Product details
Overview
1.5SMC200CH from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It delivers 1500W peak pulse power, 200V breakdown voltage (VBR = 180–220V), clamps to ≤287V at 5.4A peak impulse current, and operates across –55°C to +150°C junction temperature - deployed in DC power input stages of vehicle ECUs and industrial PLCs.
For engineers reviewing the 1.5SMC200CH datasheet, 1.5SMC200CH pinout, 1.5SMC200CH application, or 1.5SMC200CH equivalent, key selection criteria include bidirectional clamping capability, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, DO-214AB package thermal performance (RθJA = 50°C/W), and <1μA leakage at 162V working stand-off voltage.
Technical Context
The 1.5SMC200CH implements a glass-passivated silicon junction optimized for fast transient response (<1.0ps), enabling effective suppression of ESD, load dump, and lightning-induced surges. Its bidirectional configuration supports symmetric clamping in AC-coupled or floating bus applications without polarity constraints.
Thermally, it features RθJC = 15°C/W and RθJA = 50°C/W, allowing sustained operation up to 150°C junction temperature with appropriate PCB copper area. It meets AEC-Q101 stress testing and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180 V / 220 V - Ensures reliable triggering above system nominal voltage while avoiding false clamping during transients. |
| VWM | 162 V - Maximum continuous reverse operating voltage; defines safe DC bias margin before leakage rises. |
| VC @ IPPM | ≤287 V at 5.4 A - Clamped voltage under 10/1000µs surge; determines protected circuit's maximum overvoltage exposure. |
| PPK | 1500 W - Peak pulse power handling per single 10/1000µs waveform; defines surge energy absorption capacity. |
| IR @ VWM | ≤1 µA - Low leakage preserves efficiency in high-impedance sensing or battery-backed circuits. |
| TJ Range | –55°C to +150°C - Supports under-hood automotive and industrial ambient conditions without derating. |
| Package | DO-214AB (SMC) - Standardized SMT footprint with 0.210g mass and UL 94V-0 molding compound. |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode band marking for unidirectional variants; the 1.5SMC200CH is bidirectional and has no polarity marking - both terminals are functionally identical for transient clamping in either direction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | Both terminals conduct equally during positive or negative transients; no PCB orientation dependency. |
| Case | Thermal interface | Exposed metal slug provides primary heat conduction path to PCB copper; requires thermal pad per JEDEC MO-214. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics reliability including temperature cycling, HTRB, and ESD robustness. |
| ISO 7637-2 compliant | Withstands Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupled noise). |
| Glass passivated junction | Enhances long-term stability and moisture resistance vs. epoxy-passivated alternatives; critical for under-hood longevity. |
| Fast response time | <1.0 ps - Limits voltage overshoot before clamping engages, protecting downstream MOSFETs and microcontrollers. |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained designs. |
Applications
| Automotive Power Input Protection | Industrial DC Bus Surge Suppression |
|---|---|
Use Scenario: 12V/24V battery-fed ECU inputs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed directly at connector entry point before DC-DC converter input. Use Value: Limits transient voltage to ≤287V, preventing damage to upstream rectifiers and downstream regulators during 100V/100ms load dump events. | Use Scenario: 48V DC distribution rail in factory automation controllers subject to inductive switching noise and lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power bus, coordinated with upstream fuses and downstream TVS arrays. Use Value: Absorbs 1500W surge energy without degradation, maintaining bus integrity during 10/1000µs transients up to 5.4A. |
| Telecom Line Interface Protection | Renewable Energy Inverter DC Link |
Use Scenario: RS-485 or CAN bus power lines in outdoor telecom cabinets subjected to ESD and induced lightning surges. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing low-clamp backup for fast-rising transients. Use Value: Sub-1ps response ensures clamping occurs before GDT ionization completes, reducing overall let-through voltage. | Use Scenario: DC link between PV array and inverter in solar microinverters, where voltage can reach 200V under open-circuit conditions. IC Role / Device Role / Timing Role: Overvoltage limiter safeguarding IGBT gate drivers and DC-link capacitors during grid fault recovery. Use Value: 200V VBR aligns precisely with 200V max system voltage, enabling tight design margin without over-specification. |
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 | 600W rating (vs. 1500W); DO-214AA package; lower thermal mass and RθJA = 65°C/W. | Not suitable for ISO 7637-2 Pulse 5a load dump; limited to lower-energy ESD and signal-line transients. | Select only when peak surge energy is ≤600W and board space restricts DO-214AB use. |
| 1.5KE200CA | Through-hole TO-204AA (DO-41); same 1500W rating but slower response (~1ps vs. sub-1ps) and higher leakage (>5µA @ VWM). | Requires manual assembly; unsuitable for automated SMT lines or high-reliability automotive reflow profiles. | Choose only for legacy through-hole designs where SMT is unavailable and thermal cycling is non-critical. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CH uniquely combines 1500W surge capacity, sub-1ps response, AEC-Q101 qualification, and DO-214AB SMT compatibility - making it the only option for automated production of automotive-grade 200V bidirectional TVS protection.

FAQ
What is the clamping voltage of the 1.5SMC200CH under a standard 10/1000µs surge?
The 1.5SMC200CH clamps to a maximum of 287 V when subjected to its rated peak impulse current of 5.4 A under the 10/1000µs waveform defined in IEC 61000-4-5 and ISO 7637-2. This value is measured at TA = 25°C and reflects worst-case device behavior across process variation and temperature extremes.
Is the 1.5SMC200CH unidirectional or bidirectional?
The 1.5SMC200CH is a bidirectional TVS diode, indicated by the "CH" suffix per Taiwan Semiconductor's ordering nomenclature. It provides symmetrical clamping for both positive and negative transients, with identical VBR, VC, and IPPM specifications in either polarity - eliminating the need for polarity-aware PCB layout.
Does the 1.5SMC200CH meet AEC-Q101 requirements for automotive use?
Yes, the 1.5SMC200CH is explicitly AEC-Q101 qualified per the manufacturer's datasheet (Version B2207). It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - confirming suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum working stand-off voltage (VWM) for the 1.5SMC200CH?
The maximum working stand-off voltage (VWM) for the 1.5SMC200CH is 162 V. This is the highest DC or continuous peak voltage the device can withstand without exceeding 1 µA leakage current, establishing the upper limit for reliable operation in 200V-class systems.
How does the thermal performance of the 1.5SMC200CH compare to smaller SMT TVS packages?
The 1.5SMC200CH offers RθJA = 50°C/W and RθJC = 15°C/W - significantly better than DO-214AA (SMBJ) or SOD-123 packages due to its larger DO-214AB (SMC) footprint and exposed thermal slug. This enables higher sustained power dissipation and improved reliability in thermally constrained automotive and industrial PCB layouts.
