Product details
Overview
1.5SMC200AH 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 (190–210V), 171V working stand-off voltage, and clamps transients to ≤274V at 5.7A, protecting DC bus lines against ISO 7637-2 Pulse 1/2a/2b/3a/3b events.
For engineers reviewing the 1.5SMC200AH datasheet, 1.5SMC200AH pinout, 1.5SMC200AH application, or 1.5SMC200AH equivalent, this device is selected for robust bidirectional ESD and lightning surge immunity where fast response (<1.0ps), low leakage (<1µA @ 171V), and AEC-Q101 qualification are required in DO-214AB (SMC) packaging.
Technical Context
The 1.5SMC200AH is a single-die, bidirectional TVS diode with symmetrical avalanche clamping in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.108%/°C), enabling predictable performance across –55°C to +150°C operating range.
It meets ISO 7637-2 test pulses without external circuitry and achieves <1.0ps response time due to low-junction-capacitance design. Thermal resistance is rated at RθJC = 15°C/W and RθJA = 50°C/W, supporting reliable power dissipation in high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 190V / 210V - Ensures consistent avalanche initiation within ±5% tolerance at 1mA test current |
| VWM | 171V - Maximum continuous DC or RMS voltage the device blocks without leakage exceeding 1µA |
| VC@IPPM | ≤274V at 5.7A - Clamping voltage during 10/1000µs surge defines protected circuit's maximum overvoltage stress |
| PPK | 1500W - Peak pulse power rating per 1ms waveform, derated linearly above 25°C ambient |
| IR@VWM | <1µA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |

Applications
| Automotive Power Distribution | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protecting 24V/48V battery-fed ECUs, lighting modules, and body control units from load dump and alternator transients. IC Role / Device Role / Timing Role: Bidirectional TVS placed across power rail and chassis ground to clamp surges before they reach downstream regulators and microcontrollers. Use Value: Limits peak voltage to ≤274V during 1500W ISO 7637-2 Pulse 5a events, preventing latch-up or gate oxide damage in 3.3V/5V logic supplies. | Use Scenario: Safeguarding AC/DC input stages of variable-frequency drives and PLC power supplies against lightning-induced surges on factory mains. IC Role / Device Role / Timing Role: Primary-line TVS connected line-to-line and line-to-ground to absorb repetitive 6kV/3kA transients per IEC 61000-4-5. Use Value: Maintains <1µA leakage at 171V working voltage, avoiding unnecessary power loss while delivering 1500W clamping capacity for EN 61800-3 compliance. |
| Telecom DC Feeds | Renewable Energy Inverter DC Links |
Use Scenario: Shielding PoE-powered switches and remote radio units from ESD and induced transients on 48V DC distribution lines. IC Role / Device Role / Timing Role: Bidirectional suppression element mounted at board edge to shunt fast-rising ESD (IEC 61000-4-2) and switching noise into ground plane. Use Value: Sub-1ps response time ensures clamping initiates before sensitive PHY ICs experience overstress, preserving data integrity and link uptime. | Use Scenario: Guarding high-voltage DC bus connections in solar string inverters and battery energy storage systems against grid-switching transients. IC Role / Device Role / Timing Role: Parallel-connected TVS on DC+ and DC− rails to equalize voltage imbalance and prevent IGBT gate driver damage during dV/dt events. Use Value: Symmetrical 190–210V VBR ensures matched clamping in both directions, critical for floating DC link topologies requiring balanced overvoltage protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | 600W rating, SMB package (smaller footprint), lower clamping voltage (275V) but reduced surge capacity | Lower power handling limits use to sub-1kW surge environments; not recommended for ISO 7637-2 Pulse 5a | Select when board space is constrained and peak surge energy is ≤600W |
| 1.5KE200A | Through-hole TO-204AA (DO-41), same 1500W rating but slower thermal response and no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive under-hood vibration environments | Select only for legacy through-hole designs or non-automotive industrial prototypes |
Compared with SMBJ200A and 1.5KE200A, the 1.5SMC200AH uniquely combines AEC-Q101 qualification, 1500W SMT capability, and bidirectional symmetry in DO-214AB - making it the preferred choice for production automotive and high-reliability industrial DC rail protection where automated assembly and standardized surge immunity are mandatory.

FAQ
What does the "AH" suffix indicate in 1.5SMC200AH?
The "AH" suffix in 1.5SMC200AH denotes the tighter VBR tolerance variant: 190–210V (±5%) versus the standard "H" version's 180–220V (±10%). This tighter specification ensures more precise clamping behavior in safety-critical applications such as automotive ECUs, where consistent overvoltage limiting is essential. The 1.5SMC200AH also features enhanced temperature coefficient control (0.108%/°C) and is explicitly qualified to AEC-Q101.
Is 1.5SMC200AH unidirectional or bidirectional?
1.5SMC200AH is a bidirectional TVS diode. Its electrical characteristics apply identically in both polarities, confirmed by the datasheet note: "Electrical characteristics apply in both directions" and the ordering instruction "For bidirectional use CH or CAH suffix for types 1.5SMC6.8H – 1.5SMC200AH". Unlike unidirectional variants, it has no cathode band marking and functions symmetrically across any two-terminal connection.
What is the maximum clamping voltage of 1.5SMC200AH at its rated peak pulse current?
The maximum clamping voltage (VC) of 1.5SMC200AH is 274V at IPPM = 5.7A, measured under the standard 10/1000µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range (–55°C to +150°C) and defines the highest voltage seen by downstream circuitry during a full-rated 1500W transient event.
Does 1.5SMC200AH meet automotive surge immunity standards?
Yes, 1.5SMC200AH meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements and is AEC-Q101 qualified. Its 1500W peak power rating, fast <1.0ps response, and stable VBR drift (0.108%/°C) enable robust protection against load dump, inductive switching, and capacitive coupling transients common in 12V/24V/48V automotive networks - verified per TSC's qualification report B2207.
What is the thermal resistance profile of 1.5SMC200AH?
The 1.5SMC200AH has a junction-to-case thermal resistance (RθJC) of 15°C/W and junction-to-ambient (RθJA) of 50°C/W at 25°C ambient, measured on a standard FR-4 PCB with 1-inch² 2-oz copper pad. These values support continuous power dissipation up to 6.5W and ensure safe operation under sustained surge duty cycles when mounted with adequate copper pour and airflow.
