Product details
Overview
P6KE30C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust ESD and surge protection in power rails and signal lines. It features a 30V nominal standoff voltage, 43.5V maximum clamping voltage at 14A peak surge current, 600W peak pulse power rating (10/1000μs), and DO-204AC (DO-15) axial package - deployed in automotive lighting control modules to safeguard microcontroller I/O against load-dump transients.
For engineers reviewing the P6KE30C datasheet, P6KE30C pinout, P6KE30C application, or P6KE30C equivalent, key selection criteria include bidirectional clamping capability, low dynamic impedance (<1Ω typical), sub-5ns response time, and AEC-Q101 qualification for automotive-grade reliability under repetitive fast-transient stress.
Technical Context
The P6KE30C operates as a silicon avalanche diode with symmetrical breakdown behavior in both polarities, enabling single-device protection of AC-coupled or floating signal paths. Its 30V nominal breakdown voltage (VBR min 27.0V, max 33.0V at 1mA test current) ensures precise voltage thresholding without forward conduction during normal operation.
It delivers 600W non-repetitive surge dissipation per 10/1000μs waveform while maintaining TJ ≤175°C, supported by thermal derating above 25°C ambient and UL 94V-0 mold compound. The device exhibits <1μA reverse leakage at 24.3V standoff and 0.097%/°C VBR temperature coefficient - critical for stable clamping across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 24.3 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping onset |
| VBR (Breakdown) | 27.0–33.0 V @ 1 mA - Symmetrical avalanche threshold in both directions; ensures predictable turn-on during overvoltage events |
| VC @ IPP | 43.5 V @ 14 A - Clamped voltage during 10/1000μs surge; limits downstream IC stress to safe levels |
| PPK | 600 W - Peak pulse power handling capacity; meets IEC 61000-4-5 Level 4 surge immunity requirements |
| IR @ VWM | <1 μA - Ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| Response Time | <5 ns - Enables suppression of fast EFT bursts (IEC 61000-4-4) before sensitive logic is damaged |
| TJ Max | +175 °C - Supports under-hood automotive deployment with full thermal derating compliance |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, bi-directional configuration with cathode band omitted (symmetrical terminals). Case meets UL 94V-0; leads are pure tin-plated and J-STD-002 solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | No polarity marking required; either terminal serves as input/output for transient energy diversion |
| Lead 1 / Lead 2 | Current path to PCB ground plane | Leads conduct surge current directly to chassis or system ground; minimal trace inductance essential for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded sensor outputs without polarity concerns |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics per stress-test requirements (HTOL, TC, HTRB) |
| Low dynamic impedance | Typical Zdynamic < 1 Ω ensures minimal voltage overshoot during high-di/dt surges, preserving timing margins in digital interfaces |
| UL 94V-0 molding | Flame-retardant encapsulation prevents fire propagation in enclosed automotive or industrial enclosures during catastrophic failure |
| Halogen-free construction | Complies with IEC 61249-2-21; eliminates corrosive halogen emissions during reflow or end-of-life incineration |
Applications
| Automotive Lighting Control | Industrial Sensor Interface |
|---|---|

Use Scenario: PLC or RF (NB-IoT) interface in utility meter subjected to lightning-induced surges on communication lines. IC Role / Device Role / Timing Role: Series-connected TVS on RS-485 bus lines (MAX13487E), clamping common-mode transients to ground. Use Value: Withstands 10/1000μs surges up to 14A while maintaining <2% gain error in metrology ADC due to low leakage. |
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 SMAJ30CA | Same DO-214AC (SMA) package; 30V VBR range (27.0–33.0V), 43.5V VC @ 13.7A, 600W rating | Surface-mount vs. P6KE30C's through-hole DO-15; requires PCB redesign but enables higher-density layouts | Select SMAJ30CA for automated SMT assembly; retain P6KE30C for manual repair, high-vibration environments, or legacy through-hole designs |
| ON Semiconductor 1.5KE30CA | Higher 1500W rating, larger DO-201AE (DO-27) package; same 30V VBR/43.5V VC specs but 38.2A IPP | Over-specified for 600W use cases; adds mechanical bulk and cost where P6KE30C's footprint and rating are optimal | Choose 1.5KE30CA only when system-level surge testing exceeds IEC 61000-4-5 Level 4; otherwise P6KE30C offers better cost/performance fit |
Compared with SMAJ30CA and 1.5KE30CA, the P6KE30C provides optimal balance of AEC-Q101 qualification, DO-15 mechanical robustness, and precise 600W surge handling - making it preferred for cost-sensitive, vibration-prone automotive and industrial through-hole deployments where exact rating match matters.

FAQ
What is the polarity configuration of P6KE30C?
The P6KE30C is a bidirectional TVS diode with symmetrical terminals - no anode/cathode distinction. It clamps overvoltage transients equally in both directions, making it ideal for AC-coupled circuits, differential data lines, or ungrounded power domains where polarity cannot be guaranteed. This eliminates orientation errors during manual assembly and simplifies schematic symbol usage.
Does P6KE30C meet automotive qualification standards?
Yes, the P6KE30C is AEC-Q101 qualified (as indicated by the "C" suffix in its ordering code), having passed stress tests including high-temperature operating life, temperature cycling, and highly accelerated stress testing. This certification validates its suitability for under-hood and cabin electronics where reliability across -40°C to +125°C ambient and extended service life are mandatory.
What is the maximum clamping voltage of P6KE30C under surge conditions?
The P6KE30C has a maximum clamping voltage (VC) of 43.5 V at 14 A peak pulse current (IPP), measured using the standard 10/1000 μs double-exponential surge waveform. This value represents the highest voltage that will appear across the device during worst-case surge events, directly defining the protection level afforded to downstream components.
How does P6KE30C differ from the P6KE30A variant?
The P6KE30C is bidirectional, while P6KE30A is unidirectional. Their electrical parameters (VBR, VC, PPK) are identical, but P6KE30A includes a cathode band marking and conducts forward current during positive surges only. Use P6KE30C for AC or floating nodes; choose P6KE30A when protecting DC rails with defined polarity and needing lower forward voltage drop in one direction.
Can P6KE30C be used in surface-mount designs?
No - the P6KE30C uses the DO-204AC (DO-15) axial through-hole package and is not compatible with SMT processes. For surface-mount equivalents, consider SMAJ30CA (DO-214AC) or SMCJ30CA (DO-214AB), which share identical electrical specs but require PCB land pattern changes and reflow profile validation.
