Product details
Overview
1.5SMC13CA-M3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V breakdown voltage (VBR = 12.4–13.7 V at IT = 1.0 mA), 11.1 V stand-off voltage (VWM), and clamps to ≤18.2 V at 82.4 A peak pulse current (10/1000 µs), delivering 1500 W peak pulse power for lightning and inductive-switching surge suppression in automotive sensor interfaces.
For engineers reviewing the 1.5SMC13CA-M3/9AT datasheet, 1.5SMC13CA-M3/9AT pinout, 1.5SMC13CA-M3/9AT application, or 1.5SMC13CA-M3/9AT equivalent, this device serves as a halogen-free, RoHS-compliant, surface-mount TVS with MSL Level 1 rating, low incremental surge resistance, and AEC-Q101 qualification readiness - critical for high-reliability industrial and automotive ESD/transient protection design.
Technical Context
The 1.5SMC13CA-M3/9AT operates bidirectionally with symmetrical clamping behavior in both polarities, enabling single-device protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMC package supports automated placement and meets UL 94 V-0 flammability requirements.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, with maximum junction temperature rated at +150 °C. It sustains repetitive 10/1000 µs pulses at 0.01% duty cycle and derates linearly above TA = 25 °C per Figure 2, making it suitable for thermally constrained PCB layouts with minimal copper pad area (0.31" × 0.31").
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1.0 mA - defines reliable conduction onset under transient stress |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 µA |
| VC @ IPPM | ≤18.2 V at 82.4 A (10/1000 µs) - clamping voltage limiting downstream IC stress during surge events |
| PPPM | 1500 W - peak pulse power handling capability for lightning-induced transients (IEC 61000-4-5) |
| IPPM | 82.4 A - maximum non-repetitive surge current supported with specified waveform and mounting |
| TJ max. | +150 °C - enables operation in under-hood automotive or industrial environments |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 3.2 mm min. creepage and 2.06 mm height |
Pinout & Package
SMC (DO-214AB) package: molded plastic case with matte tin-plated leads, compliant with J-STD-002 and JESD 22-B102 solderability standards. Bidirectional construction means no polarity marking; terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; forms one side of symmetrical clamping path |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; completes bidirectional clamping loop with Anode |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, RS-485), and ungrounded interfaces without polarity constraints |
| 1500 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive applications |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes voltage overshoot across protected circuitry, reducing risk of latch-up or gate oxide damage in downstream MOSFETs/ICs |
| Halogen-free, RoHS-compliant (M3 suffix) | Supports environmental compliance for global OEM programs and eliminates corrosive decomposition products under fault conditions |
| MSL Level 1 (260 °C peak reflow) | Allows standard lead-free reflow assembly without moisture sensitivity concerns or baking requirements |
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 |
|---|---|---|---|
| SMBJ13CA | Same VBR range but lower PPPM = 600 W; SMB package (smaller footprint, higher RθJA = 90 °C/W) | Limited to lower-energy transients (e.g., ESD-only); unsuitable for lightning-level surges in outdoor equipment | Select when board space is constrained and surge threat level is Class 2 or lower per IEC 61000-4-5 |
| 1.5KE13CA | Through-hole DO-201 package; identical electrical specs but larger size and manual assembly requirement | Used where legacy through-hole manufacturing or higher mechanical robustness (vibration/shock) is prioritized over SMT density | Choose for repairability, high-vibration environments, or compatibility with existing through-hole BOMs |
Compared with 1.5SMC13CA-M3/9AT, SMBJ13CA trades surge capacity for compactness, while 1.5KE13CA retains full electrical performance but sacrifices SMT automation and thermal efficiency - making the 1.5SMC13CA-M3/9AT optimal for high-volume, high-reliability surface-mount designs requiring 1500 W protection.

FAQ
What does the "CA" suffix indicate in 1.5SMC13CA-M3/9AT?
The "CA" suffix in 1.5SMC13CA-M3/9AT denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression for both positive and negative polarity surges. Unlike unidirectional variants (e.g., 1.5SMC13A), the 1.5SMC13CA-M3/9AT has no cathode marking and functions identically in either direction - essential for protecting AC-coupled or differential signal paths such as CAN bus or RS-485 lines.
Is 1.5SMC13CA-M3/9AT AEC-Q101 qualified?
The base 1.5SMC13CA-M3/9AT is halogen-free and RoHS-compliant but not AEC-Q101 qualified by default. Vishay offers AEC-Q101 versions under ordering codes HM3_X (e.g., 1.5SMC13CAHM3_A/I), where "_A" denotes qualification for devices up to 220 V VWM. For automotive use requiring qualification, specify the HM3_X variant - the 1.5SMC13CA-M3/9AT itself meets all electrical and mechanical specs needed for qualification but lacks the certified test report.
What is the maximum clamping voltage of 1.5SMC13CA-M3/9AT under surge conditions?
The maximum clamping voltage (VC) of 1.5SMC13CA-M3/9AT is 18.2 V when subjected to its rated peak pulse current of 82.4 A with a 10/1000 µs waveform. This value is measured under standardized test conditions (mounted on 0.31" × 0.31" copper pads) and represents the upper limit of voltage seen by protected circuitry during worst-case surge events - critical for ensuring compatibility with 12 V systems and downstream 3.3 V/5 V ICs.
Can 1.5SMC13CA-M3/9AT be used in place of a unidirectional TVS like 1.5SMC13A?
No - 1.5SMC13CA-M3/9AT cannot directly replace 1.5SMC13A in circuits requiring unidirectional conduction, such as DC power rail protection with polarity-sensitive grounding. The 1.5SMC13CA-M3/9AT is bidirectional and lacks a defined cathode; using it in place of a unidirectional device may cause unintended conduction during normal reverse-bias operation. Always match device polarity to circuit topology: use 1.5SMC13A for DC rails and 1.5SMC13CA-M3/9AT for AC, differential, or floating signal lines.
What is the thermal resistance of 1.5SMC13CA-M3/9AT, and how does it affect layout?
The 1.5SMC13CA-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W. These values assume the recommended 0.31" × 0.31" copper pad per terminal. To maintain safe junction temperatures under repetitive surges, PCB layout must provide adequate copper area and avoid excessive trace length between the 1.5SMC13CA-M3/9AT and ground/power planes - insufficient copper increases effective RθJA, risking thermal runaway during sustained transient activity.
