What Is a SOT-23 Bipolar Transistor?
A SOT-23 bipolar transistor fixes footprint, pinout, thermal path and marking. How the outline sets usable current, and when to move to a smaller package.

What Is a General Purpose NPN Transistor?
A general-purpose NPN transistor is a ratings envelope: 40 V, 200 mA, gain 100-300. How to size the base resistor, and when a MOSFET is the better answer.
What Is a Small Signal Schottky Barrier Diode?
A small-signal Schottky diode trades leakage for a 410 mV forward drop. What three real parts specify, and the calculation that decides whether it fits.
What Is a SOT-23 Switching Diode?
SOT-23 is a package, not a specification: the same 100 V, 4 ns switching silicon ships in six outlines. What the outline decides, and what it does not.
SMD Zener Voltage Regulator: Reliable Board-Level Protection And Stabilization
An SMD Zener regulator is rated by its pad: 350 mW standard footprint against 590 mW with 1 cm2 of cathode copper. How the layout sets the budget.
Precision Zener Reference Diode: Stable Voltage In Demanding Power Designs
A precision Zener reference is a tolerance grade: 33 mV at 1 % against 165 mV at 5 % on a 3.3 V rail. What that means for a 12-bit measurement.
High Speed Switching Diode: Optimizing Fast Recovery for Power Electronics and Signal Integrity
A high-speed switching diode is specified by a 4 ns recovery at 10 mA and defined conditions, plus 1.5 pF of capacitance. What the test line decides.
SOD-123 Switching Diode: Fast, Reliable Signal Control for Compact Electronics
A SOD-123 switching diode is a package choice: the same 100 V, 4 ns silicon comes in seven outlines. What the outline changes, and what it does not.
What Is CAN Bus ESD Protection?
CAN bus ESD protection is a capacitance budget first: a two-line part must clamp 30 kV and still add only 25 pF per line. What the numbers decide.
What Is an Automotive ESD Suppressor?
Device ESD immunity is quoted to IEC 61000-4-2, vehicle testing to ISO 10605, and parts to AEC-Q101. What an automotive ESD suppressor must prove.
What Is a Multi Line ESD Protection Array?
A multi-line ESD array is chosen by per-line capacitance and channel count, not by package size. What three real arrays specify, and where each one belongs.
What Is an SOD-523 ESD Protection Diode?
Learn how to select an SOD-523 ESD protection diode with verified package dimensions, TVS polarity, capacitance, voltage ratings and PCB layout checks.
