Product details
Overview
P6KE220A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 185V reverse standoff voltage (VRWM), 209–231V breakdown range (VBR), 328V maximum clamping voltage (VC) at 1.83A peak pulse current, and DO-15 package construction with glass-passivated die for robust surge immunity in industrial power supplies.
For engineers reviewing the P6KE220A-T datasheet, P6KE220A-T pinout, P6KE220A-T application, or P6KE220A-T equivalent, this part serves as a discrete, leaded TVS solution for high-energy ESD and lightning-induced transients where precise clamping voltage, fast response (<1 ns), and 600W non-repetitive pulse handling are required.
Technical Context
The P6KE220A-T operates as a unidirectional avalanche diode that remains high-impedance below VRWM (185V) and rapidly transitions to low-impedance conduction above VBR (min 209V) to clamp transient energy. Its 328V VC at IPP = 1.83A ensures predictable voltage limiting during 10/1000µs waveform surges.
Thermal design relies on its DO-15 package's RθJA = 75°C/W and PD = 5.0W at TL = +75°C, requiring adequate PCB copper area for heat dissipation. The device is rated for -55°C to +175°C operating temperature and complies with RoHS and J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (10/1000µs waveform; defines maximum single-event surge energy it can absorb without failure) |
| Reverse Standoff Voltage | 185V (maximum continuous DC or RMS voltage the device blocks before entering breakdown) |
| Breakdown Voltage Range | 209–231V (tested at 1.0mA; confirms reliable avalanche initiation within specified tolerance) |
| Max Clamping Voltage | 328V at 1.83A IPP (voltage seen across protected circuit during worst-case surge; sets system overvoltage margin) |
| Package | DO-15 (axial-leaded, molded plastic; UL 94V-0 rated; requires manual or wave soldering with 9.5mm lead length for thermal derating) |
| Operating Temperature | -55°C to +175°C (enables use in under-hood automotive, industrial motor drives, and outdoor power equipment) |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, cathode indicated by band marking. Leads are tin-plated, solderable per MIL-STD-202 Method 208. Weight ≈ 0.4 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; tied to ground or low-side reference in unidirectional TVS configuration | Connected to circuit ground when protecting positive rail; determines polarity of clamping action |
| Cathode | Current exit point during forward conduction; marked with band; connected to protected line | Placed on the line to be protected (e.g., +24V rail); conducts surge current to ground when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Power | Enables protection against IEC 61000-4-5 Level 4 (4kV/2Ω) surges on 24–48V industrial buses without cascading failure |
| Glass-Passivated Die Construction | Improves long-term reliability and leakage stability under humidity and thermal cycling vs. epoxy-passivated alternatives |
| Fast Response Time (<1 ns) | Clamps transients before downstream ICs (e.g., microcontrollers, RS-485 transceivers) experience damaging overvoltage |
| RoHS-Compliant Lead Finish | Supports lead-free reflow and wave soldering processes while meeting environmental compliance requirements for global markets |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input terminal and bulk capacitor, shunting surge energy to chassis ground. Use Value: Limits transient voltage to ≤328V, preventing damage to upstream rectifier bridge and downstream DC-DC controllers rated for 400V max input. |
Use Scenario: 12V battery-fed power rail in BCM controlling door locks, lighting, and window motors. IC Role / Device Role / Timing Role: Unidirectional TVS mounted directly at connector entry point to suppress ISO 7637-2 Pulse 5a (load dump up to 60V) and ESD events. Use Value: Maintains system uptime by preventing latch-up or gate oxide rupture in MCU and CAN transceivers during vehicle cranking and alternator regulation faults. |
| Telecom Remote Radio Unit (RRU) DC Feeder Line | Renewable Energy Inverter DC Link Protection |
Use Scenario: Outdoor macro base station RRU powered via 48V PoE-like feeder cable spanning >100m, subject to induced lightning surges. IC Role / Device Role / Timing Role: First-stage TVS on DC input before DC-DC conversion and RF front-end biasing circuits. Use Value: Absorbs 600W pulses without degradation, preserving signal integrity and avoiding false resets in FPGA-based digital predistortion engines. |
Use Scenario: 300–600V DC link in solar string inverters exposed to grid-switching transients and nearby lightning strikes. IC Role / Device Role / Timing Role: Secondary clamping device parallel to bulk electrolytic capacitors to limit voltage overshoot during rapid IGBT turn-off. Use Value: Reduces stress on 650V IGBTs and film capacitors by capping transient spikes to 328V, extending component lifetime and reducing warranty claims. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A-T3G | DO-214AA (SMB) package; lower RθJA (50°C/W); same VRWM (185V), VC = 328V at 1.83A | Better thermal performance in space-constrained PCB layouts; requires SMT assembly instead of through-hole | Select when automated assembly, higher power density, or improved thermal management is prioritized over legacy through-hole compatibility |
| 1N6287 | Same DO-15 package; VRWM = 185V but VC = 344V at 1.75A; 500W rating (vs. 600W) | Lower surge handling margin; less effective for IEC 61000-4-5 Level 4 compliance | Acceptable only for cost-sensitive, lower-risk applications where 100W lower pulse power is acceptable |
Compared with SMBJ220A-T3G and 1N6287, P6KE220A-T offers optimal balance of legacy through-hole manufacturability, 600W surge capacity, and proven field reliability in industrial environments - making it preferred for retrofit designs and high-surge-exposure deployments where DO-15 mechanical robustness matters.

FAQ
Is P6KE220A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE220A-T and the entire P6KE6V8(C)A–P6KE400(C)A family as of August 2024 (DS21502 Rev. 20-4). Aetrix Electronics maintains limited legacy stock for ongoing production support and offers validated alternatives including SMBJ220A-T3G for SMT migration and 1N6287 for cost-sensitive drop-in replacement where 500W rating suffices.
What is the difference between P6KE220A-T and P6KE220CA-T?
P6KE220A-T is unidirectional (cathode-banded), conducting only in reverse breakdown to clamp positive transients on a positive rail referenced to ground. P6KE220CA-T is bidirectional - symmetrical breakdown in both polarities - used for AC line protection or differential signal lines like RS-485. Their VRWM, VBR, and VC values differ slightly due to internal structure; bidirectional versions exhibit higher leakage below 10V VRWM.
Can P6KE220A-T be used in place of a Zener diode for voltage regulation?
No - P6KE220A-T is not designed for continuous voltage regulation. It is rated for non-repetitive 1ms pulses only (PPK = 600W), with steady-state power dissipation limited to 5.0W at TL = +75°C. Its VBR tolerance (±5%) and lack of tight regulation curve make it unsuitable for precision biasing or linear regulation; dedicated Zener diodes (e.g., 1N4744A) must be used for that function.
What is the recommended PCB layout for optimal thermal performance?
Mount P6KE220A-T with 9.5mm lead length on 40mm² copper land area per lead to achieve the rated 5.0W steady-state dissipation. Avoid narrow traces; use thermal reliefs only if necessary for soldering. For surge-only applications, minimize trace inductance between TVS and protected node - keep leads short and ground path low-inductance using multiple vias to inner ground planes.
