Product details
Overview
1.5SMC130CAHE3_A/I from Vishay General Semiconductor is a bidirectional 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 handling with a 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line cards.
For engineers reviewing the 1.5SMC130CAHE3_A/I datasheet, 1.5SMC130CAHE3_A/I pinout, 1.5SMC130CAHE3_A/I application, or 1.5SMC130CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification for automotive use, SMC (DO-214AB) package thermal performance, and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), but triggers into low-impedance conduction when transient voltage exceeds its breakdown threshold (124–137 V at 1 mA). Its bidirectional architecture ensures symmetrical clamping in both polarities without polarity marking.
Thermally, it uses a glass-passivated junction mounted in an SMC package with RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. It meets J-STD-020 MSL Level 1 and supports reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - maximum continuous reverse voltage before leakage exceeds 1 μA; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 124–137 V at 1 mA - guaranteed voltage range where device transitions from high- to low-impedance state; ensures predictable triggering. |
| VC (Clamping) | 179 V at IPPM = 8.4 A - maximum voltage seen by downstream circuit during 10/1000 μs surge; determines protection margin for 130 V-rated systems. |
| PPPM | 1500 W - peak transient power dissipation capability with standard 10/1000 μs waveform; enables suppression of lightning-induced surges per IEC 61000-4-5. |
| Package | SMC (DO-214AB) - surface-mount package with 8.0 mm × 8.0 mm copper pad thermal footprint; supports automated placement and meets UL 94 V-0 flammability. |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suffix HE3 denotes this qualification. |
| Leakage (ID) | <1 μA at VWM - minimal standby current draw preserves system efficiency and avoids false triggering in low-power circuits. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (negative polarity) | Conducts surge current during negative transients; forms symmetrical clamping path with cathode. |
| Cathode | Transient current entry point (positive polarity) | Conducts surge current during positive transients; paired with anode for full bidirectional protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for polarity-aware layout and enables single-device protection on AC or floating lines. |
| 1500 W peak pulse power | Withstands 10/1000 μs surges up to 8.4 A - meets IEC 61000-4-5 Level 4 (4 kV) requirements when properly laid out. |
| AEC-Q101 qualification | Validated for automotive underhood and infotainment applications - includes HTOL, TC, and ESD testing per AEC standard. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients - improves protection margin for sensitive 130 V rail systems. |
| MSL Level 1 moisture sensitivity | Unlimited floor life at ≤30 °C/60% RH - simplifies manufacturing logistics and eliminates bake requirements pre-reflow. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

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 | Same VWM (111 V) and VC (179 V), but lower PPPM (600 W); SMB package (smaller thermal mass). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load-dump events. | Select when board space is constrained and surge energy is ≤600 W; verify thermal derating for repeated events. |
| 1.5KE130CA | Same electrical specs but axial-leaded DO-201AE package; higher RθJA (~100 °C/W); no AEC-Q101 qualification. | Not suitable for automated SMT assembly or automotive underhood environments; requires manual insertion. | Choose only for prototyping or legacy through-hole designs; avoid for volume production or AEC-compliant systems. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHE3_A/I delivers superior surge endurance (1500 W vs. 600 W/1500 W), AEC-Q101 qualification, and SMT compatibility - making it the preferred choice for automotive and industrial applications demanding repeatable, high-reliability clamping.

FAQ
What is the clamping voltage of the 1.5SMC130CAHE3_A/I at its rated peak pulse current?
The 1.5SMC130CAHE3_A/I has a maximum clamping voltage (VC) of 179 V at its specified peak pulse current (IPPM) of 8.4 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC130CAHE3_A/I maintains this clamping performance across its full operating temperature range (–65 °C to +150 °C).
Is the 1.5SMC130CAHE3_A/I suitable for automotive applications?
Yes, the 1.5SMC130CAHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix, and is explicitly rated for automotive use in underhood and infotainment systems. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling, and ESD per AEC-Q101 Rev D. The 1.5SMC130CAHE3_A/I also meets UL 497B recognition for surge protectors, supporting its deployment in ISO 7637-2 compliant vehicle networks.
What does the "CA" suffix mean in 1.5SMC130CAHE3_A/I?
The "CA" suffix in 1.5SMC130CAHE3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., "A" suffix), the 1.5SMC130CAHE3_A/I has no cathode band marking and exhibits identical breakdown and clamping characteristics in either direction, simplifying PCB layout for AC-coupled or floating signal lines.
What is the thermal resistance of the 1.5SMC130CAHE3_A/I, and how does it affect layout?
The 1.5SMC130CAHE3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay specification 88303. To maintain safe junction temperatures during repetitive surges, designers must ensure adequate copper area and avoid excessive trace length between the 1.5SMC130CAHE3_A/I and ground/power planes.
How does the 1.5SMC130CAHE3_A/I compare to unidirectional versions like 1.5SMC130AHE3_A/I?
The 1.5SMC130CAHE3_A/I differs from unidirectional 1.5SMC130AHE3_A/I in polarity behavior: the "CA" version clamps symmetrically in both directions with no cathode marking, while the "A" version conducts only in reverse bias and requires correct orientation. Electrically, their VWM (111 V), VBR (124–137 V), and VC (179 V) are identical, but the 1.5SMC130CAHE3_A/I supports AC signal lines and floating buses where polarity is undefined or alternating.
