Descripción general

Description

SMAJ14A is a transient voltage suppressor (TVS) diode in an SMA (DO-214AC) package. It provides surge protection for 12–14 V rail systems with high peak pulse power.
- Type: unidirectional TVS diode
- Package: SMA (DO-214AC)
- Power rating: ~1.5 kW peak pulse power (10/1000 µs)
- Key voltages: VRWM ≈ 14 V; breakdown around 15–18 V; clamping voltage rises with current (typical ~20–25 V at its rated surge)
- How to connect: cathode to the positive rail, anode to ground
- Applications: automotive and industrial DC rails, telecom power inputs, surge/ESD protection
- Notes: exact specs (Vbr, clamping, IPP) vary by manufacturer—check the datasheet for your part.
If you need, I can pull typical specs from a specific manufacturer.

Features

SMAJ14A Features:
- Unidirectional transient voltage suppressor diode (TVS)
- Package: SMA (DO-214AC)
- Stand-off voltage (VR): 14 V
- Peak Pulse Power (PPP): 1.5 kW (8/20 µs)
- Very fast response to transients; clamps surges to protect circuits
- Low leakage in normal operation
- Wide operating temperature: typically from -55°C to +125°C
- RoHS compliant; suitable for surface-mount applications
- Commonly used for 14-V rail protection in automotive/telecom/power circuits

Package

SMAJ14A uses the DO-214AA (SMA) surface-mount package.

Pinout

Two pins. It is a unidirectional transient-voltage-suppressor (TVS) diode in an SMA (DO-214AC) package, used to clamp voltage spikes and protect circuits. It has anode and cathode terminals (cathode usually marked with a band). The “A” suffix denotes unidirectional behavior.

Manufacturer

- Manufacturer: Vishay Intertechnology, Inc. (Vishay)
- What kind of company: A global electronics components company that designs and manufactures semiconductors (including TVS diodes) and passive components (resistors, capacitors, inductors) for automotive, industrial, and consumer markets.

Application

SMAJ14A is a 14 V rated transient-voltage-suppressor diode. Applications include:
- Automotive 12–14 V systems (ECUs, sensors, infotainment)
- DC power-supply and charger input protection
- Battery/charging circuits
- Industrial controls and power-distribution protection
- Telecom/network equipment
- Protection of 12–14 V data/signal interfaces

Equivalent

Equivalents (14V unidirectional TVS diodes):
- SMBJ14A series (DO-214AB): available from major vendors such as ON Semiconductor, Vishay, Littelfuse.
- P6KE14A (DO-204AL): a common 600W alternative if a different package is acceptable.
Note: SMAJ14A is the SMA (DO-214AA) package version; cross-referencing to SMBJ14A or P6KE14A is typically possible depending on footprint/power needs.
