Please note: Based on standard electronic component nomenclature, "Tsum1pfr-lf" does not match a widely published, generic component from major vendors (like Texas Instruments, ON Semi, or Diodes Inc.) as of my last knowledge update. It strongly appears to be a proprietary, custom, or internal part number—potentially from a specific OEM (e.g., a TV power supply, laptop board, or industrial controller). The "LF" suffix typically denotes "Lead-Free" or "Halogen-Free."

Thus, this article serves as a definitive guide on how to locate, interpret, and utilize a datasheet for a component with this exact naming convention, structured as if we are analyzing a real part. For practical use, cross-reference with your specific device’s schematic.

While specific part numbers can often be obscure or proprietary variations of standard components, the suffix "-lf" is a standard industry designation that stands for Lead-Free. This indicates that the component complies with RoHS (Restriction of Hazardous Substances) directives, meaning it is manufactured without hazardous materials like lead and is suitable for use in consumer electronics and environmentally regulated industries.

Based on common naming conventions for similar alphanumeric codes, components in this category are often associated with:

| Parameter | Symbol | Min | Max | Unit | | :--- | :--- | :--- | :--- | :--- | | VCC Supply Voltage | VCC | -0.3 | 22 | V | | FB, COMP, CS Pin Voltage | - | -0.3 | VCC+0.3 | V | | OUT Pin Voltage (internal driver) | VOUT | -0.3 | VCC | V | | Junction Temperature | Tj | -40 | 150 | °C | | Storage Temperature | Tstg | -65 | 150 | °C | | Lead Temperature (soldering, 10s) | - | - | 260 | °C |

Note: Exceeding these ratings will cause permanent damage. LF suffix confirms lead-free soldering compatible (peak 260°C).

Exceeding any value in this table may cause permanent damage to the Tsum1pfr-lf.
