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?
An SOD-523 ESD protection diode is a transient voltage suppressor in the JEDEC SOD-523 (SC-79) surface-mount package, roughly 1.6 × 0.8 × 0.6 mm, that clamps electrostatic discharge and short spikes before they reach an IC. It protects because it switches from high impedance to a low-impedance avalanche path in under a nanosecond, shunting ESD … Read more
What Is a Voltage Regulator Zener Diode?
A Zener regulator is sized by its worst case, not its typical load. What a real low-power Zener specifies, and how the series resistor is chosen from those numbers.
600 W TVS Ratings: Pulse Waveform, Temperature and Derating
A 600 W TVS diode is rated on a 10/1000 us pulse and only 350 W at 150 C junction. What the class covers, and the three rows that cause surprises.
1500 W TVS Ratings: Pulse Energy and Protection Coordination
A 1500 W TVS diode is rated in power but chosen in joules: about 1.5 J per pulse, against a load dump worth hundreds. What the class really covers.
Low Capacitance ESD Diode: Protecting High-Speed Signal Integrity in Modern Electronics
A low capacitance ESD diode keeps 3.5 pF off a high-speed line. Why 45 pF parts are wrong there, and how capacitance, clamping and IEC levels decide.
USB ESD Protection Diodes: Selection, Pin Mapping and PCB Layout
A USB ESD protection diode diverts a short electrostatic-discharge transient away from vulnerable circuitry while adding as little loading as practical to the normal signal. Selection depends on the protected pin: high-speed data, configuration, sideband and power pins have different voltage and signal-integrity requirements. A diode rating alone does not prove that the finished port … Read more
