概述

Description

SMAJ130A is a high‑power transient-voltage-suppressor (TVS) diode in an SMA (surface‑mount) package. It protects electronic circuits from voltage transients on roughly 130 V lines.
- Variant: unidirectional version (suffix A).
- Key idea: clamps surges to prevent damage on power rails and high‑voltage lines.
- Typical ratings (datasheet values): VRWM around 130 V (standoff); VBR typically 140–160 V; clamp voltage rises with current.
- Surge capability: very high peak pulse current for short durations (typical for SMAJ family; exact Ipp depends on the waveform and temperature).
- Package/use: compact DO-214AA SMA package; suitable for automotive, telecom, industrial power-supply, and ESD/surge protection.
- Important: exact values (VRWM, Vclamp, Ipp) vary by manufacturer and part revision; consult the specific datasheet for precise numbers and derating.
If you need exact electrical specs and a schematic selection guide, I can pull the latest datasheet notes.

Features

SMAJ130A Features (concise)
- Unidirectional TVS diode in SMA (DO-214AC) package (A variant).
- VRWM (stand-off voltage): 130 V.
- Peak pulse power: 1500 W (10/1000 μs waveform).
- Very fast response time: typically < 1 ns.
- Low leakage at rated voltage; clamps surge energy to protect circuitry.
- Operating junction temperature: -55°C to +125°C.
- Pb-free, RoHS compliant; 100% production-tested.
- Suitable for protecting power rails, data/signal lines, and I/O circuits in telecom, industrial, and automotive environments.

Package

SMAJ130A comes in an SMA package (DO-214AA surface-mount package).

Pinout

- Pin count: 2 pins (DO-214AC SMA package).
- Function: Unidirectional transient-voltage-suppressor (TVS) diode for surge/overvoltage protection. It clamps transients to protect the circuit. Pin 1 = anode, Pin 2 = cathode (cathode side is the band-marked).

Manufacturer

Manufacturer: Vishay Intertechnology, Inc.
What kind of company: Vishay is a global electronics company that designs and manufactures semiconductors and passive electronic components (discretes, resistors, capacitors, diodes, etc.).

Application

- Protection of mains inputs (120/230 VAC) and DC bus rails in power supplies
- DC link protection in SMPS, motor drives, and inverters
- Protection for telecom/network and industrial control equipment
- Protection in solar/energy-storage systems and high-voltage data/power lines against surge and ESD

Equivalent

Equivalent parts are 130 V standoff, unidirectional TVS diodes in SMA package from other vendors. Common cross-references include:
- Vishay SMAJ130A (original)
- Littelfuse SMAJ130A
- ON Semiconductor SMAJ130A / SMBJ130A variants
Note: exact package (SMA vs SMB) and current rating may vary; always verify VRWM, VBR, and package compatibility in the datasheets.
