- Single-diode substitutes (same family): BAT46.
- Other Schottky cross-refs: 1N5817/1N5819 (through-hole), SS14 (SMD).
Note: check ratings (about 30V, ~200 mA) in the datasheets and ensure package/wiring matches your design.
