Product details
Overview
P6KE27C 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 27V nominal breakdown voltage (VBR min/max: 24.3V–29.7V), 600W peak pulse power rating at 10/1000μs, clamping voltage of 39.1V at 16A peak surge current, and operates across –55°C to +175°C junction temperature range. It is used in automotive lighting control modules to protect CAN transceiver inputs from load-dump and EFT-induced transients.
For engineers reviewing the P6KE27C datasheet, P6KE27C pinout, P6KE27C application, or P6KE27C equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, low clamping ratio (VC/VBR ≈ 1.52), sub-1μA leakage at 21.8V stand-off, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P6KE27C implements a silicon avalanche diode structure optimized for fast transient response (<5.0ns for bidirectional operation) and low dynamic impedance. Its unidirectional/bidirectional symmetry enables dual-polarity clamping without external polarity management, supporting both line-to-line and line-to-ground surge suppression.
It complies with ANSI/IEEE C62.35 for surge testing and meets UL 94V-0 flammability requirements in its DO-204AC molded package. The device sustains 100A non-repetitive forward surge (IFSM) and maintains stable VBR temperature coefficient of 0.096%/°C - critical for thermal stability in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 24.3V–29.7V at IT = 1mA: defines reliable avalanche initiation window for predictable clamping onset |
| VWM | 21.8V: maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPP | 39.1V at 16A (10/1000μs): actual voltage seen by protected IC during worst-case surge - determines system overvoltage tolerance |
| PPK | 600W: peak surge energy absorption capability - supports IEC 61000-4-5 Level 4 (4kV) compliance with appropriate PCB layout |
| ID @ VWM | <1μA: ultra-low leakage ensures minimal standby power loss and avoids false triggering in high-impedance circuits |
| TJ max | +175°C: extended junction temperature rating enables placement near heat sources (e.g., power MOSFETs, LED drivers) |
| Package | DO-204AC (DO-15): industry-standard axial leaded package with 0.400g mass and tin-plated leads per J-STD-002 |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, bi-directional symmetric construction. Cathode band marking not applicable - terminals are electrically identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as input/output; no polarity dependency - simplifies PCB routing and eliminates orientation errors |
| Lead 1 / Lead 2 | Current path for surge conduction | Both leads conduct equally during positive or negative transients; requires equal copper pour area on both sides for thermal balance |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN bus) without external diode pairing |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics - supports PPAP documentation requirements |
| Low clamping ratio (VC/VBR ≈ 1.52) | Minimizes overvoltage stress on downstream ICs compared to alternatives with ratios >1.6 - extends lifetime of protected transceivers |
| Fast response time | <5.0ns turn-on for bidirectional mode ensures suppression before transient energy couples into sensitive analog front-ends |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive - suitable for export-controlled and green manufacturing programs |
Applications
| Automotive Lighting Control | Industrial PLC I/O Protection |

| USB-C Power Delivery Port | Smart Meter Communication Interface |
|
Use Scenario: Protecting CC1/CC2 configuration channel pins in USB-C receptacles against hot-plug induced transients and ESD. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100pF at VR=0) placed adjacent to connector, grounded via shortest possible trace. Use Value: Clamps ±15kV contact ESD (IEC 61000-4-2) without distorting 300kHz PD communication waveform due to fast response and symmetric clamping. |
Use Scenario: Shielding HPLC (high-speed power line communication) modem ICs in electricity meters from grid-sourced surges and switching noise. IC Role / Device Role / Timing Role: Line-to-line TVS on differential PLC pair (L1/L2), rated for repeated 6kV surges per IEC 61000-4-5. Use Value: Maintains signal fidelity up to 500kHz by limiting clamping overshoot to <39.1V - avoids data corruption during burst-mode transmission. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | Lower PPK (600W same), but tighter VBR tolerance (22.8–25.2V), lower VC (38.9V @ 15.4A), DO-214AA package | Surface-mount only; requires reflow-compatible layout and lacks axial lead mechanical robustness for high-vibration environments | Select when board space is constrained and vibration exposure is low; verify thermal pad design for 175°C operation |
| 1.5KE27CA | Same DO-204AC package and VBR range, but higher PPK (1500W), larger junction capacitance, and slower response (~10ns) | Over-specified for most 600W-use cases; introduces unnecessary cost and potential signal distortion in high-speed lines | Choose only when legacy 1.5KE footprint reuse is mandatory and surge threat level exceeds 600W - otherwise P6KE27C offers optimal balance |
Compared with SMBJ24CA and 1.5KE27CA, the P6KE27C delivers best-in-class clamping speed and AEC-Q101 validation in an axial package - making it the preferred choice for automotive and industrial applications where mechanical reliability and sub-5ns response are design-critical.

FAQ
What is the polarity configuration of P6KE27C?
The P6KE27C is a bidirectional TVS diode with symmetrical terminals - neither lead is designated anode or cathode. This allows flexible placement across any two points needing transient suppression, such as line-to-line or line-to-ground paths, without regard to orientation. The P6KE27C achieves this through internal back-to-back avalanche junctions, enabling identical clamping behavior for both positive and negative transients.
Does P6KE27C meet AEC-Q101 qualification?
Yes, the P6KE27C 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 - validating its suitability for automotive under-hood and cabin applications. The "C" suffix in P6KE27C denotes bidirectional configuration and AEC-Q101 compliance per ordering code conventions.
What is the maximum clamping voltage of P6KE27C under surge conditions?
The P6KE27C has a maximum clamping voltage (VC) of 39.1V at 16A peak pulse current (IPP), measured using the standard 10/1000μs double-exponential waveform. This value represents the highest voltage that will appear across the protected circuit during a full-rated 600W surge event - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Can P6KE27C be used in place of unidirectional TVS diodes?
No - the P6KE27C is strictly bidirectional and must not replace unidirectional TVS diodes (e.g., P6KE27A) in DC-biased circuits where reverse polarity blocking is required. In a unidirectional application like 24V rail-to-ground protection, using P6KE27C would allow reverse conduction during normal operation. Always match device polarity to circuit topology: use P6KE27A for DC rail clamping, P6KE27C only for AC, floating, or differential line protection.
What is the junction temperature rating of P6KE27C?
The P6KE27C has a maximum junction temperature (TJ) rating of +175°C and a minimum of –55°C, enabling operation in harsh thermal environments such as automotive engine compartments or industrial motor drives. This wide range supports reliable performance without derating up to 125°C ambient when mounted on recommended 5×5 mm copper pads - a key advantage over many consumer-grade TVS diodes limited to +150°C.
