Product details
Overview
P6KE220CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 185V reverse standoff voltage (VRWM), 209–231V breakdown range (VBR), 328V clamping voltage (VC) at 1.83A peak pulse current, and DO-15 package with glass-passivated junction-used in industrial power supply input stages and automotive body control modules.
For engineers reviewing the P6KE220CA-T datasheet, P6KE220CA-T pinout, P6KE220CA-T application, or P6KE220CA-T equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirements, 1.0ms pulse waveform compliance, thermal derating above +25°C ambient, and RoHS-compliant lead-free plating for reflow soldering.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by transient overvoltage events exceeding its breakdown threshold. Its bidirectional construction enables symmetrical clamping of both positive and negative transients without external polarity orientation, making it suitable for AC-coupled or floating signal paths.
The device uses a glass-passivated silicon junction to achieve fast response time (<1.0ns), low leakage (<5.0µA at VRWM), and stable VBR tolerance (±5%). Thermal resistance values (RθJA = 75°C/W, RθJL = 15°C/W) define its steady-state power handling (5.0W at TL = +75°C) and pulse survivability under IEC 61000-4-5 surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive 10/1000µs waveform-defines maximum transient energy absorption capability |
| Reverse Standoff Voltage | 185V (VRWM)-maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage Range | 209–231V (VBR @ 1.0mA)-guaranteed conduction onset window under standardized test current |
| Clamping Voltage | 328V (VC @ 1.83A IPP)-voltage seen by protected circuit during full-rated surge event |
| Package | DO-15 molded plastic case-industry-standard axial-leaded through-hole package with UL 94V-0 flammability rating |
| Operating Temperature | −55°C to +175°C-supports under-hood automotive and high-temperature industrial environments |
| RoHS Compliance | Lead-free finish per EU Directive 2011/65/EU-meets global environmental manufacturing requirements |
Pinout & Package
DO-15 package: axial-leaded, cylindrical epoxy-molded body with cathode band marking on unidirectional variants; bidirectional version (P6KE220CA-T) carries no polarity marking. Leads are tin-plated, solderable per MIL-STD-202 Method 208, with 0.4g typical weight and 9.5mm lead length for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during negative transient | One end of symmetrical PN junction-no fixed polarity; conducts when voltage across terminals exceeds |VBR| in either direction |
| Cathode | Current entry terminal during positive transient | Other end of symmetrical PN junction-identical electrical behavior to anode; bidirectional operation requires no orientation during PCB placement |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables robust protection against IEC 61000-4-5 Level 4 (4kV/2Ω) surges on 24V/48V industrial buses |
| Glass-passivated die construction | Improves long-term reliability and moisture resistance versus epoxy-passivated alternatives in humid environments |
| Bidirectional configuration | Eliminates need for polarity-aware layout-simplifies design for AC lines, differential data, or floating grounds |
| Fast response time (<1.0ns) | Clamps transients before downstream ICs experience damaging overvoltage-critical for protecting sensitive microcontrollers |
| Low clamping ratio (VC/VBR ≈ 1.57) | Minimizes voltage overshoot during clamping-reduces stress on protected MOSFETs, gate drivers, and analog front-ends |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |
|---|---|
Use Scenario: 24V DC input protection against load dump and inductive switching spikes in programmable logic controller field terminals. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter and isolation barrier.

| Telecom Power Feeds | Renewable Energy Inverter DC Links |
Use Scenario: Surge suppression on −48V telecom power distribution boards exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Secondary-level protector after gas discharge tube (GDT), absorbing residual energy after GDT fires.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA-T | Same VRWM (185V), lower PPK (600W → 600W), but SMB package (surface-mount); RθJA = 40°C/W vs. 75°C/W | Requires PCB real estate optimization; better thermal performance in compact layouts but less mechanical robustness than axial DO-15 | Select for space-constrained designs where automated SMT assembly is preferred and thermal management via copper pour is feasible |
| 1.5KE220CA-T | Higher PPK (1500W), same VRWM and bidirectional structure, but larger DO-201AD package and higher clamping (350V vs. 328V) | Used where higher surge immunity (IEC 61000-4-5 Level 5) is required, accepting larger board footprint and higher clamping voltage | Select when system-level surge testing mandates >600W pulse handling and board layout allows larger axial package |
Compared with SMBJ220CA-T and 1.5KE220CA-T, P6KE220CA-T offers optimal balance of proven DO-15 mechanical reliability, moderate clamping voltage, and compatibility with legacy through-hole manufacturing-making it preferred for cost-sensitive industrial controls where manual rework or field repair is anticipated.

FAQ
Is P6KE220CA-T still in active production?
No-Diodes Incorporated has officially discontinued the P6KE220CA-T as of August 2024 (DS21502 Rev. 20-4). Aetrix Electronics maintains limited legacy stock sourced directly from Diodes' final production lots, with full traceability and documentation. No new manufacturing runs are planned.
What is the maximum allowable mounting temperature for P6KE220CA-T during reflow soldering?
The DO-15 package is not rated for reflow soldering. P6KE220CA-T is intended for wave soldering or hand-soldering only. Peak solder temperature must not exceed 260°C for ≤10 seconds, with preheat ≤150°C. Reflow exposure risks internal delamination and parameter shift due to thermal mismatch in axial-leaded construction.
Can P6KE220CA-T be used in place of a unidirectional P6KE220A-T?
No-P6KE220CA-T is bidirectional and lacks cathode marking; substituting it for unidirectional P6KE220A-T may cause unintended conduction in DC-biased circuits. The CA suffix explicitly denotes symmetrical clamping. Polarity-sensitive applications (e.g., DC power rail protection with single-polarity transients) require verification of circuit topology before substitution.
Does P6KE220CA-T meet AEC-Q200 stress testing requirements?
No-while Diodes manufactures AEC-Q200-qualified TVS devices (e.g., DZxx family), the P6KE series is not AEC-Q200 certified. It is qualified for industrial-grade operation (−55°C to +175°C), but automotive qualification requires additional vibration, temperature cycling, and humidity testing not performed on this series.
