Product details
Overview
SMCJ130A-E3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 130 V standoff voltage (VWM), 209 V clamping voltage (VC) at 7.2 A peak pulse current, and 1500 W peak pulse power rating for 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive power systems.
For engineers reviewing the SMCJ130A-E3/9AT datasheet, SMCJ130A-E3/9AT pinout, SMCJ130A-E3/9AT application, or SMCJ130A-E3/9AT equivalent, key selection criteria include unidirectional polarity, 1500 W surge capability, 130 V working voltage, RoHS-compliant matte tin plating, and AEC-Q101 qualification eligibility via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its 144–159 V breakdown range (VBR at 1 mA). Its low incremental surge resistance and fast response time enable effective suppression of sub-microsecond transients induced by load dump or relay switching.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power under JEDEC-standard 10/1000 μs waveform while maintaining thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead).
Key Specifications

|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 144 V / 159 V at 1 mA - Confirmed breakdown threshold range for reliable turn-on margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52T | Lower PPPM (600 W), same VWM/VC, SMB (DO-214AA) package | Reduced surge capacity; suitable only for non-automotive, lower-energy transients | Select when board space is constrained and peak surge energy does not exceed 600 W |
| SMCJ130CA-E3/9AT | Bidirectional variant; identical VWM, VBR, VC, and PPPM; no polarity marking | Required for AC-coupled or floating signal lines where voltage polarity reverses | Choose for bidirectional protection needs-no change in layout but removes cathode orientation requirement |
Compared with SMBJ130A-E3/52T, SMCJ130A-E3/9AT provides 2.5× higher surge power handling in the same footprint family; versus SMCJ130CA-E3/9AT, it offers polarity-specific clamping optimized for DC rails with defined ground reference.

FAQ
What is the clamping voltage of SMCJ130A-E3/9AT at its rated peak pulse current?
The SMCJ130A-E3/9AT has a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current (IPPM) of 7.2 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream components connected to the protected line.
Is SMCJ130A-E3/9AT RoHS-compliant and halogen-free?
Yes, SMCJ130A-E3/9AT carries the "E3" suffix, indicating it is RoHS-compliant and manufactured to commercial-grade specifications. It is not halogen-free; for halogen-free compliance, the "M3" suffix variant (e.g., SMCJ130A-M3/9AT) must be selected per Vishay's ordering matrix.
Does SMCJ130A-E3/9AT meet AEC-Q101 requirements for automotive use?
SMCJ130A-E3/9AT itself is not AEC-Q101 qualified; however, Vishay offers functionally identical variants with "HE3" (RoHS-compliant + AEC-Q101) or "HM3" (halogen-free + RoHS + AEC-Q101) suffixes. These qualified versions share the same electrical specs and SMC package but undergo additional reliability testing per JESD22-A108.
What is the thermal resistance of SMCJ130A-E3/9AT, and how does it affect PCB layout?
The SMCJ130A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W. To achieve rated 1500 W pulse performance, Vishay specifies mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal-reducing thermal impedance and preventing junction overheating during surge events.
How does the breakdown voltage tolerance of SMCJ130A-E3/9AT impact system design margin?
The SMCJ130A-E3/9AT exhibits a guaranteed breakdown voltage (VBR) range of 144 V to 159 V at 1 mA test current. This ±5.5 % tolerance ensures ≥11 % headroom above its 130 V standoff voltage (VWM), allowing safe operation under normal conditions while guaranteeing turn-on before damaging overvoltage occurs during transients.
