Product details
Overview
P6KE10HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary-level overvoltage protection of DC power rails and signal lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability - deployed in ECU power input stages to suppress load-dump and inductive switching transients.
For engineers reviewing the P6KE10HE3/54 datasheet, P6KE10HE3/54 pinout, P6KE10HE3/54 application, or P6KE10HE3/54 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJL = 20 °C/W), unidirectional polarity marking, and RoHS-compliant HE3 whisker-tested leads - all critical for automotive front-end protection design validation.
Technical Context
This TVS operates as a silicon avalanche diode with glass-passivated junction, triggering when reverse voltage exceeds its 9.5–10.5 V breakdown range (IT = 1.0 mA). Its low incremental surge resistance enables rapid clamping response (<1 ns), limiting transient energy delivered to downstream components during 10/1000 μs surges up to 41.4 A.
Thermal performance is defined by RθJL = 20 °C/W and RθJA = 75 °C/W, supporting operation from –55 °C to +175 °C junction temperature. The HE3 suffix confirms AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and matte tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage before leakage exceeds 10 μA; sets upper limit for protected line's nominal DC voltage. |
| VBR min/max | 9.50 V / 10.5 V at IT = 1.0 mA - Confirmed breakdown window ensures predictable turn-on without premature conduction under normal bias. |
| VC | 14.5 V at IPPM = 41.4 A - Clamping voltage defines worst-case overvoltage seen by downstream ICs during full-rated surge. |
| PPPM | 600 W (10/1000 μs) - Peak transient energy absorption capacity; determines survivability against ISO 7637-2 Pulse 5a load-dump events. |
| IFSM | 100 A (8.3 ms half-sine) - Surge current rating validates robustness against repetitive inrush or fault currents in automotive power systems. |
| TJ max | +175 °C - High junction temperature rating supports placement near hot components (e.g., power MOSFETs) without derating penalties. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance enables effective heat transfer to PCB copper pour or heatsinked leads. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Cathode indicated by color band on one end; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward current path / low-side reference | Connected to ground or lower-potential node; forms return path during clamping of positive transients on cathode side. |
| Cathode (banded lead) | Transient voltage sensing / clamping node | Connected to protected line (e.g., 12 V battery rail); avalanche conduction begins here when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Enables stable, repeatable avalanche characteristics over lifetime and temperature; eliminates surface degradation risks in humid environments. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control units and body electronics, with extended temperature cycling and mechanical shock testing. |
| 600 W peak pulse power (10/1000 μs) | Provides sufficient margin to absorb ISO 16750-2 and ISO 7637-2 Pulse 5a transients without degradation across 1000+ surge events. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on protected devices - e.g., keeps 12 V system transients below 15 V, within most MCU IO tolerances. |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under high-humidity, high-temperature conditions typical in under-hood automotive modules. |
Applications
| Automotive ECU Power Input Protection | Industrial PLC Digital I/O Protection |

IC Role / Device Role / Timing Role: Placed across VDD and GND rails of half-bridge driver ICs, conducting only during transient overvoltage events. Use Value: Enables use of cost-optimized 20 V-rated drivers instead of 30 V+ variants by guaranteeing clamped rail voltage stays ≤14.5 V during 600 W surges. |
Use Scenario: Guards AC/DC adapter output stages in VoIP phones and DSL modems against lightning-induced surges coupled via Ethernet or power lines. IC Role / Device Role / Timing Role: Final-stage TVS on regulated 5 V or 12 V output, acting as last-resort clamp after MOV and fuse coordination. Use Value: Provides precise, low-VC clamping (14.5 V) to protect sensitive PHY ICs rated for 16 V absolute maximum, avoiding overdesign with higher-VBR parts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VWM (8.55 V) and VC (14.5 V), but SMC package (higher thermal mass); 600 W rating confirmed. | Surface-mount footprint replaces through-hole DO-15; requires PCB rework but improves board density and automated assembly yield. | Select SMBJ10A when migrating to SMT production or needing improved thermal dissipation in space-constrained designs. |
| 1.5KE10A | Same DO-204AC package and electrical specs, but commercial-grade (E3 suffix only); not AEC-Q101 qualified or whisker-tested. | Lacks automotive qualification and enhanced lead finish; suitable for industrial/commercial applications where extended reliability testing is not mandated. | Choose 1.5KE10A for cost-sensitive non-automotive designs where AEC-Q101 compliance and JESD 201 Class 2 are not required. |
Compared with SMBJ10A and 1.5KE10A, P6KE10HE3/54 uniquely combines AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and through-hole DO-15 packaging - making it the only option among the three validated for under-hood automotive deployment without layout change or thermal derating.

FAQ
What is the clamping voltage of P6KE10HE3/54 and how is it measured?
The P6KE10HE3/54 has a maximum clamping voltage (VC) of 14.5 V, measured at its peak pulse current (IPPM) of 41.4 A using a standardized 10/1000 μs waveform. This value represents the highest voltage the device allows across its terminals during a full-rated transient event - a critical parameter for ensuring protected ICs remain within their absolute maximum voltage ratings. The test condition is explicitly defined in Vishay document 88369, Figure 1 and Table on page 2.
Is P6KE10HE3/54 suitable for automotive applications?
Yes, P6KE10HE3/54 is AEC-Q101 qualified and carries the HE3 suffix, confirming compliance with automotive reliability standards including temperature cycling, mechanical shock, and humidity testing. Its –55 °C to +175 °C operating range, JESD 201 Class 2 whisker-resistant leads, and DO-204AC package make it suitable for under-hood ECUs, body control modules, and infotainment power supplies where sustained reliability under harsh conditions is mandatory.
How does the HE3 suffix differ from E3 in P6KE10HE3/54?
The HE3 suffix in P6KE10HE3/54 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance and JESD 201 Class 1A whisker testing only. HE3 parts undergo additional automotive-grade stress screening and are approved for use in safety-critical vehicle subsystems - a distinction confirmed in Vishay's ordering information table (page 3, Document 88369) and material categorization policy.
What is the thermal resistance of P6KE10HE3/54 and why does it matter?
P6KE10HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to the PCB copper or external heatsink via its axial leads. This low value is essential for sustaining repeated surge events without thermal runaway - especially in automotive applications where ambient temperatures exceed 100 °C and duty cycles may approach 0.01 %, as specified in Vishay's derating curves (Figure 2 and 5, Document 88369).
Can P6KE10HE3/54 be used in bi-directional protection circuits?
No, P6KE10HE3/54 is a uni-directional TVS diode, identified by its "A" suffix and cathode band marking. Bi-directional variants require the "CA" suffix (e.g., P6KE10CA) and lack polarity marking. Using P6KE10HE3/54 in bi-directional applications would leave the forward-biased direction unprotected - a limitation clearly stated in Vishay's "DEVICES FOR BI-DIRECTION APPLICATIONS" section and polarity note on page 1 of Document 88369.
