Product details
Overview
P6KE220CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 220V nominal breakdown voltage (VBR min/max = 198–242V), 175V stand-off voltage (VWM), clamps to ≤344V at 1.8A peak surge current, and uses DO-204AC (DO-15) package with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE220CH datasheet, P6KE220CH pinout, P6KE220CH application, or P6KE220CH equivalent, key selection criteria include its 175°C maximum junction temperature, <1μA reverse leakage at VWM, 10/1000μs waveform surge rating, and polarity-marked cathode band for correct PCB orientation in overvoltage protection circuits.
Technical Context
The P6KE220CH operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 198–242V breakdown range at 1mA test current. Its low dynamic impedance ensures rapid clamping response (<1.0ps rise time from 0V to VBR), limiting transient energy delivered to downstream circuitry during ESD or lightning-induced surges.
Designed for single-die configuration in DO-204AC package, it supports steady-state power dissipation of 5W at 75°C ambient with 9.5mm lead length, and handles 100A non-repetitive forward surge (8.3ms half-sine) - critical for inductive load switching protection in automotive and industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 175 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 198 / 242 V - Breakdown occurs within this range at 1 mA, defining reliable turn-on threshold |
| VC @ IPP | 344 V at 1.8 A - Clamped voltage during 10/1000μs surge, limiting stress on protected ICs |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform, enabling robust surge immunity |
| IR @ VWM | <1 μA - Negligible leakage current ensures minimal standby power loss and signal integrity |
| TJ max | +175 °C - High junction temperature rating supports under-hood automotive deployment |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package with tin-plated leads, UL 94V-0 rated molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to system ground or low-side reference; completes clamping loop during transient events |
| Cathode | Reverse-biased terminal / Protection node | Connected to protected line (e.g., 24V rail); conducts avalanche current when voltage exceeds VBR |
Key Features

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 | Surface-mount SMB package (vs. axial DO-15); same 220V nominal, but lower 600W rating applies to 10/1000μs with different thermal derating curve | Preferred for space-constrained PCBs; requires rework of layout and thermal pad design | Select SMBJ220A when automated SMT assembly and board density outweigh through-hole mechanical robustness needs. |
| 1.5KE220A | Same DO-204AC package and 220V rating, but 1500W peak power (10/1000μs); higher clamping voltage (350V) and larger physical size | Better suited for high-energy utility meter or solar inverter protection where 600W is insufficient | Choose 1.5KE220A only if system-level surge testing exceeds IEC 61000-4-5 Level 4 and layout allows larger footprint. |
Compared with SMBJ220A and 1.5KE220A, the P6KE220CH offers optimal balance of AEC-Q101 qualification, axial-leaded mechanical stability, and precise 344V clamping-making it ideal for automotive and industrial designs requiring proven reliability without over-engineering surge margin.

FAQ
What does the 'H' suffix in P6KE220CH signify?
The 'H' suffix in P6KE220CH indicates AEC-Q101 qualification, confirming that the device has passed rigorous stress tests-including temperature cycling, humidity bias, and high-temperature operating life-for use in automotive electronic systems. This distinguishes it from standard P6KE220C variants and validates its suitability for under-hood and chassis-mounted applications where reliability is mission-critical. The P6KE220CH maintains identical electrical specs to non-H versions but adds full automotive-grade process and traceability controls.
Can P6KE220CH be used in bidirectional configurations?
No, P6KE220CH is a unidirectional TVS diode and must not be used in bidirectional applications. Its cathode band marking and internal structure are optimized for reverse-biased clamping only. For bidirectional protection at 220V, the correct part is P6KE220CA (with 'CA' suffix), which provides symmetrical breakdown in both polarities. Using P6KE220CH in AC or bipolar signal paths risks failure due to forward conduction during negative transients.
What is the maximum allowable mounting temperature for P6KE220CH during reflow or hand soldering?
P6KE220CH uses tin-plated leads compliant with J-STD-002 and is rated for wave and hand soldering only-not reflow. The maximum peak solder temperature is 260°C for 10 seconds, with preheat up to 150°C. Reflow profiles exceeding 220°C will degrade the epoxy molding compound and compromise UL 94V-0 flammability rating. Always follow DO-204AC lead-forming and thermal management guidelines to avoid junction overheating during assembly.
How does P6KE220CH's clamping voltage compare to competing 220V TVS diodes?
P6KE220CH clamps to a maximum of 344V at 1.8A (10/1000μs), which is 6% lower than the 365V typical clamping of 1.5KE220A and matches the 344V spec of SMAJ220A. This tighter clamping margin directly improves system-level surge immunity by reducing voltage stress on downstream components like MOSFETs and gate drivers. The P6KE220CH achieves this via optimized silicon geometry and low dynamic impedance, confirmed in TSC's published V-I curves.
Is P6KE220CH RoHS and halogen-free compliant?
Yes, P6KE220CH is fully RoHS compliant and halogen-free per IEC 61249-2-21. The epoxy molding compound contains no brominated flame retardants or chlorine-based additives, and all metallic elements meet EU Directive 2011/65/EU restrictions. Certificate of Compliance and material declarations are available upon request from Aetrix Electronics for full supply chain traceability and environmental compliance reporting.
