Product details
Overview
P6KE110A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 110 V, clamping voltage of 152 V at 4.1 A peak surge current, stand-off voltage of 94.0 V, and low dynamic impedance for effective surge suppression in automotive and industrial electronics.
For engineers reviewing the P6KE110A datasheet, P6KE110A pinout, P6KE110A application, or P6KE110A equivalent, key selection criteria include its DO-204AC (DO-15) axial package, AEC-Q101 qualification (H-suffix variant), 175°C maximum junction temperature, and compliance with ANSI/IEEE C62.35 for transient immunity design.
Technical Context
The P6KE110A operates as a unidirectional avalanche diode with precise breakdown voltage tolerance (105–116 V at 1 mA test current) and fast response time (<1.0 ps from 0 V to VBR). Its clamping performance is characterized by a maximum VC of 152 V at IPP = 4.1 A under 10/1000 µs waveform, ensuring reliable protection against ESD and lightning-induced transients.
Thermal derating follows a linear curve above 25°C ambient, maintaining 600 W peak pulse power capability at TA ≤ 25°C and reducing to ~400 W at 75°C. The device uses a single-die construction in a DO-204AC molded package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains high-energy transients without failure in automotive load-dump or inductive switching events |
| Stand-Off Voltage (VWM) | 94.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA, defining safe DC rail margin |
| Breakdown Voltage (VBR) | 105–116 V at 1 mA - tight tolerance ensures predictable turn-on during overvoltage, critical for system-level immunity |
| Clamping Voltage (VC) | 152 V at 4.1 A - limits downstream voltage stress to protected ICs or sensors during surge events |
| Junction Temperature Range | −55 °C to +175 °C - supports operation in under-hood automotive and industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass and UL 94V-0 molding compound |
| AEC-Q101 Qualified | Yes (H-suffix variant) - validated for automotive electronic modules requiring reliability per stress-test standards |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking; two-terminal device (anode and cathode). Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge or bias conditions |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); avalanches into conduction when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | Enables rapid voltage clamping with minimal overshoot during fast transients (e.g., EFT bursts) |
| Typical IR < 1 µA @ VWM | Minimizes standby power loss and avoids false triggering on stable DC rails |
| UL Recognized (E326243) | Validates safety compliance for end-equipment certification in North America |
| RoHS & Halogen-Free | Meets IEC 61249-2-21 and environmental directives for green manufacturing and disposal |
| Fast response time | <1.0 ps rise to VBR ensures protection before sensitive logic or analog circuitry is damaged |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

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, 152 V clamping, but rated for 400 W (not 600 W) | Lower peak power rating limits use in high-energy automotive load-dump scenarios | Select P6KE110A where 600 W surge capability is required; choose SMAJ110A only if board space constraints favor surface-mount |
| Vishay 1.5KE110A | Same DO-204AC (DO-15) package and 110 V rating; identical 152 V clamping, but rated for 1500 W peak power | Higher power rating enables longer surge duration handling, but larger thermal mass may affect PCB layout | Choose P6KE110A for cost-sensitive AEC-Q101-compliant designs; select 1.5KE110A only when >600 W surge margin is mandatory |
Compared with SMAJ110A and 1.5KE110A, the P6KE110A delivers optimal balance of AEC-Q101 qualification, 600 W surge capacity, and DO-15 through-hole compatibility-making it ideal for automotive body control modules and industrial power supplies where reliability and legacy assembly processes matter.

FAQ
What is the maximum clamping voltage of the P6KE110A under standard test conditions?
The P6KE110A has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 µs surge current of 4.1 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during transient events. The P6KE110A maintains this clamping performance across its full operating temperature range.
Is the P6KE110A AEC-Q101 qualified?
Yes, the P6KE110A is AEC-Q101 qualified - specifically the H-suffix variant (e.g., P6KE110AH) meets the full stress-test requirements for automotive discrete semiconductors. The base P6KE110A part is manufactured to the same process and material specifications; qualification status is confirmed in Taiwan Semiconductor's official documentation and ordering code P6KE110AH.
What is the stand-off voltage (VWM) of the P6KE110A, and why does it matter?
The P6KE110A has a stand-off voltage (VWM) of 94.0 V, meaning it remains non-conductive with leakage <1 µA up to this reverse voltage. This parameter ensures the P6KE110A does not interfere with normal 12 V or 24 V system operation while providing headroom before clamping begins - critical for avoiding false triggering in stable power rails.
Can the P6KE110A be used in bidirectional configurations?
No, the P6KE110A is a unidirectional TVS diode and must be used with correct polarity - cathode connected to the protected line. For bidirectional protection, Taiwan Semiconductor offers the P6KE110CA variant (with CA suffix), which provides symmetrical clamping in both directions and is electrically distinct from the P6KE110A.
What package type does the P6KE110A use, and what are its mechanical highlights?
The P6KE110A uses the DO-204AC (DO-15) axial leaded package, featuring pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability-rated molding compound, and JESD201 Class 2 whisker resistance. Its 0.400 g mass and standardized footprint support automated through-hole assembly and high-reliability mounting on copper pads.
