Product details
Overview
1.5SMC13CA-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 13 V breakdown voltage (VBR min/max = 12.4 V / 13.7 V), 11.1 V standoff voltage (VWM), clamps to ≤18.2 V at 82.4 A peak pulse current (10/1000 μs), and delivers 1500 W peak pulse power. It is used in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the 1.5SMC13CA-E3/9AT datasheet, 1.5SMC13CA-E3/9AT pinout, 1.5SMC13CA-E3/9AT application, or 1.5SMC13CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, SMC (DO-214AB) package compatibility, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B for protector classification.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection against voltage transients regardless of polarity-ideal for AC-coupled or floating signal paths. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5 μA at VWM), while the 10/1000 μs waveform rating reflects real-world lightning and inductive-switching surge profiles.
The device exhibits fast response time (<1.0 ns), low dynamic impedance (incremental surge resistance), and meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C. Its thermal design supports operation from −65 °C to +150 °C junction temperature, with derating above 25 °C ambient per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA test current - defines precise voltage threshold where avalanche conduction begins in either direction |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage; sets safe margin below breakdown |
| VC @ IPPM | ≤18.2 V at 82.4 A (10/1000 μs) - clamping voltage seen by protected circuit during worst-case surge event |
| PPPM | 1500 W - peak transient power handling capacity under standardized surge waveform; determines survivability of lightning strikes |
| IPPM | 82.4 A - maximum non-repetitive surge current the device can shunt without failure |
| Junction Temp Range | −65 °C to +150 °C - enables deployment in under-hood automotive, industrial control cabinets, and outdoor telecom enclosures |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case meeting UL 94 V-0 flammability rating; 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 | Transient current entry point (negative polarity) | One terminal of symmetrical avalanche junction; conducts during negative surges relative to cathode reference |
| Cathode | Transient current entry point (positive polarity) | Other terminal of symmetrical avalanche junction; conducts during positive surges relative to anode reference |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses, or ungrounded lines without polarity concerns |
| 1500 W peak pulse power (10/1000 μs) | Withstands high-energy transients common in automotive load-dump and industrial motor switching environments |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes voltage overshoot across protected ICs or MOSFET gates during surge events |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly processes without preconditioning or special handling |
| UL 497B recognized (QVGQ2) | Validates suitability for use in telecom and data-line protector applications requiring safety agency approval |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ESD in engine control units. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector interface to clamp fast-rising transients before they reach sensitive analog front-ends or communication ICs. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V sensor signal conditioning circuits during ISO 7637-2 Pulse 5a events. |

IC Role / Device Role / Timing Role: Final-stage TVS between DC output capacitor and USB/DC barrel jack to protect downstream USB-PD controllers. Use Value: Ensures output remains below 18.2 V during 1.2/50 μs surge events, preventing overvoltage shutdown or damage to connected IoT endpoints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same VBR range (12.4–13.7 V) and bidirectional configuration, but lower PPPM (600 W) and SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for automotive load-dump or industrial 1 kV surge testing | Select when board space is constrained and surge threat level is limited to IEC 61000-4-5 Level 2 (0.5 kV) |
| 1.5KE13CA | Through-hole TO-204AA (DO-41) package; identical electrical specs but incompatible with SMT assembly and higher thermal resistance | Requires manual insertion or wave soldering; not suitable for high-volume automated production or compact PCB layouts | Choose only for legacy repair, prototyping, or applications where reflow compatibility is not required |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CA-E3/9AT offers the optimal balance of 1500 W surge capacity, SMC surface-mount compatibility, and UL 497B recognition-making it the preferred choice for new automotive and industrial designs requiring AEC-Q101 alignment and automated manufacturing readiness.

FAQ
What does the "CA" suffix indicate in 1.5SMC13CA-E3/9AT?
The "CA" suffix in 1.5SMC13CA-E3/9AT denotes a bidirectional configuration-meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional "A" variants, the CA version has no cathode band marking and functions identically whether voltage is applied anode-to-cathode or cathode-to-anode, making it ideal for AC signal lines and floating interfaces.
Is 1.5SMC13CA-E3/9AT AEC-Q101 qualified?
No, 1.5SMC13CA-E3/9AT is not AEC-Q101 qualified. The base part number 1.5SMC13CA uses the "E3" suffix indicating RoHS-compliant commercial grade. AEC-Q101 qualification requires the "HE3" or "HM3" suffix (e.g., 1.5SMC13CAHE3_A), which includes additional stress testing and traceability documentation per automotive standards.
What is the maximum clamping voltage of 1.5SMC13CA-E3/9AT under surge conditions?
The maximum clamping voltage (VC) of 1.5SMC13CA-E3/9AT is 18.2 V, measured at its peak pulse current (IPPM) of 82.4 A using the standardized 10/1000 μs double-exponential waveform. This value represents the highest voltage the protected circuit will experience during a full-rated surge event.
Can 1.5SMC13CA-E3/9AT be used in place of a unidirectional TVS like 1.5SMC13A-E3/9AT?
No-1.5SMC13CA-E3/9AT and 1.5SMC13A-E3/9AT are not interchangeable without circuit review. The "CA" variant is bidirectional with no polarity marking and symmetrical behavior; the "A" variant is unidirectional with a cathode band and conducts only in reverse bias. Substituting one for the other may result in unintended conduction or failed protection in DC-biased applications.
What does the "/9AT" in 1.5SMC13CA-E3/9AT signify?
The "/9AT" suffix in 1.5SMC13CA-E3/9AT specifies the packaging format: 13-inch diameter plastic tape and reel, with 3500 units per reel. This contrasts with "/57T", which denotes a 7-inch reel containing 850 units. Both formats use the same E3 RoHS-compliant commercial-grade device die and SMC (DO-214AB) package.
