Product details
Overview
P6KE220A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 220 V, clamps transients to ≤328 V at 1.9 A peak surge current, and maintains ≤1 μA reverse leakage at its 185 V stand-off voltage. It is used in automotive lighting control modules to protect microcontroller I/O against load-dump-induced surges.
For engineers reviewing the P6KE220A datasheet, P6KE220A pinout, P6KE220A application, or P6KE220A equivalent, key selection criteria include clamping voltage margin relative to system rail, junction temperature derating above 25°C, unidirectional polarity marking, and DO-15 package compatibility with existing PCB footprints for high-energy surge suppression.
Technical Context
The P6KE220A operates as a silicon avalanche diode with fast response (<1.0 ps from 0 V to VBR) and low dynamic impedance to limit transient overvoltages before downstream components are stressed. Its 10/1000 µs waveform surge rating of 600 W defines its energy-handling capability under standardized lightning/inductive-switching stress profiles.
It is rated for junction temperatures from –55°C to +175°C and exhibits a temperature coefficient of VBR of 0.108 %/°C - enabling predictable voltage drift across automotive under-hood thermal ranges. The device uses a single-die DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications

Applications
| Automotive Lighting Control | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN transceivers and LED driver ICs in headlamp control units exposed to battery load-dump events up to 120 V. IC Role / Device Role: Unidirectional TVS placed between 24 V supply rail and ground to clamp positive-going transients. Use Value: Limits voltage to ≤328 V during 600 W surges, preventing latch-up or gate oxide damage in 3.3 V/5 V logic interfaces downstream. | Use Scenario: Safeguarding analog input channels (e.g., 4–20 mA sensors) in programmable logic controllers subjected to field-wiring induced transients. IC Role / Device Role: Standoff protection element mounted at connector entry point to shunt surge energy before signal conditioning circuitry. Use Value: Maintains ≤1 μA leakage at 185 V, avoiding measurement error in high-impedance sensor front-ends while surviving repeated 1 kV/500 A surges. |
| DC Power Supply Rail Protection | Motor Drive Gate Driver Protection |
Use Scenario: Secondary-side overvoltage suppression on 220 V DC bus outputs of industrial AC/DC converters. IC Role / Device Role: Parallel-connected TVS absorbing residual switching spikes and line transients not filtered by bulk capacitance. Use Value: Clamps 1.9 A surge to 328 V within 1 ps, reducing stress on downstream DC-DC converter input capacitors and MOSFETs. | Use Scenario: Protecting isolated gate drivers (e.g., SiC MOSFET drivers) from Miller-induced voltage spikes during high-dV/dt switching. IC Role / Device Role: Localized TVS across driver output pins to clamp coupled transients before gate threshold violation. Use Value: Low dynamic impedance ensures rapid voltage stabilization, preventing false turn-on or gate oxide overstress during 100 ns-scale spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A | Same 220 V nominal VBR, but SMC package (surface-mount), 600 W rating, lower VC = 324 V @ 1.9 A | Requires PCB rework for SMD footprint; better thermal dissipation in compact layouts | Select SMBJ220A when board space is constrained and automated assembly is preferred over through-hole mounting. |
| 1.5KE220A | Same DO-204AC package, but 1500 W rating, higher VC = 355 V @ 4.2 A, larger case mass | Over-spec'd energy handling for most 600 W use cases; may require revised thermal layout due to higher power density | Choose 1.5KE220A only if legacy designs demand backward-compatible DO-15 footprint with headroom for future surge level increases. |
Compared with SMBJ220A and 1.5KE220A, the P6KE220A offers optimal balance of axial-leaded manufacturability, precise 600 W surge matching, and proven fit in automotive lighting and industrial control chassis where DO-15 mechanical retention and serviceability are prioritized.

FAQ
What is the maximum clamping voltage of the P6KE220A under standard surge conditions?
The P6KE220A clamps to a maximum of 328 V when subjected to its rated 1.9 A peak pulse current (IPP) under the 10/1000 µs waveform. This value is measured at TA = 25°C and defines the upper voltage limit imposed on protected circuitry during transient events. Designers must ensure this clamping voltage remains below the absolute maximum ratings of downstream components in the P6KE220A-protected path.
Is the P6KE220A suitable for bidirectional transient protection?
No, the P6KE220A is a unidirectional TVS diode, indicated by its "A" suffix and cathode band marking. It conducts only when the cathode is positive relative to the anode. For bidirectional protection, select the P6KE220CA variant - which provides symmetrical clamping in both polarities and is explicitly designated for AC-line or data-line applications requiring dual-polarity surge suppression.
Does the P6KE220A meet automotive qualification standards?
The base P6KE220A is not AEC-Q101 qualified; however, the P6KE220AH variant (with "H" suffix) is fully AEC-Q101 qualified for automotive applications. The "H" version undergoes additional stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - making it suitable for under-hood and body-control module deployments where reliability validation is mandatory.
How does the P6KE220A's leakage current affect high-impedance circuits?
The P6KE220A exhibits ≤1 μA reverse leakage current at its 185 V stand-off voltage (VWM), measured at 25°C. This ultra-low leakage ensures minimal loading on high-impedance nodes such as precision sensor inputs or voltage-monitoring dividers. At elevated temperatures (e.g., 125°C), leakage may increase to ~10 μA - still acceptable for most industrial monitoring circuits but warranting verification in battery-powered or nanoamp-level systems.
What is the thermal derating behavior of the P6KE220A above 25°C ambient?
The P6KE220A's peak pulse power rating of 600 W is specified at TA = 25°C and must be linearly derated above that temperature per the manufacturer's pulse derating curve (Fig.2). At 75°C ambient, its surge capability drops to approximately 450 W; at 125°C, it falls to ~270 W. Designers must apply this derating when placing the P6KE220A near heat sources or in sealed enclosures to avoid thermal runaway during repetitive surge events.
