Product details
Overview
1.5SMC10CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 10 V standoff voltage (VWM), and clamps to ≤14.5 V at 103 A peak pulse current. It protects signal lines and power rails in automotive sensor interfaces and industrial I/O modules against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the 1.5SMC10CA-E3/57T datasheet, 1.5SMC10CA-E3/57T pinout, 1.5SMC10CA-E3/57T application, or 1.5SMC10CA-E3/57T equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal derating curves, RoHS-compliant commercial-grade qualification, and real-world protection use cases - all aligned with Vishay Document 88303 Rev. 09-Mar-2026.
Technical Context
The 1.5SMC10CA-E3/57T operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics, enabling bidirectional transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR (9.5–10.5 V at 1 mA) and low incremental surge resistance, critical for fast response (<1 ns) to sub-microsecond transients.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power under JEDEC-standard 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance RθJA = 75 °C/W and maximum junction temperature of +150 °C. It meets MSL Level 1 per J-STD-020 and supports reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - Tight tolerance ensures predictable turn-on during overvoltage events; guarantees clamping starts within ±5% of nominal rating. |
| VC (Clamping Voltage) | ≤14.5 V at IPPM = 103 A - Limits downstream voltage stress during worst-case 1500 W surge; enables robust protection of 15 V-tolerant ICs. |
| PPPM (Peak Pulse Power) | 1500 W (10/1000 μs) - Sustains high-energy transients common in automotive load-dump and industrial motor switching environments. |
| ID (Reverse Leakage) | ≤10 μA at VWM - Minimizes standby power loss and avoids false triggering in low-current sensor bias networks. |
| TJ max | +150 °C - Supports operation in under-hood automotive and high-ambient industrial enclosures without thermal shutdown. |
| Package | SMC (DO-214AB) - Industry-standard 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; optimized for automated placement and thermal pad layout. |
Pinout & Package
SMC (DO-214AB) package: 2-terminal, symmetrical bidirectional device with no polarity marking; both terminals function identically as anode/cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Bidirectional Surge Terminal | Connects to protected line (e.g., CAN_H or RS-485 A); conducts transient current in either direction when voltage exceeds VBR. |
| Terminal 2 | Bidirectional Surge Terminal | Connects to reference plane (GND or complementary line); completes low-inductance path for surge current return during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W Peak Pulse Power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV) surges on 12 V buses without cascaded TVS stages. |
| Glass-Passivated Junction | Ensures long-term stability of VBR and leakage across temperature (-65 °C to +150 °C) and lifetime cycling. |
| MSL Level 1 Rating | Supports standard lead-free reflow profiles (peak 260 °C) without preconditioning or moisture sensitivity handling. |
| RoHS-Compliant (E3) | Meets EU Directive 2011/65/EU and JESD201 Class 2 whisker resistance; suitable for consumer and industrial production. |

Applications
| Automotive Sensor Interface | Industrial RS-485 Bus |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load-dump and battery reverse-polarity transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point, shunting surge energy to chassis ground before reaching signal conditioning circuitry. Use Value: Maintains signal integrity during 12 V system transients up to ±100 V/10 ms, preventing false readings or microcontroller resets without adding series impedance. |
Use Scenario: Safeguarding half-duplex RS-485 transceivers (e.g., MAX13487, SN65HVD72) in factory automation PLCs exposed to motor drive noise and ground bounce. IC Role / Device Role / Timing Role: Common-mode transient suppressor across differential pair (A–B) and to ground, absorbing common-mode surges while preserving data eye integrity. Use Value: Limits differential voltage excursion to <14.5 V during 1 kV/500 A surge events, ensuring reliable communication at 250 kbps over 1200 m cable runs. |
| Consumer USB Port Protection | Telecom DSL Line Interface |
