Product details
Overview
P6KE15CARL from STMicroelectronics is a bidirectional transient voltage suppression (TVS) diode in DO-15 package, designed for IEC 61000-4-2 ESD and IEC 61000-4-4 surge protection. It features a standoff voltage (VRM) of 13 V, minimum breakdown voltage (VBR) of 14.3 V at 1 mA, clamping voltage (VCL) of 21.2 V at 28 A (10/1000 µs), and peak pulse power rating of 600 W. It is used in DC power input lines of industrial controllers and telecom interface circuits to suppress fast transients.
For engineers reviewing the P6KE15CARL datasheet, P6KE15CARL pinout, P6KE15CARL application, or P6KE15CARL equivalent, key selection criteria include bidirectional polarity, 13 V reverse standoff, 21.2 V clamping at 28 A, junction temperature range up to +175 °C, and DO-15 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it exhibits <0.5 µA leakage at 13 V; during transient events exceeding VBR, it avalanches to clamp voltage within nanoseconds. Its planar junction structure ensures low dynamic resistance (RD = 0.193 Ω) and stable performance across –55 °C to +175 °C operating junction temperature.
The device complies with IEC 61000-4-2 (30 kV air/contact discharge) and IEC 61000-4-4 level 4 (4 kV), delivering repeatable clamping behavior for 10/1000 µs surges up to 600 W and 8/20 µs surges up to 4 kW - validated per JEDEC JESD22-A114 and MIL-STD-883 Method 3015.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRM) | 13 V - maximum continuous reverse working voltage before leakage exceeds 0.5 µA; defines safe operating margin below breakdown. |
| Breakdown Voltage (VBR) | 14.3 V min @ 1 mA - guaranteed avalanche initiation threshold; ensures predictable turn-on during overvoltage events. |
| Clamping Voltage (VCL) | 21.2 V @ 28 A (10/1000 µs) - maximum voltage seen by protected circuit during rated surge; determines downstream component stress. |
| Peak Pulse Power (PPP) | 600 W @ 10/1000 µs - energy-handling capability at standard surge waveform; validates robustness against common lightning-induced transients. |
| Junction Temperature Range | –55 °C to +175 °C - enables deployment in high-ambient environments like industrial motor drives and outdoor telecom enclosures. |
| Dynamic Resistance (RD) | 0.193 Ω - low incremental resistance during conduction; minimizes clamping voltage rise under increasing surge current. |
| Leakage Current (IRM) | ≤0.5 µA @ VRM - ultra-low off-state current preserves battery life and avoids false triggering in low-power sensor nodes. |
Pinout & Package
DO-15 (JEDEC DO-204AC) axial-leaded package with cathode band marking; leads are matte tin-plated for solderability and RoHS compliance. Body diameter 3.24 mm max, length 28.5 mm typ., lead diameter 0.80 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side terminal for bidirectional operation | Connects to reference plane (GND or signal return); forms symmetrical clamping path with cathode during either polarity surge. |
| Cathode (banded end) | High-side terminal for bidirectional operation | Marked end identifies polarity; in bidirectional configuration, both terminals behave identically under reverse or forward surge conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional surge suppression | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 175 °C maximum junction temperature | Supports placement near heat-generating components (e.g., power MOSFETs, SMPS transformers) without derating. |
| 0.193 Ω dynamic resistance | Reduces clamping voltage overshoot under high di/dt transients, improving protection margin for 3.3 V/5 V logic interfaces. |
| 30 kV ESD immunity (IEC 61000-4-2) | Meets industrial and medical equipment requirements for user-accessible ports and front-panel connectors. |
| UL 497B certification (QVGQ2.E136224) | Validates suitability for primary-side telecom surge protection in UL-listed communication equipment. |
Applications
| Industrial PLC I/O Modules | Telecom Line Interface Cards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA (Bourns) | DO-214AA package (SMB), 1500 W peak power (10/1000 µs), VBR = 16.7 V min, VCL = 24.4 V @ 61.5 A | Higher power rating but larger footprint; requires PCB re-layout for surface-mount compatibility | Select when surge energy exceeds 600 W or when SMT assembly is mandatory. |
| 1.5KE15CA (ON Semiconductor) | DO-201AD package, 1500 W peak power (10/1000 µs), VBR = 14.3 V min, VCL = 24.4 V @ 61.5 A, higher IRM (5.0 µA) | Larger body (5.6 mm Ø × 9.5 mm L), higher leakage limits use in ultra-low-power battery systems | Choose for legacy DO-201AD socket compatibility or where higher surge margin justifies larger size. |
Compared with SMBJ15CA and 1.5KE15CA, P6KE15CARL offers optimal balance of compact DO-15 form factor, 0.5 µA leakage, and proven 600 W surge handling - making it preferred for space-constrained through-hole designs requiring minimal standby current and industrial-grade thermal resilience.

FAQ
What is the polarity configuration of P6KE15CARL?
P6KE15CARL is a bidirectional TVS diode, meaning it provides symmetrical clamping for both positive and negative transients across its terminals. The "CA" suffix explicitly denotes bidirectional construction, unlike "A"-suffixed unidirectional variants that require correct anode/cathode orientation relative to ground.
Does P6KE15CARL meet UL 497B for telecom surge protection?
Yes - P6KE15CARL carries UL 497B file number QVGQ2.E136224, certifying its compliance for use in primary circuit protection of telecommunications equipment. This validation covers its ability to safely limit surge voltages on telephone line interfaces per UL's insulation and flammability requirements.
How does junction temperature affect clamping voltage in P6KE15CARL?
Clamping voltage increases linearly with junction temperature at a coefficient αT = 8.4 × 10⁻⁴ /°C. For example, at Tj = 125 °C, VCL rises by approximately 8.4% above its 25 °C value of 21.2 V - resulting in ~22.9 V clamping - a predictable shift accounted for in system-level worst-case analysis.
Can P6KE15CARL be used in parallel for higher surge current handling?
No - P6KE15CARL is not characterized for parallel operation. Its dynamic resistance mismatch and thermal coupling risks cause current imbalance during surges, potentially leading to single-device failure. For >28 A surge capability, select a higher-rated part like SMBJ15CA or use discrete external current-sharing resistors with derated margins.
