Semiconductors & discrete components

Diodes, transistors and thyristors for rectification, switching, protection and power stages in electronic assemblies.

Discrete semiconductors handle rectification, switching, regulation and protection in power supplies, motor drives, chargers and control boards. Enquiries cover diodes, bridge rectifiers, bipolar transistors, MOSFETs, IGBTs and thyristors.

The full manufacturer part number is the most reliable starting point. Marking codes on small SMD packages are short and can be shared by unrelated parts, so a code read from a board may need further checks before a part can be identified.

What to include in an enquiry

The more of these details an enquiry has, the quicker a requirement can be reviewed. A full manufacturer part number or a BOM line covers most of them.

Voltage rating
Current rating
Polarity or channel type
Package

Device type: Diode (rectifier, fast-recovery, Schottky, Zener or TVS), bridge rectifier, BJT, MOSFET, IGBT, or thyristor/SCR.
Voltage rating: Reverse voltage for diodes, drain–source voltage for MOSFETs, collector–emitter voltage for BJTs and IGBTs. For Zener diodes, the Zener voltage and power rating.
Current rating: Average forward current for diodes; continuous drain or collector current for transistors.
Polarity or channel: NPN or PNP for bipolar transistors; N-channel or P-channel for MOSFETs.
Package: For example DO-41, SOD-123, SMA/SMB, SOT-23, TO-92, TO-220 or TO-247 — with the pin-out if it is not the usual one.
Switching characteristics: Where they matter: recovery time for fast-recovery diodes, forward voltage for Schottky diodes, on-resistance and gate threshold for MOSFETs.
