Product details
Overview
SMBJ130A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 130 V stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMBJ130A-E3/52 datasheet, SMBJ130A-E3/52 pinout, SMBJ130A-E3/52 application, or SMBJ130A-E3/52 equivalent, this device is selected for robust overvoltage protection in DC power rails, industrial I/O interfaces, and automotive subsystems where fast response (<1 ps), low clamping ratio, and AEC-Q101-compliant reliability are required.
Technical Context
The SMBJ130A-E3/52 operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling precise clamping during transient events.
It delivers 209 V clamping at 2.9 A IPPM under 10/1000 µs waveform, with thermal resistance RθJA = 100 °C/W and operating junction temperature range of –55 °C to +150 °C. Polarity is marked by cathode band; no marking on bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 130 V - Maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 144–159 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients |
| VC (Clamping) | 209 V at 2.9 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components |
| PPPM | 600 W - Surge energy handling capability with standard 10/1000 µs waveform; supports repetitive 0.01% duty cycle |
| IPPM | 2.9 A - Peak surge current corresponding to VC; used to size PCB trace width and verify layout survivability |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs heatsinking requirements |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to lower-potential side of protected line (e.g., ground or return path); defines polarity-sensitive placement |
| Cathode | Avalanche conduction node / Clamping output | Connected to higher-potential side (e.g., VIN, signal line); conducts surge current to ground when VREV > VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Handles high-energy transients without degradation-validated per IEC 61000-4-5 Level 4 (4 kV) test conditions |
| Fast response time (<1 ps) | Clamps within picoseconds of overvoltage onset-prevents latch-up or gate oxide damage in MOSFETs and ICs |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes voltage overshoot across protected node-critical for 130 V-rated systems with tight margin |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT assembly-no moisture sensitivity concerns or baking required |
| AEC-Q101 qualified option available | HE3 suffix variant meets automotive-grade reliability for engine control, ADAS, and body electronics |
Applications
| Industrial Motor Drive I/O Protection | Automotive Power Distribution Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA-E3/52 | Bidirectional variant; symmetric VBR (144–159 V) in both polarities; same VC and PPPM | Required for AC-coupled signal lines or differential buses (e.g., RS-485, CAN) where polarity reversal occurs | Select when protecting bidirectional data paths or floating references; not interchangeable without circuit review |
| SMAJ130A-E3/52 | Lower PPPM (400 W); same VWM/VBR but higher VC (230 V); SMA (DO-214AC) package with smaller footprint | Suitable for space-constrained consumer designs with lower surge exposure (IEC 61000-4-2 Level 3 only) | Choose for cost-sensitive, non-automotive applications where 600 W headroom is unnecessary |

FAQ
What is the maximum clamping voltage of SMBJ130A-E3/52 under standard test conditions?
The SMBJ130A-E3/52 has a maximum clamping voltage (VC) of 209 V at 2.9 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the highest voltage imposed on the protected circuit during surge conduction-critical for verifying compatibility with downstream component voltage ratings.
Is SMBJ130A-E3/52 RoHS-compliant and halogen-free?
Yes, SMBJ130A-E3/52 carries the "E3" suffix, indicating it is RoHS-compliant and meets commercial-grade specifications. It is not halogen-free; for halogen-free compliance, the "M3" suffix variant (e.g., SMBJ130A-M3/52) must be selected per Vishay's ordering matrix.
Can SMBJ130A-E3/52 be used in automotive applications?
The base SMBJ130A-E3/52 is commercial-grade; however, the AEC-Q101 qualified version-SMBJ130AHE3_B/H-is available for automotive use. That variant undergoes extended stress testing per AEC-Q101 and is designated for engine control, body electronics, and ADAS subsystems where qualification is mandatory.
What is the thermal resistance and how does it affect PCB layout for SMBJ130A-E3/52?
SMBJ130A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under worst-case 5.0 W steady-state dissipation, designers must ensure adequate copper area and avoid thermal bottlenecks near the SMB (DO-214AA) body.
How does the unidirectional configuration of SMBJ130A-E3/52 impact circuit placement?
The SMBJ130A-E3/52 is unidirectional and marked with a cathode band; it must be oriented with cathode toward the higher-potential node (e.g., VIN) and anode toward ground or return. Incorrect orientation prevents clamping during positive transients and may cause catastrophic failure under reverse bias beyond VWM.
