Product details
Overview
P6KE180 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 180 V, clamps transients to ≤258 V at 2.4 A peak surge current, and delivers fast response (<1.0 ps from 0 V to VBR), with stand-off voltage of 146 V and leakage <1 µA at rated VWM. It is used in automotive power supply input stages to protect ECUs against load dump and ISO 7637-2 pulses.
For engineers reviewing the P6KE180 datasheet, P6KE180 pinout, P6KE180 application, or P6KE180 equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, 180 V standoff/clamp ratio, AEC-Q101 qualification status (P6KE180H variant), junction temperature rating up to +175 °C, and compliance with ANSI/IEEE C62.35 surge waveform standards.
Technical Context
The P6KE180 operates as a silicon avalanche diode optimized for unidirectional transient suppression. Its 180 V nominal breakdown voltage (VBR = 162–198 V @ 1 mA) enables robust protection of 130–150 V DC systems, while its 258 V maximum clamping voltage (VC) at 2.4 A ensures downstream ICs remain below absolute maximum ratings during 10/1000 µs surges.
It exhibits low dynamic impedance and <1 µA reverse leakage above 146 V, supporting stable operation in high-impedance monitoring circuits. The device is rated for non-repetitive 600 W peak pulse power, with thermal derating above 25 °C per Fig.2 and junction temperature limits from –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 198 V @ 1 mA - defines reliable avalanche initiation window for predictable clamping onset |
| VWM | 146 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPP | 258 V @ 2.4 A - peak clamped voltage during 10/1000 µs surge; determines protected circuit's voltage stress ceiling |
| PPK | 600 W - non-repetitive surge power handling per 10/1000 µs waveform; sets single-event energy absorption limit |
| IR @ VWM | <1 µA - ensures negligible standby current draw in always-on protection circuits |
| TJ max | +175 °C - enables use in under-hood automotive environments and high-ambient industrial settings |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass and UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return; completes conduction path during reverse-biased surge |
| Cathode | Protected line connection | Connected to the line being protected (e.g., battery rail); avalanche conduction occurs from cathode to anode during overvoltage |
Key Features

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 SMAJ180A | Same DO-214AC (SMA) package; 180 V VBR, 258 V VC @ 2.4 A; 400 W rating (vs. 600 W) | Lower surge rating suits lower-energy transients; not AEC-Q101 qualified | Select when board space constraints favor surface-mount and surge energy is ≤400 W |
| ON Semiconductor 1.5KE180A | Same DO-201AD package; identical 180 V VBR, 258 V VC; 1500 W rating but larger footprint and higher leakage (5 µA) | Higher power handling supports harsher environments; requires larger PCB pad area | Select when system-level surge testing exceeds 600 W and layout allows larger axial package |
Compared with SMAJ180A and 1.5KE180A, the P6KE180 offers optimal balance of 600 W surge capability, DO-15 footprint compatibility, and AEC-Q101 availability-making it preferred for cost-sensitive, space-constrained automotive and industrial designs requiring validated reliability.

FAQ
What is the maximum clamping voltage of the P6KE180 under surge conditions?
The P6KE180 has a maximum clamping voltage (VC) of 258 V when subjected to its rated peak pulse current of 2.4 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected downstream components remain within their absolute maximum voltage ratings during standardized surge events. The P6KE180 maintains this clamping performance across its full operating temperature range.
Is the P6KE180 suitable for automotive applications?
Yes-the P6KE180H variant is explicitly AEC-Q101 qualified for automotive use, having passed stress tests including temperature cycling, humidity, mechanical shock, and high-temperature operating life. While the base P6KE180 is not AEC-Q101 certified, its construction, materials (halogen-free, RoHS-compliant), and 175 °C junction rating align with automotive environmental requirements. Always specify P6KE180H for production automotive designs requiring qualification evidence.
What is the difference between P6KE180 and P6KE180A?
The P6KE180A features tighter breakdown voltage tolerance: 171–189 V (min/max) versus 162–198 V for the P6KE180, both tested at 1 mA. The P6KE180A also has a slightly higher stand-off voltage (154 V vs. 146 V) and lower clamping voltage (246 V vs. 258 V at 2.5 A). These differences make the P6KE180A preferable where precise voltage threshold control and marginally better clamping are required, while the P6KE180 offers broader tolerance for cost-sensitive applications.
Can the P6KE180 be used in bidirectional configurations?
No-the P6KE180 is a unidirectional TVS diode, intended for DC line protection with defined polarity (cathode toward the protected line). For bidirectional AC or floating-line protection, select the CA-suffixed variant (e.g., P6KE180CA) or bipolar types explicitly marked for dual-direction operation. Using P6KE180 in reverse-biased AC applications risks forward conduction and permanent damage due to its asymmetric structure.
What packaging options are available for the P6KE180?
The P6KE180 is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 units per tape-and-reel (P6KE180) and 1,500 units per ammo box (P6KE180A0G). Lead finish is pure tin, compliant with J-STD-002 for solderability, and the molding compound meets UL 94V-0 flammability rating. No surface-mount or alternate lead-form options exist for this part number.
