Product details
Overview
1.5SMC100CA-M3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 100 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in automotive sensor interfaces and industrial I/O modules against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC100CA-M3/9AT datasheet, 1.5SMC100CA-M3/9AT pinout, 1.5SMC100CA-M3/9AT application, or 1.5SMC100CA-M3/9AT equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification readiness via HM3 variant.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal bias it exhibits <1 μA reverse leakage at 85.5 V (VWM), and triggers avalanche conduction when transient voltage exceeds its 95–105 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
The 1.5SMC100CA-M3/9AT delivers symmetrical clamping in both directions - critical for AC-coupled data lines and differential buses - with identical VC = 137 V and IPPM = 10.9 A regardless of polarity. Thermal design relies on RθJA = 75 °C/W and RθJL = 15 °C/W, requiring minimum 8.0 mm × 8.0 mm copper pads per terminal for full 1500 W rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - precise avalanche onset range ensuring predictable trigger threshold across temperature |
| VC (Clamping Voltage) | 137 V at IPPM = 10.9 A - peak voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM (Peak Pulse Power) | 1500 W - energy-handling capacity for standardized lightning/surge immunity testing (IEC 61000-4-5) |
| Package | SMC (DO-214AB) - surface-mount outline with 7.75 mm × 6.22 mm footprint, compatible with automated pick-and-place |
| RoHS & Halogen-Free | M3 suffix - meets JESD201 Class 2 whisker resistance and IPC-4101D/126B material requirements |
| Operating Temperature | –65 °C to +150 °C - supports under-hood automotive and high-ambient industrial environments |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; polarity-unmarked for bidirectional operation; no cathode/anode designation required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Terminal 1 | AC input node | Either terminal accepts transient voltage in either polarity; symmetric bidirectional conduction path |
| Cathode / Terminal 2 | AC input node | Electrically identical to Terminal 1; no functional distinction - device has no polarity marking |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM in both directions - eliminates need for polarity-aware layout in AC or differential signal protection |
| 1500 W peak pulse rating | Validated with 10/1000 μs waveform at 0.01% duty cycle - meets IEC 61000-4-5 Level 4 surge immunity requirements |
| Low clamping ratio (VC/VBR) | 137 V / 100 V ≈ 1.37 - tight voltage control minimizes stress on downstream ICs during transient events |
| MSL Level 1 rating | Reflow-compatible up to 260 °C peak - enables single-pass lead-free assembly without baking or special handling |
| AEC-Q101 readiness | M3 suffix base qualifies for HM3 automotive variants - supports qualification path for automotive body electronics and ADAS sensors |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is ≤ Level 2 |
| 1.5KE100CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly | Requires manual or wave soldering; not suitable for high-density automated production | Choose only for legacy through-hole designs or prototyping where rework tolerance is prioritized |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CA-M3/9AT uniquely balances 1500 W surge capability, SMC surface-mount compatibility, and bidirectional symmetry - making it optimal for automotive and industrial SMT production where robustness and assembly efficiency are jointly critical.

FAQ
What does the "CA" suffix mean in 1.5SMC100CA-M3/9AT?
The "CA" suffix in 1.5SMC100CA-M3/9AT denotes a bidirectional configuration: the device provides symmetrical transient voltage suppression in both polarities, with identical breakdown (95–105 V), clamping (137 V), and peak pulse current (10.9 A) characteristics regardless of voltage polarity applied across its terminals.
Is 1.5SMC100CA-M3/9AT qualified to AEC-Q101?
The 1.5SMC100CA-M3/9AT itself is commercial-grade (M3 suffix); however, Vishay offers the HM3 variant (e.g., 1.5SMC100CAHM3_A/I) which is fully AEC-Q101 qualified. The M3 base construction - including glass-passivated junction, MSL Level 1 rating, and 150 °C TJ max - forms the foundation for that qualification path.
What is the maximum clamping voltage for 1.5SMC100CA-M3/9AT under surge conditions?
The maximum clamping voltage (VC) for 1.5SMC100CA-M3/9AT is 137 V, measured at the peak pulse current (IPPM) of 10.9 A using the standard 10/1000 μs double-exponential waveform - this value is guaranteed across the full operating temperature range (–65 °C to +150 °C).
Can 1.5SMC100CA-M3/9AT be used in place of a unidirectional TVS like 1.5SMC100A-M3/9AT?
No - 1.5SMC100CA-M3/9AT is strictly bidirectional and lacks polarity marking; substituting it for a unidirectional part (e.g., 1.5SMC100A-M3/9AT) would compromise forward-bias operation in DC-coupled circuits. Use only where bidirectional clamping is explicitly required, such as AC signal lines or differential buses.
What PCB pad layout is required to achieve the full 1500 W rating for 1.5SMC100CA-M3/9AT?
To achieve the full 1500 W peak pulse power rating, 1.5SMC100CA-M3/9AT must be mounted on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - as specified in Vishay's datasheet Figure 2 and thermal characterization. Smaller pads derate power handling significantly due to increased thermal resistance.
