Product details
Overview
1.5SMC130CAHE3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 130 V standoff voltage (VWM), 1500 W peak pulse power rating (10/1000 μs), clamping voltage of 219 V at 8.4 A, and operates across -65 °C to +150 °C. It is used to protect automotive sensor interfaces, industrial I/O ports, and telecom line cards against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC130CAHE3/9AT datasheet, 1.5SMC130CAHE3/9AT pinout, 1.5SMC130CAHE3/9AT application, or 1.5SMC130CAHE3/9AT equivalent, this device delivers verified bidirectional clamping performance, AEC-Q101 qualification for automotive use, RoHS-compliant matte tin terminations, and SMC (DO-214AB) package compatibility with automated placement systems.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01% duty cycle. Its symmetrical breakdown behavior ensures identical clamping in both polarities, eliminating polarity concerns in AC-coupled or floating signal paths.
The device is rated for 1500 W peak pulse power with derating above 25 °C (RθJA = 75 °C/W), supports 200 A non-repetitive forward surge current (unidirectional mode only), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak temperature - enabling robust integration into high-reliability PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed symmetric breakdown threshold in both directions; ensures predictable turn-on. |
| VC (Clamping Voltage) | 219 V at IPPM = 8.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains high-energy transients without failure; validated per Fig. 1 in datasheet with 0.31" × 0.31" copper pads. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current; avoids loading sensitive analog or low-power circuits. |
| TJ max | +150 °C - Enables operation in under-hood automotive or industrial environments without thermal derating penalties. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD; suffix HE3 confirms qualification. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal 1 | One side of symmetrical PN junction; connects to either side of protected line (e.g., RS-485 A/B, CAN H/L, or AC input). |
| Cathode | Terminal 2 | Other side of symmetrical PN junction; forms bidirectional clamping path with Anode; no band marking required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both polarities - eliminates need for polarity-aware layout in differential or AC-coupled lines. |
| 1500 W peak pulse rating | Withstands IEC 61000-4-5 Level 4 surges (4 kV, 2 Ω source) without degradation when mounted per recommended pad layout. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, ADAS sensors, and infotainment power rails. |
| MSL Level 1 moisture sensitivity | Compatible with standard SMT reflow profiles up to 260 °C peak - no baking or special handling required. |
| Glass-passivated junction | Enhances long-term stability and reduces parameter drift under thermal cycling and humidity exposure. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM (111 V) and VC (219 V), but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 85 °C/W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive under-hood locations requiring 1500 W. | Select when board space is constrained and surge threat level is ≤600 W; verify thermal margin with reduced copper area. |
| 1.5KE130CA | Same electrical specs but axial-leaded DO-15 package; not SMT-compatible; higher parasitic inductance limits high-speed surge response. | Requires through-hole assembly; incompatible with automated SMT lines; not suitable for high-frequency transient suppression. | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs performance and manufacturability trade-offs. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHE3/9AT uniquely combines 1500 W surge capability, AEC-Q101 qualification, SMC package manufacturability, and bidirectional symmetry - making it the preferred choice for production automotive and industrial SMT designs demanding full IEC 61000-4-5 Level 4 compliance.

FAQ
What is the clamping voltage of the 1.5SMC130CAHE3/9AT under a 10/1000 μs surge?
The 1.5SMC130CAHE3/9AT clamps to a maximum of 219 V at 8.4 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured with the device mounted on 0.31" × 0.31" copper pads per Figure 1 in the Vishay datasheet 88303, and represents the upper limit of voltage imposed on protected circuitry during surge events.
Is the 1.5SMC130CAHE3/9AT suitable for automotive applications?
Yes, the 1.5SMC130CAHE3/9AT is AEC-Q101 qualified (confirmed by the HE3 suffix) and rated for operation from -65 °C to +150 °C. It has passed automotive-specific stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - making it appropriate for engine control units, body electronics, and ADAS sensor modules.
Does the 1.5SMC130CAHE3/9AT have polarity markings on the package?
No, the 1.5SMC130CAHE3/9AT is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows connection in either orientation across protected lines - simplifying layout and eliminating risk of reverse installation in differential or AC-coupled circuits.
What is the maximum reverse leakage current for the 1.5SMC130CAHE3/9AT at its stand-off voltage?
The 1.5SMC130CAHE3/9AT exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated stand-off voltage (VWM) of 111 V, measured at 25 °C. This ultra-low leakage ensures minimal impact on high-impedance sensor inputs, battery-powered circuits, and precision analog signal paths.
Can the 1.5SMC130CAHE3/9AT be used in place of a unidirectional TVS like the 1.5SMC130AHE3/9AT?
No - the 1.5SMC130CAHE3/9AT is bidirectional and lacks polarity; substituting it for the unidirectional 1.5SMC130AHE3/9AT would compromise protection in DC-biased circuits where only one polarity of surge is expected. The unidirectional version provides lower forward voltage drop and tighter leakage specs in single-direction applications.
