Product details
Overview
1.5KE200CARL from STMicroelectronics is a bidirectional Transil™ TVS diode designed for high-energy transient voltage suppression in DC power lines and signal interfaces. It delivers 1500 W peak pulse power (10/1000 µs), has a 200 V standoff voltage (VRM), 210 V maximum clamping voltage at 274 A IPP, and operates across -65 °C to +175 °C. It protects MOSFETs, microcontrollers, and industrial I/O circuits against ESD and lightning-induced surges.
For engineers reviewing the 1.5KE200CARL datasheet, 1.5KE200CARL pinout, 1.5KE200CARL application, or 1.5KE200CARL equivalent, key selection criteria include clamping ratio (VCL/VBR = 1.05), low dynamic impedance (5.5 Ω), UL 497B certification, and DO-201 package compatibility with high-current PCB layouts.
Technical Context
This device functions as a voltage-clamping surge protector using avalanche breakdown. Its bidirectional configuration enables symmetrical protection on AC-coupled or floating lines without polarity constraints. The 200 V nominal breakdown voltage (VBR = 190–210 V @ 1 mA) ensures precise triggering above system operating voltage while maintaining margin against false trips.
Thermal design relies on junction-to-leads thermal resistance of 20 °C/W and a maximum junction temperature of 175 °C. With 1.08 × 10⁻⁴ /°C voltage temperature coefficient, its VBR drift remains predictable over industrial temperature ranges, supporting stable protection thresholds in varying ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W (10/1000 µs): Sustains single lightning-surge events per IEC 61000-4-5 Level 4 without failure. |
| Standoff Voltage (VRM) | 200 V: Maximum continuous reverse voltage before leakage exceeds 1 µA - sets upper limit for protected circuit DC bias. |
| Clamping Voltage (VCL) | 274 V @ 274 A (10/1000 µs): Limits transient voltage seen by downstream ICs to safe levels during surge. |
| Breakdown Voltage (VBR) | 190–210 V @ 1 mA: Defines precise avalanche initiation threshold for repeatable protection timing. |
| Leakage Current (IRM) | 1 µA @ 200 V: Ensures negligible standby power loss and no interference with high-impedance sensor inputs. |
| Capacitance | 675 pF @ 0 V, 1 MHz: Low enough for <1 Mbps RS-485 or 24 V PLC analog I/O, but not suitable for USB or HDMI. |
| Package | DO-201: Through-hole axial lead package with 9.0 mm body length and 25.4 mm lead spacing - supports manual soldering and high-current trace routing. |
Pinout & Package
1.5KE200CARL uses the DO-201 package: epoxy-molded, axial-leaded, UL94 V0 rated, lead-free compliant. Dimensions: 8.5–9.5 mm length (A), 25.4 mm lead spacing (B), 4.8–5.3 mm diameter (C), 0.96–1.06 mm lead diameter (D). Leads are unmarked; polarity is non-applicable due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry point (positive half-cycle) | Conducts surge current into cathode during positive transients; identical electrical behavior to Lead 2. |
| Cathode (Lead 2) | Transient current return path (negative half-cycle) | Completes conduction path during negative transients; functionally interchangeable with Lead 1 in bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection on AC lines, transformer-coupled interfaces, or floating buses without external polarity management. |
| Low clamping factor (VCL/VBR ≈ 1.05) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V or 5 V logic interfacing with 24 V industrial supplies. |
| Fast response time (< 1 ns) | Activates before transient energy couples into sensitive nodes - essential for safeguarding high-speed ADCs and gate drivers. |
| UL 497B certified | Validated for telecom and industrial surge protection per ANSI/UL 497B Annex B - reduces compliance validation effort. |
| High surge current rating (274 A) | Withstands multiple 10/1000 µs surges up to 80% of rated IPP - extends service life in harsh electromagnetic environments. |
Applications
| Industrial PLC Analog Input Modules | DC Power Rail Protection (24 V/48 V) |
|---|---|

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 | Same VBR/VCL specs but SMB package (surface-mount); 600 W rating vs. 1500 W. | Lower power handling limits use to Level 2/3 surges; requires PCB space optimization. | Select when board area is constrained and surge threat level is ≤1 kV (IEC 61000-4-5). |
| 1.5SMC200CA | Same DO-214AB package; 1500 W rating but higher VCL (287 V @ 263 A) and larger footprint than DO-201. | Less optimal thermal path in high-density layouts; requires wider copper pours for heat dissipation. | Choose when existing designs use SMC footprints and require drop-in mechanical compatibility. |
Compared with SMBJ200CA and 1.5SMC200CA, 1.5KE200CARL offers superior surge endurance in through-hole industrial assemblies, tighter clamping ratio, and proven reliability in long-life field deployments - making it preferred for mission-critical 24 V control systems.

FAQ
What is the maximum allowable surge current for 1.5KE200CARL under IEC 61000-4-5 10/1000 µs waveform?
The device sustains 274 A peak pulse current at 274 V clamping voltage per the datasheet's Table 3. This corresponds to full 1500 W rating under standard 10/1000 µs test conditions. Derating applies above 25 °C ambient; at 75 °C, maximum IPP drops to ~220 A due to thermal limits.
Can 1.5KE200CARL be used in AC mains applications?
No - it is rated for DC or low-frequency AC signal/power lines only. Its 200 V VRM and 210 V VBR are insufficient for direct connection to 120/230 VAC mains. For AC line protection, use dedicated MOVs or higher-voltage TVS arrays with appropriate isolation and safety agency approvals.
How does the bidirectional configuration affect PCB layout compared to unidirectional TVS diodes?
Bidirectional operation eliminates polarity marking and orientation checks during assembly, reducing manufacturing errors. Layout requires symmetric trace routing to both leads since either terminal may conduct during positive or negative transients - unlike unidirectional types that demand strict anode/cathode placement relative to ground.
Is 1.5KE200CARL RoHS and REACH compliant?
Yes - the device carries ECOPACK®2 certification per STMicroelectronics' documentation, confirming lead-free terminations, halogen-free epoxy, and full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations are available via ST's product change notifications.
