Product details
Overview
P6KE10CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 10.5 V breakdown voltage at 1 mA test current - deployed on signal lines of automotive sensor units and industrial I/O interfaces.
For engineers reviewing the P6KE10CAHE3/54 datasheet, P6KE10CAHE3/54 pinout, P6KE10CAHE3/54 application, or P6KE10CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification for automotive use, DO-15 mechanical compatibility, and verified 175 °C junction temperature rating under transient stress.
Technical Context
This device operates as a voltage-clamped shunt protector: during overvoltage events exceeding its standoff voltage (VWM = 8.55 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Designed for unidirectional and bidirectional configurations, P6KE10CAHE3/54 supports symmetric clamping in both polarities - critical for AC-coupled signal lines and differential bus protection. Thermal resistance (RθJL = 20 °C/W) and 5.0 W steady-state power dissipation enable reliable operation without heatsinking in typical PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 9.50 V / 10.5 V at 1 mA - defines precise avalanche initiation window for repeatable clamping onset |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 10 μA |
| VC @ IPPM | 14.5 V at 41.4 A - clamping voltage under 10/1000 μs surge, limiting protected IC voltage stress |
| PPPM | 600 W - peak transient power handling capacity with 0.01 % duty cycle, enabling robust surge immunity |
| TJ max | +175 °C - extended junction temperature rating supports under-hood automotive deployment |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; bidirectional construction has no polarity marking - both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals conduct identically during positive or negative overvoltage events - no orientation required during placement |
| Case (body) | Mechanical mounting surface | Non-conductive epoxy body provides electrical isolation; lead length ≥ 25.4 mm ensures creepage compliance per UL 497B |
Key Features

| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-to-line) without degradation when properly mounted |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS sensor interfaces |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation prevents flame propagation in high-energy fault conditions |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD > 15 kV contact discharge) |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at connector entry point to clamp surges before reaching signal conditioning circuitry. Use Value: Limits voltage seen by downstream op-amps and ADCs to ≤14.5 V during 40 A transients - preventing latch-up and permanent damage. | Use Scenario: Safeguarding digital input/output channels on programmable logic controllers interfacing with 24 V DC field devices subject to inductive kickback. IC Role / Device Role / Timing Role: Bidirectional clamping element across each I/O line to absorb reverse-polarity connection errors and relay coil flyback energy. Use Value: Enables reliable operation under repeated 600 W surges without parameter drift - verified over 1000+ surge cycles per AEC-Q101 stress testing. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
Use Scenario: Secondary-side surge suppression in AC/DC adapters for smart home devices, guarding against mains-borne transients entering low-voltage DC rails. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between +5 V rail and ground to clamp fast-rising spikes from nearby switching noise or ESD coupling. Use Value: Maintains 8.55 V working voltage margin while clamping to 14.5 V - preserving regulation integrity of LDOs and PMICs downstream. | Use Scenario: Primary protection for Ethernet PHY interfaces and DSL line drivers exposed to lightning-induced surges on twisted-pair cabling. IC Role / Device Role / Timing Role: Symmetric clamping device across differential pairs to limit common-mode overvoltage without distorting signal integrity. Use Value: Bidirectional operation ensures equal clamping for ±1 kV transients - meeting GR-1089-CORE Level 3 telecom surge requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same VWM (8.55 V) and VC (14.5 V), but 600 W rating in smaller SMB package (JEDEC DO-214AA); lower RθJA (50 °C/W vs. 75 °C/W) | Better suited for space-constrained designs; not AEC-Q101 qualified - limited to commercial-grade systems | Select SMBJ10CA when board area is constrained and automotive qualification is not required. |
| 1.5KE10CA | Higher peak pulse power (1500 W), same DO-15 package; VC = 17.0 V at 87.8 A - looser clamping tolerance | Used where higher surge energy must be absorbed (e.g., industrial motor drives), accepting higher clamping voltage | Choose 1.5KE10CA only if system-level analysis confirms 17.0 V clamping is acceptable for protected ICs. |
Compared with SMBJ10CA and 1.5KE10CA, P6KE10CAHE3/54 uniquely balances AEC-Q101 qualification, DO-15 legacy footprint compatibility, and tight 14.5 V clamping - making it optimal for cost-sensitive automotive and industrial upgrades requiring drop-in replacement of older P6KE series parts.

FAQ
What is the clamping voltage of P6KE10CAHE3/54 under a standard 10/1000 μs surge?
The P6KE10CAHE3/54 clamps to a maximum of 14.5 V when subjected to its rated peak pulse current of 41.4 A using the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and confirmed in Vishay's datasheet revision 27-Sep-2021, Document Number 88369. The clamping performance remains consistent across both polarities due to its bidirectional design.
Is P6KE10CAHE3/54 suitable for automotive applications?
Yes, P6KE10CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 94 V-0 molding compound meet stringent automotive reliability requirements. The HE3 suffix denotes AEC-Q101 qualification, distinguishing it from commercial-grade E3 variants.
How does the bidirectional configuration of P6KE10CAHE3/54 affect PCB layout?
The bidirectional nature of P6KE10CAHE3/54 eliminates polarity concerns during placement - no cathode band or marking exists on the DO-15 body. This simplifies assembly and reduces risk of misorientation. Layout requires symmetric trace routing to both terminals and adequate copper pour for thermal dissipation, leveraging its 20 °C/W junction-to-lead thermal resistance.
What is the standoff voltage (VWM) of P6KE10CAHE3/54, and why does it matter?
P6KE10CAHE3/54 has a standoff voltage (VWM) of 8.55 V, meaning it remains non-conductive up to this DC or RMS voltage level with leakage <10 μA. This parameter ensures normal circuit operation without loading or power loss, while still allowing rapid avalanche conduction when transients exceed this threshold - balancing protection sensitivity and operational stability.
Can P6KE10CAHE3/54 replace older P6KE10CA parts in existing designs?
Yes, P6KE10CAHE3/54 is a direct functional and mechanical replacement for legacy P6KE10CA variants, retaining identical DO-15 package dimensions, electrical specifications, and pinout. The HE3 suffix adds AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - enhancing reliability without requiring PCB or schematic changes.
