Product details
Overview
1.5SMC130CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on signal and power lines. It features 130 V standoff voltage (VWM), 1500 W peak pulse power (10/1000 μs), clamping voltage of 179 V at 8.4 A, and operates across -65 °C to +150 °C junction temperature. It is widely used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC130CA-E3/57T datasheet, 1.5SMC130CA-E3/57T pinout, 1.5SMC130CA-E3/57T application, or 1.5SMC130CA-E3/57T equivalent, key selection criteria include bidirectional clamping behavior, low incremental surge resistance, MSL Level 1 moisture sensitivity, RoHS-compliant matte tin plating, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This device functions as a voltage-clamped crowbar during transients-responding in <1 ps to overvoltage events induced by inductive switching or lightning surges. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at 111 V), while the bidirectional architecture eliminates polarity concerns in AC-coupled or differential signal paths.
The 1.5SMC130CA-E3/57T delivers 1500 W peak pulse power under standardized 10/1000 μs waveform conditions, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads). It meets AEC-Q101 qualification when ordered with HE3/HM3 suffixes, though the E3/57T variant is commercial-grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed breakdown range ensures predictable turn-on threshold under transient stress. |
| VC (Clamping Voltage) | 179 V at 8.4 A IPPM - Peak voltage seen by protected circuit during 1500 W surge; critical for downstream IC survival. |
| PPPM | 1500 W - Peak pulse power handling per 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 Level 4 surges. |
| Package | SMC (DO-214AB) - Surface-mount package with 8.0 mm × 8.0 mm copper pad requirement; supports automated assembly and thermal dissipation. |
| Operating Temperature | -65 °C to +150 °C - Wide junction temperature range supports under-hood automotive and industrial environments. |
| RoHS Compliance | E3 suffix - Lead-free, RoHS-compliant matte tin plating; qualified per J-STD-002 and JESD 22-B102 solderability standards. |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case meeting UL 94 V-0 flammability rating; terminals are matte tin plated, unmarked for bidirectional polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | One terminal of symmetrical PN junction; accepts surge current regardless of polarity. |
| Cathode | Transient current exit (bidirectional) | Second terminal of symmetrical structure; completes low-impedance path to ground or return rail during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection on AC lines, differential buses (e.g., RS-485), or ungrounded sensor outputs without polarity constraints. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 kA short-circuit without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage stress on downstream components-critical for 130 V-rated systems like 110 VAC auxiliary supplies. |
| MSL Level 1 rating | Allows unlimited floor life and reflow at peak 260 °C; eliminates baking requirements prior to assembly. |
| Glass-passivated junction | Ensures long-term stability of breakdown voltage and leakage current under thermal cycling and humidity exposure. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Lower PPPM (600 W), same VWM/VC specs, SMB package (smaller footprint, higher RθJA = 110 °C/W) | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable where 1500 W margin is required. | Select when board space is constrained and surge threat level is moderate; verify thermal derating at elevated ambient. |
| 1.5KE130CA | Same electrical specs but DO-201AE axial package; higher mounting inductance, manual assembly only | Not suitable for high-speed SMT lines; introduces parasitic inductance that degrades clamping response above 10 MHz. | Choose only for legacy through-hole designs or prototyping; avoid in production-grade SMT systems requiring automated placement. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CA-E3/57T provides optimal balance of high-power surge handling, SMT manufacturability, and thermal performance in compact form-making it preferred for volume automotive and industrial applications demanding repeatable 1500 W protection.

FAQ
What is the clamping voltage of the 1.5SMC130CA-E3/57T under maximum surge conditions?
The 1.5SMC130CA-E3/57T has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage the protected circuit will experience during a 1500 W transient event. The 1.5SMC130CA-E3/57T maintains this clamping performance due to its low incremental surge resistance and glass-passivated junction.
Is the 1.5SMC130CA-E3/57T suitable for automotive applications?
The 1.5SMC130CA-E3/57T is RoHS-compliant and manufactured to commercial-grade specifications. While it shares the same die and package as AEC-Q101-qualified variants (e.g., 1.5SMC130CAHE3_A), the E3/57T suffix indicates non-automotive qualification. For production automotive use, engineers must select the HE3 or HM3 suffix versions. The 1.5SMC130CA-E3/57T remains appropriate for automotive prototyping, aftermarket systems, or non-safety-critical subsystems where formal qualification is not mandated.
How does the bidirectional design of the 1.5SMC130CA-E3/57T affect PCB layout?
The 1.5SMC130CA-E3/57T has no polarity marking and functions identically in either orientation, simplifying PCB layout by eliminating cathode/anode routing constraints. This allows direct placement across differential pairs (e.g., RS-485 A/B), AC signal lines, or ungrounded power rails without directional verification. Layout best practices still require symmetric trace lengths and minimum 8.0 mm × 8.0 mm copper pads per terminal to maintain specified thermal and surge performance. The 1.5SMC130CA-E3/57T benefits from this symmetry in both layout efficiency and functional robustness.
What is the maximum steady-state power dissipation of the 1.5SMC130CA-E3/57T?
The 1.5SMC130CA-E3/57T has a maximum steady-state power dissipation (PD) of 6.5 W when mounted on an infinite heatsink at TA = 50 °C. In typical PCB applications with 8.0 mm × 8.0 mm copper pads per terminal, derating applies above 25 °C ambient-per Figure 2 in the Vishay datasheet (Document Number: 88303). Continuous power handling is limited by junction temperature; the 1.5SMC130CA-E3/57T must not exceed 150 °C TJ, and its RθJA of 75 °C/W governs thermal design margins.
Does the 1.5SMC130CA-E3/57T meet any safety certifications?
Yes-the 1.5SMC130CA-E3/57T carries Underwriters Laboratories (UL) recognition under file number E136766 for both unidirectional and bidirectional configurations, compliant with UL 497B for signal circuit protectors. It also meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity test requirements when applied per recommended layout guidelines. These certifications apply to the device itself; system-level compliance requires full end-equipment validation. The 1.5SMC130CA-E3/57T's UL listing confirms its suitability for safety-critical protection roles in certified end products.
