Product details
Overview
SMAJ130A-E3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping fast-rising voltage transients up to 209 V at 1.4 A peak pulse current, with 400 W peak pulse power (10/1000 μs), 130 V stand-off voltage, and 144–159 V breakdown voltage range. It protects MOSFETs, ICs, and sensor signal lines in industrial motor drives and automotive power modules.
For engineers reviewing the SMAJ130A-E3/61 datasheet, SMAJ130A-E3/61 pinout, SMAJ130A-E3/61 application, or SMAJ130A-E3/61 equivalent, key selection criteria include clamping voltage (209 V), standoff voltage (130 V), unidirectional polarity, SMA package thermal resistance (120 °C/W), and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry, triggered when reverse voltage exceeds its 144–159 V breakdown range. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
Rated for 400 W peak pulse power (derated to 300 W above 78 V), it sustains repetitive 10/1000 μs transients at 0.01% duty cycle on 5.0 mm × 5.0 mm copper pads. The unidirectional configuration features cathode band marking and supports forward surge current up to 40 A (8.3 ms half-sine).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA-E3/61 | Bidirectional variant; symmetric clamping in both polarities; same VWM (130 V), VC (209 V), PPPM (400 W) | Required for AC-coupled or floating signal lines where polarity reversal may occur | Select SMAJ130CA-E3/61 only if bidirectional protection is mandated; otherwise SMAJ130A-E3/61 offers lower cost and simpler layout |
| SMBJ130A-E3/52 | Same electrical specs but in larger SMB (DO-214AA) package; higher thermal mass; RθJA = 85 °C/W vs. 120 °C/W | Better suited for high-repetition-rate surges or elevated ambient temperatures (>85 °C) | Choose SMBJ130A-E3/52 when thermal margin is constrained; SMAJ130A-E3/61 preferred for space-constrained designs |
Compared with SMAJ130CA-E3/61 and SMBJ130A-E3/52, the SMAJ130A-E3/61 delivers optimal balance of compact size, standardized unidirectional clamping, and sufficient surge handling for most industrial and automotive signal-line protection tasks.

FAQ
What is the clamping voltage of SMAJ130A-E3/61 under a 10/1000 μs surge?
The SMAJ130A-E3/61 clamps to a maximum of 209 V when subjected to its rated peak pulse current of 1.4 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88390 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is SMAJ130A-E3/61 suitable for automotive applications?
SMAJ130A-E3/61 itself is commercial-grade; however, the identical device architecture is AEC-Q101 qualified in the HE3 suffix variant (e.g., SMAJ130AHE3_A). For automotive use, specify the HE3 version-SMAJ130A-E3/61 meets all electrical and thermal specs but lacks formal automotive qualification documentation.
What does the "-E3/61" suffix indicate in SMAJ130A-E3/61?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/61" specifies packaging in 7-inch plastic tape-and-reel format with 1800 units per reel. This ordering code aligns with Vishay's standard commercial distribution channel and ensures compatibility with pick-and-place equipment.
How does SMAJ130A-E3/61 differ from SMAJ130CA-E3/61?
SMAJ130A-E3/61 is unidirectional with cathode band marking and conducts only in reverse bias; SMAJ130CA-E3/61 is bidirectional, offering symmetrical clamping for AC signals or floating nodes. Both share identical VWM (130 V), VC (209 V), and PPPM (400 W), but differ in polarity behavior and marking.
What is the thermal resistance of SMAJ130A-E3/61, and how does it affect layout?
SMAJ130A-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. To maintain safe junction temperature under repetitive surges, ensure adequate copper area and avoid thermal bottlenecks in PCB routing near the SMAJ130A-E3/61 footprint.