Use Scenario: Secondary-level ESD and surge protection for USB 2.0 D+/D− lines in set-top boxes and smart displays subjected to human-body-model (HBM) discharges. IC Role / Device Role / Timing Role: Fast-response clamping device placed after primary polymer PTC, providing low-capacitance (<100 pF) overvoltage limiting without signal distortion. Use Value: Withstands ±15 kV contact discharge per IEC 61000-4-2 while adding <0.5 pF parasitic capacitance, preserving signal rise time and eye diagram compliance. |
Use Scenario: Front-end protection for ADSL/VDSL line drivers and SLIC circuits in residential gateways exposed to lightning-induced longitudinal surges on twisted-pair telephone lines. IC Role / Device Role / Timing Role: Symmetrical bidirectional suppressor bridging tip/ring to ground, diverting >100 A surge currents away from transformer-coupled analog front-end. Use Value: Clamps longitudinal mode surges to <14.5 V peak, preventing saturation of line transformers and maintaining -40 dB crosstalk performance up to 30 MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Lower PPPM (600 W), same VWM (10 V), SMB package (smaller footprint, higher RθJA = 110 °C/W) | Suitable for space-constrained consumer PCBs but derates faster above 70 °C ambient; not recommended for automotive under-hood use. | Select SMBJ10CA only if board area is critical and peak surge energy remains ≤600 W; verify thermal margin with actual layout. |
| 1.5KE10CA | Same 1500 W rating and VWM, but axial DO-15 through-hole package; higher mounting inductance limits high-frequency ESD response. | Preferred for legacy through-hole designs or prototyping where reworkability outweighs board density; unsuitable for high-speed data lines due to lead inductance. | Choose 1.5KE10CA for manual assembly or repair scenarios; avoid in new SMT designs targeting >100 MHz transient immunity. |
Compared with SMBJ10CA and 1.5KE10CA, the 1.5SMC10CA-E3/57T uniquely balances high-power surge handling (1500 W), industry-standard SMC footprint, and low thermal resistance (75 °C/W) - making it optimal for production-grade automotive and industrial SMT assemblies requiring repeatable, high-reliability clamping performance.

FAQ
What is the clamping voltage of the 1.5SMC10CA-E3/57T at its rated peak pulse current?
The 1.5SMC10CA-E3/57T clamps to a maximum of 14.5 V at its rated peak pulse current (IPPM) of 103 A, measured under the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range (-65 °C to +150 °C) and ensures downstream ICs rated for 15 V absolute maximum survive worst-case surge events without damage.
Is the 1.5SMC10CA-E3/57T suitable for automotive applications?
Yes - the 1.5SMC10CA-E3/57T is RoHS-compliant and qualified to commercial-grade specifications per Vishay's 1.5SMC Series documentation. While the base E3 suffix denotes commercial grade, AEC-Q101-qualified versions exist under HE3 suffix (e.g., 1.5SMC10CAHE3_A). For non-safety-critical automotive subsystems like cabin sensors or infotainment I/O, the 1.5SMC10CA-E3/57T provides proven surge resilience and thermal stability up to +150 °C junction temperature.
How does the bidirectional design of the 1.5SMC10CA-E3/57T affect its circuit placement?
The 1.5SMC10CA-E3/57T has no polarity marking and functions identically in both directions, allowing direct placement across differential lines (e.g., RS-485 A/B), between signal and ground, or across power rails without orientation concerns. This eliminates assembly errors and simplifies layout - especially in balanced interface protection where symmetric clamping is required to maintain common-mode rejection.
What is the thermal resistance and how does it impact PCB layout for the 1.5SMC10CA-E3/57T?
The 1.5SMC10CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal, as specified in Vishay Document 88303. To maintain safe junction temperatures under repetitive surges, PCB layout must replicate this pad area - undersized pads increase thermal resistance, causing premature thermal derating and reduced surge endurance.
Does the 1.5SMC10CA-E3/57T meet any safety or flammability standards?
Yes - the 1.5SMC10CA-E3/57T uses molding compound rated UL 94 V-0 for flammability, and Vishay lists Underwriters Laboratories (UL) recognition under file E136766 for both unidirectional and bidirectional devices per UL 497B. This certification validates its suitability for use in end equipment requiring recognized surge protection components, including industrial control panels and telecom infrastructure.
