Product details
Overview
P6KE150CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 150V nominal breakdown voltage (VBR min/max: 135V–165V), 121V stand-off voltage (VWM), clamps to ≤215V at 2.9A peak surge current, and uses DO-204AC (DO-15) axial package for industrial power supply input stage protection.
For engineers reviewing the P6KE150CH datasheet, P6KE150CH pinout, P6KE150CH application, or P6KE150CH equivalent, this AEC-Q101 qualified TVS offers verified clamping performance under 10/1000μs surges, low dynamic impedance, sub-1ps response time, and <1μA leakage above 10V - critical for automotive body electronics, industrial PLC I/O protection, and PoE-powered device front-end hardening.
Technical Context
The P6KE150CH operates as a unidirectional avalanche diode with precise VBR tolerance (±10% around 150V) and temperature coefficient of 0.108%/°C. Its junction structure delivers fast turn-on (<1ps from 0V to VBR) and stable clamping across -55°C to +175°C operating range.
It sustains non-repetitive 600W peak pulse power per 10/1000μs waveform, derates linearly above 25°C ambient, and maintains ≤215V clamping voltage (VC) at 2.9A IPP - enabling robust protection against IEC 61000-4-5 Level 4 surges without upstream current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 121 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below system DC rail (e.g., 130V bus) |
| VBR (min/max) | 135 V / 165 V - guaranteed avalanche onset range at 1 mA test current; defines minimum overvoltage threshold for clamping activation |
| VC @ IPP | ≤215 V at 2.9 A - maximum clamped voltage during 10/1000μs surge; determines worst-case stress on downstream ICs |
| PPK | 600 W - peak pulse power handling per standard 10/1000μs waveform; validates compliance with IEC 61000-4-5 surge immunity |
| IR @ VWM | <1 μA - ultra-low reverse leakage at rated stand-off voltage; ensures minimal power loss and no thermal runaway in standby |
| TJ max | +175 °C - maximum junction temperature; supports operation in under-hood automotive or high-ambient industrial enclosures |
| Package | DO-204AC (DO-15) - axial-leaded, UL 94V-0 molded case with tin-plated leads; compatible with wave soldering and manual rework |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking. Two-terminal device: anode (unmarked end) and cathode (banded end). No internal circuitry - functions as single-junction unidirectional avalanche diode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | DC return path / ground reference | Connected to system ground or low-side return; completes clamping path during positive transients |
| Cathode | Protected line input | Connected to protected node (e.g., 130V DC rail); conducts avalanche current when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and body ECUs |
| 600W 10/1000μs surge rating | Meets IEC 61000-4-5 Level 4 (4kV line-earth, 2kV line-line) without external series impedance |
| Clamping voltage ≤215V | Ensures protected 150V-rated components remain within absolute maximum ratings during surge events |
| Response time <1ps | Activates before most semiconductor damage mechanisms initiate - critical for protecting fast-switching MOSFET gates |
| UL 94V-0 flammability rating | Self-extinguishing epoxy prevents fire propagation in fault conditions per safety-critical designs |
Applications
| Automotive Power Distribution | Industrial DC Power Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ150A | Same DO-214AC (SMA) package; 150V VBR, 219V [email protected]; 400W rating; not AEC-Q101 qualified | Lower surge rating limits use to non-automotive industrial or telecom; requires layout change due to surface-mount footprint | Select when cost-sensitive consumer-grade designs prioritize SMT assembly over automotive qualification |
| ON Semiconductor 1.5KE150A | Same DO-201AD (DO-201) axial package; 150V VBR, 219V [email protected]; 1500W rating; AEC-Q101 available only on select variants | Higher power rating allows longer surge duration handling but larger package increases board space by 30% | Select when legacy DO-201AD footprint compatibility is required and higher surge margin justifies added size |
Compared with SMAJ150A and 1.5KE150A, the P6KE150CH provides AEC-Q101 qualification in the compact DO-15 form factor with optimized 600W/215V clamping balance - making it the preferred choice for space-constrained automotive and industrial DC power protection where certification and reliability are mandatory.

FAQ
What is the maximum clamping voltage of the P6KE150CH under a 10/1000μs surge?
The P6KE150CH has a maximum clamping voltage (VC) of 215 V when subjected to its rated peak surge current of 2.9 A using the standard 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components experience no more than 215 V during surge events - critical for protecting 200V-rated capacitors and 250V MOSFETs in 130V systems.
Is the P6KE150CH suitable for bidirectional surge protection?
No, the P6KE150CH is a unidirectional TVS diode intended only for DC line protection with defined polarity. Its cathode band must be oriented toward the protected voltage rail. For bidirectional AC or data-line protection, the P6KE150A variant (symmetrical breakdown) or dedicated bidirectional TVS like P6KE150CA should be used instead - the "H" suffix in P6KE150CH explicitly denotes unidirectional AEC-Q101 qualification.
Does the P6KE150CH meet automotive qualification standards?
Yes, the P6KE150CH is AEC-Q101 qualified per Version P2203 documentation, confirming validation for automotive applications including under-hood temperature cycling, mechanical shock, and humidity testing. This makes it suitable for use in engine control units, body control modules, and ADAS power supplies where reliability under extended temperature (-55°C to +175°C) and vibration is mandatory.
What is the leakage current specification for the P6KE150CH at its stand-off voltage?
The P6KE150CH exhibits maximum reverse leakage current (ID) of less than 1 μA when biased at its 121 V stand-off voltage (VWM) and tested at 25°C. This ultra-low leakage ensures negligible power loss in always-on systems and avoids thermal drift issues in precision voltage monitoring circuits - a key advantage over older 1N6267-style TVS diodes with higher IR.
Can the P6KE150CH be used in parallel for higher surge current handling?
No, the P6KE150CH is not recommended for parallel connection due to inherent VBR mismatch between units, which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a single higher-rated device such as the 1.5KE150A (1500W), or implement staged protection with series impedance - the P6KE150CH's design assumes standalone operation per its 600W rating and DO-15 thermal profile.
