Product details
Overview
1.5SMC16CA-M3/57T 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), 16 V standoff voltage (VWM), and clamping voltage of 22.5 V at 66.7 A peak pulse current - deployed for ESD and lightning surge protection on signal lines and power rails in automotive sensor interfaces and industrial I/O modules.
For engineers reviewing the 1.5SMC16CA-M3/57T datasheet, 1.5SMC16CA-M3/57T pinout, 1.5SMC16CA-M3/57T application, or 1.5SMC16CA-M3/57T equivalent, key selection criteria include bidirectional clamping symmetry, M3 halogen-free RoHS compliance, 150 °C max junction temperature, and compatibility with automated SMT placement on 8 mm × 8 mm copper pads per terminal.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and low incremental surge resistance. Its bidirectional architecture eliminates polarity sensitivity during board-level surge events.
Rated for 1500 W peak pulse power under standardized 10/1000 µs waveform and derated above 25 °C ambient, it maintains stable clamping performance across -65 °C to +150 °C operating junction temperature range, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - guaranteed symmetric breakdown in both directions; ensures predictable turn-on during transients |
| VC (Clamping) | 22.5 V at 66.7 A - peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress |
| PPPM | 1500 W - peak transient energy absorption capability; supports high-energy lightning-induced surges per IEC 61000-4-5 |
| IPPM | 66.7 A - maximum non-repetitive surge current the device can safely divert without degradation |
| TJ max | +150 °C - maximum allowable junction temperature; enables operation in under-hood automotive and industrial environments |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 8.0 mm × 8.0 mm thermal pad footprint for reliable heat dissipation |
Pinout & Package
SMC (DO-214AB) package: molded plastic body with matte tin-plated leads, compliant with J-STD-002 and JESD 22-B102 solderability standards; no polarity marking required for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Identical electrical behavior in either direction; terminals interchangeable in PCB layout |
Key Features
| Feature | Design Value |

| Halogen-free, RoHS-compliant (M3) | Supports environmental compliance for global OEM programs and end-of-life recycling mandates |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without moisture sensitivity handling |
| Glass-passivated junction | Ensures long-term reliability and stable leakage characteristics (<1 μA at VWM) over temperature and life |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp fast-rising transients before reaching sensitive IC inputs. Use Value: Maintains signal integrity under ±22.5 V clamping while surviving repetitive 10/1000 µs surges up to 1500 W without parameter shift. |
Use Scenario: Shielding 4–20 mA current-loop inputs and 0–10 V analog channels in programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input terminals, coordinated with series current-limiting resistors and filtering capacitors. Use Value: Prevents latch-up or damage to precision op-amps and ADCs by limiting transient voltage to ≤22.5 V at full 66.7 A surge current. |
| Telecom Line Card Protection | Consumer USB Port ESD |
Use Scenario: Safeguarding Ethernet PHYs and PoE injectors on telecom line cards exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Common-mode TVS pair (or standalone bidirectional unit) across differential pairs or power/return paths. Use Value: Delivers symmetrical 15.2–16.8 V breakdown and 22.5 V clamping to preserve signal timing margins and avoid data corruption. |
Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D− lines and VBUS in portable devices, supplementing internal IC protection. IC Role / Device Role / Timing Role: Fast-response shunt device that activates within <1 ns to divert >8 kV HBM ESD events away from USB controller pins. Use Value: Achieves <1 μA leakage at 13.6 V VWM, minimizing standby current impact while ensuring robust 1500 W surge handling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Lower peak power rating (600 W), same VWM/VC, SMB (DO-214AA) package with smaller thermal pad area | Limited to lower-energy transients (IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is limited to ESD and switching noise |
| 1.5KE16CA | Through-hole DO-15 package, identical electrical specs but higher RθJA (100 °C/W), no M3 halogen-free option | Not compatible with automated SMT assembly; requires wave solder or hand-soldering | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ16CA and 1.5KE16CA, the 1.5SMC16CA-M3/57T delivers superior surge robustness in an SMT-optimized, halogen-free package - making it the preferred choice for production-grade automotive and industrial designs requiring 1500 W clamping and AEC-Q101-aligned reliability.

FAQ
What is the clamping voltage of the 1.5SMC16CA-M3/57T under a 10/1000 µs surge?
The 1.5SMC16CA-M3/57T clamps to a maximum of 22.5 V at 66.7 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured per Figure 1 in Vishay Document 88303 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC16CA-M3/57T suitable for automotive applications?
Yes, the 1.5SMC16CA-M3/57T meets AEC-Q101 qualification when ordered with HE3 or HM3 suffixes; although the M3/57T variant is commercial-grade, its 150 °C junction rating, glass-passivated junction, and MSL Level 1 reflow compatibility make it widely adopted in non-safety-critical automotive sensor and infotainment subsystems. Always verify qualification status via the specific ordering code.
Does the 1.5SMC16CA-M3/57T require polarity-aware PCB layout?
No - the 1.5SMC16CA-M3/57T is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. Its SMC (DO-214AB) package has no cathode band or polarity marking, allowing unrestricted orientation during automated placement and eliminating risk of reverse installation errors in production.
What is the maximum steady-state power dissipation for the 1.5SMC16CA-M3/57T?
The 1.5SMC16CA-M3/57T has a maximum steady-state power dissipation (PD) of 6.5 W when mounted on an infinite heatsink at TA = 50 °C. In typical PCB layouts with 8.0 mm × 8.0 mm copper pads per terminal, derating applies above 25 °C ambient per Figure 2 in the datasheet - actual usable DC power depends on thermal design and airflow.
How does the M3 suffix affect the 1.5SMC16CA-M3/57T?
The M3 suffix on the 1.5SMC16CA-M3/57T indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. It does not alter electrical parameters but ensures compliance with environmental regulations including EU RoHS Directive 2011/65/EU and JEDEC JS709E material restrictions.
