Product details
Overview
P6KE220CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a nominal breakdown voltage of 220 V, clamps transients to ≤344 V at 1.8 A peak surge current, and delivers sub-nanosecond response time (<5 ns) for ESD and EFT immunity in automotive and industrial control systems.
For engineers reviewing the P6KE220CAH datasheet, P6KE220CAH pinout, P6KE220CAH application, or P6KE220CAH equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility, bidirectional clamping symmetry, and 175°C maximum junction temperature for under-hood deployment.
Technical Context
The P6KE220CAH implements a silicon avalanche diode structure optimized for unidirectional and bidirectional transient suppression. Its electrical characteristics are symmetric in both directions due to the CA suffix designation, with identical VBR min/max (198–242 V), VWM (175 V), and VC (≤344 V @ IPP = 1.8 A) specifications.
It operates within a -55°C to +175°C junction temperature range and supports 10/1000 μs waveform surge handling up to 600 W. The device meets UL 94V-0 flammability standards, JESD201 Class 2 whisker resistance, and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 198 V / 242 V - Ensures reliable conduction onset across manufacturing tolerance and temperature variation |
| VWM | 175 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPP | ≤344 V @ 1.8 A - Clamped voltage during 10/1000 μs surge defines protected circuit's peak stress level |
| PPK | 600 W - Peak pulse power rating determines survivability against lightning-induced surges |
| TJ max | +175°C - Enables placement near heat sources in automotive engine control units |
| Response time | <5 ns - Fast turn-on ensures suppression before sensitive ICs experience overvoltage damage |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400 g mass and tin-plated leads |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 rating. Cathode band marking denotes polarity for unidirectional variants; P6KE220CAH is bidirectional and lacks cathode band - terminals are functionally interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | Both terminals serve as symmetrical avalanche junction connections - no polarity dependency in circuit layout |
| Lead 1 / Lead 2 | Mechanical interface | 0.51 mm diameter tinned copper leads, solderable per J-STD-002, support manual or wave soldering |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per Rev G requirements |
| Bidirectional clamping | Identical VBR and VC performance in both directions eliminates need for polarity-aware PCB routing |
| Low dynamic impedance | Enables tight clamping window (VBR to VC spread ≤146 V) for robust protection of 200 V-class systems |
| 600 W surge rating | Withstands IEC 61000-4-5 Level 4 (4 kV line-to-line) surges when properly decoupled |
| 175°C junction rating | Supports operation in under-hood environments without derating below 125°C ambient |
Applications
| Automotive Power Rail Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting 24 V and 48 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed at power entry point before DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤344 V during 600 W surges, preventing latch-up or gate oxide rupture in downstream SiC MOSFET drivers. |
Use Scenario: Safeguarding analog input channels of programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end TVS on 0–10 V or 4–20 mA sensor interfaces subjected to EFT bursts per IEC 61000-4-4. Use Value: Sub-5 ns response ensures clamping activation before 50 ns EFT pulses propagate into precision op-amp front-ends. |
| LED Driver Surge Suppression | Telecom DC Feeder Protection |
Use Scenario: Shielding constant-current LED drivers in street lighting from induced lightning surges on long AC/DC feeders. IC Role / Device Role / Timing Role: Parallel-connected TVS across output terminals to clamp inductive kickback and grid-coupled transients. Use Value: 600 W rating sustains multiple 10/1000 μs events without degradation, extending driver MTBF in outdoor deployments. |
Use Scenario: Protecting PoE-powered equipment connected to telecom central office DC feeds prone to cross-talk and switching surges. IC Role / Device Role / Timing Role: Bidirectional shunt device on -48 V DC supply rail upstream of DC-DC isolation stage. Use Value: Symmetric clamping prevents reverse-bias overstress on isolated DC-DC controller ICs during polarity-inverted surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same 220 V nominal, 600 W rating, but SMB package (surface-mount); lower thermal mass and higher mounting density | Requires rework of PCB layout; better suited for space-constrained designs with automated assembly | Select SMBJ220CA when board area is limited and thermal management via copper pour is feasible |
| 1.5KE220CA | Same DO-15 package and 220 V rating, but 1500 W peak power; larger die, higher capacitance (~100 pF vs. ~30 pF) | Higher clamping voltage (≤370 V) and slower response; suitable only where surge energy exceeds 600 W | Choose 1.5KE220CA only if system-level testing confirms need for >600 W surge margin and layout accommodates higher VC |
Compared with SMBJ220CA and 1.5KE220CA, the P6KE220CAH offers optimal balance of AEC-Q101 compliance, DO-15 through-hole manufacturability, and precise 344 V clamping-making it ideal for cost-sensitive, thermally stable automotive and industrial power rail protection where 600 W is sufficient.

FAQ
What does the "CA" suffix indicate in P6KE220CAH?
The "CA" suffix in P6KE220CAH denotes bidirectional configuration - meaning the device provides symmetrical avalanche clamping in both forward and reverse bias directions. This eliminates polarity concerns during PCB placement and enables use in AC-coupled or floating signal paths where voltage polarity may reverse. Unlike unidirectional "A" variants, P6KE220CAH has identical VBR, VC, and leakage specs in either direction.
Is P6KE220CAH suitable for IEC 61000-4-5 surge testing?
Yes, P6KE220CAH is rated for 600 W peak pulse power with a 10/1000 μs waveform - matching the energy profile of IEC 61000-4-5 Level 4 (4 kV line-to-line) surges. When used with appropriate series impedance (e.g., 2 Ω source impedance), it clamps the protected node to ≤344 V, ensuring downstream components remain within safe operating limits during standardized surge immunity validation.
How does the AEC-Q101 qualification impact P6KE220CAH's use in automotive designs?
The AEC-Q101 qualification confirms that P6KE220CAH has passed accelerated stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - all required for automotive under-hood and chassis-mounted applications. This certification assures reliability over 15+ years of service life at 125°C ambient, making P6KE220CAH suitable for engine control units, body control modules, and ADAS power supplies.
What is the maximum steady-state power dissipation for P6KE220CAH at 75°C ambient?
P6KE220CAH has a steady-state power dissipation (PD) rating of 5 W at TA = 75°C with 9.5 mm lead lengths mounted on 5 × 5 mm copper pads. This value reflects thermal equilibrium under continuous reverse-bias leakage conditions and is distinct from its 600 W transient rating. Designers must ensure board-level thermal relief (e.g., thermal vias, copper pours) to maintain junction temperature ≤175°C during sustained operation.
Can P6KE220CAH be used in place of P6KE220A in a new design?
No - P6KE220CAH and P6KE220A are not interchangeable. P6KE220A is unidirectional with cathode marking and asymmetric behavior, while P6KE220CAH is bidirectional with no polarity marking. Substituting one for the other risks incorrect clamping during reverse-polarity transients or misalignment with existing schematic symbols. Always verify directionality and marking conventions before replacement.
