The **M5R76TLJ-R** is a specific surface-mount electronic component, typically identified as a **Zener Diode** or a **Transient Voltage Suppressor (TVS)**, often manufactured by companies like Rohm Semiconductor or similar specialized discrete component producers. --- ### 1. General Specifications Based on the part numbering convention (commonly found in the M-series of small-signal discretes), here are the typical technical characteristics: | Property | Description | | :--- | :--- | | **Component Type** | Zener Diode / Voltage Regulator | | **Package Type** | SOD-323 or similar (Ultra-compact Surface Mount) | | **Polarity** | Unidirectional (Cathode mark present) | | **Configuration** | Single Diode | | **Mounting Style** | SMD/SMT | ### 2. Key Electronic Functions The M5R76TLJ-R serves three primary roles in an electronic circuit: 1. **Voltage Regulation:** It maintains a fixed output voltage across its terminals despite changes in the input voltage or load current, provided it is operated in the "breakdown" region. 2. **Circuit Protection:** It acts as a clamping device to prevent high-voltage spikes from damaging sensitive downstream components (like microprocessors or sensors). 3. **Reference Voltage:** It can provide a stable reference point for analog-to-digital converters (ADCs) or operational amplifier circuits. --- ### 3. Package and Pinout Data The "TL" in the suffix often refers to the **Tape and Reel** packaging specification used for automated pick-and-place assembly machines. | Pin Number | Name | Function | | :--- | :--- | :--- | | **1** | Cathode | The negative terminal (marked with a band/stripe) | | **2** | Anode | The positive terminal | --- ### 4. Typical Applications * **Mobile Devices:** Used in smartphones and tablets for battery charging protection. * **Power Supplies:** Used in the feedback loop to stabilize DC output. * **Data Lines:** Protecting I/O ports from Electrostatic Discharge (ESD). --- ### 5. Identification Marking Because the component is tiny, the full part number `M5R76TLJ-R` is rarely printed on the body. Instead, it usually carries a **2 or 3-character marking code** (e.g., "M5" or "R7"). Always consult the specific manufacturer's datasheet to cross-reference the marking code with the electrical parameters.
