Product details
Overview
P6KE22CARL from ON Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning surges, and inductive switching transients. It features a 22 V nominal breakdown voltage (VBR), 30.6 V maximum clamping voltage (VC) at 20 A peak pulse current, 600 W peak pulse power rating (1 ms), and <1 ns response time - deployed in power supplies, industrial controls, and medical equipment input stages.
For engineers reviewing the P6KE22CARL datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (18.8 V), clamping performance under 20 A surge, UL 497B recognition for isolated loop protection, low zener impedance, and axial leaded Surmetic−40 package compatibility with through-hole PCB assembly.
Technical Context
The P6KE22CARL operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence - cathode band marking is non-functional. Its silicon junction exhibits low dynamic impedance during conduction, enabling rapid voltage limiting within nanoseconds of transient onset.
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD immunity (>16 kV HBM). Thermal design relies on junction-to-lead resistance (20 °C/W) and derating above 75 °C ambient, with steady-state dissipation limited to 5 W at TL ≤ 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage (VRWM) | 18.8 V - maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (VBR) | 20.9–23.1 V @ 1 mA - defines precise avalanche onset threshold |
| Clamping Voltage (VC) | 30.6 V @ 20 A IPP - maximum voltage seen by protected circuit during full-rated surge |
| Peak Pulse Power (PPK) | 600 W @ 1 ms - energy-handling capacity for standardized 8/20 µs surge waveform |
| Response Time | <1 ns - ensures suppression occurs before transient propagates into downstream ICs |
| Leakage Current (IR) | <5 µA @ 18.8 V - negligible standby power loss and signal interference |
| ESD Rating (HBM) | Class 3 (>16 kV) - exceeds IEC 61000-4-2 Level 4 for system-level robustness |
Pinout & Package
Package: Axial-leaded Surmetic−40 plastic case (Case 17), void-free thermosetting material, corrosion-resistant leads, rated for 230 °C soldering (10 s at 1/16″ from case).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during negative transient | One end of symmetrical PN junction - no functional polarity; interchangeable with cathode |
| Cathode | Current entry during positive transient | Opposite end of same junction - cathode band is mechanical marker only, not electrical polarity indicator |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or floating DC rails without external polarity management |
| UL 497B recognition | Validated for use in isolated loop telecom and industrial interfaces requiring certified surge protection |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage stress on downstream components during worst-case surge events |
| Surmetic−40 axial package | Provides mechanical robustness, high thermal mass for surge energy absorption, and compatibility with legacy through-hole assembly |
| Temperature coefficient of VBR | 0.092 %/°C - enables predictable voltage drift across −55 °C to +175 °C operating range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | Surface-mount SMB package; 600 W rating; slightly higher VC (33.2 V @ 17.1 A) | Requires rework for SMT assembly; lower thermal mass than axial leaded P6KE22CARL | Select when board space is constrained and automated assembly is prioritized over manual repairability |
| 1.5KE22CA | Same axial package but 1500 W rating; higher VC (36.2 V @ 41.4 A); larger case (Case 5A) | Over-spec'd for 600 W needs; requires larger PCB footprint and higher cost | Select only if future surge margin expansion or legacy 1.5 kW design reuse is required |
Compared with SMBJ22CA and 1.5KE22CA, the P6KE22CARL offers optimal balance of proven axial-leaded reliability, UL 497B certification, and precise 30.6 V clamping - making it preferred for industrial through-hole designs where serviceability and surge consistency matter more than miniaturization.

FAQ
What is the clamping voltage of the P6KE22CARL under maximum surge conditions?
The P6KE22CARL has a maximum clamping voltage (VC) of 30.6 V when subjected to its rated 20 A peak pulse current (IPP) with a 1 ms exponential waveform. This value is measured per Figure 3 in the official datasheet and represents the highest voltage the protected circuit will experience during a full 600 W transient event. The P6KE22CARL maintains this clamping performance across its specified operating temperature range.
Is the P6KE22CARL suitable for bidirectional AC line protection?
Yes, the P6KE22CARL is explicitly designed as a bidirectional TVS diode - its CA suffix denotes symmetrical clamping for both polarities. The cathode band is a mechanical marker only and does not indicate functional polarity. This makes the P6KE22CARL appropriate for protecting AC-coupled signals, transformer-isolated interfaces, and floating DC buses where transients may swing positive or negative relative to ground.
Does the P6KE22CARL have UL recognition for safety-critical applications?
Yes, the P6KE22CARL carries UL 497B recognition (File #E116110, category QVGV2) for isolated loop circuit protection - confirmed in the official ON Semiconductor documentation. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing, distinguishing it from competitors with only flammability-rated packages. The P6KE22CARL's UL listing applies directly to its bidirectional CA configuration.
What is the maximum steady-state power dissipation for the P6KE22CARL?
The P6KE22CARL has a steady-state power dissipation (PD) of 5 W at lead temperature (TL) ≤ 75 °C with 3/8″ lead length. Above 75 °C, it derates linearly at 50 mW/°C, reaching zero dissipation at 175 °C. This rating assumes proper heat sinking via leads and is distinct from its 600 W peak pulse capability - the P6KE22CARL is not intended for continuous power regulation.
How does the P6KE22CARL's response time impact circuit protection effectiveness?
The P6KE22CARL has a typical response time of less than 1 ns, meaning it begins clamping within one nanosecond of transient voltage exceeding its breakdown threshold. This speed prevents most fast-rising ESD and lightning-induced spikes from propagating into sensitive downstream components. However, effective protection also depends on minimizing PCB trace inductance - the P6KE22CARL must be placed as close as possible to the protected node to avoid overshoot caused by external parasitics.
