Product details
Overview
1.5SMC200 from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 1500W peak pulse power, 200V breakdown voltage (VBR = 180–220V), and 287V maximum clamping voltage (VC) at 5.4A peak impulse current - used to protect DC power rails and signal lines in industrial power supplies against lightning-induced surges and load-switching transients.
For engineers reviewing the 1.5SMC200 datasheet, 1.5SMC200 pinout, 1.5SMC200 application, or 1.5SMC200 equivalent, key selection criteria include its 162V working stand-off voltage (VWM), <1μA leakage at VWM, 1.0ps typical response time, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and DO-214AB thermal performance (RθJC = 15°C/W).
Technical Context
The 1.5SMC200 operates as a unidirectional avalanche diode with glass-passivated junction, designed for single-polarity DC line protection where reverse-bias clamping is required. Its electrical behavior follows the IEEE C62.35 standard, with breakdown tested at 1.0mA IT and clamping verified under 10/1000μs waveform per REA definition.
Thermal design relies on its DO-214AB package's low junction-to-case resistance (15°C/W) and 150°C maximum junction temperature, enabling sustained operation in ambient temperatures up to +125°C when derated per Fig.2. It exhibits a VBR temperature coefficient of 0.108%/°C and forward voltage of 5.0V at 50A (per family note).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 180V / 220V - defines minimum and maximum voltage at which avalanche conduction begins reliably at 1.0mA test current |
| VWM | 162.0V - maximum continuous reverse operating voltage before significant leakage; sets safe DC rail margin |
| VC @ IPPM | 287V at 5.4A - clamped voltage during 10/1000μs surge; determines protected circuit's peak overvoltage stress |
| PPK | 1500W - peak pulse power handling per single non-repetitive event; defines surge energy absorption capacity |
| IR @ VWM | <1μA - reverse leakage at stand-off voltage; ensures minimal standby power loss and signal integrity |
| Response Time | <1.0ps - time from surge onset to clamping activation; guarantees protection before sensitive ICs experience overstress |
| TJ max | +150°C - maximum allowable junction temperature; constrains PCB copper area and airflow requirements |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, unidirectional configuration with cathode band marking. Case meets UL 94V-0 flammability rating; matte tin-plated leads comply with J-STD-002 solderability.

| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., +24V rail); conducts surge current to ground when VAK exceeds VBR |
Key Features
| Feature | Design Value |

Applications
| Industrial Power Supply Protection | Telecom Line Interface |
|---|---|
Use Scenario: Protecting 24V/48V DC input rails in programmable logic controllers (PLCs) and motor drives from inductive switching spikes and EFT bursts. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp transients before they reach upstream DC-DC converters and microcontrollers. Use Value: With VWM = 162V and VC = 287V, it safeguards 200V-rated input capacitors and MOSFETs while maintaining >1.2× margin over nominal 24V/48V systems. | Use Scenario: Shielding RS-485/RS-232 data lines in base station remote radio units (RRUs) from induced surges due to nearby lightning activity. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; 1.5SMC200 used only on DC bias rails feeding line drivers, not signal paths. Use Value: 1.0ps response ensures clamping occurs before 10/1000μs transients exceed receiver absolute maximum ratings - critical for maintaining link uptime in outdoor telecom infrastructure. |
| Automotive Body Control Module (BCM) | Renewable Energy Inverter DC Link |
Use Scenario: Guarding 12V battery-fed circuits in BCMs against load-dump and jump-start transients per ISO 7637-2. IC Role / Device Role / Timing Role: Mounted directly at connector entry point to shunt surge energy to chassis ground before reaching CAN transceivers and power management ICs. Use Value: Certified to ISO 7637-2 Pulse 5a (load dump) enables direct integration without additional filtering stages - reducing BOM count and board space. | Use Scenario: Suppressing switching transients on 300–400V DC link buses in solar string inverters caused by IGBT turn-off oscillations. IC Role / Device Role / Timing Role: Parallel-connected across DC bus capacitors to limit voltage overshoot during rapid current changes. Use Value: 1500W rating and 287V clamping allow reliable operation at 350V nominal bus voltage with 20% safety margin - preventing IGBT desaturation and capacitor overvoltage failure. |
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, DO-214AA package, 274V clamping at 3.1A | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a | Select only if system-level surge energy is ≤600W and layout space restricts DO-214AB footprint |
| 1.5KE200A | Through-hole TO-218 package, same 200V VBR, 287V VC, but 1500W rating | Requires wave soldering or hand assembly; incompatible with fully SMT production | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs automation benefits |
Compared with SMBJ200A and 1.5KE200A, the 1.5SMC200 delivers identical clamping performance in a smaller, automated-placement-ready DO-214AB package - offering superior thermal resistance (RθJC = 15°C/W vs. ~25°C/W for SMBJ) and full ISO 7637-2 compliance without derating.

FAQ
What is the maximum clamping voltage of the 1.5SMC200 under standard 10/1000μs surge conditions?
The 1.5SMC200 has a maximum clamping voltage (VC) of 287V at 5.4A peak impulse current (IPPM) under the standardized 10/1000μs double-exponential waveform defined by R.E.A. This value is measured at TA = 25°C and ensures predictable overvoltage limiting for downstream components in DC power systems.
Is the 1.5SMC200 suitable for bidirectional transient suppression?
No - the 1.5SMC200 is a unidirectional TVS diode intended for DC line protection with defined anode/cathode polarity. For bidirectional applications, Taiwan Semiconductor specifies the 1.5SMC200A variant (marked GTJ), which provides symmetrical clamping in both polarities and uses the same DO-214AB package.
What is the working stand-off voltage (VWM) of the 1.5SMC200, and how does it relate to system voltage?
The 1.5SMC200 has a working stand-off voltage (VWM) of 162.0V, meaning it remains non-conductive below this DC or RMS voltage. This allows safe use on 150V DC systems with ≥12V margin, preventing false triggering while ensuring fast response when transients exceed VWM.
Does the 1.5SMC200 meet automotive surge immunity standards?
Yes - the 1.5SMC200 meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), making it suitable for 12V/24V automotive subsystems including body control modules and infotainment power rails.
What is the thermal resistance from junction to case (RθJC) for the 1.5SMC200, and why does it matter in PCB layout?
The 1.5SMC200 has a junction-to-case thermal resistance (RθJC) of 15°C/W. This low value means efficient heat transfer from the silicon die to the PCB copper pad, allowing higher surge duty cycles and improved reliability in compact layouts - especially critical when multiple TVS devices share thermal mass or operate near temperature-sensitive components.
