Product details
Overview
P6KE220C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 220V nominal standoff voltage, 344V maximum clamping voltage at 1.8A peak pulse current, 600W peak pulse power rating (10/1000μs), and DO-204AC (DO-15) axial package - deployed in automotive lighting control modules to safeguard microcontroller I/O against load dump and EFT events.
For engineers reviewing the P6KE220C datasheet, P6KE220C pinout, P6KE220C application, or P6KE220C equivalent, key selection criteria include its bidirectional configuration, 175°C junction temperature rating, low dynamic impedance, sub-5ns response time, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE220C operates as a silicon avalanche diode with symmetrical breakdown characteristics in both polarities, enabling robust protection of AC-coupled or floating interfaces without polarity dependency. Its 220V nominal standoff voltage (VWM = 175V min) and 242V maximum breakdown voltage (VBR) define its trigger threshold under transient stress.
It delivers 600W surge capability per the standardized 10/1000μs double-exponential waveform, with clamping performance validated at IPP = 1.8A yielding VC = 344V - ensuring downstream circuitry remains below safe operating limits during ISO 7637-2 Pulse 1/2/5a events. Thermal derating follows a linear curve above 25°C ambient, maintaining TJ ≤ 175°C under sustained surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 175 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 220V-rated systems. |
| VBR (min/max) | 198 / 242 V - Breakdown occurs within this range at 1mA test current; ensures predictable turn-on across process variation. |
| VC @ IPP | 344 V @ 1.8 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on protected ICs. |
| PPK | 600 W - Peak pulse power handling per standard waveform; validates compliance with IEC 61000-4-5 Level 4 immunity. |
| TJ max | 175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| Response time | <5 ns - Time from 0V to VBR under bidirectional surge; critical for protecting fast logic and communication interfaces. |
| Package | DO-204AC (DO-15) - Axial-leaded through-hole package with UL 94V-0 molding compound and tin-plated leads. |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional variants; P6KE220C is bidirectional and has no polarity marking - both terminals are functionally identical. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Surge current path | Both terminals conduct identically during positive or negative transients; no PCB orientation requirement. |

|---|---|
Use Scenario: Protecting LED driver outputs and CAN transceiver power rails from load dump and battery reversal transients in headlamp modules. IC Role / Device Role: Primary overvoltage clamp placed between 24V supply rail and ground, shunting surge energy away from downstream regulators and microcontrollers. Use Value: Withstands 600W surges while clamping to 344V, preventing latch-up or permanent damage to 36V-rated DC-DC converters and LIN bus transceivers. |

IC Role / Device Role: Bidirectional TVS placed across input terminals to absorb ±1kV EFT bursts per IEC 61000-4-4. Use Value: Sub-5ns response ensures clamping initiates before transient propagates into op-amp front-end stages, preserving measurement accuracy and ADC integrity. |
| Power Supply Input Stage | ESD-Prone Communication Interfaces |
Use Scenario: Front-end protection of 220V-rated AC/DC adapter inputs against lightning-induced surges and switching transients. IC Role / Device Role: Secondary-level TVS after MOV-based primary protection, providing precise clamping and fast recovery for rectifier and controller ICs. Use Value: 175°C junction rating allows reliable operation adjacent to heat-generating transformers and MOSFETs without thermal derating penalties. |

IC Role / Device Role: Bidirectional clamp across differential pair (A/B lines) to suppress ±15kV contact discharge per IEC 61000-4-2. Use Value: Symmetrical VBR (198–242V) ensures balanced clamping on both lines, eliminating common-mode offset and data corruption during ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ220CA | Same DO-214AC (SMA) package; lower 400W PPK rating; 356V VC @ 1.7A; slightly higher leakage at VWM. | Preferred for space-constrained SMT designs where board area is limited; less suitable for high-reliability automotive under-hood use. | Select when footprint reduction outweighs peak power margin and AEC-Q101 requirement. |
| ON Semiconductor 1.5KE220CA | Same DO-201AD package; 1500W PPK; 350V VC @ 4.3A; larger physical size; higher thermal mass. | Better suited for industrial motor drives with repetitive surge exposure; not AEC-Q101 qualified. | Choose for higher surge endurance in non-automotive settings where PCB real estate permits larger axial package. |
Compared with P6KE220C, SMAJ220CA trades off peak power and automotive qualification for surface-mount compatibility, while 1.5KE220CA offers greater surge capacity but lacks AEC-Q101 validation and requires more board space - making P6KE220C optimal for cost-sensitive, AEC-compliant automotive and industrial through-hole designs.

FAQ
What is the clamping voltage of P6KE220C and how is it measured?
The P6KE220C has a maximum clamping voltage (VC) of 344 V at 1.8 A peak pulse current (IPP), measured using the standardized 10/1000 μs double-exponential surge waveform per IEC 61000-4-5. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events, and is confirmed in the official Taiwan Semiconductor datasheet revision P2203.
Is P6KE220C unidirectional or bidirectional, and how does that affect PCB layout?
P6KE220C is a bidirectional TVS diode, meaning it provides symmetrical surge suppression for both positive and negative transients without polarity sensitivity. Unlike unidirectional variants (e.g., P6KE220A), it has no cathode band marking and can be mounted in either orientation - eliminating orientation checks during assembly and simplifying layout for differential or floating signal paths.
Does P6KE220C meet AEC-Q101 requirements for automotive use?
Yes, P6KE220C is AEC-Q101 qualified, as explicitly stated in the Taiwan Semiconductor P6KE series documentation (Version P2203). This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge endurance - validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum junction temperature rating for P6KE220C and why does it matter?
The P6KE220C has a maximum junction temperature (TJ) rating of 175°C, which enables reliable operation in high-ambient environments such as engine compartments or enclosed industrial enclosures. This rating directly impacts long-term reliability under repeated surge events and thermal cycling, and is critical for sustaining clamping performance without parametric drift or premature failure.
How does the DO-204AC (DO-15) package of P6KE220C compare to SMT alternatives like SMAJ220CA?
The DO-204AC (DO-15) package of P6KE220C offers higher thermal mass and proven through-hole mechanical robustness versus SMT packages like SMAJ220CA's DO-214AC. While SMAJ220CA saves board space, P6KE220C provides superior surge energy dissipation in constrained airflow environments and easier manual rework - making it preferred for high-reliability automotive and industrial through-hole assemblies.
