Product details
Overview
P6KE220CA from Littelfuse is a bidirectional transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines, telecom interfaces, and industrial control inputs. It features a 198–242 V breakdown voltage (VBR), 344 V maximum clamping voltage (VC) at 1.7 A peak pulse current (IPPM), and 600 W peak pulse power dissipation with a 10/1000 µs waveform - deployed to safeguard sensitive analog front-ends and microcontroller I/O against ESD and lightning-induced surges.
For engineers reviewing the P6KE220CA datasheet, P6KE220CA pinout, P6KE220CA application, or P6KE220CA equivalent, key selection criteria include its bidirectional symmetry, DO-204AC axial package compatibility, UL 497B listing for telecom surge protection, and verified clamping performance under repetitive 0.01% duty cycle transients.
Technical Context
The P6KE220CA operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<5.0 ns for bidirectional types) and stable breakdown characteristics across -55°C to +175°C. Its bidirectional construction ensures symmetrical clamping in both polarities without external polarity management.
It delivers 600 W peak pulse power handling per 10/1000 µs waveform, with thermal derating above 25°C ambient and steady-state power dissipation of 5.0 W at 75°C lead temperature. Clamping voltage is specified at 344 V for 1.7 A IPPM, with low incremental surge resistance ensuring minimal voltage overshoot during fast-rising transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 198–242 V at 1 mA test current - defines minimum voltage at which avalanche conduction initiates in either direction |
| Stand-off Voltage (VWM) | 175 V - maximum continuous reverse operating voltage before significant leakage begins |
| Clamping Voltage (VC) | 344 V at 1.7 A IPPM - peak voltage seen by protected circuit during worst-case 10/1000 µs surge |
| Peak Pulse Power (PPPM) | 600 W - energy-handling capability for non-repetitive 10/1000 µs transients at 25°C |
| Leakage Current (ID) | <5 µA at 175 V - ensures negligible loading on 175 V DC bus under normal operation |
| Response Time | <5.0 ns - enables suppression of fast transients such as ESD (IEC 61000-4-2) and inductive switching spikes |
| Operating Temperature | -55°C to +175°C - supports deployment in automotive engine compartments and industrial motor drives |
Pinout & Package
Package: DO-204AC (axial-leaded, molded plastic body per JEDEC standard), 0.300" (7.6 mm) body length, 0.230" (5.8 mm) lead spacing, 0.034" (0.86 mm) lead diameter. No color band - bidirectional symmetry eliminates cathode/anode marking.

|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Identical electrical behavior in both directions; connected across protected line and return (e.g., tip/ring in telecom, +V/REF in sensor interface) |
| Lead 1 | Terminal A | Axial lead for PCB through-hole mounting; solderable per MIL-STD-750 Method 2026; withstands 265°C/10 s high-temp soldering |
| Lead 2 | Terminal B | Second axial lead; mechanically identical to Lead 1; no polarity dependency in circuit layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating differential lines without polarity concerns |
| UL 497B certification | Validated for telecom primary/secondary circuit protection per ANSI/IEEE C62.35, reducing compliance validation effort |
| Glass-passivated junction | Ensures long-term stability of VBR and low parameter drift over temperature and lifetime |
| 600 W surge rating | Supports Level 4 IEC 61000-4-5 (4 kV line-earth, 2 kV line-line) with margin in typical PCB layouts |
| Low clamping ratio (VC/VWM = 1.97) | Minimizes overvoltage stress on downstream ICs while maintaining robust margin above operating voltage |
Applications
| Telecom Line Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting xDSL or T1/E1 line drivers and receivers from lightning-induced surges on twisted-pair copper lines. IC Role / Device Role / Timing Role: Bidirectional TVS placed across tip/ring terminals upstream of isolation transformer and line driver IC.

