In the vast ecosystem of electronic components, certain part numbers become benchmarks. For many designers working on power supplies, consumer electronics, and industrial controls, the code "SH1 94V0" frequently appears on BOMs (Bill of Materials) and schematic diagrams.
But here is the first hurdle every engineer faces: You cannot simply download a single datasheet for "SH1 94V0." Why? Because this string combines two distinct pieces of information—a specific component series (SH1) and a safety standard (94V-0) . To successfully find a free, accurate datasheet, you need to understand what you are actually looking at.
This article serves as your complete technical resource. We will dissect the SH1 component family, explain the critical UL 94V-0 flammability rating, and—most importantly—provide you with a roadmap to locate and download free PDF datasheets for every variant of the SH1 series. sh1 94v0 datasheet free
The marking SH1 is ambiguous and could mean:
| Possibility | Explanation | |-------------|-------------| | Molded case mark on a component (e.g., transistor, diode, IC) | SH1 might be a date/lot code or a manufacturer’s internal marking. The actual part number is often different (e.g., S1H = diode). | | PCB material designation | Some Chinese PCB suppliers use SH1 as a batch code for FR-4 with 94V-0 rating. | | SH1 series connector or switch | Some manufacturers label a product series as SH1 (e.g., JST SH series connectors – but those are rated 94V-0). | In the vast ecosystem of electronic components, certain
Why is this specific combination (SH1 + 94V-0) so popular? Because it is the workhorse of low-voltage AC to DC conversion.
Once you have identified the likely component type using the guide above, here is how to locate the document: and industrial controls
If the component is a tiny, 5-pin surface mount device (SOT-25 or SC-74 package), it is likely a Toshiba Logic IC.
