Product details
Overview
1.5SMC200H from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. 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 automotive power supply rail protection.
For engineers reviewing the 1.5SMC200H datasheet, 1.5SMC200H pinout, 1.5SMC200H application, or 1.5SMC200H equivalent, key selection criteria include its DO-214AB (SMC) package, unidirectional polarity, 162V working stand-off voltage (VWM), <1μA leakage at rated VWM, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive transients.
Technical Context
The 1.5SMC200H uses a glass-passivated silicon junction optimized for fast transient response (<1.0 ps) and robust clamping under repetitive or single-event surges. Its unidirectional configuration provides low forward voltage (VF = 5.0V @ 50A) and supports bidirectional use only when paired with complementary devices or specified variants (e.g., 1.5SMC200AH).
Thermally, it features RθJA = 50°C/W and RθJC = 15°C/W, enabling reliable operation up to 150°C junction temperature. It meets AEC-Q101 qualification and JESD201 Class 2 whisker resistance, confirming suitability for automotive-grade production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180 V / 220 V - ensures reliable triggering above system operating voltage while accommodating process variation |
| VWM | 162 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC@IPPM | ≤287 V @ 5.4 A - clamping voltage during 10/1000 μs surge defines worst-case overvoltage seen by protected circuitry |
| PPK | 1500 W - peak pulse power handling capacity per single 1ms waveform per IEC 61000-4-5 |
| IR@VWM | <1 μA - ultra-low leakage preserves efficiency in high-impedance or battery-backed circuits |
| TJ max | +150 °C - enables placement near heat-generating components in engine control units or power converters |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline compatible with automated assembly and IPC-7351B footprints |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with matte tin-plated leads, cathode band marking polarity, 0.210 g weight, UL 94V-0 rated compound, and J-STD-002 solderability compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Connected to lower-potential side of protected line; enables low-VF conduction during reverse-surge clamping |
| Cathode | Current exit point; marked with band | Connected to higher-potential side (e.g., +12V rail); defines unidirectional clamping direction toward ground |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A | 600W rating, SMB package (smaller footprint), 200V VBR, bidirectional variant available | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a/b load dump | Select when space-constrained and peak power demand 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 environments | Select only for legacy through-hole designs or non-automotive industrial use |
Compared with SMBJ200A and 1.5KE200A, the 1.5SMC200H uniquely combines AEC-Q101 qualification, 1500W SMT capability, and ISO 7637-2 compliance - making it the only drop-in solution for next-gen automotive power modules requiring both high energy handling and surface-mount manufacturability.

FAQ
What is the clamping voltage of the 1.5SMC200H under standard 10/1000 μs surge conditions?
The 1.5SMC200H exhibits a maximum clamping voltage (VC) of 287 V when subjected to its rated peak impulse current of 5.4 A using the 10/1000 μs waveform defined in IEC 61000-4-5. This value is measured at TA = 25°C and confirms the device's ability to limit overvoltage on protected lines to a safe margin below typical 300V-rated capacitors and MOSFETs. The 1.5SMC200H maintains this performance across its full operational temperature range.
Is the 1.5SMC200H suitable for bidirectional transient protection?
No - the 1.5SMC200H is a unidirectional TVS diode intended for protection against positive-going transients on DC lines referenced to ground. For bidirectional applications (e.g., AC lines or data buses), the 1.5SMC200AH variant must be used. The 1.5SMC200H lacks symmetrical breakdown characteristics and will not clamp negative excursions beyond its forward voltage (~5.0 V), making it inappropriate for true bipolar surge scenarios.
Does the 1.5SMC200H meet automotive qualification standards?
Yes - the 1.5SMC200H is explicitly AEC-Q101 qualified and tested per the full stress-test schedule, including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock. It also complies with ISO 7637-2 for automotive electrical disturbances (Pulse 1, 2a, 2b, 3a, 3b), confirming suitability for under-hood and body-control module applications where reliability under thermal and electrical stress is mandatory. The 1.5SMC200H carries full traceability and lot-level test reports.
What is the maximum steady-state power dissipation of the 1.5SMC200H at room temperature?
The 1.5SMC200H has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25°C, derived from its thermal resistance (RθJA = 50°C/W) and maximum junction temperature (TJ = 150°C). This value applies only to continuous DC or low-frequency AC loading - not transient events. In practice, the device is operated well below this limit during normal blocking mode due to sub-μA leakage, and its 1500W peak rating governs surge-handling capability, not steady-state thermal design.
How does the 1.5SMC200H compare to the 1.5SMC200AH in terms of electrical performance?
The 1.5SMC200H and 1.5SMC200AH share identical peak pulse power (1500 W), breakdown voltage range (180–220 V), and clamping voltage (287 V), but differ in configuration: the 1.5SMC200H is unidirectional with cathode-band marking, while the 1.5SMC200AH is bidirectional and symmetric in both polarities. The 1.5SMC200AH replaces two unidirectional devices in AC-coupled or floating-line applications, whereas the 1.5SMC200H is optimized for cost-sensitive, ground-referenced DC rails where only positive transients require suppression.
