概述

Description

BSS138BK,215 is a small-signal N-channel MOSFET in a SOT-23 package. Typical features: VDS about 50V, ID around 180 mA, RDS(on) roughly 3–4 Ω at VGS = 4.5V, and a gate threshold of ~0.6–1.5V, i.e., logic-level operation. It’s commonly used for low-side switching and as a bidirectional level shifter in small I/O and I2C-type circuits. The “BK, 215” part/lot codes usually indicate a specific manufacturer variant and date code; for exact electrical specs, pinout, and package details, consult the manufacturer’s datasheet for the BSS138BK variant.

Features

Here are the typical features of the BSS138BK-215 (BSS138 family) MOSFET:
- N-channel enhancement-mode MOSFET
- VDS: 50 V
- RDS(on): ~3 Ω (typ) at VGS = 4.5 V (range ~2–5 Ω depending on lot/manufacturer)
- Gate threshold (VGS(th)): ~0.8–2.0 V (logic-level device)
- ID (continuous drain current): ~180 mA (varies by package/part)
- Package: SOT-23 (small‑signal, surface-mount)
- Fast switching with low input capacitance
- RoHS compliant / Pb-free
- Temp range: typical -55°C to +125°C (variant dependent)
Note: Exact values can vary by manufacturer and specific BK-215 variant. Consult the manufacturer’s datasheet for precise numbers.

Package

The BSS138BK,215 is supplied in a 3-pin SOT-23 (TO-236AB) surface-mount package; the “,215” suffix denotes tape-and-reel packaging.

Pinout

BSS138BK,215 is a 3‑pin N‑channel enhancement MOSFET (SOT‑23). Pin functions (typical SOT‑23 assignment):
- Pin 1: Gate — control terminal (voltage input)
- Pin 2: Drain — current input / connected to package tab
- Pin 3: Source — current output / reference (return)
In short: 3 pins — Gate, Drain, Source.

Manufacturer

Manufacturer: Diodes Incorporated.
What kind of company: Diodes Inc. is a global semiconductor company that designs, manufactures and supplies discrete semiconductors, logic and analog ICs (including MOSFETs, diodes, rectifiers and switching ICs) for consumer, computing, industrial and automotive markets; it is a publicly traded company (NASDAQ: DIOD).

Application

Applications of BSS138BK (215 variant) include:
- Bidirectional level shifters for I2C/open-drain buses between voltage domains (e.g., 1.8 V to 3.3/5 V)
- Small-signal N-channel MOSFET switch in microcontroller circuits (low-side switching, signal routing)
- General-purpose logic-level switch for low-power portable electronics
- Sensor/actuator interfaces and gate-control in embedded systems
