Product details
Overview
P6KE10C from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a 10V nominal breakdown voltage (VBR min/max = 9.0–11.0V), 8.1V stand-off voltage (VWM), 15.0V maximum clamping voltage at 42A peak surge current, and operates across –55°C to +175°C junction temperature range - deployed in automotive body control modules and industrial PLC I/O protection.
For engineers reviewing the P6KE10C datasheet, P6KE10C pinout, P6KE10C application, or P6KE10C equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, 10/1000μs surge rating compliance for ISO 7637-2 Pulse 1/2a, unidirectional polarity marking, DO-15 mechanical fit in legacy PCB footprints, and AEC-Q101 qualification status for automotive use.
Technical Context
The P6KE10C employs a planar junction silicon avalanche structure optimized for fast transient response (<1.0ps rise time from 0V to VBR) and low dynamic impedance. Its unidirectional configuration provides asymmetric conduction: low forward voltage drop under fault conditions and high reverse blocking up to 8.1V during normal operation.
Thermal design relies on its DO-204AC (DO-15) package with pure tin-plated leads and UL 94V-0 molding compound, enabling 5W steady-state dissipation at 75°C ambient when mounted on 5×5 mm copper pads - critical for sustained EFT burst immunity in industrial controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VBR | 10 V - defines rated clamping threshold; actual breakdown occurs between 9.0 V and 11.0 V at 1 mA test current |
| Stand-off Voltage VWM | 8.1 V - maximum continuous reverse voltage before leakage exceeds 10 μA; sets safe operating margin below VBR |
| Max Clamping Voltage VC | 15.0 V at 42 A - peak voltage seen by protected circuit during 10/1000 μs surge; must be < IC absolute max rating |
| Peak Pulse Power PPK | 600 W - energy-handling capacity for single 10/1000 μs transients per IEC 61000-4-5 Level 4 |
| Junction Temperature Range | –55°C to +175°C - supports under-hood automotive and high-temp industrial environments without derating |
| Leakage Current ID | <1 μA at 8.1 V - ensures negligible standby power loss in battery-powered systems |
| Response Time | <1.0 ps - enables suppression of sub-nanosecond ESD events per IEC 61000-4-2 Contact Discharge |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Dimensions conform to JEDEC DO-15 standard; weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to system ground or low-side return path; conducts during positive transients when cathode is biased above anode |
| Cathode | Reverse-blocking / clamping terminal | Connected to protected line (e.g., 12V rail); blocks ≤8.1V, avalanches above ~9.0V to clamp surge energy |
Key Features

Use Scenario: Shields RS-485 transceivers from lightning-induced surges on long outdoor data runs in building automation networks. IC Role / Device Role / Timing Role: Differential-mode TVS pair (one per line) referenced to ground, placed immediately at connector entry. Use Value: Limits common-mode voltage to <15V during 10/1000μs surges, preserving transceiver integrity and preventing bus lockup. |
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 SMAJ10A | Same DO-214AC (SMA) package; 10V VBR (9.0–11.1V); 15.0V VC @ 42.8A; AEC-Q101 qualified | Surface-mount footprint requires PCB redesign; higher thermal resistance than DO-15 in high-power pulse scenarios | Select when space-constrained layouts demand SMD placement and thermal management uses thermal vias/pour |
| Vishay 1.5KE10C | Same DO-204AC (DO-15) package; 10V VBR (9.0–11.0V); 15.0V VC @ 42.0A; 1500W rating but larger case (DO-201AD) | Not pin-compatible - larger body length (9.5mm vs. 7.6mm) and different lead spacing; higher surge capacity overshoots need | Choose only if legacy 1.5KE footprint exists and >600W headroom is required for extreme ESD exposure zones |
Compared with SMAJ10A and 1.5KE10C, the P6KE10C offers identical electrical clamping performance in a through-hole DO-15 package with proven AEC-Q101 qualification, making it optimal for cost-sensitive, serviceable, or vibration-prone automotive and industrial assemblies where reworkability and mechanical robustness are prioritized over miniaturization.

FAQ
What is the polarity configuration of the P6KE10C?
The P6KE10C is a unidirectional TVS diode, with a clearly marked cathode band indicating the clamping terminal. It blocks reverse voltages up to 8.1V and avalanches in the reverse direction when transients exceed ~9.0V, while conducting forward current like a standard rectifier diode - essential for DC rail protection where polarity is fixed.
Does the P6KE10C meet AEC-Q101 qualification?
Yes, the P6KE10C 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 powertrain and chassis applications.
What is the maximum clamping voltage of the P6KE10C under surge conditions?
The P6KE10C has a maximum clamping voltage (VC) of 15.0V at 42.0A peak pulse current (IPP), measured using the standard 10/1000μs double-exponential waveform. This value represents the highest voltage imposed on the protected circuit during worst-case surge events, and must be compared directly against the absolute maximum ratings of downstream ICs.
How does the P6KE10C differ from the P6KE10A variant?
The P6KE10C and P6KE10A share identical nominal voltage (10V) and package (DO-15), but differ in VBR tightness: P6KE10C specifies 9.0–11.0V (±10%), while P6KE10A narrows this to 9.5–10.5V (±5%). The tighter tolerance of P6KE10A reduces clamping uncertainty in precision rail protection, whereas P6KE10C offers broader process yield and lower cost for general-purpose use.
Can the P6KE10C be used in bidirectional configurations?
No - the P6KE10C is strictly unidirectional. For bidirectional protection, Taiwan Semiconductor offers the P6KE10CA variant (with "CA" suffix), which integrates two opposing diodes in a single DO-15 package. Using P6KE10C in reverse-biased mode beyond its 8.1V stand-off rating risks premature breakdown and unreliable clamping behavior.
