Product details
Overview
SM15T10CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 10 V stand-off voltage (VWM), and clamps to ≤14.5 V at 103 A peak pulse current. It protects signal lines and power rails in automotive sensor units and industrial I/O interfaces against lightning-induced and switching transients.
For engineers reviewing the SM15T10CA-E3/57T datasheet, SM15T10CA-E3/57T pinout, SM15T10CA-E3/57T application, or SM15T10CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 10 V VWM compatibility with 3.3 V–12 V logic interfaces, low clamping ratio (1.45×VWM), and AEC-Q101 qualification readiness via HE3 suffix variants.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 11.4–12.6 V at 1 mA test current and maximum clamping voltage (VC) of 14.5 V at 103 A IPPM (10/1000 μs). Its low dynamic impedance ensures effective suppression of fast-rising transients up to 8/20 μs waveform.
Designed for surface-mount placement on PCBs with minimum 8.0 mm × 8.0 mm copper pads per terminal, it achieves thermal resistance RθJA = 75 °C/W and supports continuous operation from −65 °C to +150 °C junction temperature. The glass-passivated junction and matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Blocks normal operating voltages up to 10 V DC while remaining non-conductive. |
| VBR (Breakdown Voltage) | 11.4–12.6 V at 1 mA - Ensures reliable avalanche conduction onset during overvoltage events. |
| VC (Clamping Voltage) | ≤14.5 V at 103 A (10/1000 μs) - Limits downstream voltage stress to safe levels for 3.3 V/5 V/12 V ICs. |
| PPPM (Peak Pulse Power) | 1500 W - Handles high-energy transients from lightning surges or inductive load switching. |
| IPP (Peak Pulse Current) | 103 A - Sustains single-event surge currents without degradation under defined waveform conditions. |
| Package | SMC (DO-214AB) - Industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height. |
| RoHS Compliance | E3 suffix - Lead-free, RoHS-compliant, commercial-grade construction per JEDEC standards. |
Pinout & Package
SM15T10CA-E3/57T uses the SMC (DO-214AB) package: molded plastic case with two coplanar terminals, no polarity marking for bidirectional configuration, and matte tin-plated leads compatible with lead-free reflow (peak 260 °C, MSL Level 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient path | No polarity designation; either terminal serves as input/output for clamping in both directions. |
| Case (body) | Thermal and mechanical interface | Non-electrical; provides mechanical anchoring and contributes to thermal dissipation via PCB copper pads. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 (4 kV line-to-line) surges without derating. |
| Low clamping ratio (VC/VWM ≈ 1.45) | Minimizes voltage overshoot during clamping, preserving margin for 12 V-rated components. |
| Glass-passivated junction | Ensures stable VBR and leakage performance across temperature and long-term operation. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking prior to assembly. |
| Low inductance design | Reduces voltage overshoot during fast transients (<1 ns rise time), critical for high-speed data lines. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Use Value: Junction capacitance <100 pF at 0 V bias preserves signal integrity up to 480 Mbps while clamping ±15 kV ESD strikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Lower PPPM (400 W), same VWM (10 V), SMC-compatible but smaller SMA package (DO-214AC) | Limited to lower-energy threats (IEC 61000-4-2 only); unsuitable for lightning-survivable designs | Select SMAJ10CA only when board space is constrained and surge threat level is ≤1 kV line-to-ground. |
| SMCJ10CA | Higher PPPM (1500 W), identical VWM (10 V), same SMC package but higher IPPM (123 A) and lower VC (13.6 V) | Better clamping performance and margin for 12 V systems; slightly higher cost and larger thermal pad requirement | Choose SMCJ10CA when tighter clamping (VC ≤13.6 V) and extended surge lifetime are required for mission-critical industrial use. |
Compared with SMAJ10CA and SMCJ10CA, SM15T10CA-E3/57T delivers balanced performance: superior energy handling versus SMAJ10CA without SMCJ10CA's tighter thermal layout constraints, making it optimal for cost-sensitive automotive and industrial designs requiring AEC-Q101 readiness and proven field reliability.

FAQ
What is the clamping voltage of SM15T10CA-E3/57T at its rated peak pulse current?
The SM15T10CA-E3/57T has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform at 103 A peak pulse current (IPPM). This value is measured under standardized test conditions with 8.0 mm × 8.0 mm copper pads per terminal and confirms its ability to protect 12 V-rated downstream components without overstress.
Is SM15T10CA-E3/57T suitable for automotive applications?
SM15T10CA-E3/57T itself is RoHS-compliant commercial grade (E3 suffix), but the SM15T10CAHE3 variant is AEC-Q101 qualified. For automotive use, engineers must specify the HE3 suffix version; the E3/57T variant is appropriate for non-safety-critical subsystems or prototyping where qualification is pending.
Does SM15T10CA-E3/57T have polarity markings on the package?
No - SM15T10CA-E3/57T is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows installation in either orientation on the PCB, simplifying automated placement and eliminating orientation-related assembly errors.
What is the thermal resistance of SM15T10CA-E3/57T from junction to ambient?
The typical thermal resistance (RθJA) of SM15T10CA-E3/57T is 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value assumes still air conditions and defines the steady-state temperature rise above ambient at 6.5 W continuous power dissipation.
Can SM15T10CA-E3/57T be used in place of a unidirectional TVS like SM15T10A-E3/57T?
No - SM15T10CA-E3/57T is bidirectional and lacks polarity, whereas SM15T10A-E3/57T is unidirectional with a marked cathode. Substitution requires circuit review: bidirectional use is mandatory for AC-coupled or floating lines; unidirectional is required for DC-biased rails where reverse blocking is needed.
