ESD diodes, TVS, surge suppressors, common-mode filters, and resettable fuses — keep transients out of your IC pins and your power rails.
ESD Protection Diodes
Tiny diodes that protect your IC pins from human-body static and other transient events.
TVS Diodes (General)
Workhorse transient voltage suppressors for power rails and lower-speed signal lines.
Load Dump TVS (DO-218)
Heavy-duty TVS purpose-built for automotive 12 V / 24 V load-dump surge events.
Short-to-VBUS Protection
Specialised diodes that protect USB Type-C and other connector pins from accidental shorts to power rails.
Common-Mode Filter + ESD (CMF+ESD)
Two-in-one parts: EMI filter for differential pairs plus integrated ESD protection.
TSS (Thyristor Surge Suppressor)
Crowbar-style surge protectors for telecom and high-energy line protection.
ePoly (Polymer PTC Resettable Fuse)
Self-resetting over-current protection using positive-temperature-coefficient polymers.
Chip Fuses
One-shot over-current protection for fault containment.
LDOs, buck and boost converters, bus converters, PMICs, load switches, and voltage references — generate and gate every rail on the board.
LDO (Low-Dropout Linear Regulator)
Quiet, simple, low-noise voltage regulators for clean rails.
Buck Converter (Step-Down DC-DC)
High-efficiency step-down switching converters for the heart of any modern power tree.
Boost Converter (Step-Up DC-DC)
Step-up switching converters when you need more voltage than your input rail provides.
Bus Converter Chip
Fixed-ratio DC-DC for intermediate-bus and POL distribution.
PMIC (Power Management IC)
Multiple rails, sequencing, supervision, and protection in one integrated chip.
Power Switch / Load Switch (PSW)
Integrated MOSFET switches with controlled turn-on, soft-start, and protection.
Voltage Reference
Stable, low-noise voltage source for ADCs, DACs, and precision analog circuits.
MOSFETs, BJTs, Zeners, Schottkys, switching diodes, rectifiers, and bridges — the workhorse silicon behind every analog and power design.
Zener Diodes
Precision voltage references and clamping diodes for regulation and protection.
Switching Diodes
General-purpose fast-recovery signal diodes for steering, clamping, and small-signal rectification.
Schottky Diodes (SKY)
Low-forward-drop, fast diodes for power rectification and low-loss steering.
Fast Recovery Rectifiers
Silicon rectifiers with short reverse-recovery time for high-frequency power converters.
Bridge Rectifiers
Four-diode AC-to-DC conversion in one package.
MOSFETs
The workhorse switch and amplifier of modern electronics.
BJT (Bipolar Junction Transistors)
Classic current-controlled transistors — still the right choice for analog and low-cost switching.
Analog switches, multiplexers, logic gates, comparators, level shifters, HDMI/DisplayPort boosters, Ethernet PHYs, and current sensors — route, condition, and translate signals.
SPDT Analog Switch
Single-pole double-throw analog switching for signal routing.
Multiplexer (MUX)
Many-to-one signal routing for sensor scanning and channel selection.
Logic Gates
Single-gate and small-scale CMOS logic for glue, level shifting, and signal conditioning.
Voltage Comparator
Convert analog voltage to digital logic level.
Level Shifter
Bidirectional voltage-domain translation for mixed-voltage systems.
HDMI / DisplayPort Signal Booster
Re-driver / re-timer ICs that restore signal quality on long display cables.
HDMI to VGA Converter
Digital-to-analog video converter for legacy VGA monitors and projectors.
Ethernet Controller (PHY / MAC)
Network interface ICs bridging digital data to twisted-pair copper.
Current Sensor
Measure DC or AC current without breaking the wire — Hall-effect and shunt-based options.
