Overview

Description

BAT46 is a small-signal Schottky diode used for high-speed switching with a low forward drop. Key points:
- Characteristics: fast switching, low forward voltage (VF ~0.2–0.3 V at modest current), moderate current rating.
- Ratings (typical): VRRM about 30 V; IF(AV) around 200 mA (varies by vendor).
- Packages: common SMD options (e.g., SOD-123, SOT-23 variants).
- Applications: RF envelope detectors and mixers, fast rectification, clamping/protection, level shifting, where a fast diode with low VF is advantageous.
- Pros/cons: advantages—low voltage drop and speed; drawbacks—limited reverse voltage and higher leakage with temperature.
Use tip: check the exact datasheet for VRRM, IF, and VF for your manufacturer, as values can vary between part families (BAT46 vs BAT46A/B, package, etc.).

Features

BAT46 features (small-signal Schottky diode)
- Very low forward voltage drop (about 0.2–0.3 V at small currents)
- Fast switching with negligible reverse recovery
- Reverse voltage rating typically around 20–30 V
- Forward current rating up to ~200 mA
- Low junction capacitance, suitable for RF/high-speed use
- Reverse leakage increases with temperature (low at room temp)
- Surface-mount package (available in common formats like SOT-23/SOD-123) and wide availability
Useful for high-speed rectification, clamping, envelope detectors, and RF switching.

Package

BAT46 is a small-signal Schottky diode. In SMD form it is commonly offered in SOD-123 (some vendors also offer SOD-323 or SOT-23 variants).

Pinout

BAT46 is a small-signal Schottky diode. It is a 2-pin device (anode and cathode); in some SOT-23 packages the package has 3 pins total, with the third pin typically unused (NC). It offers low forward voltage and fast switching for high-speed rectification, clamping, or protection.

Manufacturer

The BAT46 isn’t made by a single company; it’s a standard Schottky diode produced by many vendors. A common supplier is Vishay Intertechnology. Vishay is a global electronics components company that designs and manufactures semiconductors (diodes, transistors) and passive components (resistors, capacitors).

Application

BAT46 is a small-signal Schottky diode for high-speed RF applications. Common uses include:
- RF/IF switching diodes in receivers and front-ends
- Envelope and peak detectors in AM/FM demodulation
- Mixer diodes for down-conversion
- Limiter, clamp, and protection circuits at RF/logic nodes
- Fast, low-current rectification and sampling in digital/RF circuits

Equivalent

BAT46 is a small-signal Schottky diode (roughly 40–50 V, ~0.15–0.2 A). Direct equivalents are other vendors’ BAT46 parts (BAT46, BAT46A, BAT46C). Common substitutes include the BAS40 family (Schottky, similar rating in SOT-23/SOD-323) and other 40–60 V, ~100–250 mA diodes from various makers. For higher current, SS14 (40 V, 1 A) can substitute in a pinch, but expect different forward drop and packaging.
