Product details
Overview
P6KA10HE3/73 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 P6KA10HE3/73 datasheet, P6KA10HE3/73 pinout, P6KA10HE3/73 application, or P6KA10HE3/73 equivalent, key selection criteria include unidirectional polarity, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification, clamping performance under 40 A surge, and thermal stability across -65 °C to +185 °C junction range.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its unidirectional structure provides low forward voltage (VF = 3.5 V at 50 A) and fast response to transients while maintaining stable clamping under repetitive 0.01 % duty cycle surges.
The device is rated for 600 W peak pulse power (10/1000 μs), 75 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a temperature coefficient of VBR = 0.073 %/°C - enabling predictable voltage clamping behavior across wide ambient and junction temperature ranges in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.10 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 9.0–11.0 V at IT = 1.0 mA - precise voltage threshold triggering avalanche conduction during overvoltage events |
| VC (Clamping Voltage) | 15.0 V at IPPM = 40.0 A - limits downstream circuit voltage during 10/1000 μs surge, protecting ICs and MOSFETs |
| PPPM (Peak Pulse Power) | 600 W - sustains standardized 10/1000 μs transient energy without failure; critical for ISO 7637-2 and IEC 61000-4-5 compliance |
| TJ max. | +185 °C - enables use in under-hood automotive modules and high-temperature industrial enclosures without derating |
| Polarity | Unidirectional - blocks reverse voltage only; requires correct orientation relative to protected line polarity |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, molded epoxy case with UL 94 V-0 rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to lower-potential side (e.g., ground or return rail); completes clamping loop during surge |
| Cathode | Protected line connection / transient sink | Connected to line being protected (e.g., 12 V supply); conducts avalanche current to anode when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Enables stable leakage performance (<20 μA at VWM, TJ = 150 °C) and long-term reliability in humid/harsh environments |
| 185 °C junction capability | Supports operation in engine control units, powertrain modules, and industrial motor drives without thermal shutdown |
| 600 W peak pulse power (10/1000 μs) | Withstands automotive load dump and inductive switching transients per ISO 7637-2 Pulse 5a without degradation |
| AEC-Q101 qualification | Validates suitability for automotive electronics per stress test requirements including HTGB, AC/DC life test, and ESD HBM ≥ 8 kV |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD, relay bounce), improving system immunity |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges above 15 V.

IC Role / Device Role / Timing Role: TVS connected across differential signal pair or single-ended output to ground. Use Value: Responds in <1 ns to 8 kV contact ESD (IEC 61000-4-2), limiting induced voltage to <15 V and preserving ADC accuracy. |
| Telecom Line Surge Suppression | Consumer Power Adapter Input Protection |
Use Scenario: Safeguarding PoE-powered devices (e.g., IP cameras) from lightning-induced surges on Ethernet pairs. IC Role / Device Role / Timing Role: Unidirectional TVS used in common-mode configuration on data lines referenced to chassis ground. Use Value: Handles 10/1000 μs surges up to 600 W while maintaining <1 pF junction capacitance - no signal integrity impact at 100 Mbps. | Use Scenario: Adding secondary overvoltage protection on AC-DC adapter DC output rails feeding USB-C PD controllers. IC Role / Device Role / Timing Role: TVS placed after primary regulation stage to absorb residual switching spikes and hot-plug transients. Use Value: Withstands 75 A 8.3 ms surge (IFSM), ensuring survival during repeated plug-in events without parameter shift. |
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 DO-214AC package; 10 V VWM, but lower PPPM = 400 W and higher VC = 16.0 V at 32.9 A | Limited to lower-energy transients; not AEC-Q101 qualified | Select for cost-sensitive consumer applications where 600 W rating and automotive qualification are unnecessary |
| 1.5KE10A | DO-201AD package; same VWM/VBR range but higher VF (4.5 V), larger footprint, and no AEC-Q101 validation | Requires PCB layout change; suited for legacy industrial designs with existing 1.5KE footprints | Choose only if board space allows larger case and AEC-Q101 compliance is not required |
Compared with SMAJ10A and 1.5KE10A, P6KA10HE3/73 delivers higher surge robustness (600 W vs. 400 W / 600 W with inferior clamping), guaranteed automotive qualification, and tighter VBR tolerance - making it optimal for next-generation automotive and high-reliability industrial systems where clamping precision and thermal resilience are critical.

FAQ
What is the maximum clamping voltage of the P6KA10HE3/73 under standard surge conditions?
The P6KA10HE3/73 has a maximum clamping voltage (VC) of 15.0 V at a peak pulse current (IPPM) of 40.0 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage during standardized surge events. The clamping performance is guaranteed across the full operating temperature range and forms the basis for system-level surge immunity design using the P6KA10HE3/73.
Is the P6KA10HE3/73 suitable for automotive applications?
Yes, the P6KA10HE3/73 is AEC-Q101 qualified and rated for TJ = -65 °C to +185 °C, making it suitable for under-hood and powertrain applications. Its construction uses passivated anisotropic rectifier technology, and it meets requirements for humidity resistance, thermal cycling, and surge endurance per automotive stress test standards. The P6KA10HE3/73 is explicitly listed in Vishay's AEC-Q101 qualified product matrix for transient suppression.
What does the "HE3" suffix indicate in P6KA10HE3/73?
"HE3" denotes RoHS-compliant, matte tin-plated leads that meet J-STD-002 solderability and JESD 22-B102 intermetallic growth requirements; it also satisfies JESD 201 class 2 whisker resistance. The "/73" indicates packaging in 73 mm tape-and-reel format (4000 pcs/reel). This suffix confirms the P6KA10HE3/73 meets environmental and assembly process requirements for modern SMT and through-hole manufacturing.
How does the P6KA10HE3/73 differ from the P6KA10A variant?
The P6KA10HE3/73 has a VBR range of 9.0–11.0 V at 1.0 mA, while P6KA10A specifies 9.5–10.5 V - indicating tighter breakdown tolerance. Both share identical VWM (8.10 V), VC (14.5 V), PPPM (600 W), and package (DO-204AC). The P6KA10HE3/73 is optimized for general-purpose robustness; P6KA10A targets applications needing tighter VBR matching, such as precision voltage reference protection circuits.
Can the P6KA10HE3/73 be used in bidirectional configurations?
No, the P6KA10HE3/73 is unidirectional only, as confirmed in the Vishay datasheet. It conducts avalanche current only when cathode voltage exceeds anode voltage by ≥VBR. For bidirectional protection (e.g., AC lines or differential signals), two P6KA10HE3/73 devices must be connected in series opposition, or a dedicated bidirectional TVS like SMBJ10CA should be selected instead of the P6KA10HE3/73.
