Visão Geral

Description

BAW56 is a family of small‑signal silicon transistors (NPN) used for general-purpose amplification and switching in vintage and hobby circuits. Variants BAW56, BAW56A, BAW56B mainly differ in their current‑gain (hFE) ranges. The suffix “215” is not a separate electrical spec; it’s typically a lot, date, or packaging code. Because pinouts and exact electrical ranges can vary by vendor and package (TO‑92, SOT‑23, etc.), always consult the specific datasheet for your exact part and package when designing or substituting.

Equivalent

BAW56 is a dual small‑signal fast switching diode. Equivalents (same function and similar ratings) include: Nexperia BAW56A/BAW56; 1N4148DW (SMD dual); MMBD4148 (dual); BAV99 (dual fast diodes). Exact cross depends on package and voltage/current specs. Please share package type (SOT-23, SOD-123, etc.) and VR/IF to get precise cross-references.

Pinout

Pin count: 3 pins.
Function: Dual silicon switching diodes in one package (two diodes sharing a common node; the variant may be common-anode or common-cathode). Used for high-speed switching in signal paths.

Manufacturer

There isn’t a single “manufacturer” for BAW56,215. BAW56 is a generic part number used by multiple vendors, and 215 is likely a date/lot code. To identify the maker you’d need the package logo or the manufacturer’s marking on the part or its datasheet.
Common manufacturers of BAW56 include:
- Vishay Intertechnology
- Nexperia
- Diodes Incorporated
- ON Semiconductor
What kind of company:
- Vishay Intertechnology: a global leader in discrete semiconductors and passive components (resistors, capacitors, inductors) with manufacturing, testing, and distribution worldwide.

Application

BAW56 (NPN) and BAW215 (PNP) are small-signal, high-frequency transistors. Applications: general‑purpose amplification and switching in RF/IF front‑ends, audio preamps, detectors and mixers, oscillators, and bias networks; often used as complementary pairs in push‑pull stages or as signal switches in compact circuits.

Package

SOT-23, 3-pin surface-mount package (dual diode in one package).
