Product details
Overview
P6KA10AHE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 9.5 V minimum breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A, and operates up to +185 °C junction temperature - deployed in automotive power line and sensor interface protection.
For engineers reviewing the P6KA10AHE3/73 datasheet, P6KA10AHE3/73 pinout, P6KA10AHE3/73 application, or P6KA10AHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility, low 10 μA reverse leakage at VWM, and verified clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation. Its unidirectional polarity enables integration into DC-biased circuits where forward conduction must be preserved during clamping events.
The device delivers consistent 600 W peak pulse power handling with a 10/1000 μs waveform at 0.01 % duty cycle, and exhibits low incremental surge resistance to minimize voltage overshoot during fast transients such as inductive load switching or ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage before significant leakage; ensures reliable blocking in 8 V nominal supply rails. |
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA - Tight breakdown tolerance enables precise overvoltage threshold setting without margin overdesign. |
| VC @ IPPM | 14.5 V at 41.4 A - Clamping voltage remains below 15 V during full-rated surge, protecting downstream 12 V logic and analog ICs. |
| IPPM | 41.4 A - Peak pulse current capability supports IEC 61000-4-5 Level 4 (4 kV) surge immunity in automotive front-end designs. |
| TJ max. | +185 °C - Enables placement near hot components (e.g., power MOSFETs, engine control units) without derating concerns. |
| Leakage @ VWM | 10 μA at 25 °C; 20 μA at 150 °C - Low leakage preserves battery life in always-on automotive modules and avoids false triggering. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 9.5 mm body length, compatible with legacy through-hole assembly and automated taping. |
Pinout & Package
Package: DO-204AC (DO-15), molded epoxy case with matte tin-plated leads; cathode indicated by color band; RoHS-compliant and AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node in unidirectional configuration; allows normal DC bias while enabling clamping to ground during positive transients. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail, CAN-H); avalanche conduction initiates when line voltage exceeds VBR, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - suitable for under-hood ECUs and ADAS sensors. |
| 185 °C junction rating | Enables operation in high-ambient environments (e.g., near power converters or engine compartments) without thermal derating penalties. |
| 600 W peak pulse power (10/1000 μs) | Meets ISO 7637-2 Pulse 1, 2a, 3a/b and IEC 61000-4-5 surge requirements for 12 V systems with minimal PCB footprint. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing stress on downstream MOSFETs, microcontrollers, and transceivers. |
| Matte tin plating & JESD 201 Class 2 whisker resistance | Ensures long-term solder joint integrity in high-reliability applications, eliminating risk of tin whisker-induced short circuits. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units (ECUs) against load dump and inductive switching transients. IC Role / Device Role: Unidirectional TVS diode placed between battery rail and local regulator input. Use Value: Clamps transients to ≤14.5 V, preventing damage to 12 V LDOs and MCU power domains while maintaining AEC-Q101 compliance. |

IC Role / Device Role: Line-side TVS connected between signal conductor and system ground. Use Value: Limits induced surges to <15 V, preserving ADC reference integrity and avoiding saturation or latch-up in signal conditioning amplifiers. |
| Telecom DC Power Feeds | Consumer Appliance Motor Control |
Use Scenario: Overvoltage suppression on -48 V DC power inputs of telecom base station line cards. IC Role / Device Role: Reverse-connected unidirectional TVS referenced to chassis ground. Use Value: Withstands repeated 600 W surges without degradation, ensuring uptime in outdoor cabinet installations exposed to lightning-induced coupling. |
Use Scenario: Protecting gate drivers and microcontroller I/O in washing machine motor inverters subjected to brush-commutator noise. IC Role / Device Role: TVS placed across half-bridge driver supply pins and across motor phase outputs. Use Value: Fast response (<1 ns) and low dynamic impedance suppress sub-microsecond spikes, preventing false triggering of overcurrent protection. |
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 | Same DO-214AC (SMA) package; 10 V VWM, 11.1 V VBR min, 17 V VC @ 35.7 A; 400 W PPPM rating. | Lower power rating and higher clamping voltage reduce margin in automotive load-dump scenarios. | Preferred for space-constrained PCBs where surface-mount is mandatory and surge levels are ≤Level 3. |
| 1.5KE10A | DO-201AD package; 8.55 V VWM, 9.5 V VBR min, 14.5 V VC @ 41.4 A; identical electrical specs but rated for 1500 W (10/1000 μs). | Larger package and higher surge rating suit industrial mains-connected equipment requiring extended lifetime under repeated stress. | Select when board layout accommodates larger axial package and long-term surge endurance beyond automotive duty cycles is required. |
Compared with SMAJ10A and 1.5KE10A, the P6KA10AHE3/73 offers optimal balance of AEC-Q101 qualification, DO-15 footprint, and 600 W surge capability - making it the preferred choice for cost-sensitive, high-volume automotive and industrial through-hole designs where thermal stability up to 185 °C is critical.

FAQ
What is the maximum clamping voltage of the P6KA10AHE3/73 under full-rated surge current?
The P6KA10AHE3/73 has a maximum clamping voltage (VC) of 14.5 V at its rated peak pulse current of 41.4 A (10/1000 μs waveform). This value is guaranteed per the Vishay datasheet and reflects worst-case performance at TA = 25 °C, ensuring downstream 12 V ICs remain within safe operating limits during surge events.
Is the P6KA10AHE3/73 qualified for automotive applications?
Yes, the P6KA10AHE3/73 is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. Its construction - including passivated anisotropic rectifier technology, matte tin-plated leads, and JESD 201 Class 2 whisker resistance - meets automotive reliability requirements for engine control, body electronics, and ADAS subsystems.
What does the "HE3/73" suffix indicate in P6KA10AHE3/73?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101 qualified packaging with matte tin plating and JESD 201 Class 2 whisker resistance. The "/73" indicates tape-and-reel packaging in 73-inch reels - standard for DO-15 axial devices at Vishay, supporting automated through-hole insertion.
How does the P6KA10AHE3/73 differ from the non-A variant P6KA10?
The P6KA10AHE3/73 has tighter breakdown voltage tolerance (9.50–10.5 V vs. 9.00–11.0 V for P6KA10) and lower maximum reverse leakage (10 μA vs. 20 μA at VWM). These improvements enhance precision clamping and reduce standby power loss in battery-critical automotive modules.
Can the P6KA10AHE3/73 be used in bidirectional configurations?
No - the P6KA10AHE3/73 is unidirectional only, as confirmed in the Vishay datasheet. For bidirectional transient suppression (e.g., AC lines or data bus protection), a dedicated bidirectional TVS such as P6SMB10CA or SMAJ10CA must be selected instead.
