Product details
Overview
P6KE22C from Taiwan Semiconductor 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 nominal breakdown voltage of 22 V, clamps transients to ≤31.9 V at 19 A peak surge current, and delivers sub-1 ps response time from 0 V to VBR. It is used in automotive body control modules to safeguard CAN transceivers against ISO 7637-2 pulse 1/2a-induced surges.
For engineers reviewing the P6KE22C datasheet, P6KE22C pinout, P6KE22C application, or P6KE22C equivalent, this page provides verified electrical parameters, DO-204AC package details, clamping performance under 10/1000 µs waveform, junction temperature limits up to +175 °C, and AEC-Q101 qualification status - all critical for ESD and load-dump robustness validation.
Technical Context
The P6KE22C operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its minimum breakdown threshold of 19.8 V. Its low dynamic impedance ensures stable clamping during fast transients, while its 10/1000 µs surge rating of 600 W enables reliable suppression of automotive load-dump events without thermal runaway.
Designed for surface-mount-compatible through-hole assembly, it uses a DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The cathode band marking defines polarity, and its junction capacitance remains below 100 pF at 0 V, minimizing signal distortion in protected data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 19.8 V - Ensures reliable conduction onset before downstream IC damage occurs at rated system voltage |
| VBR (max) | 24.2 V - Defines worst-case clamping initiation point across temperature and unit variation |
| VC @ IPP | 31.9 V at 19 A - Maximum clamped voltage seen by protected circuit during 10/1000 µs surge |
| VWM | 17.8 V - Maximum continuous reverse operating voltage; sets safe margin below VBR |
| IR @ VWM | <1 µA - Negligible leakage current preserves battery life in always-on automotive modules |
| TJMAX | +175 °C - Enables operation in under-hood environments without derating at full power |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package compatible with legacy wave-solder and hand-solder processes |

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 SMAJ22A | Same DO-214AC package; 400 W rating; VC = 35.5 V at 11.8 A; higher clamping voltage | Lower surge capacity limits use in high-energy load-dump scenarios; better suited for ESD-only zones | Select when board space constraints require SMD mounting and surge energy is ≤400 W |
| ON Semiconductor 1.5KE22C | Same DO-204AC package; 1500 W rating; VC = 33.2 V at 45.2 A; higher power but larger footprint | Higher surge margin supports heavy-duty truck applications; requires larger PCB pad area | Select when system-level testing demands >600 W immunity and layout allows larger axial device |
Compared with SMAJ22A, P6KE22C offers 50% higher surge power and lower clamping voltage for tighter protection margins; compared with 1.5KE22C, it reduces board area and cost while meeting standard automotive load-dump requirements.

FAQ
What is the polarity configuration of P6KE22C?
The P6KE22C is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. Its cathode band marks the terminal that connects to the protected line (e.g., 12 V rail), while the anode connects to ground. This configuration blocks normal forward current and activates solely during overvoltage events on the cathode side.
Is P6KE22C AEC-Q101 qualified?
Yes, P6KE22C is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor P6KE Series datasheet (Version P2203). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, making P6KE22C suitable for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of P6KE22C under surge conditions?
The maximum clamping voltage of P6KE22C is 31.9 V at a peak pulse current (IPP) of 19 A, measured using the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across all units and represents the highest voltage the protected circuit will experience during a full-rated 600 W transient event.
Can P6KE22C be used in bidirectional configurations?
No, P6KE22C is strictly unidirectional. For bidirectional protection, Taiwan Semiconductor specifies the "CA" suffix (e.g., P6KE22CA), which uses a dual-die configuration. Using P6KE22C in bidirectional applications risks forward conduction during positive transients and inadequate protection on the non-clamping polarity.
What is the junction temperature limit for continuous operation of P6KE22C?
The P6KE22C has a maximum junction temperature (TJMAX) of +175 °C, allowing uninterrupted operation in under-hood automotive environments. At ambient temperatures up to +125 °C, its 600 W surge capability remains fully rated when mounted per JEDEC standards (5 × 5 mm copper pads per lead).
