Product details
Overview
1.5KE10CARL4 from ON Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 8.55 V working peak reverse voltage (VRWM), 14.5 V clamping voltage at 103 A peak pulse current, and 1500 W peak pulse power rating per 1 ms waveform - deployed in power supplies, industrial controls, and medical equipment input stages.
For engineers reviewing the 1.5KE10CARL4 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, UL 497B-certified isolation loop protection capability, axial lead package dimensions, and real-world design guidance for surge immunity validation and PCB layout optimization.
Technical Context
The 1.5KE10CARL4 operates as a bidirectional Zener-based TVS, leveraging avalanche breakdown in both polarities to clamp transient overvoltages symmetrically around ground. Its 10.5 V nominal breakdown voltage (VBR) at 1 mA test current and <1 ns response time enable effective suppression of fast-rising transients without signal distortion.
Thermal performance is defined by 20 °C/W junction-to-lead thermal resistance and 5.0 W steady-state power dissipation at 75 °C lead temperature. The device meets Class 3 ESD immunity (>16 kV HBM) and is UL 497B recognized for isolated loop circuit protection - critical for telecom interfaces and sensor front-ends requiring certified surge resilience.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8.55 V - maximum continuous reverse operating voltage; must exceed system DC bus or signal swing to avoid leakage conduction |
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V @ 1 mA - defines precise clamping onset threshold under standardized test conditions |
| VC @ IPP | 14.5 V @ 103 A - peak clamped voltage during 1 ms 8/20 μs surge; determines maximum stress on downstream ICs |
| PPK | 1500 W @ 1 ms - peak surge energy handling capacity; validates suitability for IEC 61000-4-5 Level 4 compliance testing |
| IR @ VRWM | 10 μA - low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| Response Time | <1 ns - enables suppression before transient energy couples into protected circuitry; critical for high-speed data lines |
| ESD Rating | Class 3 (>16 kV HBM) - exceeds IEC 61000-4-2 requirements for user-accessible ports and connectors |
Pinout & Package
1.5KE10CARL4 uses an axial-leaded plastic package (Case 41A), with no polarity marking required for bidirectional operation - cathode band is non-functional. Leads are solderable per 230 °C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; connects to line or signal path requiring bidirectional clamping |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; ties to same node as anode for symmetrical protection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal paths without polarity constraints |
| UL 497B recognition | Validates compliance for isolated loop protection in telecom, process control, and safety-critical instrumentation |
| Low dynamic impedance | Minimizes voltage overshoot during fast transients; supports robust protection in high-dI/dt environments |
| Void-free molded case | Ensures long-term reliability under thermal cycling and humidity exposure in industrial enclosures |
| Corrosion-resistant finish | Guarantees solderability and intermetallic bond integrity after extended storage or harsh environment exposure |
Applications
| Industrial Power Supply Input | Medical Equipment EMI Filter Stage |
|---|---|
Use Scenario: AC/DC adapter input stage exposed to lightning-induced surges on mains lines. IC Role / Device Role / Timing Role: Primary-level transient clamp placed across L-N or L/N-GND to limit surge energy entering rectifier and bulk capacitor. Use Value: 1500 W peak power rating and 14.5 V clamping voltage prevent overvoltage failure of bridge rectifier and primary-side controller ICs. |

Use Scenario: T1/E1 line driver output connected to external wiring susceptible to induced surges. IC Role / Device Role / Timing Role: Protection element on balanced differential pair prior to transformer coupling. Use Value: Low capacitance and matched bidirectional clamping preserve signal integrity while meeting GR-1089-CORE Level 3 surge thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | 600 W PPK, SMC package, 17.0 V VC @ 32.1 A | Lower surge rating; suited for space-constrained PCBs where 1500 W is not required | Select SMBJ10CA when board area is limited and peak surge currents remain below 35 A |
| 1.5KE10A | Unidirectional variant; same VRWM/VBR but conducts only in one polarity | Requires explicit polarity assignment; used where DC bias prevents reverse conduction | Choose 1.5KE10A only if circuit topology guarantees unidirectional transients and ground-referenced clamping |
Compared with SMBJ10CA and 1.5KE10A, the 1.5KE10CARL4 provides higher surge margin for industrial-grade systems, bidirectional flexibility for AC or floating nodes, and UL 497B certification - making it the preferred choice for certified, high-energy protection where axial lead mounting is acceptable.

FAQ
What is the clamping voltage of the 1.5KE10CARL4 under maximum surge conditions?
The 1.5KE10CARL4 has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current of 103 A, measured using the standard 1 ms exponential waveform. This value ensures downstream components see no more than 14.5 V during worst-case transients - a key parameter for validating protection margins in 12 V rail applications. The 1.5KE10CARL4 maintains this clamping performance across its qualified temperature range.
Is the 1.5KE10CARL4 suitable for UL 497B-certified isolated loop protection?
Yes, the 1.5KE10CARL4 is explicitly UL 497B recognized (File #116110, QVGV2 category) for isolated loop circuit protection - covering strike voltage breakdown, endurance conditioning, and dielectric withstand tests. This certification applies directly to the 1.5KE10CARL4 as part of the 1.5KE6.8CA–1.5KE250CA series, enabling use in telecom interfaces and medical isolation barriers without additional qualification.
How does the bidirectional nature of the 1.5KE10CARL4 affect PCB layout compared to unidirectional TVS diodes?
The 1.5KE10CARL4 requires no orientation during placement - its bidirectional structure eliminates polarity concerns, simplifying assembly and reducing risk of misplacement. Unlike unidirectional variants such as 1.5KE10A, it clamps equally on positive and negative transients without external biasing. This allows direct placement across AC-coupled lines or floating sensor outputs, and avoids the need for dual-diode configurations in differential protection schemes.
What is the maximum steady-state power dissipation rating for the 1.5KE10CARL4?
The 1.5KE10CARL4 is rated for 5.0 W steady-state power dissipation at a lead temperature (TL) of 75 °C, with linear derating above that temperature at 20 mW/°C. This rating assumes 3/8″ lead length and defines safe continuous operation limits - distinct from its 1500 W peak pulse rating. Engineers must verify ambient and thermal conditions to ensure TL remains within −65 °C to +175 °C operating range during sustained fault conditions.
Does the 1.5KE10CARL4 meet ESD immunity standards for end-user accessible ports?
Yes, the 1.5KE10CARL4 is rated Class 3 per Human Body Model (HBM) with >16 kV ESD immunity - exceeding IEC 61000-4-2 Level 4 requirements. This performance is validated per JEDEC JESD22-A114 and supports robust protection of USB, RS-485, and other user-facing interfaces. The 1.5KE10CARL4 achieves this through low zener impedance and fast avalanche response, not external circuitry.