IC Role / Device Role / Timing Role: Mounted directly at connector entry point, parallel to bulk input capacitor and upstream of DC/DC converter. Use Value: Withstands 600 W pulses up to 100 ms duration while limiting rail voltage to 344 V, avoiding overvoltage shutdown of PMICs. | Use Scenario: Shielding low-noise instrumentation amplifiers in patient-connected ECG or EEG modules from ESD events during handling or cable contact. IC Role / Device Role / Timing Role: Placed across differential sensor inputs (e.g., RA-LA leads), referenced to isolated analog ground. Use Value: Sub-5 ns response prevents ESD-induced amplifier saturation, preserving baseline stability and diagnostic accuracy per IEC 60601-1-2. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | DO-214AA surface-mount package; same VBR (198–242 V), slightly lower VC (328 V @ 1.8 A); 600 W rating | Requires SMT reflow process; better high-frequency impedance due to lower parasitic inductance | Select when board space is constrained and automated assembly is used; verify PCB thermal relief for 5 W steady-state dissipation. |
| 1.5KE220CA | Same DO-204AC package; higher 1500 W peak power; VC = 328 V @ 4.3 A; larger physical size (0.375" body) | Higher energy absorption for infrequent but severe surges (e.g., utility grid coupling); less suitable for compact telecom modules | Choose where surge repetition is rare but peak energy exceeds 600 W; confirm mechanical fit in existing DO-204AC footprint. |
Compared with SMBJ220CA and 1.5KE220CA, the P6KE220CA offers optimal balance of axial through-hole manufacturability, UL 497B compliance, and 600 W surge capacity in legacy telecom and industrial designs - making it preferred for cost-sensitive, high-volume, and repair-friendly deployments.

FAQ
What is the maximum clamping voltage of the P6KE220CA under a 10/1000 µs surge?
The P6KE220CA has a maximum clamping voltage (VC) of 344 V when subjected to a 1.7 A peak pulse current (IPPM) with a 10/1000 µs waveform at 25°C ambient. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on protected circuitry during standardized surge testing - critical for verifying compatibility with downstream ICs rated for ≤350 V absolute maximum.
Is the P6KE220CA certified for telecom surge protection standards?
Yes, the P6KE220CA is UL listed to ANSI/IEEE C62.35 and specifically certified under UL 497B (File E136766) for telecom primary and secondary circuit protection. This certification validates its performance against lightning-induced surges on telephone lines and confirms compliance with industry requirements for central office and customer premises equipment - a key differentiator versus generic TVS diodes lacking formal telecom listing.
What is the stand-off voltage (VWM) of the P6KE220CA, and why does it matter?
The stand-off voltage (VWM) of the P6KE220CA is 175 V - the maximum continuous DC or RMS voltage that can be applied without triggering significant avalanche conduction. This parameter ensures the device remains non-conductive during normal operation of 175 V systems (e.g., telecom battery feeds or industrial 150 V DC buses), minimizing leakage (<5 µA) and avoiding unnecessary power loss or false triggering in voltage-monitoring circuits.
How does the bidirectional nature of the P6KE220CA affect its PCB layout?
The P6KE220CA is inherently bidirectional, meaning its two axial leads are electrically symmetric with no anode/cathode designation - eliminating polarity concerns in PCB layout. Unlike unidirectional TVS diodes, it requires no orientation check during placement and can be mounted across any pair of differential or floating nodes (e.g., tip/ring, CAN_H/CAN_L, or sensor+/sensor−) without risk of reverse-bias damage or functional failure.
What is the operating temperature range of the P6KE220CA, and how does it impact reliability?
The P6KE220CA operates across -55°C to +175°C junction temperature, supporting deployment in harsh environments including automotive under-hood modules and industrial motor control cabinets. Its glass-passivated junction maintains stable breakdown voltage over this full range, and the 5.0 W steady-state power rating at 75°C lead temperature ensures reliable thermal performance when mounted on standard copper pads - directly contributing to long-term field reliability without derating penalties in most applications.
