Product details
Overview
1.5SMC200CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 µs). It clamps transients to ≤274 V at 5.5 A peak pulse current and operates across –65 °C to +150 °C junction temperature - deployed for ESD and lightning surge protection on automotive sensor signal lines.
For engineers reviewing the 1.5SMC200CAHM3_A/I datasheet, 1.5SMC200CAHM3_A/I pinout, 1.5SMC200CAHM3_A/I application, or 1.5SMC200CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and thermal resistance (RθJA = 75 °C/W) under standard SMC pad layout.
Technical Context
This device functions as a voltage-clamped shunt protector: during overvoltage events exceeding its VBR (220–242 V), it transitions from high-impedance to low-impedance state within <1 ps, diverting surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping behavior for positive and negative transients.
Designed for repetitive surge handling with 0.01% duty cycle, the 1.5SMC200CAHM3_A/I sustains 1500 W peak pulse power only when mounted on 8.0 mm × 8.0 mm copper pads per terminal and derated above 25 °C ambient per Fig. 2. Junction-to-lead thermal resistance is 15 °C/W, enabling localized heat dissipation without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 220–242 V at 1 mA - Voltage at which device initiates avalanche conduction; ensures predictable turn-on during transients. |
| VC (Clamping) | ≤274 V at IPPM = 5.5 A - Maximum voltage seen by protected circuit during full-rated 10/1000 µs surge; limits stress on downstream ICs. |
| PPPM | 1500 W - Peak transient power absorption capacity; enables robust protection against lightning-induced surges (IEC 61000-4-5 Level 4). |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient; requires defined 8.0 mm × 8.0 mm copper pad layout to meet derating curves. |
| TJ Range | –65 °C to +150 °C - Full operational junction temperature range; supports under-hood automotive environments. |
| Compliance | AEC-Q101 qualified, halogen-free, RoHS-compliant - Meets automotive reliability and environmental standards for production deployment. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 7.75 mm × 6.22 mm × 2.62 mm (L × W × H); matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Acts as cathode during positive transients and anode during negative transients; symmetrical conduction enables dual-polarity protection. |
| Cathode | Transient return path (bidirectional) | Electrically identical to Anode in bidirectional construction; no band marking distinguishes terminals. |
Key Features
| Feature | Design Value |
|---|---|

| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declaration requirements for green manufacturing. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns rise time), improving protection fidelity. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without moisture sensitivity concerns or baking requirements. |
Applications
| Automotive Sensor Signal Protection | Industrial CAN Bus Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Lower peak power (600 W), same VWM/VBR, SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load-dump scenarios. | Select when board space is constrained and surge threat level is moderate (e.g., consumer USB ports). |
| 1.5KE200CA | Through-hole TO-204AA (DO-41), identical electrical specs but incompatible mounting and thermal profile | Requires PCB redesign; lacks AEC-Q101 qualification and MSL Level 1 reflow compatibility. | Choose only for legacy through-hole designs where SMT migration is not feasible. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CAHM3_A/I delivers higher surge robustness in an automotive-qualified SMT package, enabling direct integration into modern ECU layouts without compromising thermal performance or compliance.

FAQ
What is the clamping voltage of the 1.5SMC200CAHM3_A/I at its rated peak pulse current?
The 1.5SMC200CAHM3_A/I has a maximum clamping voltage (VC) of 274 V at its rated peak pulse current (IPPM) of 5.5 A under a 10/1000 µs waveform. This value is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal and represents the upper voltage limit imposed on protected circuitry during full-rated surge events. The 1.5SMC200CAHM3_A/I maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC200CAHM3_A/I suitable for automotive applications?
Yes, the 1.5SMC200CAHM3_A/I is AEC-Q101 qualified (indicated by the HM3 suffix) and specifically designed for automotive use cases including engine control units, ADAS sensor interfaces, and body electronics. It meets stringent reliability requirements for temperature cycling, humidity resistance, and mechanical shock, and is halogen-free and RoHS-compliant to satisfy Tier 1 supplier mandates. The 1.5SMC200CAHM3_A/I operates from –65 °C to +150 °C, supporting under-hood environments.
How does the bidirectional configuration of the 1.5SMC200CAHM3_A/I affect its circuit implementation?
The 1.5SMC200CAHM3_A/I has no polarity marking and conducts identically in both directions, making it ideal for protecting AC-coupled or differential signal lines such as CAN bus, RS-485, or audio inputs. Unlike unidirectional TVS diodes, it requires no orientation during placement and clamps both positive and negative transients to the same VC level. This simplifies layout and eliminates risk of incorrect installation - critical in high-volume automotive assembly where the 1.5SMC200CAHM3_A/I is commonly used.
What is the thermal resistance of the 1.5SMC200CAHM3_A/I, and how does it impact PCB layout?
The 1.5SMC200CAHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Deviating from this pad size increases thermal resistance, accelerating junction temperature rise during repetitive surges and potentially triggering thermal runaway. To maintain reliability, the 1.5SMC200CAHM3_A/I must be placed with full copper fill under both terminals and avoid nearby heat sources or narrow traces.
Does the 1.5SMC200CAHM3_A/I have any special handling or assembly requirements?
The 1.5SMC200CAHM3_A/I is rated MSL Level 1 per J-STD-020, meaning it can withstand peak reflow temperatures up to 260 °C without baking or dry-pack requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and it passes JESD 201 Class 2 whisker testing. No special storage or handling is needed beyond standard ESD-safe practices - a key advantage for automated placement in high-yield automotive manufacturing where the 1.5SMC200CAHM3_A/I is widely deployed.
