Product details
Overview
P6KE150CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a nominal breakdown voltage of 150 V, clamps transients to ≤207 V at 3.0 A peak surge current, and delivers sub-5 ns response time with <1 μA leakage at 128 V standoff voltage. It is AEC-Q101 qualified and housed in a DO-204AC (DO-15) package for robust ESD and lightning-induced surge suppression in DC power interfaces.
For engineers reviewing the P6KE150CAH datasheet, P6KE150CAH pinout, P6KE150CAH application, or P6KE150CAH equivalent, key selection criteria include its bidirectional clamping behavior, 150 V nominal VBR, 207 V max clamping voltage at IPP, AEC-Q101 qualification status, and DO-15 mechanical compatibility with legacy board layouts.
Technical Context
The P6KE150CAH operates as a silicon avalanche diode configured in bidirectional (symmetrical) mode, enabling protection against both positive and negative polarity transients without external polarity management. Its junction exhibits low dynamic impedance and fast carrier avalanche response, achieving typical turn-on within 5.0 ns from 0 V to VBR.
It is rated for non-repetitive 600 W peak pulse power per 10/1000 µs waveform, with thermal derating above 25 °C ambient and maximum junction temperature of 175 °C. The device meets UL 94V-0 flammability requirements and is halogen-free per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VBR | 150 V - symmetric breakdown voltage threshold for bidirectional surge conduction |
| VWM | 128 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPP | 207 V - clamping voltage at 3.0 A peak surge current, defining worst-case protected rail excursion |
| PPK | 600 W - peak pulse power handling per 10/1000 µs waveform, critical for lightning/inductive spike immunity |
| TJMAX | 175 °C - maximum junction temperature, supporting operation in under-hood automotive environments |
| Response Time | <5.0 ns - time from 0 V to VBR onset in bidirectional mode, ensuring protection before IC damage occurs |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 rating and pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (Bidirectional) | Surge conduction path | No functional polarity - terminals are interchangeable; marked cathode band is for unidirectional variants only |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating DC lines without polarity awareness |
| 600 W 10/1000 µs surge rating | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) in 12 V automotive systems |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, high-temp reverse bias, and mechanical shock |
| Low leakage <1 µA @ 128 V | Minimizes standby power loss and avoids false triggering in high-impedance sensing circuits |

Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and jump-start surges per ISO 7637-2. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed across input power pins upstream of DC-DC converters and LDOs.

IC Role / Device Role / Timing Role: Front-end transient shunt mounted at terminal block entry point before optocoupler or Schmitt trigger interface. Use Value: Clamps fast-rising EFT bursts (IEC 61000-4-4) to safe levels within 5 ns, preserving signal integrity and logic state fidelity. |
| LED Driver Surge Suppression | Telecom DC Feeder Line Protection |
|
Use Scenario: Shielding constant-current LED drivers in streetlight systems from lightning-induced surges on long outdoor wiring runs. IC Role / Device Role / Timing Role: Parallel-connected TVS across driver input terminals to divert surge energy away from switching MOSFETs and controller ICs. Use Value: Absorbs up to 600 W of surge energy without degradation, maintaining driver uptime in harsh outdoor environments. |
Use Scenario: Protecting -48 V DC power feeds in telecom base station cabinets from induced surges due to nearby lightning strikes. IC Role / Device Role / Timing Role: Bidirectional clamp installed between tip/ring lines and ground to suppress common-mode and differential-mode transients.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same 150 V nominal VBR, but SMB package (surface-mount); 600 W rating, slightly higher VC = 243 V @ 2.5 A | Requires PCB redesign for SMT layout; better suited for space-constrained, high-volume production | Select when automated assembly and smaller footprint are prioritized over through-hole serviceability |
| 1.5KE150CA | Same DO-15 package and 150 V rating, but 1500 W peak power; larger die, higher IPP = 6.9 A, VC = 220 V | Over-specified for most 600 W use cases; higher cost and thermal mass may delay response in ultra-fast ESD events | Select only when legacy 1.5KE-series inventory exists or when future-proofing for higher surge classes is required |
Compared with SMBJ150CA and 1.5KE150CA, the P6KE150CAH offers optimal balance of AEC-Q101 compliance, DO-15 through-hole compatibility, and precise 600 W surge capability-making it ideal for automotive and industrial replacements where qualification and mechanical fit are primary constraints.

FAQ
What does the 'CA' suffix indicate in P6KE150CAH?
The 'CA' suffix in P6KE150CAH denotes bidirectional configuration - meaning the device provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants (e.g., P6KE150A), the CA version has no designated anode/cathode and functions identically in either orientation, simplifying layout for AC-coupled or floating DC lines.
Is P6KE150CAH AEC-Q101 qualified?
Yes, P6KE150CAH is explicitly AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's ordering code documentation where the 'H' suffix indicates AEC-Q101 compliance. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, making P6KE150CAH suitable for automotive powertrain and body electronics applications.
What is the maximum clamping voltage of P6KE150CAH under surge conditions?
The maximum clamping voltage (VC) of P6KE150CAH is 207 V at a peak pulse current (IPP) of 3.0 A, measured using the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during a 600 W transient event and is critical for ensuring downstream components remain within their absolute maximum ratings.
How does P6KE150CAH differ from P6KE150A?
P6KE150CAH is bidirectional and AEC-Q101 qualified, whereas P6KE150A is unidirectional and not AEC-Q101 certified. The CAH variant clamps equally in both directions with no polarity marking, while P6KE150A requires correct cathode orientation and offers slightly lower VC (200 V vs. 207 V) but lacks automotive qualification and bidirectional capability.
What packaging options are available for P6KE150CAH?
P6KE150CAH is supplied in DO-204AC (DO-15) package format, available in 3,500-piece tape-and-reel (P6KE150CAH) and 1,500-piece ammo box (P6KE150CAHA0G) configurations. Both options feature pure tin-plated leads, UL 94V-0 molding compound, and comply with JESD201 Class 2 whisker resistance requirements.
