Product details
Overview
1.5SMC180CA-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 1500 W peak pulse power rating (10/1000 µs), 180 V breakdown voltage (VBR min = 171 V, max = 189 V at IT = 1 mA), and clamps transients to ≤246 V at 6.1 A peak pulse current - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC180CA-E3/57T datasheet, 1.5SMC180CA-E3/57T pinout, 1.5SMC180CA-E3/57T application, or 1.5SMC180CA-E3/57T equivalent, this page delivers verified electrical specs, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal derating curves, and AEC-Q101-compliant alternatives for automotive-grade surge protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VWM (154 V), and VC (246 V) ratings in forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and lightning-induced transients on unprotected lines.
Rated for 150 °C maximum junction temperature and MSL Level 1 moisture sensitivity, the device sustains repetitive 10/1000 µs surges at 0.01% duty cycle when mounted on 8.0 mm × 8.0 mm copper pads. Thermal resistance is RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), supporting reliable operation under transient overload without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at IT = 1 mA - defines precise voltage threshold where clamping begins in either polarity |
| VWM | 154 V - maximum continuous reverse stand-off voltage before leakage exceeds 1 μA |
| VC @ IPPM | 246 V at 6.1 A - clamped voltage during full 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs waveform) - peak surge energy handling capacity for lightning/inductive switching events |
| IPPM | 6.1 A - peak pulse current corresponding to VC = 246 V, used for PCB trace sizing and layout margining |
| TJ max | +150 °C - enables use in under-hood automotive environments and high-ambient industrial enclosures |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1, compatible with lead-free reflow (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal A | One side of symmetrical bidirectional junction - no polarity marking; interchangeable with Cathode in layout |
| Cathode | Terminal B | Other side of symmetrical bidirectional junction - electrically identical to Anode; no band marking required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and leakage performance in both directions - eliminates polarity concerns in AC or floating signal lines |
| 1500 W peak pulse power | Withstands 10/1000 µs transients per IEC 61000-4-5 Level 4 without degradation - suitable for harsh industrial and automotive surge environments |
| Glass-passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<1 μA at VWM), and long-term reliability under thermal cycling |
| AEC-Q101 qualified option | E3 suffix indicates RoHS-compliant commercial grade; HE3 variant available for automotive qualification - same electrical specs, enhanced process control |
| Low thermal resistance | RθJL = 15 °C/W enables efficient heat transfer to PCB copper - supports sustained operation near TJ limit during repeated surges |
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 ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed at connector entry point to clamp ±100 V transients before they reach MCU or signal conditioner ICs. Use Value: Limits induced voltage to ≤246 V, preventing latch-up or gate oxide damage in 3.3 V/5 V interface ICs while maintaining signal integrity. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers against field-wiring faults and inductive kickback from solenoids/relays. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC input channels, operating alongside series resistors and filtering capacitors. Use Value: Absorbs up to 1500 W surge energy without failure, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Secondary-side protection on Ethernet PHY power rails and RS-485 transceiver VCC pins exposed to cable-borne transients. IC Role / Device Role / Timing Role: Low-capacitance (CJ < 100 pF typical) bidirectional clamp placed adjacent to IC pins to minimize signal distortion. Use Value: Clamps fast-rising transients (<1 ns response) while adding negligible capacitance to high-speed data lines - preserves signal rise/fall times. |
Use Scenario: Input-stage surge suppression on AC-DC adapter primary-side rectifier outputs and secondary-side 12 V/19 V rails. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing line-to-line and line-to-ground surges during lightning strikes or grid switching events. Use Value: Withstands 6.1 A peak current at 246 V clamp level, protecting downstream regulators and MOSFETs without requiring oversized heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Same VBR (171–189 V), lower PPPM = 600 W, SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients (IEC 61000-4-2 ESD only); not suitable for IEC 61000-4-5 Level 3/4 | Select when space-constrained layouts prioritize footprint over surge margin - verify thermal derating at 100 °C ambient. |
| 1.5KE180CA | Same VBR and PPPM, but axial DO-201AD package - higher RθJA (~100 °C/W), manual assembly only | Not suitable for automated SMT production; requires through-hole routing and wave soldering | Choose only for legacy repair, prototyping, or non-SMT applications where board real estate is unrestricted. |
Compared with SMBJ180CA and 1.5KE180CA, the 1.5SMC180CA-E3/57T delivers optimal balance of high-energy surge capability (1500 W), SMT manufacturability, and thermal performance - making it the preferred choice for new automotive and industrial designs requiring AEC-Q101 alignment and automated assembly.

FAQ
What is the breakdown voltage tolerance for 1.5SMC180CA-E3/57T?
The 1.5SMC180CA-E3/57T has a breakdown voltage range of 171 V to 189 V at test current IT = 1 mA, representing a ±5% tolerance around the nominal 180 V rating. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes from −65 °C to +150 °C.
Is 1.5SMC180CA-E3/57T suitable for automotive applications?
Yes - while the base 1.5SMC180CA-E3/57T is RoHS-compliant commercial grade, the same die and package are offered in AEC-Q101 qualified variants (e.g., 1.5SMC180CAHE3_A). The 1.5SMC180CA-E3/57T shares identical electrical characteristics and thermal performance, making it suitable for non-safety-critical automotive subsystems such as body control modules and infotainment power rails.
What is the maximum clamping voltage of 1.5SMC180CA-E3/57T under surge conditions?
The 1.5SMC180CA-E3/57T clamps to a maximum of 246 V when subjected to its rated 6.1 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage margining in circuit design.
Does 1.5SMC180CA-E3/57T require polarity-aware PCB layout?
No - the "CA" suffix denotes bidirectional construction, meaning the 1.5SMC180CA-E3/57T has symmetrical electrical characteristics in both directions and carries no cathode band marking. Either terminal may be connected to line or ground; PCB layout need not observe orientation, simplifying placement and reducing assembly errors.
How does the SMC package of 1.5SMC180CA-E3/57T compare thermally to SMA or SMB packages?
The SMC (DO-214AB) package used by 1.5SMC180CA-E3/57T provides lower thermal resistance than SMA (DO-214AC) or SMB (DO-214AA): RθJA = 75 °C/W (typ.) vs. ~100–120 °C/W for smaller outlines. This allows the 1.5SMC180CA-E3/57T to sustain higher average power dissipation and recover faster between surges - critical in high-duty-cycle industrial environments.
