Part 2: The SH1 Connector Series – Technical Specifications

The JST SH1 series is an industry standard for compact, high-density connections. It is widely used in consumer electronics, medical devices, and portable gadgets due to its small pitch and reliable contact.

Most Common Match: BSS138 (N-Channel MOSFET)

In 9 out of 10 cases, "SH1" on a SOT-23 package refers to the BSS138 from multiple manufacturers (NXP, ON Semi, Fairchild, etc.).

| Parameter | Value | |-----------|-------| | Function | N-Channel Logic Level MOSFET | | Package | SOT-23 | | ( V_DSS ) | 50V | | ( I_D ) | 220mA | | ( R_DS(on) ) | 3.5Ω (max @ 4.5V) | | ( V_GS(th) ) | 0.8V – 1.5V |

Alternative possibilities for "SH1":

• MMBT4401 (NPN transistor) – rare, check pinout.
• 2N7002 variant – very similar to BSS138 but different ( R_DS(on) ).

✅ Action: Always verify with a multimeter or by tracing the circuit. Do not rely solely on the marking.

Overview

• Component Type: The SH1 94V-0 is likely a type of fuse or a protective device used in electronic circuits.
• UL Rating (94V-0): This rating signifies that the material used for the component has achieved a UL 94V-0 classification. The UL 94 standard is used to assess the flammability of materials used in electrical devices. A 94V-0 rating means the material has demonstrated the highest level of flame retardancy; it does not burn for more than 10 seconds after being exposed to a flame, and it does not drip flaming particles.

7. Final Recommendations

1. Never assume – Use a component tester or measure pin-to-pin capacitance to confirm MOSFET vs. transistor.
2. Keep a SMD code book – Print a reference table for common codes (SH1, 1P, 2F, etc.).
3. For new designs – If you need a 94V-0 rated component (e.g., a plastic case or connector), search the manufacturer's site for "UL 94V-0" + part type.

🔍 Pro tip: If you need the actual datasheet for the component marked SH1, search for "BSS138 datasheet" (NXP/ON Semi versions include the marking code SH1 in the "Marking" section of the document).
