Product details
Overview
1.5SMC200A from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It delivers 1500W peak pulse power, 274V clamping voltage at 5.7A peak current, and 171V working stand-off voltage in a DO-214AB (SMC) package - deployed in telecom line cards, industrial I/O modules, and automotive body control units.
For engineers reviewing the 1.5SMC200A datasheet, 1.5SMC200A pinout, 1.5SMC200A application, or 1.5SMC200A equivalent, key selection criteria include bidirectional clamping capability, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, <1μA leakage at 171V, and thermal resistance of 15°C/W junction-to-case - critical for sustained surge immunity in harsh ambient environments.
Technical Context
The 1.5SMC200A uses a glass-passivated silicon junction to achieve fast response (<1.0ps) and stable breakdown behavior across temperature. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity.
Rated for -55°C to +150°C junction operation, it features 50°C/W junction-to-ambient thermal resistance and meets JESD201 Class 2 whisker resistance. Electrical specs are validated per ANSI/IEEE C62.35 with 10/1000μs surge waveform compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias margin in protected circuitry |
| VBR min/max | 190–210 V @ 1 mA - verified breakdown threshold ensures predictable turn-on during transients; tight 10% tolerance supports precise system-level protection design |
| VC @ IPPM | 274 V @ 5.7 A - clamping voltage under 10/1000μs surge limits downstream device stress to ≤274 V, enabling robust interface IC survival |
| PPK | 1500 W - peak pulse power rating determines survivability against lightning-induced surges (IEC 61000-4-5 Level 4) and load dump events |
| IR @ VWM | <1 μA - ultra-low leakage preserves signal integrity and battery life in always-on monitoring circuits and low-power sensors |
| TJ max | +150 °C - high junction temperature rating allows operation in engine bay or industrial enclosures without derating |
| RθJC | 15 °C/W - low thermal resistance enables effective heat transfer to PCB copper pour or heatsink, sustaining repetitive surge duty cycles |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, polarity marked by cathode band (bidirectional use has no functional polarity marking).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge conduction path | Both terminals serve identical clamping function; no polarity dependency simplifies layout and eliminates orientation errors in automated assembly |
| Case (body) | Thermal and mechanical interface | DO-214AB body provides 0.210g mass and UL 94V-0 molding compound - contributes to thermal inertia and flame-retardant safety compliance |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over time and temperature, eliminating parameter drift in 15-year industrial deployments |
| ISO 7637-2 compliance (Pulse 1/2a/2b/3a/3b) | Validated for automotive ECU protection against battery transients including load dump and alternator ripple coupling |
| Moisture sensitivity level 1 (J-STD-020) | Enables direct placement without baking or dry-pack handling - reduces manufacturing cost and process risk |
| Halogen-free (IEC 61249-2-21) & RoHS compliant | Meets global environmental regulations for consumer, telecom, and industrial end equipment without material substitution trade-offs |
| Fast response time <1.0 ps | Clamps ESD events (IEC 61000-4-2 ±8 kV contact) before sensitive logic or analog front-ends experience latch-up or damage |
Applications
| Industrial PLC Analog Inputs | Automotive Body Control Module (BCM) Power Lines |

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 (Bourns) | Same DO-214AA package, 1500 W rating, but 200 V nominal VBR; slightly lower clamping (273 V @ 5.7 A) and higher leakage (5 μA @ 162 V) | Preferred where tighter VBR tolerance is required and higher IR is acceptable in low-power standby modes | Select SMBJ200A when footprint compatibility with SMB package is mandatory and thermal budget allows higher RθJA (65°C/W vs. 50°C/W) |
| SMCJ200A (Littelfuse) | Identical DO-214AB package and 1500 W rating; VBR 190–210 V same as 1.5SMC200A, but clamping voltage 275 V @ 5.7 A and RθJC 16°C/W | Used in aerospace-grade designs requiring AEC-Q200 qualification and extended lifetime validation data | Choose SMCJ200A for programs requiring full AEC-Q200 test reports and traceable lot history, accepting marginal thermal penalty |
Compared with SMBJ200A and SMCJ200A, the 1.5SMC200A offers superior leakage performance (<1 μA), lower junction-to-case thermal resistance (15°C/W), and J-STD-020 Level 1 moisture sensitivity - making it optimal for high-reliability, high-volume industrial and automotive production where assembly yield and long-term parametric stability are critical.

FAQ
What is the clamping voltage of the 1.5SMC200A under standard 10/1000μs surge conditions?
The 1.5SMC200A exhibits a maximum clamping voltage of 274 V at 5.7 A peak impulse current (IPPM) under the standardized 10/1000μs double-exponential waveform. This value is measured per ANSI/IEEE C62.35 and guarantees downstream circuit protection within defined voltage margins during surge events.
Is the 1.5SMC200A suitable for bidirectional signal line protection?
Yes, the 1.5SMC200A is explicitly rated for bidirectional use, with identical electrical characteristics in both directions. Its symmetrical breakdown (190–210 V) and clamping behavior make it ideal for protecting AC-coupled interfaces like RS-485, CAN FD, or telecom line pairs without polarity constraints.
Does the 1.5SMC200A meet automotive surge immunity standards?
Yes, the 1.5SMC200A is tested and compliant with ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b - covering conducted transients from battery disconnection, inductive load switching, and capacitive coupling in 12 V automotive systems. It is widely used in BCM and infotainment power rail protection.
What is the maximum steady-state power dissipation for the 1.5SMC200A at 25°C ambient?
The 1.5SMC200A has a steady-state power dissipation (PD) rating of 6.5 W at TA = 25°C. This value reflects continuous DC power handling capability and must be derated linearly above 25°C using the 50°C/W junction-to-ambient thermal resistance specified in the datasheet.
How does the 1.5SMC200A compare to unidirectional TVS diodes in terms of leakage current?
The 1.5SMC200A maintains <1 μA blocking leakage current at its 171 V working stand-off voltage - matching the performance of high-end unidirectional TVS diodes in the same voltage class. This ultra-low IR supports precision analog sensing and battery-powered applications where quiescent current is critical.
