Vue d'ensemble

Description

MMBT3904 is the surface-mount version of the classic 2N3904—an NPN small‑signal transistor used for general amplification and switching in SOT‑23 packages. The “215” suffix is not a standard electrical parameter; it’s usually a date/lot/batch code from some manufacturers and does not change performance.
Key specs (typical):
- Vceo: ~40 V
- Ic: up to ~200 mA
- hFE: ~100–300 (depends on Ic and temperature)
- fT: several hundred MHz (small-signal device)
Pinout (SOT‑23, view flat face): Pin 1 Emitter, Pin 2 Base, Pin 3 Collector (verify with the specific datasheet).
Common uses: general-purpose switching, small-signal amplification, sensor interfacing. It’s a drop-in-style replacement for 2N3904 in many designs, with the same biasing and circuit considerations.
Tips: use a base resistor to limit base current; ensure Vce and Ic are within ratings; consider temperature derating for reliability.

Features

Concise features of MMBT3904 (NPN, SMD):
- NPN general-purpose bipolar transistor in a SOT-23 (MMBT) package
- Vceo: 40 V; Ic: 200 mA
- Ptot: ≈ 300 mW (package dependent)
- DC current gain hFE: ~100–300 (typical ~200 at Ic = 10 mA)
- Vce(sat): ≈ 0.25–0.4 V at Ic = 10 mA, Ib ≈ 1 mA
- Transition frequency ft: ~300 MHz (high-speed switching/amplifier use)
- Temperature range: typically -55 to +150 °C
- Features: Pb-free, RoHS-compliant; suitable for general switching and small-signal amplification
- Complementary to MMBT3906 (PNP)
Note: exact limits vary by manufacturer; always check the specific datasheet for the “215” lot/package variant.

Package

SOT-23 3-pin surface-mount package (MMBT3904; 215 is likely a date/lot code).

Pinout

- Pin count: 3 pins (SOT-23 package)
- Function: NPN general-purpose bipolar junction transistor (MMBT3904) used for switching and amplification in low-power circuits
- Pinout (top view, flat side toward you): Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector

Manufacturer

The MMBT3904 (the “,215” is typically a distributor/packaging or ordering suffix) is made by multiple manufacturers; a common maker is ON Semiconductor (onsemi). ON Semiconductor is a global semiconductor company that designs and manufactures discrete semiconductors, analog and power-management ICs, and other integrated solutions for automotive, industrial, communications and consumer markets.

Application

MMBT3904 is a general‑purpose NPN transistor in SOT‑23. Used for low‑power switching and small‑signal amplification. Applications: driving small relays, LEDs, optocouplers; level shifting and buffering between microcontrollers and higher‑voltage circuits; small‑signal amplification in audio/communications; logic inverters/drivers; sensor interfacing and general prototyping (ratings up to ~40 V, ~200 mA).

Equivalent

MMBT3904 (SOT‑23) is the SMD equivalent of the 2N3904 small‑signal NPN transistor. Direct equivalents: 2N3904 (TO‑92), PMBT3904, SMBT3904 and other manufacturers' MMBT3904 variants (ON Semiconductor, Diodes Inc., Rohm, Nexperia). Any small‑signal NPN with similar specs (Vceo ≈40 V, Ic ≤200 mA, similar hFE) can substitute.
