Product details
Overview
SM15T200CAHM3/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 200 V standoff voltage (VWM), and clamping voltage of 328 V at 4.6 A peak pulse current. It protects signal lines and power rails in automotive sensor units and industrial I/O interfaces against lightning-induced and switching transients.
For engineers reviewing the SM15T200CAHM3/H datasheet, SM15T200CAHM3/H pinout, SM15T200CAHM3/H application, or SM15T200CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, and verified 1500 W surge handling per JEDEC-standard waveform.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. Its 200 V standoff voltage ensures compatibility with 171 V DC bus systems, while clamping at 328 V limits downstream stress during 4.6 A transients.
Thermal resistance is 75 °C/W junction-to-ambient (typical) on standard 8.0 mm × 8.0 mm copper pads, and it sustains 150 °C maximum junction temperature. The device features glass-passivated junctions and meets MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 200 V - Maximum continuous reverse operating voltage before conduction begins; sets system-level overvoltage threshold. |
| VBR min / max | 209 V / 231 V at 1 mA - Confirmed breakdown range ensures reliable turn-on margin above VWM. |
| VC @ IPPM | 328 V at 4.6 A (10/1000 μs) - Clamping voltage defines worst-case voltage seen by protected ICs during surge events. |
| PPPM | 1500 W - Peak pulse power rating validates protection against lightning surges (IEC 61000-4-5 Level 4) and motor-switching transients. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| RθJA | 75 °C/W - Thermal resistance measured on 8.0 mm × 8.0 mm copper pads; informs heatsinking requirements for repetitive surge duty. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Dimensions: 7.11 mm × 6.22 mm × 2.62 mm (L × W × H); matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common node for bidirectional clamping path | No polarity marking; symmetric terminals enable AC-coupled or floating-line protection without orientation constraints. |
| Cathode | Current exit terminal in forward bias; common node for bidirectional clamping path | Identical electrical role to Anode; bidirectional symmetry eliminates need for cathode band identification. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Validates robustness against IEC 61000-4-5 combination wave surges up to 4 kV open-circuit / 2 kA short-circuit. |
| AEC-Q101 qualified (HM3 suffix) | Confirms reliability for automotive applications including engine control modules, ADAS sensor interfaces, and body electronics. |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declaration requirements for green manufacturing. |
| Low inductance design | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), critical for protecting high-speed digital interfaces. |
| MSL Level 1 (260 °C peak) | Supports single-reflow assembly without moisture sensitivity concerns, reducing manufacturing risk and cost. |
Applications
| Automotive Sensor Protection | Industrial I/O Port Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A | Unidirectional; 200 V VWM; 324 V VC @ 4.7 A; 400 W PPPM; SMA package (smaller thermal mass) | Limited to DC-biased lines; insufficient for AC-coupled or floating differential buses like CAN or RS-485 | Select only for cost-sensitive, non-automotive designs with unidirectional bias and lower surge exposure. |
| SMCJ200CA | Bidirectional; 200 V VWM; 324 V VC @ 4.6 A; 1500 W PPPM; same SMC package; AEC-Q101 not specified in base version | Same clamping performance but lacks HM3 suffix - no documented AEC-Q101 qualification or halogen-free assurance | Acceptable for industrial use where automotive qualification is not required; verify M3 vs HM3 material compliance per batch. |

FAQ
What is the clamping voltage of SM15T200CAHM3/H at its rated peak pulse current?
The SM15T200CAHM3/H clamps to 328 V when subjected to a 4.6 A peak pulse current with a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88380 and defines the maximum voltage imposed on protected circuitry during standardized surge testing.
Is SM15T200CAHM3/H qualified for automotive applications?
Yes, SM15T200CAHM3/H carries the HM3 suffix, indicating halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. This certification covers stress tests including temperature cycling, humidity bias, and mechanical shock - confirming suitability for under-hood and chassis-mounted automotive electronics.
What does the "CA" suffix indicate in SM15T200CAHM3/H?
The "CA" suffix in SM15T200CAHM3/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities. Unlike unidirectional variants (e.g., SM15T200AHM3/H), it requires no polarity alignment during placement and supports AC-coupled or floating signal lines.
What is the thermal resistance of SM15T200CAHM3/H under standard mounting conditions?
SM15T200CAHM3/H 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. This value assumes JEDEC-standard board layout and is used to calculate junction temperature rise under sustained power dissipation.
Does SM15T200CAHM3/H meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, SM15T200CAHM3/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This allows unlimited floor life and single-reflow processing without baking, simplifying SMT line integration for high-volume manufacturing.
