Product details
Overview
P6KE150A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supply inputs, DC bus lines, and industrial control interfaces. It features a 150V nominal breakdown voltage (VBR min/max: 143–158V), 128V stand-off voltage (VWM), clamps to ≤207V at 3.0A peak surge current, and operates across –55°C to +175°C junction temperature.
For engineers reviewing the P6KE150A datasheet, P6KE150A pinout, P6KE150A application, or P6KE150A equivalent, this device is selected for high-energy ESD and lightning surge immunity in 24/48V industrial systems, automotive body electronics, and AC/DC front-end protection where fast response (<1ps), low dynamic impedance, and AEC-Q101 qualification (H-suffix variant) are critical.
Technical Context
The P6KE150A employs a silicon avalanche diode structure optimized for unidirectional clamping with tightly controlled VBR tolerance (±5% typical for "A" grade). Its 10/1000μs waveform surge rating of 600W is derated linearly above 25°C ambient per Fig.2, maintaining reliable operation up to 175°C junction temperature.
With a maximum reverse leakage ID of 1μA at 128V (VWM), it minimizes standby power loss in always-on circuits. Its clamping voltage VC of 207V at IPP = 3.0A ensures downstream ICs (e.g., MCU power rails, gate drivers, sensor interfaces) remain below absolute maximum ratings during transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 150V - defines rated clamping threshold for system-level surge coordination |
| Breakdown Voltage VBR | 143–158V @ 1mA - tight ±5% tolerance enables precise overvoltage trip point setting |
| Stand-Off Voltage VWM | 128V - maximum continuous reverse voltage before significant leakage begins |
| Peak Pulse Power PPK | 600W @ 10/1000μs - sustains single high-energy surges common in industrial mains and motor drives |
| Clamping Voltage VC | ≤207V @ 3.0A IPP - limits voltage seen by protected ICs during worst-case transient events |
| Junction Temperature Range | –55°C to +175°C - supports under-hood automotive and high-ambient industrial deployments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with through-hole assembly and manual repair |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, epoxy-molded, cathode band marked on one end. 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 path / surge return node | Connected to ground or low-impedance return plane; carries full surge current during clamping |
| Cathode | Protected line input / high-side connection | Connected to the line being protected (e.g., +24V rail); blocks reverse leakage up to VWM |
Key Features
| Feature | Design Value |
|---|---|

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 SMAJ150A | Same DO-214AC (SMA) package; 150V VBR (143–158V), 207V VC @ 3.0A, but 400W PPK rating | Suitable for space-constrained SMT designs; lower surge capacity requires parallel placement or upstream filtering for 600W events | Select when board area is limited and surge threat level is ≤400W (e.g., secondary-side protection). |
| ON Semiconductor 1.5KE150A | Same DO-201AD (DO-27) package; identical 150V VBR range and 207V VC, but rated for 1500W PPK (10/1000μs) | Over-spec'd for most 600W use cases; larger package footprint and higher cost; better suited for high-reliability aerospace or grid-tied inverters | Select when future-proofing against higher surge standards or when legacy DO-27 footprint must be retained. |
Compared with Littelfuse SMAJ150A and ON Semi 1.5KE150A, the P6KE150A delivers optimal balance of 600W surge handling, DO-15 through-hole compatibility, and cost efficiency for industrial and automotive front-end protection-without over-engineering or sacrificing manufacturability.

FAQ
What is the maximum clamping voltage of the P6KE150A under surge conditions?
The P6KE150A has a maximum clamping voltage (VC) of 207V when subjected to its rated peak pulse current of 3.0A using the 10/1000μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during transient events, ensuring downstream components remain within safe operating ranges.
Is the P6KE150A suitable for automotive applications?
Yes-the P6KE150A is offered in an AEC-Q101 qualified version (P6KE150AH) that meets stress test requirements for automotive electronics. While the base P6KE150A is not AEC-Q101 certified, its 175°C junction rating, low leakage, and robust surge performance make it widely used in non-safety-critical automotive subsystems such as body control modules and lighting drivers.
How does the P6KE150A differ from the non-"A" grade P6KE150?
The P6KE150A features tighter VBR tolerance (143–158V vs. 135–165V for P6KE150), lower clamping voltage (207V vs. 215V), and improved consistency in leakage and temperature coefficient. These enhancements improve predictability in precision protection schemes and reduce design margin uncertainty compared to the standard-grade P6KE150.
What is the recommended PCB layout practice for the P6KE150A?
For optimal transient suppression, place the P6KE150A as close as possible to the protected interface connector with minimal trace length-ideally <5mm from cathode to line and anode to ground plane. Use wide, low-inductance traces and avoid vias in the surge current path; the DO-15 leads should be soldered directly to solid copper pours to maximize thermal dissipation and minimize clamping delay.
Does the P6KE150A require derating at elevated ambient temperatures?
Yes-the P6KE150A's peak pulse power capability must be derated linearly above 25°C ambient, per Figure 2 in the datasheet. At 75°C ambient, its 600W rating drops to approximately 480W; at 125°C, it falls to ~300W. Designers must verify worst-case ambient + self-heating stays within the derated PPK envelope for the intended surge profile.
