Product details
Overview
1.5SMC13CA-E3/57T 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), 1500 W peak pulse power (10/1000 µs), clamping voltage of 18.2 V at 82.4 A, and operates across -65 °C to +150 °C. It is widely deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC13CA-E3/57T datasheet, 1.5SMC13CA-E3/57T pinout, 1.5SMC13CA-E3/57T application, or 1.5SMC13CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, SMC (DO-214AB) package compatibility, low incremental surge resistance, and AEC-Q101 qualification readiness via HE3 suffix variants.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and stable clamping under repetitive transients. Its symmetrical I-V characteristics enable identical protection in both polarities without polarity marking on the case.
Rated for 1500 W peak pulse power with 10/1000 µs waveform and 0.01% duty cycle, it delivers consistent clamping up to 18.2 V while limiting peak current to 82.4 A - validated under standard 8.0 mm × 8.0 mm copper pad mounting per JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA test current - defines reliable conduction onset for transient suppression |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5 µA |
| VC @ IPPM | 18.2 V at 82.4 A - clamped voltage during worst-case 1500 W surge, critical for downstream IC survivability |
| PPPM | 1500 W (10/1000 µs waveform) - peak surge energy handling capacity under standardized lightning/inductive-switching stress |
| TJ max | +150 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |
| RoHS | Compliant (E3 suffix) - lead-free matte tin terminations, J-STD-002 solderable, MSL Level 1 (260 °C peak) |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case with UL 94 V-0 flammability rating; terminals are matte tin-plated, solderable per J-STD-002; no polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode (bidirectional) | One side of symmetrical PN junction - connects to protected line without polarity constraint |
| Terminal 2 | Cathode (bidirectional) | Other side of symmetrical PN junction - completes bidirectional clamping path; no band marking |
Key Features
| Feature | Design Value |

| Low clamping ratio | VC/VBR ≈ 1.40 - ensures tight voltage control during transients, minimizing stress on downstream MOSFETs or MCUs |
| AEC-Q101 readiness | E3 suffix supports qualification path; HE3 variant is fully AEC-Q101 qualified - suitable for automotive sensor and body electronics |
| MSL Level 1 | Reflow-compatible up to 260 °C peak - enables standard SMT assembly without moisture sensitivity concerns |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus nodes and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector interface to shunt transients before they reach signal conditioning circuitry. Use Value: Clamps 10/1000 µs surges to ≤18.2 V, safeguarding 3.3 V/5 V microcontrollers and ADC front-ends rated for ≤20 V absolute maximum. |
Use Scenario: Shielding digital input modules in programmable logic controllers from field-wiring induced surges (e.g., relay coil switching, motor noise). IC Role / Device Role / Timing Role: Primary overvoltage suppressor on 24 V DC input channels, mounted adjacent to terminal block entry point. Use Value: Withstands ≥82.4 A peak current and recovers within nanoseconds - prevents latch-up or permanent damage to optocoupler input stages. |
| Telecom Line Interface | Consumer Power Adapter Output |
Use Scenario: Safeguarding Ethernet PHYs and PoE injectors against lightning-induced common-mode surges on twisted-pair lines. IC Role / Device Role / Timing Role: Paired bidirectionally across differential pairs (e.g., TX+/TX−) to clamp mode-common transients without distorting signal integrity. Use Value: Low 18.2 V clamping voltage preserves margin below 25 V PHY rail limits while maintaining <1 ns response for sub-100 ns transients. |
Use Scenario: Secondary-side transient suppression on 12 V/19 V outputs of AC-DC adapters used in laptops and monitors. IC Role / Device Role / Timing Role: Final-stage protector between DC-DC converter output and connector - absorbs residual switching spikes and hot-plug transients. Use Value: 1500 W rating handles repeated 100–500 V surges from capacitor discharge or cable coupling, extending adapter MTBF by >3× vs. lower-rated TVS devices. |
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 function, but lower 600 W PPPM in SMB package | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump | Select when board space is constrained and surge threat level is ≤600 W (e.g., internal PCB traces only) |
| 1.5KE13CA | Through-hole TO-204AA (DO-41) package; identical 13 V rating and 1500 W rating, but larger footprint and manual assembly required | Used where reworkability or high-reliability mechanical anchoring is prioritized over SMT automation | Choose for legacy designs, prototyping, or high-vibration environments where SMT adhesion risk exists |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CA-E3/57T uniquely balances 1500 W surge capability, SMC's automated placement compatibility, and bidirectional symmetry - making it optimal for volume automotive and industrial SMT production where both performance and process efficiency matter.

FAQ
What is the clamping voltage of the 1.5SMC13CA-E3/57T under maximum surge conditions?
The 1.5SMC13CA-E3/57T clamps to 18.2 V when subjected to its rated 82.4 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on 8.0 mm × 8.0 mm copper pads and represents the maximum voltage seen by downstream circuitry during worst-case transient events - a critical parameter for ensuring compatibility with 3.3 V or 5 V logic rails.
Is the 1.5SMC13CA-E3/57T suitable for automotive applications?
Yes - the 1.5SMC13CA-E3/57T is RoHS-compliant and supports AEC-Q101 qualification via the HE3 suffix (e.g., 1.5SMC13CAHE3_A). While the E3/57T variant itself is commercial-grade, its construction (glass-passivated junction, MSL Level 1, -65 °C to +150 °C operation) aligns with automotive environmental demands, and it is widely used in non-safety-critical sensor and body electronics where full qualification is not mandated.
How does the bidirectional design of the 1.5SMC13CA-E3/57T affect PCB layout?
The 1.5SMC13CA-E3/57T has no polarity marking and symmetric electrical behavior, so PCB layout requires no orientation alignment - either terminal may connect to the protected line or ground/reference plane. This simplifies routing, reduces assembly errors, and enables use in differential or AC-coupled paths where voltage polarity reverses, such as telecom line interfaces or motor feedback signals.
What is the thermal resistance of the 1.5SMC13CA-E3/57T, and how does it impact power dissipation?
The 1.5SMC13CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard SMC mounting conditions. At ambient temperatures above 25 °C, its 6.5 W steady-state power dissipation (PD) must be derated linearly - for example, at 75 °C ambient, usable PD drops to ~4.9 W. This matters most in sustained overvoltage fault conditions, not transient suppression where energy is absorbed capacitively.
Can the 1.5SMC13CA-E3/57T replace unidirectional TVS diodes like 1.5SMC13A-E3/57T in existing designs?
No - the 1.5SMC13CA-E3/57T is strictly bidirectional and lacks cathode band marking, whereas 1.5SMC13A-E3/57T is unidirectional with defined polarity. Substituting them requires verifying that the circuit does not rely on DC blocking in one direction (e.g., bias networks or rectification paths); if polarity-sensitive, replacement would cause functional failure or excessive leakage.
