Product details
Overview
P6KA10HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 10 V standoff voltage (VWM), 9.0–11.0 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), 15.0 V clamping voltage at 40.0 A IPPM, and operates up to TJ = 185 °C - deployed in automotive power supply rails and industrial sensor interfaces.
For engineers reviewing the P6KA10HE3/54 datasheet, P6KA10HE3/54 pinout, P6KA10HE3/54 application, or P6KA10HE3/54 equivalent, key selection criteria include unidirectional polarity, DO-15 package compatibility, AEC-Q101 qualification, clamping performance under 40 A surge, and thermal stability up to +185 °C junction temperature.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for high reliability under repetitive surge stress. Its 10/1000 μs waveform rating of 600 W and low incremental surge resistance enable effective clamping during inductive switching transients.
The device is rated for TJ = –65 °C to +185 °C, supports 75 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a VBR temperature coefficient of +0.073 %/°C - confirming stable breakdown behavior across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.10 V - maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 9.0–11.0 V at IT = 1.0 mA - precise voltage threshold where avalanche conduction initiates reliably under transient stress. |
| VC (Clamping Voltage) | 15.0 V at IPPM = 40.0 A - limits downstream voltage during worst-case surge, protecting 12 V logic and power stages. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - sustains high-energy transients without failure; validated per ANSI/IEEE C62.35. |
| ID (Reverse Leakage) | 10 μA max at VWM, TJ = 25 °C; ≤20 μA at TJ = 150 °C - ensures minimal standby power loss in always-on systems. |
| TJ max. | +185 °C - enables placement near hot components (e.g., power MOSFETs, engine control units) without derating. |
| AEC-Q101 Qualified | Yes - certified for automotive electronic modules requiring proven reliability under temperature cycling, humidity, and mechanical stress. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case meeting UL 94 V-0. Cathode indicated by color band. Matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102; HE3 suffix passes JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to ground or low-impedance reference; completes clamping loop during positive transients on cathode side. |
| Cathode | Protected line connection | Placed in series with input rail (e.g., 12 V battery feed); conducts avalanche current when line exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage after 1000+ surge cycles. |
| High-temperature operation | TJ = 185 °C capability allows direct mounting on engine control boards without thermal derating. |
| Fast response time | <1.0 ps intrinsic response - clamps transients before IC damage thresholds are exceeded (e.g., <100 ns propagation delay). |
| Low incremental surge resistance | Ensures VC remains tightly bounded even at 40 A IPPM, minimizing voltage overshoot into protected circuitry. |
| AEC-Q101 qualification | Validated for automotive underhood applications including powertrain, body control, and ADAS sensor power inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC (SMA) package; 10.0 V VWM; 15.4 V VC at 38.9 A; 400 W PPPM; TJ = 150 °C max. | Limited to lower-temperature environments; not AEC-Q101 qualified; smaller footprint but lower surge rating. | Select SMAJ10A only for cost-sensitive consumer designs where AEC-Q101 and 185 °C operation are unnecessary. |
| 1.5KE10A | DO-201AD package; 10.0 V VWM; 16.0 V VC at 37.5 A; 1500 W PPPM; TJ = 175 °C; higher VF (3.5 V @ 50 A). | Higher peak power but larger size and higher clamping; lacks AEC-Q101 certification and 185 °C rating. | Choose 1.5KE10A for legacy industrial systems needing higher single-pulse energy absorption, accepting larger PCB area and no automotive qualification. |
Compared with SMAJ10A and 1.5KE10A, P6KA10HE3/54 uniquely combines AEC-Q101 qualification, +185 °C operation, DO-15 form factor, and 600 W capability - making it the only option qualified for under-hood automotive use with minimal layout impact.

FAQ
What is the clamping voltage of the P6KA10HE3/54 under maximum surge conditions?
The P6KA10HE3/54 has a maximum clamping voltage (VC) of 15.0 V at a peak pulse current (IPPM) of 40.0 A, measured using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuits remain within safe voltage margins during transient events. The P6KA10HE3/54 maintains this clamping performance due to its low incremental surge resistance and stable avalanche characteristics.
Is the P6KA10HE3/54 suitable for automotive applications?
Yes, the P6KA10HE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS power supplies. Its DO-15 package, unidirectional polarity, and 600 W surge capability align with ISO 7637-2 and ISO 16750-2 test requirements. The P6KA10HE3/54 meets these standards without derating in typical vehicle thermal environments.
What does the HE3/54 suffix indicate in P6KA10HE3/54?
The HE3 suffix denotes RoHS-compliant, matte tin-plated leads that pass JESD 201 Class 2 whisker testing, while the /54 indicates packaging in 13-inch diameter paper tape and reel with a base quantity of 4000 units. This configuration ensures compatibility with automated SMT placement equipment and satisfies automotive supply chain traceability requirements. The P6KA10HE3/54 is supplied in this format to support high-volume manufacturing without lead finish or packaging rework.
How does the P6KA10HE3/54 compare to bidirectional TVS diodes?
The P6KA10HE3/54 is unidirectional only and intended for DC line protection where polarity is fixed - such as 12 V battery feeds or regulated DC outputs. Unlike bidirectional devices, it provides lower leakage and sharper knee characteristics in forward-biased operation. For AC or floating signal lines, a bidirectional variant would be required; the P6KA10HE3/54 is not suitable for those topologies due to its inherent polarity asymmetry.
What is the maximum reverse leakage current of the P6KA10HE3/54 at elevated temperature?
At TJ = 150 °C, the P6KA10HE3/54 exhibits a maximum reverse leakage current (ID) of 20 μA when biased at its 8.10 V standoff voltage (VWM). At room temperature (25 °C), ID is limited to 10 μA max. This controlled leakage ensures minimal power loss in always-on automotive modules and preserves signal integrity in precision sensor interfaces. The P6KA10HE3/54 maintains these values across its full qualified temperature range without degradation.
