Tổng quan
Description
- Meaning: 5.0 ≈ 5 kW peak pulse power (8/20 µs); SMDJ = surface-mount TVS; 12 = nominal stand‑off voltage ~12 V; A usually denotes unidirectional version.
- Function: clamps overvoltage to a safe level, protecting power rails and sensitive electronics.
- Connection: placed across the line and ground (for unidirectional devices, cathode to the positive rail, anode to ground).
- Key specs to check: Vrwm (standoff), Vbr (breakdown), Vclamp (clamping), IPP/peak pulse current, package (DO-214AB), temp range.
- Typical use cases: automotive 12 V systems, telecom power lines, USB/12 V DC rails, consumer electronics.
- Note: exact voltages and currents vary by manufacturer and lot; consult the specific datasheet for precise values and tolerances.
Features
- Unidirectional TVS for clamping positive surges on 12V rails
- Peak pulse power up to about 1500W (8/20 µs)
- Stand-off (working) voltage ~12V; low leakage at rated voltage
- Breakdown voltage typically around 13–15V; clamping voltage ~20–22V (8/20 µs)
- Fast response time (sub-nanosecond to nanosecond range)
- Package: surface-mount DO-214AB (SMDJ) for easy reflow soldering
- Wide operating temperature: -55°C to +150°C
- RoHS compliant; suitable for automotive/industrial environments
- Reputable surge protection device with good reliability and ruggedness
Note: exact voltage ranges may vary by lot; consult the manufacturer datasheet for precise VBR, VCL, and leakage specs.
Pinout
- Function: Transient Voltage Suppressor (TVS) diode in an SMDJ package, used for surge/ESD protection to clamp overvoltage on 12V power rails (unidirectional variant).
Manufacturer
- What kind of company: A global manufacturer of circuit protection and power control components, including fuses and TVS diodes; headquartered in Chicago, USA, with operations worldwide (publicly traded on NASDAQ as LFS).
Application
- Automotive 12 V systems (load-dump and harness surges)
- 12 V DC rails in consumer electronics, industrial controls, telecom equipment
- DC-DC converters, power supplies, inverters, battery management, solar charge controllers
- Surge protection on 12 V input/power lines and battery connections
- ESD/surge protection for 12 V signal lines in infotainment and telematics systems
