Product details
Overview
P6KE200CA from Littelfuse is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power lines and signal interfaces. It features a 200 V standoff voltage (VWM), 287 V maximum clamping voltage (VC) at 2.1 A peak pulse current, and 600 W peak pulse power handling per 10/1000 µs waveform - deployed in telecom line cards, industrial I/O modules, and AC/DC power supply inputs.
For engineers reviewing the P6KE200CA datasheet, P6KE200CA pinout, P6KE200CA application, or P6KE200CA equivalent, key selection criteria include bidirectional surge suppression capability, UL 497B listing for telecom protection, DO-204AC axial package compatibility, and verified clamping performance under repetitive transients up to 0.01% duty cycle.
Technical Context
The P6KE200CA operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<5.0 ns) and low incremental surge resistance. Its bidirectional structure provides symmetrical clamping in both polarities without external polarity management.
It delivers stable breakdown behavior across -55°C to +175°C junction temperature range and maintains <1 µA leakage above 10 V at 25°C ambient. The device is rated for 100 A non-repetitive forward surge (IFSM) and supports high-temperature soldering (265°C/10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 162 V - Maximum continuous reverse working voltage before clamping initiates |
| Breakdown Voltage (VBR) | 180–220 V at 1 mA test current - Ensures reliable turn-on margin above normal operating voltage |
| Clamping Voltage (VC) | 287 V at 2.1 A peak pulse - Limits downstream voltage stress during 10/1000 µs surge events |
| Peak Pulse Power (PPPM) | 600 W - Sustains single high-energy transients without degradation |
| Leakage Current (ID) | <1 µA at 162 V - Minimizes standby power loss in always-on circuits |
| Operating Temperature | -55°C to +175°C - Supports deployment in harsh industrial and automotive under-hood environments |
| UL Recognition | UL 497B, File E136766 - Certified for telecom primary/secondary circuit protection |
Pinout & Package
Package: DO-204AC (Axial-leaded, glass-passivated plastic body per JEDEC standard). Dimensions: 3.6 mm × 2.6 mm diameter, 25.4 mm minimum lead length, 0.4 g weight.

| Cathode (Lead 2) | Transient return path (bidirectional) | Electrically identical to Anode; no polarity marking required for CA suffix devices |
Key Features
| Feature | Design Value |
|---|---|

| UL 497B certified | Validated for telecom central office and customer premises equipment per ANSI/IEEE C62.35 |
| Low incremental surge resistance | Minimizes VC overshoot during high di/dt events, improving system-level ESD immunity |
Applications
| Telecom Line Interface Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protects RJ-11/RJ-45 ports on DSLAMs, VoIP gateways, and base station backhaul interfaces from induced lightning surges and AC power cross-talk. IC Role / Device Role / Timing Role: Primary shunt protector placed upstream of isolation transformers and line drivers. Use Value: UL 497B certification ensures compliance with Telcordia GR-1089-CORE; clamping at 287 V prevents damage to TI TPS6598x or ADI ADM305x line interface ICs. |
Use Scenario: Shields 4–20 mA current loop inputs in programmable logic controllers against field wiring faults and electrostatic discharge. IC Role / Device Role / Timing Role: First-stage overvoltage clamp before precision op-amps (e.g., AD8420) and ADC front-ends (e.g., ADS1256). Use Value: 2.1 A IPPM rating handles 1 kV/500 Ω surge tests (IEC 61000-4-5); low leakage avoids offset drift in µV-level measurement circuits. |
| AC/DC Power Supply Input Protection | Automotive Body Control Module (BCM) Inputs |
Use Scenario: Installed across bulk capacitor inputs of offline SMPS to suppress differential-mode surges from mains switching transients. IC Role / Device Role / Timing Role: Secondary surge limiter after MOVs, reducing let-through energy to bridge rectifiers and controller ICs. Use Value: 600 W rating complements 140 V MOVs; 287 V clamping prevents overvoltage stress on ON Semiconductor NCP1014 or Infineon ICE2PCS01. |
Use Scenario: Guards LIN bus and sensor inputs (e.g., ambient temp, door switch) in BCMs against load dump and ISO 7637-2 pulse 5a/b. IC Role / Device Role / Timing Role: Bidirectional clamp on unregulated 12 V rail prior to LDO regulators and microcontroller GPIOs. Use Value: -55°C to +175°C operation meets AEC-Q101 requirements; DO-204AC axial leads support automated through-hole assembly in high-vibration environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Surface-mount SMB package (3.5 mm × 3.5 mm), same 200 V VWM, 296 V VC at 2.0 A | Requires PCB re-layout; better thermal dissipation in compact designs but lower surge margin than axial P6KE | Select when board space is constrained and automated SMT assembly is preferred |
| 1.5KE200CA | Same DO-204AC package, higher 1500 W peak power, 296 V VC at 5.1 A, larger physical size (4.5 mm Ø) | Higher surge capacity suits utility meter or solar inverter inputs; less suitable for dense telecom line cards | Select when legacy 1.5 kW surge standards (e.g., IEC 61000-4-5 Ed.3) apply and footprint allows |
Compared with SMBJ200CA and 1.5KE200CA, the P6KE200CA offers optimal balance of axial-leaded manufacturability, UL-certified telecom compliance, and 600 W surge handling - making it ideal for cost-sensitive, high-volume telecom and industrial control applications where DO-204AC mounting is standardized.

FAQ
What is the clamping voltage of P6KE200CA at its rated peak pulse current?
The P6KE200CA has a maximum clamping voltage (VC) of 287 V at 2.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting during surge events - critical for protecting downstream components like op-amps and communication transceivers in the P6KE200CA's target applications.
Is P6KE200CA suitable for telecom applications requiring UL 497B certification?
Yes, the P6KE200CA is UL listed under file E136766 for Telecom application protection per UL 497B, covering both primary and secondary circuits. This certification validates its use in DSLAMs, VoIP gateways, and fiber access terminals - confirming that the P6KE200CA meets stringent safety and surge withstand requirements defined for telecom infrastructure equipment.
How does the bidirectional design of P6KE200CA affect its circuit implementation?
The P6KE200CA's bidirectional construction eliminates polarity sensitivity, allowing direct placement across any two points needing symmetrical overvoltage protection - such as AC signal lines or unregulated DC rails. Unlike unidirectional TVS diodes, the P6KE200CA requires no orientation check during assembly and provides identical clamping in both directions, simplifying layout and reducing BOM complexity in designs like LIN bus interfaces or transformer-coupled telecom lines.
What is the maximum steady-state power dissipation for P6KE200CA at 75°C lead temperature?
The P6KE200CA has a maximum steady-state power dissipation (PM(AV)) of 5.0 W at a lead temperature (TL) of 75°C, measured with 0.375" (9.5 mm) lead length on a 40 mm × 40 mm copper pad. This rating defines safe continuous power handling in thermally managed environments - important when using the P6KE200CA in high-ambient industrial controls or enclosed power supplies where sustained leakage or ripple-induced heating may occur.
Can P6KE200CA replace P6KE200A in existing designs?
No - P6KE200CA and P6KE200A are not interchangeable. P6KE200CA is bidirectional with symmetrical clamping; P6KE200A is unidirectional and features a cathode band. Substituting them risks incorrect polarity connection or failure to suppress negative-going transients. Always verify circuit topology and consult the P6KE200CA datasheet before redesigning - the P6KE200CA must be used only where bidirectional protection is explicitly required.
