1SS351-TB-E

I’m not sure which device uses the part number 1SS351-TB-E—could you share the manufacturer or field (e.g., automation, sensors, power electronics) or a link? With that, I can give a precise intro. If you want a quick generic idea, here’s what such a code usually implies:
- Type/Family: A specific product line and variant (the “1SS351” part) plus option codes (like “TB-E” for connectors or enclosure type).
- Function: What the item does (sensor, relay, terminal block, interface module, etc.).
- Key specs: Typical voltage/current ranges, operating/ambient temperature, communication or mounting features.
- Applications: Common use in automation, control panels, or equipment interconnects.
- How to find more: Check the official datasheet or product page; compare with cross-reference guides; note any regional part differences.
Share the manufacturer or a link, and I’ll give a concise, accurate intro tailored to that exact part.

Here are typical features of the 1SS351-TB-E (small-signal transistor, TB-E packaging):
- Type: Single silicon small-signal transistor (1S family)
- Package: Tape & Reel (TB-E) for automated assembly
- RoHS compliant / Pb-free
- Applications: general-purpose amplification and switching in low-power circuits
- Electrical characteristics (depends on vendor): high current gain (hFE), low leakage, and fast switching; exact Vceo, Ic, and hFE vary by lot—check the specific datasheet
- Temperature range: suitable for broad operating temperatures (industrial/consumer ranges)
- Packaging suitability: compatible with standard surface-mmount processes
Note: exact electrical ratings (Vceo, Ic, hFE, etc.) vary by manufacturer and lot. Please refer to the specific vendor’s datasheet for precise parameters.

1SS351‑TB‑E is a two‑pin device (anode and cathode). Its function is a small‑signal / high‑speed switching diode (surface‑mount). The “‑TB‑E” suffix typically denotes tape‑and‑reel packaging and lead‑free/halogen‑free finish. Check the manufacturer's datasheet for exact package (SOD‑523/SOD‑323 variations) and electrical specifications.

Manufacturer: Toshiba Electronic Devices & Storage Corporation (Toshiba).
What kind of company: Toshiba is a Japanese multinational electronics and semiconductor manufacturer that designs and produces discrete semiconductors (diodes, transistors), integrated circuits, power devices, sensors and other electronic components for consumer, industrial and automotive markets.

I can’t identify 1SS351-TB-E without the manufacturer or product type. Please share the category (sensor, switch, relay, valve, etc.).
If it’s a sensor/switch, typical applications:
- Machine automation, conveyors, robotics
- Packaging lines, process monitoring
- Safety interlocks and area sensing
If it’s a relay/solenoid:
- Motor, pump, valve control
- Automation panels and power switching
Provide the exact product type for precise, concise application areas.

The 1SS351-TB-E is in a SOD‑523 (chip diode) package; the “-TB-E” suffix denotes tape-and-reel packaging for pick-and-place assembly.
