Product details
Overview
P6KE110 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 110 V, maximum clamping voltage of 158 V at 3.9 A peak surge current, and stand-off voltage of 89.2 V - enabling robust ESD and lightning surge immunity in automotive and industrial control circuits.
For engineers reviewing the P6KE110 datasheet, P6KE110 pinout, P6KE110 application, or P6KE110 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 175°C junction temperature rating, low dynamic impedance, sub-1 ps response time, and AEC-Q101 qualification option (P6KE110H).
Technical Context
The P6KE110 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 99–121 V breakdown range (tested at 1 mA). Its clamping action limits transient energy to ≤158 V under 10/1000 µs waveform surges up to 600 W, with leakage <1 µA at 89.2 V.
Thermal design relies on its 175°C max junction temperature and derating curve per Fig.2; mechanical construction uses UL 94V-0 molded compound, pure tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 99 V / 121 V at 1 mA - defines reliable avalanche initiation window for predictable clamping onset |
| VWM | 89.2 V - maximum continuous reverse operating voltage before leakage rises above 1 µA |
| VC @ IPP | 158 V at 3.9 A - peak clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPK | 600 W - non-repetitive surge power handling capability per standard 10/1000 µs waveform |
| IR @ VWM | <1 µA - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | 175°C - supports operation in under-hood automotive and industrial environments without thermal shutdown |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass and RoHS/halogen-free compliance |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking; leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: anode (unmarked end), cathode (banded end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Ground reference / return path | Connected to system ground or low-side rail; carries full surge current during clamping |
| Cathode (banded lead) | Protected line input | Connected to the line being protected (e.g., 24 V supply rail); reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified variant available (P6KE110H) | Validated for automotive powertrain and body electronics per stress test requirements |
| 600 W peak pulse power (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation |
| Clamping voltage ≤158 V at 3.9 A | Protects 100 V-rated downstream ICs (e.g., CAN transceivers, MCU I/O) from overvoltage damage |
| Response time <1.0 ps (0 → VBR) | Engages faster than most microsecond-scale protection devices, minimizing transient penetration |
| UL 94V-0 flammability rated molding | Meets safety standards for enclosed industrial and transportation equipment enclosures |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Primary shunt TVS placed at power entry point to clamp surges before LDOs or PMICs. Use Value: Limits voltage to ≤158 V during 600 W transients, preventing latch-up or gate oxide rupture in 3.3 V/5 V logic supplies. |
Use Scenario: 24 V digital input modules receiving signals from field sensors in factory automation. IC Role / Device Role / Timing Role: Front-end protection for optocoupler or Schmitt-trigger inputs against EFT (IEC 61000-4-4) and surge coupling. Use Value: Sub-1 ps response ensures clamping occurs before EFT bursts (5 ns rise) propagate into isolation barriers. |
| LED Driver Overvoltage Clamp | Telecom Line Interface Protection |
|
Use Scenario: Constant-current LED drivers in street lighting subjected to induced lightning surges on long feeder cables. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output to absorb inductive kickback and external surges. Use Value: 175°C junction rating enables reliable operation inside thermally constrained outdoor enclosures. |
Use Scenario: Low-voltage analog interfaces (e.g., RS-485, FXS) in telecom gateways connected to outside plant wiring. IC Role / Device Role / Timing Role: First-stage protection ahead of GDT or polymer PTC, absorbing fast-rising common-mode transients. Use Value: 89.2 V stand-off voltage allows compatibility with ±12 V signaling while clamping >150 V threats. |
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 SMAJ110A | Same DO-214AC (SMA) package; 110 V nominal, 158 V clamping, but 400 W rating (vs. 600 W) | Lower surge rating limits use in high-energy automotive load dump scenarios | Select P6KE110 for higher-power 10/1000 µs surge immunity; SMAJ110A suits space-constrained PCBs where 400 W suffices |
| ON Semiconductor 1.5KE110A | Same DO-201AD (DO-27) package; identical 110 V/158 V specs but rated for 1.5 kW (10/1000 µs), larger footprint | Higher surge capacity supports harsher industrial environments but requires more board area | Choose P6KE110 for cost-optimized, AEC-Q101-capable DO-15 solution; 1.5KE110A where extreme surge margin is critical |
Compared with SMAJ110A and 1.5KE110A, the P6KE110 delivers optimal balance of 600 W surge capability, DO-15 manufacturability, and AEC-Q101 readiness - making it preferred for mid-tier automotive and industrial designs where footprint, reliability, and cost must align.

FAQ
What is the maximum clamping voltage of the P6KE110 under surge conditions?
The P6KE110 exhibits a maximum clamping voltage (VC) of 158 V when subjected to its rated peak pulse current of 3.9 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components rated for ≤160 V remain within safe operating limits during transient events.
Is the P6KE110 suitable for automotive applications?
Yes - the P6KE110H variant is AEC-Q101 qualified for automotive use, validated across temperature cycling, humidity, mechanical shock, and surge endurance tests. The base P6KE110 meets all electrical specifications required for body electronics and infotainment power rail protection, though qualification applies only to the "H" suffix version.
What is the difference between P6KE110 and P6KE110A?
The P6KE110A offers tighter breakdown voltage tolerance: 105–116 V (min/max) versus 99–121 V for the P6KE110, both tested at 1 mA. Stand-off voltage increases slightly (94.0 V vs. 89.2 V), and clamping voltage drops to 152 V at 4.1 A. These refinements improve consistency in precision-clamp designs without changing package or surge rating.
Can the P6KE110 be used in bidirectional configurations?
No - the P6KE110 is unidirectional only. Bidirectional variants in the same series carry "CA" suffixes (e.g., P6KE110CA) and feature symmetrical breakdown in both polarities. Using P6KE110 in reverse-biased AC applications risks permanent failure due to forward conduction during negative half-cycles.
What is the thermal derating behavior of the P6KE110 above 25°C ambient?
The P6KE110's peak pulse power rating decreases linearly above 25°C per the manufacturer's derating curve (Fig.2): at 75°C ambient, it retains ~70% of its 600 W rating (~420 W), and at 125°C, ~40% (~240 W). Continuous power dissipation remains limited to 5 W at 75°C with specified PCB pad layout (5 × 5 mm copper per lead).
