Product details
Overview
1.5SMC130CAHE3/57T 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 AEC-Q101 qualification for automotive use - deployed in CAN bus interfaces, sensor supply rails, and industrial I/O protection.
For engineers reviewing the 1.5SMC130CAHE3/57T datasheet, 1.5SMC130CAHE3/57T pinout, 1.5SMC130CAHE3/57T application, or 1.5SMC130CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, low leakage (<1 μA at 111 V), thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B and AEC-Q101 for harsh-environment reliability.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential lines without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the SMC package supports automated placement and meets MSL level 1 (260 °C reflow).
The device delivers 1500 W peak pulse power under standardized 10/1000 μs waveform conditions, with clamping voltage tightly controlled at 179 V at rated IPPM. Thermal derating begins above 25 °C ambient per Figure 2, and junction temperature is limited to 150 °C maximum - critical for sustained operation in engine control units and motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - Maximum continuous reverse voltage before conduction; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 124–137 V at 1 mA - Voltage range where avalanche breakdown initiates reliably; ensures predictable turn-on during transients. |
| VC (Clamping) | 179 V at 8.4 A - Maximum voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM | 1500 W - Peak transient energy absorption capacity; enables robust protection against lightning-induced surges and inductive switching spikes. |
| IPPM | 8.4 A - Peak pulse current corresponding to VC; used to size PCB trace width and verify system-level surge compliance. |
| TJ max | 150 °C - Maximum allowable junction temperature; sets thermal design limits for board layout and heatsinking. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs power dissipation limits in standard pad layout (8.0 mm × 8.0 mm copper). |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional - no polarity marking; symmetrical terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals function identically; surge current flows bidirectionally between them - no cathode band or polarity identification required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals, differential buses (e.g., RS-485, CAN), and ungrounded lines without external polarity management. |
| AEC-Q101 qualification | Validated for automotive applications including powertrain and body electronics - supports long-term reliability under thermal cycling and vibration. |
| 1500 W peak pulse rating | Meets IEC 61000-4-5 Level 4 (4 kV line-to-line) surge immunity requirements when properly laid out on PCB. |
| Low leakage & tight VBR tolerance | <1 μA at 111 V and ±5% breakdown spread ensure minimal standby power loss and consistent trigger behavior across production lots. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile compatibility (peak 260 °C), eliminating bake-out requirements in manufacturing. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |

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/VC, but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA = 110 °C/W). | Suitable for space-constrained consumer electronics with lower surge exposure; not recommended for automotive or industrial mains-connected systems. | Select when board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2. |
| 1.5KE130CA | Same electrical specs but axial DO-15 package; higher mounting thermal resistance and manual assembly requirement. | Used in legacy industrial controls and repair kits where through-hole compatibility is mandatory; lacks AEC-Q101 qualification. | Choose only for retrofit or cost-sensitive non-automotive applications where SMT is not feasible. |
Compared with SMBJ130CA and 1.5KE130CA, the 1.5SMC130CAHE3/57T offers superior surge handling (1500 W vs. 600 W or 1500 W with inferior thermal performance), AEC-Q101 validation, and optimized SMC package for automated high-volume production - making it the preferred choice for new automotive and industrial designs.

FAQ
What is the clamping voltage of the 1.5SMC130CAHE3/57T under a 10/1000 μs surge?
The 1.5SMC130CAHE3/57T clamps to a maximum of 179 V at 8.4 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC130CAHE3/57T suitable for automotive applications?
Yes, the 1.5SMC130CAHE3/57T carries AEC-Q101 qualification (indicated by the "HE3" suffix), confirming its suitability for automotive environments including powertrain, chassis, and body electronics. It meets requirements for thermal cycling, humidity bias, and mechanical shock - validated per the full AEC-Q101 test suite and documented in Vishay's qualification reports.
Does the 1.5SMC130CAHE3/57T have polarity markings?
No, the 1.5SMC130CAHE3/57T is a bidirectional TVS diode and has no polarity markings. Its symmetrical construction means both terminals are functionally identical - no cathode band or anode indicator is present, simplifying layout and eliminating orientation errors during automated placement.
What is the maximum operating junction temperature for the 1.5SMC130CAHE3/57T?
The maximum operating junction temperature for the 1.5SMC130CAHE3/57T is 150 °C, as specified in the "Maximum Ratings" table of Vishay document 88303. This limit governs thermal design margins and must be respected during worst-case power dissipation analysis - especially under repetitive surge conditions or elevated ambient temperatures.
How does the 1.5SMC130CAHE3/57T differ from unidirectional variants like 1.5SMC130AHE3/57T?
The 1.5SMC130CAHE3/57T is bidirectional (denoted by "CA"), providing symmetrical clamping for AC or differential signals, whereas 1.5SMC130AHE3/57T is unidirectional ("A") with a cathode band and forward conduction path. The "CA" version supports applications like RS-485 or CAN where polarity reversal occurs, while the "A" variant is used for DC rail protection with defined ground reference.
