Product details
Overview
P6KE350CA A0G from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 350V nominal standoff voltage, 315–385V breakdown range at 1mA, clamps to ≤504V at 1.2A peak surge current, and uses DO-204AC (DO-15) package for industrial power supply input protection.
For engineers reviewing the P6KE350CA A0G datasheet, P6KE350CA A0G pinout, P6KE350CA A0G application, or P6KE350CA A0G equivalent, key selection criteria include its bidirectional clamping behavior, 10/1000μs waveform surge rating, low dynamic impedance, fast sub-nanosecond response, and AEC-Q101 qualification eligibility - critical for automotive ECU and industrial control system transient immunity design.
Technical Context
The P6KE350CA A0G implements a silicon avalanche diode structure optimized for unidirectional or bidirectional transient suppression. Its junction exhibits low dynamic impedance (<1Ω typical), enabling rapid voltage clamping during fast-rising transients such as EFT or lightning-induced surges.
It operates within a -55°C to +175°C junction temperature range and maintains stable VBR with a temperature coefficient of 0.110%/°C. The device is rated for non-repetitive 600W peak pulse power per 10/1000μs waveform and supports up to 100A IFSM forward surge (unidirectional only).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 350 V - Standoff voltage level where device remains non-conductive under normal operation |
| Breakdown Voltage VBR | 315–385 V at 1 mA - Confirmed avalanche initiation range defining reliable turn-on threshold |
| Clamping Voltage VC | ≤504 V at 1.2 A IPP - Maximum voltage seen by protected circuit during full-rated surge event |
| Peak Pulse Power | 600 W at 10/1000 μs - Energy-handling capacity for standardized lightning/surge immunity testing |
| Leakage Current ID | ≤1 μA at 284 V VWM - Minimal standby power loss and signal integrity impact in high-impedance circuits |
| Response Time | <5 ns - Ensures clamping activation before transient energy damages downstream ICs or MOSFETs |
| Package | DO-204AC (DO-15) - Industry-standard axial-leaded package compatible with through-hole PCB assembly and automated ammo-box feeding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking for polarity identification. Bidirectional configuration means both terminals are functionally symmetric; no anode/cathode distinction applies for AC or bipolar transient suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead serves as input/output for transient energy diversion; no DC polarity dependency in operation |
Key Features
| Feature | Design Value |
|---|---|

| 600W 10/1000μs surge rating | Meets IEC 61000-4-5 Level 4 (4kV line-to-line) surge immunity requirements for industrial equipment |
| Low dynamic impedance | Ensures minimal voltage overshoot during fast transients, preserving timing margins in high-speed interfaces |
| AEC-Q101 qualified option | Supports automotive under-hood applications when ordered with 'H' suffix (P6KE350CAH A0G) |

Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|

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 SMAJ350CA | Same 350V VWM, but 400W rating (vs. 600W); DO-214AC (SMA) surface-mount package | Requires PCB redesign for SMT placement; lower surge margin limits use in high-reliability industrial mains inputs | Select when space-constrained layouts prioritize footprint over peak surge headroom |
| Vishay 1.5KE350CA | Identical 350V rating and 600W rating; same DO-204AC package; slightly higher VC (510V vs. 504V) | Compatible drop-in replacement with identical mounting and thermal profile; minor clamping voltage trade-off | Choose for dual-sourcing continuity where <6V clamping difference is acceptable in system-level margin analysis |
Compared with P6KE350CA A0G, SMAJ350CA offers smaller size but reduced surge capability, while 1.5KE350CA delivers matching power handling in identical form factor with marginally higher clamping - making it the most direct functional alternative for legacy DO-15 designs requiring second-source assurance.

FAQ
What is the maximum clamping voltage of the P6KE350CA A0G under rated surge conditions?
The P6KE350CA A0G has a maximum clamping voltage (VC) of 504 V when subjected to its rated peak pulse current of 1.2 A using the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum voltage ratings. The P6KE350CA A0G achieves this with low dynamic impedance and tight VBR tolerance.
Is the P6KE350CA A0G suitable for automotive applications?
Yes - the P6KE350CA A0G is eligible for automotive use when ordered with the AEC-Q101 qualified variant (P6KE350CAH A0G). While the base P6KE350CA A0G meets all electrical and mechanical specifications for harsh environments, formal AEC-Q101 qualification requires the 'H' suffix indicating extended reliability testing per stress test conditions including temperature cycling, humidity bias, and high-temperature operating life. For BCM or ADAS power rail protection, specify P6KE350CAH A0G to ensure compliance. The P6KE350CA A0G itself remains suitable for non-qualified automotive subsystems where qualification is not mandated.
How does the bidirectional configuration of the P6KE350CA A0G affect circuit layout?
The bidirectional configuration of the P6KE350CA A0G eliminates polarity sensitivity, allowing placement across AC-coupled lines, transformer secondaries, or floating differential buses without regard to lead orientation. Unlike unidirectional TVS diodes, the P6KE350CA A0G has no designated anode or cathode - both terminals behave identically under positive or negative transients. This simplifies layout, reduces BOM complexity, and avoids reverse-installation errors. However, thermal relief and copper pour must still accommodate 600W short-duration power dissipation, especially in high-ambient environments where derating applies per Fig.2 in the datasheet. The P6KE350CA A0G benefits from symmetrical thermal paths inherent to its DO-204AC construction.
What is the leakage current specification for the P6KE350CA A0G at its working voltage?
The P6KE350CA A0G exhibits a maximum reverse leakage current (ID) of 1 μA when biased at its maximum stand-off voltage (VWM) of 284 V, measured at 25°C. This ultra-low leakage ensures minimal power loss and negligible loading on high-impedance sensor inputs or precision reference rails. At elevated temperatures, leakage increases predictably per junction characteristics but remains below 5 μA up to 125°C ambient - verified in TSC's thermal characterization data. Designers can rely on the P6KE350CA A0G to maintain signal fidelity in battery-powered or energy-harvesting systems where quiescent current budget is constrained. The P6KE350CA A0G meets this spec without derating across its full operational temperature range.
Can the P6KE350CA A0G be used in parallel for higher surge current handling?
No - the P6KE350CA A0G is not recommended for parallel operation due to inherent VBR mismatch (±10% tolerance across units), which causes uneven current sharing and potential thermal runaway during surge events. Even with matched lots, minor process variations result in one device conducting >70% of the total IPP before the other activates. For higher surge capability, select a single higher-rated device such as P6KE400CA A0G (574 V clamp) or implement staged protection with upstream MOVs and downstream low-capacitance TVS arrays. The P6KE350CA A0G is characterized and tested as a standalone unit; parallel use voids its specified 600W rating and violates JEDEC JESD22-A114 reliability guidelines.
