Product details
Overview
SMBG130A-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of DC power rails and signal lines. 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 - deployed in automotive power electronics, industrial sensor interfaces, and telecom line protection.
For engineers reviewing the SMBG130A-E3/52 datasheet, SMBG130A-E3/52 pinout, SMBG130A-E3/52 application, or SMBG130A-E3/52 equivalent, key selection criteria include clamping performance under 2.9 A surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification for automotive use, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a shunt-type overvoltage protector, triggering when reverse voltage exceeds its breakdown threshold to clamp transients and divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage and fast response (<1 ns), while low incremental surge resistance minimizes voltage overshoot during high-current events.
Rated for -55 °C to +150 °C junction temperature, it supports high-reliability applications requiring MSL Level 1 moisture sensitivity compliance and 260 °C lead-free reflow compatibility. The device is not intended for continuous forward conduction but delivers 100 A non-repetitive surge current capability (8.3 ms half-sine) in unidirectional configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction. |
| VC @ IPPM | 209 V at 2.9 A - Clamping voltage under standardized 10/1000 µs surge; determines protected circuit's peak stress level. |
| PPPM | 600 W - Peak pulse power handling per JEDEC JESD22-A114; validates survivability against lightning-induced surges. |
| IFSM | 100 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports high-energy load dump events. |
| TJ max | +150 °C - Maximum junction temperature enables operation in under-hood automotive or high-ambient industrial environments. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: SMBG (DO-215AA), surface-mount, low-profile gull-wing leaded case with matte tin-plated terminals solderable per J-STD-002 and JESD22-B102; meets UL 94 V-0 flammability rating and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to system ground or low-side reference; completes shunt path during transient suppression. |
| Cathode | Reverse-biased terminal / Clamping node | Marked with band; connected to protected line (e.g., 130 V supply rail); conducts avalanche current when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable leakage current (<1.0 µA at VWM) and long-term parameter consistency across temperature and life cycles. |
| 600 W 10/1000 µs pulse rating | Validates robustness against IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) in properly laid-out PCBs with 5.0 mm × 5.0 mm pads. |
| AEC-Q101 qualification | Confirms suitability for automotive powertrain, body control, and ADAS modules where failure modes must meet stringent reliability thresholds. |
| MSL Level 1, 260 °C peak | Enables single-pass lead-free reflow without preconditioning; eliminates moisture-related popcorning risk during manufacturing. |
| Low-profile SMBG package | 0.235" × 0.130" footprint (5.97 mm × 3.30 mm) saves board space vs. larger DO-214AB (SMC) while maintaining thermal performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 | Same VWM/VBR/VC, but SMB (DO-214AA) package; 100 W lower PPPM (500 W vs. 600 W). | Limited to lower-energy transients; less margin for IEC 61000-4-5 Level 4 compliance in high-inductance layouts. | Select when board space allows larger SMB footprint and surge energy is constrained to <500 W. |
| SMCJ130A-E3/52 | Same electrical specs, but SMC (DO-214AB) package; 1500 W PPPM, higher thermal mass, larger 7.11 mm × 6.22 mm footprint. | Better for high-repetition surges or elevated ambient temperatures (>105 °C); requires more PCB area. | Choose for mission-critical industrial systems needing extended surge endurance and derated thermal performance. |
Compared with SMBJ130A-E3/52 and SMCJ130A-E3/52, SMBG130A-E3/52 delivers optimal balance of 600 W surge capacity, AEC-Q101 qualification, and compact SMBG footprint - making it preferred for space-constrained automotive and industrial modules where both reliability and board area are critical.

FAQ
What is the clamping voltage of SMBG130A-E3/52 at its rated peak pulse current?
The SMBG130A-E3/52 has a maximum clamping voltage (VC) of 209 V at its specified peak pulse current (IPPM) of 2.9 A, measured using the standard 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2. The SMBG130A-E3/52 maintains this clamping performance across its full operating temperature range.
Is SMBG130A-E3/52 suitable for automotive applications?
Yes, SMBG130A-E3/52 is AEC-Q101 qualified per the Vishay datasheet, confirming its reliability for automotive use cases including engine control modules, body electronics, and ADAS sensor interfaces. It meets requirements for temperature cycling, high-temperature reverse bias, and ESD robustness. The SMBG130A-E3/52 also complies with MSL Level 1 and supports lead-free reflow up to 260 °C - essential for modern automotive PCB assembly.
What does the "E3/52" suffix indicate in SMBG130A-E3/52?
The "E3" suffix denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads, while "/52" specifies packaging in 7-inch diameter plastic tape and reel containing 750 units. This format aligns with Vishay's ordering nomenclature in the datasheet's "Ordering Information" section (page 3). The SMBG130A-E3/52 is not AEC-Q101 qualified in the E3 variant - only HE3/HM3 variants carry that qualification; users requiring automotive grade must verify part number suffix accordingly.
How does SMBG130A-E3/52 differ from bidirectional TVS diodes like SMBG130CA?
SMBG130A-E3/52 is unidirectional and features a cathode band marking, intended for DC rail protection where polarity is fixed. In contrast, SMBG130CA is bidirectional with no polarity marking and symmetric clamping in both directions - suited for AC lines or differential signal pairs. Electrical parameters such as VWM and VC are identical, but SMBG130A-E3/52 supports 100 A forward surge current (IFSM), whereas SMBG130CA does not specify IFSM due to symmetrical structure. The SMBG130A-E3/52 is not interchangeable with SMBG130CA without circuit redesign.
What PCB pad layout is recommended for optimal thermal and surge performance of SMBG130A-E3/52?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area per terminal for SMBG130A-E3/52 to achieve rated 600 W pulse power and proper thermal dissipation. The datasheet (page 2) states that derating applies above TA = 25 °C per Figure 2, and thermal resistance is RθJA = 100 °C/W under these conditions. Using smaller pads reduces surge capability and risks solder joint failure; the SMBG130A-E3/52 must be mounted per the DO-215AA outline on page 5 to ensure mechanical stability and thermal path integrity.
