NSVMMUN2235LT1G

NSVMMUN2235LT1G is a part number for a dual digital transistor (MMUN2235) from ON Semiconductor. It integrates two NPN transistors with built-in base resistors in a single package (SOT-23 style, LT1G).
Key points:
- Two NPN transistors with internal base resistors, designed to simplify driving logic loads from microcontrollers.
- Enables direct connection to a MCU pin without external base resistors; typically used for switching LEDs, small relays, or similar loads.
- Commonly used in low-power switching circuits; helps reduce BOM and simplifies design.
- Package: small SMD (often SOT-23) with three pins (two inputs/one common emitter or each transistor’s pins depending on variant).
What to do:
- Look up the datasheet (MMUN2235LT1G) for exact pinout, current/voltage ratings, and whether emitters are common.
- Use as a low-side switch: drive the transistor input from a MCU, connect the load to Vcc and the transistor’s collector to the load.

I don’t have enough confidence identifying NSVMMUN2235LT1G. Please confirm the manufacturer or upload the datasheet (or tell me its function, package, voltage, current and pinout). Once you do, I can quickly list direct equivalents (matching function, pinout and key ratings) and close substitutes from major vendors.
