Overview
Description
BAT46W is a small‑signal Schottky diode in the BAT46 family, with the “W” suffix indicating a specific SMD package variant. It’s chosen for high-speed switching and very low forward voltage drop, making it useful in detectors, demodulators, clamp/clip circuits, and fast rectifiers in compact electronics. Typical advantages include Vf≈0.2–0.4 V at modest current and very fast switching (negligible reverse recovery). Typical ratings (which vary by manufacturer) are on the order of tens of volts reverse voltage (VRRM ≈ 20–30 V) and a forward current in the low hundreds of milliamps range. The diode is polarity sensitive (cathode marked on the package). For exact electrical limits, package type, and operating temperature range, consult the specific BAT46W datasheet from the manufacturer you’re using.
Equivalent
BAT46W is a dual Schottky diode (SOT‑23). Direct equivalents are the same BAT46W offered by other manufacturers (Vishay, Diodes Inc., Nexperia, ROHM). Close substitutes include BAT46 (other SMD variants) and BAT54W / BAT54S (dual Schottky in SOT‑23). Always compare Vf, IR and VR ratings and package pinout in datasheets before substituting.
Features
BAT46W is a small-signal Schottky barrier diode in an SMD package (W variant). Key features:
- Very low forward voltage drop (low VF)
- Ultra-fast switching with negligible reverse-recovery time
- Suitable for high-speed rectification, clamping, demodulation, and protection
- Low leakage at room temperature (increases with temperature)
- Reverse-voltage rating in the tens-of-volts range; forward current in the few hundred mA range (per exact part)
- RoHS compliant, Pb-free; available in compact W-package for surface-mount assembly
Note: Check the specific datasheet for exact VR, IF, and package details for a given manufacturer.

Pinout
BAT46W is a small‑signal Schottky diode with 2 pins: anode and cathode. Its function is low‑forward‑voltage, fast switching rectification (signal detection, clamp, polarity protection and high‑speed switching). Typical use: small‑signal/low‑voltage rectification and protection in RF and digital circuits.
Manufacturer
The BAT46W is a small-signal Schottky diode produced by multiple semiconductor component manufacturers (examples: Vishay Intertechnology, Diodes Incorporated, Nexperia, Micro Commercial Components, ON Semiconductor). These manufacturers are electronic semiconductor companies—designers and producers of discrete semiconductor devices and components (diodes, transistors, ICs and related parts) that supply parts for consumer, industrial, and communications electronics.
Application
BAT46W is a fast, low-forward-voltage small-signal Schottky diode. Common applications include:
- RF front‑end blocks (envelope detectors, demodulators, mixers)
- high‑speed switching and sampling circuits
- clamping/protection for IC inputs and logic lines
- peak-detector and rectifier circuits in low‑voltage supplies
- general detector/clipper circuits in compact analog/digital designs
Widely used for fast switching with low distortion and minimal forward drop in signal-processing stages.
