Product details
Overview
1.5SMC130CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the 1.5SMC130CA-E3/9AT datasheet, 1.5SMC130CA-E3/9AT pinout, 1.5SMC130CA-E3/9AT application, or 1.5SMC130CA-E3/9AT equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, MSL Level 1 moisture sensitivity, and AEC-Q101 qualification readiness via HE3/HM3 variants.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping behavior during positive and negative transients - critical for AC-coupled or floating signal lines. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The device uses the SMC (DO-214AB) package with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102, supporting automated placement and reflow up to 260 °C peak. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), enabling effective power dissipation in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 124–137 V at 1 mA - sharp, repeatable avalanche onset ensuring predictable transient response. |
| VC (Clamping) | 179 V at 8.4 A (10/1000 μs) - limits voltage seen by downstream ICs during ESD or lightning-induced surges. |
| PPPM | 1500 W - handles high-energy transients such as ISO 7637-2 Pulse 5a without degradation. |
| ID (Leakage) | 1.0 μA max at VWM - negligible standby current, preserving low-power system integrity. |
| TJ max | +150 °C - supports operation in under-hood automotive and industrial environments. |
| Package | SMC (DO-214AB) - industry-standard 2-pin surface-mount outline with 8.0 mm × 8.0 mm copper pad thermal design. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case meeting UL 94 V-0 flammability rating; terminals are matte tin-plated, solderable per J-STD-002; polarity unmarked for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Conducts during negative surges; symmetrical with cathode for bidirectional clamping. |
| Cathode | Transient current entry (positive half-cycle) | Conducts during positive surges; functionally identical to anode in CA-series devices. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout in differential or AC signal paths. |
| 1500 W peak pulse power | Sustains high-energy transients (e.g., ISO 16750-2 Load Dump simulations) without failure or parameter shift. |
| MSL Level 1 rating | Zero floor life limitation - can be stored indefinitely and processed in standard SMT reflow without baking. |
| Glass-passivated junction | Enhances long-term stability of breakdown voltage and leakage under thermal cycling and humidity stress. |
| AEC-Q101 qualification path | HE3/HM3 variants available - enables direct migration to automotive-grade production without redesign. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

IC Role / Device Role / Timing Role: Secondary-side TVS across bulk capacitor to absorb residual energy after MOV-based primary protection. Use Value: Low leakage (<1 μA) avoids capacitor discharge issues; 1500 W rating handles repeated line dips and switch-mode noise bursts. |
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 range, SMB package (smaller footprint, higher RθJA = 110 °C/W) | Preferred where board space is constrained but surge energy is ≤600 W (e.g., USB port protection) | Select when thermal budget allows higher junction temperature rise and peak power demand is moderate. |
| 1.5KE130CA | Through-hole DO-201 package, identical electrical specs, higher mechanical robustness but no SMT compatibility | Suitable for prototyping, high-vibration environments, or legacy through-hole designs | Choose only if SMT assembly is unavailable or mechanical shock resistance outweighs automated manufacturing benefits. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CA-E3/9AT delivers optimal balance of high surge capacity (1500 W), SMT manufacturability, and thermal performance in the widely adopted SMC outline - making it the preferred choice for volume automotive and industrial PCBs requiring AEC-Q101 scalability.

FAQ
What does the "CA" suffix indicate in 1.5SMC130CA-E3/9AT?
The "CA" suffix denotes a bidirectional configuration: the 1.5SMC130CA-E3/9AT provides symmetrical clamping for both positive and negative transients, unlike unidirectional "A" variants. This eliminates polarity concerns during placement and simplifies design for AC-coupled or floating circuits - a key feature confirmed in Vishay's 1.5SMC datasheet revision 09-Mar-2026.
Is 1.5SMC130CA-E3/9AT AEC-Q101 qualified?
No - the 1.5SMC130CA-E3/9AT is RoHS-compliant commercial-grade. However, Vishay offers AEC-Q101-qualified versions under HE3 (RoHS + AEC-Q101) and HM3 (halogen-free + AEC-Q101) suffixes, such as 1.5SMC130CAHE3_A/I. The 1.5SMC130CA-E3/9AT itself is not certified but shares identical electrical and thermal characteristics with qualified variants.
What is the clamping voltage of 1.5SMC130CA-E3/9AT at its rated peak pulse current?
The 1.5SMC130CA-E3/9AT has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current with a 10/1000 μs waveform, as specified in the Electrical Characteristics table (Document Number: 88303, page 2). This value defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can 1.5SMC130CA-E3/9AT be used in place of a unidirectional TVS like 1.5SMC130A-E3/9AT?
No - the 1.5SMC130CA-E3/9AT is bidirectional and lacks polarity marking, while 1.5SMC130A-E3/9AT is unidirectional with cathode band identification. Substitution requires verifying circuit topology: bidirectional use is mandatory for AC signals or floating grounds; unidirectional parts are required for DC-biased lines where reverse conduction must be blocked.
What is the thermal resistance of 1.5SMC130CA-E3/9AT, and how does it affect PCB layout?
The 1.5SMC130CA-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads (RθJL) of 15 °C/W, measured on 8.0 mm × 8.0 mm copper pads per terminal. To maintain reliability under repetitive surges, PCB layout must replicate this pad area - undersized traces or insufficient copper will elevate junction temperature beyond the 150 °C maximum.
