Product details
Overview
P6KE16CARL from ON Semiconductor is a bidirectional 600 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning surges, and inductive switching transients. It features a 13.6 V working peak reverse voltage (VRWM), 16 V nominal breakdown voltage (VBR), 22.5 V maximum clamping voltage (VC) at 27 A peak pulse current, and sub-1 ns response time - deployed in power supplies, industrial controls, and medical equipment.
For engineers reviewing the P6KE16CARL datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected IC VDD, surge current handling at system-level threat waveforms (8/20 µs), UL 497B recognition for isolated loop protection, and axial-leaded Surmetic−40 package compatibility with through-hole PCB layouts.
Technical Context
The P6KE16CARL operates as a bidirectional Zener-based TVS, leveraging avalanche breakdown in both polarities to clamp transient overvoltages symmetrically across its terminals. Its low zener impedance and fast intrinsic response (<1 ns) enable effective suppression before downstream components experience overstress.
It is rated for nonrepetitive 600 W peak pulse power per 1 ms waveform (Figure 3), with thermal derating above 75°C lead temperature and steady-state dissipation limited to 5 W. UL 497B recognition confirms compliance for isolated loop circuit protection in telecom and industrial interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms - withstands IEC 61000-4-5 Level 4 surge (4 kV/2 Ω) without failure |
| Working Peak Reverse Voltage (VRWM) | 13.6 V - maximum continuous DC or peak AC voltage before clamping initiates |
| Breakdown Voltage (VBR) | 15.2–16.8 V @ 1 mA - ensures reliable turn-on margin above VRWM with tight tolerance |
| Clamping Voltage (VC) | 22.5 V @ 27 A - limits voltage seen by protected circuit during full-rated surge |
| Leakage Current | <5 µA @ 13.6 V - negligible standby power loss and signal integrity impact |
| Response Time | <1 ns - faster than most microcontroller I/O pin ESD immunity thresholds |
| ESD Rating | Class 3 (>16 kV HBM) - exceeds JEDEC JS-001 requirements for board-level robustness |
Pinout & Package
Surmetic−40 axial-leaded plastic package (Case 17), DO-15 outline, with cathode band marking indicating terminal polarity - though bidirectional operation means either lead may serve as anode or cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Transient current entry (negative polarity) | Connects to line or signal path requiring bidirectional overvoltage clamping |
| Cathode (Lead 2, banded) | Transient current entry (positive polarity) | Same physical function as Lead 1; band is mechanical marker only - no functional polarity in CA devices |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines, differential buses, or floating signals without polarity constraints |
| UL 497B recognition | Validated for isolated loop protection in telecom and industrial interfaces - reduces certification burden |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes voltage overshoot margin required between protected IC's absolute max rating and VRWM |
| Surmetic−40 construction | Void-free thermoset molding ensures long-term reliability under thermal cycling and humidity stress |
| ESD robustness | Class 3 HBM (>16 kV) supports handling in standard assembly environments without additional ESD safeguards |
Applications
| Industrial Power Supply Input Protection | Medical Equipment Signal Line Clamping |
|---|---|
Use Scenario: 24 V DC input rail exposed to load dump and relay coil flyback in PLC power modules. IC Role / Device Role / Timing Role: Parallel-connected TVS diode clamping transient energy before it reaches DC-DC controller and input filter capacitors. Use Value: Limits input voltage to ≤22.5 V during 27 A surges, preserving controller IC reliability and avoiding overvoltage lockout. | Use Scenario: Analog sensor interface (e.g., thermocouple or pressure transducer) in patient-monitoring devices connected to external leads. IC Role / Device Role / Timing Role: Bidirectional clamping element placed at front-end op-amp inputs to suppress ESD and defibrillator-induced transients. Use Value: Prevents op-amp latch-up or damage from >15 kV HBM events while maintaining <5 µA leakage for precision DC accuracy. |
| Telecom Isolated Loop Interface | Automotive Body Control Module (BCM) CAN Bus Protection |
Use Scenario: 48 V isolated RS-485 trunk line in building automation systems subject to lightning-induced surges. IC Role / Device Role / Timing Role: UL 497B-recognized TVS on isolated side of digital isolator, protecting transceiver against common-mode transients. Use Value: Meets UL requirement for protector classification, enabling system-level safety certification without custom test validation. | Use Scenario: CAN_H/CAN_L lines in BCM exposed to battery disconnect transients and ISO 7637-2 Pulse 1/2a/5a events. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at connector, shunting surge current away from CAN transceiver ESD cells. Use Value: Clamps to 22.5 V within <1 ns, preventing transceiver damage while maintaining CAN signal integrity up to 1 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Surface-mount SMB package; same VRWM (13.6 V), VC = 24.4 V @ 24.5 A; lower peak power (600 W same, but smaller thermal mass) | Requires SMT reflow process; better high-frequency response due to lower parasitic inductance | Select when board space is constrained and automated assembly is used; verify thermal relief pad design for 5 W steady-state dissipation. |
| P6KE16A | Unidirectional version; identical VRWM, VBR, VC, and package; lacks bidirectional symmetry - cathode must be oriented toward positive rail | Only suitable for DC-biased lines where polarity is fixed; cannot protect AC or floating signals | Choose only for unidirectional DC rails (e.g., +12 V supply); avoid in differential, AC, or isolated applications where P6KE16CARL's symmetry is essential. |
Compared with SMBJ16CA and P6KE16A, the P6KE16CARL provides through-hole mechanical robustness, UL 497B certification for isolated loops, and true bidirectional clamping - making it optimal for industrial and medical designs requiring field-serviceable, certified, polarity-agnostic protection.

FAQ
What is the clamping voltage of P6KE16CARL at its rated peak pulse current?
The P6KE16CARL has a maximum clamping voltage (VC) of 22.5 V at 27 A peak pulse current (IPP), measured using the 1 ms exponential waveform defined in Figure 3 of the datasheet. This value ensures protected circuits remain below critical overvoltage thresholds during standardized surge events such as IEC 61000-4-5.
Is P6KE16CARL suitable for bidirectional signal line protection?
Yes, P6KE16CARL is explicitly a bidirectional TVS diode (denoted by the "CA" suffix), enabling symmetrical clamping for AC-coupled, differential, or floating signal paths. Its breakdown and clamping behavior are identical in both polarities - confirmed by electrical characteristics tables and UL 497B recognition for isolated loop protection.
Does P6KE16CARL have UL recognition, and for what standard?
Yes, P6KE16CARL carries UL Recognition under UL 497B (File #E116110) for protector classification (QVGV2). This certification covers performance in isolated loop circuits, including strike voltage breakdown, endurance conditioning, and dielectric withstand - distinguishing it from parts with only flammability-only recognition.
What is the steady-state power dissipation rating for P6KE16CARL?
P6KE16CARL is rated for 5 W steady-state power dissipation at a lead temperature (TL) of ≤75°C with 3/8″ lead length. Derating is required above 75°C at 50 mW/°C, per the "Steady State Power Dissipation" specification in the Maximum Ratings table.
How does the "RL" suffix in P6KE16CARL affect packaging and ordering?
The "RL" suffix indicates tape-and-reel packaging: P6KE16CARL is supplied in 4000-unit reels, optimized for automated pick-and-place assembly. This differs from the "CA" variant (e.g., P6KE16CA), which ships in 1000-unit boxes for manual or semi-automated insertion.
