Product details
Overview
P6KE10HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, 8.55 V stand-off voltage, and AEC-Q101 qualification for automotive-grade reliability - deployed in ECU power input stages and sensor interface protection.
For engineers reviewing the P6KE10HE3/73 datasheet, P6KE10HE3/73 pinout, P6KE10HE3/73 application, or P6KE10HE3/73 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and validated automotive-grade compliance status - critical for robust transient protection design in harsh environments.
Technical Context
The P6KE10HE3/73 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients. Its uni-directional polarity uses a cathode band marking and exhibits 3.5 V forward voltage at 50 A, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient).
It complies with AEC-Q101 stress testing for automotive applications and supports repetitive surge duty cycles up to 0.01 %, with clamping voltage tightly specified at 14.5 V under 41.4 A IPPM - ensuring predictable voltage limiting during load dump or inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (10/1000 μs waveform) - sustains high-energy surges without failure in automotive load-dump scenarios |
| Stand-off Voltage (VWM) | 8.55 V - maximum continuous reverse voltage before leakage exceeds 10 μA; sets operating margin below breakdown |
| Breakdown Voltage (VBR) | 9.50–10.5 V at 1 mA test current - defines onset of avalanche conduction; ensures reliable triggering above normal rail |
| Clamping Voltage (VC) | 14.5 V at 41.4 A IPPM - limits transient voltage seen by downstream ICs; enables safe operation of 12 V systems |
| Peak Pulse Current (IPPM) | 41.4 A (10/1000 μs) - quantifies maximum surge current the device can shunt while maintaining clamping spec |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood automotive deployment and industrial ambient extremes |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Value: Provides 14.5 V clamping ceiling compatible with 12 V bias rails, reducing need for higher-voltage-rated downstream components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same 10 V nominal breakdown, but 400 W peak power (vs. 600 W), SMA package (surface-mount) | Limited to PCB space-constrained consumer designs; not AEC-Q101 qualified | Select when board area is critical and automotive qualification is unnecessary |
| 1.5KE10A | Same DO-15 package and 600 W rating, but commercial-grade (no AEC-Q101), higher VF (3.5 V @ 50 A same) | Approved for industrial/computer use only; lacks automotive stress validation | Choose for cost-sensitive non-automotive applications requiring identical form factor and power rating |
Compared with SMAJ10A and 1.5KE10A, the P6KE10HE3/73 uniquely combines AEC-Q101 qualification, 600 W capability, and DO-15 through-hole mounting - making it the only option among the three validated for under-hood automotive deployment without derating or redesign.

FAQ
What is the clamping voltage of P6KE10HE3/73 at its rated peak pulse current?
The P6KE10HE3/73 has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM), measured under the standard 10/1000 μs waveform. This value ensures that downstream 12 V logic and analog circuits remain within safe operating limits during surge events, and is confirmed in the Vishay datasheet Document Number 88369, Table on page 2.
Is P6KE10HE3/73 suitable for automotive applications?
Yes, the P6KE10HE3/73 is AEC-Q101 qualified - explicitly stated in the Vishay datasheet revision 18-Sep-12, Note (1) on page 3 and Ordering Information section. This certification covers stress tests including high-temperature reverse bias, high-temperature operating life, and temperature cycling, validating its use in engine control units, body electronics, and ADAS sensor modules.
What does the "HE3" suffix indicate in P6KE10HE3/73?
The "HE3" suffix in P6KE10HE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Per the Vishay datasheet, HE3 devices undergo enhanced reliability screening versus standard E3 parts, and are intended for automotive and high-reliability industrial use - distinct from commercial-grade E3-only variants.
How does P6KE10HE3/73 differ from P6KE10A-E3/73?
The P6KE10HE3/73 is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance, whereas P6KE10A-E3/73 is commercial-grade (E3 only) with Class 1A whisker resistance. Both share identical electrical specs (VWM = 8.55 V, VC = 14.5 V), DO-204AC package, and 600 W rating - but only P6KE10HE3/73 is approved for automotive under-hood deployment per manufacturer documentation.
What is the thermal resistance of P6KE10HE3/73, and how does it affect layout?
The P6KE10HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. In PCB layout, this means adequate copper pour on anode/cathode pads and short, wide traces are essential to maintain junction temperature below 175 °C during repetitive surges - especially critical in enclosed automotive enclosures where ambient may exceed 105 °C.
