Product details
Overview
P6KE150CARL from STMicroelectronics is a bidirectional 600 W transient voltage suppression diode in DO-15 package, designed for IEC 61000-4-2 ESD (30 kV air/contact) and IEC 61000-4-4 surge (4 kV level 4) protection. It features a 150 V breakdown voltage (VBR = 143–158 V), 207 V clamping voltage at 2.9 A (10/1000 µs), and operates up to +175 °C junction temperature. It is used in AC/DC power input stages of industrial power supplies and telecom line interfaces.
For engineers reviewing the P6KE150CARL datasheet, P6KE150CARL pinout, P6KE150CARL application, or P6KE150CARL equivalent, key selection criteria include bidirectional clamping capability, low dynamic resistance (7.13 Ω), high-temperature reliability, and compliance with UL 497B and IEC 61000-4-x immunity standards.
Technical Context
The P6KE150CARL is a planar-junction, silicon avalanche TVS diode optimized for fast response (<1 ns) to electrostatic discharge and repetitive surges. Its bidirectional structure enables symmetrical clamping across both polarities without external polarity management.
It delivers 600 W peak pulse power (10/1000 µs) at 25 °C, derating to 300 W at Tj = 175 °C, with leakage current <0.5 µA at VRM = 128 V and thermal resistance Rth(j-a) ≈ 4.5 °C/W on standard FR4 PCB with 5 cm² copper per lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 143 / 150 / 158 V - ensures reliable triggering above normal operating voltage while avoiding false trips during transients |
| VCL @ IPP = 2.9 A | 207 V - clamps surge energy below system-level overvoltage thresholds for downstream ICs |
| RD (dynamic resistance) | 7.13 Ω - determines voltage overshoot under fast-rising surges; lower value improves clamping precision |
| IPP (10/1000 µs) | 2.9 A - maximum surge current it can safely divert without degradation |
| Tj max | +175 °C - enables operation in high-ambient environments like enclosed power converters or outdoor telecom cabinets |
| ESD rating | ±30 kV (IEC 61000-4-2, contact & air) - exceeds industrial immunity requirements for front-panel interfaces |
| Surge rating | 4 kV (IEC 61000-4-4, level 4) - protects against induced lightning surges on AC mains or signal lines |
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 typ., length: 28.5 mm typ., lead diameter: 0.80 mm typ.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in forward bias; common reference for bidirectional clamping | Connected to protected line; forms symmetrical clamp path with cathode during either polarity surge |
| Cathode (banded end) | Current exit terminal in forward bias; defines polarity reference | Marked end identifies terminal; required for correct orientation in unidirectional variants; bidirectional use relies on symmetric junction design |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or differential signals without polarity constraints |
| Low dynamic resistance (7.13 Ω) | Minimizes clamping voltage rise under high di/dt surges, improving protection margin for 150 V-rated systems |
| High-temperature operation (Tj ≤ 175 °C) | Supports placement near heat-generating components (e.g., bridge rectifiers, MOSFETs) without derating penalties |
| UL 497B certified (QVGQ2.E136224) | Validates suitability for primary-side telecom and industrial surge protection per safety agency requirements |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow compatibility without dry-pack handling or baking |
Applications
| Industrial AC Power Input | Telecom Line Interface |
|---|---|
|
Use Scenario: Protection of AC mains inputs in programmable logic controllers (PLCs) and motor drives against lightning-induced surges and switching transients. IC Role / Device Role / Timing Role: Primary-level TVS device placed before bridge rectifier to clamp line-to-line and line-to-ground surges. Use Value: Withstands 4 kV IEC 61000-4-4 surges and maintains <0.5 µA leakage at 128 V, preventing standby power loss and ensuring long-term reliability. |
Use Scenario: Surge protection on analog telephone line interfaces (POTS) in VoIP gateways and remote terminal units. IC Role / Device Role / Timing Role: Bidirectional clamping element across tip/ring pair to suppress longitudinal surges while preserving signal integrity. Use Value: Symmetrical 207 V clamping limits differential overvoltage to safe levels for SLIC and codec ICs without requiring external polarity control. |
| Medical Equipment Mains Filter | Smart Meter Power Supply |
|
Use Scenario: Secondary-stage transient suppression in Class I medical AC-DC power supplies meeting IEC 60601-1 creepage/clearance and immunity requirements. IC Role / Device Role / Timing Role: Post-EMI filter TVS that absorbs residual surges escaping upstream filtering, reducing stress on Y-capacitors and isolation barriers. Use Value: UL 497B certification and 175 °C Tj rating support safety-critical designs where thermal margin and regulatory traceability are mandatory. |
Use Scenario: Input protection for single-phase smart meters exposed to utility grid transients and neutral-ground faults. IC Role / Device Role / Timing Role: First-line defense on AC input terminals, coordinated with MOVs to handle high-energy surges while providing fast-response clamping. Use Value: 30 kV ESD rating and low capacitance (<50 pF at 1 MHz) prevent interference with metering accuracy and communication modules (e.g., PLC or RF). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same VBR range (143–158 V), but SMC package (higher IPP = 5.2 A, lower RD = 4.2 Ω), 600 W rating at 25 °C only | Requires PCB real estate for SMC footprint; better suited for higher-current surges but less compatible with legacy DO-15 layouts | Select when surge current >3 A is expected and board space allows SMC mounting |
| 1.5KE150CA | Higher peak power (1500 W), same DO-15 package, but larger body (DO-201AD), VBR = 143–158 V, VCL = 207 V, RD = 6.8 Ω | Physically incompatible with DO-15 footprints; requires mechanical redesign; intended for higher-energy threat environments | Select only if system-level testing confirms need for >600 W surge handling and layout permits larger case |
Compared with SMBJ150CA and 1.5KE150CA, P6KE150CARL offers optimal balance of DO-15 compatibility, 175 °C operation, and UL 497B certification-making it preferred for space-constrained, thermally demanding, and safety-certified industrial designs where exact footprint retention is critical.

FAQ
What is the difference between P6KE150A and P6KE150CARL?
P6KE150A is unidirectional (anode-cathode asymmetry), while P6KE150CARL is bidirectional (symmetrical clamping). The "C" suffix denotes bidirectional construction, and "RL" indicates tape-and-reel packaging (6000 units/reel). Both share identical VBR, VCL, and power ratings, but only the CA version protects AC or differential lines without polarity concerns.
Can P6KE150CARL replace a MOV in AC input protection?
No-it is not a direct MOV replacement. MOVs handle higher energy (joules) at slower rates; P6KE150CARL provides faster clamping (nanoseconds) but lower total energy absorption. It is typically used downstream of MOVs or in coordination with them to suppress residual fast transients that MOVs cannot clamp quickly enough.
Is P6KE150CARL suitable for DC 120 V bus protection?
Yes-its 150 V VBR and 207 V VCL provide appropriate margin above 120 V DC nominal, with <0.5 µA leakage at 128 V. It is commonly used in DC-powered industrial controls and railway auxiliary supplies where bidirectional fault tolerance and high-temperature stability are required.
Does P6KE150CARL require heatsinking?
No discrete heatsink is needed. Its DO-15 package achieves Rth(j-a) ≈ 4.5 °C/W with 5 cm² copper per lead on FR4. At 300 W dissipation (175 °C Tj), ambient must remain ≤120 °C. For continuous high-power surge duty, ensure ≥2 cm² copper pour per lead and avoid enclosure hotspots.
