The **IMZ2AL-AL6-R** is a specific surface-mount electronic component, typically identified as a **General Purpose Dual Transistor** (specifically a dual PNP/NPN or similar complex transistor array) manufactured by **Rohm Semiconductor**. --- ## 1. Component Overview The IMZ2 series is designed to save board space by integrating two independent transistors into a single small-outline package. The "AL6-R" suffix typically refers to the specific taping, reel size, and lead-free compliance. ### Technical Specifications | Parameter | Description | | :--- | :--- | | **Component Type** | Complex Transistor (Dual) | | **Configuration** | Two independent transistors in one package | | **Package Style** | SMT (Surface Mount) / SC-74 (also known as SMT6) | | **Polarity** | Often NPN + PNP (depending on specific sub-series) | | **Mounting Type** | Surface Mount | | **Operating Temperature** | -55°C to +150°C | --- ## 2. Key Internal Features The IMZ2AL functions as a space-saving solution for switching and amplification. * **Integrated Design:** It contains two discrete chips inside one mold. * **High Reliability:** Manufactured using epitaxial silicon technology. * **Low VCE(sat):** Low collector-emitter saturation voltage allows for efficient switching with minimal heat dissipation. * **Complementary Pair:** Usually used in push-pull circuits or as dual-channel signal switches. --- ## 3. Package and Pinout (SC-74 / SMT6) The device uses a 6-pin SMT package. While internal configurations can vary, a typical dual-transistor pinout for this series is as follows: | Pin Number | Function (Typical) | | :--- | :--- | | **1** | Emitter 1 | | **2** | Base 1 | | **3** | Collector 2 | | **4** | Emitter 2 | | **5** | Base 2 | | **6** | Collector 1 | --- ## 4. Typical Applications Because of its small footprint and dual-channel capability, the IMZ2AL is found in: 1. **Mobile Devices:** Power management and signal logic in smartphones. 2. **Logic Gate Implementation:** Building simple AND/OR logic gates on PCBs. 3. **Driver Circuits:** Driving LEDs or small relays. 4. **Signal Inverters:** Using one transistor as an inverter and the other as a buffer. --- ## 5. Equivalent/Substitution Considerations If you are looking for a replacement, ensure the following parameters match: * **V(BR)CEO:** Collector-Emitter Breakdown Voltage. * **IC:** Maximum Collector Current. * **hFE:** DC Current Gain. * **Package Dimensions:** Must be SC-74 (SMT6) to fit the existing footprint.
