Übersicht
Description
Typical use cases include protecting USB/power inputs, data lines, and other 5‑V logic rails in consumer electronics.
For precise electrical specifications (standoff voltage, breakdown and clamping voltages, peak pulse power, leakage, temperature range) and exact packaging details, consult the official datasheet from the manufacturer or trusted distributors (Digi‑Key, Mouser, etc.).
Features
- Type: Transient Voltage Suppressor (TVS) diode
- Package: SMB (DO-214AB/BB footprint)
- Configuration: unidirectional (some variants may be bidirectional)
- Stand-off voltage: approximately in the 15 V range (VWM) for this model
- Peak pulse power: high in SMB package (designed for surge protection)
- Fast response time: nanosecond-scale clamping during transients
- Leakage: low at rated stand-off voltage
- Temperature rating: wide range (often -55°C to +125°C)
- Compliance: RoHS; packaging suitable for surface-mount assembly
- Applications: input protection for power rails, USB/HDMI/communication lines, automotive and industrial electronics
For exact electrical specs (VWM, VBR, VC, IPP, leakage, tolerance) and packaging options, please refer to the official datasheet or provide it.
Pinout
Function: It is a TVS (transient-voltage-suppression) diode used to protect circuits from ESD, lightning and surge transients by clamping excessive voltages to a safe level (installed across power rails or signal lines).
Application
- USB/charging ports and 5 V power-input protection
- Low-voltage signal interfaces (microcontrollers, IC I/O, data lines)
- Consumer electronics (phones, tablets, wearables, cameras)
- Telecom/network interfaces and other 5 V logic circuits
- General protection for 5 V rails in appliances and peripheral devices
