Product details
Overview
P6KE22CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for circuit-level ESD and surge protection in automotive, industrial, and consumer electronics. It features a nominal breakdown voltage of 22 V, clamping voltage of 33.2 V at 19.0 A peak pulse current, stand-off voltage of 18.8 V, and operates within –55°C to +175°C junction temperature range.
For engineers reviewing the P6KE22CA datasheet, P6KE22CA pinout, P6KE22CA application, or P6KE22CA equivalent, key selection criteria include bidirectional clamping performance under 10/1000 µs surge, low dynamic impedance, sub-5 ns response time, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE22CA is a single-die, DO-204AC (DO-15) packaged bidirectional TVS diode optimized for fast transient suppression across both polarities. Its electrical behavior follows ANSI/IEEE C62.35 standards, with specified breakdown voltage min/max of 20.9 V / 23.1 V at 1 mA test current and maximum clamping voltage of 33.2 V at 19.0 A IPP.
It delivers 600 W non-repetitive peak pulse power per 10/1000 µs waveform, with thermal derating above 25°C ambient and junction temperature limits up to +175°C. Reverse leakage remains below 1 µA at 18.8 V, supporting low-power system integrity during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at 1 mA - defines reliable conduction onset window for bidirectional overvoltage clamping |
| VWM | 18.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP | 33.2 V at 19.0 A - peak clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPK | 600 W - surge energy handling capacity under standardized transient waveform |
| IR @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +175°C - enables operation in under-hood automotive or high-temperature industrial environments |
| Response time | <5.0 ns - ensures effective suppression of fast EFT and ESD transients before IC damage occurs |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (marked band) | Bidirectional terminal pair | Marked cathode band indicates polarity reference; device functions identically in either direction due to symmetrical structure |
| Lead 1 / Lead 2 | Surge current path | Both leads conduct surge current equally during positive or negative transients; no dedicated anode/cathode assignment required for bidirectional use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA (Bourns) | Same 22 V nominal, 600 W rating, but SMB package (surface-mount); lower thermal resistance than DO-15 | Better suited for automated SMT assembly; requires PCB layout change from axial to SMD footprint | Select SMBJ22CA when board space is constrained and reflow compatibility is required |
| 1.5KE22CA (ON Semiconductor) | Identical DO-204AC package and 22 V rating, but rated for 1500 W peak power (10/1000 µs); higher clamping voltage (35.5 V) | Higher surge margin for harsher environments (e.g., utility metering), but less precise clamping for sensitive 24 V logic | Select 1.5KE22CA when legacy design uses same footprint but demands higher surge endurance |
Compared with P6KE22CA, SMBJ22CA offers surface-mount flexibility and improved thermal performance, while 1.5KE22CA provides greater surge headroom at the cost of higher clamping voltage-making P6KE22CA optimal for cost-sensitive, thermally stable 24 V automotive and industrial interfaces where precise clamping is critical.

FAQ
What is the clamping voltage of P6KE22CA and how is it measured?
The P6KE22CA has a maximum clamping voltage (VC) of 33.2 V at 19.0 A peak pulse current (IPP), tested under the standard 10/1000 µs double-exponential surge waveform. This value represents the highest voltage the device allows across its terminals during a defined transient event, ensuring downstream components remain within safe operating limits. The P6KE22CA achieves this clamping performance while maintaining low dynamic impedance and sub-5 ns response time.
Is P6KE22CA suitable for automotive applications?
Yes, P6KE22CA is AEC-Q101 qualified (as indicated by the "H" suffix variant P6KE22CAH), making it suitable for automotive applications including engine control units, body electronics, and infotainment systems. Its –55°C to +175°C operating temperature range, robust surge handling, and certified reliability meet stringent automotive environmental and lifetime requirements. The P6KE22CA meets all relevant stress tests including temperature cycling, humidity bias, and mechanical shock per AEC-Q101.
How does P6KE22CA differ from unidirectional P6KE22A?
P6KE22CA is bidirectional, meaning it clamps transients of either polarity symmetrically, while P6KE22A is unidirectional and only protects against reverse-polarity surges. The CA version has identical breakdown (20.9–23.1 V), clamping (33.2 V), and power (600 W) specs but supports AC-coupled or floating signal lines. P6KE22CA replaces two unidirectional devices in differential or dual-rail applications, simplifying layout and reducing BOM count compared to using P6KE22A in mirrored configuration.
What is the package type and mounting requirement for P6KE22CA?
P6KE22CA uses the DO-204AC (DO-15) axial-leaded package with 0.400 g typical weight, UL 94V-0 molded compound, and pure tin-plated leads compliant with J-STD-002 solderability. It requires through-hole mounting on PCBs with recommended 5 × 5 mm copper pads per lead for optimal thermal dissipation. The device's polarity is marked with a cathode band, though for bidirectional operation, orientation is not functionally critical-both leads serve as symmetrical surge paths in the P6KE22CA.
Does P6KE22CA meet RoHS and halogen-free requirements?
Yes, P6KE22CA is RoHS compliant and halogen-free per IEC 61249-2-21, verified by Taiwan Semiconductor's material declarations and manufacturing process controls. This ensures compatibility with lead-free reflow profiles and environmentally regulated markets including EU, China, and South Korea. The P6KE22CA contains no brominated flame retardants (BFRs), antimony trioxide, or other restricted substances above threshold limits, supporting sustainable electronics manufacturing and end-of-life recycling.
